The cow and goat voluntarily de-electrise the cud, for medium of space to enter and press it upwards through the food-passage which the cud presses against, instead of being raised by nerves or muscles of the esophagus. In parturition also, and the discharge of the feces, the same principles are maintained. The "throes of Nature" are consequent on the natural pressure being made intermitting, by electric matter returning to and escaping from the birth at intervals. The physiologist may refer to muscular action; but where are the delivery muscles? The stage-dancer makes de-electrising efforts to receive medium of space, by which to be lifted above the boards and supported a few seconds in the air. Muscles at full stretch in opposite directions, and the fulcrum, if any, being carried by them, is out of all dynamic rule. All persons make a de-electrising effort previous to the leap-spring, and while continuing to stand or run and tiptoe, without being aware of the reason; and the fatigue is not muscular, but in keeping the body fittingly de-electrised. The _gymnotus electricus_ kills the distant prey instantaneously, which receives nothing whatever of missile from the enemy; nor could the latter be accessary to the death-stroke, were there nothing between to connect one with the other: nothing passing and no connecting means, no outstretched arm or instrument touching that which is to be acted on, is a mechanical absurdity, and is attributing an effect to that which, it may be said, is an absent cause. The eel voluntarily performs the cerebral operation on the electric matter which is continuous from itself through the air to the marked prey, which effects instantaneous removal of the same matter from the prey; which permits medium of space at the same instant to give the de-electrised part the death-blow. APPLICATION OF MESMERISM. First. A National Asylum, to be named, THE BRITISH MESMERIC INSTITUTION, should be founded and endowed. England should take the lead. A Professorship of Magnetism should be founded. All Sanatory Asylums to be obliged to furnish their experience periodically, and be under control of the Institution, which should be possessed of power to undiploma the medical practitioner who refuses to mesmerise. Self-mesmerising to Clairvoyance, to be taught, which is as teachable as ventriloquism; the principle is the same of both,--the theory is that of sound.
