So the old scientists used to believe; but later students have held that it was only a force, caused by vibration. Now, according to a writer in the London Electrician of March 21, electricity is material, a substance, "identical with ordinary matter, the electric unit, or 'electron,' being nothing but a tiny chip separated from an atom of any elementary substance," as the Literary Digest of June 28 expresses it. The writer in the Electrician expresses it: "The generation of 'electricity' consists in splitting off an electron from the atom. The electron then produces a stress in the ether similar to that due to a 'negatively' charged body. The remainder of the atom acts as a 'positively' charged body, tho we do not know as yet whether the positive charge is due to a special positive electron or not." After much interesting information he continues: "We have at last discovered what we may call the 'electric substance.' We can weigh it, and measure it, and produce it in any quantity. It may yet prove to be the 'protyle' of the philosophers—the fundamental and primordial substance of the universe. The 'electric charge' is now no longer a mere phantasm of the mathematician. It is a solid reality; as solid, at least, as a deal table." Now there may be ground for this. It may be hypothesis, like the present generally-accepted theory of etheric vibration. If true, it may help souls to believe what is actual verity whether this hypothesis be true or not, that spiritual beings are not immaterial but substantial, and that in heaven we "have a better and an enduring substance."
