London Spiritualist Alliance

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.

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 April 16th, 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.
