Spiritualists distinguish between physical phenomena and psychic phenomena. The use of this distinction is obvious. When a man reads some such history of the movement as Podmore's, and then the works of Truesdell, Robinson, Maskelyne, Carrington, and others who have time after time exposed the ways of mediums, he is very ill-disposed to listen to stories of materialization, levitation, spirit photographs, spirit messages, spirit music, spirit voices, or anything of the kind. He knows that each single trick has been exposed over and over again. So the liberal Spiritualist urges him to leave out "physical" phenomena and concentrate on the "psychic." It is a word with an aroma of refinement, spirituality, even intellect. It indicates the sort of thing that respectable spirits _ought_ to do. So we will turn to the psychic phenomenon of clairvoyance. Here at once the reader's resolution to approach the subject gravely is disturbed by the recollection of a recent event. Many a reader would, quite apart from the question of consolation, like to find something true in Spiritualism. He may feel, as Professor William James did, that the mass of fraud is so appalling that, for the credit of humanity, we should like to think that it is the citizens of another world, not of ours, who are responsible. He may feel that, if it is all fraud, a number of quite distinguished people occupy a very painful position in modern times. He would like to find at least something serious; something that is reasonably capable of a Spiritualist interpretation. But as soon as he approaches any class of phenomena some startling instance of fraud rises in his memory and tries to prejudice him. In this case it is the "Masked Medium." A recent case in the law courts has brought this to mind. In 1919, when the _Sunday Express_ was making its grave search for ghosts, in order to rebuke the materialism of our age, it offered £500 for a materialization. A gentleman, who (with an eye on the police) genially waived the money offer aside, offered to bring an unknown lady and present a materialization, and some startling feats of clairvoyance in addition. A sitting was arranged, and the lady, who wore a mask, gave a clairvoyant demonstration that could not be surpassed in all the annals of Spiritualism. Her ghost was rather a failure; though Lady Glenconnor, who has the true Spiritualist temperament, recognized in it an "initial stage of materialization." But the clairvoyance was great. The sitters, while the lady was still out of the room, put various objects connected with the dead (a ring, a stud, a sealed letter, etc.) in a bag. The bag was closed, and was put inside a box; and the lady, who was then introduced, described every object with marvellous accuracy. Sir A. C. Doyle said that the medium gave "a clear proof of clairvoyance." Mr. Gow said that he saw "no normal explanation."
