[DOYLE, Arthur Conan (1859-1930), introduction]. -- MOSELEY, Sydney A. An Amazing S?ance and an Exposure. London and Edinburgh: Sampson Low, Marston & Co., 1919.8vo. 4 photographic plates. Original tan cloth lettered in black (textblock slightly bulging); ORIGINAL DUST JACKET (extremities soiled, some light chipping at head, small stain on rear flap).FIRST EDITION. ?Mr. Sydney Moseley is the latest example of a gentleman who has approached the subject of spirit survival and spirit communion with an open mind, and has been convinced by the evidence. His researches have not extended over a long period of time, but he has had exceptional opportunities of seeing and recording some outstanding cases which must make a deep impression upon any mind capable of reason. He has asked me to write an introduction to his little book, which I do the more willingly because I have myself had some experience of three of the leading examples of mediumship to which he refers?
