Note E — Chapter V · Thought-Transference and Telepathy.

Thought (says Professor Houston) is accompanied by molecular vibrations in the grey matter of the brain, and these brain molecules, like everything else, are immersed in and interpenetrated by ether; this being so, their vibrations must set up wave-motions in the ether, and these must spread out from the brain in all directions. Further, these brain-waves, or thought waves, being thus sent out into space, will produce some phenomena, and, reasoning by analogy we may expect that—as in the case of sound-waves—sympathetic vibrations will be set up in bodies similar to that which generates the waves, if those bodies are attuned to respond. Again, reasoning by analogy, we may expect—as in electric resonance—that such oscillations would be set up as are found when electric waves are sent out and, meeting a circuit in consonance with them, set up in that circuit oscillations like their own.

In view of these facts, which are well ascertained, he (Professor Houston) considers that it does not seem improbable that a brain engaged in intense thought should act as a centre for thought-radiation, nor that these radiations, proceeding outwards in all directions, should affect other brains on which they fall, provided that these other brains are tuned to vibrate in unison with them.

Light waves are etheric vibrations, and it would seem that these brain-waves should “partake of the nature of light.” If so, why should it not be possible to obtain, say, by means of a lens, a photographic impression of them?

Such a thought-record suitably employed might be able to awaken at any subsequent time in the brain of a person submitting himself to its influence thoughts identical to those recorded.—English Mechanic.
