In the supposition that the person who thinks of the card will stop at number 13, and that thirteenth card is the queen of hearts. Supposing again that the number you have marked or designed before-hand is number 24; you will return in the room in case you had left it; or desire the handkerchief, to be taken off, if you have been blind-folded; and, without asking any question of the person who has thought of the card, ask only for the pack, and apply it to your nose as if to smell it; then passing it behind your back, or under the table, you must take, beginning from the bottom of the pack, twenty-three cards, that is to say, one less than the number you had designed before hand; then place those twenty-three cards on the top of the remainder; you must take particular care not to put one more or less, for that would prevent your success. This being done, you are to return the pack to the person who has thought of the card, recommending him to reckon the cards from the top of the pack, beginning by the number of the card he thought of. His card being the thirteenth, he will be obliged to count fourteen, and you are to flop him when he comes to twenty three, telling him that the number you have designed is twenty-four, and that consequently the twenty-fourth card which he is going to take up will be the queen of hearts, and it will be exactly the case. CHAP. XIV. _A mathematical Combination for guessing, in a whole pack composed of fifty-two Cards, how many Points will make the Cards under each Parcel, which Parcels are to be made by one of the Company, observing to him that each Parcel he makes is to compose the Number of Thirteen, to begin from the Point of the first Card which he takes to form each Parcel._ EXAMPLE. The pack having been shuffled by one or more persons, make it be cut by as many persons as you think proper. Then desire one of the company to form the parcels of cards, all which must contain thirteen each, beginning by the first card he takes up. Suppose that this first card is a nine, the next will be called ten, and so on till thirteen; consequently this first parcel will be composed of five cards 5 If the next card should be an ace, the ace counting only one, the next parcel will therefore be composed of thirteen cards 13 Suppose the next card is a court card, or a ten, they being of the same value, this parcel will contain, in order to make up thirteen, four cards 4 If the following should be a five, then the fourth parcel will contain nine cards 9 Should the next parcel be a seven, the fifth parcel will be composed of seven cards 7 A court card being the first of this parcel, it will be composed of four cards 4 If the seventh begins by an eight, it will be composed of six cards 6
