Mr. Keely has chosen the successor [20] of Professor Tyndall, at the Royal Institution of Great Britain, as the physicist to whom he will communicate his method. This will be welcome news indeed to scientists on both sides of the Atlantic, and the result will be awaited with anxiety alike by both the friends and foes of Keely. We shall watch for the result, as will our American confrères.--Wm. Norman Brown. CHAPTER XVII. 1891. MORE OF KEELY'S THEORIES.--HIS TRADUCERS EXPOSED. It was in India that man first recognized the fact that force is indestructible and eternal. This implies ideas more or less distinct of that which we now term its correlation and conservation. The changes which we witness are in its distribution.--Professor Draper. "For all things that be not true, be lies." There is a principle in music which has yet to be discovered.--Sir John Herschel. From the Chicago Tribune. That was a happy inspiration which led the Quintet Club, of Philadelphia, to pay a visit to the workshop of Keely a few weeks ago. Its members had been told that the illustrious inventor had employed the power of music to develop the wonderful forces of nature, and evolve by a law of sympathetic vibrations a mighty energy through the disintegration of a few drops of water. Naturally they were anxious to go. They were familiar with the claim made by Paganini that he could throw down a building if he knew the chord of the mass of masonry, and wanted to know if it were possible that the dream of the great violinist is realized at last. So nearly as can be made out from the mysterious language of the man of many promises, there is a harmony of the universe that is controllable by the strains of music. Each of the molecules composing a mass of matter is in a state of incessant oscillation, and these movements can be so much changed by means of musical vibration that the matter will be disintegrated, its constituent molecules fly apart, and a propulsive force be generated similar to that which is evolved by the touching of a match to a single grain of powder stored in a magazine. He holds that matter is nothing but forces held in equilibrium, and that if the equilibrium be once destroyed the most tremendous consequences will ensue.
