researchers in London. An analysis of her ectoplasm revealed it to be made of chewed paper. She was also investigated in 1922 and the result of the tests were negative. In 1925, Price investigated Maria Silbert and caught her using her feet and toes to move objects in the séance room. He also investigated the "direct voice" mediumship of George Valiantine in London. In the séance Valiantine claimed to have contacted the "spirit" of the composer Luigi Arditi , speaking in Italian. Price wrote down every word that was attributed to Arditi and they were found to be word-for-word matches in an Italian phrase-book. Price formed an organisation in 1925 called the National Laboratory of Psychical Research as a rival to the Society for Psychical Research. Price had a number of disputes with the SPR, most notably over the mediumship of Rudi Schneider. Price paid mediums to test them-the SPR criticised Price and disagreed about paying mediums for testing. Price made a formal offer to the University of London to equip and endow a Department of Psychical Research, and to loan the equipment of the National Laboratory and its library. The University of London Board of Studies in Psychology responded positively to this proposal. In 1934, the National Laboratory of Psychical Research, which held Price's collection, was reconstituted as the University of London Council for Psychical Investigation with C. E. M. Joad as chairman and with Price as Honorary Secretary and editor, although it was not an official body of the University. In the meantime, in 1927 Price joined the Ghost Club, of which he remained a member until it (temporarily) closed in 1936. In 1927, Price claimed that he had come into possession of Joanna Southcott's box, and arranged to have it opened in the presence of one reluctant prelate (the Bishop of Grantham, not a diocesan bishop but a suffragan of the Diocese of Lincoln): it was found to contain only a few oddments and unimportant papers, among them a lottery ticket and a horse-pistol. His claims to have had the true box have been disputed by historians and by followers of Southcott. Price exposed Frederick Tansley Munnings, who claimed to produce the independent "spirit" voices of Julius Caesar, Dan Leno, Hawley Harvey Crippen and King Henry VIII. Price invented and used a piece of apparatus known as a voice control recorder and proved that all the voices
