The British medium William Roy earned over £50,000 from his séance sitters. He confessed to fraud in 1958 revealing the microphone and trick-apparatus that he had used. The automatic writings of the Irish medium Geraldine Cummins were analyzed by psychical researchers in the 1960s and they revealed that she worked as a cataloguer at the National Library of Ireland and took information from various books that would appear in her automatic writings about ancient history.
In such situations, the clairvoyant medium clearly understands that it is the powerful spirit and not he who is trotting out the facts so fast. It is in fact the spirit, which is providing him with facts, names of the persons and events, dates and other related information. The job of the clairvoyant medium then boils down to just working in tandem with this spiritual energy.
In 1930 the Polish medium Stanisława P. was tested at the Institut Metapsychique in Paris. French psychical researcher Eugéne Osty suspected in the séance that Stanislawa had freed her hand from control. Secret flashlight photographs that were taken revealed that her hand was free and she had moved objects on the séance table. It was claimed by spiritualists that during a series of séances in 1930 the medium Eileen J. Garrett channeled secret information from the spirit of the Lieutenant Herbert Carmichael Irwin who had died in the R101 crash a few days before the séance. Researcher Melvin Harris who studied the case wrote that the information described in Garrett's séances were "either commonplace, easily absorbed bits and pieces, or plain gobblede-gook. The so-called secret information just doesn't exist."
A clairvoyant medium is a psychic who goes into trance, a sleep like state in which he allows his body and senses to be possessed by the spirit which may be his own guiding spirit or that of the seeker. The spirit has an overview of all the happenings on the earth. A clairvoyant medium can speak while lying down. He can also sit down or even walk and make gestures by moving his hands. He can even write or type his messages.
