became the president. The LSA obtained a wider membership under the leadership of Rogers including notable figures such as Alfred Russel Wallace. In 1886, Eleanor Sidgwick from the Society for Psychical Research (SPR) claimed that the medium William Eglinton was fraudulent. Members from the LSA and articles in the journal Light supported Eglinton and accused Sidgwick of bias and prejudice. Some spiritualist members resigned from the SPR. In 1925, Arthur Conan Doyle became president and the LSA bought a new headquarters at Queensberry Place, South Kensington. Between October 1930 and June 1931 the materialization medium Helen Duncan was investigated by the LSA. Despite early favourable reports, an examination of Duncan's ectoplasm revealed it was made of cheesecloth, paper mixed with the white of egg and lavatory paper stuck together. One of Duncan's tricks was to swallow and regurgitate some of her ectoplasm and she was persuaded to swallow a tablet of methylene blue before one of her séances to rule out any chance of this trick being performed and because of this no ectoplasm appeared. The journal Light endorsed the court decision that Duncan was fraudulent and supported Harry Price's investigation that revealed her ectoplasm was cheesecloth. College of Psychic Studies In 1955 the LSA changed its name to the College of Psychic Science. In 1970 it became the College of Psychic Studies. According to psychical researcher Simeon Edmunds, by the 1955 name change there was "no doubt that from that time onwards the society was no longer a spiritualist one" as it was accepting non-spiritualist members and held no corporate opinion on the question of survival. In the 1960s, after a revival in spiritualism, the college associated itself with the Society for Psychical Research, collecting thousands of case files. Paul Beard was the president of the college for 16 years. In 2006, the college offered twelve courses on psychic abilities. In April 2021 The College re-launched their website with an expanded programme of online courses, talks and events able to be completed online. Their current president, Geoffrey Dart C.B.E, references this being partly in response to the challenges of running in-person events during the Covid-19 pandemic. Publications Books In 1930, the London Spiritualist Alliance published a series of five books under L.S.A Publications Ltd. These were: Helen A. Dallas. Human Survival and its Implications. Charles Drayton Thomas. The Mental Phenomena of Spiritualism. Stanley De Brath. The Physical Phenomena of
