This system is as much a work of evolution as is any one of the slow operations of nature. "Truth can afford to wait:" she knows that the Creator of all things never hurries. In these twenty years of toil Keely's patient perseverance has been godlike. It is the sharpest rebuke that could be uttered to those whose impatient "hue and cry" has been, "Give us a commercial engine and we will immortalize you;"--grinding from him, meantime, seven-eighths of his interests in his inventions. But in his labours Keely finds a recompense that, as yet, "the world knows not of;" for day by day he sees the once, to him, obscure domain lit up with ever-increasing glory; a domain the boundaries of which are the boundaries of the universe: the entrance into which promises the fulfilment of the hopes of those who look forward to "a time when we shall no longer go to the blind to lead the blind in our search to make life worth living; but, instead, be able to promote, in accordance with scientific method and in harmony with law, the physical, intellectual and moral evolution of our race." As of Newton, with the change of one word only, so one day will it be said of Keely:-- All intellectual eye--our solar round First gazing through, he by the blended power Of laws etheric, universal, saw The whole in silent harmony revolve. What were his raptures then! How pure! How strong! And what the triumphs of old Greece and Rome With his compared? When Nature and her laws Stood all disclosed to him, and open laid Their every hidden glory to his view. On the 23rd of March, following the reading of this address, Professor Koenig, who had become deeply interested in Mr. Keely's researches, wrote:-- "With regard to the experiments, which I saw at Mr. Keely's, I venture upon the following suggestion, as a test of the nature of the force Mr. Keely is dealing with. The revolution of the compass as a result of negative polar attraction. It is stated in Mr. Keely's paper that he finds gold, silver, platinum, to be excellent media for the transmission of these triple currents. Now it is well known that these same metals are most diamagnetic, that is, unaffected by magnetic influences. If, therefore, a needle be made of one of these metals and suspended in place of the steel needle, in the compass, and put under the influence of Mr. Keely's force, it ought to revolve the same as the steel needle will under magnetic and polar and anti-polar influence. If Mr. Keely could make such a needle revolve, it would convince me that he is dealing with a force unknown to physicists." To this requirement Mr. Keely replied: "To run a needle, composed of non-magnetic material, by polar and depolar action is a matter of as infinite impossibility as would be the raising of a heavy weight from the bottom of a well by sucking a vacuum in it, or the inhalation of water into the lungs instead of air, to sustain life."
