PREFACE TO THE FIRST EDITION.
Since the days of Sir W. Jones, Sanskrit litera-

ture, in almost every department, has been zealous-
ly ransacked by scholars, both European and Indian.
As the results of their labours we are now in poss-
ession of ample facts and data, which enable us to
from some idea of the knowledge of the Hindus of
^ old in the fields of Philosophy and Mathematics in-
cluding Astronomy, Arthmetic, Algebra, Trigono-
^^ metry and Geometry. Even Medicine has re-
) ceived some share of attention. Wilson in a se-
ries of essays published in the Oriental Magazine
(1823), Royle in his Antiquity of Hindu Medicne
(1837), and Wise in his commentary on the Hindu
System of Medicine (1845}, were amongst the first
to bring to the notice of the European world the
contents of the ancient medical works of the Hin-
dus, and recently the Thakur Sahib of Gondal has
added his quota. These contributions are, how-
! ever, of a fragmentary nature. A comprehensive
history of Hindu medicine has yet to be written.

Materia Medica has also found, in Udoy Chand
Dutt, an able exponent. One branch has, however,
up till this time, remained entirely neglected
namely, Chemistry. Indeed, it may be assumed
that on accont of its complex and technical nature
it has hitherto repelled investigators.
The progress of chemical knowledge among the
ancient nations has always had a fascination for
me. The classical works of Thomson, Hoefer
and Kopp have been my favourite companions for
the last twelve years and more. In the course of
my studies in this field I was naturally led to an
inquiry into the exact position which India occu-
pies therein, and with this view I undertook a sys-
tematic examination, from the chemical standpoint,
of the Charaka, the Suj-ruta and the various stan-
dard works of the Ayurvedic and latro-chemical
Periods, which have escaped the ravages of time. It
was at this stage that I was brought into communi-
cation with M. Berthelot some five years ago a
circumstance which has proved to be a turning-
point, if I may so say, in my career as a student of
the history of chemistry. The illustrious French
savant, the Doyen of the chemical world, who has
done more than any other person to clear up the
sources and trace the progress of chemical science
in the West, expressed a strong desire to know all
[ 3 ]
about the contributions of the Hindus,"^ and even
went the length of making a personal appeal to me
to help him with information on the subject. In
response to his sacred call I submitted to him, in
1898^ a short monograph on Indian alchemy; it was
based chiefly on Rasendrasara Samgraha^ a work
which I have since then found to be of minor im-
portance and not calculated to throw much light on
the vexed question as to the origin of the Hindu
Chemistry. M. Berthelot not only did me the ho-
nour of reviewing it at lengtht but very kindly pre-
sented me with a complete set of his monumental
work, in three volumes, on the chemistry of the

*"Cependant il serait n^cessaire d'examiner certains docu-
ments qui m'ont ^t^ r^cemment signales par une lettre de RAy,
professeur a Presidency College (Calcutta). D'apres ce savant, il
existe des trait^s d'alchimie, Merits en Sanscrit, remontant auxiiie
sicle, et qui renferment des pr^ceptes pour preparer les sulfures
de mercure noir et rouge et le calomel employes comme medica-
ments. Ces indications s'accordent avec celles des alchimistes arabes
signalês plus haut. II est ^ d^sirer que ces trait<?s soient soumis
k urie etude approfondie, pour, en determiner I'origine, probable-
ment attribuable k une tradition persane ou nestorienne."

Middle Ages, dealing chiefly with the Arabic and
Syrian contributions on the subject, the very exis-
tence of which I wa^ not till then aware of. On
perusing the contents of these works I was filled
with the ambition of supplementing them with one
on Hindu Chemistry. Although I have written all
along under the inspiration of a mastermind, it is
not for f. moment pretended that my humble pro-
duction will at all make an approach to the exem-
plar set before my eyes.
When I first drew up the scheme of the present
work, I had deluded myself with the hope of finish-
ing the study of all the available literature on the
subject before I took to writing. But I soon found
that the task was one of vast magnitude. Some
of my friends, whose judgment is entitled to weight,
advised me under the circumstances, to curtail the
scope of the work as originally planned out, and
present a first instalment of it in its necessarily de-
fective and imperfect shape (see Introduction, p.
Ixxxiv), reserving for a subsequent volume the work-
ing-up of the materials which are accumulating
from time to time. In the present volume only
one or two representative works of the Tanric and
latro-chemical Periods have been noticed at length.
As regards the transliteration, I have not rigid-
ly adhered to any particular system, but, in the
[ 5 ]
main, I have followed that of the Sacred Books of
the East,
Before concluding, I must acknowledge the valu-
able assistance I have received rom Pandit Nava-
kiinta Kavibhusawa with whom I have toiled
through many an obscure passage of the Mss. of
the Tantras. His sound knowledge of the Ayur-
vedas has also been of much help to me.
X- -Jf -Jf *
And now it only remains for me to discharge
the grateful duty of expressing my thanks to the
Government of Bengal, which at the instance of Mr.
Alexander Pedler, F. R. s., Director of Public Ins-
truction, placed a liberal grant at my disposal to
enable me to meet various incidental expences,
chiefly in the matter of collecting rare Mss.

PREFACE TO THE SECOND EDITION.

A comparatively limited number of copies was
printed in the first edition as it was feared that
owing to its technical nature the work would
appeal only to a select circle of readers. The
exceedingly favourable reception accorded to it
not only by the scientists and orientalists but also
by the public in general both in Europe and in
India has necessitated the bringing-out of a second
edition. Some material additions have been made
to the historical portion of the Introduction, throw-
ing further light on the independent origin of the
Hindu system of medicine and its priority to that
of the Greeks.
M. Berthelot, in the course of a lengthy and
appreciative review in the " Journal des Savants,"
Jan. 1903, expresses his regret at the absence of
*' any thing which would remind us of the system-
atic treatises of Zosimus and of the Greco-Egyptians''
a regret which will be shared in by every student
of Hindu chemistry. But even the sable cloud is
not without its silver lining. I hope, however, to
deal with the theories underlying Hindu chemistry
in the second volume. For the present, I have to
[ 7 ]
content myself with the pronouncement of my res-
pected and learned friend, Mr. Brajendranatha Seal
Principal, Maharaja's College, Kuch Behar, whose
vast acquaintance with and comprehensive grasp of,
the literature of the East and the West, entitles him
to speak with authority on the subject. Says Mr.
Seal in his plea for our University ^^ striking out a
line of communication with the organisations of
oriental learning.''
'^ Let us not superciliously dismiss these studies
as ' learned lumber.' The Astronomy and Ma-
thematics were not less advanced than those of
Tycho Brahe, Cardan and Fermat ; the anatom}
was equal to that of Vesalius, the Hindu logic
and methodology^ more advanced than that of
Ramus, and equal on the whole to Bacon's ; the
physico-chemical theories as to combustion, heat,
chemical affinity, clearer, more rational, and more
original than those of Van Helmont or Stahl ; and
the Grammar, whether of Sanskrit or Prakrit, the
most scientific and comprehensive in the world
before Bopp, Rask and Grimm."

Introduction
Alchemical ideas In the Vedas

In tracing the progress of chemical know-
T. r J ledge amonfi: the civilized
Dawn of Hindu ^ ^
Alchemy. nations of old, one always
finds it intimately associated with medicinal
preparations, metallurgical operations, the
technical arts and the belief in the transmu-
tation of metals. In India^ more so than in
Europe, chemistry has, however, been evolved
chiefly as a handmaid of medicine ; and, some-
what later on, as an adjunct of the Tantric
cult. The efficacy of the drug alone was by
no means considered sufficient unless backed
by the kindly interposition of the deities.
Thus in the /figyeda, we find the A^vins, the
divine physicians, invoked, who give sight to the
blind and make the lame walk. These twin
gods have many points in common with the
Dioskouroi of Greek mythology. One very

11
curious myth is that of the maiden Vi^pala

who, having had her leg cut off in some con-
flict, was at once furnished by the A^vins with
an iron limb.
The higher gods of the îgveda are al-
most entirely personifications of the elements
and the other natural phenomena, such as
the fire and the wind, the sun and the dawn.
But we often find also herbs and plants en-
dowed with potent and active properties,
raised to the dignities of the gods and ad-
dressed as such. The Soma plant is an
object of particular adoration and the Vedic

ing effects of the fermented juice expressed
from it. ' The Soma rasa ( juice ) began

Again, in another hymn we read : ** O

King Varuwa ! a hundred and a thousand
medicinal drugs are thine/'
It is in the " Atharva-veda '* however, that
plants and vegetable products in general are
fully recognised as helpful agents in the treat-
ment of diseases, though their use is invari-
ably associated with the employment of
charms, spells, and incantations. Thus the
plant apamarga (achyranthes aspera), which
still occupies a prominent place in the Hindu
system of medicine as a di-uretic and laxative
etc., is invoked as the ** mistress of remedies''
(IV. 17, I.) and **sole ruler overall plants."
In another hymn the Soma plant is thus
referred to :
'* The strength of this amr^ta (ambrosia)
do we give this man to drink. Moreover, I
prepare a femedy, that he may live a hundred
years !"
Again, '* as many (plants), as the human
physicians know to contain a remedy, so many,
endowed with every healing quality, do I apply
to thee !*' ^ Here is a spell for the cure of

leprosy by means of a dark- coloured plant :
Born in the night art thou, O herb,
Dark- coloured, sable, black of hue :
Rich-tinted, tinge this leprosy,
And stain away its spots of grey ! (1.23,1).
Macdonell
There is also a distinct reference to a
remedy for promoting the growth of hair.
** As a goddess upon the goddess earth
thou wast born, O plant ! We dig thee up, O
nitatni, that thou mayest strengthen (the
growth) of the hair.
*' Strengthen the (old hair), beget the
new ! That which has come forth render more
luxurious!^' VI. 136. 1-2.

plicity which is the characteristic beauty, of

the /?/gveda, one Rishi says pathetically of-
himself :
*' Behold I am a composer of hymns, my
father is a physician, my mother grinds corn
on stone. We are all engaged in diflferent
occupations*'* (IX. 112, 3),
*^ Princes like Divodasa, and bards and
leaders of the tribe of the Angiras, adminis-
tered medicines and gloried in effecting cures.
A skilled physician is distinctly defined as one
who lives in a place abounding with medicinal
plants, and who assiduously devotes his time
to the acquisition of knowledge ^''

in the 7?/k, we can trace the

are deadly imprecations against evil-doers ;

magical incantations for bringing about ruin,

death, dementation and stupefaction of one^s
adversaries.; and charms intended to secure
the love of women through the potency of
various herbs. Some of them are of hostile
character, being meant to injure rivals. The
picture here presented has its counterpart in
the ancient Egyptians, who were noted for
their magical lore to which the Greeks were
no less attached. There is a close resem-
blance between the contents of the A. V". and
those of the Papyrus of Leyden in some es-
sential features. In the latter also there is
an intermixture of magic, astrology, alcherriy
as well as recipes for love philters.^
The A. v., on account of its frequent calling-
in-aid of super-natural agencies forselfish and
malevolent purposes, has not generally been
accorded the canonical sanctity of the Vedic
Triad The Riky the Yajus and the Saman ;

scripture has been questioned in the several

law-books of the Apastamba, the Vishwu, the
Yajnavalkya and the Manu schools, and the
practices it sanctions strongly condemned.
As Hindu medicine has seldom been able
to shake itself completely free from the influ-
ence of magic and alchemy as auxiliaries,
physicians, as practicers of the ** black art,"
have been given an inferior position in the
legal treatises. The Mahabharata, reflecting
the spirit of the above law-books, regards the
physicians as impure. In spite of this '' the
Atharvan retains in a measure its place by
virtue of its profound hold upon popular
beliefs, because the Atharvan performs,
especially for the king, inestimable services
in the injury and overthrow of enemies. '''

their object the securing of long life and health
are known as *'ayushya/zi'^ a term which
later on gave place to rasayana, the Sans-
krit equivalent of alchemy (see p. 80). We
shall quote two under the latter heading as
invocations to pearl and its shell and gold res-
pectively. *^ Born in the heavens, born in the
sea, brought on from the river (Sindhu), this
shell, born of gold, is our life- prolonging
amulet."
'^ The bone of the gods turned into pearl;
that, animated, dwells in waters. That do I
fasten upon thee unto life, lustre, strength,
longevity, unto a life lasting a hundred
autumns. May the (amulet) of pearl protect
thee!"
**The gold which is born from fire,^ the im-
mortal, they bestowed upon the mortals. He
who knows this deserves it : of old age dies
he who wears it."
^^ The gold, (endowed by) the sun with
beautiful colour, which the men of yore, rich
in descendants, did desire, may it gleaming

While gold is regarded as the elixir of life,
lead is looked upon as the dispeller of sorcery:
*' To the lead Varuwa gives blessing, to the
lead Agni gives help. Indra gave me the
lead ; unfailingly it dispels sorcery/''
It is of interest to note the alchemical
notions which had gathered round gold and
lead * at the time of the A. V.
To the student of Hindu medicine and al-
chemy, the A. V. is thus of special interest as
the earliest repository of information on the
subject.

In the latter the humoral pathology is fully

developed, the diagnosis and prognosis of
diseases described at length, and an elaborate
mode of classification adopted. We have
seen above that the physicians were
assigned rather dn inferior status in soci-
ety; the healing art was, in fact, never
recognised as a division of the Vedas/ Still
the claims of the indispensable science of
medicine, which can be distinctly traced to
the A. v., could not altogether be ignored,

success was the separatipn of the pursuits of the physician from

diversion of profitable gains from the ancient channel, could have
been accomplished without a struggle, We should reverence the
memory of Hippocrates for the complete manner in which he
effected that object." Draper's " Hist, of the Intellect. Dev. in
Europe," I. p. 393 (ed. 1896). The services rendered by Charaka,
SuCTuta and their predecessors were equally valuable.

(iityurveda) is regarded as a secondary or sub-

sidiary branch {updnga) of the Atharvan and
as a direct revelation of the gods (Siitra : Ch.
XXX. 8-9).
The Su^ruta even goes a step further and
asserts that the self-existent (BrahmA) crea-

is not a light one, and it is one of the most

We confess we are by no mieans convinced
of M. Levies theory. If we are to go by

quity for our author. The appellation of

in such rnatters we would do well to set
store by native traditions. It would be be-
side our purpose, however, to enter into any
lengthy discussion on the grounds on which
we are inclined to place Charaka in the
pre-Buddhistic era, but we shall summarise
below the salient points.

In the handling of the subject-matter the

Evidence based Charaka IS not SO Systematic
upon the handling of ^| r^ . i^'jt-
the subject-matter, as the Suûta, but mdulges
in random, hap-hazard and irrelevant discour-
ses, which make the reader often lose the
thread of the main narrative. The author^
whenever he has an opportunity, boldly
and with evident relish, launches into meta-
physical disquisitions, which, he believes,
make up for lack of experiments and obser-
vations. ' In this respect the Su^ruta is far
more scientific than the Charaka. The
Nyaya and the Vaiêshika systems of phi-
losophy, which have been interwoven into
the body of the text, again remind us of a
stage when they were more or less in a state
of flux, but had not crystallised into the
well-defined form and shape of the siitras
in which they have come down to us-this also

Bahler also points out that " the earlier history of the puranas,
which as yet is a mystery, yv\\\ only be cleared up when a
real history of the orthodox Hindu sects, especially of the Sivites
and Vishnuites, has been written. It will, then, probably become
apparent that the origin of these sects reaches back far beyond
the rise of Buddhism and Jainism." Intro, to "Apastamba," &c.

It should, however, be borne in mind
that the Charaka, as we now possess it, can
by no means lay claim to be the first compre-
hensive and systematic treatise on Hindu
medicine, it represents rather a more or less
final development of the subject, just as the
elaborate grammar of Pa^zini is based upon
some twenty previous works of his predeces-
sors, notably of Yaska, ^'akalya, âkatayana,
Gargya and others.
The above has its parallel in the history
of Greek medicine anterior to the time of
Hippocrates. As Draper observes :
" Of the works attributed to Hippocrates, many
Writings of Hip- ^^^ doubtless the production of
pocrates. j^jg family, his descendants, or his
pupils. The inducements to literary forgery in the
times of the Ptolemies, who paid very high prices

by Jolly as a " reason in favour of the high antiquity of its laws. "
Vide Intro, to Vishnu, pp. XVIII-XX. See also Jolly's "Medi-"
cine" (Grundriss), p. 42.

for books of reputation, have been the cause of

much difficulty among critics in determining - such
questions of authorship. The works indisputably
written by Hippocrates display an extent of know-
ledge answering to the authority of his name ; his
vivid descriptions have never been excelled, if indeed
they have ever been equalled. The Hippocratic
face of the dying is still retained in our medical
treatises in the original terms, without any im-
provement. '*
Still more appropriate are the remarks of
Littr^ on the works which now bear the name of
"the father of medicine."

Of internal evidence the first notable,
and internal evidence, feature is the Style.
The simple, unvarnished prose of the
Charaka reminds one of the Brahmawas of
the Vedas. Thanks to the researches of
Biihler and Fleet, we have now some idea
of the prose Kabya style as it existed in
the second century A. D. The literary prose
inscriptions discovered at Girnar and Nasik,
although less ornate and artificial than the
romances of Subandhu and Vaa (seventh
century A. D)., abound in long-winded
metaphors and alliterations and thus stand in
bold constrast with the simple prose of the
Charaka.
Between the period of the A. V. and that
of the Charaka there must have been com-
xxi
posed several medical treatises, each reflect-

ing the spirit and progress of its age\ At the
time of the Charaka itself there existed at
least six standard works by Agniveâ, Bhela,
Jatukarwa, Paraâra, Harita, and Ksharapa;zi,
respectively. Charaka simply based his work
on that of Agniveâ*, which he completely recast
and remodelled. Later on, DrzVAavala added
the last forty-one chapters'. The other five
works seem to have perished*. Vagbha/a,
(i) We are at present engaged in examining the Brahmawas,
the Upanishadas and Buddhistic literature with a view to glean in-
formation on these points and hope to announce the results in the
second volume.
(2) Charaka himself naively assigns his reasons for giving
preference to the treatise of Agnivesa in the words : "of the
six (authors) Agnivesa was the most "sharp of intellect" (siitra
Ch. I2.)

convenient abstract has led to the neglect and subsequent loss of
all earlier works on the subject." Intro, to Stein's Rajatarfigini,
p. 25. In Burnell's Tanjore catalogue Pt. I. pp. 63-65, a full ana-
lysis is given of Bhelasawhita, from which it would appear that
this work is still extant, though in a mutilated form. Dr. Burnell
xxii
the epitomiser of the Charaka and the Su^ruta,

mentions the works of Harita and Bhela,
which were probably extant in his days.
On reading the Charaka, one often feels as
if it embodies the deliberations of an interna-
tional Congress of medical experts, held in
the Himalayan regions to which even distant
Balkh (Bactriana) sent a repersentative in the
person of Kawkhaya/za (see p. 25). The
work professes to be more or less of the nature
of a record of the Proceedings of such a
Congress/
Bodas in discussing the philosophical
disquisitions of the Brahma;âs observes :
"It was a special function of the Brahma priest
to give decisions on any disputed points that may
remarks ; "the most superficial comparison shows how much
Vagbhaâ was indebted to this ancient work."
An "Harita Sawhita has recently been published ; but its au-
thenticity is questionable.

not have done unless he was a master of ratiocina-
tion. Such decisions, which may be likened to
the chairman's rulings in a modern assembly, are
scattered through the ancient Brahmawas, and are
collected together as so many Nyayas in the Purva
Mimsimss. aphorisms of Jaimini/' ^
We would invite the reader to go through
the '^Discourse on the Tastes^' (pp. 25-28)
and he will naturally agree that the above
remarks apply with equal force to our author.
In short, judging both from the manner and
the matter of the work,we have little hesitation
in placing it in the pre-Buddhistic era. We
shall revert to the subject under Su^ruta.
As regards the Su^ruta we are on more
-c? . ôlid grounds. Its termino-

logy and technique^ in genenal,
do not differ much from those of the Charaka.
In style the Su^ruta is rather dry, pithy, laco-
nic, and matter-of-fact, as the Charaka is
discursive and diffuse, and its composition al-
together would point to a much later date.
(i) Intro, to Annawbha^â's Tarkasawgraha, p. 28,

This is easily accounted for. The Su^ruta,

such as has been preserved to us, is generally
held to be a comparatively modern recension
by the celebrated Buddhist Chemist, Nagarju-
na,* who is said to have added the Uttaratan-
tra or the Supplement. ' Here for the first
time in the history of Hindu Medicine and
Chemistry, we come accross a personage
who is historical rather than mythical (see
below). That the redactor thoroughly recast
and remodelled the Su^ruta is evident from
the fact that there are numerous passages in
it which agree almost verbatim with the
Charaka, and which appears to have been
amply laid under contribution.

ed** *uttaratantra." Since that period it has been known by the
name of Susruta Samhita." Intrcductfon to " Vaidyakasabda-

The Su^ruta is par excellence a treatise
on surgery * as the Charaka is on medicine
proper. Ancient India must have acquired
considerable skill in the handling of the
lancet ; for in the Charaka we find a distinc-
tion drawn between the ** Kayachikitsakas/'
i, e, the physicians properly so called, and
the ** Dhanvantvarisampradayas '' i, e. fol-
lowers of Dhanvantvari or the Chirurgeons
a distinction which we have already noticed in
the beginning of the Vedic Age.
The age of Su^ruta has been the subject
of animated controversy for a long time past.
The Hindus regard this branch of Ayurveda
as a direct revelation from the A^vins or the
Divine Surgeons (see p. i, Intro.). The
origin of this myth can be traced to the
-^zgveda as already seen. In the Maha-
bharata, Suûta is spoken of as the son of
the sage Vi^vamitra and in the *' Varttikas '* of
Katyayana (about 4th century B. C.) we

also find mention of the same name. It is

not, however, easy to establish any connec-
tion between these names and our present
author. That there was a VWddha (old)
Su^ruta, exisiting as early as the fifth cen-
tury A. D., has now been established almost
beyond doubt. Dr. Hoernle, to whose pro-
found scholarship and indefatigable labours
the world is indebted for the excellent edition
of the Bower Ms., has deduced from
palaeographic evidence that it must have
been copied within the period from about
400 A. D. to 500 A. D. * di conclusion at
which Prof. Biihler has independently
arrived. The work professes to be by
Su^ruta, to whom it was declared by the Muni
Kaîraja. The origin of the Ayur/eda as
given in the Bower Ms., is on much the same
lines as in the Charaka and the mention in it,
among others, of such names as Harita,
Bhela, Parayara, and the Awins as founders
of the science of medicine, would go to prove
(i) On the date of the Bower Ms., See *'Journ. As. Soc."
LX. Pt. I. p. 79.
xxvu
that even so early as the 5th century A.. D.,

the old Su^ruta had eome to be regarded as
of mythical origin, and that therefore it must
have been composed many centuries anterior
to that time. Several important recipes as
given in the Bower Ms., e. g. those of the
'^chyavanapraâ,** **îlajatuprayoga" (the doc-
trine of bitumen p. 53) etc., occur in practically
identical recensions in the Charaka. This
is easily accounted for. The Charaka, the
Su^ruta, and the Bower Ms., and even the
Ash/afigahridaya of Vagbha/a have more or
less a common basis or substratum. In
order to understand this point more clearly
it is only necessary to refer for a moment to
the legal literature of the Hindus. The
^' Manava Dharmaâstra '' or the Institutes
of Manu, which still exercises a potent in-
fluence in the regulation of the social life of
the Hindus, is by no means the ancient work

It would equally be a great mistake to
suppose that the knowledge chemical and

is only representative of the time of its final
redaction. As a matter of fact it is a re-
pository of the informations on the subject
accumulated from the Vedic age to the date
of its final recasting. .
The remarks of M. Berthelot regarding

The period when the Su^rura received its
final cast must always remain an open ques-
tion. Vagbha/a in his Ashtangahridaya makes
copious extracts both from the Gharaka and
the Su^ruta. The latter must therefore have
existed in their present form prior to the 9th
century A. D. Madhavakara in his Nidana
quotes bodily from the Uttaratantra, and as the
Nidana was one of the medical works which
were translated for the Caliphs of Bagdad (see
below), it can safely be placed in the 8th
century at the latest. In is thus evident
that the present redaction of the Su^ruta
must have existed anterior to that date, and
that it had become at that age stereotyped
as it were. The Vagbha/a and the Nidana
are simply summaries of the Charaka and
Suûta, ' and were written at a time when

the latter had become very old, and were

therefore studied by few experts, and their
abstracts were likely to be prized by the
general practitioners.
Vagbha/a concludes his masterly treatise
with the following observation, which is
highly significant :

Medicine are to be looked for in the writings
of Galen and Hippocrates ; indeed he goes
so far as to suggest that the very name of
Su^ruta is derived from the Arabic word
Sukrat ( Sokrates), which is often con-
founded with Bukrat, the Arabic corruption
of the Greek Hippocrates/ There is cer-
tainly a strange similarity between the chap-

In the Atharva-veda, which may be looked
upon as the parent of the Ayurveda, we
naturally come across ample evidences of
an ingrained belief in the causation of
diseases by the disturbance of the humors.

"The history of the interpretation of this hymn is of uncommon
interest, because it illustrates forcibly the particular closeness of
relation between the hymns of the Atharvan and the practices
reported in connection with them. Professor Weber, Indische
Studien, IV, p. 405, translated the hymn under the caption
* Gegen hitziges fieber,' and guided especially by the more im-
mediate meaning of g-ardiyugaJi, 'the product of the placenta,
after-birth,* he thought that the hymn referred to puerperal fever,
or the fever of a child. Ludwig, Der Rigveda, III, p. 343, sur-
mised that the hymn was directed aginst inflammation, and
Zimmer, Altindisches Leben, p. 390, refers to it in connection
with the word vfllta in the first stanza, which he would translate
by ' wound ;* he also identifies vata with * wound * etymologically.
The compound vatabhrcL^&s in the first stanza, as he understands,
means 'suffering from wound-fever.' But Zimmer's theory that
the word vdta ever means ' wound ' has not sustained itself : vata
is 'wind in the body;' vatfkn'tanasant (VI,44,3^) is .' destroyer of th'e
disease which comes from wind (of the body) ;' cf. bata byadhi

too firm a hold to be easily eradicated. As Dr. Johnson ob-
serves :" "Modern writers are the moons of literature ; they shine
with reflected light, with light borrowed from the ancients.
Greece appears to me to be the fountain of knowledge."
Thanks, however, to the recent researches of orientalists, this
notion is fast disappearing. The late Prof. Max Miiller, who
always held the balance evenly in deciding between the rival
claims ot the East and the West, in his last work, thus gives
expression to the European sentiment : "In some respects, and
particularly in respect to the greatest things , India has as
much to teach us as Greece and Rome, nay, I should say more.
We must not forget, of course, that we are the direct intellectual
heirs of the Greeks, and that our philosophical currency is fallen
from the capital left to us by them. Our palates are accustomed
to the food which they have supplied to us from our very child-
hood, and hence whatever comes to us now from the thought-
mines of India is generally put aside as merely curious or str inge,
whether in language, mythology, religion, or philosophy. "Aiild

much to complain that classical scholars, for instance, should
have a decided repugnance to admit any actual influence on
Greek thought or institutions as having been exercised by the
thinkers of the East, however ungrudgingly that privilege is
conceded to Egypt. Personally I think that they are quite in
the right in maintaining that such an influence is, except in a few
instances, at present entirely unproven. But surely there are
many points of analogy which are most instructive, and suggestive
at least of more than an analogical connection ; points that may
throw light upon the natural course of the evolution of human
conceptions and, in doing so, help to throw light on dark corners
of the history of that culture out of which our own has arisen.
It is a common saying that it is impossible to know any one
language well without at the same time knowing another, and I
venture to think that a similar remark holds good of the history of
religion or of ethics, or of institutions, or of philosophy."

books ! The idea that anything could come from the East

and modern thinkers. We in the West have done some good
work too, and I do not write to depreciate the achievements of
the Hellenic and Teutonic mind. But I know that on some of
the highest problems of human thought the East has shed more
light than the West, and by and by, depend on it, the West will
have to acknowledge it. There is a very able article in the last
number of the Edinburgh Review (Jan. 1881), on Dr. Caird's

England, and more familiar than most Englishmen with the solid
work of modern German philosophers. And what is the last
result at which Dr. Caird arrives, and of which even the Edinburgh
Review approves ? Almost literally the same as the doctrine of
the Upanishads ! Dr. Caird writes : ' It is just in this renunci-
ation of self that I truly gain myself ; for whilst in one sense we
give up self to live the universal and absolute life of reason, yet
that to which we thus surrender ourselves is in reality our truer
self/ And again : ' The knowledge and love of God is the giving

can be given to the syllogism of inductive logic. But European
logicians cannot get over the idea that there is no logic like that
of our school-men, and that every deviation from it is a mistake.
" The same conceit runs through almost all that is written on
India. India may be patronised, some works of Indian poets and

Indian native opinion, that is out of the question.

the testimonies of Wim. and of the Chinese
pilgrim, I-Tsing. Thus, we read in the
Harsha-Charita : "among their number, how-
ever, was a young doctor of Punar\'asu's racie
named Rasayana, a youth of about eighteen
years of age, holding an hereditary positipn
in the royal household, in which he had been
cherished like a son by the King. He hacj
mastered Ayurveda in all its eight divisions,

perfectly familiar with the diagnosis af diseas-

successful study in medical science, but as it
is not my proper vocation, I have finally
given it up.''* In his rules on giving medi-
cine he further lays stress on abstinence and
fasting and recommends such drugs as the
myrobalans, ginger, pepper, liquorice, etc

The Transitional Period

Circa 800 1 100 A, D.
V/?/NDA AND CHAKRAPAiVl
We now come upon a period which deter-
mines the parting of ways in the progress of
Hindu medicine. Hitherto we have been
chiefly concerned with herbs and simples and
a few readily available products of the mine-
ral kingdom. About the year 1050 A. D.
Chakrapa/î Datta, himself a learned commen-
tator of both the Charaka and Su^ruta, wrote
the celebrated medical treatise which bears
his name. Since the days of Vagbha/a,
metallic preparations had begun slowly to
creep into use, and at the time of Chakrapawi
and his predecessor Vrmda, they had so
fully established their claims that they could
no longer be ignored. Thus we find from
the tenth century and downward every

medical work more or less recommending
compounds of metals which can only be
synthetically prepared.
It should not, however, be forgotten that
Su^ruta at times shows a knowledge of
pharmacy, unsurpassed in the later Hindu
medicine.
Although Chakrapa;/i belonged to the
Biâhmanical creed, his writings show a
decided leaning towards Buddhism. Thus
Maghadha itself is ' named iT^T^Vf^JTI^^ or
the country of the Mahabodhi ; we have also
such expressions as ^ftf^^^fWlfir??, îfT^^
^f%, ^^^FTiT^^ f This might well be expect-
ed, for Chakrapa/î's father was physician
to king Nayapala, the successor of Mahipala,
who ascended the throne about 1040 A.D.-
(i) The author, fortunately for future historians, has given

an account of himself in a colophon :

Ivi
Both VWiida and Chakrapawi mention Nag-
arjuna as an Authority, and they follow closely
in the footsteps of Charaka, Su^ruta arid
Vagbha/a ; but at the same time they are
amenable to the influences brought to bear
upon medicine by the Tantras.
Indeed, they go so far as to recommend
the uttering of the cabalistic interjections of
the votaries of the Tantric cult with a view
to increase the efficacy of some of their pre-
parations/ (see ante p. i.)
Dr. Hoernle observes : *'it would be satis-
factory to be able to discover what

the sources were on which Chakrapawi
drew for his compilation ; they are not speci-
fied anywhere, I beHeve, in his work. '' ^ It
is not easy to account for the above remarks,
seeing that Chakrapa/zi distinctly mentions
that he has modelled his work on the Siddha-
yoga of VWnda, ^ and that he draws largely
upon the Charaka, the Su^ruta and the
Vagbha/a, all of whom he quotes verbatim
and at length.
The religion of ^Sakyamuni inculcates the
alleviation of distress and suffering, both
moral and physical, as one of the essential
articles of faith, and hence we find throughout

Buddhistic India hospitals attached to the
numerous monasteries for the treatment of
man and beast alike. ' It would also appear
that inscriptions were engraved on rock pillars
giving recipes for the treatment of diseases.
Thus both VWnda and Chakrapawi speak of
a formula for a collyrium as inscribed on a
stone pillar by Nagarjuna at Pataliputra :
Chakrapf.wi bases his work on that of

It necessariy follows that Vrmda was a

** The Hindus do not pay particuh.r attention to
alchemy, but no nation is entirely free from it, and
one nation has more bias for it than f nother, which
must not be construed as proving iitelligence or
ignorance ; for we find that many inte ll;gent people
are entirely given to alchemy, wl ilst ignorant
people ridicule the art and its adepts. Those intel-
ligent people, though exulting boisterously over
their make-believe science, are not to be blamed
for occupying themselves with alch<*my, for their
motive is simply excessive eagerness for acquiring
fortune and for avoiding misfortune. Once a sage
was asked why scholars always flock to the doors
of the rich, whilst the rich are not inclined to call
at the doors of scholars. * The scholars/ he
Ix
answered, *are well aware of the use of money, but

the rich are ignorant of the nobility of science/
On the other hand, ignorant people are not to be
praised, although they behave quite quietly, simply
because they abstain from alchemy, for their motives
are objectionable ones, rather practical result of
innate ignorance and stupidity than anything else.
" The adepts in this art try to keep, it concealed,
and shrink back from intercourse with those who
do not belong to them. Therefore, I have not
been able to learn from the Hindus which methods
they follow in this science and what element they
principally use, whether a mineral or an animal or a
vegetable one. I only heard them speaking of
the process of sublimation, of calcination^ of analy-
sis, and of the waxing of talc^ which they call
in their language ^'talaka,*' and so I guess that they
incline towards the minerological method* of
alchemy.
*! They have a science similar to alchemy which
is quite peculiar to them. They call it Rasdyana^

an art which is restricted to certain operations,
drugs, and compound medicines, most of .which

health of those who were ill beyond hope,
and give back youth to fading old age, so that
people become again what they were in the age
near puberty ; white hair becomes black again, the
keenness of the senses is restored as well as the
capacity forjuvenile agility, and even for cohabita-
tion, and the life of the people in this world is
even extended to a long period. And why not ?
Have we not already mentioned on the authority
of Patafijali that one of the methods leading to
liberation is Rasayana? AVhat man would hear
this, being inclined to take it for truth, and
not dart off into foolish joy and not honour
the master of such a wonderful art by popping
the choicest bit of this meal into his mouth?"

The Tantrlo Period

Circa iioo A.D, ijoo A.D.
Before we proceed further it would be
advisable to take a hasty
tdcTy^ '^^ ^^"" glance at the origin of the
Tantric Cult, as Indian Al-
chemy very largely derives its colour and
flavour from it. In almost every country
the progress of chemistry can be traced
to medicine and the belief in the artificial
gold-making, the search after elixir vitce
and the philosopher's stone. In India,
however, these ends have played a secondary
part in promoting a knowledge of the chemi-
cal processes. Here the origin of astronomy,
geometry and anatomy is to be sought in
the exigencies of religious rites. ^ No less
(i) Cf. the opening remarks by Dr. Thibaut on the " Sulva-
sutras " ;
Ixiii
is the case with alchemy. We have alrieady'

seen how the Atharva-veda deals almost
exclusively in charms, sorcery, exorcism of
diseases by means of amulets and so on.
It is sometimes supposed that the A.V.
represents the latest of the Vedas. This
is evidently a misimpression. ' The truth
seems to be that human frailty has always
fought shy of the tedious and laborious
methods of gaining an object. The spiritual
hankering as foreshadowed in the prayers
of the Iîky and later on so fully developed
" It is well kuown that not only Indian life with all it's social
and political institutions has been at all times under the mighty
sway of religion, but that we are also led back to religious belief
and worship when we try to account for the origin of research in
those departments of knowledge which the Indians have cultivated
with such remarkable success. At first sight, few traces of this
origin may be visible in the 5astras of the later times, but looking
closer we may always discern the connecting thread." "Journ.
As. Soc." (1875) Vol. XLIV. part i. p. 227.
(i) As Bloomfield remarks : There is no proof that even
the oldest parts of the R. V. or the most ancient Hindu tradition
accessible historically, exclude the existence of the class of writings,
entitled to any of the names given to the Atharvan charms.'
Intro, to A. V. X. pXX.
Ixlv
in the Upanishads, represents only the

aspirations of the few cultured /?zshis. The
bulk of the people have always sighed for
a royal road to salvation, hence the neces-
sity for an A.V. ; as Emerson appositely
says in his essay on Demonology, ''the
history of man is a series of conspiracies
to win from Nature some advantage without
paying for it/* Atharvanic rites have there-
fore more or less held sway over man-
kind in every age and clime. As the Aryan
conquerors began to settle in India and
came into frequent contact with the abori-
gines, they had unconsciously to imbibe
some of the gross superstitions of the latter,
and thus in course of time a superstructure
of monstrous growth sprang up, ready to
swallow even the purer and more othodox
creed. Hence the protests recorded from
time to time in the Mahabharata and in
the law-books against the vulgarity of the
aims of the A. V. and the refusal to accept
its authority (see ante p. viii). But on the
other hand, by virtue of its profound hold
Ixv
upon popular beliefs and because indispen-
sable sciences like medicine and astrology
are Atharvanic by distiction, the fourth
Veda has always retained a considerable
following. ^ If we turn to Europe in the
middle ages, we find the professors of the
" black art '' sharing a fate similar to the
priests of the Atharvanic rites, ^now
openly received into the bosom of the holy
church now anathematised and flung
into prison. ^
In the Sanskrit Literature whenever there
is any reference to sorcery or magic, it is
generally laid to the account of the A. V.
But in the course of time the worship of
5'iva came into vogue, which incorporated
much that was non-Aryan in character, and
which seems to have got blended with A. V.
(i) Bloomfield : Intro, to A. V. xlvi.
(2) This is exemplified in Albertus Magnus and Roger Bacon.
The former rose to be a Bishop but " minder glucklich oder un-
vorsichtiger als Albertus Magnus, entging Roger Baco der Verfol-

rites as modified by changes and require-
ments of the time. The original inhabitants,
" the Dasyus are described in the /?igveda
as non-sacrificing, unbeHeving and impious.
They are also doubtless meant by the phal-
lus-worshippers mentioned in two passages.
The Aryans in course of time came to adopt
this form of cult. There are many passages
in the Mahabharata showing that SWa. was
already venerated under the emblem of the
phallus when that epic was composed.'' '
By the Vllth century A. D., we find
^ diva's worship well established
Tantric rites
prevalent in the m India. In the life of King
Harsa by Vaa there is a gra-
phic description of a weird ceremony performed
by a Saiva, saint named Bhairavacharyya.
** Seated on the breast of a corpse which lay
supine, anointed with red sandal and arrayed
in garlands, clothes and ornaments, all of red,
himself with a black turban, black unguents,
black amulet, and black garments, he had
(i) Macdonell": "Hist. Sansk. Lit*', p. 153.
Ixvii
begun a fire rite in the corpse's mouth where

a flame was burning." ^ In the drama of
Malatimadhava by Bhavabhiiti (690 A.D.) we
have also references to similar rites.
We have here the outlines of what has been
known latterly as the Tantric Cult a curious
admixture of alchemical processes on the one
hand, and grotesque and obscene and some-
times revolting rites on the other all centred
round the worship of 5'iva and his consort
Parvati. The sidelight which is thrown in the
life of King Harsa and the graphic account
left by his contemporary, the Chinese pilgrim
Hiuen Thsang, enable us to draw a picture of
N. India in the Vllth century A. D, It has
hitherto been taken almost for granted that
Buddhism was expelled from India by the
persecution of the Brahmins of the Renais-
sance period. There may have been zealous
bigots who now and then went the length of
hunting down Buddhists ; but the concensus
of testimonies seems to be that both the

people and the princes generally maintained
an attitude of philosophic toleration towards
the creed of Sakyamuni even so late as the
Xlth century A.D.* The causes which

The causes which India workcd from within,

Ci) Cf. 'The annual report of the Asiatic Soc. to hand :
"The copper-plate of Madanapala which has just been
referred to is interesting also from a sociological point of view.
We know that all the Pala kings were followers of the Buddhist
religion, and that it was during their reign that Buddhism flouri-
shed for the last time in India. Now the grant recorded in the
plate was made by Madanapala to a Brahman as a dakshina or
honorarium for having read the Mahabharata to the queens of the
king's harem. This is one more fact, in addition to others pre-
viously known, showing the intimate connexion that existed in
the time of those Buddhist kings between Buddhism and Hindu-
ism, a connexion that resulted in the former losing more and
more its ground against the latter, and that thus prepared the
way for the final destruction of Buddhism by the Muhammedan
invadors.'* p. 26. Similar evidence is also afforded by Raj. Tar. e.g.
"Kalhana does not hesitate to refer repeatedly to the Bodhi-
sattvas or to Buddha himself as the comforters of all beings, the
embodiments of perfect charity and nobility of feeling. They are"
to him beings of absolute goodness "who do not feel anger eveft
Ixix
The monasteries degenerated into hot beds of
corruption, so much so that the semi-savage
Mussulman conquerors felt little compunction
in putting: the inmates thereof

to the sword. ' Hinduism also
which has been noted in all ages for its as-
similative and elastic character, swallowed up
the remnants of the Buddhists by acknowledg-
ing the founder of their religion to be an
Avatdra or Incarnation of Vishwu.
We have seen that the A.V. rites as also
theTantric cults cover almost identical ground;
both had their origin in the attempts at
popularising the religion among the masses
by appealing to the baser or the less refined
elements of human nature. An enormous
bulky literature has thus sprung up represen-
ting this corrupt and effete outgrowth of
against the sinner, but in patience render him kindness.,, Stein's

Brahminism.' There are however two distinct
classes of Tantras Brahminic and Buddhis-
Tantras Brah- tic dcaHng in magic, alchemy,
minic and Bud- ^ ii* i i
dhistic sorcery, and allied subjects,
which will claim our attention here. The causes
which favoured the rise and progress of the
Hindu Tantras equally contributed to the
development of the Buddhistic, " only in
the latter, instead of i'iva and Parvati,
a Buddha, a Tathagata or an Avalokitesvara
is often addressed in the invocation as the
source and fountain of all knowledge. We
have also a class of Tantras which is an ad-
mixture of Buddhistic and âiva cult. A
notable example of which is afforded by the
(i) Tantras grew up in Kismfr also : "Tantric cult which in
Ka^mfr is still closely connected with 5aiva worship, seems also
to have been well known to Kalhawa." Stein's Intro, to Raj. Tar
p. 80.
(2) Cf. "Pour des esprits grossiers et ignorants, de tels
livres ont certainement plus de valeur que les Mgendes morales
des premiers temps du Buddhisme. lis promettent des avantages
temporels et imm^diats ; ils satisfont en fin k ce besoin de

Ixxi
Mahakala Tantra. ^ Rasaratnakara, the

authorship of which is ascribed to Nagarjuna,
also belongs to this category ; this work as
well as Rasar//ava, a Tantra of the i'aiva cult,
will claim our special attention, as they
embody much valuable information on
chemistry.
What is it that made these Tantras the
repositories of chemical knowledge ? The
answer is given in the words of Rasar/âva (lit.
sea of mercury) itself, which extols the virtues
of mercury and its various preparations :
** Asitis used by the best devotees for the highest
end, it is called par ada (quicksilver).**
" Begotten of my limbs, it is, O goddess, equal
to me. It is called rasa because it is the exudation
of my body."
*' It may be urged that the literal interpretation
of these words is incorrect^ the liberation in this
life being explicable in another manner. This
"Intro a I'hist. du Buddhisme Ind." p. 466. Regarding Buddhistic
Tantras and their relationship to 5aiva Tantras, the reader is
referred to Burnouf's admirable exposition (loc. cit). See also
Barth's. ** Religions of India." p. 201,. 3rd ed.
(i) Intro. Hist. Buddh. Ind., p. 480.
Ixxii
objection is not allowable, liberation being set out

in the six systems as subsequent to the death of the
body, and upon this there can be no reliance, and
consequently no activity to attain to it free from
misgivings. This is also laid down in the same
treatise.
^* Liberation is declared in the six systems to
follow the death of the body."
^* Such liberation is not cognised in perception
like an emblic myrobalan fruit in hand.*'
'*^ Therefore a man should preserve that body
by means of mercury and of medicaments. *'
A few more typical extracts are given below
which will throw further light on the subject :
" The body, some one may say, is seen to be
perishable, how can then its permanency be effected?
Think not so, it is replied, for though the body, as a
complexus of six sheaths or wrappers of the soul,
is dissoluble, yet the body as created by Hara and
Gauri under the names of mercury and mica, may
be perdurable. Thus it is said in the Rasahr/daya :
** Those who without quitting their bodies have
attained to new ones through the influence of Hara
and Gouri (mercury and mica), are to be praised as
Rasasiddha (alchemists). All mantras are at their
services."
Ixxtii
*' The ascetic, therefore, who ^spites t6
liberation in this life, should first itiakle to
himself a glorified body. And inasmuch as
mercury is produced by the creative con-
junction of Hara' arid Gauri, and mica is
produced from Gauri, mercury and mica are
severally identified with Hara and Gauri in
the verse :
* Mica is thy seed, and mercury is my seed ;
" The combination of the two, O goddess, is
destructive of death and poverty."
''There is very little to say about the
matter. In the Rase^varasiddhanta nfiany
among the gods, the Daityas, the Munis'
and mankind, are declared to have attained
to liberation in this life by acquiring a divine
body through the efficacy of quicksilvel".''
" Certain gods, Maheâ and others ; certain
Daityas, Kavya (Sukrachatya), and others ; certain
sages, BalakhilyaS and others ; certain kings,
Somesvara and others ; Govinda-Bhagavat, Govin-
danayaka, Charvari,'*Kapila, Vyali and others '
these alchemists, having attained to mercurial bodies
and therewith identified are liberated though alive."
'The itieaning of this, as unfolded by
5iva to Parvati, is as follows i-^
''Tke preservjttion of body, O Supreme goddess!
is obtained by mercury and by (the suppses^n etC)
breath. ^ Mercury, when swooned, cures diseases
and when killed, restores life to the dead. Mercury

One very strong argument in favour of
much older dates of the above Tantras is,
that Madhavacharya) a very cautious and

torical evidence is of great use to u lii
deciding the age of the Tantras, dealing with
mercury.
Contemporary collateral records by
foreign writers go to corroborate the date of
the alchemical Tantras tentatively fixed by
us, as the name and fame of mercurial re-
medies as used by the Hindu yogis had
spread far and wide. The following two
extracts will suffice :
'^There is another class of people called Chughi

reader will put up with infelicities of

he avoided without taking undue liberty with
the original. We have drawn very largely
upon R. R. S:, because it has several features
to recommend. First, an excellent edition of
it has been published at Puna, based upon a
comparison of 13 Mss., procured from dif-
ferent parts of Southern India. Second,
there exists a Ms. of it in the librarv of the
Sanskiit College, Benares, in a very neat and
Ixxxvi
legible handwriting, copied in samvat 1850
i. e. 1793 A.D., to which we have had access
whenever required. We have also obtained
a transcript of it from the KLymir Library.
The Benares and the Ka^mir Mss. agree in
all essentials, but differ in certain places fronfi
the Puna edition. The text we have adopt-
ed is thus based upon a comparison 6f the
Deccanese and N. Indian 6xeftiplars. Third,
while Rasaratnakara and Rasarwava are Tan-
tras pure and simple in which alchemy i^ inci-
dentally dwelt upon, R. R. S. is a systematic
and comprehensive treatise on materia itietfi-
ca, pharmacy and medicine. Its methodical
and scientific arrangement of the subject-
matter would do credit to any rafodern work,
and altogether it should bfe proftoiinced a
production unique of its kind ifi Sanskrit lite-
rature. Its value is further enhanced from
the lact that the materia medica portion is
harmoniously blended with chemistry.

CBAiFTER V
latrrChamleal Period
During the Tantric period, with its sys-
tem of the ^'Philosophy of
Characterstics of ^ r^ r
the intro-chemicai Mercury'' a vast mass of che-
period. . , / <
mical information was accu-
mulated, which was pressed into signal ser-
vice in the period immidiately succeeding it
the latro-chemical Period of India. The
prominent feature of the former lies in the
search after the elixh- vttae and the pow^der
of projection as the contents of the Rasa-
ratnakara and Rasarwava amply testify;
whereas in the latter these phantastic and ex-
travagant ideas, impossible of realisation, had
subsided into something more practical and
tangible. The numerous preparations of
mercurv, iron, copper and other metals, al-
though they could not secure immortality or
revive the dead, were found to be helpful
accessories in medicine. At first they came
XCl
to be used cautiously and tentatively, mixed

up with the recipes of the Charaka and the
Su^ruta, which are drawn chiefly from the
vegetable kingdom ; but they soon began to
assert a supremacy of their own and even to
supplant the old Ayurvedic treatment by
herbs and simples. Nay more, absurd, pre-
tentions were set up on behalf of these metal-
lic preparations. Thus in Rasendrachinta-
mawi, a work probably co-eval with R. R. S.,
we' come across this remarkable passage :
'^Revered teacher 1 be pleased to instruct me,
for the benefit of the weak and the timid, in
a mode of treatment which will dispense with
the use of the lancet, and both active and
potential cauteries," thus putting in a plea
for the indiscriminate use of mercurial
remedies.
R. R. S. is a typical production of the
latro-chemical period. The name of treatises
treating of medicinal chemistry is simply
legion. But they are all cast in the same
mould, and the close similarity of their con-
tents would render their translation only a
xcu.
works of supererogation. We have, there-

fore, confined ourselves to quoting only such
parallel passages ia the foot-notes as are
calculated to throw light upon or corroborate
the authenticity of, the text of R. R. S.
An account of this period will be scarcely
complete, which fails to take
note or the conspicuous hguth
whom the Indian alchemists unanimously
look upon as the inventor of the processes
of distillation and calcination the renowned
and the venerable Nagarjuna, the reputed
author of Kakshaputatantra, Rasaratnakara
and Arogyamanjari, etc. Our R. R. S., in
the opening lines, invokes him as one of the
27 alchemists, and in the chapter on minerals
quotes him as an authority. So does Rasen-
drachintamawi as also Chakrapawi while des-
cribing the process of roasting iron (p. 62).
We have already seen that according to
Vrmda and C. p., Nagarjuna was the first to
introduce the preparation known as Kajjvali
(black sulphide of mercury p. 61). Dalvawa
also makes him the redactor of the Su^ruta.
xcin
The mention of Nagarjuna by all these author-
ities would not remove him far from the 8th
or the 9th century A. D., a date which is
also confirmed by Alberiini, who says :
"A famous representative of this art
[alchemy] was Nagarjuna, a native of the
fort Daihak, near Somnath. He excelled in
it and composed a book which contains the
substance of the whole literature on this
subject and is very rare. He lived nearly a
hundred years before our time/ 'India, I. p.
189. .
But there are difficulties in the way of
accepting this chronolgy of the age of Na-
garjuna. Hiouen Thsang, who resided in
India from 629 A. D. onwards, relying upon
local traditions, i^peaks of Nagarjuna ^ as a
(l) *' Nagarjuno Bodhisatva was well practised in the art of
compounding medicines; by taking a preparation (pill or cake)*
he nourished the years of life for many hundreds of years, so that
neither the mind nor appearance decayed. Satvaha-raja had par**
taken of this mysterious medicine."^Bears Buddhist Records of
the Western World, vol. II. p. 212. .
Again : Then " Nagarjuna Bodhisatva, by moistening all the
great stones with a divine and superior decoction (medicine or
mixture) changed them into gold.'' Ihid, p. 216.

learned and revered Buddhist and alchemist,

and a. friend of King Satyahana. '^ The poet
Vaa, a contemporary of the Chinese pilgrim,
also corroborates this account in his life of
King Harsha.
In the Buddhist canonical literature, Na-
garjuna is a prominent figure, as the founder, or,
atanyrate,thesystematiser of the Madhyamika
philosophy. Western scholars maintain that he
lived in the ist century A.D., while according
to Rajatarangini, the ''History of Ka^mir'' by
KalhaA/a Miâ (i i century A. D.), Nagarjuna
flourished 1 50 years after Sakyasiwha had be-
taken himself to asceticism, i.e. he lived in
the last quarter of the 4th and first quarter
of the 3rd century B. C. It is doubtful,
however, if Nagarjuna, the philosopher, is the
same as Nagarjuna, the alchemist, considering

that we find no reference whatever to the pro-
cesses of distillation, sublimation etc. in the
Charaka, the Su^ruta, and the Vagbha/a,
though it must be admitted that the latter
can lay claim to superior chemical knowledge,
(see p. xlviii),.

Sivadasa, in his commentary of Ghakrapam,

of Patanjali, as a physician both to the mind
and to the body. ^ The moksha (salvation),

already seen, while discussing the "Philosophy

or Alchemy was simply regarded as a means
to an end as a path leading to moksha. It
is significant that this connection can be
traced from so early a date.

will, perhaps, add to the
interest of the subject, if we turn our eyes for
a moment to the progress of chemical know-

mistic ideas .and beliefs dominating it. Con-
temporary with the authors of Rasar/âva and
Rasartnasamuchchaya, were Roger Bacon

the Hindu alchemists . and their European
confreres.

'diagnostic test of metals was well under-
stood (p. 68). The metallurgical processes,
described under the latter, leave little to
.improve upon (p. 88), and, indeed, they
may be transferred bodily to any treatise on
modern chemistry. Even Paracelsus, who
i flourished some three centuries later, leaves
"US in the dark as to the nature of his 'zinken,'
which he designates a *semi* or * 'bastard'
metal. And Libavius (d. 1616) **who stood
:up manfully against the excesses of Paracel-
sus, and who vigourously combated the de-
fects in his doctrines, * * * -ind the
employment of *' secret remedies,'^ believed in
the transmutation of the metals and the ef-
ficacy of potable gold.' It is not necessary
to pursue this subject further here, as details
will be found in the chapter on metallurgy
(pp. 152-169).
The truth is that up till the time to
pseudo-Basil Valentine (ca. 1600 A. D.),

very little scientific ' progress was adiieved 1
in Europe. The doctrines of Aristdtle '^ftdq

\vhich was often used as a * cloak fpf igfiOf '

pharmacy: For two thousand years dr mpre^
the Charaka and the Su^ruta have bên pîd
all the honours of a state-recognised Phar- :

as of revealed origin, and partly due to that:
veneration for the past, which is ifiherent in-
the Hindu, the text of the above wOrks h^fe;
seldom been allowed to b^ tampered with.'
A critical examination of the Bower Ms. such '
as- we owe to Dr. Hoernle, shows that the
recipes of several important preparations
agree in all essentials, and sometimes word '
for word, with, those of the Charaka and the
Susruta of the existing recensions (see ante <
p. xix). Mr. Ameer Ali is scarcely correct
when he claims that '* the Arabs invented
chemical pharmacy, and were the founders of
those institutions which are now called dis-

pensaries.' '
We have only to refer our reader to the
chapter on the preparation of caustic alkali,
in the Suûta, with the direction that the
strong lye is to be " preserved in an iron
vessel/' as a proof of the high degree of per-
fection in scientific pharmacy achieved by
the Hindus at an early age (p- 37). It is
absolutely free from any trace of quackery
or charlatanism, and is a decided improve-
ment upon the process described by a Greek
writer of the IXth century, as unearthed by
M. Berthelot.* As regards dispensaries and
hospitals, every one knows that Budhistic
India wa'^ studded with them {vide p. xxxii).
Speaking of the progress of chemistry in
Europe in the XVIth century, Prof. Schor-
lemmer remarks :
"Up to the XVIth century almost the sole
object of chemical research had been to find the

philosopher's stone. But now chemistry began to

develop itself two new and different paths, opened
by two distinguished men Agricola, the father of
metallurgy, and Paracelsus, the founder of latro-
chemistry or medical chemistry. Both contributed
chiefly to the development of inorganic chemistry
* * * In opposition to the school of Galen and
Auicenna, Paracelsus and his followers chiefly em-
ployed metallic preparations as medicines." *
Udoy Chand Dutt, in the preface to his
Materia Medtca of the Hindus, states :
**The oldest work, containing a detailed ac-
count of the calcination or preparation of the
different ipetals (such as gold, silver, iron, mercury,
copper, tin and lead) for internal use with formulae
for their administration, is, I believe, a concise
treatise on medicinal preparations by Sarngadhara.
This is evidently a mistake. Sarngadhara
is simply a compilation based upon the Char-
aka and the Su^ruta on the one. hand, and
the Tantric works described above on the
other. It cannot be regarded as going be-
yond the latter part of the 14th century, and

it will come under our notice in the second
volume of the present work. In the European
histories of chemistry, the credit of being the
first to press chemical knowledge into the
service of medicine and introduce the use of
the internal administration of mercurial pre-
parations, is given to Paracelsus (1493-1541)
The Nagarjunas and the Patanjalls of India,
however, had the merit of anticipating Para-
celsus and his followers by several cenfuries-
The earliest historical record of the internal
use of black sulphide of mercury dates so far
back as the loth century A. D. at the latest*
(see ante p. 59). We have indeed, reasons
to suspect that Paracelsus got his ideas from
the East, and in Chapter on Arabian indebt-
edness to India we have pointed out the
media through which Indian sciences filtered
into Europe.

Dutt says : ^'.We cannot. help admiring the in-

genuity and the boldness of the Hindu physicians,
when we find that they were freely aud properljr
using such powerful drugs as x arsenic, mercury,
iron, etc., when the Mussulman Halîms arpund
them with imperial, patronage and the boasted
learning of the West, recording such remarks re-
garding them as the following :
*' Soomboolkhar, Hhe white oxide of arsenic. '
There are six kinds of this, one name Sunkia, the
third Godanta, the fourth Darma, the fifth Huldea.
The Yunani physicians do not allow this to form
a part of their prescriptions, as they believe it des-
troys, the vital principle. The physicians of Ipdia,
on the contrary, find these drugs more effectual in
many disorders than others of less power such as
the calx of metals. For this reason too I am in
the habit of seldom giving these remedies inter-
nally, but 1 usuatly confine my use of them to ex;-
ternal application and as aphrodisiacs which I
prescribe to a few friends, who may have derived
no benefit from Yunani prescriptions. It is better
to use as few of them as possible.'* ^

Apart from the historical data already ad-
duced, the above extracts from a Mohamme-
dan writer would show that the Hindus were
perhaps the earliest in the field to advocate
the internal use of mercury.^ Ainslie, in a
note appended " Lepra Arabum,'' written in
the early part of the last century, thus ex-
presses his views on the subject :

note appended to^^ Lepra Arabum/' written in

the early part of the last century thus ex-
presses his views on the subject : -
** It is well known that the Eastern nations were
the first who employed mercury in the cure of
obstinate, cutaneous and leprous affections ; and it
may be questioned whether the natives of India
were before the Arabian or only second in order
in availing themselves of the virtues of that power-
ful mineral. Rhases, * Mesu and Avicenna * all
notice it, and according to Fallopius, as we find
observed by Le Clerc in his "Histoire de la M^di-
cine'* pp. 771-791, it was the opinions of those
writers which first suggested its use in venereal
diseases. '
(i) " Argentum vivum cum extinguitur ardens est, quod

scabei, et pediculis auxilium offert " Rhazes :" de Re med." (lib iii.
cap. xxiv). In the days of Pliny the Elder the medicinal virtues
of mercury do not appear to have been at all ascertained ; that
writer termed quicksilver the bane and poison of all things and
what would with more propriety be called death silver. "Nat.
Hist." lib xxxiii. Cap. vi).
(2) Avicenna says of mercury " argentum vivum extinctum
ad versus pediculos et lendes cum rosaseo oleo valet.'' Vide
. '' lib. ii. tract, ii. p. 119.

CVl
From the evidences we have adduced all

along there can now be scarcely any question
as regards the priority of the Hindus in mak-
ing mercurial remedies a speciality; and they
are entitled to claim originality in respect of
the internal administration of metals generally
seeing that the Charaka and the Su^ruta, not
to speak of the later Tantras, are eloquent
over their virtues.
TI.
Inilebtedness of the Arabians to India.

The Arabians are acknowledged on all
hands to have played a prominent part in the
propagation of science and mathematics in
the West. When in the dark and middle
ages, the lamp of knowledge had begun to
burn very low in Europe and even when the
very vestiges of Greek culture and learning
had all but disappeared, save in the obscure
and dingy cells of the monk, it was the Arabs
who carried there the accumulated intel-
lectual treasures of the East, and thus laid
the foundation, so to speak, of modern Euro-
pean greatness.
It will, perhaps, be not out of place to dis-
cuss here briefly as to how much India in-
directly contributed to this result in the de-
partments of medicine, pharmacy and other
kindred subjects.
CVlll
The author of Kitab-al-Fihrist ^ who wrote

towards, the middle of the tenth century',
Haji Khalifa and Ibn Abii Usaibiah, who
flourished at the commencement of the 13th
century, distinctly mention that by order of
the Caliphs Harun and Mansur several stand-
ard Hindu works on medicine, materia medica
and therapeutics were translated into Arabic.
The information on the subject has been gather-
ed at length by Dietz in his Analecta medica,
Wustenfeld, author of Geschichte der Arab,
Aerzte, Cureton*, Fliigel, Miiller and other
Arabic scholars.
(i) " Abu'I Faraj Mohammed bin Ishak, surnamed au-
Nadim, a native of Bagdad, first conceived the idea of a biblio-
graphical dictionary. His Kitab-al-Fihrist deals with evêry
branch of learning. It gives the names of many authors and
their works which have ceased to exist." Hist, of the Saracens
by Ameer Ali, p. 469.)
(2) Prof. H. H. Wilson in a Note appended to a paper by
the Rev, W. Cureton entitled " A collection of such passages
relative to India as may occur in Arabic writers" thus pithily
summarises his own views : '' In medicine the evidence is more
positive, and it is clear that that the Charaka, the Susruta,
the treatise called Niddna on diagnosis, and others on poisons,
diseases of women and therapeutics, all familiar to Hindu Science,
were translated and studied by the Arabs in the days of
CIX
Fliigel^ states on the authority of Kitab-al-

Fihrist that Susrud (the Sanskrit name
Su^ruta, thus corrupted into Arabic) was
translated by Mankh, the Indian, who cured
Harun ar-Raschid of a severe illness, and
was appointed physician in charge of the
Royal Hospital. We also learn that a work
on the official plants of India was rendered
into Arabic by the same Mankh. The other
comprehensive Sanskrit treatise, the Charaka
was also fully laid under contribution.
We have ample and overwhelming testi-
mony of Arabic writers, notably of Haji Kha-
lifa, that Hindu astronomy, algebra and
medicine were zealously studied by their com-
patriots, and many Hindu servants were in-
duced to reside at the Court of the Caliphs
as their instructors. Mussulman students,
Harun and Mausur, either from the originals or translations, made
at a still earlier period, into the language of Persia." Journ.
Royal Asiatic Soc. old series, vi. pp. 105-115.

in their eager thirst for knowledge, used to
flock to the centres of learning in India, and
there drank deep at the very fountain-head.
Indeed, it had come to be regarded as an
essential part of completing one's liberal
education to travel to India and learn the
sciences firsthand*
That this is no language of rhetoric will be
evident from the extracts quoted below from
Gildemeister's '* Scriptorum Arabum De
Rebus Indicis loci et opuscula/'
" Etiam Muhammed ben Ismail al Tanukhi in

Haas, whose criticism of the Su^riita we
Muiier's refuta âve already noticed, having
tion of Haas. once /taken up the position
of denying the antiquity of Hindu medicine
with special regard to the Charaka and the
Su^ruta, was driven to the necessity of dis-
counting, nay, explaining away, the numerous
references to Hindu works made by Mussul-
man writers. This had the effect of eliciting
a reply from Miiller, who subjected the
Arabic literature bearing on the subject to a
CXll
crucial examination, especially Book XII of

Useibia. He finds that not only the Charaka
and the Su^ruta, but also the Nidana and
the compendium As4nkar/ a book on Poison
by Sanaq the Indian, and another on Warm
and Cold, and several other works were ren-
dered into Arabic. This German orientalist
also arrives at the conclusion that Indian
physicians practised at the Court of Bagdad.*
We have now to place before the reader the
Aiu^ ' / evidence of a remarkable author
Alberunis evi-
dence. remarkable alike for the depth
of his learning, versatility of his genius, rare
impartiality of his judgment and his singular
freedom from race-bias.
Alberiini lived in India from 1 017-1030
A. D., and during this long sojourn he mas-
tered Sanskrit and studied Hindu mathema-

tics and philosophy in the original. At a

time when his patron, Sultan Mahmud of
Ghzni, was busy pillaging the temples in
Thaneswar, Mathura, Kanauj and Somnath
with the zeal of an iconoclast, this philosophic
Moslem was pondering over the Sa;;^khya
and the Ptitanjala, and instituting a corfipari-
son between their contents and those of the
**Timaeus'^ and its commentator, Proclus.
We have elsewhere quoted at length Albe-
riini's views on Rasriyana (alchemy) ; it now
remains for us to glean such information from
him as will throw light on the subject under
inquiry. According to Sachau, the learned
translator of Alberiini, '' some of the books
that had been translated under the first Ab-
baside Caliphs were extant in the library of
Alberiinf, when he wrote his India, the Brah-
masiddhanta or Sindhind the Charaka
in the edition of Ali Ibn Zain and the Panch-
tantra or Kalila and Dimna.'^ The fact that
the Charaka occupied a place in the library
of a cultured Arab affords an additional proof
of the esteem in which the Hindu system of
CXIV
medicine was held by the Moslem world.

We also learn that *' the Christian philoso-
pher and physician from Bagdad, Abulkahir
Alkhamnour, friend of Alberiini, seems to
have practised in Ghazni his medical profes-
sion" (Sachau). This is significant as indi-
cating that both the Greek and Hindu sys-
tems held sway side by side ; but more of it
anon.^
So far as regards historical evidence. Let
, , , .us now see if any internal evi-
Internal evi- J
dence. deucc could be gathered in cor-
roboration of the former. Reference has
already been made to the Book on Poisons
by Sanaq the Indian. We shall cite here
some parallel passages on the Examihation
of Poisoned Food and Drink. These are
the chief characteristics as given by Sanaq,
the Charaka and the Susruta respectively.
(i) " Dietz also in his A nalecta Medica prpves that the later
Greek physicians were acquainted with the medical Avorks of the
Hindus, and availed themselves of their medicaments ; but he
more particularly shows that the Arabians were familiar with them,
and extolled the healing art, as practised by the Indians, quite as
much as that in use among the Greeks." Royle : " Antiq. Hind.
Med." p. 64.

Miiller has pointed out the parallelism as
shown above. We have, however, added to
it the diagnostic test of poisoned food as
i
CXVl
given In the Charaka, and It will be seen that

SAn&q was equally indebted to this authority
and to the Su^ruta.
The description of leeches as given by
Rases agrees almost word for word with that
of the Su^ruta (Sanasrad) in many places.
SUSRVTA
The variety of leeches called
Krishna is black in colour and
have thick heads, Karvurds
have their bodies, like that of
eels with elevated stripes across
their abdomen. Alagardhds
have hairs on their bodies, large
sides and black mouths,
Indrdyudhds have longitudinal
Mnes along their back, of
^he colour of the rainbow.
Rases, aroTixG Sanasrad
Of the leeches one is poi-

sonous, which is intensely
black like antimony having'
a large head i and scales like
certain fishes and having the
middle green ; also another
upon which are hairs, has a
large head and different
colour like the rain-bow :
Sdmudrikds are of a dark-

yellow colour and have var-
iegated spots on their bodies
resembling flowers in appear-
ance. Gochondands have bi-
furcated tails like the two
horns of a cow and small
heads. When these poison-
CXVll
Otis leeches bite any person,
the bitten parts become swollen
and very itchy, and fainting,
fever, burning' of the body,
vomiting, mental derangement
and langour occur, in these
cases the medicine called Ma-
hdgada should be administer-
ed internally, applied exter-
nally and used as snuff. The
bite of the leech called Indrd-
yudha is fatal. Such is the
dsscription of the poisonous
leeches, and their treatment.
Now the non-poisonous
leeches. Their names are as
follows : Kapild, Pingald,
Sankumukht, MUshikd, Pun,
darikamiikhi and Sdvarikda
in the colour of which there

are lines as in blue-spar,

one which is assimilated to
the colour of water :

Those produced in pure water

They should be kept in a new

plants should be given them for
food. For bedding they should
be furnished with grasses and also when
leaves of water-plants. F'resh they are seized or caught, let
water and food should be them be put away while all
given every second or third that which is in their own
day, and every seventh day belly is being purged : also
the earthen pot should be they ought not to be put on
changed. On the subject except in a place not healthy.
there is the following verse :
Leeches which are very
thin or thick or with their
central portions thick, which
move slowly or do not stick
to the part to which *they are
applied, which drink little
blood, or whicn are poisonous,
are not fit for use. When
about to apply leeches on a
person who has got a disease
curable by them, the patient
should be made to sit or lie
CXXl
down. The afifected part, if

free from pain, should be rub-
bed with a little cowdung and
earth. The leeches should
then be taken hold of and
smeared with a mixture of
turmeric and mustard reduced
to a paste with water. They
should then be placed for a
while in a cup of water^ till
they are relieved of their
weariness and afterwards ap-
plied to the diseased part.
When being applied, their
mouths should be left open
and their bodies covered with
fine white wet rags.
If
they do not bite, a drop of.
milk or blood should be ap-
plied to, or a small incision
may be made on the diseased
part. If even by these means
a leech cannot be applied, it
should be changed for another.
A leech is
known to have fixed itself to
the part when it raises its
shoulder and bends its head
like a. horse-shoe. When
fixed it should be- covered-
also'
anointments ought to be
tnade around the place with
paste that they may not touch
the healthy place : also as
often as leeches are applied, put
over them a fine soaked cloth:'

blood: if it still refuses to
bite, let another be applied

There is thus unmistakable evidence here

of the use of a chapter of the Su^ruta or

That the Charaka should be changed by
Arabic writers into ^^ Sarak/' Su^ruta into
'^Susrud,'^ Nidana into ''Badan/' Astanga into
^'Asankar'' and so forth, need not at all surprise
us. Such transformations can well be ex-
plained on phonetic principles. Moreover^
cxxv
one must re in ember that the Indian works

translated into Arabic were sometimes deriv-
ed from preexisting Phelvi versions, and in
the migrations through successive languages,
the names often got frightfully disfigured. A
notable instance of this kind is afifofded by
the fables of Pilpay (Kalila and Dimna ')
from which La Fontaine borrowed the idea
of several of his fables as he himself acknow-
ledges : ^^ I shall only say, from a sense of
gratitude, that I owe the largest portion of
them to Pilpay, the Indian sage/^ It has
now been made out that Pilpay or Bidpai is
a corrupt form of the Sanskrit word ^Vidyapati'^
(master of learning).
Even long before the time of the Caliphs,
India was the favourite resort of the students
of medicine and other sciences. Thus

the indebtedness of the Arabians to the
Hindus, who contributed not. a little to the

claims of both Greece and India in this res-
pect, when he remarks :
'* The cradle of Arabic literature is not Damas-
cus but Bagdad, the " protection necessary for its
growth being afforded by the Caliphs of the house
of Abbas.
" The foundation of Arabic literature was laid
between 750-850 A.D. The development of a
large literature with numerous ramifications
carried out with foreign materials, as in Rome the
origines of the national literature mostly point to
Greek sources. Greece, Persia and India were
taxed to help the sterility of the Arab mind.'^
We cannot conclude this chapter better
than sum up its substance in the words of
Prof. Sachau :
'^ What India has contributed reached Basfdad
by two different roads. Part has come directly in
translations from the Sanskrit, part has travelled
through Eran, having originally been translated
from Sanskrit ( Pali ? Prakrit ? ) into Persian, and
farther from Persian into Arabic. In this way, e.g\
the fables of Kalila and Dimna have been com-
municated to the Arabs, and a book on medicine,
probably the famous Charaka cf,. " Fihrist, " p. 303.
CXXIX
"In this Gommunication between India and

Bagdad we must not only distinguish between two
different roads, but also between two different
periods.
" As Sindh was under the actual rule of the
Khalif Mansur (A. D. 753-774), there came em-
bassies from that part of India to Bagdad, and
among them scholars, who brought along with
them two books, the ''Brahmasiddhanta** of Brahma-
gupta (Sindhind), and his " Khandakhadyaka "
(Arkand). With the help of these pandits,
Alfazari, perhaps also Yakub Ibn Tarik, translated
them. Both works have been largely used, and
have exercised a great influence. It was on this
occasion that the Arabs first became acquainted
with a scientific system of astronomy. They learned
from Brahmagupta earlier than from Ptolemy.
" Another influx of Hindu learning took place
under Harun, A. D. 786-808. The ministerial
family Barmak, then at the zenith of their power
had come with the ruling dynasty from Balkh,
where an ancestor of theirs had been an official in
the Buddhistic temple Naubehdr i, e. navavihdra,
the new temple (or monastery). The name Barmak
is said to be of Indian descent, mes,ning />aramakaj

used all over the world. The influence which the
decimal system of reckoning dependent on those
figures has had not only on mathematics^ but on the
progress of civilisation in general, can hardly be
over-estimated. During the 8th and gth centuries
the Indians became the teachers in arithmetic and
algebra of the Arabs,, and through them of the
nations of the West. Thus, though we call the
latter science by an Arabic name, it is a gift we
owe to India."
We have thus far attempted to present
our readers with a brief, hurried and neces-
sarily imperfect survey of the gradual evolu-
tion and development of Hindu medicine and
alchemy from the Vedic age onward. We
hope we have been justified in dividing this
entire range into four distinct periods, each
characterised by fairly well defined features.
There are of course no sharp lines of demar-
cation the one imperceptibly merging into
the other. These are (i) The Ayurvedic
Period ; (2) The Transitional period ; (3)
The Tantric period ; (4) The latro-chemical
period.

543. Of course, the Barmak family had been con-

verted, but their contemporaries never thought
much of their profession of Islam, nor regarded it
as genuine. Induced probably by family traditions,
they sent scholars to India, there to study medicine
and pharmacology. Besides, they engaged Hindu
scholars to come to Bagdad, made them the chief
physicians of their hospitals, and ordered them to
translate from Sanskrit into Arabic, books on medi-
cine, pharmacology, toxicology, philosophy, astro-
logy and other subjects. Still in later centuries
Muslim scholars sometimes travelled for the same
purposes as the emissaries of the Barmak, e.g.

The Constitution and Properties of Matter s

the Atomlo Theory
It is not our purpose to discuss in the present
volume the theories dominating Hindu medicine
and, incidentally, chemistry. A concise preli-
minary summary of some of the salient features
of the Sawkhya and Vai^-eshika systems of philo-
sophy is, however, absolutely needed in order to
follow with advantage the excerpts given in this
book from the Charaka, the Su5"ruta and other
works. In connection with this, it would also be
interesting to compare the indebtedness of Hip-
pocrates to the doctrines of Parmenides, Em-
pedocles and other philosophers of the same
school.*

Ka^âda, the founder of the Vaueshika system,
chiefly occupied himself with the study of the pro-
perties of matter. The atomic theory, as pro-
pounded by him, has many points in common
with that of the Greek philosopher Democritus.
His theory of the propagation of sound cannot
fail to excite our wonder and admiration even at
this distant date. No less remarkable is his
statement that light and heat are only different
forms of the same essential substance. But Ka/âda
is anticipated in many material points by Kapila,
the reputed originator of the Sawkhya philosophy.
With the purely metaphysical aspects of these
systems we are not concerned here. Their theories
of matter and its constitution alone fall within the
scope of our present enquiry. We shall now
briefly refer to some of their doctrines.
The Sawkhya, in common with other systems
of Hindu philosophy, teaches that salvation in
after-life is only attainable by perfect knowledge.
According to Kapila, there are three sources of
knowledge which consists in right discrimination
of the perceptible and imperceptible principles

He enumerates these principles to be twenty-five
in number. For our present purpose, however a
few of these only come within our purview. These
wê will present to our readers in the inimitable
language of Colebrooke, whose masterly exposition
of Hindu thought, though written nearly four
scores of years ago, still retains its value and
authoritative stamp ^ :
Tanmatras or Particles.
** Five subtile particles, rudiments, or atoms,
denominated Tanmatras ; perceptible to beings of
a superior order, but unapprehended by the grosser
senses of mankind : derived from the conscious
principle, and themselves productive of the five
grosser elements, earth, water fire, air, and space.

ethereal fluid (akaâ), occupying space : it has the
property of audibleness, being the vehicle of sound,,
derived from the sonorous rudiment or ethereal
atom. 2nd. Air, which is endowed with the pro^
perties of audibleness and tangibility, being sensible
to hearing and touch ; derived from the tangible
rudiment or aerial atom. 3rd. Fire, which is invested
with properties of audibleness, tangibility and
colour ; sensible to hearing, touch and sight r
derived from the colouring rudiment or igneous
atom. 4th. Water, which possesses the properties
of audibleness, tangibility, colour and savour ; beings
sensible to hearing, touch, sight and taste ; derived
from the savoury rudiment or aqueous atom. 5th.
Earth, which unites the properties of audibleness
tangibility, colour, savour and odour ; being sensible
to hearing touch, sight, taste and smell ,* derived
from the odorous rudiment or terrene atom.
Animated Atom.
"The notion of an animated atom seems to be
a compromise between the refined dogma of an
immaterial soul and the difficulty which a gross
.understanding finds in grasping the comprehension
of individual existence, unattached to matter.
HINDU CHEMISTRY
Grosser Body.
"The grosser body, with which a soul clad in
its subtile person is invested for the purpose of
fruition, is composed of the five elements, or of
four, excluding the ethereal, according to some
authorities ; or of one earth alone, according to
others. That grosser body, propagated by gener-
ation, is perishable. The subtile person is more
durable, transmigrating through successive bodies,
which it assumes, as a mimic shifts his disguises
to represent various characters."
We now come to the treatment of the subject by
Ka;2ada in his famous Vaiêshika system. Here
also we are indebted to Colebrooke for the fol-
lowing summary. Kawada arranges the objects of
sense in six categories, viz., substance, quality,
action, community, difference and aggregation.
According to him :
"I. Substance is the intimate cause of an
aggregate effect or product : it is the site of qualities
and of action ; or that in which qualities abide, and
in which action takes place.
"Nine are enumerated, and no more are re-
cognised. Darkness has been alleged by some
HINDU CHEMISTRY
philosophers ; but it is no substance ; nor is body
a distinct one ; nor gold which the Mima/wsakas
affirm to be a peculiar substance.
'Those specified by Kaada are :
Earth.
"i. Earthy which besides qualities common to-
most substances ( as number , quantity, indivi-
duality, conjunction, disjunction, priority, poste-
riority, gravity, fluidity and faculty of velocity^
and of elasticity), has colour, savour, odour and
feel or temperature. Its distinguishing quality is
smell ; and it is succinctly defined as a substance
odorous. In some instances, as in gems, the smell
is latent : but it becomes manifest by calcination.
*'It is eternal, as atoms ; or transient, as aggre-
gates. In either, those characteristic qualities are-
transitory, and are maturative, as affected by light
and heat : for by union with it, whether latent
or manifest, form, colour, taste, smell and tem-
perature are in earth of any sort annulled, and
other colour etc. introduced.
** Aggregates or products are either organised
bodies, or organs of perception, or unorganic masses.-
''Organised earthly bodies are of five sorts.
The organ of smell is terreous. Unorganic masses
HINDU CHEMISTRY
are stones, lumps of clay, etc. The union of
integrant parts is hard, soft or cumulative as
stones, flowers, cotton, etc.
Water.
"2. Water, which has the qualities of earth ;
excepting smell, and with the addition of viscidity.
Odour, when observable in water is adscititious,
arising from mixture of earthy particles.
"The distinguishing quality of water is coolness.
It is accordingly defined as a substance cool to
the feel.
"It it eternal, as atoms ; transient, as aggregates.
The qualities of the first are constant likewise ;
those of the latter inconstant.
"Organic aqueous bodies are beings abiding
in the realm of Varuwa. The organ of taste is
aqueous : witness the saliva. Unorganic waters are
rivers, seas, rain, snow, hail, etc.
"It is by some maintained^ that hail is pure
water rendered solid by the supervention of an
unseen virtue : others imagine its solidity to be
owing to mixture of earthly particles.
Light.
"3. Light is coloured, and illumines other
substances ; and to the feel is hot : which is its
8 HINDU CHEMISTRY
distingliishing quality. It is defined as a substance
hot to the feel. [Heat, then, and light are identi-
fied as one substance.]*
"It has the qualities of earth except smell,
taste, and gravity. It is eternal, as atoms ; not so,
as aggregates.
"Organic luminous bodies are beings abiding in
the solar realm. The visual ray, which is the
organ of sight, is lucid. Unorganic light is
reckoned fourfold : earthy, celestial, alvine and
mineral. Another distinction concerns sight and
feel J as light or heat may be either latent or
manifest, in respect of both sight and feel, or
differently in regard to either. Thus fire is both
seen and felt ; the heat of hot water is felt but
not seen ; moonshine is seen, but not felt ; the
visual ray is neither seen nor felt. Terrestrious
light is that, of which the fuel is earthy, as fire.
Celestial is that of which the fuel is watery, as
lightning and meteors of various sorts. Alvine is that
of which the fuel is both earthy and watery :
it is intestinal, which digests food and drink. Mineral
is that which is found in pits^ as gold. For some
maintain that gold is solid light ; or, at least that
* The sentence under bracket is Colebrooke's own.
HINDU CHEMISTRY
the chief ingredient is light which is rendered solid
by mixture with some particles of earth. Were it
mere earth, it might be calclined by fire strongly
urged. Its light is not latent, but overpowered by
the colour of the earthy particles mixed with
it. In the Mimawsa, however, it is reckoned as a
distinct substance, as before observed. *'^
After giving an account of air and ether etc.,
Colebrooke proceeds with Kawada^s
(i) The term "element " was not generally used in the modern
sense of a component of a compound ; rather it connoted certain pro-
perties characteristic of matter, e.g., coldness, dryness, heaviness,
fluidity etc., thus it referred to certain qualities in the abstract.
The Greek philosophers also held similar, if not identical, views.
Cf. " Empedokles und die moderne Chemie." pp. 185-86 of
** Griechische Denker " by Gomperz vol. i, ed. 1903. The
following extract will also throw much light on the subject :
* The four so-called " elements" air, water, earth and
iire were regarded by that intellectually great philosopher,
Empedocles of Agrigent (about 440 B.C.), as the basis of the world ;
but neither he himself nor Aristotle, who adopted these into
his system of natural philosophy, looked upon them as diiferent
properties carried about by one original matter. Their chief qualities
(the prinuB qualitates oi the later scholastics) he held to be those
apparent to the touch, viz., warm, cold, dry, and moist. Each
of the four so-called elements is characterised by the posses-
sion of two of these properties, air being warm and moist.
xo HINDU CHEMISTRY
Conception of the Simple, Binary, Tertiary,
AND Quaternary Atoms.
" Material substances are by Ka/tada considered
to be primarily atoms ; and secondarily, aggegates.
He maintains the eternity of atoms ; and their
existence and aggregation are explained as
follows :
** The mote, which is seen in a sunbeam, is the
smallest perceptible quantity. Being a substance
and an effect, it must be composed of what is less
than itself ; and this likewise is a substance and
an effect ; for the component part of a substance
that has magnitude must be an effect. This again
must be composed of what is smaller ; and that
smaller thing is an atom. It is simple and uncom-
posed ; else the series would be endless : and,
were it pursued indefinitely, there would be no
difference of magnitude between a mustard seed
water moist and cold, earth cold and dry, and fire dry and
warm. The differences in the material world were, therefore,
to be ascribed to the properties inherent in matter.
* * * *
** Aristotle considered that his four elements were insufficient in
themselves to explain the phenomena of nature ; he therefore
assumed a fifth one, termed ov'via, which he imagined to possess
HINDU CHEMISTRY ii
and a mountain, a gnat and an elephant, each
alike containing an infinity of particles. The
ultimate atom then is simple.
*'The first compound consists of two atoms:
for one does not enter into composition ; and there
is no argument to prove, that more than two-
must, for incohation, be united. The next consists
of three double atoms ; for, if only two were con-
joined, magnitude would hardly ensue since it
must be produced either by size or a number of
patircles : it cannot be their size and, therefore, it
must be their number. Nor is there any reason for
assuming the union of four double atoms, since
three suffice to originate magnitude. The atom
then is reckoned to be the sixth part of a mote
visible in a sunbeam.
*^ Two earthly atoms, concurring by an unseen
peculiar virtue, the creative will of God, or time,
or other competent, cause, constitute a double
atom of earth ; and, by concourse of three binary
atoms, a tertiary atom is produced ; and by
an ethereal or immaterial nature and to permeate the whole
world. As the ^'quinta essentia" this played an immense rdle
among the followers of the Aristotelian doctrine in the Middle
Ages, and gave rise to endless confusion, from the endeavours
of many (who, unlike Aristotle; supposed it to be material) to
isolate it.
12 HINDU CHEMISTRY
concourse of four triple atoms, a quaternary atom ;
and so on, to a gross, grosser, or grossest mass of
earth : thus great earth is produced ; and in like
manner, great water from aqueous atoms ; great
light, from luminous ; and great air, from aerial.
The qualities that belong to the effect are those
which appertained to the integrant part, or
primary particle, as its material cause ; and con-
versely, the qualities which belong to the cause are
found in the effect.
"The dissolution of substances proceeds in-
versely. In the integrant parts of an aggregate
substance resulting from composition, as in the
potsherds of an earthen jar action is induced
by pressure attended with velocity, or by simple
pressure. Disjunction ensues ; whereby the union,
which was the cause of incohation of members,
is annulled ; and the integral substance consisting
of those members, is resolved into its parts,
" There seems to be a high degree of probability in the assump-

tion that Empedocles and Aristotle did not themselves deduce
thfeir theory of the elenrents, but derived it from other sources ;
thus the oldest writings of India teach that the world consists
of the four elements mentioned above, together with ether, which
last is most likely related to Aristotle's <>*vt7ta Meyer's " Hist, of
Chem". Eng. trans, ed. 1898. pp. 7-8. ^
HINDU CHEMISTRY 13
and is destroyed : for it ceases to subsist as a
whole.
Quality of the Substance viz.,
Colour, Savour, etc.
* II. Quality is closely united with substance ;
not, however, as an intimate cause of it, nor consis-
ting in motion ; but common : not a genus, yet
appertaining to one. It is independent of conjunc-
tion and disjunction ; not the cause of them, not
itself endued with qualities.
" Twenty-four are enumerated. Seventeen only
are, indeed, specified in Kaada's aphorisms ; but
the rest are understood.
" I. Colour. It is a peculiar quality to be ap-^
prehended only by sight ; and abides in three
substances ; earth, water, and light. It is a charac-
teristic quality of the last; and,- in that, is
white and resplended. In water it is white,.
but without lustre. In the primary atoms of both
it is perpetual ; in their products, not so. In earth
it is variable ; and seven colours are distinguished :
vijs. white., yellow, green, red, black, tawny (or
orange) and variegated. The varieties of these
seven colours are many, unenumerated. The
six simple colours occur in the atoms of the earth p
14 HINDU CHEMISTRY
^v^*> v^>yK*'.^vy^y
and the seven, including variegated, in its double

atoms, and more complex forms. The colour of
integrant parts is the cause of colour in the
integral substance.
** 2 Savour. It is a peculiar quality, to be
apprehended only by the organ of taste ; and abides
in two substances, earth and water. It is a
characteristic quality of the last ; and in it is sweet.
It is perpetual in atoms of water ; not so in aqueous
products. In earth it is variable, and six sorts
are distinguished : sweet, bitter, pungent, astringent,
acid, and saline.
*'3, Odour. It is a peculiar quality, to be ap-
prehended only by the organ of smell ; and abides
in earth alone, being its distinguishing quality.
In water, odour is adscititious, being induced by
union with earthy particles ; as a clear crystal
appears red by association with a hollyhock, or
other flower of that hue. In air also it is adsciti-
tious : thus a breeze, which has blown over
blossoms, musk, camphor, or other scented subs-
tances, wafts fragrant particles of the blossoms,
tc. The flowers are not torn, nor the musk
diminished ; because the parts are replaced by
a reproductive unseen virtue. However, camphor
and other volatile substances do waste.
HINDU CHEMISTRY 15
Gravitation.
"12. Gravity is the peculiar cause of primary
descent or falling,
*'It affects earth and water. Gold is affected by
this quality, by reason of earth contained in it.
"In the absence of a countervailing cause, as
adhesion, velocity, or some act of volition, descent
results from this quality. Thus a cocoanut is
withheld from falling by adhesion of the foot-
stalk ; but, this impediment ceasing on maturity
of the fruit, it falls.
" According to Udayana Acharya, gravity is
imperceptible, but to be inferred from the act
of falling. Vallabha maintains that it is perceived
in the position of a thing descending to a
lower situation.
Levity.
"Levity is not a distinct quality, but the negation
of gravity.
Fluidity.
"13. Fluidity is the cause of original trickling.
"It affects earth, light and water. It is natural
and essential in water ; adscititious in earth and
i6 HINDU CHEMISTRY
light ; being induced by exhibition of fire in molten
substances, as lac, gold etc.
"Fluidity is perceptible by external senses, sight
and touch.
"In hail and ice, fluidity essentially subsists^
but is obstructed by an impediment arising from
an unseen virtue which renders the water solid.
Viscidity.
14. "Viscidity is the quality of clamminess
and cause of agglutination. It abides in water
only. In oil, liquid butter, etc., it results from the
watery part of those liquids.
Sound.
"15. Sound is a peculiar quality of the ethereal
element, and is to be apprehended by the hearing.
It abides in that element exclusively and is its
characteristic quality. Two sorts are distinguish-
ed : articulate and musical.
Theory of the Propagation of Sound.
"To account for sound originating in one place
being heard in another, it is observed, that sound
is propagated by undulation, wave after wave^
HINDU CHEMISTRY 17
radiating in every direction, from a centre, like
the blossoms of a Nauclea. It is not the first, nor
the intermediate wave, that is the sound heard :
but the last that comes in contact with the organ
of hearing: and therefore it is not quite correct
to say, that a drum has been heard. Sound originates
in conjunction, in disjunction, or in sound itself.
The conjunction of cymbals, or that of a drum and
stick, may serve to exemplify the first. It is the
instrumental cause. The rustling of leaves is an
instance of disjunction being the cause of sound.
In some cases, sound becomes the cause of
sound. In all, the conformity of wind or its
calmness is a concomitant cause : for an adverse
wind obstructs it. The material cause is in every
case the ethereal fluid : and the conjunction of
that with the sonorous subject is a concomitant
cause."
It now only remains for us to furnish a precis
of the atomic theory of Kaada in the words of
Max Miiller:
Anus or Atoms.
" What is thought to be peculiar to Kawada,
nay the distinguishing feature of his philosophy,
is the theory of Aus or Atoms. They take the
2
i8 HINDU CHEMISTRY
place of the Tanmatras in the Samkhya. philosophy.
Though the idea of an atom is not unknown in
the Nyaya-philosophy (Nyaya Sutras, IV. 2, 4-25),
it is nowhere so fully worked out as in the
Vaiêshika. Ka/iada argued that there must be
somewhere a smallest thing that excludes further
analysis. Without this admission, we should have
a regressus ad infinitum^ a most objectionable
process in the eyes of all Indian philosophers.
A mountain, he says, would not be larger than a
mustard seed. These smallest and invisible particles
are held by Kaada to be eternal in themselves^
but non-eternal as aggregates. As aggregates again
they may be organised organs, and inorganic.
Thus the human body is earth organised, the power
of smelling is the earthly organ, stones are
inorganic.
*Ît is, no doubt, very tempting to ascribe a
Greek origin to Kaada's theory of atoms. But
suppose that the atomic theory had really been
borrowed from a Greek source, would it not be
strange that Ka;âda's atoms are supposed never
to assume visible dimensions till there is a com-
bination of three double atoms (Tryawuka),
neither the simple nor the double atoms being-
supposed to be visible by themselves. I do not
HINDU CHEMISTRY 19
remember anything like this in Epicurean authors,
and it seems to me to give quite an independent
character to Kaada's view of the nature of an
atom.
'' We are told that water, in its atomic state, is
eternal, as an aggregate transient. Beings in
the realm of Varuwa (god of the sea) are organ-
ised, taste is the watery organ, rivers are water
inorganic."
"Light in its atomic state is eternal, as an ag-
gregate transient. There are organic luminous
bodies in the sun, sight or the visual ray is the
luminous organ, burning fires are inorganic.
"Air, again^ is both atomic and an aggregate.
Beings of the air, spirits, etc., are organised air ;
touch in the skin is the aerial organ, wind is in-
organic air. Here it would seem as if we had
something not very unlike the doctrine of Empedocles.
* ^ ^ But though we may discover
the same thought in the philosophies of Kaada
and Empedocles, the form which it takes in India
is characteristically different from its Greek form.''*

Dates of the Philosophical Sutras

The Question of Priority.
As regards the dates of the philosophical
sutras, nothing definite is known ; here, as in
the subsequent portions of our history, we have
to depend largely upon constructive chronology.
We quote below two short extracts from Professor
Max Miiller's **Indiaii Philosophy" which sum-
marise all the information available at present on
the subject :
"If we consider the state of philosophical
thought in India such as it is represented to us
in the Brahmaas and Upanishads, and afterwards
in the canonical books of the Buddhists, we
cannot wonder that all attempts at fixing the dates
of the six recognised systems of philosophy, nay
even their mutual relationship, should hitherto
have failed. It is true that Buddhism and Jainism
were likewise but two philosophical systems out of
many, and that it has been possible to fix their
dates. But if in their case we know something
about their dates and their historical development,
this is chiefly due to the social and political import-
ance which they acquired during the fifth, the
HINDU CHEMISTRY 21
fourth, and the third centuries B. C, and not simply
to their philosophical tenets. We know also that
there were many teachers, contemporaries of
Buddha, but they have left no traces in the literary
history of India.
x- ^ ^ ^ *
**We cannot be far wrong therefore if we
assign the gradual formation of the six systems
of philosophy to the period from Buddha (5th
century) to Ayoka (third century), though we have
to admit, particularly in the cases of Vedanta,
Sawkhya and Yoga, a long previous development
reaching back through Upanishads and Brahmaas
to the very hymns of the Rig Veda.
"It is equally difficult to fix the relative posi-
tion of the great systems of philosophy, because,
as I explained before, they quote each other
mutually. With regard to the relation of Bud-
dhism to the six orthodox systems it seems to me
that all we can honestly say is that schools of
philosophy handing down doctrines very similar
to those of our six classical or orthodox systems
are presupposed by the Buddhist Suttas.*' (pp. 116
120)
As regards the question of priority, we shall
also take the liberty to quote below from Prof.
22 HINDU CHEMISTRY
Macdonell's "History of Sanskrit Literature" :
"Turning to Philosophical Literature, we find
that the early Greek and Indian Philosophers
have many points in common. Some of the
leading doctrines of the Eleatics, that God and
the universe are one, that everything existing
in multiplicity has no reality, that thinking and
being are identical, are all to be found in the
philosophy of the Upanishads and the Vedanta
system, which is its outcome. Again, the doctrine
of Empedocles, that nothing can arise which has not
existed before, and that nothing existing can be
annihilated, has its exact parallel in the characteristic
doctrine of the Saw^khya system about the eternity
and indestructibility of matter. According to Greek
tradition, Thales, Empedocles, Anaxagoras, Demo-
critus, and others undertook journeys to Oriental
countries in order to study philosophy. Hence
there is at least the historical possibility of the
Greeks having been influenced by Indian thought
through Persia.
"Whatever may be the truth in the cases just
mentioned, the dependence of Pythagoras on
Indian philosophy and science certainly seems
to have a high degree of probability. Almost all
the doctrines ascribed to him, religious, philoso*
HINDU CHEMISTRY 23
phical, mathematical were known in India in the
sixth century B. C. The coincidences are so
numerous that their cumulative force becomes con-
siderable. The transmigration theory, the assump-
tion of five elements the Pythagorean theorem
in geometry, the prohibition as to eating
beans, the religio-philosophical character of the
Pythagorean fraternity and the mystical specu-
lations of the Pythagorean school, all have their
close parallels in ancient India. The doctrine of
metempsychosis in the case of Pythagoras appears
without any connection or explanatory background,
and was regarded by the Greeks as of foreign
origin. He could not have derived it from Egypt,
as it was not known to the ancient Egyptians. In
spite, however, of the later tradition, it seems
impossible that Pythagoras should have made
his way to India at so early a date, but he could
quite well have met Indians in Persia."^

himself sums up his views in these words : "I should be disposed
to conclude that the Indians were in this instance teachers * than
learners." " Trans. Roy. As. Soc," Vol. i., p. 579. Prof.' H. H.
Wilson observes : "that the Hindus derived any of their philo-
sophical ideas from the Greek seems very improbable, and if
there is any borrowing in the case, the latter were most probably
indebted to the former." Preface to the Sdwkhya Kdrikd

A Discourse on the Tastes their Relationship

to the five primal elements the
Nature of the Alkali
''Once on a time, the son of Atri, and Bha-
drakapyas âkunt^ya and the full-eyed Maudgalya,
and the golden-eyed Kau^-ika, the sinless Bharadvaja
otherwise called Kumaraîras, the blessed king Vary-
ovida, that foremost of all intelligent men Nimi, the
ruler of the Viflfehas, Va^fiâ of high intelligence,
and Kawkhayana-valhika, that foremost of all
physicians of the Valhika country, these -ff/shis,
all of whom were old in years and learning and
all of whom had subjugated their souls, came
together to the delightful Chaitraratha woods,

and pleasure. As those /?/shis conversant with
every topic were seated there, the following
discourse of grave import took place among them
on the subject of the proper ascertainment of
the (different) tastes and food.
"There is one kind of taste said Bhadrakapya;
which persons skilled in the subject regard as are
of the five subjects of the senses, viz.y that which
relates to the tongue. That, again, is not different
from water.
**The Brahma;ia .âkunt^ya said there are two
tastes, their virtues being that one of them cuts or
removes from the body all bad humours or ingre-
dients, and the other only checks or curbs them.
''There are three tastes, said the full-eyed
Maudgalya. Their virtues are cutting, curbing, and
both.
"There are four tastes, said the golden-eyed
Kauîka. They are agreeable and beneficial, and
agreeable and non-beneficial, disagreeable and
beneficial.
"There are five tastes, said Kumarayira-
Bharadvaja. They appertain to Earth, Water, Fire,
Air and Ether (or Space).
"There are six tastes, said the royal sage
HINDU CHEMISTRY 27
Varyovida. They are heavy, light, cold, hot, oily
and dry.
''There are seven tastes^ said Nimi, the ruler
of the Videhas They are sweet, sour, saltish,
pungent, bitter, astringent and alkaline.
"There are eight tastes, said Varfiâ-Dhamargava.
They are sweet, sour, saltish, pungent, bitter,
astringent, alkaline and that which remains in an
unmanifest form.
''The tastes are infinite in number, said Kam-
khayana, foremost among the physicians of the
Valhika country, in consequence of the infinite
variety of their virtues, operations or effects and
methods of corrections (or mixture for adding to
their virtues, etc.,).
"The illustrious son of Atri, vijs.y Punarvasu,
said that the number of tastes is truly six. They
^re sweet, sour, saltish, pungent, bitter and astrin-
gent. The source from which these six flow, /. e.
their origin, is water. Their operations or effects
are of two kinds, viz., cutting and curbing. In
consequence, again, of mixture or combination, they
become both cutting and curbing at the same
time. Agreeable and disagreeable are their
divisions that depend upon the likes and dislikes
of men. Beneficial and non-beneficial are their
28 HINDU CHEMISTRY
powers. The refuge of the tastes are the modi-
fications of the five primal elements (of Earth,
Water, Fire, Air and Ether or Space). The tastes,
again, depend upon the (original) nature of their
refuge, the modifications of that refuge, combina-
tions of the substances that form their refuge, as
also place, and time. *
"The virtues or properties (attaching to the
tastes) occur in those which constitute the refuge
(of the tastes), called objects. Those virtues are
heavy, light, cold, warm, oily, dry and others.
^^Kshdra (alkali) is so called from its being-
produced hy ksharana (dropping down or straining) .
This is not a taste. It is, on the other haiid, an
object. It is, in fact, produced from many kinds of
taste. Hence, it has many tastes. Among them,
pungent and saline predominate. It is composed
of many objects of the senses. It is manufactured
with the aid of different processes.
(i) The modifications of the five primal elements constitute

the refuge of the tastes. Every substance is. formed by modifi-
cations of those elements. What is said, therefore, is that material
substances are the refuge of the tastes, i^. the tastes inhere
in them.
HINDU CHEMISTRY 29
"At the outset, however, we shall say something
referring to the diversity of objects (which are the
refuse of the tastes). All objects are the results of
the combinations of five primal elements {vtJ3.j
Earth, -Water, Fire, Air and Ether or Space). As
regards Medical Science, object are of two kinds,
vij3.y those endowed with animation and those that
are inanimate. The attributes which inhere in
objects are sound, &c., heaviness &c., ending with
solubility.^'*

Preparation and Use of Alkalies and
Alkaline Caustics.'
"Of all cutting instruments and accessory cutting
instruments, caustics are superior inasmuch as
they perform the work of incisions, punctures
and scarifications, relieve derangements of the
three humours, z//<3r., air, bile and phlegm, and
uniformly affect the diseased part to which they
are applied. Kshdra (caustics) are so called
(i) Chikitsi Ch. I. 5, pp. 497-98.

(3) We have adopted Udoy Chand Dutta's Translation of
Chs. XI and XIV with certain corrections here and there.
HINDU CHEMISTRY 33
because they remove diseased parts and destroy
the skin and flesh. From being composed of
numerous medicines they can affect the three
humours. Caustics being white in colour are cooKng
or of lunar origin.* This origin is not inconsistent
with their burning, escharotic and lacerating pro-
perties. Being composed of numerous heating
medicines, caustics are acrid, hot and pungent.
They promote suppuration, destroy parts, improve
unhealthy sores and promote granulation, dry up
discharge, stop bleeding and abrade the skin.
Their internal use removes worms, acidity, phlegm,
skin diseases, some poisons and corpulence. Their
excessive use causes impotence.
** Alkalies are of two sorts, namely, for external
application and internal administration. They are
used externally in the skin diseases called kusthuj
in keloid, ringworm leucoderma, lepra, fistula-in-
ano, tumours, unhealthy ulcers, sinuses, condyloma,
moles, chloasma, brown spots on the face, warts,
external inflammations, worms, poisons and piles,
and in the seven following diseases of the mouth
(i) The reader will not fail to notice that silver nitrate is, in
the language of Western Alchemy, named lunar caustic,

namely, upajihvd (ranula), adhijihvd (tumour on the

tongue), upakusa (inflammation of the gum),, danta*
vaidarbha (inflammation of the gum from injury),,
and the three sorts of rohini or inflammation of the
throat. In these diseases of the mouth, accessory^
instruments, in the shape of caustics only, should be
used. Alkaline solutions are administered internal-
ly in chronic or slow poisoning, abdominal tumours,,
ascites, loss of appetite, indigestion, disinclination
for food, tympanitis, urinary deposits, calculi, inter-,
nal or deep-seated inflammation, intestinal worms,
poisoning and piles. Alkalies do not agree with
children, old and weak people, and persons havings
a tendency to haemorrhage from internal organs, or
a bilious temperament. They are injurious in fever,
giddiness, intoxication, fainting, amaurosis and such
other diseases.
" Alkalies for escharotic use are prepared like-
other alkalies by straining alkaline solutions as else-
where explained in detail. They are made of three
strengths, namely, weak, moderate and strong. He
who wishes to prepare alkalies should in an auspi-
cious day in autumn, fasting and in pure body, select
a middle-aged, large-sized, uninjured ghantdpdtalt
tree with black flowers {Schrebera swietenioides)
growing on an approved spot on a mountain, and
HINDU CHEMISTRY 35
address it with certain mantras or incantations as a
preliminary ceremony called adhivdsa. Next day
the tree should be cut or killed after reciting the fol-
lowing mantra or prayer : *' Oh you with great
fiery power may not thy strength be lost ! Oh you
auspicious tree, stay here and accomplish my work.
After accomplishing my work you will go to heaven."
Then the ceremony of homa^ or burning the sacri-
ficial fire, should be performed with one hundred red
flowers. The tree should then be cut to pieces and
piled in a place free from wind. Some limestone
should be placed on the pile which should be set on
fire by stalks of Sesamum Indicum. When the fire
is extinguished, the ashes of the ghantdpdtali tree
and the burnt lime should be k^pt separate. In the
same way the following trees may be burnt with their
root, branches, leaves and fruits for the preparation
of alkalies,* namely :
Kutaja Hollarrhena antidysenterica.

LiXIVIATION OF THE ASHES
** Thirty two seers of ashes should be stirred or
mixed with six times their quantity of water or cow's
urine and the mixture strained through clothe This
should be repeated twenty-one times. The strained
fluid should then be boiled slowly in a large pan and
agitated with a ladle. When the fluid becomes clear^
HINDU CHEMISTRY 37
pungent and soapy to the feel, it should be removed
from the fire and strained through cloth. The fil-
trate^ being thrown away, the strained fluid should
be again boiled. From this alkaline solution take
three quarters of a seer.*'
Rendering the Alkali Caustic
"Then take eight palas each of Banduc nut,
burnt limestone, conch shells, and bivalve shells
and heat them in an iron pan till they are of
the colour of fire. Then moisten them in the
same vessel with the above-mentioned three-
quarters of a seer of alkaline water and reduce
them to powder. This powder should be thrown
on sixty-four seers of the alkaline water and
boi ed with constant and careful agitation by
the ladle. Care should be taken that the solution
is neither too thick nor thin.*'
How TO Store up the Alkali
"When reduced to proper consistence, the
solution should be removed, from the fire and
poured into an iron jar. The opening or mouth of
(i) This is evidently a mistake. According to the original

text, it should be "the dregs" u e, the precipitate.
38 HINDU CHEMISTRY
, the jar should b^ covered, and should be kept in a
secluded . place. This preparation is called
madhyama kshara or alkaline caustic of middling
strength. When the alkaline water is simply
boiled to the proper consistence without the addi-
tion of burnt shells, &c., the preparation is called
mridu^ kshara or weak alkaline solution. The
strong alkaline caustic is prepared by boiling the
weak solution with two tolahs each in fine powder
of such of the under-mentioned ingredients as are
available, namely: -
Dantr, Baliospermun mon anum.
Dravanti Salvinia cucullata.

(i) "Mridu" may be rendered more accurately as *' mild."
HINDU CHEMISTRY 39
* ^^^vyN^ \^ \
lies should be used according to the state of the

disease. In weak persons, the alkaline water with-
out the addition of other caustic ingredients, should
be applied to strengthen the parts."
Characteristics of the Good and the
Bad Alkali
On this subject there are the following verses :
" Good alkaline caustics should be neither too
strong nor too weak. They should be white in
colour, smooth and soapy to the touch, should not
spread beyond where they are applied, and act
rapidly and successfully. These are the eight good
properties of caustics. Their bad qualities consist
in their being too weak or cool, too strong or hot
too slippery and spreading, too thick or too under-
boiled, or they may be deficient in ingredients.
** In applying caustic to a patient suffering from
a disease curable by this remedy, he should be made
to sit in a spacious place, protected from wind and
sun. The physician should then procure the ins-
truments or necessary articles'accordingto the rules
laid down in the fifth chapter. He should theil exa-
mine the diseased part, rub, scarify or scratch it,
and then apply the caustic by means of a probe, and
40 HINDU CHEMISTRY
t^^^^^r-^^*.*^
wait for the space of time required to utter one

hundred words. The diseased part turns black on
the application of the caustic which is a sign of its
having been burnt. The application of some acid'
mixed with clarified butter or honey relieves the
pain. If from the thickness of the burnt part, it
does not fall oflf, the following application should be
thoroughly applied to it, namely, equal parts of
tamarind pulp, of the refuse of kdnjika (fermented
rice water i.e. crude vinegar), sesamum seeds and
liquorice root rubbed together into a paste. Sesamum
seeds and liquorice root rubbed together with
clarified butter promotes granulation in ulcers."
Why the Acid Neutralises the Alkali
" If you question, my son ! how is it that the
application of the pungent acid of kdnjika relieves
the burning of the fire-like hot alkaline caustic, then
hear the following explanation from me. Alkalies
possess all the tastes except that of the acid. The
acrid taste prevails in it and the saline one to a less
degree (cf. ante p. 28). The sharp saline taste
when mixed with acid becomes very mild, and gives
up its sharp quality. From this modification of the
saline taste, the pain of caustics is relieved just as
fire is extinguished by water.'*
HINDU CHEMISTRY 41
Mild and Caustic Alkalies
It will be noticed that there is a distinct mention
of " mild " and *' caustic " alkalies in the body of the
text. The process of lixiviating the ashes and ren-
dering the lye caustic by the addition of lime leaves
very little to improve upon, and appears almost
scientific compared to the crude method to which.
M. Berthelot pays a high tribute :
" Fabrication de la Lessive : Quatre muids de
cendres sont repartis entre deux cuviers, perces de
trous au fond. Autour du trou le plus petit, du cote

Description of Blood
(Chapter XIV of Siitrasthanam)
"The four varieties of food derived from the five
elements and having the six tastes, the two pro-
perties of heat and cold or according to some, eight
properties and many qualtities when taken in moder-
ation and thoroughly digested, produces a fine
substance imbued with energy and fire. This is
called rasa (chyle). The heart is the seat of the
rasa or chyle. From the heart it proceeds through
34 arteries, namely, ten ascending, ten descending,
and four transverse to all parts of the body. By
some unseen cause or destiny, this chyle continually
satiates, increases, nourishes and supports the
body and keeps it alive. The motion of this chyle
txA the body is inferred form the processes
le, increase, and diseased condition of the
: portions of the body. It may be asked
this chyle which pervades all the external
the body, the three humours, the tissues,
HINDU CHEMISTRY 43
including the blood and the receptacles of the
secretions, is endowed with the property of heat or
cold. As this chyle is a circulating fluid, and as it
softens, vitalises, supports and nourishes the body,
it should be known to possess the cooling property.
This watery fluid no doubt assumes a red colour in
the liver and spleen, that is, it is converted
into blood in these organs. On this subject
there is the following verse :
** The rasa (chyle) of living beings is coloured
red by healthy bile. This coloured fluid is called
blood. The blood excreted by women and called
the menstrual fluid is derived also from this rasa.
This menstruation, coming at the age of twelve,
ceases at the age of fifty.
" The menstrual fluid is endowed with the pro-
perty of .heat, owing to the womb being possessed
of both the properties of heat and cold. Other
writers say that the blood of living beings is
composed of the five elements. The five qualities
of the five elements as seen in blood are as .follows,
namely, fleshy smell, liquidity, red colour, tendency
to trickle or ooze, and lightness.* Blood is produced
(i) Cf. ante pp. 6-7- under Vaweshika Philosopy.
44 HINDU CHEMISTRY
^ 0^,^'^^\^
from chyle, flesh from blood, fat from flesh, bones from
fat, marrow from bones, and lastly the semen is
produced from marrow. The chyle produced from
food and drink nourishes these constituent parts
of the body. Living beings are produced from
the rasa ; hence sensible people should carefully
preserve this rasa by conforming to the proper
rules of diet and regimen.'

Internal use of Lead and Tin
Lead and tin are described as vermifuge a
property also accepted by the later latro-chemists.
Powdered tin rubbed for seven days together
with the creamy portion of curd is recommended
for internal administration.
Minerals for External Application
For the treatment of ulcer an external applica-
tion of sulphate of copper, sulphate of iron,
orpiment and realgar, &c., is prescribed.

Roasting of Iron and other Metals, so as
TO Render them Fit for Internal
Administration.
Thin leaves of cast iron are to be smeared with
the levigated powder of " the salt " and heated in
the fire of the cow-dung cakes and then plunged
into a decoction of the myrobalans and asafcetida.
This process is to be repeated 1 6 times. The leaves
are then to be ignited in the fire of the wood of
mimosa catechu and afterwards finely powdered
and passed through linen of fine texture.
The above process is equally applicable to the
roasting of the other metals. *
The Origin of Bitumen
The origin of bitumen is much the same as in
the Charaka and the Bower Ms. ; the only difference
(i) Chikitsitasthdnam Ch. XIX, 37, ed. J. Vidy^lsdgara.

HINDU CHEMISTRY 47
being that, according to Sujruta, bitumen is related
to six instead of four metals (see below p. 53).
Iron Pyrites
Iron Pyrites are collected on the bank of the
river Tapi, of the lustre of gold and silver respec-
tively (see below under ** Rasaratnasamuchchaya ^',
Bk. II, 77-81 and prescribed in the treatments of
diabetes, leprosy, &c.
Gold Dust
Gold dust, mixed with lotus seed, honey, &c. is
used as a tonic.

The Poisons are classified as animal, vegetable
and mineral respectively. Under the last we have
Phenasma bhasma^ and orpiment.

the metallic salts. The much reputed "potable
gold" in the shape of the chloride of the metal
was probably in this way obtained. It will be
interesting to note the successive stages in the
-evolution of the cherriical processes as we proceed.
(See below especially under " Chemistry in Rasar-

named "viâ" and consists of green vitriol, alum,
common salt, salt-petre, &c.).
The reader will find an analogy in the ancient
Egyptian and Greek methods as preserved in the
Leyden Parchment, one or two extracts from which
cannot fail to be of interest. It may be added by
way of explanation that mineral acids being un-
known to the ancients they had often to take
recourse to the roundabout way of heating metals
in combination with a mixture of blue vitriol, cop-
peras, common salt and so on (see under " Mineral
Acids") inorder to get their salts.

(i) Dardistan,the mountainous region about Kd^mir, is famous

for the ores of cinnabar from which mercury is extracted. Darada is
in fact a name of cinnabar. The auriferous region of the Daradas
is mentioned by Humboldt (Kosmos 11. p. 513 E. C. Otte) who
places it either in the Thibetan highlands east of the Bolor chain^
west of Iskardo, or towards the desert of Gobi described also as
auriferous by. Hiouen Thsang. Regarding Pclrada and Darada
see also Lassen's Alterthumskunde, i. pp. 848-49. It seems pro-
bable that "parada" (quicksilver) and "darada" (cinnabar) owe
their names to the countries from which their supply was obtained.

The Rasas.
[In the Hindu Materia Medica the mineral
kingdom is broadly divided into the Rasas and
the Uparasas, the Ratnas (gems) and the Lohas
(metals). The term Rasa is in general reserved
for mercury^ though it is equally applicable to a
mineral or a metallic salt. In the oldest medical
works, e. g. the Charaka and the Su^ruta, Rasa
has the literal meaning of juice 01: fluid of the
body, which according to the notions of humoral
pathology engenders blood, serum, sweat, &c.,
(see p. 42). Rasakriya^ in the Sujruta means
fluid extract or concentrated decoction. As mer-
curial and metallic preparations gradually came
into vogue and even began to supplant the vege-
table drugs, the term rasa began to be substituted
for quicksilver on account of its semi-fluid character
and its supposed miraculous therapeutical action
on the juices or humours of the body (Cf. -??/g-Veda,
"Somarasa'' : Vide Intro.) In the Bavapraka^-a we

find rasa used in a two-fold sense, ancient and

comparatively modern.^
In the older works Rasayana (derived from
rasuy juice, and ayana^ way) means a medicine
preventing old age and prolonging life the Elixir
vit(B'} Later on Rasayana was almost exclusively
applied to the employment of mercury and other
metals in medicine and at present it means also
alchemy (chemistry). Our author uses the term

Mica, the layers of which can be easily detach-

moon and which has the lustre of the rust of iron,,
does not take up or combine with (lit. swallow)
mercury. That which has taken up mercury can
alone be used with the metals and administered in
medicine. Mica, which has been killed^ is pres-^
cribed in the treatment of various diseases. The"
variety which has the lustre of the moon, if taken
internally, brings on dyspepsia and urinary dis
orders. 12-14
Mica, heated seven times and plunged into sour
gruel or cow's urine or decoction of the chebulic
myrobalans or cow's milk, is freed from all impuri-

Mica, mixed with paddy grains and reduced to-

Vaikranta has eight faces and six angles, is
slippery and heavy and of uniform or mixed tint.
It has 8 different colours, viz.^ white, red, yellow
blue, with the shades met with in the down of the
pigeon, grass-green, black and variegated 55-56
Vaikranta is a powerful tonic and reckoned
among the sovereign medicines. It is a destroyer
of all (bodily) disorders and is employed in the
place of diamond. 57-58
Vaikranta is purified by being heated three
days with the salts and the alkalies or by digestion
with the acids, urines or a decoction of dolichos
uniflorus and the plantain or of paspalum scrobi-
culatum. It is killed by being roasted in a cover-

Chinese and the Yavanas. 77
Pyrites is of two kinds golden and silvery : the
former is a native of Kanouj and is of golden
yellow colour. The silvery pyrites is associated
with stones and is of inferior quality. 81
Rubbed with the juice of lemons and sulphur

Sulphur
Sulphur is of three kinds : that of the first
quality resembles the beak of a parrot ; that of the
second quality is yellow ; whereas the white variety
is the worst. Another authority says : there are four
kinds of sulphur according as it is of white, yellow,
red and black colour respectively the black
variety is rare.* 12-15
Melted sulphur is poured into the juice of ver-
iesina calendulacea and thus purified.
A vessel which contains milk has its mouth tied
down with a piece of cloth, over which is deposited
finely powdered sulphur; the latter again covered
with an earthen bowl. Heat is applied from above
by burning cow-dung cakes. The melted sulphur
drops into the milk and is thus purified. 24-25
Gairika
Gairika (red ochre) is of two kinds : the one,
pashaâ gairika, is hard and copper-coloured ; the
other is svara gairika /. e. of the colour of gold
(yellow). 46

variety and the latter, the basic or yellowish
variety.] 51
Its essence is to be extracted like that of alum.

TUVARI
TuvarT (alum) : the fragrant earth produced in
the mountains of Surat is known as tuvari, which
dyes cloth and fixes the colour of madder. ^ 59
A second variety of it called phataki or
phullika is slightly yellow . . . Another variety
known as phulla tuvari is white and acid in taste ;
iron changes to copper by the process of lepa [cf.
Bk. VIII, 80, where the term "^^" is used in the
sense of transmutation of the baser metals. The
author seems to convey the idea that alum plays
an important part in this process.] 60-62

Talaka
Talaka (orpiment) is of two kinds : the one is of
a leafy structure, the other is found in balls or cakes
and is of golden colour . . , . and bright. 66
It is purified by being digested in the juice of
cucumber and the alkaline water of the ashes of
sesamum or in lime water. 69
Talaka is to be rubbed with buffalo's urine and
thrice macerated in the decoction of buteafrondosa
of the consistency of honey, and then to be roasted
in a covered crucible and powdered. This opera-

The Anjanas
The Anjanas (collyriums) : of these there are
Sauviranjana, Rasanjana, Srotonjana, Pushpanjana,
and Nilanjana ; their properties are described below.

Nilanjana is a killer of gold [cf. the killing of
gold, silver, iron and copper in Vagbha/a, p. 55]
and induces softness in iron, i.e. readers it easily
pulverizable [as the iron becomes impregnated
with the brittle sulphide of iron ; cf also Bk. viii, 38.]

The essence of the anjanas is to be extracted
like that of realgar.

[We quote below the account given in Dutt's

^'Materia Medicaofthe Hindus" as our author gives
rather scanty information on this point :
** Galena or sulphide of lead is called anjana
or sauviranjana in Sanskrit, and krishna surma in
vernacular. It is called anjana which literally
means collyrium or medicine for the eyes, from the
circumstance of its being considered the best appli-
cation or cosmetic for them. The other varieties
of anjana mentioned are Srotonjana, Pushpanjana
and Rasanjana.
*' Sauviranjana ( ^^^ti^t > is said to be obtained
from the mountains of Sauvira, a country along the
Indus, whence it derives its name. The article
supplied under its vernacular name surma is the
sulphide of lead ore. Sauvira is usually translated
as sulphide of antimony, but I have not been able
to obtain a single specimen of the antimonial ore
from the shops of Calcutta and of some other
towns. The sulphide of antimony occurs in fine,
streaky, fibrous, crystalline, masses of a radiated
texture: The lead ore on the contrary occurs in
cubic masses destitute of rays and is tabular in its
crystalline arrangement.

Surma in the vernacular, and the article supplied
under this name by Hindustani medicine-vendors is
calcareous Iceland spar. ^ It is used as a collyrium
for the eyes, but is considered inferier to the black
surma or galena.
"Pushpanjana (tj^^Ti^sT is described as an alka-
line substance. I have not met with any vernacu-
lar translation of this word nor with any person
who could identify or supply the drug. Wilson, in
his Sanskrit-English Dictionary, translates the term

which help the fixation or coagulation of mercury.
These are the gems : Vaikranta, Suryakanta (sun-

Chandrakanta (moon-stone), Rajavarta (lapis lazuli)
and Garuôdgara, the emerald (lit. derived from the

coral, the cat's eye are also reckoned among the
gems. Thesie are to be carefully collected for the
fixation of mercury.*
(l) The ruby and the zircon are also mentioned. The
Vaikranta "is a kind of gem said to resemble a diamond, and to be
of similar properties." Wilson. Suryakanta and Chandrakd<nta
are gems of fabulous existence, supposed to be formed by the
congelation of the rays of the sun and moon respectively. They
may also refer to some sort of crystals. The description of the
gems, other than diamond, is meagre and vague. The following
extracts from Manimala or "A Treatise on Gems" by Sir Raja
Saurindra Mohan Tagore, Mus. Doc, will, to a certain extent,
make up for the deficiencies.
"Mention is made of gems and jewels in the earliest writings of

Diamond is a bestower of long life, a tonic, an
allayer of the three derangements [namely, of air.
phlegn and bile], a killer of all the ailments, a fixer
of mercury, a subduer of death in short it is like
nectar.
Diamond is digested in the decoction of kulattha
{dolichos uniflorus) or of kodrava [paspulum
scrobiculatum) for three hours and thus purified.
Diamond is to be macerated four times in the blood
of the bug and enclosed in a ball made of the
flesh of the musk-rat and then to be roasted in a
covered crucible 30 times or to be heated 100 times
and plunged in the decoction of kulattha. 34-37
Diamond is to be placed in a covered crucible,
the inside of which has been coatied with realgar,
rubbed with the decoction of kulattha and the
juice of artocarpus lakoocha and roasted 8 times in
succession in the fire of dry cow-dung cakes. It is
then heated 100 times and thrown into pure mer-

Gold
Gold is known to be of five kinds : of which
3 are attributed to mythical and celestial origin ;
the fourth is called kshawija (lit. begot of mines) :
the 5th is obtained by the transmutation of the
baser metals. (See Bk. VIII, 80-83.) 2
Gold is to be purified and killed, as otherwise
[if taken internally] it robs one of strength, virility
and happiness and brings a series of maladies. 1 1
Gold-leaf of the weight of one karsha is to be
smeared with salt and placed between two earthen
saucers and heated on a charcoal fire for an hour
and a half when its true colours will come out. 12
The best method of killing all the metals is
with* the aid of the ashes of mercury.* The next
best is through the agency of the roots, whereas
killing with sulphur is least to be recommended. 13
When a metal is killed with ariloha (meaning :
not clear), it is injurious. Gold-leaves, pierced
with holes and coated with a paste of lemon juice
and the ashes of mercury and roasted ten times
are thereby killed, 14

Gold-leaf is killed by being rubbed with one-
fourth of its own weight of killed mercury and
acid of any kind and roasted eight times.* 17
Silver
Silver is of 3 kinds : namely sahajaw (of mythical
origin), begotten of mines and artificial. 22
Silver melted with lead and borax undergoes
purification Arrange on an earthen dish a
mixture of lime and ashes in a circular row and
place in it silver with its equal weight of lead.
Now roast it over fire until the lead is consumed.
Silver thus purified is to be used for medicinal
purposes.) * (Cf. p. 68) 32-34
(i) This refers to the mistaken notion that the sublimate of
factitious cinnabar (vermilion) contains gold.
(2) It will be seen that although killing with sulphur direct is
not recommended, the gold is in reality converted into the sulphide
and afterwards into metallic gold in a fine state of powder. See
under "Killing of Metals." .

is purified by being melted with lead and the ashes." The process
is practically that of cupellation.
HINDU CHEMISTRY 107

Silver-leaf is to be rubbed with mercury and
the juice of artocapus lakoocha and is to be em-
bedded in sulphur and heated in a covered crucible
over a sand-bath ; when cold, the mass is once
more rubbed with orpiment and acids and roasted
12 times. By this process, the silver is reduced to
ashes 35-37
Silver is reduced to ashes by being 3 times
rubbed with powdered iron pyrites and lemon juice
and roasted in a covered crucible. 38
Take 4 parts of silver-leaf and one of orpiment
and rub them with the juice of lemon and roast the
mixture and repeat the operation 14 times and thus
silver is completely incinerated.* 40-41
Copper
There are two varieties of copper: the one
brought from Nepal is of superior quality ; that
dug out of the mines of other countries is desig-
nated Mlechchha. ^ 44
(i) We shall complete the account with an extract from Ra-
sendrasarasamgraha : "Siver-feaf is pierced with holes and smeared
with twice its weight of cinnabar and subjected to distillation in
the Patana Yantra (see Bk. ix on apparatus). The mercury comes
off and killed silver remains behind."

Copper-leaf is killed by being rubbed with
lemon-juice, sulphur and mercury and roasted thrice

Iron
There are three kinds of iron : namely, mundaw?
(wrought iron), tiksh/â;^ and kantam ; mundaw^
again is of 3 varieties ; viz., mr/du, ku^Mam and
\i2idhrdim.
That which easily melts, does not break and is
glossy is mr/du ; that which expands with difficulty
when struck with a hammer is known as kuwMaw ;
that which breaks when struck with a hammer and
has a black fracture is kaâra;^. 1^'T^
Tikshwaw (properly cast-iron, steel) : there are
6 varieties of it. One variety is rough and free
from hair-like lines and has a quicksilver-like
fracture and breaks when bent. Another variety
breaks with difficulty and presents a sharp edge.
75-7
Kantaw : there are 5 kinds of it, namely,
bhramaka, chumbaka, karshaka, dravaka and roma-
kanta. It possesses one, two, three, four and five
faces and often many faces [with which to attract
iron] and is of yellow, black and red colour respec-
tively. The variety which makes all kinds of iron
move about is called bhramaka, that which kisses
HINDU CHEMISTRY 109

iron is called chumbaka, that which attracts iron is
called karshaka, that which at once melts the iron
is called dravaka (lit. a solvent) and the fifth kind
is that which, when broken, shoots forth hair-like
filaments' 84-89
Mercury is like an intoxicated elephant and
kanta/w is like the bent hook wherewith to restrain
it. The wise man digs it out of the mines. That
which has remained exposed to the sun and the
atmosphere is to be avoided.* 92-93
If water is kept in a vessel and oil poured over
it and the oil does not spread about ; if asafcetida
gives up its odour and decoction of neem (Melia
azadirachta) its bitterness and milk, being boiled
in it, does not overflow but rises high like a peak
if such be the characteristics of the vessel, know
that it is made of kanta iron. 94
Powdered iron is to be macerated awhile in the
decoction of the three myrobalans, in cow's urine
and then to be mixed up with clarified butter and
fried in an earthen vessel and stirred with an iron
rod until a blade of straw thrown over it catches
fire. The iron powder is to be pounded and the
above process repeated five times.

powdered in a stone mortar with an iron pestle
* * * The powder of iron thus obtained is to
be roasted twenty times in a covered crucible in
combination with mercury and sulphur, and after
each roasting the powder of iron is to be pounded
as directed above iron thus reduced to ashes is to
be used in medicine. 107-110
Take one part of iron and twentieth part of its
weight of cinnabar and rub them with lemon juice
and sour gruel and roast the mixture in a covered
crucible. The operation being repeated 40 times,
kantaw, tikshaw and .munda are killed of this
there is no doubt. 113-114
Take of mercury one part, sulphur two parts
and iron powder three parts and rub them with the

Gold and other metals can be killed by this process,
after being reduced to fine powder like iron.

Rust of iron is to be heated and powdered till
it is reduced to fine powder this is called
mawdiira.* 147
The qualities which reside in killed iron are
also to be found in the rust of iron, hence the latter
may be substituted for the treatment of diseases. '

Tin
Vanga/ (tin) is of two kinds kshuraka/w and
mlyrakawz ; the former is endowed with superior
qualities ; the latter cannot be recommended for
medicinal uses. 153

variations. According to it the powder is so fine that it "floats or?

odour. In connection with this it is interesting to read Professor
W. E. Ayrton's address " On the Smell of Metals "Brit. Assoc.
Rep. 1898, p. 772. Cf. also "Alch. Syr." Trad., 121, as well as the
opening lines of the present Book describing tin and lead " as
metals of foetid odour." In the Syrian Alchemy " Silver is dis-
tinguished from tin by its absence of foetid odour " ; regarding this
M, Berthelot very pointedly remarks : " on voit que I'odeur propre

Brass, Bell-Metal, &c,
Pittala (brass) is of 2 kinds ritika and kaka-

into sour gruel turns copper-coloured. 192-193
Brass, which is heavy, soft, of yellow colour,
capable of resisting strokes, is to be recommended.

Brass, which is light and of eflfensive odour, is
not good for medicinal purposes, 196
Brass, smeared with a paste of lemon juice,
orpiment and sulphur and roasted 8 times, is re-
duced to ashes. The process of killing brass is the
same as that of copper. 201-202
Kawsya (bell-metal) is made by melting together
8 parts of copper and 2 parts of tin. 205
It is completely killed by being roastad 5 times
with sulphur and orpiment. 210
Vartalohaw is produced from Kiiwsya, copper,,
pittala, iron and lead ; hence it is regarded by
metallurgists as an alloy of 5 metals
It is killed with the aid of sulphur and orpiment.

Initiation into Discipleship

[This chapter is full of directions for the mystic
Tantric rites after the performance of which the
pupil is to be initiated into the secrets of mercurial
lore.]
The instructor must be wise, experienced, well-
versed in chemical processes, -devoted to .îva and
liis consort Parvati sober and patient. The pupil
should be full of reverence for his teacher, well-
behaved, truthful, hard-working, obedient, free from
pride and conceit and strong in faith. 3-7
Chemical operations are to be performed under
the auspices of a ruler, who is God-fearing, who
worships .Sîva and Parvati and whose territory is
free from anarchy ; and the Laboratory, to be
-erected in the depth of a forest, should be spacious,
furnished with 4 doors and adorned with the
portraits of the Gods. 13-15
Take of gold-leaf 3 niskas in weight and quick-
silver 9 niskas and rub them with acids for 3 hours.

The capacity of mercury to swallow food [i. e.
to combine with certain substances or to take up
the qualities inherent in them] is known as grasa-

Mercury, alloyed with one-sixty-fourth part of
its weight of gold or silver acquires a mouth where-

Lepa, kshepa and kunta signify dhiima i. e.
smoke. By the process of lepa is meant the
conversion of iron into gold or silver. 80
The conversion of iron into gold or silver with
the aid of mercury thrown into a smoky flame,
emitting vapour, is known as dhumavedha (lit.
pierced by smoke). 83
The conversion of a small quantity of a metal
into gold through the agency of mercury. . . .
. . .which has acquired a mouth (see ^loka 68),
is called âbdavedha.* 84

Earth which is heavy and of a pale colour,
sugar or earth from an ant-hill or earth which has
126 HINDU CHEMISTRY

been mixed with the burnt husks of paddy, fibres of
the hemp plant, charcoal and horse-dung pounded
in an iron mortar and also rust of iron are to be
recommended for crucible-making. 5-6
V^/NTAKA Crucible
A crucible of the shape of the fruit of br/njal
(Solanntn melong) to which is attached a tubulure,
which is expanded towards its mouth like the
flower of Datura s., , . , and which is either J2 or
8 digits in length, is suitable for the extraction of
Ihe essence of calamine and other readily fusible
minerals. 23-24
[The particular kind of crucible described here
is the same as referred to in the extraction of zinc
from calamine in the couplets 157-161, Bk. II.]

kinds of crucibles to be used for different chemical
operations.]
Calcination, Roasting, &c.
When metals have undergone roasting they
<:annot be roasted to their former condition {i.e.
they lose their own properties) and they acquire

superior qualities, fill up the lines in the fingers
and do not sink in water.* 51
A quadrangular pit 2 cubits in length, breadth
and depth respectively is filled with 1,000 cow-dung
cakes. The drugs to be roasted are placed in one
crucible ; this is covered with a second, the rims
being luted with clay. The crucibles are deposited
over the cow-dung cakes and 500 more thrown over
them : fire is now applied. 54-55

On the Purification of Mercury
I am now going to describe briefly the various
processes for the purification of mercury after
having consulted Rasarâva and other works. lo
There are 3 natural impurities in quciksilver,
visha (poison), vawhi (fire) and mala (dirt, dregs)
and two artificial, due to its being alloyed with lead
and tin.' 14-15
(i) Cf. Rasendrachintamawi :

" Trades-people fraudulently adulterate quicksilver with lead
and tin, htence it is to be freed from these artificial defects [impu-
rities] by means of three distillations " as given above under
Tiryakpatand (p. 124).
HINDU CHEMISTRY 131

Hence for the purification of mercury, the oper-
ations (named below) are to be undertaken with the
aid of appliances and skilled assistants. 20
In an auspicious day and under the influence of
a benign star, a quantity of mercury weighing 2,000

gold of course is left behind. The general belief is that by associa-

work, Rasapradipa, is sceptical about the part which gold plays
and recommends its being left out.

the Hindu latro-Chemists. The reader will find

much useful information in the followng extract.
'This combustibility of the diamond appears to
have been observed at an early period, although
the fact does not seem to have attracted the general
attention of the older chemists, as statements of a
contrary character are recorded by them. Thus,
for instance, Kunkel states that his father, at the
command of Duke Frederick of Holstein, heated
diamonds in his gold-melting furnace, for nearly
thirty weeks, without their undergoing any change.
It is to Newton, however, that we owe the first
argument which went to prove that the diamond
was capable of undergoing combustion on account
of its high refractive power, a property characteris-
tic of the class of oily bodies. In the second book
of his Opticks, Newton says upon the subject,
*^ Again the refraction of camphire, oyl-olive, lint-
seed oyl, spirit of turpentine and amber, which
are fat sulphureous unctuous bodies, and a diamond,
which probably is an unctuous substance coagulated,
have their refractive powers in proportion to one
another as their densities without any considerable
variation." The conclusion to which Newton was
led by theoretical considerations was experimentally
proved to be correct in the year 1694-5 by Averami

and Targioni, members of the Academia del Cimento,

who, at the request of the Grand Duke Cosmo III., of
Tuscany, placed a diamond in the focus of a large
burning-glass and observed that it entirely disap-
peared. Francis I., who is said to have received
from an alchemist an anonymous receipt for melting
diamonds, exposed, in the year 1751, diamonds
and rubies of the value of 6,000 gulden for twenty-
four hours to the action of a powerful fire ; the
rubies were found unaltered, but the diamonds had
altogether disappeared. The volatilization of the
diamond by means of heat was from this time
forwad made the subject of numerous experiments.
Thus, Darcet observed in 1766 that diamonds dis-
appear when they are heated in a cupel-furnace,
even in closed crucibles, but, continuing his experi-
ments at the request of the Paris Academy, he,
together with Rouelle, found that when heated
in perfectly hermetically-sealed vessels, the diamond
did not disappear. Macquer, in the year 1771,
was the first to observe that when the diamond
undergoes volatilization it appears to be surround-
ed by a flame. In conjunction with Cadet and
Lavoisier, he afterwards found that a true com-
bustion takes place. In continuation of these ex-
periments Lavoisier, together with Macquer, Cadets

8 Faces and 6 angels " might possibly also refer
to the hexagonal prism with basal planes, a com-
mon form of corundum, which gives the variety of
colours referred to even more perfectly than the
spinels.
But the remarks on p. 104 as to the "lique-
faction " of this mineral, cannot apply to either
spinel or corundum. Unless there is some failure
to appreciate the original meaning the statements
are nonsensical.

Iron pyrites [Fe S^] is brass-yellow in colour,

yellow; but there are other pyrite-like minerals
which are silvery white ; for instance, cobaltite
(Co Sg. Co. Asjj), smaltite (Co As^), lollingite (Fe As^

roasted in air would give a red residue of Fe^ O5.

colour and besides which iron-pyrite when freshly
fractured would appear almost silvery in colour.

ferruginous dirt due to oxidation of the ferrous
sulphate produced by similar causes with the other
sulphates.
Vajra/ : the remarks " 8 faces and 6 corners ''
would be correct for an octahedral crystal of
diamond ; but I know of no crystal form which has
at the same time " 8 angles." The faces of the
diamond are frequently rounded, which may account
for the statements about the " female" and " neuter"
-diamonds. Many transparent minerals give a
play of colours through either schillerization or
refraction ; but the diam6nd is of course particularly
noticeable on account of its high dispersive power."

*' Rajputana Copper ores are found in several
of the independent States of Rajputana, and also
in the British district of Ajmir. Mining has been
practised on a large scale, but at present the trade
of miner is becoming extinct and the operations,,
which are only carried on in a few of the localities,
are of a very petty nature.
** The names of the States in which there are
mines are as follows : Alwar, Bhartpur, Jaipur,.
Udepur, Bundi and Bikanir.
** Alwar State. According to Mr. Backet there
are ancient copper mines at the following localities
in this state ; Daribo, Indawas, Bhangarh, Kusal-
garh, Beghani, Pratabgarh, Tassing, and Jasing-
pura. The most important of this is the first.
** Deribo. The mine is situated on a sharp
anticlinal bend in a thin band of black slates inter-
calated in the Alwar quartzites. There appears to-
be no true lode ; the one, which is pyrites mixed
with arsenical iron, occurs irregularly disseminated
through the black slates, a few specks and stains
only being seen in the quartzites ; occasionally rich

nests of ore were met with From an
interesting account by Major Cadell, the following
facts regarding the manufacture have been ex-
tracted. The ore, as usual in the native process,
is pounded, made up into balls with cow-dung,
roasted, and then smelted in a closed furnace and
refined in an open charcoal fire. Thirty pounds
of ore require four times that quantity of charcoal
and yield 5^ pounds of metal, or 16.6 per cent.
During the last 12 years the average annual out-
turn has been only 3 tons 8 cwts., and it is dimin-
ishing owing to the influx of European copper.
** Singhana (Jaipore State). ^l^he copper mines
at Singhana are situated in rocks belonging to the
Arvali series. The earliest account of these mines,
which is believed to have been by Captain Boilcan,
was published in the year 1831. The principal
productions were copper, blue vitriol or copper
. sulphate, alum, and an ore of cobalt called sehta
or salt a,
"The mines are described as being tortuous
and of great extent ; at the working faces it was
the custom to light fires which caused the rock to-
split up. Lamps were used which the miners
carried on their heads and with a gad and hammer
. -extracted the ore. The principal ore found appears
142 HINDU CHEMISTRY
to have been pyrites. It was sold retail by auction

to the' proprietors of different furnaces.
" The pounding or crushing was effected on a
stone anvil with a hammer weighing eight or ten
seers ; when completely reduced to powder the
ore was made up into balls with cow-dung and
roasted. The blast furnaces {vide illustrations)
were prepared in the following manner. A quantity
of common sand was spread on the door of a
circular hut, in the centre of which a depression,
12 to 15 inches in diameter and 2 or 3 inches deep,
was made ; in this a layer of fine sand and another
of ashes were laid to prevent the metal from
adhering to the bottom of the receiver ; two clay
nozzles or tuy^rs were then placed on opposite
sides of this hollow and a third between them,,
leaving the fourth side vacant for the slag to escape-
The nozzles were then connected by moist clay
and a circular rim of mud, a few inches in height^
was raised, on which three annular vessels of fire-
clay were placed to form the body of the furnace,
.each of these was 15 inches in external diameter,,
10 inches high, and 3 inches thick. They were used
repeatedly, but the lower part of the furnace had
to be reconstructed for every charge. The bellows
were simply goat-skins connected with the nozzles,

and were worked by the families of the smelters.
After a preliminary firing, to dry the mud, the
furnace was charged with charcoal, roasted ore
and iron slag, the latter being employed as a flux.
*' In a day of nine or ten hours* duration, 3
maunds of charcoal, 2^ of the roasted ore, and 2 of
the iron slag were consumed. The slag was drawn
off and the smelted copper which had accumulated
at the bottom of the furnace was removed on the
following day. It was then re-melted and refined
in an open furnace under a strong blast from bel-
lows, and cast into small bars or ingots, which
were subsequently removed to the Mint and cut
up and fashioned into coins.
"The ore was said to yield only from to 2^ to
7i per cent, of metal, but the profits must have
been not inconsiderable as the Khetri Raja is said
. to have claimed one-sixth of the value of the copper
in addition to Rs.. 14,000 received for the lease.
The quality of the metal is said to have been
inferior to that of Basawar, this being attributed to
the use of the iron slag as a flux
;. .. . Considerable quantities ^ of blue vitriol
(copper sulphate), alum, and copperas (iron sul-
phate) are manufactured from the descomposed
slate and refuse of the. mines^ The slates are

steeped in water, which is afterwards evaporated

in large iron vessels, when the blue vitriol, is
crystallized out, afterwards the alum, and lastly the
copperas. Mr. Mallet found traces of nickel and
-cobalt in all three of these substances.
" Copper smelting in the Singhbhum District
(Bengal). Indications exist of mining and smel-
ting having been carried on in this region from a very
early period, and the evidence available, points to
the Seraks or lay Jains as being- the persons who,
perhaps 2,000 years ago, initiated the mining.*
The number and extent of the ancient workings
testify to the assiduity with which every sign of the
presence of ore was exploited by these early
pioneers and those who follow them up to recent
times."
The Treatise on Alchemy attributed to Bubacar
(loth to nth century A. D.) also contains many
similar descriptions of the gems and minerals ;
spiecially noticeable is the classification according
to sex male smA female (cf. Bk. IV, 27-28, p. 100).

Alum and Green Vitriol
Dutt speaking of alum states : *^ it is not men-
tioned by Su^ruta, in his list of metallics, but later
writers give its synonyms and uses." This is
evidently incorrect. Alum," with green vitriol, is
distinctly referred to in the Su^-ruta, e. g\'
Sutra, xxxvi, 12.
In the above jloka surdshtrajd, lit., begot of
Surashtra (modern Surat), is. used in the sense of
alum. From the ancient tiines the ** earth of
Surat " has been known to yield this mineral.
Amara Si/ha in his Lexicon, written sometime
r
between 400-600 A. D.,* gives among others the
following synonyms of alum : kawkshi, tuvari and
surashtraja. " Rasaratnasamuchchya " also gives, the
same ' synonyms. (Bk. ill., 59-62). The manu-
facture of alum survives to our own days, as the
following description will show :
" Alum shales, so called, are of rare occurrence
in peninsular India, and, so far as it known, ' the

only considerable native manufacture is situated
in Rajputana; but as will be gathered from what
follows, the tertiary rocks of the extra-peninsular
regions often contain such shales.
^* In two localities lumps of alum... occur
naturally in sufficient abundance to be a regular
article of export.
"Alum is principally used as a mordant in
dyeing, but as a drug its employment is extensive
in India.
"Behar. Captain Sherwill in 1846 ^ stated
that a small quantity of alum was manufactured
from slates obtained in the district of Shahabad-;
these rocks, it is believed, belonged to the Bijigrah
pyritous shales of the Kaimur group of the Vin^-
dhyan series.
"The alum was sold at the high price of one
rupee per tola ; it was identical with the salajit of
Nepal. Copperas or iron sulphate is obtained in
the same region, which is situated to the north of
Rotasgarh, and to the west of the Sone.

there are manufactories which turn out consider-
able quantities of blue vitriol (copper sulphate),
copperas (iron sulphate), and alum. The process
has been very fully described and illustrated by
Colonel Brooke. In 1864 there were twenty of these
factories at Khetri and about double the number
at Singhana. The broken shale from the mine
which contains the salts is placed in earthen
gharaSy together with the crusts from the refuse
heaps of previous lixiviations and water is added.
The gharas are arranged on ledges prepared for
the purpose on the heaps of refuse, as will be seen
by reference to the wood-cut (vide illustrations) ,
** Each charge of shale is exposed to three
changes of water and the water itself is changed
from one ghara to another till it has taken up the
sulphates from seven different steepings. It is
then of a thick dirty-bluish colour and is taken to
the boiling house, where it is boiled in earthen
gharas ; when sufficiently concentrated it is left to
cool, and thin sticks being introduced the blue
vitriol crystallizes on them. The mother liquor
is then poured off and again boiled, and on the
addition of saltpetre, the alum crystallizes at the
bottom of the vessel. The residual sulphates still
in solution, are allowed to crystallize out by ex-

*' CuTCH. There are numerous accounts of
the manufacture of alum in Cutch, The earliest is
by Captain Mc Murdo, who states that before 18 18
the exports of alum amounted in some years to
several hundred thousand maunds, which chiefly
went to Guzerat and Bombay to be employed in
dyeing. The following account by Mr, Wynne is
the most recent and complete. The site of the
operations is at Mhurr or Madh,
"The rock containing the materials is a pyritous
dark-gray or black shale, which is in close associa-
tion with a soft aluminous pseudo-breccia of the
sub-nummulitic group,
*^This shale is excavated from pits and is expos-
ed for four months, a slow combustion taking place
owing to the decomposition of the pyrites.
" It is then spread in squares resembling salt
pans and sprinkled with water. After about 12
days it consolidates into efflorescing mammillated
crystalline plates or crusts called phitkari-ka-bij or
seed of alum. These crusts are boiled in large
iron vessels (luted inside with lime), together with
saltpetre (or other potash salt), in the proportion
of 15 of 'alum seed* to 6 of the latter ; when it has
ISO* HINDU CHEMISTRY

settled, the liquor is placed in small earthen vessels
somewhat the shape of flower-pots, and crystalliza-
tion takes place in three days. These crystals are
again boiled one or more times to concentrate the
solution, which is finally ladled into large thin
bladder-shaped earthen mutkds or ghards with
small mouth ; these are sunk into the ground to
prevent their breaking, and in five days the alum
is found crystallized in masses. The vessels are
then broken and the alum is stored.
" Alum is also manufactured from the water of
a hot spring north of Mhurr. The impure salt-
petre, which is employed to supply the second
base in the above-mentioned manner, is obtained by
lixiviation of village refuse." (BalFs " Economic
Geology'\ pp. 431-33)-
" Iron Sulphate. The green vitriol or cop-
peras of commerce which is known to the natives
as kahi and hara kdsisy is produced principally from
the so-called alum shales from which alum is pre-
pared. As is the case also with alum, copperas is
found sometimes as a natural exudation upon alum
shales and other rocks which include iron pyrites.
" This native copperas goes by several different
names in India, according to the nature of the
other substances with which it is combined.

Unfortunately very little material is now
available to enable us to present a connected nar-
rative of the metallurgical skill of the ancient
Hindus. Many important links are missing; we
shall here try to put together only a few, which we
have been able te recover.
Megasthenes says that the Indians were " well
skilled in the arts." According to the Greek
writer, the soil too has ** underground numerous
veins of all sorts of metals, for it contains much
gold and silver, and copper and iron in no small
quantity and even tin and other metals, which are
employed in making articles of use and ornament,
as well as the implements and accoutrements ofwar."
Coming to comparatively later times, we find
that the Indians were noted for their skill in the

tempering of steel. The blades of Damascus were
held in high esteem but it was from India that the
Persians and, through them, the Arabs learnt the
secret of the operation/

Delhi which weighs ten tons and is some 1500
years old ; the huge iron girders at Puri ; the orna-
mental gates of Somnath and the 24-ft wrought-

art and bear silent but eloquent testimony to the
marvellous metallurgical skill attained by the
Hindus. Regarding the Kutab pillar, Fergusson
says : *' It has not, however, been yet correctly
ascertained what its age really is. There is an ins-

form of its alphabet, Prinsep ascribed it to the 3rd

to the end of the 5th or beginning of the 6th
century. The truth probably lies between the two.
Our own conviction is that it belongs to one of the

certainly is not far from the truth it opens our eye
to an unsuspected state of affairs to find the
Hindus at that age capable of forging a bar of iron
larger than any that have been forged even, in
Europe up to a very late date, and not frequently
even now. As we find them, however, a few cen-
turies afterwards using bars as long as this lat in
roofing the porch of the temple at Kanaruc, we
must now believe that they were much more
familiar with the use of this metal than they after-
wards became. It is almost equally startling to
find that after an exposure to wind and rain for
fourteen centuries, it is unrusted, and the capital
and inscription are as clear and as sharp now as
when put up fourteen centuries ago.
**There is no mistake about the pillar being of
pure iron. Gen. Cunningham had a bit of it
analysed in India by Dr. Murray, and another por-
tion was analysed in the School of Mines here by
Dr. Percy. Both found it pure malleable iron with-
out any alloy.'' "Hist, of Indian and Eastern
Architecture," p. 508 ; ed 1899.
The Ritter Cecil von Schwarz, who was for
sometime in charge of the Bengal Iron Works
Company, thus speaks of the superior iron smelting
156 HINDU CHEMISTRY
industry in India :
"It is well-known by every manufacturer of
crucible cast-steel how difficult it is sometimes to
get the exact degree of hardness to suit certain
purposes, especially with reference to steel for
cutting the blades, etc., With the ordinary process,
endeavours are made to reach the required degree
of hardness by selecting such raw materials as on
an average have the required contents of carbon in
order to correspond with the required degree of
hardness as far as possible. The natives [of India]
reached this degree by introducing into their cast-
steel an excess of carbon, by taking this excess
gradually away afterwards, by means of the slow
tempering process, having it thus completely in
their power to attain the extact degree by interrup-
ting this de-carbonsing process exactly at the pro-
per time in order to cast steel of a quality exactly
suitable for the purpose."
Zinc
The extraction of zinc from the ores can be

followed in every detail from the account left us
both in *' Rasarwava" and '*Rasaratnasamuchchaya.'*
HINDU CHEMISTRY 15:
yr>^>^^ ^
"Rasaka" is mentioned in Rasarwava as the mine-

ral which turns copper into gold (p. 71). We have
also in the succeeding couplets a process described
for the reduction of the ore. This process is so
elaborately given in R. R. S. that it may be quoted
almost verbatim in any treatise on modern chemis-
try ; it is practically the same as distillation per
descensum the flame of bluish tint issuing from
the mouth of the crucible indicates the combustion
of carbon monoxide, so often observed in metallur-
gical operations/ (See p. 88).
From the time of the Sujruta to that of R. R. S.,
we find all along six metals recognised (see pp. 48
and 127) and the last work distinctly mentions brass
and bell-metal as simply alloys. Owing to the
veneration paid to ancient authorities, the Indian
alchemists had at first some hesitation in classing
"the essence of the lustre of tin ''3i^!^" (p. 71) as
a separate metal. In the medical Lexicon ascribed
to king Madanapala .and written about the year
(i) Cf. "A mixture of 2 parts of ground roasted ore and i
part of coal dust is brought into the retorts, each holding about
40 fts. of the mixture. As soon as the temperature has risen high
enough, the reduction begins and carbon monoxide is evolved and
hums from the end of the clay adapter vAth a blue flame (the italics,
are ours). Roscoe and Schorlemmer's Chemistry, Vol. 11., Pt. i

1374 A. D * zinc is, however, distinctly recognised

as a metal under the designation of Jasada. ^
It it evident rasaka is the cadmia of Dioscorid-
es and Pliny and tutia of the alchemists of the
middle ages. The pseudo-Basil Valentine writing
about 1600 A. D. uses the word zinc but *'he does
not appear to have classed it with the metals
proper." Paracelsus mentions zinc sometimes as a
metal and sometimes as a bastard or semi-metdi,
but it is doubtful whether he had any distinct no-
tion of its true character specially as he says, "it
has no malleability" (keine malleabilitat hat er) or
of the ore which yielded it.* "Libavius was the
first to investigate the properties of zinc more
exactly, although he was not aware that the metal
was derived from the ore known as calamine. He
states that a peculiar kind of tin is found in the
East Indies called Calaem. Some of this was
brought to Holland and came into his hands."
(Roscoe and Schorlemmer).

and tuttha are all applied to calamine, while tuttha
sometimes stands for blue vitriol as well. Some
writers have, however, mistaken kharpara
for blue vitriol, but R. R. S. is very explicit on
this point. The name tutenague by which Chinese
zinc was known in commerce is evidently derived
from the Tamil tatanagam. " In Persian, sulphate of
zinc is called suffed (white) tutia ; sulphate - of
copper, neela (blue) tutia ; and sulphate of iron,
hura (green) tutia \ so, in Avicenna, different
kinds are described under this name, which occurs-
also in Geber " (Royle). Both the Tamil //tt^-
gafn, and the Persian tutia are probably corruptions
of the Sanskrit word tuttham. At the beginning
of the last century the Baron de Sacy was at con-
siderable pains in tracing the history of tutia. In
a note appended to certain extracts from Kazwini,.
the " oriental Pliny," the learned Frenchman gives
the following description . of tutia. The : account
necessarily involves some digressions on the
Aristotelian theory of the formation of dew, hail-
stone, metals, &c., and the reader may with ad-
vantage compare it with that of the Vai^-eshika
-Philosophy. (Chap. I, pp. 1-12).

qui sont le produit des particules aqueuses, par le
nom de vapeures humides ou aqueuses ; et celles
qui doivent leur formation aux molecules terreuses,
par le nom de vapeurs seches ou fuligineuses.
Ce sont ces deux sortes de vapeurs qui forment
au-dessus de la terre les nuês, le vent la pluie
la neige et autres ph^nom^nes semblables ; et dans

des unes et des autres, suivant la diversity de leurs

combinaisons et les diff^rentes proportions dans les-

quelles elles s'unissent, sont produites dans le labora-
toire de la nature un grand nombre de substances
diverses. Suivant ce quôn lit dans les trait^s de phi-
losophie, on ne compte pas plus de cinq esp^ces de
min^raux : ceux qui sont infusibles k cause de
leur s^cheresse, comme le yakout ; ceux qui le sont
k cause de leur humidity, comme le vifargent ;
ceux qui se fondent promptement, mais qui ne sont
ni malleable, ni combustibles, comme le vitriol ;
ceux qui ne sont pas mallâbles, mais qui sont
combustibles, comme le soufre ; ceux enfin qui
sont mallâbles, mais incumbustibles comme Vox.
La fusion d'un corps consiste dans la liquefaction
de ses parties, due k la combinaison de la secheresse
et de rhumidit^: la malleability [ou ductilite] est
la faculty qu*a un crops de receivoir peu k peu une
augmentation d'^tendue, taht en longueur qu'en
largeur, sans separation d'aucune de ses parties
et sans aucune addition.
*' Quand les vapeurs et les exhalaisons se melent
de mani^re que les premieres soient le principe
dominant, et que le melange etant achev^ et la
coction parfaite, Tardeur du soleil coagule cet amal-
game, * le produit est du vif-argent. Comme il n'y
a aucune des molecules de ce produit qui ne ren-

ferme quelque portion d'exhalaison, ce corps a une
quality s^che dont les effets sont sensibles : il rie
s' attache pas k la main ; au contraire, il fuit le
contact : cormme la chaleur a ^t^ le principe de sa
coagulation, la chaleur ne peut la d^truire. Si les
deux principes [les vapeurs et les exhalaisons] se
combinent dans des proportions k-peu-pr^s i^gales^
il se manifeste dans le melange une humidity d'une
nature visqueuse et onctueuse : k I'instant de la
fermentation des particules a^riennes s'insiriuant
dans le melange qiii se coagule alors par le froid,
les produits de cet amalgame sont inflammables.
Si les exhalaisons et la quality onctueuse dotninent,
le produit est du soufre, qui est rouge, jaune, bleu
ou blanc ; s'il y a plus d'exhalaisons et peu de
principe oActueux, Tiamalgame donne Tarsenic qui
est rouge et jaune ; enfin si ce sont les vapeurs
qui .dominent, il se trouve, quand la coagulation
est achev6e, que le produit est de la naphte qui est
noire et blanche. Comme, dans ces amalgames, la
coagulation est produite par le.froid, 'ces corps sont
fusibles par la chaleur : et k cause de Tabondance
de leur quality huileuse et de leur humidity vis-
queuse, ils sont susceptibles de prendre feu ; enfin',
k raison de leur exc^s d'humidit^, ils ne sont point
mallâbles. Les sept corps [ou metaux] ayant

tous pour principes constituans le vif -argent et le

soufre, la vari^t^ de ces corps ne peut avoir pour
cause -que les divers degr^s de puret^ de ces deux
principes, la plusx>u moins gratide perfection de leur
melange, et la diversity d'influence quails exercent
I'un sur Tautre.
^*Si les deux principes ne sont alt^r^s pacr aucun
mflange de parties terreuses, s'ils sont dans toute
leur puret^ naturelle, si enfin ils ^prouvent une
coction parfaite, alors le soufre ^tant blanc et le
vif-argent dans une proportion plus grande, le
produit de Tamalgame est de I'argent ; il est de
I'or, si les deux principes sont dans des proportions
egales, et que le soufre soit rouge et poss^de la
force colorante. Si, les circonstances 6tant les

forme du khat-tchini^ que Ton nomme aussi fer

k ces sept substances le nom de corps ; on appelle le

The term âsyaka as a synonym for blue vitriol

That an essence in the shape of copper is
yielded by blue vitriol is worthy of note from a
historical point of view. Rasarava very often hits
upon it but is not so explicit as R. R. S., as it
modestly contents itself with the mere assertion
that the essence is of the colour of Coccinella insect
i,e. red (see p. 86). In the Bhavaprakaâ (ca.
1556 A.D.) occurs this remarkable passage : T"flW ^

semimetal of copper as it is derived from copper.

Our knowledge of the nature of the " essence '*

From the circumstantial details given above, es-
pecially of the method of preparing the charcoal, one
is naturally led to suspect that the lines relating to
gunpowder as quoted above are later interpolations.
The suspicion is further enhanced when it is borne
in mind that in the Polity of Kamandaki, an ancient
work of undoubted authenticity, there occurs no
reference whatever to firearms nor is there any in
the Agnipura/â in which the subject of training in
the use of arms and armours takes up four chapters,
archery forming the leading element. ^
The more rationtal conclusion would be that
the^yukranlti is a patch work in which portions of
chapter IV were added some time after the intro-
duction of gunpowder in Indian warfare during the
Moslem period.^ Dr. G. Oppert, however, stands up
for its antiquity.

In Sanskrit literature, there are frequent but
vague references to * agni astra" or firearips, but we
have no reason to suppose that the combustible
matter these fire arms contained supplied a motive

The correct rendering should be as follows : " The king sha
not slay his enemies in warfare with deceitful or barbed or poisoned
weapons, nor with any having a blade made red hot by fire or
tipped with burning materials " ; Biihler, who also follows the
above commentators, thus translates : " when he (the king) fights
with his foes in battle, let him not strike with weapons concealed
în wood), nor with ^such as are) barbed, poisoned, or the points of
which are blazing with fire." Whereas Halhed's version is : " the
magistrate shall not make war with any deceitful machine or with
poisoned weapons or with cannon and guns or with any lOther
kind of firearms." .

Mahabharata, Yudhisthira is described as ** collec-
ting large quantities of resin, tow, and other in-
flammable articles, for his great fratricidal war." ^
But there is nothing to show that gunpowder of any
sort was in use or any chemical which would act as
a propelling agent. * ;

is to be found ; thus . we read in Kalhana's Rajatarangini that in

It is very remarkable that in the laler Sanskrit

and in the Rasarava, ceases altogether to be ap-

carbonate of potash, from yava, barley and kshara,

Sanskrit-English Dictionaries, following no doubt
the authority of modern writers, erroneously render
yavakhara as saltpetre as also does Colebrooke in
his **Amarakosha". Roth and Bohtlingk in their
Worterbuch, however, correctly translate it as

It is strange indeed that a substance which
occurs extensively in Bengal and in upper india as

now for saltpetre, now for natron.

probably had no acquaintance with, the old literature on the sub-

taining nitre mention this salt under the name of
"soraka'*. This word; however, is not met with in
any Sanskrit dictionary and is evidently sanskri-
tized from the vernacular sord, a term of foreign
origin. The manufacture of nitre was therefore
most probably introduced into India after the adop-
tion of gunpowder as an implement of warfare." ^

it most ' abounds. It occurs in the salt range between the Indus
and the Jhelum in such quantities that the Greek companions of
Alexander according to Strabo, asserted the supply to be sufficient
for the wants of the whole of India." It would be equally hazar-
dous to rush to the conclusion that nitre was " unknown" to the
Hindus.
(i) Dutt is probably correct in so far as he states his views
with regard to "the manufacture of nitre" as an ingredient of gun-
powder. For it is well known saltpetre has been in use from time
immemorial as the basis of rocket and other fireworks both in
China and India. In the Dasakumaracharita by Dandi, mention
is made of yogavartika (magic wick) and yagachiirna (magic pow-
der), of which saltpetre was probably the basis. The earliest ac-
count of the manufacture of saltpetre on a commercial scale that
we have come across occurs in a rare work entitledc "The Travels
of John Albert de Maiidelso from Persia into the East Indies.
London, 1669." The book is in the valuable collection of my friend,
Mr. Prithvisa Chandra Raya. Says our author :-:-

Mineral Acids.
Geber was up till recently credited with being the
discoverer of nitric acid, aqua regia, silver nitrate &c.
A careful examination of the works of Geber, both
real and pretended, notably of the celebrated Summa
perfect ionis magisterii^ has convinced M. Berthelot
that the knowledge of the mineral acids was un-
known not only to the Arabs but also to the European
alqhemists of the thirteenth century. It was a Latin
author of the latter half of the 13th century who
wrote the above memorable work and assumed the
" Most of the saltpeter which is sold in Guzuratta comes from

Ajmer^ sixty Leagues from Agra, and they get it out of Land that
hath lain long fallow. The blackest and fattest ground yields
most of it, though other Lands afford some, and it is made thus :
they make certain trenches which they fill with their Saltpetrous
Earth, and let into them small Rivulets, as much water as will
serve for its soaking, which may be the more effectually done, they
make use of their feet, treading it till it becomes a Broath. When
the Water hath drawn out all the salt-peter which was in the Earth,
they take the clearest part of it, and dispose it into another Trench,
where it grows thick, and then they boil it like salt, continually
scumming it, and then they put it into earthen pots, wherein the
remainder of the Dregs goes to the bottom ; and. when the water
begins to thicken, they take it out of these pots, to set it a-drying in
the sun, where it grows hard, and is reduced into that form
wherein it is brought into Europe." pp. 66-67.

Such instances of literary forgery are by no
means uncommon in the alchemical literature of the
East and the West.
The distillation of alum is referred to in Rasar-
ava and of green vitriol in R.R.S. (see pp. 71, 92)
We have, however, no evidence that the acid thus
derived was ever used as a solvent. Hoefer justly
remarks that real progress in chemistry was impos-
sible in India and China, as the preparation of
mineral acids was unknown in both these countries.*
At the same time we should remember that Rasar-
ava and similar other works lay stress upon viâ,
in which aqua regia may be said to be potentially
present and which is fitly described as capable of
" killing all the metals '* (see p. 72)
The preparation of mineral acids is incidentally
described in several exclusively medical works,
composed probably in the i6th and 17th centuries,
e. g, **Rasakaumudi" by Madhava, Rasaratnapradipa,
and ^^Bhaishajyaratnavali" by Govindadasa, &c. In

the last -work under the heading of mahadravakarasa,
directions are given for distilling a mixture of,
among other things, alum, green vitriol, salammoniac
saltpetre and borax ii;i a glass retort. In this way
a dilute solution of nitro-muriatic acid is obtained,
which is prescribed in derangement of liver and
spleen. We have a similar recipe in which in
addition- to the above ingredients, rock-salt and
sea-salt are used, thus yielding what is called
"sawkhadravaka" (lit. solvent for conch-shell.)
The term **dravaka^^ (solvent) seems to have been
expressly coined to do duty for the mineral acids.
We have seen all along that in the older works
dravaka was used invariably in the sense of solvent
or flux }(see p. 130) but never in the sense of a
mineral acid, the knowledge of which seems to have
spread both in the East and the West almost simulta-
neously. The regular application of the mineral
acids to technical operations dates from the time of
the Emperor Akbar or perhaps a little earlier. Thus
in the A in-i-A kbari under the ** Method of Refining
Silver " mention is made of the use of rasi (aqua
fortis). It is not easy to make out how much of
the processes of the assay of gold and silver as
described in the Ain is of Hindu origin.

the Hindus were acquainted with the methods of
preparing the mineral acids. These authors who
wrote more than half-a-century ago derived their
information at second-hand as none of them had
probably read the Sankrit works in the original.
Ainslie gives the following recipes as used in
Southern India among the Tamil physicians for the
preparation of sulphuric, nitric and muriatic acids
respectively : ,
Sulphuric acid : ** The Tamil physicians prepared
their article nearly in the same way that we do, viz.^

dak kd attar of the Hindus has long been known
among the Eastern nations. In southern India it
has been prepared for many centuries."
Nitric acid : This acid the Hindus make a
clumsy attempt at preparing in the following man-
ner which must not be rigidly criticised by the
chemists of Europe.

Knowledge of Technical Arts

AND
Decline of Scientific Spirit
In ancient India the useful arts and sciences, as
distinguished from mere handicrafts, were culti-
vated by the higher classes. In the White Yajur-
Veda and in the Taiittiriya Brahma;/a, we meet with
the names of various professions which throw light
on the state of society of that period ; unfortunately
a knowledge of these perished with the institution
of the caste system in its most rigid form. ^ Among
the sixty-four ^'kalas** or arts and sciences which are
enumerated in the old work of Vatsayana * called
Kamasutra occur the names of the following :
(i) See Dutt's " Civilization in Ancient India/' pp. 155-157^

ing its great popularity among our ancestors, which is also clear
from its commentaries and reference by Dandi^ Vamawa and other

the plants is also regarded as a ^'kala."
" The art of alloying and separating the metals

** The art of extracting alkali (see pp. 31-38 under
Sujruta) is likewise counted as a "kala". In the
science of Ayurveda, there are altogether ten
'*kalas^\
i

We also find that among the companions of the

poet Vaa were an assayer and a metallurgist. *
Such terms as **lohavid" and "dhatuvid" which occur
repeatedly in Sanskrit literature show that the
metallurgists were held in high esteem and expert
knowledge sought after.
The art of dyeing was carried almost to
perfection, the fast colours resembling the Tyrean
purple.
In the Vedic age the /?/shis or priests did not form
an exclusive caste of their own but followed differ-
ent professions according to their convenience or
naturs^ tastes, thus fulfilling the ideal laid dowm
by Emerson : "Has he (man) not a calUng in his
character? Each man has his own vocation. The
talent is the call." But all this was changed when
the Brahmins reasserted their supremacy on the
decline or the expulsion of Buddhism.
The caste system was established de novo in
a more rigid form. The drift of Manu and of the
later Purawas is in the direction of glorifying the
priestly class^ which set up most arrogant and out-
rageous pretensions. According to Su^'ruta, the
dissection of dead bodies is a sine qua non to the
student of surgery and this high authority lays par-

is enough to bring contamination to the sacred

after the time of Vagbhaâ, the handling of a lancet
was discouraged and Anatomy and Surgery fell into
disuse and became to all intents and purposes lost
sciences to the Hindus. It was considered equally
undignified to sweat away at the forge like a Cy-

cal explanation of the reactions involved in these lay outside their
circle of interest." Meyer's ** Hist, of Chemistry," trans, by Mc-

Paracelsus flings a sneer at the physicians of his time and com-
pares them with the alchemists in the following terms : "For th(^

velvet garments, often showing their rings upon their fingers or
wearing swords with silver hilts by their sides, or fine and gay
gloves upon their hands, but diligently follow their labours, sweat-
ing whole days and nights by their furnaces. They do not spend
their time abroad for recreations but take delight in their labora-
tory. They wear leather garments with a pouch, and an apron
wherewith they wipe their hands. They put their fingers amongst
coals, into clay, and filth, not into gold rings. They are sooty
and black like smiths and colliers, and do not pride themselves
upon clean and beautiful faces." Quoted by Rodwell in his
" Birth of Chemistry."
Even so late as the middle of the last century, the pursuit of
Chemistry in England was not regarded in a serious light and
" chemists were ashamed to call themselves so because the apothe-
caries had appropriated the name" a circumstance which led
Liebig in 1837 to declare "that England was not the land of

Soldering
The next process that we shall consider is
soldering. This is undoubtedly the most important
process that the goldsmith has to perform, from a
commercial point of view. It is in the course of
this process that the practical goldsmith plays those

mischievous tricks which go so hard against those

who purchase his productions or order for them.
The quality or quantity of solder [or pan) employed
is the first question that is universally enquired into
in all cases of commercial dealings in Indian
jewelry ; and while by melting some articles the
value of the gold per tola is reduced by Re. i or
2 only, we frequently find cases in w^hich the value
is decreased at the ruinous rate of Rs. 8 or Rs. 10.
This last state of affairs arises when the solder
consists almost entirelv of a mixture of baser
metals and is at the same time fraudulently used
in larger quantities than what is absolutely necess-
ary.
Considered, however, from the standpoint of a
chemical student who investigates the subject of
ascertaining the amount of metal that is lost in the
operations of the goldsmith, the process of solder-
ing is scarcely important enough to receive a
separate treatment. The preparation of the solder
and its reduction to the condition] of small thin
bits are embraced in the discussion of melting and
hammering; while the loss during the blowing
operation, during which the reducing flame of an
oil lamp is made to play upon the solder and the
parts it is meant to join together, may be supposed
200 HINDU CHEMISTRY

to have been treated during the discussion of the
subject of loss of gold by volatilisation. The fact
that almost all solders contain a little zinc perhaps
makes the loss in their case to be much greater
than in that of an alloy of gold and copper only.
The following three sets of figures give the weight
of gold and the weight of solder before the process
of soldering and the weight of the article after the
operation has been finished :

Thus, on the whole a loss of iij pies takes
place in dealing with 14J tolas of materials. This
gives the rate of loss at 79 pies per tola.
It is proper to observe that of the loss that
takes place during soldering, about one-third is
due to purely physical causes, e. g. the loss of pieces
of solder which fly off before the blowpipe. The
above figures are accordingly not to be supposed as
affording an accurate estimate of the amount of
material that is lost by vapourisation during the
operation of soldering.

Filing and -Cutting

These are the two operations of the goldsmith
in the course of which gold is lost to an appreciable
extent. The work of cutting is done by a class
of men called nakdshiwalds to whom the articles
are made over for the purpose. In recognition
pf the fact that loss of gold must inevitably take
place during the operation of cutting, the goldsmith,
when he takes back the articles and the particles
that are chopped oflf the surface fr.om the nakdshi-
waldSy generally makes an allowance of one pie per
tola in favour of the latter.
The loss which takes place during the operation
of cutting as well as the loss during filing, i.e.
rubbing the surface of gold with a steel file to make
it smooth, is due to causes of a purely mechanical
nature and can be prevented to a great extent
by the means suggested for minimising such loss
in the course of hammering and drawing.
The operation of cutting is always, and that of
filing some times, effected after the article has been
coloured and polished. But as the chemical pro-
cess of colouring will be treated of separately in the
following pages, the mere mechanical operation

of cutting and filing are here put in for the purpose

The Chemical Operations of the Goldsmith :
Cleansing, Colouring and Polishing
We now come to a process which, though not so
important in the eyes of the goldsmith as some of
the processes before described, is yet of the greatest
consequence in the enquiry in which we are engaged.
This is the process of colouring.
If it were possible for our goldsmiths to work
with pure gold, the appearance of the material
would suffer very little by the various processes
of heating, hammering, &c., and a mere mechanical
rubbing would throw off the superficial dirt and be
sufficient to expose the natural yellow surface of
the unalloyed metal. This property of pure gold
is due to the fact that no oxides of gold are formed
at temperatures to which the metal is exposed
during the operations of the goldsmith. Indeed it
is well-known thst gold does not unite with oxygen
at any temperature.
But the case is different with copper, the oxide
of which is formed at temperatures which are ordi-
narily attained by the goldsmith in the course of
his operations. Hence, if a mass of copper is
HINDU CHEMISTRY 203
heated in the goldsmith's fire, it is divested of its

bright red colour and acquires a dirty black appear-
ance due to the formation of a coating of cupric
oxide. Now, an alloy is nothing but an intimate
mechanical mixture of its constituent metals the
molecules of the several metals lying promiscuosly
as it were. In an alloy of gold accordingly in which
copper forms a constituent part, the particles of the
latter are freely interspersed between those of gold.
When such a substance is heated in air, the gold
particles retain their primitive yellow, but the par-
ticles of copper, which are exposed to air, are
oxidised into CuO. This substance is, as we know,
a black amorphous powder and it gives to the whole
mass a black appearance, which becomes darker
as the metal is hammered over ^nd the powder is
thoroughly spread over the surface of the metal.
An interesting and rather curious experiment
clearly illustrates the above explanation. If a piece
of gold containing a little copper be heated in air
and care be taken not to rub the metal in any way
so as to spread the black oxide of copper over the
surface, it will be found that the metal, if free from
external dirt or soot, will be still yellow and toler-
ably bright. The yellow of the more numerous
gold particles overpowers the colou** of the black
204 HINDU CHEMISTRY

oxide of copper. If, however, this black substance
be spread over the surface of the metal, the colour
instantly changes. The spreading of the oxide
is easily brought about by hammering, and thus we
can take an apparently bright piece of metal and,
by hammering reduce it to a jet black mass.
The ignorant goldsmiths explain this blacken-
ing by supposing the stain of the black steel hammer
to adhere to the surface of gold.
We may, perhaps, in this connection mention
a particular artifice which is sometimes employed
by our goldsmiths to cleanse the surface of a gold
and copper alloy, which has been blackened by fire.
This method is employed whenever it is desirable
in the course of working to expose the bright
surface, but where it would be inconvenient, impos-
sible or unnecessary to apply the long and laborious
mode of cleansing or colouring which we shall
hereafter describe. It is found that if a blackened
piece of gold and copper alloy be heated in a
charcoal fire to redness and then water be sprinkled
on the fire, the alloy at once acquires the bright
colour of gold. This phenomenon, though often
practised by our goldsmiths, is a puzzle to the
most intelligent among them. ^ ^ -x- # * 'pj^^
true explanation of the operation seems to be
HINDU CHEMISTRY -205

that, when placed in a charcoal fire, the cupric
oxide is reduced to metallic copper. But if it is
taken out when hot, it comes into contact with the
air again and is oxidised. What the goldsmith
does is to suddenly cool down the metal when in
the reduced state and not to allow it to coine into
contact with the open airj until it has cooled suffi-
ciently down, so as not to be liable to re-oxidisation.
From what has been stated above, it will be
easily seen that when a piece of golden ornament
has been completed by the manufacturer, it is
of a dirty dark colour and must be cleansed before
it can be used. In this country mere cleansing is
not sufficient, for the popular taste does not ap-
prove the new golden articles appearing and being
used in the yellow colour of true gold. The
articles must be *' coloured" before they can be
made over to the customer,- by which is meant that
a bright reddish colour must be imparted to them.
The particular tinge which is liked by different
persons is different, some people liking a colour
verging very nearly on red or orange, while others
have a fancy for a colour whfch approaches to
reddish violet.
The process of imparting the requisite shade
of colour to articles of gold is one of the most
2o6 HINDU CHEMISTRY
cumbrous and complicated chemical operations

in the whole range of indigenous arts and manufac-
tures of India. The numerous chemical reactions
that take place in the several stages of the business
are of more than ordinary interest ; while the im-
mense loss of gold that apparently takes place leads
one to wonder why the subject has not as yet been
taken up seriously by commercial or scientific men.
The process of colouring, so recently as 20 years
ago, was universally carried out by the goldsmiths
themselves, and in the villages and smaller towns
the state of afairs is still the same. But in the
metropolis and at the bigger stations of the pro-
vince, the advantages of the principle of division of
labour have lately begun to be felt in every branch
of art and manufacture, and the result, so far as this
particular subject is concerned, has been the spring-
ing up of a class of people whose sole business is to
colour ornaments and other articles of gold. These
men are known among our goldsmiths as the
rungwalas. They do not charge any remuneration
for their labour, but retain the fluid in which,
during the process of colouring, a quantity of gold
is dissolved.
We will now follow the rungwala through the
course of a complete set of processes for colouring,
HINDU CHEMISTRY 207
skipping over the mere mechanical parts of the

work, but dealing a little fully with the portions
which are of a chemical nature.
The Processes of the Rungwala
The shop of a Calcutta rungwala is one of the
most miserably furnished working-places in the
whole metropolis. A charcoal fire, a pair of bellows,
a few crude pieces of indigenous earthern-ware,
two pr three coarse pots of China, together with
a few other little things, are all that greet the eager
sight of the observer whom business or curiosity
leads to his dark and ill-ventilated den.
The rungwala has to wait till a suflfiicient num-
ber of golden articles are accumulated in his hands.
He does not generally commence the process until
he has got at least ten tolas of gold for colouring.
Because the cost, the trouble and the time required,
as he says, in going through a complete series of
operations are such as to prohibit his doing the
work with a smaller amount of gold at a time^
Ordinarily a " khola", as the amount of gold colour-
ed at one operation is called, consists of about 20
to 30 tolas of gold.
Having got the amount of gold sufficient for
working a khola, the first thing that the rungwala
2o8 HINDU CHEMISTRY
^^% ^%^%^^H ^% ^ % ^ % ^"k ^\
has to do is to cleanse the articles of all external

dirt as well as of the blackess due to the formation
of CuO. With this view he first heats them in a
charcoal fire, thus causing all the oil, charcoal dust,
and other foreign substances on the surface to burn
off. He next puts an earthen vessel on his fire and
boils in it about a seer of the unripe fruit of tamarind
(Tamarindus Indica), a sustance containing consi-
derable amount of tartaric and other acids in the
free state. Taking out these boiled articles and
squeezing them so as to extract the extremely acid
pulp he forms a thick syrupy fluid. In this fluid he-
boils the articles till the dilate acids dissolve away
the cupric oxide, leaving a yellow surface of pure
gold. It is found that the solution of tamarind pulp
becomes distinctly blue in vitrue of the formation
of copper splits.
In the place of this rather clumy mode of
cleansing, which is largely practised even in the
metropolis, some of the more adventurous rungwa-
las use a rather more clever and neater method.
Instead of preparing a large aniount of tamarind
pulp, they obtain from the grocer's an ounce or two
of a dull white crystalline substance which they
call ''acid,'* and a solution of this serves equally, well,
if not better, for their purpose. ' To the question
HINDU CHEMISTRY 209

as to what the substance called '*acid is, they can-
not give a satisfactory reply. And even the grocer
who sells it cannot enlighten the inquirer more
than to this extent that the article is a gad (scum)
or a bye-product in the manufacture of some acid.
Having subjected the substance to a rough
chemical analysis, we came to to conclusion that
the substance should be nothing more nor less than
KHSO4 or hydric potassic sulphate, an acid salt
and a bye -product, as we know, in the process of
manufacturing nitric acid. The reaction of this
substance on the copper seems to be this :
2 KHSO^H-CuO=K2SO;+CuSO, + H,0.
The normal salt di-potassic sulphate, copper
sulphate and water are formed.
What takes place in the gold as regards the
particles of copper takes place also in the solder
used as regards the particles of both zinc and
copper that are on the surface.
The oxides of copper and zinc are acted on by
the dilute acids of the tamarind or the hydric
potassic sulphate as the case niay be, and are
dissolved away in the form of soluble salts. The
reaction in the latter case is : '
2 KHSO, + ZnO=ZnSO, + K^SO, + H,0.
As the solder contains a large amount of silver^
14
2IO HINDU CHEMISTRY
^V.^-V^S^'S-'-V'-V*
its appearance after the copper and zinc have been

dissolved away, is almost perfectly white, which
appears rather prominent by the side of the bright
yellow surface of gold.
The next operation of the rungwala is perhaps
intended to carry on the operation of cleansing to
a further extent. He takes about half a pound of
common salt, and mixes it with an equal amount of
ordinary potash alum, purchased from the bazar.
The mixture is then reduced to the form of a
line paste. The rungwala now covers each of the
articles to be coloured with a thin layer of this
paste of salt and alum and then places them on the
fire. After the paste has dried up it is washed
off with water, and generally the colour of the
gold appears a little bit improved. The reason of
this lies in the fact that the few particles of cupric
oxide that remain on the surface are not whollv
dissolved out by dilute acid in the first operation
are got rid of by this process.
After having been subjected to these two-
processes, the article acquires almost perfectly the
beautiful yellow of pure gold ; but as has been
stated already the pan or solder appears at the
same time as white as pure silver. The contrast
of these two different colours placed in close con-
HINDU CHEMISTRY 211
X*'''>^.-
^V^ V ^ ^V.^N .*% ^ V^S VX^^^Vr
tiguity is rather marked ; and the next operation

of the rungwala is intended to remedy this defect.
In order to make the solder and the metal appear
of the same colour, he actually covers the surface
of the solder with a layer of gold taken from the
article itself. This is done in the course of the
third process, which we will describe xather fully,
as it is the most important of these stages of mani-
pulation at which loss of gold takes place in con-,
siderable amount.
Having placed an open earthen vessel on his
fire and having put some water in it, the rungwala
prepares a mixture consisting of about four parts
of nitre (say i lb.), one part of common salt and
I part of alum (say \ lb each).^ He then puts the
mixture into the vessel, taking care always that the
water in the vessel be not more than what is necess-
ary for dissolving about half the amount of salts
added. The solution is then heated till it boils
evolving large quantities of gases and fumes,
amongst which chlorine can be easily detected by
its unmistakable corroding odour.
(i) Cf. p. 7J under "kiHing-of mercury and gold," where
a mixture, among other ingredients, of alum, common salt and
saltpetre technically called a vida, is used.
k
212 HINDU CHEMISTRY '
In this boiling solution the goldsmitli places the
cleansed ornaments so as to keep them .wholly im-
mersed. He examines them from time to time. and
after a while finds that a layer of shining gold has
formed on the surface of the white solder. When
this deposit is sufficiently thick and the whole
article presents the appearance of being formed
out of a homogeneous material he takes them out
and, washing them well, prepares them for the next
operation.
Chemical Explanation
It is difficult .to find out exactly the series of
chemical, reactions that take place during this
period. Various impurities in the articles employed
make the inquiry doubly complicated. It would,
however, ,do for our purpose to investigate briefly
the . principal decompositions and formations that
occur, and with this view we may suppose the
reagents employed to be chemically free from
foreign substances.
It is well-known that if nitric and hydrochloric
acids are brought together, certain reactions take
place. If the acids be tolerably concentrated they
act upon one another at ordinary temperatures, the
mixture becoming yellow and giving off minute
HINDU CHEMISTRY 213

bubbks of gas, smelling like chlorine. If "the acids
be dilute, we have to heat the mixture to bring abotit
the chemical change. ' The action that takes place
consists of two of stages :
First, the oxygen from- the nitric acid oxidizes
the hydrogen of the hydrochloric -acid, thus :
HNO, -+- 2HC1=H,0 + HNO, + CI,. . . (i)
Secondly, the - unstable nitrous acid that ' is
formed acts on another molecule of ' HCl, producing
a compound known as nitrosyl chloride and water,
thus :
HNO, + HC1=N0C1 + H,0 . . . (ii)
* The reactions (i) and (ii) when expressed by a
single equation may be-written as follows :
N0,0H+3HC1=N0C1 + 2H,0 + C1, (iii)
Now, here, instead of free nitric arid hydrochloric
acids, we have saturated solutions of a nitrate and
a chloride, and an action similar to the above may
take place under the influence of heat only, instead
of water, the hydrates of the metals present
in the nitrate and ' the chloride are formed. Thus,
instead of equation (iii) we .may have the following
action- :
NO,.OK +3NaCI -f 2H,0 = NOCI + sNaOH-i-
KOH + Cl,.
When the solution boils and these actions set
214 HINDU CHEMISTRY
*.^x ^y^'* ^.-\-
in, the rungwala puts the golden articles in it. The

chlorine liberated as well as the chlorine in the
nytrosyl chloride attacks the gold and reduces it
to the form of a soluble chloride, which mixes with
the mass of the fluid. The NO of the nitrosyl,
which is liberated,' is itself a colourless gas, but it
rapidly unites with the oxygen of the air and forms
the red fumes of nitrogen peroxide which, together
with chlorine, are liberated in large quantities during
the third stage of colouring.
Now we know that if a solution of gold chloride
of sufficient strength is formed and a piece of silver
is dipped into it, gold is deposited on the surface
of the silver, while a portion of the silver is worn
away. The reaction is as follows :
AuCl, +3Ag=3AgCl + Au.
This reaction takes place in connection with the
surface of the solder which is exposed. A layer
of gold is formed upon it entirely hiding the white
surface, so that to all appearance the whole article
seems to be composed of the same material.
In the explanation given above, the use of alum
that is added to make up the jamak (as the solution
employed in the third stage described above is
called) has not been shown, and indeed this point
we have not been able to clear as satisfactorily as
HINDU CHEMISTRY 215

Si f 'l.^^.^ V *^ r'V 1" J'
perhaps it is capable of. ^ It seems to undergo

no chemical change, and hence does not act in the
capacity of a mordant in this case, as it does so
widely in the arts of dyeing or calico printing.
It is also found that if no alum is added to the
jamaky the coating of gold on the solder is pro-
duced, but it adheres very lightly to the surface
and does not stand such processes as rubbing or
brushing. Hence it seems that the only function
of the alum is to fix the coating, i, e. to make it
adhere firmly to the surface of the solder. Expe-
rienced goldsmiths are also of opinion that, but for
the alum, the gilding of the pan would not be
permanent. The way in which this is done by the
alum is to a certain extent a matter of conjecture.
We suppose that the action is of a mere mechanical
nature. When the particles of gold stick to the
surface of the solder, small quantities of alum
solution remain in the pores between the separate
particles. These afterwards dry up and crystallise,
and the minute crystals act as a sort of mortar
(i) Mr. Chakravarti all along fails to realise the important

part which alum plays in yielding sulphuric acid. Moreover in
the above equation chlorine cannot be expected to be set free in
presence of alkalies ; see below under " the Hindu method of
manufacturing calomel."
2i6 HINDU CHEMISTRY
between the particles of gold and the surface of

the solder, as well as between the particles them-
selves.
The third process in the course of colouring
is by far the most important source of lo;5s of gold
in the whole series of manipulations that the metal
has to undergo. We have seen that the losses
at all other stages are due to causes of a mere
mechanical nature and are necessarily small. In
all these cases, the gold escapes the vigilant eye
of the worker and hence the extent to. which it
is lost sight of is minute indeed. Here for the first
time the gold undergoes a chemical change it
ceases to exist as gold altogether and is conse-
quently lost for ever to the illiterate goldsmith.
We should remark that only a very small part
of the gold that is dissolved out in the jamak as
the solution of nitre, alum and . salt used in the
third stage described above is called is re-deposited
on the surface of the solder. A large portion of
the gold remains in the solution as AuCIj. NaCL
2HyP. The helpless rungwala can do nothing
with his valuable fluid but dispose it off for a
trifling sum to a class of men called jamakwalas
who have a crude method of their own to extract
some quantity of the gold from the jamak. We
HINDU CHEMISTRY 217
shall return to the jamakwala subsequently. We

must now. proceed, to the fourth , or last stage of
colouring, , during which the requisite colour is
imparted to the metal. The articles, after being
extracted from the boiling jamak . solution, are
thoroughly washed and rubbed with a brush, after
which another bath is prepared for them. This
consists of a solution, of tamarind pulp, nitre and
common salt in water, which is placed in , an
earthen pot on, fire and heated to ebullition. A
little sulphur is then added after which the articles
are placed in the liquid. The sulphur is added in
a finely divided state, obtained by rubbing a stick
of sulphur with a little water on a piece of slate.
Care is always taken to add an insufficient amount
of sulphur at first, for it is found that the shade, of
colour that is . produced in the . gold . depends solely
on, the quantity, of this ingredient, which according-
ly requires exceedingly carefuly regulation. The
rungwala now . examines the . colour from time to
time, adding more sulphur gradually if .he >wants
the colour to deepen. When the requisite shade
of colour is reached, he stops adding the sulphur
and keeps on boiling for some time more, after
which he takes the articles off the solution and
gives them a final wash and polish. If too much
2i8 HINDU CHEMISTRY

sulphur is added in this operation the colour
becomes deep violet and finally black, and the
whole process is vitiated. Under the circum-
stances the rungwala has to recommence the work
from the very beginning.
It may be noticed that the acid or the commercial
hydric potassic sulphate is never used in this stage,
as it is used in the first, instead of the tamarind
pulp. The reason seems to be that as nitre is also
present in the mixture, the addition of KHSO^, in
the presence of other substances, may result in the
formation of nitric acid under the influence of
heat.
The chemical actions that take place during
the fourth or last stage of colouring seems to be
-extremely difficult of explanation. There can be
little doubt, however, as to the fact that the reddish
violet colour is due to the deposition of a thin
layer of some compound of gold on the surface of
the articles. It is the determination of this
compound and of the exact nature of the process by
which it is formed that presents all the difficulty.
The fact that the sulphur is one of the most
essential things that are required in the production
of the colour would seem strongly to suggest at
the first glance that the reddish violet tint is due
HINDU CHEMISTRY 219
to the formation of one of the sulphides of gold.

It appears that the subject and constitution of the:
compounds of gold and sulphur is one which has
not yet been fully investigated by chemists. But
it seems to be a well-established fact that no sul-
phide of gold is known which is of any other colour
than black. This stands in the way of our accept-
ing the hypothesis that the reddish violet colour
of gold obtained by the Indian goldsmith is due to
the formation of a layer of sulphide oh the surface.
From the fact that if the colouring is allowed to
be overdone i. e. if the articles be boiled further
after the required tint has been obtained, the gold
acquires a deep violet colour, the same conclusion is
arrived at.
Accordingly, in spite of the fact that the amount
of sulphur added regulates the whole operation of
the last stage of colouring, we are constrained to
search for the reddish violet colour that is deve-
loped in the formation of some other compound
than a sulphide. The nature of the colour being
the same as would be produced by a thin layer of
a violet substance on a yellow surface, it follows'
that the colour of the compound formed must be
violet. And the fact that when the colour is
overdone, /. e, when a thick layer of the coloured
A
220 HINDU CHEMISTRY
..-V'vo'^-'X'
substance is formed on the surface, the ap-

pearance of the metal is dark violet, abundantly
confirms the hypothesis. The only compoumd < of
gold that possesses this characteristic colour being
aurous oxide AuÔ, we are forced to the conclu-
sion that the colour of gold is due to the formation
of a thin layer of suboxide on the surface of the
metal.
An examination into the nature of the chemical
actions that take place during, the operation clearly
shows that AuÔ is the compound formed. We
have seen in investigating the chemical changes dur-
ing the third stage of colouring that KNO, and
NaCl being heated together, yield free chlorine
together with KOH and NaOH. This chlorine
after being liberated in the fourth stage attacks the
gold and a small amount of auric chloride is formed.
But at this point sulphur is added, and the nascent
chlorine, instead of going to attack the gold any
more, combines with the sulphur to form one or more
of the sulphur chlorides. The supply of fresh chlo-
rine being thus cut off, the heated auric chloride
decomposes into aurous chloride and chlorine. The
chlorine thus liberated combines with the sulphur,^
while the aurous chloride is acted on by the
KOH and NaOH with the result that Au,0 is

^V^^rf-^j^V
formi^d/ This is partly deposited oil the surface

of the gold producing the required colour and
partly mixed with the saline solid matter preseirit
in the solution.
The series of chemical reactions may be express-
ed by formula as follows : -
(i) KN03 + 3NaCl4-2H,0 = NOCl + 3NaOH +
KOH + Clg 1 this reaction itself consists of two
stages as explained before.
(2) 3Cl+Au = AuCl3.
(3) 2Cl + S'2:=S2Cl2 (SClg may also be formed
in the precence of excess of nascent chlorine).
(4) AuCl3 = AuCl + Cl,
(5) 2 AuCl + 2K0H = Au,0 + 2KCl + H,0.
It will be observed from the above formula that
the addition of sulphur is indispensable in this
operation If the excess of chlorine were not re-
moved by sulphur, as is done in (3) above, the gold
would continue to be dissolved out and a large loss
of the metal would arise as in the course of the
third stage.
Moreover, with a free supply of chlorine, the
auric chloride would never be reduced toaurous chlo-'.
(i) The explanation is scarcely satisfactory ; it may be taken
for what it is worth-

ride, and thus no formation of aurou^ oxide could

take place. It is thus seen that, though the sulphur
used is not directly contained in the compound
which gives the colour, it regulates the whole reac-
tion in the most important stages of its progress.
The above hypothesis is supported by the fact
that if a little sulphur is added to the fluid obtained
in the fourth stage of colouring, it will be found to
disslove in the fluid. This could not be the case
unless a compound like S^Cl^, which can hold sul-
phur in solution, were formed during the re-action.
It has been mentioned above that the loss dur-
ing the third operation of colouring is considerable.
Indeed, from the records of observation given at the
end of this section, it is clear that the loss is not
only large, but that its extent is also uncertain in
the extreme. In some cases it is as low as half
a pie per tola, while in others it reaches the
ruinous figure of six pies per tola, or nearly one
tenth of the whole weight. The average amount
of 2^ pies per tola, which is obtained from our
figures, is not very different from the idea of expe-
rienced rungwalas and goldsmiths on the subject.
The largeness and uncertainty of loss are easily
accounted for by the ever-varying constitution of
the bazar articles used in the operation, some of

them being very nearly pure, while others contain

as much as 35 to 30 per cent of impurities, as. well
as by the want of any accurate precision as regards
the proportion of materials employed. The ingredi-
ents are seldom weighed before being mixed toge-^
ther ; and the varying amount of water present
physically in the salts is an additional source of error
and confusion in settling the proportion by mere
inspection of bulk.

The Restorative Processes

Having in the previous paragraphs described
with tolerable fulness the various sources of loss of
gold in the course of its artistic manipulation by the
Indian goldsmith and having in each case pointed
out the form in which the metal escapes the hold of
the worker, we will now turn our eyes to the meth-
224 HINDU CHEMISTRY

ods which now obtain in our country for recovering,
as far as possible, the amount of material which is
lost. It is perhaps worth while here to point out
that to re-obtain the entire amount of lost material
is absolutely impossible from the innate property
of the (extreme divisibility of matter ; and oiir sole
object in these restorative operations should be to se-
cure the recovering of the largest amount of metal
that can possibly be saved. There are two small
classes of men in Bengal who obtain their living by
extracting gold from the refuse and bye-products of
the goldsmith's workshop. These are the nehar-
wala and the jamakwala before alluded to. These
classes of men are found to cluster in the suburbs of
large towns and important centres of jewelry manu-
factures. In the smaller towns and more insignifi-
cant villages, the bye -products have either to be
thrown away or to be disposed of in the best man-
ner that the goldsmith can hit upon. Not unfre-
quently in such cases the goldsmith himself under-
takes to play the part of a jamakwala and nehar^
wala to the best of his abilities. But the unpractised
manipulation of prbcesises, which are themselves far
from being satisfactory is sure to result always
in the loss of a large portion of gold.
We will now proceed to describe the operations
HINDU CHEMISTRY 225

of the neharwala and the jamakwala. It may,
however, be marked here that the immense diffi-
culty in the way of obtaining the slightest informa-
tion regarding the indigenous methods adopted by
these workmen, in the exercise of their profession,
can hardly be appreciated by one who has not per-
sonally made an attempt to penetrate into the mys-
teries of any of the trade or manufacturing secrets
of India. The unfortunate stagnation of almost all
departments of knowledge, art and industry in
India that perplexes and mortifies an inquirer, owes
its origin to a longstanding and universal spirit of
conservatism inherent in our people which, however
eloquently defended by orthodox advocates of caste,
is manifestly one of the principal causes why the
Indian craftsman lags so far behind in the modern
race of nations. The healthy broadness of views,
resulting from the dissemination of liberal English
ideas among the masses, has, indeed, broken some
of the most pernicious strongholds of the intellec-
tual monopolies of India ; but there are classes of
men who still in obscure nooks of society keep to
themselves what they regard as the treasures of
professional secrets but what, after all, may be
mere child^s play to the eyes of the scientific
world.

To our enquiries about the nature of the nehar^

wala and the jamakwala the deafest ears were turn-
ed. Our attempts to impress upon these people the
necessity of the application of chemistry to improve
their methods were mere cries in the wilderness.
And it was not until we had spent several weeks in
constant intercourse with these people that we
could begin to collect the information necessary for
such an inquiry. Bit by bit we gained from differ-
ent sources some knowledge of the processes
which are given below in a continuous and well-
arranged form.
The Neharwala
Now and then the neharwala makes his appear-
ance in the goldsmith's workshop, in order to
obtain the collected sweepings and other refuse
of the rooms, The interval of time varies from
one to three months according to the nature of the
work that carried on in the rooms as well as
to the amount of gold that is manufactured into
ornaments. It is useful to state here that every
day before work is commenced, the room is swept
very clean and the sweepings, instead of being
thrown away, are carefully stored up in a corner.
HINDU CHEMISTRY 227

\^^*\^\'
The heap of dust and rubbish thus accumulated

from day to day is the chief object of the visit of the
neharwala. Having inquired as to the amount of
gold that has undergone manipulation since the last
disposal of sweepings or nehar (from this the nehar-
wala gets his name) as well as the nature of the
articles that were manufactured, he proceeds to
settle the price which depends chiefly on these
conditions. The nehar of twenty tolas of good
gold manufactured into articles, which required draw-
ing, beating as well as soldering would generally
be disposed of for a single rupee. It may be
interesting to observe that a goldsmith, however
dishonest in other respects, would never deceive a
neharwala by selling to him a heap of ordinary
rubbish for fear of losing credit and custom in the
department of nehar -selling.
The next thing that the neharwala wants to
obtain is the heap of rejected crucibles.
It has been stated before that indigenous cruci-
bles cannot be employed more than once for melting
purposes, and hence the number of waste crucibles
is not small in our goldsmith's workshop. The
nature of the crucibles and the amount of metal
melted in each, together with the qualities of the
gold, settle the price. We have seen a score of
228 HINDU CHEMISTRY
^v^x-* j-y^-\^
crucibles of average size selling for eight annas.

If the goldsmith's shop is large, the soot hanging
from the ceiling and walls is also purchased.
The last thing that the neharwala asks the
shopkeeper is whether that day he would give a
taljhar^ by which is meant if he would allow the
workmen's mats to be removed and shaken and
the space below the mats swcpl. This operauuii
is ordinarily perfomed once a year. The sweepings
thus obtained are again valued. And after paying"
the prices the neharwala returns home with his
heavy load, which sometimes reaches the respecta-
ble weight of 50 or 60 pounds.
The first thing that the neharwala does with his
materials is to crush them fine. This is only
necessary when earthen lumps of large size are
formed and mixed up with the nehar in consider-
able numbers and is dispensed with in most cases
where the large pieces are few in number and can
be picked up and thrown away.
The second process is to throw the curshed
materials into a big earthen pot in which the nehar
remains immersed in water for a certain number of
days, depending on the quality and quantity of the
nehar. The object of this is to reduce fragments
of clay to a fine state of division by which particles
HINDU CHEMISTRY 229
of gold that might otherwise remain imbedded

inside the mass of earthy lumps are at once ex-
posed to view.
The next and the main operation is that of
working. The thoroughly soaked nehar is put in
large earthen vessels and more water is added if
necessary. The mass is then thoroughly stirred
and the lighter earthy material which yet floats
when the heavy metallic matter has settled in the
bottom, is taken off. By the repetition of this
process the solid matter is reduced to a very small
bulk. It is then allowed to settle and the water is
slowly poured off. The moisture that yet remains
is dried up either on fire or in the sun.
When several nehars have been separately
Avashed in the preceding way, the remnants of all
the washings are mixed together and the mixture
in washed once again. This operation is exactly
like the preceding but is carried on more care-
fully and in better vessels. When it has been
completed, about one-quarter of the mixture may
be perceived to consist of metallic substances.
Among the metals present in this mixture, iron
is often found and, as its presence is extremely
undesirable when the meterials are placed on the
crucible for melting, it is generally got rid of at this
i
230 HINDU CHEMISTRY
X- ^ ^ -^.^V ^%yN,jx''
stage. Formerly this was done by picking up the

separate bits of iron by fine pincers, but now-
a-days the magnet is almost universally used for
the purpose.
The next process is that of melting. This is
carried on in the ordinary way, care being taken to
procure a crucible big enough for the purpose.
The earthy matter sticks to the sides of the cruci-
ble, while the metallic portion melts and falls to the
bottom. A mixture of gold, silver, copper and
zinc is thus obtained.
The old method of obtaining pure gold from
such a mixture as this is said to have been as curious
and interesting as certainly it was laborious and
protracted. The alloy was first of all beaten into
leaves of extreme thinness, about 5 inches square
in size. Each leaf was then covered with a thin
layer of a paste of brick dust and common salt.
The leaves were finally arranged one above another
and exposed to the heat of fire. After a certain
number of days, depending on the nature of the
alloy and the temperature of the fire, the gold was
found to be very nearly pure.
This method has now, however^ been entirely
superseded by the far easier and more economical
process of treating the alloy with strong nitric acid.
HINDU CHEMISTRY 23J

For this purpose, however, the metal must be
obtained in a fine state of division. This is done
rather ingeniously by melting the material and,
while molten, by suddenly dropping it in water.
By this means the metal is at once reduced to a
fine powder without the expenditure of any manual
labour in the way of hammering. Care, however,
should always be taken to see that the vessel of
water in which the molten metal is dropped has a
wide mouth. On one occasion, at which we were
present, the liquid metal was poured into a narrow-
mouthed vessel, and the steam suddenly generated
was so great and powerful as to very nearly cause
an explosion.
The extraction of gold from rejected crucibles
is done much in the same fashion. These are
pulverised and treated in the same way as ordinary
nehar. Sometimes the powders of crucibles are
mixed up with the common nehar to avoid the
necessity of a separate series of operations, but
more frequently the smallness of their bulk induces
the neharwala to treat them separately.
The Jamakwala
We will now turn our attention to the methods
oi the jamakwala. He periodically visits the work-
232 HINDU CHEMISTRY

shops of his patron , the rungwala from whom he
obtains the necessary amount of jamak on the
payment of a price which depends on the quality
and the quantity of gold that has been coloured,
as well as the loss of weight that has taken place
in the articles during their make. To give an
approximate idea of the commercial value of jamak
it may suffice to state that we once purchased
a jamak of 20 tolas of sovereign gold (which is
22 carats or 91 6*66 per mille fine) for one rupee
only. We may also observe that the demand of
jamak is not at present at par with the amount
of its supply ; and at some of the bigger rungwala* s
working-rooms, one may see big earthen jars full
of this substance, collected and stored up for want
of purchasers. It may be interesting to add that
even in this obscure department of business, the
evil genius of man has set to work, and one has
to be careful in dealing with a jamakwala, if one
is a new hand in these affairs.* On one occasion
we happened to be defrauded and were given a
substance as a jamak of 35 tolas of gold for what
(i) It may be observed, however, that a rungwala would
never deceive a jamakwala in the same way as he would deceive
a stranger for fear of losing credit and custom in the department
of jamak-selling.
HINDU CHEMISTRY 233
^V/*^*- J-X*
we considered the modest price of Rs. 2. But

the thing turned out to be an imitation jamak
only and all our best efforts could not discover
in it the slightest trace of gold.
Having obtained a sufficient amount of this
fluid the jamakwala returns home. His first step
is to get rid of the fluid part of the jamak by
boiling it. For this purpose he has got large
earthen vessels with wide mouths which can be
placed over a fire. When almost the whole amount
of water has been evaporated off, he pours out
the viscous mass into an open eathern vessel and
porceeds to what we shall call the second process
of the jamakwala.
With the solid matter of the jamak obtained
by the first operation, the jamakwala mixes a
small quantity of borax as well as a large amount
of a substance known as poonoor. The weight
of powdered poonoor that is thus added is about
four times the weight of the jamak matter. Having
thoroughly mixed -these- substances - with such an
amount of cow-dung as is required to give consis-
tency to the material, he forms them into balls
of about* two or three inches in diameter. He then
dries these balls and when perfectly dried they
are ready for the third process.
234 HINDU CHEMISTRY
^^^^10^ ^f *'^^^ ^^%î
Th^ poonoor employed in the above process is

a hard quasimetallic substance that can be purchased
from certain grocers at the rate of three or four
seers per rupee. It is, they say, nothing but a
bye-product in the operation of rupd-pdicdno by
which is meant the operation of chemically purify-
ing silver which has been alloyed with a large
amount of copper and other metals. The usual
method of conducting this operation in our country
is to mix up the alloy with a large amount of lead
and after melting the whole mass to blow air
from above. [This operation, as also the next one,
is practically that of cupellation] . The pure silver, it
is found, separates in the course of the operation
and collects at the bottom, while the partially oxi-
dised lead, together with the impurities which
existed originally in the silver constitutes the poo-
noor of trade. We analysed qualitatively a sample
of ordinary bazar poonoor by the wet way after dis-
solving it in nitric acid and found it to contain lead,
copper and zinc with traces of silver and iron.
The third process of the jamakwala is the main
step in the reduction of gold. He scoops out on
the earth in an open place a hollow of the shape of a
hemisphere about a foot in diameter, and having
thoroughly smoothed the interior of this hollow, he
HINDU CHEMISTRY 235
covers it with a layer of slaked lime about half an

inch thick. After the lime has dried, it presents
the appearance of a cou'*se white china vessel, im-
bedded in the earth. In this the balls prepared
by the second process are placed. The jamak--
wala then forms a powerful charcoal fire over it
and with two or three large pairs of bellows causes
the flame to play on the mass below. The lead
of the poonoor is soon reduced and dissolves,,
as it were, the reduced gold, silver and copper.
A large metallic mass thus collects at the bottom
of the hollow, consisting mainly of lead. The
blowing*is now continued as hard as possible from
above and the metal being oxidised to litharge
begins to be blown off. The process must be con-
tinued till the whole of the lead has passed off and
a mixture of gold, silver and copper remains behind.
Care should always be taken in this operation to
see that the last trace of lead is thoroughly got rid
of ; for nothing affects so much the ductility and
malleability virtues most important for the pur-
poses of the goldsmith of gold as a mixture ever
so little of lead. Thus '* one two-thousandth part
renders the metal too brittle for rolling and its
very fumes produce a serious effect upon it.'

236 HINDU CHEMISTRY
Such is the tedious length and such the labo-

rious and complicated nature of the processes by
which the neharwala and the jamakwala extract
precious metal from the large heaps of rejected
sweepings and dirt and bye-products of the gold-'
smith\s workshop. But their labours have only
the empirical experience of years to guide them
and not the acuteness of a well trained scientific
mind ; and accordingly we find that a large portion
of their work is directed to achieve in a laborious
and round-about way an object which a slight
knowledge of chemistry enables us to secure in
the simplest manner imaginable.
With a view to shorten the labours of the jamak^
-wala as far as possible, we began a series of
experiments, investigating the properties of the
jamak and trying to find out the easiest mode of
extracting gold therefrom. As the results of our
experiments we have found that, working on ordi-
nary plans in the wet way, we can recover an
amount of gold, which is. equal to, if not in all cases
greater than, the quantity which the jamkawala
can obtain by his expensive and protracted
methods.
We need scarcely give the properties and the
<ônstituents of the various specimens of jamak
HINDU CHEMISTRY 237

which we obtained from the bazar from time to time
for experimental purposes. The way in which a
jatnak is formed having been before described
in full, the results of analyses will be nothing but
tedious. It will be sufficient to observe that in all
cases the jatnak was a clear greenish-yellow
liquid of rather thick consistency with a large
mass of grey solid matter at the bottom consisting
almost wholly of soluble saline matter.
It may be also added that, among bases, silver,,
copper, zinc, gold, aluminium, potassium and sodium
were the principal ones that were found ; while
amongst the acids present, nitric, sulphuric and
hydrochloric were recognised in large quantities.
Traces of free chlorine could also be found in some
of the solution, while perceptible amounts of iron
were found in almost all.
The microscopic appearance of jatnak may be
interesting as showing the exact state in which
gold exists in the solution. With this view we
examined under a miscroscope (magnfying 375
times) a drop of a clear solution of jatnak as well
as an amount of the solid saline matter lying at the
bottom. The appearance, in both cases was the
the same, only in the latter the crystals were
more numerous and closer together. The octahedra
238 HINDU CHEMISTRY

of alum with occasional facets of cubes, the long
furrowed and rhombic prisms of nitre and the cubes
of common salt were very prominent. Between
these, in numbers far less, could be discovered long,
transparent needles. These were most probably
crystals of double chloride of gold and sodium which
is invariably formed when a solution of auric chlo-
ride is mixed with chloride of sodium. The consti-
tution of this substance is AuCl,. NaCl + 2Hfiy and
it is the commercial " non-deliquescent chloride of
gold*' which is ordinarily sold in one gramme tubes.
Besides the above crystals, we frequently found
amorphous particles, wholly or partially opaque.
Those that did not transmit light at all were proba-
bly particles of dust or other earthy matter which
were present in the ingredients in the shape of
impurities. But there were others which transmitted
a beautiful * green light and these were likely to be
fine particles of gold. As these were rather few in
number, it might be inferred that in the jamaky gold
-existed chiefly in combination. It is also probable
that the greatest part exists as NaAuCl4 + 2H20.
From a liquid containing such a variety of subs-
tances in solution as the jamak does, it is no doubt
a difficult task to precipitate the gold which is
present perhaps in the minutest quantity of all.
HINDU CHEMISTRY 239
^>^^^% * ^V>^*^ r"* ^~XV^*^N^-%,^^
The reducing agents that are mentioned by che-

mists as suited for reducing gold from solutions
are exceedingly numerous. Of those that are prac-
tically employed, the pricipal ones are ferrous
sulphate, oxalic acid, sulphurous acid metallic iron.
We tried each of these in a large number of
cases and found that ferrous sulphate gives the
best result of all. The reaction that takes place
during reduction by ferrous sulphate is sometihng
like the following :
2AuCl, + 6FeS0^= 2Au + 2Fe, (SOJ, + Fej^CLg.
The gold is precipitated as a fine, heavy, black
powder and easily settles at the bottom.
At first we used the pure material obtained
from the chemists for precipitating jamak; but
afterwards ifound that the crude article of the bazar,
after being dissolved in water and filtered, yields
a solution which serves equally well.
This makes the process a niatter of very little
expense and with an anna worth of good crystals of
hirakash (the Bengali name of ferrous sulphate), a
jamak containing 8 annas weight (for about Rs.
14 worth) of gold can be satisfactorily extracted*
We are far from thinking that in our experi-
mental attempts to extract gold, we were able to
catch the whole of the material that was present
240 HINDU CHEMISTRY
>^"v^--f"<i
in the solution. It is very probable that in the

fine state of division, in which the precipitation
takes place, a considerable amount of the metal
is washed away in the process of collection. But
this loss is due to causes of a mere physical nature
and can be prevented to a large extent by the
use of better and more refined instruments.
It has, however, been ascertained that even
with rough instruments the easy and inexpensive
mode of wet working gives as good results as
the laborious and costly method of the jamakwala.
The indigenous worker thinks himself fortunate if
the amount of gold which he extracts is of twice
the value of the jamak from which it is obtained*
and we are convinced from the results of repeated
experiments that the wet method promises in gen-
eral no less than twice the amount of profit with
the advantage of saving time, labour and expense.
Conclusion
The importance of the subject that has been
described and discussed in the major portion
of the preceding pages is far greater than it
appears to be at the outset. Month after months
in Calcutta and in the larger towns of Bengal^
"Considerable quantities of gold undergo transforma-
HINDU CHEMISTRY 241

tion under the goldsmith's hammer; and as every
article so manufactured is coloured before being
used, the amount of jamak that is produced must
be large indeed. By a rough calculation we have
estimated that about 3500 persons earn their bread
in Calcutta by following the occupation of a manu-
facturing Jeweller; and allowing for holidays,
illness and want of work it may be safely held
that about 2,000 hammers ply on an average
every day on gold and silver within the bounda-
ries of Calcutta and its suburbs. Out of these
2,000 hands 1,500 may be supposed to work
on the more precious metal of gold alone. On
the modest calculation that a man works one-half
of a tola of gold in the course of a day, 750 tolas
of golden articles are turned out every day in the
metropolis. Supposing as we have pointed out
before that in colouring only one-half of an anna
of weight of gold is dissolved out into the jamak
per tola^ as much as 375 annas or more than 23
tolas of gold are every day dissolved in Calcutta
alone. As has been shown before, we have ample
reasons to believe that the jamakwala can seldom
get out as much as one-half the amount of gold
that exists in the jamak by his crude and imperfect
methods. Granting, however, that he can reclaim
16
242 HINDU CHEMISTRY
so much as two-thirds of the gold lost in colouring,

we are still forced to the astonishing conclusion
that seven tolas of gold are absolutely lost in the
town of Calcutta alone with the lapse of each day.
There can be little doubt that if the whole
of the jamak that is now thrown away or otherwise
washed could be collected and worked on the
lines suggested by the newest and the most refined
chemical methods, no less than three fourths
of the entire loss could be reclaimed. This would
amount to some thing like 15 or 16 lakhs of rupees
per annum in these hard days of struggle for
existence.
This is not the place for giving even the
outlines of any elaborate scheme by which the
collection of jamak and the extraction of gold
therefrom may be carried out in practice on an
extensive scale.
Business may be commenced at once by setting
up a laboratory fitted up for the purpose after
the latest fashion, at a convenient station in the
centre of the Province and by purchasing the
jamak that has already accumulated in the hands
of the rungwala. In the meanwhile agencies may
be established in every district for the purchase
and storage of jamak. When the accumulated

-%_/>. ^
jamak is all exhausted, these agencies will be able

to feed the laboratory continually by the supply
of fresh jamak from time to time, from all parts
of the country.
Note on the Salts. '
Romaka, also called .Sakambari, is the salt
produced from the Sambar Lake near Ajmere
(Dutt).
Sauvarchala : see under saltpetre.
Audbhida (lit. begot of the soil) is the name
applied to the saline deposit commonly known as
the reh efflorescence. It consists ^^chiefly of
sodium chloride and sulphate in varying propor-
tions. In addition there are sometimes carbonate
of soda, and we have usually found some magnesian
sulphate. In certain localities the last named salt is
in very considerable proportion. In other cases
nitrate of lime or alkali is present.^^
*'The efflorescences thus produced consist of
three groups; ist, the neutral, which contain no
carbonate of soda (these consist chiefly of
sodiûm chloride and sulphate, and frequently
magnesium sulphate) ; 2nd, the alkaline chloride^
and sulphates, but no lime or magnesian salt ; 3rd,
the nitrous efflorescences.'^ Dr. Center's Note on

Products of India". Vol. VI. Part I. pp. 410-417.
We have thus a ready explanation of the
conversion of mercury and other metals into their
chlorides when they were heated in combination
with audvida and other salts (see p. 48). The
magnesium sulphate would readily yield sulphuric
acid, which with sodium chloride and nitre, might
be expected to produce aqua regia ; (for further in-
formation see under "rasakarpura*' or the chlorides
of mercury).
Virfa or Vit is at present taken to be the same
substance as the kalanimak or '' black salt ^* ; it is
difficult to ascertain what it stood for at the time of
the Charaka and the Sujruta. The following
account is given in Watt's Dictionary of the Eco-
nomic Products of India. "Black Salt is pre-
pared in upper India chiefly at Bhewani in the
Hissar district by heating together in a large ear-
then pot 821!) of common salt, one pound of the
fruit of Terminalia chehuluy and one pound of
Phyllanthus emhlica, and one pound of sajji (im-
pure carbonate of soda), until by fusion of the salt
the ingredients are well mixed, when the , pot is
removed from the fire and its contents allowed to
cool and form a hard cellular mass. This prepa-
HINDU CHEMISTRY 245

ration is used medicinally principally as a diges-
tive/^ The salt has a reddish brown colour and
consists mainly of sodium chloride with traces of
sodium sulphate, alumina, magnesia, ferric oxid^
and sulphide of iron. Most of the samples, we
have examined, were found to evolve minute quan-
tities of sulphuretted hydrogen when treated with
an acid ; even when placed in the mouth the taste
of this gas was distinctly felt. It is very probable
that when the saline mass is fused with the organic
matter [T. chebula], a portion of the sodium sul-
phate is reduced to sulphide, which by double
decomposition converts the traces of iron salt
present into the sulphide. The sulphide was
detected both in the insoluble residue (as FeS) as
well as in the aqueous extract.
In the Chemistry of Bubacar, the following salts
are mentioned :

It will be seen, however, that the last 3 or 4

placed under the ksharas or the alkalies (p. 45).
Note on the Killing of Metals
From the time of the Charaka and the Suj^ruta
we find metallic preparations in the shape of
oxides, sulphides and sometimes chlorides recom-
mended for internal administration. The various
formulas, which will be found scatttered throughout
above, give us methods for killing the metals. '
But a killed metal is not necessarily a compound ;
it sometimes means a metal deprived of its wêll
characterised physical properties, e.g. colour, lustre
&c. Thus the Ayurvedic killed gold and silver
often represent the respective metals in a fine state
of division. Take for instance the following

mercury (/. e, sulphide of mercury) and sublime the
mixture in a closed crucible. On repeating the
process 8 times, the gold is killed/' (Cf. also the
processes described in pp. 105-106). In the prepa-
ration of " makaradhvaja *' (p. 132, note) the gold,
which is left behind, would be regarded in the
same light. As the Hindu latro-chemists were
very particular about the killing of the metafe
being ensured, they had often to hit upon* proper
tests for securing this purpose. Thus " Rasaratna-*
kara ** says : '^'In order to examine whether the
mercury has been completely reduced to ashes, it
has to be heated over a gentle fire for 3 hours.
If the weight remains constant, know then that
it has been completely killed.*' In other
words it means that if there be any free
mercury present, it would volatilise oflf and thus
there would be a loss ip weight. In page ii8
will also be found some tests for killed iron.
The language of a portion of couplets 25-28 is
somewhat obscure and the meaning seems to be
the very reverse of what the context would suggest ;
** killed iron is that which, on being mixed with
treacle,... >. honey and heated^ docs not revert to

probably conveys M^j/tf/^ in whichit originally was

speaks of the resurrection of the dead (p. 120).
Indeed, the ideas of the alchemists of the East
and the West ran so closely on parallel lines that
the best commentary we can oflfer to the above
is the following extract from Hoefer's work, des-
crihing the notions current among the old Eg)'p-
tinas.

Other "experiences** as well as technical terms
have also their exact analogues in the language of
the Western alchemists. Thus side by side with
the "tests for killed mercury'* (p. 74) and the "pro-
cess for the fixation of mercury*' (p. 131) we may
quote :

The passage in Rasar;2ava describing the effi-
cacy of the apparatus especially the line "without
the use of herbs and drugs mercury can be killed
with the aid of an apparatus alone** (p. 67.) is highly
significant. It refers no doubt to the formation of
the red oxide of mercury, the precipitate per se.

On THE Hindu Method of Manufacturing
Calomel ; The Hindu and Japanese
Methods Compared The Expla-
nation OF THE Reactions involved
According to the Hindu alchemists, there ate
four kinds of the ash [bhasma) of mercury, namely
black {kajjaliy p. 61), red (vemilion), white and
yellow. * The white variety is often spoken of as
rasakapiira or camphor of mercury ; it is often
found to be almost pure calomel and sometimes a
mixture in indefinite proportion3 of calomel and
corrosive sublimate.
The chlorides of mercury are found to be medi-
cinally used from the 12th century downwards and
various recipes are given for their preparation.
The earliest account seems to occur in Rasarwava
(ch. XI. 24), where we find a mixture among other
dfugs of green vitriol, alum and salt, described as
(i) fi'iHH^, KWH^T. or ^'Bf^'^'c: ; âww and ^f^^^

capable of '^killing mercury in an instant" (see p.

73)* A more detailed description is found in
"Rasendrachintamawi'* a work which may safely be
placed in the 13th- 14th century. Says the author
Dhundhukanatha : ''I am now going to explain the
process of preparing rasakarpura, which is a reme-
dy for all diseases : take a strong earthen pot and
fill one-fourth of it with common salt and place over
it a mixture of brick-dust, alum and rock-salt. Rub
mercury with the juice of Indian aloe and an equal
weight of the above mixture into a paste ; deposit
it in the earthen pot and cover it with the same in-
gredients. The pot is to be firmly closed with a
well-fitting lid. Now apply heat for three days
together." '

Another work of the latro-chemical period,
^' Rasendrasarasamgraha'' describes the following
process for obtaining the svetabhasma or white
ash. '*Rub mercury repeatedly with paiTisu salt
(f . e, audbhida salt : see p. 243) and the juice of Eu-
phorbia ncriifolia ; place the mixture inside an iron
bottle, the mouth of which is closed with a piece of
chalk. The bottle is embedded in a mass of salt
(cf. the salt-bath. p. 123) and then fire is urged for
an entire day. The white deposit in the neck of
the bottle is to be collected." ^
The BhavaprakiLra written about 1500 A. D.
prescribes calomel in the treatment of Phiranga^
roga (lit. the disease of the Portuguese /. e. syphi-
lis) and gives the following recipe : "Take of puri-
fied mercury, gair'iKa (red-ochre), brick-dust, chalk,

are opened, and the white camphor-like deposit in
the upper part is colleeted for use. *' ^

254 HINDU CHEMISTRY
The Japanese method has been described by

Professor Divers at length ' and a summary of it is
given below in the eminent chemist's own words : r
''The Japanese prepare calomel pure, above all
things from corrosive sublimate. They heat balls
of porous earth and salt soaked in bittern along
with mercury, in iron pots lined with earth. The
heat forms hydrochloric acid from the magnesium
chloride in the bittern, and the mercury sublimes
into the close-fitting but unattached clay covers
of the pots. Air enters by diffusion and oxygen
and hydrochloric' acid gas act together in the
hollow cover on the vapour given off from the
sublimate of mecury there formed."
It will be seen that the process somewhat appro-
aches that of " Rasendrasarasawgraha" in which the
pa;su salt, which contains magnesium sulphate
(see p. 252) sets free hydrochloric acid. The
recipe of *'Rasendrachintamai" and Bhavaprakara
would seem to have their analogue in the Chinese
method, for a short account of which we are also
indebted to Professor Divers' Memoir :
The translation from *' Bhayaprakisa " as given above is by

Dutt.

HINDU CHEMISTRY 255
S<'X''V*V*'X
'* The Chinese process, if correctly described y

differs from that used in Japan in several material
points, one . of which is that the mercury is inti*
mately ground up with the other materials, and one
fails to see what reaction can take place between
it and the two others, namely salt and alum.
Heated, the mixture must give off mercury and
hydrochloric acid,and then these, as in the Japanese
process, will with air give the calomel, but this is
independent of the previous intimate mixture of
the mercury with the salt and the alum. Another
point is that in place of the magnesium chloride
of sea-water as the source af hydrochloric acid, the
Chinese are said to use alum or copperas, which,
with the salt, will react to give hydrochloric acid.
A third point is that the cover is said to be
closely luted to the iron pot, which must nearly
exclude the air, without which it is impossble to
explain the formation of calomel. Perhaps this
is the reason why the Chinese process is said to
take four or five hours' firing, since this may
give time enough for the needed oxygen to diffuse
through the cup and luting, it will also account
for the fact, if it is one, that the yield of calomel
is markedly less in weight than the mercury
used.*'
256 HINDU CHEMISTRY
The Chinese and Hindu methods * are essen-

tially the same as in both alum plays an important
part in that it yields sulphuric acid. Professor
Divers in his explanation of the Japanese method
supports the view that the hydrochloric acid at first
liberated undergoes aerial oxidation, thus : 2HCI +
0=H^0 + Clj ; and it is the chlorine thus set free,
which attacks the mercury, forming calomel â
view which has been accepted by no less an authority
than Mendelêflf. * The author has all along en-
tertained doubts as to the correctness of Divers'
hypothesis and he has, in his lectures, pointed out to
his students that some " catalytic agent'' as in Dea-
con's process must account for the reaction involved.
This now turns out to be so. It is the ferric
( I ) To which may be added that of the Latin Geber :

" Argentum vivum sic sublima. Sume de eo libram unam,
vitrioli nibificati libras duas,aluminis rochae calcinati libram unam,
et salis communis libram semis, et salis petrae quartam partem,

which really acts as; the chlorinating agent, Jf
-we may so call it, in that it combines with thie
hydrochloric acid forming ferric chloride, and the
latter in turn dissociates into ferrous chloride and
free chlorine.
The alumina of the clay also plays a similar
part. A series of experiments were undertaken
to establish this point, the results of which are
stated below :-^
I. Mercury, intimately rubbed with moiat
magnesium chloride, was gently heated in a
combustion tube in a current of carbonic acid
gas : globules of . mercury and hydrochloric acid
condenised in the cooler parts of the tube, but
ho calomel was formed.

(ferric oxide), was treated exactly as above â
crystalline sublimate of calomel was at once ob-
tained, mth only a faint trace of corrosive subli-
mate. There was very little free mercury left.
III. The experiment under ii was repeated,
only alumina being substituted for ferric oxide
almqst chcailcally pure calomel was obtained, the
yield being rather less.
IV. Mercury, was vapourised in a current of
air mixed with hydrochloric acid gas calomel was
formed, but the yield was proportionately very
much less than in i ; by far the largest amount
of mercury volatilised as such and condensed
in the cooler parts of the tube as globules. *
The formation of calomel as in exp. IV. is, in
itself, an interesting reaction and it is rather surpri-
sing that Roscoe and Schorlemmer's latest edition

trator, Chemical Dept., Presidency College, with whom he has,

Process. It was Mr. Bhaduri who hit on the true explanation
as given above. The experiments i, ii, iii and iv were all performed

the subject in all its bearings, we can confidently look forward

note of it. Our contention, however, is that the
traces of air that would diffuse through the porous
lid would give rise to a quantity of calomel
which may almost be regarded as negligible. For
the true explanation, as we have already pointed
out, we should look to the presence of ferric oxide.
Our view receives additional support from the
fact that the residue in exp. 11. was found to con-
tain ferrous chloride.
The Chinese method as also that of the Latin
Geber recommends the addition of saltpetre as
thereby more of corrosive sublimate would be
formed than calomel, and this purpose is equally
served in the process of Bhavaprakaya which uses,
over and above brick-dust, gairika (red ferrugi-
nous earth, see p. 139, thus further increasing the
chlorinating capacity. Professor Divers is of opinion
that the sulphuric acid set free by alum acts upon
sodium chloride giving rise to hydrochloric iacid
(loc. cit). and does nothing more ; our view is that
the sulphuric acid simultaneously acts in a two-fold
capacity; first, it liberates hydrochloric acid; second-
ly, it acts upon mercury forming mercurous or
mercuric sulphate as the case may be and then
double decomposition takes place between the
two. thus:
36o HINDU CHEMISTRY

HgaSO,-h2HCl=Hg,CI, + H,SO^
The sulphuric acid in turn acts opon a fresh
quantity of sodium chloride and mercury and so on.
By far the larger portion of the chlorides of mercury
would seem, however, to be formed through the
agency of the ferric oxide.
The processes, of ** Rasendrachintamai '' and
" Bhavaprakaya'* were also put to an experimental
test, the globules of mercury were broken up by
being rubbed continuously with a mixture of brick-
dust, alum and common salt, and the mass was
transferred to a stout . bottle, which was wrapped
in several folds of cloth, smeared with clay *.
The bottle was embedded in sand and heated for
3 hours ' vide illustration. The sublimate that
was obtained was a mixture of calomel and
mercuric chloride ; in one experiment brick-dust
(i) The experiments were conducted under the author's

personal supervision .by Kavir&j Prakrttiprasanna Kaviratna,
who is well skilled in the Hindu methods of killing metals.
(2) The heating for 3 or 4 days together as recommended
in the Hindu piethod need not be taken seriously, indeed it ûst
be regarded as an extravaganza of the old alchemists. Professor
Divers in applying his theory of tgrial oxidation tq the Qhlnese
process has been led to suppose . that it "takes 4 or .5 hours'
firing, since this may give time enough for the needed oxygen
to uiiTuse through the cup and luting."

was omitted and the product was pure calomel ^.
There was necessarily some loss of mercury by
volatilisation in these cases and the yield was
short of the theoretical quantity. It will be seen
that common salt, with alum or green vitriol, is
quite competent to " convert mercury into calomel ;
but the addition of brick-dust increases * the
chlorinating capacity, giviiig rise to a certain pro-
portion of corrosive sublimate, which can probably
be avoided by gentle heating as in the Japanese
method.

Five samples, procured from the market and
prepared according to the indigenous method,
when exhausted with water gave in the filtrate
only faint brown coloration with sulphuretted

free from corrosive sublimate.
Dutt, we are afraid, derived much of his information on
chemical subjects from hearsay. By "subliming the black
sulphide of mercury with common salt/* we got, as we expected,
merely cinnabar. The sodium chloride was simply left behind.

of the first.

Rust of iron
(Mandara, p. iii)
Hindu physicians generally procure the scales
from the black-smith's forge, which peel off the
red-hot bars of iron, when they are struck on the
anvil with an iron hammer. These are subjected
to further roasting, sometimes as many as 500
times and powdered very fine.
Sample I
The powder was reddish brown in colour ; and
slightly magnetic ; 0*6638 g was boiled a few hours
with hydrochloric acid in a current of carbonic
acid gas. On adding a drop of potassium
ferricyanide solution to a drop of the iron solution,
a faint blue colour was noticed. Weight of insolu-.
ble residue, which was simply siliceous matter,
was equal to o'loyg ; the oxide of iron was therefore
equal to o*6638g o'io7g.=o*5568g. The solution,
distinctly yellow in colour, was treated with
ammonia and the precipitate, ignited in the usual
Way, weighed 0560 g. The sample was thus
practically ferric oxide (Fe^ b,).
Sample II.
264 HINDU CHEMISTRY
It was magnetic and of dark iron colour;
0'259g, digested as above with hydrochloric acid,
gave as residue (sand &c.) 0*131 g, Wt. of the
real oxide=i28g. The solution was treated with
ammonia and the precipitate, ignited as usual,
weighed 0'i30g. The latter was once more
dissolved in HCl and tested with K, Fe Cy^ ; but
no indication of ^ferrous salt was obtained. It is
thus evident that both the samples contained onfy
a triace of ferrous oxide.
As a check upon the above analyses, black
scales were procured from a smith's and examined.
These were carefully sifted by means of an electro-
magnet and freed from dust and other foreign
impurities. 0*622 g scales was heated in a plati-
num crucible over a blow-pipe flame and cooled
at intervals, till the weight was constant at o'649g.
Now Fe O. Fe^ O, thus becomes Fe O3/2. Fe,
O, or 232g 24og
Now 0622 X g=o'643g
232
, The difference between the theoretical amount
and that actually found is thus only 6 milligrams.
This is no doubt due to the scales enclosing
minute traces of metallic iron.

. In the Hindu method of killing and purifying
metals, the juices expressed from various plants
are frequently used (cf. pp. 61, 132). The ashes
of plants rich in potash are also utilised as a
source of alkali. (Cf. pp. 35-36). We give below
one or two typical analyses.

analysis failed to indicate the presence of any
principle of special interest. No alkaloidal body
was detected, and the alcoholic extract contained
no principle reacting with ferric salts.

and leaves were separately examined with the
