John W. Edmonds (1799-1874), a prominent New York judge, and George T. Dexter, a New York physician, met though their shared interest in the spirit world. They were both dabbling in the spiritualist movement - first with scepticism - and decided to join forces in their investigations of such phenomena as 'spirit-rappings'. Dexter eventually found himself 'fully developed as a writing medium', with his pen controlled by unseen forces. Their conclusions, published in 1853 in Spiritualism, which went into numerous editions and was followed in 1855 by a second volume, caused much controversy. Drawing from their observations, the work gives examples of the authors' purported interaction with the spirit world and their journey from doubt to belief. Volume 2 sees Dexter develop as a 'speaking medium' and includes transcriptions taken by Edmonds of what the spirits relayed through his co-author during the meetings of their circle of spiritualists.
