proven through analysis of a sample of ectoplasm produced by Duncan, that it was made of cheesecloth. Duncan reacted violently at attempts to X-ray her, running from the laboratory and making a scene in the street, where her husband had to restrain her, destroying the controlled nature of the test. Price wrote that Duncan had given her fake ectoplasm to her husband to hide. The ectoplasm of Duncan in another test was analysed by psychical researchers and reported to be made from egg white. According to Price: The sight of half-a-dozen men, each with a pair of scissors waiting for the word, was amusing. It came and we all jumped. One of the doctors got hold of the stuff and secured a piece. The medium screamed and the rest of the "teleplasm" went down her throat. This time it wasn't cheese-cloth. It proved to be paper, soaked in white of egg, and folded into a flattened tube ... Could anything be more infantile than a group of grown-up men wasting time, money, and energy on the antics of a fat female crook. Price wrote up the case in Leaves from a Psychist's Case Book (1933) in a chapter called "The Cheese-Cloth Worshippers". In his report Price published photographs of Duncan in his laboratory that revealed fake ectoplasm made from cheesecloth, rubber gloves and cut-out heads from magazine covers which she pretended to her audience were spirits. Following the report written by Price, Duncan's former maid Mary McGinlay confessed in detail to having aided Duncan in her mediumship tricks, and Duncan's husband admitted the ectoplasm materialisations to be the result of regurgitation. Later Duncan was caught cheating again pretending to be a spirit in the séance room. During Duncan's famous trial in 1944, Price gave his results as evidence for the prosecution. This time Duncan and her travelling companions, Frances Brown, Ernest and Elizabeth Homer were prosecuted and convicted. Duncan was jailed for nine months, Brown for four months and the Homers were bound over. Brocken experiment In 1932, Price travelled to Mount Brocken in Germany with C. E. M. Joad and members of the National Laboratory to conduct a 'black magic' experiment in connection with the centenary of Goethe. The "Bloksberg Tryst", involving the transformation of a goat into a young man by the invocation of a maiden, Ura Bohn (better known as the film actress Gloria Gordon, 1881–1962), produced
