The author is director of the American Psychical Institute, so that alone should carry weight with the fast growing market for books in this field. Here, between covers, is a general survey of virtually all phases of psychic phenomena, presumably based on concrete evidence and fact. The opening chapters reveal a thoroughly scholarly approach; he knows the field from Bergson and James down. Then he goes into manifestations, with specific instances of each type -- levitation, telepathy, clairvoyance, ghosts, yoga, fire walking, dervishes, etc. He does not attempt to present scientific explanations -- ""seeing is believing."" Evidence drawn from Oriental and African sources.
