   • 1832, Letitia Elizabeth Landon, Heath's Book of Beauty, 1833, The Knife, page 145:

     Suddenly roused from the state of stupefaction to which fear had reduced her, the female filled the air with shrieks. Disengaging herself from the officers, and rushing towards her husband, she clung with all her strength to his arm, imploring him, with frantic violence, not to let them kill her.
