Telepathy and the Subliminal Self [PDF ebook] 
An Account of Recent Investigations Regarding Hypnotism, Automatism, Dreams, Phantasms, and Related Phenomena

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. In the following papers intelligent readers, both in and out of the medical profession, will find these subjects fairly stated and discussed, and to some of the questions asked, fair and reasonable answers given. It is with the hope of aiding somewhat in the efforts now being made to rescue from an uncertain and unreasoning supernatural ism some of the most valuable facts in nature, and some of the most interesting and beautiful psychical phenomena in human experience, that this book is offered to the public.
