Mr. Babcock continues:--"Human comprehension is inadequate to grasp the possibilities of this discovery for power, for increased prosperity, and for peace. It includes all that relates mechanically to travel, manufacture, mining, engineering, and warfare." Up to within two years, Keely, this discoverer of unknown laws of nature, has been left partially to the mercy of men who were interested only in mechanical "possibilities." In the autumn of 1888, he was led into a line of research which made the mechanical question one of secondary interest; and yet the present results are such as to prove that on this line alone can he ever hope to attain commercial success. The course then adopted has also been the means of placing his discoveries before the world, endorsed in such a manner as to command attention to his views and theories. It has been said that if extreme vicissitudes of belief on the part of men of science are evidences of uncertainty, it may be affirmed that of all kinds of knowledge none is more uncertain than science. The only hope for science is more science, says Drummond. Keely now bestows the only hope for science--"more science." He accounts for the non-recognition by scientists of his claims, in these words: "The system of arranging introductory etheric impulses by compound chords set by differential harmonies, is one that the world of science has never recognized, simply because the struggles of physicists, combating with the solution of the conditions governing the fourth order of matter, have been in a direction thoroughly antagonistic, and opposite to a right one. It is true that luminosity has been induced by chemical antagonism, and, in my mind, this ought to have been a stepping-stone towards a more perfect condition than was accepted by them; but independent of what might be necessary to its analysis, the bare truth remains that the conditions were isolated--robbed of their most vital essentials--by not having the medium of etheric vibration associated with them." In order to subdivide the atoms in the atomic triplet, the molecular ether, liberated from the molecule, is absolutely necessary to effect the rupture of the atoms; and so on, progressively, in each order of ether, molecular, inter-molecular, atomic, inter-atomic, etheric, inter-etheric, the ether liberated in each successive division is essential to the next subdivision. The keynote of Mr. Keely's researches is that the movements of elastic elements are rhythmical, and before he had reached his present stage in producing vibrations, on the principle of resonance, he has had problems to solve which needed the full measure of inspiration or apperception that he has received.
