EV. Frequently; but many impostors have withstood the test, and triumphed in their deception. Yet it is true that the perfect state of catalepsy has been, in very rare instances, voluntarily produced; thus exhibiting the complete influence of will over an _involuntary muscle, the heart_. The case of Colonel Townsend I adduce, as one of undoubted authority. This officer was able to suspend the action both of his heart and lungs, after which he became motionless, icy cold, and rigid,—a glassy film overspreading his eyes. As there was no breathing, there was no vapour _apparent_ on the glass, when held to his mouth. During the many hours in which this voluntary trance existed, there was a total absence of consciousness, yet a _faculty of self-reanimation_! Avicenna speaks of one that could “cast himself into a palsie when he list;” and Celsus, of a priest that could “separate himself from his senses when he list, and lie like a dead man, void of life and sense.” Cardan, the Pavian astrologer, brags of himself that _he_ could do as much, and that “when he list.” Dr. Cleghorn, of Glasgow, relates the case of a man who could stop the pulse at his wrist, and reduce himself to the condition of syncope, _by his will_, of course. Barton, the holy maid of Kent, was enabled thus to “absorb her faculties.” Restitutus, a presbyter, could also throw himself into a trance,—being insensible, except to the very loudest sounds. So says Augustin. ASTR. So that there may not be much imposture in the case, recorded in the “Spectator,” of Nicholas Hart, a professor of somnolency, who _lived by sleeping_. The following is his advertisement in the “Daily Courant,” of that time:— “Nicholas Hart, who slept last year in Saint Bartholomew’s Hospital, intends to sleep this year at the ‘Cock and Bottle,’ in Little Britain.” I will freely confess to you, Evelyn, my scepticism as to these _ultra_ romantic legends; but may my own memory fail me not, while I relate a few strange stories, and demand of yourself confirmation. Euphemia Lindsay, of Forfarshire, slept eight weeks, having taken nothing but (possibly) a little cold water. In the eighth week she died. Angelica Vlies, of Delft, had fasted in a state of insensibility from 1822 to 1828. She took nothing but water, tea, and whey, and these in the most minute quantities. In a record, A.D. 1545, I read that “William Foxley, a pot-maker to the Mint in London, slept in the Tower of London (not being by any means to be waked) fourteen days and fifteen nights; and, when he waked, it seemed to him that the interval was but as one night.” Samuel Clinton, of Timbury, near Bath, often slept for a month; and once, from April to August. He would, during this period, suddenly wake, but ere food could be administered to him, he lapsed again into a trance.
