How to guess a Card that has been thought of by any body, by writing before hand on a Paper or Card a Number, which will certainly be that of the Card that has been thought of.
All the preparation of this trick consists in a mathematical combination; here follows the method of operating in order to succeed.
Take a pack of piquet cards, present them to one of the company, desiring him to shuffle them well, and to get them shuffled by whoever he pleases: then make several persons cut them. After which you will propose to one of the company to take the pack, and think of a card, and remember it, as likewise of the number of its order in the pack, by counting one, two, three, four, &c. till he comes inclusively to the card thought of by him. Then offer to go in another room while he is doing what you required, or to be blind-folded, assuring the company that you will declare before-hand, if required, the number of the order in which the card is that has been thought of.
