These things being so--both these causes being apparently operative along the whole series of "scryers," or crystal-gazers, from the most unstable to the most scientific--one might be tempted to assume that these two clues, if we could follow them far enough, would explain the whole group of phenomena. Persons who have not _seen_ the phenomena, indeed, can hardly be persuaded to the contrary. But the real fact is, as even those who have seen much less of crystal-gazing than I have will very well know, that these explanations cannot be stretched to cover a quarter--perhaps not even a tenth--of the phenomena which actually occur. Judging both from the testimony of scryers themselves, and from the observations of Dr. Hodgson and others (myself included), who have had many opportunities of watching them, it is very seldom that the gaze into the glass ball induces any hypnotic symptoms whatever. It does not induce such symptoms with successful scryers any more than with unsuccessful. Furthermore, there is no proof that the gift of crystal-vision goes along with hypnotic sensibility. The most that one can say is that the gift often goes along with _telepathic_ sensibility; but although telepathic sensibility may sometimes be quickened by hypnotism, we have no proof that those two forms of sensitiveness habitually go together. The ordinary attitude of the scryer, I repeat, is one of complete detachment; an interested and often puzzled scrutiny and analysis of the figures which display themselves in swift or slow succession in the crystal ball.
