The Problems of Psychical Research / Experiments and Theories in the Realm of the Supernormal

The author reviews psychical phenomena and the methods used to investigate them, arguing that establishing reliable evidence is a prerequisite to scientific progress. The text surveys laboratory instruments and experimental approaches, proposes physiological and psychological hypotheses about consciousness and the will, and presents work in psychic photography and related trials. Other chapters examine hallucination, telepathy, spiritistic mediumship, the Ouija board, mind cure, witchcraft, and how traditional tales preserve psychological observations. The tone combines constructive theorizing with practical suggestions for more rigorous future inquiry.
