A good deal of water has flowed under the bridges since the world laughed at the “table-turnings” of the Count de Gasparin in Paris in 1854, or thought that Spiritualism was down and out for good with the exposure of Eusapia Paladino. Sir Arthur Conan Doyle is no doubt justified when he claims that vastly more evidence has been collected for the genuineness of certain spiritual phenomena than is required to prove very many other scientific matters which cannot be tested by the majority of us. An investigation like that conducted by Dr. W. J. Crawford with the medium Miss Kathleen Goligher, carried on during three years in Belfast under the most exact and rigid conditions excluding the least possibility of fraud, has demonstrated scientifically the existence of a psychic material in the human body which can be weighed, felt, and photographed, and which takes as real a place in the outfit of the human machine as that of the hand with which I write this article. The census conducted by Mr. Gurney, or that by Prof. Henry and Mrs. Sidgwick, with the fifty odd weighty volumes of evidence collected by the Society for Psychical Research, completely lifts apparitions of the dead out of the world of chance and mere imagination. Lastly, the investigation of such cases as those well set out by Sir William Barrett in his book, On the Threshold of the Unseen, and the work that has been done by such men as Bennett, Crooks, Maxwell, Flammarion, Hyslop, Lodge, Wallace, and scores more, together with those we have already mentioned, simply compels belief in the existence and operation of dis-carnate spiritual powers. Catholics have Mr. J. G. Raupert to confirm them.
