Answer.--"From twelve drops of water a force can be developed that will fill a chamber of seven pint volume no less than six times with a pressure of ten tons to the square inch." III. "In other words, if you put so many pounds of energy into vibratory motion, how many foot-pounds do you get out of this?" Answer.--"All molecular masses of metal represent in their interstitial molecular spaces incalculable amounts of latent force, which, if awakened and brought into intense vibratory action by the medium of sympathetic liberation, would result in thousands of billions more power in foot-pounds than that necessary to awaken it. The resultant development of any and all forces is only accomplished by conditions that awaken the latent energy they have carried with them during molecular aggregation. If the latent force that exists in a pound of water could be sympathetically evolved or liberated up to the seventh subdivision or compound inter-etheric, and could be stored free of rotation, it would be in my estimation sufficient to run the power of the world for a century." This statement gives another of Keely's discoveries to the world, viz., that molecular dissociation does not create energy, as men have asserted Keely has claimed, but supplies it in unlimited quantities, as the product of the latent energy accumulated in molecular aggregation. This is to the physicist as if Keely had asserted that two and two make a billion, but as a man of science, who is held to be "the scientific equal of any man in the world," has come forward to make known that, in his opinion, "Keely has fairly demonstrated the discovery of a force previously unknown to science," the discoverer at lasts feels at liberty to make public the nature of his discoveries. Until Dr. Joseph Leidy had taken this stand, Mr. Keely could not, without jeopardizing his interests, and the interests of the Keely Motor Company, have made known in what particulars his system conflicts with the systems upheld by the age in which we live.
