concourse of four triple atoms, a quaternary atom; and so on, to a gross, grosser, or grossest mass of earth: thus great earth is produced; and in like manner, great water from aqueous atoms; great light, from luminous; and great air, from ærial. The qualities that belong to the effect are those which appertained to the integrant part, or primary particle, as its material cause; and conversely, the qualities which belong to the cause are found in the effect.
"The dissolution of substances proceeds inversely. In the integrant parts of an aggregate substance resulting from composition, as in the potsherds of an earthen jar action is induced by pressure attended with velocity, or by simple pressure. Disjunction ensues; whereby the union, which was the cause of incohation of members, is annulled; and the integral substance, consisting of those members, is resolved into its parts,
"There seems to be a high degree of probability in the assumption that Empedocles and Aristotle did not themselves deduce their theory of the elements, but derived it from other sources; thus the oldest writings of India teach that the world consists of the four elements mentioned above, together with ether, which last is most likely related to Aristotle's o'uvía—Meyer's "Hist. of Chem".
