H. Myers (1843-1901) and Frank Podmore (1856-1910), all leading members of the Society for Psychical Research, was first published in 1886. It documents over 700 case studies of ghost-seeing, and aimed to revolutionise thinking about ghosts by proposing a theory that explained ghost-seeing through the idea of telepathy. Volume 1 includes an introduction by Myers and an explanation of the analytical methods used in the study. It then focuses on hypnotism, the telepathic transference of ideas, mental pictures and emotional impressions, dreams, and hallucinations, and contains an impressive essay on the history of witchcraft. This pioneering study is an indispensable source for the history of psychical research. It provides detailed insights into the Victorian fascination with the occult and the supernatural, and is still the most extensive collection of ghost-seeing accounts available.
