It is after all only a few years since the theory of ether waves and vibrations was formulated. Research into psychic phenomena gives us a chain of disconnected phenomena which nevertheless are obviously connected. The distance from telepathy or thought-transference to exteriorized energy or power-transference is but a short one. Science will soon enable us to understand the mechanism of phenomena, and when we once know the true rules or laws governing these phenomena we shall be able to establish spirit communication at will. FOOTNOTES: [12] Sir Arthur Conan Doyle is perhaps to-day an even greater name. But he is not a scientist and is greater as a publicist than as a healer despite his medical degree. But then too--all the Apostles were not of one trade. [13] _Proceedings S.P.R._ [14] _Ibid._, Vol. X, p. 394. [15] This particular ghost has been exorcised without effect. The house has been visited by psychic experts of considerable eminence, including H. Barson and others. The results of all these investigations were uniformly disastrous and disagreeable, and there is reason to believe that in some cases the health and mentality of less experienced investigators were adversely affected. [16] Capt. Hugh Pollard was the author of this theory. His monograph was never printed, but typescripts of his sensational lecture before the members of the now defunct Odic Club were circulated to certain interested parties. He tells me that he had previously spent an interesting night at a haunted house. He was in the company of Mr. Eliott O’Donell and obtained a puzzling and unsatisfactory flashlight photograph of the manifestation that occurred on that occasion. [17] A complete scale of all known ether waves, including the visible spectrum, has been drawn by Professor Lebedeff and is given on page 383 of the English edition of Kolbe’s _Electricity_. [18] This is a little-known fact, but nevertheless a commonplace of physics demonstrable in any lecture room. [19] The actual locality of X---- will be clear to many investigators. [20] The solution used was a solution of radium emanations which gives out α, τ, and γ rays together. It is not well known which ray affects the dissolution of psychoplasm. [21] The mirror of Dr. Dee is still in existence, but the material the mirror is made of is a surface of polished coal. CHAPTER V SEX IN THE NEXT WORLD There is in existence an enormous mass of recorded spirit communication concerning life and death. The one outstanding feature concerning these revelations is that they tell us extremely little. Sometimes the reason given for this withholding of information is that it is forbidden by higher spirits, and it is certainly remarkable that despite the great enthusiasm shown for the principles of democracy in this world, there have never been any revelations of a democratic principle on the higher plane.
