An ingenious improvement has been made to this hand-test by an American conjurer, one that enables the medium to produce the hand although his feet are secured by the sitter. "Be kind enough, sir," says the performer to the investigator, "to place your feet on mine. If I should move my feet ever so little, you would know it, would you not?" The sitter replies in the affirmative. The medium, as soon as he feels the pressure of the sitter's feet, withdraws his right foot from a steel shape made in imitation of the toe of his boot, and operates the spirit hand at his leisure. After the sitting, he of course, inserts his right foot into the shape and carries it off with him. The production of spirit music was one of Home's favorite experiments. There are all sorts of ways of producing this music, the most ingenious of which I give: The apparatus consists of a small circular musical box, wound up by clock work, and made to play whenever pressure is put upon a stud projecting a quarter of an inch from its surface. This box is strapped around the right leg of the medium just above his knee, and hidden beneath the trouser leg. When not in use it is on the under side of the leg. On the table a musical box is placed and covered with a soup tureen, or the top of a chafing dish. When the spectators are seated, the medium works the concealed musical box around to the upper part of his leg near the knee cap, and by pressing the stud against the under surface of the table, starts the music playing. In this way the second musical box seems to play and the acoustic effect is perfect. Perhaps Home used a similar contrivance; Dr. Monck did, and was caught in the act by the chief of the Detective Police. Home during his séances on the Continent of Europe was accused of all sorts of trickery. Some asserted that he had concealed about him a small but powerful electric battery for producing certain illusions, mechanical contrivances attached to his legs for making spirit raps, and last but not least, as the medium states in his "Memoirs:" "they even accused me of carrying a small monkey about with me, concealed, trained to perform all sorts of ghostly tricks." People also accused him of obtaining a great deal of his information about the spirits of the departed from tombstones like an Old Mortality, and bribing family servants. A more probable explanation may be found perhaps in telepathy.
