TELEPATHY, the power of communi cation between one mind and another by means unknown to the ordinary sense organs, and usually called thought trans ference. Members of the Society for Psychical Research believe that they have established the fact that such power exists in the material universe and have attempted to turn the assumption to account in the explanation of certain unexplained natural phenomena. Tele pathy is not clairvoyance, for it has been demonstrated by many experiments care fully made by competent persons that sensations, ideas, information and men tal pictures can be transferred from one mind to the other without the aid of speech, sight, hearing, touch or any of the ordinary methods by communicating such impressions or information. Some persons can voluntarily project the mind or some independent mental activity a distance of 100 or 1,000 miles so that it can make itself known and recognized, perform acts and even carry on a con versation with the person to whom it is sent.
Scientific work on thought transfer ence began systematically in England in 1882, when the Society for Psychical Re search was founded under the presidency of Professor Sidgwick of Cambridge.
Professor Crookes has outlined a theory according to which thought transference is effected by inconceivably minute and rapid ether waves. After pointing out that vibrations of ether of a certain rapidity produce light, he says that there are higher rates of vibrations which are utterly imperceptible to our senses and it is not inconceivable that intense thought, concentrated toward a sensitive being with whom the thinker is in close sympathy, may induce a telepathic chain along which brain waves can go straight to their goal without loss of energy due to distance.
