Here is one of the most marvellous among the new illustrations of the finer forces. But this "ship detector," which acts on the principle of wireless telegraphy, is less potent than are the electric forces in every human being, if it were known how to control and utilize these to serve the purposes of perception. For perception is a faculty that may far transcend both sight and hearing. Perception is a faculty of the soul--often undeveloped; rarely developed to anything like its full possibilities, but capable of locating objects or of discerning persons and events, or of apprehending states of mind in others, regardless of space, as the ship's detector and the shore stations become aware of each other through their relation of finer vibrations. A recent experimenter in electric and super-physical force, M. Tessier d'Helbaicy, states this theory: "Taking as his premise the fundamental law of physical science, that all chemical reaction is accompanied by a generation of heat and electricity, he said to himself that the human body, with the innumerable and incessant chemical reactions presented by all its cells, should create a thermo-electric pile of great power. In any case, the Austrian savant, Reichenbach, in his remarkable series of experiments, has already proved, fifty years ago, that we radiate electric waves of a special kind, visible in the dark under certain conditions, and these present positive and negative poles." This being granted, M. d'Helbaicy has measured the yielding power of the human machine in heat and electricity, and has compared these with what the heat industrial machines can do, such as those run by steam, dynamos, and electric piles.
