The address of Mrs. Moore, type-copied, was sent to various editors and men of science in Philadelphia, as well as to leading capitalists; and, in this crisis of Keely's connection with the stockholders of The Keely Motor Company, some of these editors rendered substantial aid in making known his critical position; most notably the Inquirer, owned by Mr. Elverson, and the Evening Telegraph, owned by Mr. Warburton, with the result that a decided change in public opinion took place, after these journals announced, in April, that Professor Koenig had tested the energy, employed by Keely, with the most sensitive galvanometer of the university, in the presence of Professor Leidy, Professor Brinton, Doctor Tuttle (a Baltimore physicist) and others, finding no trace of electricity; and by other tests no magnetism. The two professors who thoroughly investigated Keely's theories, and observed his demonstrations, were chosen because they possessed the qualities of mind which Herbert Spencer said constitute the first condition of success in scientific research, viz. "an honest receptivity and a willingness to abandon all preconceived notions, however cherished, if they be found to contradict the truth." Professor Leidy and Dr. Willcox, during their observations of Keely's progressive experimental researches, had expressed no opinion of Keely's theories, other than that they did not correspond with their own ideas; but Professor Koenig boldly said, "I not only think Mr. Keely's theories possible, but I consider them quite probable." Professor Brinton, who made a study of Keely's theories, so mastered them as to be able to suggest to Keely a new line of research, required by Dr. Koenig in the tests proposed; and the synopsis of Keely's philosophy, prepared by Doctor Brinton, has made Keely's hitherto unintelligible language intelligible to men of science. Notwithstanding this favourable result, a New York journalist, under a fictitious name, pretended to have discovered that Keely is a fraud, using well-known forces; which statements were published (with woodcuts of instruments discarded by Keely two years before) in the New York Herald and The Press, in Philadelphia. It is amusing to see how "history repeats itself;" for, in the year 1724, in a letter to the Royal Society, Hatzfeldt attacked Sir Isaac Newton in much the same spirit. One would suppose in reading what Hatzfeldt has written of an invention of his time, that it had been written, word for word, of this ignorant investigator of Keely's experiments in researching. After commenting upon the corruption of human nature as shown, in his day, by want of veracity, and the tendency to vicious misrepresentation, he says: "If the said machine was contrived according to the weak sense and understanding of those who pretend it to be moved in other ways than that declared, it would have been discerned before this.
