The Corpuscles seem to possess the same Mass--to carry the same charge of Electricity--to act precisely the same--irrespective of their source. No difference in size, mass or character, as in the case of the Atom--all are identical, save in the rate of their vibration at the time of observation, which is simply a matter of more or less Motion. Space seems to be flooded with these tiny particles--these Units of Substance. They stream from the Sun; the Stars; and every body highly heated. Likewise they stream from the bodies of highly electrified Substance. Groups of these Corpuscles, absolutely identical in nature, size, mass, etc., constitute the Atoms of the Seventy-five Elements, the "kind" of Element seemingly being dependent upon the number and arrangement of the Corpuscles, and possibly by their rate of vibration. Every Atom is like a great bee-hive with a swarm of Corpuscles vibrating, moving around each other, and upon their own centres. And, if by the action of intense heat, transmitted, or caused by interrupted Motion--or if by a strong Electric charge--some of these Corpuscles are detached from the Atoms (or possibly an Atom broken up), they fly off through Space at a marvellous speed of many thousand miles an hour. So we see that these wonderful Corpuscles look very much like Primal Matter or Ultimate Substance--the "Stuff" out of which Substance is made. And, taking you back to the chapter on "The Universality of Life and Mind," the writer would remind you that in their Motions and evident Attraction, etc., these Corpuscles evidence the same "Life and Mind" that we observed in the Molecules and Atoms. It must be so, for what is in the manufactured article must be in the material of which the article is made. And so, even here, Life and Mind have not escaped us. Nor will it in The Ether! And speaking of the Corpuscles, as "manufactured articles," we are reminded of Herschel's thought about the Atoms, when they were regarded as Primal Matter and likely to be uniform, and, at the end, of one primal substance. Although Herschel's conception does not now apply to the Atoms, it may be transferred to the Corpuscles. Herschel thought that the fact that the Particles of Substance were likely to be found to be uniform in size, and identical in nature and characteristics, indicated that they might be akin to "manufactured articles," turned out from the same great machinery of Creation. This idea would indicate that the Creator applied the rules of careful manufacture to the manufacture of the Particles, the uniformity operating in the direction of (1) Economy of Material; (2) Utility through interchangeability, replacing broken or discarded parts, etc.; and also (3) Conformity to a Standard of Size, Quality, etc.
