TO TELL FOUR CARDS IN A LOOKING-GLASS.

Prepare a pack of cards thus: eight aces of diamonds, eight eights of clubs, as many tens of hearts, and a last octave of queens of spades. These sets are arranged in the order as described, the last bottommost.

The four persons who draw are forced to select each from a set of eight, in order from the top downwards. Do not allow the drawers to look at the cards, but keep them in their hands or pockets. You now hand around a mirror, and ask the spectators whether they see in it anything else except their own faces. On their replying in the negative, you say, with an air of mystery, that you can see something else in it, and then call off, as if out of the mirror, the card which each person has drawn.
