Fig. 3.—Plan of magic cupboard.
The cupboard is opened, and anybody allowed to mount the stage and see for himself that there is no false bottom or trap in the floor. When he is perfectly satisfied and has returned to his seat, the magician introduces his assistant. At a nod from him she enters the cupboard, which is then closed. The wizard makes a few mystic passes with his wand, utters the words “Imshi! Imshi!” meaning in Arabic, “Depart! Depart!” The cupboard is then opened and—found to be empty!
Once more the doors are closed. The magician reverses his passes, claps his hands, looks upward, and again opens the doors. The pretty young lady stands inside, smiling radiantly!
The mystery is understandable by a glance at [Fig. 3]. At E and F are hinged two mirrors, identical in size with the walls of the cupboard. When opened inwards these mirrors meet at the post, H, which serves to conceal the line of their meeting.
Now the whole deception lies in the walls of the cupboard. When inspected by the audience the two mirrors were flush against their respective sides, and, having their backs covered with the same paper used to line the whole interior of the cupboard, they were mistaken for the real walls against which they were pressed. But when the mirrors are opened inwards the spectator can see only the reflection of the actual walls cast upon the mirrors in such a way that he imagines he sees the back of the cupboard. Of course this is really hidden from him by the opened mirrors, but they reflect the paper-lined walls so accurately that a discovery of the deception is impossible.
When the lady is introduced into the cupboard the mirrors stand flat against the sides of the box, which is really empty, but as soon as the magician closes the outer doors upon his assistant, she pulls out the sides, shuts herself into the triangle E, H, F, and awaits the opening of the cupboard. When this takes place the mirrors are, of course, in the position indicated by [Fig. 3]. The spectators, seeing in them the reflection of the walls, think they see the back E, F, and thereby conclude that the box is empty. This process is reversed when the lady makes her reappearance.
