Sir Williams Crooks president of Royal Society in Bristol considered telepathy as a fundamental law of thought and images transference.
If telepathy exist we have two physical facts; the physical charge in the brain A thebsugestor and the analogous physical charge in the brain B the recipient if the suggestion. Between these two events there must exist a train of physical causes.
Such a sequence can occur only through a intervening medium.
All phenomena in the universe are presumably in some way continuous. Ether Vibrations have powers and attibutes abundantly equal to any demand even the transmission of thought.
The essential cells if nerves do not actually touch but are separated by a narrow gap which widens in sleep while it narrows almost to extinction during mental activity.
This condition is so singularity like that of Branly or Lidge ciherer a device that led Marconi to the discovery of wireless telegraphy.
Our physical force creates a movement of Ether which transmits itself afar like all movements of Ether and becomes perceptible to brains in harmony with our own.
The transformation of a psychic action into etheral movement and the reverse may be analogies to what take place on a telephone where the receptive plate which is identical to the plate at the other end reconstruct the the sonorous movement transmitted not by means of sound but by electricity.
There are undoubtedly Vibrations set up in the brain when one thinks and there are waves of thought just as there are waves of electricity.
There is an increase of temperature in the human brain during periods of thoughts activity and there are constant chemical changes in the structure going on when the brain cells are active.
This is akin to generation of electricitry in a battery and acts in the same way producing vibrations and transmitting them to the brain of another.
Mind travels in waves from one brain to another just as electricity from the transmitter to receiver.
By holding this picture in your mindyounwill have the whole practical theory in condensed form right before you so that you might be able to act accordingly.
