Professor Gompertz therefore concludes that “the true meaning of those statements should therefore be expressed as follows: ‘In all substance of mixed colors at least the kind of atoms which lends them their specific taste is merely the predominant and preponderant kind, and without wasting more words on this subject, Theophrastus, who is our best authority for Democritus’ theory of sensation, relates that this doctrine was expressly taught by him’.”[14] FOOTNOTES: [Footnote 6: Zeller, Dr. Edward, “Pre-Socratic Philosophy,” Vol I.

Democritus could, possibly, on his theory, have arrived at such an explanation; whereas Aristotle, on his theory of the elements, could not possibly have done so--any more than could Empedocles (495-436 B. C.) have done so with his “four elements.” As for the primal substance (“air”) of Anaximines (588-54 B. C.) and the “fire” of Heraclitus (535-475 B. C.), Dr. Gompertz contends that these were implicitly recognized as being composed of “minute, imperceptible particles” (“Greek Thinkers”, Vol. I, Page 323).] [Footnote 11: “On the Properties of Matter under High Pressure.” Annual Report of the Smithsonian Institution, 1918.] [Footnote 12: Morgan, Professor C.
