Facsimile edition with notes, bibliography, glossary and index. No mere knowledge of magical secrets will ever guarantee the reader from being deceived by fraudulent mediums. Actual acquaintance with practical methods and long experience of the conduct of seances is necessary before he will be able to distinguish the genuine from the fraudulent, and when he finds himself able to discern faintly the line which divides the two he will be in a position to understand more fully the enormous difficulties which confront the investigators of psychical phenomena. It is hoped that the reappearance of this mediumistic classic will whet the reader's appetite and make him eager for still further information.
