Keely
This professor's (Hertz) researches into the structure of ether are rapidly leading him into the discoveries which constitute what is known as "Keely's secret," and which, when made known, will explain much that is now classed with the inexplicable. Mr. Edison will then better understand the force which he finds so mysteriously associated with electricity: for electricity is but one current of a triune stream, and the dominant current (which has never been controlled by man and never can be, any more than the lightning that flashes in the clouds) carries with it a sympathetically attendant force mysteriously associated, which gives that power of propulsion that induces disturbance of negative equilibrium. [Keelys Discoveries]
"It appears, in my researching experiments, quite evident to me, that under different orders of progressive vibration, when the sixth order is reached on the positive, a condition presents itself in an accompanying agent that adds to the etheric flow a very peculiar action. I call this third agent its sympathetic attendant." [Newton of the Mind]
"Consequently the unition of these sympathetic thirds must take place by gravital assimilation, which is the highest order of sympathetic union. This is the compound etheric flow, or soul of matter. The sympathetic attendant must be the odylic; or, comparatively speaking, its nerve force. Reichenbach exercises a wonderfully far-seeing judgment in his argument on this, the highest preponderable." [Newton of the Mind]
