Mr. Keely is his own worst enemy. When suspected of fraud he acts as if he were a fraud; and in breaking up his vibratory microscope and other instruments which he had been years in perfecting, at the time he was committed to prison in 1888, he laid himself open to the suspicion that his instruments are but devices with which he cunningly deceives his patrons. Yet these same instruments he has, since their reconstruction, dissected and explained to those who approached him in the proper spirit. It is only when he has been subjected to insulting suspicions by arrogant scientists that he refuses to explain his theories, and to demonstrate their truth, as far as it is in his power to do so. "Keely may be on the right track, after all," remarked an English scientist, after Prof. Hertz had made known his researches on the structure of ether; "for if we have imprisoned the ether without knowing it, why may not Keely know what he has got a hold of?" Norman Lockyer, in his "Chemistry of the Sun," confirms Keely's theories when he writes, "The law which connects radiation with absorption and at once enables us to read the riddle set by the sun and stars is, then, simply the law of 'sympathetic vibration.'" "It is remarkable," says Horace W. Smith, "that in countries far distant from each other, different men have fallen into the same tracks of science, and have made similar and correspondent discoveries, at the same period of time, without the least communication with each other." So has it been in all periods of progress and in all branches of science, from the discoveries of Euclid and Archimedes down to those of Galileo and Descartes and Bacon, and, in later days, of Gilbert and Newton and Leibnitz, then Franklin and Collison and Von Kliest and Muschenbröck; and now Keely and Hertz and Depuy and Rücker and Lockyer are examples. Never has a discovery leading to a new system been begun and perfected by the same individual so far as Keely is doing; but, as Morley has said, "the representative of a larger age must excel in genius all predecessors." The application of his discovery to the service of humanity is the aim and end of Keely's efforts; his success means "vastly more than the most sanguine to-day venture to predict," promising "a true millennial introduction into the unseen universe, and the glorious life that every man, Christian or sceptic, optimist or pessimist, would gladly hope for and believe possible." (Thurston.) Not the least among the ultimate blessings to our race which Keely's discovery foreshadows is the deeper insight that it will bestow into the healing power of the finer forces of nature, embracing cures of brain and nerve disorders that are now classed with incurable diseases.
