In 1878 Mr. Keely conceived and constructed an instrument which he called a "vibratory lift," and, while experimenting on the improvised multiplication by this medium, he had occasion to put a piece of marble, weighing twenty-six pounds, on a steel bar to hold it in place, when then and there his first discovery of the disintegration of mineral substance took place. From that time progressive research of the most arduous nature has brought him to his present standard in vibratory physics. In the winter of 1881-82, when threatened with imprisonment by the managers of the Keely Motor Company for not disclosing his secret to them, which then would have been like pricking a bubble, he destroyed his vibratory lift and other instruments that he had been years in perfecting. At this time so hopeless was Keely, that his plans were made to destroy himself, after destroying his devices. At this critical juncture he received unexpected aid. Again, in 1888, before he was taken to a felon's cell in Moyamensing Prison by decree of Judge Finletter for alleged contempt of court, he broke up his vibratory microscope, his sympathetic transmitter, and some devices, which have taken much of his time since to reconstruct. It would seem to be incomprehensible that a man who believes he has been specially endowed by Providence to convey great truths to the world, should have destroyed instruments which were the result of the labour of many years of research; but Schopenhauer tells us that genius possesses an abnormally developed nervous and cerebral system that brings with it hyper-sensibility, which in union with intensity of will-energy, that is also characteristic of genius, occasions quick changes of mood and extravagant outbursts. Schopenhauer also explains why it is that men of genius are ignored by the age in which they appear:--"The genius comes into his age like a comet into the paths of the planets, to whose well-regulated and comprehensible order its entirely eccentric course is foreign. Accordingly he cannot go hand in hand with the existing regular progress to the culture of the age, but flings his works far out on the way in front (as the dying Emperor flung his spear among the enemy), which time has first to overtake. The achievement of the man of genius transcends not only the power of achievement of others, but also their power of apprehension; therefore they do not become directly conscious of him. The man of talent is like the marksman who hits a mark the others cannot hit; the man of genius is like the marksman who hits a mark that the sight of others cannot even reach." In one sense this truth applies to all men, for, says Cicero, no man is understood excepting by his equals or his superiors.
