The College of Psychic Studies (founded in 1884 as the London Spiritualist Alliance) is a non-profit organisation based in South Kensington, London. It is dedicated to the study of psychic and spiritualist phenomena. History British National Association of Spiritualists In August 1873, the British National Association of Spiritualists (BNAS) was formed by Thomas Everitt, Edmund Rogers and others at a meeting in Liverpool. Early members included well known spiritualists such as Charles Maurice Davies, Charles Isham, William Stainton Moses, Stanhope Templeman Speer, Morell Theobald and George Wyld. The BNAS carried out experimental séances and investigations into mediumship. It held no dogmatic religious views but was known for "sympathising with the religion of Jesus Christ". The first public meeting of the BNAS took place on 16 April 1874 under the chairmanship of Samuel Carter Hall. By 1875 the BNAS had over 400 members. Its headquarters moved to Great Russell Street, London. In 1879 the German astrophysicist Johann Karl Friedrich Zöllner became an honorary member. William Henry Harrison and his colleagues from the "Scientific Research Committee" of the BNAS were involved in experiments that weighed mediums during materialization séances. Specially built self-recording instruments were used. This was considered controversial and not all members agreed in conducting such experiments. In 1872, Harrison also caused controversy in the spiritualist community by exposing the fraud of spirit photographer Frederick Hudson. In 1875, Harrison with C. F. Varley conducted an unsuccessful experiment in photographing the alleged Odic force of Carl Reichenbach. There was a large dispute between Moses and Harrison over its leadership council. Harrison was expelled from the BNAS. In April 1879, Charles Massey a vice-president resigned, as did Moses on 31 December 1880. In 1882, the BNAS changed name to the Central Association of Spiritualists (CAS). The remaining members such as vice-president Edmund Rogers, one of Moses's loyal supporters tried to reconstruct the society. However, internal conflict between members and financial problems caused the group to dissolve. London Spiritualist Alliance In October 1883 a special conference was set up to discuss the ideas of Moses to form a new society. In March 1884, Moses and others formed the London Spiritualist Alliance (LSA). The first meeting was held on 5 May at the banqueting room in St James's Hall. Moses was president and members included John Stephen Farmer, Massey, Rogers, Stanhope Templeman Speer, Alaric Alfred Watts and Percy Wyndham. After Moses died in 1892, Rogers
