Now, although, if taken by themselves, such experiments could not be regarded as _conclusive_ in favor of the electric nature of vegetable vitality, notwithstanding that this theory best explains the phenomena; yet, when considered in connection with the fact that the nervous fluid of the animal kingdom is evidently a modification of electricity, and probably constitutes the vital force of the animal, the theory of its identification, under another modification, with the vital principle in the vegetable kingdom also, as deduced from experiments like those just adverted to, receives strong confirmation, and is now, I believe, being adopted by many of the best philosophers of the age. EXTENT OF ELECTRIC AGENCY. When we have settled upon the position that the electricity of the heavens and of the artificial machine are identical, and that their identity is essentially one with galvanism, magnetism, the electro-vital fluid of animal and the life-force of the vegetable kingdoms, it requires no extravagant imagination, nor remarkable degree of enthusiastic credulity, to suppose that all the forms of physical attraction and repulsion are due, under God, to the diversified modifications of the same all-pervading agent--ELECTRICITY. Indeed, for myself, I feel no hesitation in expressing it as my belief that electricity, in one phase or another, and controlled only by WILL, is the grand motive-power of the universe. I believe that, in the form of electro-vital fluid, the great Creator employs it as His immediate agent to carry on all the functions of animal life; and that, in respect to voluntary functions, He subordinates it as a servant to the will of the creature, to effect such cerebral action and such muscular contractions as are demanded by the creature's volitions. I am disposed to think that, by the omnipotent power of His will, He controls and uses electricity, in its various modifications, as the immediate moving-force by which He accomplishes all the changes in the physical universe. It is fast becoming a generally-received opinion among modern _savans_, that every body in nature is really magnetic, more or less; and that all visible or sensible changes are but the result of changing poles. Chemical affinities and revulsions are believed to be only the more delicate forms of electrical attraction and repulsion; the ultimate particles of matter, no less than matter in masses, being subject to the control of electrical laws. The imponderable agents, light and caloric, under the ingenious tests of scientific scrutiny, are beginning to give some very decided indications of being simply electric phenomena. Indeed, the doctrine or theory that supposes caloric to be simply _atomic motion_ is even now being very generally accepted by the scientific world. And that motion in the atoms of a body which causes in us the sensation of heat is probably electric motion. And permit me to
