Professor Fitzgerald's lecture on electro-magnetic radiation shows that scientific men are beginning to realize, and that fairly, the truths appertaining to the new philosophy. The professor admits that electricity and magnetism are of differential character, and he is right. The progressive subdivision, induced on molecules by different orders of sympathetic vibration, and the resultant conditions evolved on the inter-molecule and inter-atom, by introductory etheric dispersion, prove that the magnetic flow of itself is a triple one, as is also the electric. Again, the professor says that electricity and magnetism would be essentially interchangeable if such a thing existed as magnetic conduction, adding: 'It is in this difference that we must look for the difference between electricity and magnetism.' Thus you see how plain it is that progressive scientists are approaching true science. The rotation of the magnetic needle, as produced in my researching experiments, proves conclusively that the interchange spoken of, in Professor Fitzgerald's lecture, is a differentiated vibratory one, in which the dominant and enharmonic forces exchange compliments with each other, in a differential way; thus inducing rotation, in other words polarization and depolarization. The transmission of sympathetic atomic vibration, through a triple nodal transmitter, induces an inter-atomic percussion, that results in triple atomic subdivision, not oscillating across the diameter of the atom, but accelerating to an infinite degree the atomic film that surrounds it and at the same time extending the vibratory range of the atom far enough to set free the gaseous atomic element. Molecular Dissociation. If our sight could reach into the remote depths of the interstitial spaces which exist between the molecular ranges, and observe their wonderful action, in their oscillating motion, to and from each other, as guided by the Infinite in their sphere of vibrating action--could we comprehend the astonishing velocity of their gaseous capsules, combined as it is with the accompanying acoustic force, we would be, as it were, paralyzed with amazement. But we would then only be bordering on the still more remote depths of the interstitial atomic realm, stretching far down towards the neutral depths of the inter-atomic; and again, still farther to the borders of its etheric neutral radiating centre.
