The subtle _rôle_ which telepathy plays in so-called spirit manifestations must now be apparent. It is not only in the class of phenomena to which we have alluded that its power is manifest, but it reappears in all classes and phases of phenomena popularly attributed to spirits. The greater part of the mystery which surrounds these manifestations, aside from the purely physical phenomena, is directly traceable to telepathy; and it explains that which, without its aid, would be inexplicable on any other hypothesis than that the manifestations proceed from disembodied spirits. In concluding the discussion of this branch of the subject, I desire distinctly to impress upon the mind of the reader an important proposition which seems to have been lost sight of by many who are otherwise inclined to give full credit to telepathy as a means of explaining many so-called spirit phenomena. It is this:-- _It is not necessary that any member of a circle should be in possession of objective knowledge of a fact in order to be able to communicate it telepathically to the medium._ The reason will be obvious, after a moment's reflection, to any one who admits the existence of the power of telepathy. If the power is possessed by A to communicate a telepathic message to B, it follows that B can communicate the same message to C, and C can convey it to D, and so on, _ad infinitum_. This proposition will not be gainsaid by any one who admits that A can convey a telepathic message to B. D may have no objective knowledge of A or of B, but is _en rapport_ with C. Now, we will suppose that a disaster happens to A. He is missing; he is drowned; but no one possesses any objective knowledge of the fact, and his friends institute a vain search, no one having the remotest idea of what has happened to him. B, his mother, receives a telepathic message, conveyed by A at the moment of his death to her subjective mind, informing her of the sad accident. But not being sensitive to subjective impressions, it is impossible for her subjective mind to convey the message above the threshold of her consciousness. She is, therefore, objectively ignorant of the fact, although her subjective mind is fully cognizant of all its sad details. In the mean time, C, a sympathetic neighbor, _en rapport_ with B, subjectively perceives that which is so strongly impressed upon the subjective mind of the mother. C is also unable to elevate the knowledge above the threshold of her consciousness; but she is a believer in spiritism, and volunteers to visit a neighboring city and consult a medium. She does so; and the moment she becomes _en rapport_ with the medium, the telepathic message is delivered, and the medium perceives, objectively as well as subjectively, the details of the disaster which befell A. He describes the whole transaction, and locates the exact spot where the body may be found. Subsequent investigation demonstrates the exact knowledge
