into thought or mental states similar to those which originally sent them forth. You talk into the receiver of the telephone, and the sound waves are transformed into waves of electricity. These electric waves travel over the wires, and on reaching the other end of the telephone circuit are again transformed into sound-waves which are heard by the ear of the listener. Well, then, when your brain sends out thought waves, these travel until they are received by the apparatus in the brain of another person, when they are re-transformed into thoughts of the same kind that originally caused the thought-waves. I will have much more to say on this subject in the next chapter. I will pause here to point out the difference between the phenomena of this form of telepathy, and the higher form which is really a phase of clairvoyance.
