This is an organized event that can take place in an auditorium, church or even a TV studio. Participants are picked out from the audience randomly, and the spiritualist or medium passes messages, either directly from the spiritual realm or via his or her personal spirit guide. It’s a good way to see how it all works, but you are playing a numbers game as the chances of you receiving a message are remote.
In September 1878 the British medium Charles Williams and his fellow-medium at the time, A. Rita, were detected in trickery at Amsterdam. During the séance a materialized spirit was seized and found to be Rita and a bottle of phosphorus oil, muslin and a false beard were found amongst the two mediums. In 1882 C. E. Wood was exposed in a séance in Peterborough. Her Indian spirit control "Pocka" was found to be the medium on her knees, covered in muslin.
