201. While receiving communications from my spirit sister, the table tilting toward the medium, so as to cause the cord actuating the index, by being through a string tied to a weight on the floor, alternately to be withdrawn and returned, consequently, winding off and on the pulley which turned the index, I suggested that the relative position of the medium should be reversed, so that she should be on the same side with the apparatus. By this change the table would have to rise under the hands of the medium. The proposed modification was successfully carried out. 202. I asked my sister how a spirit could work an apparatus with the medium’s hands on the upper surface of the table; the reply was, that the presence of the hands of the medium enabled the spirit to act in opposition to them. 203. Under this head comes the experiment in which a board was supported so as to turn on a fulcrum, one foot of the board being on one side of the fulcrum, and three feet on the other, the longer end suspended on a spring balance. When a medium, eleven years old, placed his hands on the short end, that end rose while the other, of course, went down; in some instances, showing an increase of downward pressure on the balance, equivalent to seven pounds. 204. This experiment was subsequently repeated at my laboratory, in the presence of John M. Kennedy, Esq. Having a basin of water on the board, the boy’s hands being merely immersed in the water, and not touching the parietes of the containing vessel; the balance was affected as in the experiment above described, although not to so great an extent. 205. In one case, Mr. Kennedy satisfied himself, that the medium did not touch the vessel, by placing his own hands below those of the medium. 206. My much-esteemed friend, Prof. Henry, having treated this result as incredible, I was induced to repeat it with the greatest precision and precaution, as represented in Plate 3. The board, as already described, being about four feet in length, is supported by a rod as a fulcrum at about one foot from one end, and, of course, three feet from the other; a glass vase, about nine inches in diameter and five inches in height, having a knob to hold it by when inverted, had this knob inserted in a hole made in the board, six inches nearly from the fulcrum. Thus, the vase rested on the board, the mouth upward. A wire-gauze cage, such as is used to keep flies from sugar, was so arranged by well-known means, as to slide up or down on two iron rods, one on each side of the trestle supporting the fulcrum. By these arrangements it was so adjusted as to descend into the vase until within an inch and a half of the bottom, while the inferiority of its dimensions prevented it from coming elsewhere within an inch of the parietes of the vase. Water was poured into the vase so as to rise into the cage till within about an inch and a half of the brim.
