(_ii_) Another mode of testing is that illustrated in Plate II., where a plate upon two balls supports the hands of the medium, and forms the only means of conducting communication between the medium and apparatus. It may be easily conceived that instead of the hands being placed upon the board, the plate and balls being interposed, the hands of the medium may be supported over the board of Fig. 2. as they are represented to be supported over the table in Fig. 1, Plate II. See 167, 169, 172, 177, 196. (_kk_) FIG. 3, Plate IV., is a representation of an association of serrated strips of iron in a wooden frame, which sliding on the lever board of Fig. 1, so as to have the saws just above the back of the hand of the medium, is found to increase the efficacy of the mediumship. It is only of importance to use it when test conditions are requisite, as explained already, Fig. 1, (_hh_). The rationale, so far as it can be suggested, will be stated under the head of mediumship. It will be perceived that the size of the frame is not in due proportion to the lever board, being upon a larger scale. But this renders it more conspicuous, and the reader can easily conceive its size to be such as to allow the grooves in the wooden sides of the frame to receive the edges of the lever board _L_, and thus to be secured firmly thereupon.
