TO CHANGE A CARD BY WORDS.

You must have two cards of the same sort in the pack, say the king of spades. Place one next the bottom card (say seven of hearts), and the other at top. Shuffle the cards without displacing those three, and show a person that the bottom card is the seven of hearts. This card you dexterously slip aside with your finger, which you have previously wetted, and taking the king of spades from the bottom, which the person supposes to be the seven of hearts, lay it on the table, telling him to cover it with his hand.

Shuffle the cards again, without displacing the first and last card, and shifting the other king of spades from the top to the bottom, show it to another person. Yon then draw that privately away, and taking the bottom card, which will then be the seven of hearts, you then lay that on the table and tell the second person (who believes it to be the king of spades) to cover it with his hand.

You then command the cards to change places; and when the two parties take off their hands and turn up their cards, they will see, to their great astonishment, that your commands are obeyed.
