"When Mr. Keely first commenced his wonderful investigations he would have scouted the idea of being in any way whatever associated with so-called spiritualism, but of recent years, and especially during the last few months, he has made such startling progress that he now admits--as I told him a long time ago he would come to admit--that if not in actual experiment, at least in theory he has passed into the world of spirit." The interview being ended, our representative took his departure, after expressing his thanks for the information so willingly given. How far this lady's anticipations of the inventor's success will be realized, or how far her confidence in his integrity is justified, we must leave our readers to judge for themselves. The whole subject is enveloped in much mystery, but it is full of interest, and if half that is narrated of Mr. Keely be true, he is indeed a wonderful man!--The Tatler. CHAPTER IX. 1889-1890. KEELY SUPPORTED BY DISTINGUISHED MEN OF SCIENCE. AERIAL NAVIGATION. Is not ether infinitely more rare and more subtle than air, and exceedingly more elastic and more active? Does it not easily penetrate all bodies? And is it not by its elastic force diffused through the universe?--Sir Isaac Newton. In 1889 a series of short articles were written, which, for the first time, made known to the public that Keely had theories which he was able to sustain by mechanical demonstration: and once more an attempt was made to have men of science acquaint themselves with the theories, and witness the demonstrations. Capitalists also were appealed to, to convince themselves of the existence of an unknown force, and of Mr. Keely's honesty in his efforts to control it for commercial purposes; money being required to enable him to complete his researches for science, and to protect him from those who were harassing him in such a way as to impede his progress at every step. The appeal to capitalists might as well have been made to stone walls; but among the men of scientific and philosophical attainments who were invited, the late Professor Joseph Leidy, M.D., of the Pennsylvania University, and James M. Willcox, Ph.D., author of "Rational Philosophy," and other works, accepted the invitation and attended a series of Keely's researching experiments. For years Mr. Keely's experiments were confined to the production of the force; the raising of a lever; the firing of a cannon; and the showing of a vacuum greater than had ever been produced. Since 1888 he has pursued his researches on a line which enabled him to show uninterrupted progress year after year: so that now he never repeats his experiments; but, discarding or improving his researching instruments, after he has gained the results which his theories lead him to expect, he continues his investigations, thereafter, from the solid basis which he has attained by those researches. The result of the attention given by Professor Leidy and Dr.
