7th. Keely has constructed instruments by which he is endeavouring to determine the nature of the triune action of the polar terrestrial stream, or envelope, as regards its vibratory philosophy. He is seeking to demonstrate its sympathetic association with the celestial stream, or luminiferous track,--the compound etheric field, from which all planetary masses spring. He considers the electric stream to be one of the triune sympathetic streams which help to build up, in their order of triple concentration, the high vitality of the polar stream, or, more correctly, the magnetic-electric terrestrial envelope, without which all living organisms would cease to exist. He classes the cohesive force of molecular masses as the dominant order of the electric stream, the molecule owing its negative attractive quality to the magnetic element. In Keely's beautiful experiments in antagonizing the polar stream, recently given before men of science, he has copied in his instruments the conditions which Nature has established in all her terrestrial ranges,--conditions necessary in order to equate a state of sympathetic disturbance for the revitalization of what is continually being displaced by negative dispersion. These mechanical conditions are principally differential vibratory settings on molecular aggregations of the metallic masses of gold, silver, and platinum. 8th. He has discovered that the range of molecular motion in all quiescent masses is equal to one-third of their diameters, and that all extended range is induced by sound-force, set at chords of the thirds which are antagonistic to the combined chords of the mass of the neutral centres that they represent, no two masses being alike, and that at a certain increased range of molecular motion, induced by the proper acoustic force, the molecules become repellent, and that when the sympathetic centres are influenced by a vibration concordant to the one that exists in themselves, the molecules become attractive; that the repellent condition seems to take place at a distance of about ten of the diameters of the molecules, this distance representing the neutral line of their attractive force, or the dividing line between the attractive and the repellent. Beyond this line, perfect triple separation takes place; inside of it, perfect attractive association is the result.
