[198] This system has been formulated with great talent by M. Emile Saigey, who advocated it, first in several very remarkable articles in the Revue des Deux Mondes; and afterward in his book, La Physique Moderne. Essai sur l'Unité des Phénomènes Naturels.
[199] The swiftness of molecules and the vibratory motion of ethereal atoms are astonishing, and surpass all imagination. The former, measuring two thousand metres, give eight millions of collisions in a second; while the latter, within the same space, produce every second several hundreds of millions more of undulations.

[201] According to the very curious experiments of M. Hirn, the unity of heat or caloric in man, as well as in inorganic matter, corresponds to four hundred and twenty-five unities of mechanical labor—that is to say, to four hundred and twenty-five kilogrammes raised one metre high. Man gives in work twelve per cent of the heat produced, which is almost equal to the labor of our most perfect machines.
