In such fields of research, Mr. Keely finds little leisure. Those who accuse him of "dilly-dallying," of idleness, of "always going to do and never doing," of "visionary plans," etc., etc., know nothing of the infinite patience, the persistent energy, which for a quarter of a century has upheld him in his struggle to attain this end. Still less, if possible, is he understood by those who think he is seeking self-aggrandizement, fame, fortune, or glory. The time is approaching when all who have sought to defame this discoverer and inventor, all who have stabbed him with unmerited accusations, all who have denounced him as "a bogus inventor," "a fraud," "an impostor," "a charlatan," "a modern Cagliostro," will be forced to acknowledge that he has done a giant's work for true science, even though he should not live to attain commercial success. But history will not forget that, in the nineteenth century, the story of Prometheus has been repeated, and that the greatest mind of the age, seeking to scale the heavens to bring down the light of truth for mankind, met with Prometheus's reward. Note.--Dr. Hartmann, in a report, or condensed statement, in reference to Keely's discovery, writes as follows: "He will never invent a machine by which the equilibrium of the living forces in a disordered brain can be restored." As such a statement would lead the reader of the report to fancy that Keely expected to invent such an instrument, it is better to correct the error that Dr. Hartmann has fallen into. Keely has never dreamed of inventing such an instrument. He hopes, however, to perfect one that he is now at work upon, which will enable the operator to localize the seat of disturbance in the brain in mental disorders. If he succeeds, this will greatly simplify the work of "re-adjusting opposing conditions"; and will also enable the physician to decide whether the "differential disaster" has taken place which prevents the possibility of establishing the equation that is necessary to a cure. According to Keely's theories it is that form of energy known as magnetism--not electricity--which is to be the curative agent of the future, thus reviving a mode of treatment handed down from the time of the earliest records, and made known to the Royal Society of London more than fifty years since by Professor Keil, of Jena, who demonstrated the susceptibility of the nervous system to the influence of the natural magnet, and its efficacy in the cure of certain infirmities. As Cheston Morris, M.D., has well said in his paper on "Vital Molecular Vibrations," "We are entering upon a new field in biology, pathology, and of course, therapeutics, whose limits are at present far beyond our ken."
