my intention to discuss hypotheses, but rather to put on record the detailed account of a remarkably interesting and thought-provoking experiment. Garrett's claims have since been questioned. The magician John Booth analysed the mediumship of Garrett and the paranormal claims of R101 and considered her to be a fraud. According to Booth Garrett's notes and writings show she followed the building of the R101 and she may have been given aircraft blueprints by a technician from the airdrome. However, the researcher Melvin Harris who studied the case wrote no secret accomplice was needed as the information described in Garrett's séances were "either commonplace, easily absorbed bits and pieces, or plain gobbledegook. The so-called secret information just doesn't exist." Rudi Schneider In the 1920s and early 1930s Price investigated the medium Rudi Schneider in a number of experiments conducted at the National Laboratory of Psychical Research. Schneider claimed he could levitate objects but according to Price a photograph taken on 28 April 1932 showed that Schneider had managed to free his arm to move a handkerchief from the table. After this, many scientists considered Schneider to be exposed as a fraud. Price wrote that the findings of the other experiments should be revised due to the evidence showing how Schneider could free himself from the controls. After Price had exposed Schneider, various scientists, such as Karl Przibram and the magician Henry Evans, wrote to Price telling him that they agreed that Schneider would evade control during his séances and congratulated Price on the success of unmasking the fraud. In opposition, SPR members who were highly critical of Price, supported Schneider's mediumship and promoted a conspiracy theory that Price had hoaxed the photograph. SPR member Anita Gregory claimed Price had deliberately faked the photograph to discredit SPR research and ruin Schneider's reputation. However, a photographic expert testified that the photograph was genuine. SPR member John L. Randall reviewed the Price and Schneider case and came to the conclusion that the photograph was genuine and that Price had caught Schneider in fraud. Helen Duncan In 1931, the National Laboratory of Psychical Research took on its most illustrious case. £50 was paid to the medium Helen Duncan so that she could be examined under scientific conditions. Price was sceptical of Duncan and had her perform a number of test séances. She was suspected of swallowing cheesecloth which was then regurgitated as "ectoplasm". Price had
