"In Keely's early struggles, somewhere about twenty years ago, I became acquainted with him, and helped him then to the best of my ability. Indeed I may say that I was god-father to his discovery; for I was with him when the idea first entered his head that he could combine steam and water to run an engine. At that time he made a crude machine, which he actually ran for some time; and this was the original model of the Pneumatic-Pulsating-Vacuo-Engine, in the operation of which he discovered his present force. From that day to this he has been in pursuit of some method as a medium to use what he calls his etheric force with. That he has actually discovered a new force there is not a shadow of doubt. In those days I have known him to sell and pawn everything of value in his house to obtain means to continue his investigations with the money thus acquired; and I am sure that he will eventually give to the world the greatest boon that has been received by it since the advent of Christianity," etc., etc. It has been very generally thought that Keely is pursuing the ignis fatuus of perpetual motion. No greater mistake could have been made. The genuineness of his claims as a discoverer rests upon a correct answer to the question, "Is hydrogen gas an element or a compound?" Science, as Herodotus said, is to know things truly: but science tells us that hydrogen is a simple, that the atom is not divisible, and that latent energy is not locked in the interstitial spaces of all forms of matter from their birth or aggregation. Keely's system of Vibratory Physics refutes these canons of science. How absurd must seem the idea to many that the schools can be wrong, and that Keely, who has been branded by some of these schools as an impostor, should be right: but time will show whether Keely's discoveries have "come to stay." The history of the past shows us that science has never been infallible; that like Christianity she unfolds her truths progressively. Keely teaches that an unknown potency is held in the atom's tenacious grasp, until released by an introductory impulse given by a certain order of vibration, depending upon the mass-chord of the aggregation; which impulse so increases the oscillation of the atoms as to rupture their etheric capsules. All great truths hold germs potential of ever-increasing growth. It took half a century for the "Principia" of Newton to overcome the contempt that was showered upon it; and now progressive science is overshadowing Newton's vast attainments. In his giant mind was born the hypothesis that the ether is the cause of light and gravity. Keely has been teaching for years, that ether is the medium of all force. For every effect science requires an efficient cause. Hence, when Faraday found no definite knowledge in exact sciences to satisfy him on certain points he was led into speculative science, or the preliminary reaching after truths which we feel must exist by reason of certain effects that come under
