What is Heat? Heat may be classed as a vibro-atomic element, not exceeding 14,000 vibrations per second at its greatest intensity, latent in all conditions of matter both visible and invisible. The velocity of the sympathetic flows which emanate from our solar world, the sun, coming into contact with our atmospheric medium, liberates this element in all the different degrees of intensity that give warmth to our earth. Light is another resultant; the different intensities of which are produced according to the different angles of this sympathetic projectment. The light that emanates from a glow-worm is the resultant of the action of the sympathetic medium of the insect itself on a centre of phosphorescent matter, which is included in its structure. The resultant of the two conditions are quite different, but they are governed by the same laws of sympathetic percussion. Radiation is the term used to express the reaching out of the thermal element, after its liberation from its corpuscular imprisonment, to be re-absorbed or returned again to its sympathetic environment; teaching us a lesson in the equation of disturbance of sympathetic equilibrium. Force. "By what means is force exerted, and what definitely is force? Given that force can be exerted by an act of will, do we understand the mechanism by which this is done? And if there is a gap in our knowledge between the conscious idea of a motion and the liberation of muscular energy needed to accomplish it, how do we know that a body may not be moved without ordinary material contact by an act of will?" These questions were asked by Professor Lodge in his paper on "Time;" and as Keely contends that all metallic substances after having been subjected to a certain order of vibration may be so moved, let us see how he would answer these questions. When Faraday endeavoured to elaborate some of his "unscientific notions in regard to force and matter," men of science then said that Faraday's writings were not translatable into scientific language. The same has been said of Keely's writings. Pierson says, "The very fact that there is about the product of another's genius what you and I cannot understand is a proof of genius, i.e., of a superior order of faculties." Keely, who claims to have discovered the existence of hidden energy in all aggregations of matter, imprisoned there by the infinite velocity of molecular rotation, asserts that "physicists in their mental rambles in the realm of analytical chemistry, analytical as understood by them, have failed to discover the key-note which is associated with the flow of the mental element;" that "they have antagonized or subverted all the conditions," in this unexplored territory of negative research, which he has demonstrated as existing in reference to latent energy locked in corpuscular space. These antagonisms might have been sooner removed had those physicists who witnessed some of Keely's experiments, while he
