Telepathy is a logical explanation of many of the ghostly visitations of which the Society for Psychical Research has collected such a mass of data. For example: A dies, let us say in India and B, a near relative or friend, residing in England, sees a vision of A in a dream or in the waking state. A clasps his hands, and seems to utter the words, "I am dying". When the news comes of A's death, the time of the occurrence coincides with the seeing of the vision. The spiritualist's theory is that the ghost of A was an actual entity. One of the difficulties in the way of such an hypothesis is the clothing of the deceased--_can that, too, be disembodied?_ Thought transference (conscious or unconscious), I think, is the only rational explanation of such phantasms. The vision seen by the percipient is not an objective but a subjective thing--a hallucination produced by the unknown force called telepathy. The vision need not coincide exactly with the date of the death of the transmitter but may make its appearance years afterwards, remaining latent in the subjective mind of the percipient. It may, as is frequently the case, be revealed by a medium in a séance. Many thoughtful writers combat the telepathic explanation of phantasms of the dead, claiming that when such are seen long after the death of persons, they afford indubitable evidence of the reality of spirit visitation. The reader is referred to the proceedings of the Society for Psychical Research for a detailed discussion of the _pros_ and _cons_ of this most interesting subject. Many of the so-called materializations of the séance-room may be accounted for by hallucinations superinduced by telepathic suggestions from the mind of the medium or sitters. But, in my opinion, the greater number of these manifestations of spirit power are the result of trickery pure and simple--theatrical beards and wigs, muslin and gossamer robes, etc., being the paraphernalia used to impersonate the shades of the departed, the imaginations of the sitters doing the rest. 2.
