These secretions, though imperfectly performed, might, with as much stric... more »tness of induction, be attributed to the unexcited irritability of the limb, to which power secretion in general may always independently be owing; subject to the wholesome excitations, which, in a state of health, are conveyed through the nerves. Besides, it is certainly creating a division of labor, which may appear unnecessary, to assign the muscular action of the stomach to the muscular power, and its function of secretion to the nerves, which are distributed to it; and with much deference to the deductions, which have been made by Dr. Philip, I am induced to consider, that his very ample experiments are quite as confirmatory of secretion being made to depend, in either the living or the recently dead animal, on the irritability of the organ or its muscular power, as they are of its dependence on the nervous influence. This influence, in life, appears to be the natural stimulus, and the nervous cords the channel of further stimulation, or of direct sedative influence; as galvanism proves to be an artificial stimulus to the muscular power, that may yet remain, to different extents, in the recently dead animal. Leaving, however, at present the labors and analysis of this extensive inquirer to that high respect, to which they are entitled, and wishing to refrain from overstepping the strict boundary, prescribed in the outset of this short essay, for the indulgence of any curiousspeculation into the manner, by which this principle of automatic or organic life is at first produced, and from time to time generated ; I shall also desist from speculating on the exact part or time, in which the food is at first endued with t...« less
