"I have found in my experience that learned scientific men are the most easily duped of any in the world. Instead of having a cold, inert piece of matter to investigate by exact processes and microscopic inspections, they had a clever, bright woman doing her best to mystify them. They could not cope with her. "Professor Richet replied to an article I wrote, upholding his position, and brought Signora Eusapia Paladino to Cambridge, England, where I joined the investigating committee. In the party were Professor Lodge, of Liverpool; Professor F. M. C. Meyer, secretary of the British Society for Psychical Research; Professor Richet and Mr. Henry Sedgwick, president of the society. "I found that the psychic, though giving a great variety of events, confined them to a very limited scope. She was seated during the tests at the end of a rectangular table and when the table was lifted it rose up directly at the other end. It was always so arranged that she was in the dark, even if the rest of the table was in the light; in the so-called light séances it was not light, the lamp being placed in an adjoining room. There were touches, punches and blows given, minor objects moved, some near and some further away; the outline of faces and hands appeared, etc. "When I came to hold her hands I found a key to the mystery. "It was chiefly that she made one hand and one foot do the work of both, by adroit substitution. Given a free hand and a free foot, and nearly all the phenomena can be explained. She has very strong, supple hands, with deft fingers and great coolness and intelligence. "This is the way she substituted one hand for both. She placed one of her hands over A's hand and the other under B's hand. Then, in the movements of the arms during the manifestation, she worked her hands toward each other until they rested one upon the other, with A's hand at the bottom of the pile, B's at the top and both her own, one upon the other, between. To draw out one hand and leave one and yet have the investigators feel that they still had a hand was easy. "With this hand free and in darkness there were great possibilities. There were strings, also, as I believe, which were attached to different objects and moved them. The dim outlines of faces and hands seen were clever representations of the medium's own free hand in various shapes. "It is thought that if a medium was kept clapping her hands she could do nothing with them, but one of the investigators found the Signora slapping her face with one hand, producing just the same sound as if her hands met, while the other hand was free to produce mysterious phenomena. "I have tried the experiment of shifting hands when those who held them knew they were going to be tricked, and yet they did not discover when I made the exchange. I am thoroughly satisfied that Signora Eusapia Paladino is a clever trickster."
