[Fig. 2] shows the frame as seen from behind. The door, P, is seen open, and at S is seen the sand falling between the two glasses. In the section at the side, V and V are the two glasses, P, the door, and R, the reservoir.
Another experiment may be made by means of a small standard on a foot, A, upon which a spectator has placed the seven of hearts. The card passes into the frame. To tell the truth, it is removed by the cover, C, along with the thin disk, D, that covered the foot, A, and upon which it was placed. It will be said that we have here to do with a double bottom. Allow the cover, C, before covering the card, and the foot, A, after the experiment is finished, to be examined. Is the cover asked for again? One will hasten to show it without saying that the back edge of the table has just been struck with it in order to cause the disk, D, and the card to fall on to the shelf.
HOUDIN’S MAGIC BALL.
This ball, which was recently seen in a toy shop, has the aspect, externally, of the one used in the familiar toy known as the “cup and ball.” Extending through its center there is a straight cylindrical aperture, and when a cord is passed through the latter, the ball easily slides along it.
