It is to be added that the change of the plain glass for the other replaces the performer before the eye, for, indeed, he has not stirred.
THE ENCHANTED TELESCOPE.
In this variation of the Nostradamus Trick, a telescope-tube is mounted, instead of the false mirror, on a stand on a table. It has a plane mirror set in it at an angle of forty-five degrees over the stand, which is hollow and communicating with a drawer of the table, opening into the next room, with a second plane mirror, to reflect any person therein, up to the tube reflector.
The inner room should be dark, so that, when the light is cut off, the figure will vanish.
THE HEAD OF JOHN THE BAPTIST.
Before a concave mirror, which the spectator sees, have a little railway with a head on a dish, in wax or plaster, strongly illuminated, and concealed from him. Let a wire in the hands of an assistant, or wound on a drum by the release of a detaining spring, draw this head on its carriage into the focus of the mirror, when it will seem to start out and fly towards the beholder.
THE DAGGER OF MACBETH.
A table is shown on which is a looking-glass. The room is darkened, when a white arm and a hand brandishing a dagger is seen suddenly to appear and menace the spectator.
Explanation.—The glass of the mirror slides out of the frame at a signal. Behind it is a concave mirror set on the floor at an angle in an opening in the wall. Within the other room an arm and hand of wax, holding a dagger, are mounted so as to descend, while brilliantly illumined, towards the concave mirror.
