Home's usual phenomena were messages, the moving of objects (presumably at a distance), and the playing of an accordion which he held with one hand under the shadow of the table. But from an early date in America he had been accustomed occasionally to "materialise" hands (as it was afterwards called). The sitters would, in the darkness, faintly see a ghostly hand and arm, or they might feel the touch of an icy limb. Mr. Merrifield and the other sitters saw a "spirit-hand" stretch across the faintly lit space of the window. But Mr. Merrifield says that Home sat, or crouched, low in a low chair, and that the "spirit-hand" was a false limb on the end of Home's arm. At other times, he says, he saw that Home was using his foot."
I was 13 when my mom dragged my brother and me to a "psychic." We were visiting family in Malaysia and somewhere amongst a few palm oil plantations was the house of an old woman who claimed to be able to channel Buddha. My mother was enthralled during the hour-long ordeal, during which the woman basically rolled her eyes often so the whites were showing, dropped her voice a few octaves, and made astonishingly mundane statements that could've applied to anyone (examples: our house had ants out front; my grandma was old and having some health problems). Combined with my love of Harry Houdini (who spent the last few years of his life debunking psychics and mediums) and teen angst that made me hate everything my parents liked, the experience left me convinced that psychics were con artists who separated vulnerable and desperate people from their cash in exchange for poor acting.
In March 1902 in Berlin, police officers interrupted a séance of the German apport medium Frau Anna Rothe. Her hands were grabbed and she was wrestled to the ground. A female police assistant physically examined Rothe and discovered 157 flowers as well as oranges and lemons hidden in her petticoat. She was arrested and charged with fraud. Another apport medium Hilda Lewis known as the "flower medium" confessed to fraud.
Many 19th century mediums were discovered to be engaged in fraud. While advocates of mediumship claim that their experiences are genuine, the Encyclopædia Britannica article on spiritualism notes in reference to a case in the 19th century that "...one by one, the Spiritualist mediums were discovered to be engaged in fraud, sometimes employing the techniques of stage magicians in their attempts to convince people of their clairvoyant powers." The article also notes that "the exposure of widespread fraud within the spiritualist movement severely damaged its reputation and pushed it to the fringes of society in the United States."
