The spiritualists Arthur Conan Doyle and W. T. Stead were duped into believing Julius and Agnes Zancig had genuine psychic powers. Both Doyle and Stead wrote that the Zancigs performed telepathy. In 1924 Julius and Agnes Zancig confessed that their mind reading act was a trick and published the secret code and all the details of the trick method they had used under the title of Our Secrets!! in a London Newspaper.[144]
In the later half of the 20th century, Western mediumship developed in two different ways. One type involved clairaudience or sensitives who hear spirit, and then relay what they hear to their clients.[29] The other incarnation of non-physical mediumship is a form of channeling in which the channeler goes into a trance, or "leaves their body", allowing a spirit entity to borrow their body, who then speaks through them.[30] When in a trance the medium appears to come under the control of the spirit of a departed soul, sometimes entering into a cataleptic state,[31] although modern channelers may not.[citation needed] Some channelers open the eyes when channeling, and remain able to walk and behave normally. The rhythm and the intonation of the voice may also change completely.
"Mental mediumship" is communication of spirits with a medium by telepathy. The medium mentally "hears" (clairaudience), "sees" (clairvoyance), and/or feels (clairsentience) messages from spirits. Directly or with the help of a spirit guide, the medium passes the information on to the message's recipient(s). When a medium is doing a "reading" for a particular person, that person is known as the "sitter".
In 1925, Samuel Soal claimed to have taken part in a series of séances with the medium Blanche Cooper who contacted the spirit of a soldier Gordon Davis and revealed the house that he had lived in. Researchers later discovered fraud as the séances had taken place in 1922, not 1925. The magician and paranormal investigator Bob Couttie revealed that Davis was alive, Soal lived close to him and had altered the records of the sittings after checking out the house. Soal's co-workers knew that he had fiddled the results but were kept quiet with threats of libel suits.[145]
In March 1902 in Berlin, police officers interrupted a séance of the German apport medium Frau Anna Rothe. Her hands were grabbed and she was wrestled to the ground. A female police assistant physically examined Rothe and discovered 157 flowers as well as oranges and lemons hidden in her petticoat. She was arrested and charged with fraud.[105] Another apport medium Hilda Lewis known as the "flower medium" confessed to fraud.[106]
In the late 1920s and early 1930s there were around one quarter of a million practising Spiritualists and some two thousand Spiritualist societies in the UK in addition to flourishing microcultures of platform mediumship and 'home circles'.[18] Spiritualism continues to be practised, primarily through various denominational Spiritualist churches in the United States, Canada, Australia and the United Kingdom. In the United Kingdom, over 340 Spiritualist churches and centres open their doors to the public and free demonstrations of mediumship are regularly performed.[19]
