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.
