A person draws four cards from the pack, and you tell him to remember
one of them. He then returns them to the pack, and you dexterously place
two of them under, and two on the top of the pack. Under the bottom ones
you place four of any sort, and then taking eight or ten from the bottom
cards, you spread them on the table, and ask the person if the card he
fixed on is amongst them. If he says No, you are sure it is one of the
two cards on the top. You then pass those two cards to the bottom, and
drawing off the lowest of them, you ask if that is not his card. Should
he again say No, you take up that card, and bid him draw his card from
the bottom of the pack. But if, on the contrary, he says his cards are
amongst those you first drew from the bottom, you must dexterously take
up the four cards you put under them, and place them on the top. The
other two are the bottom cards of the pack, and are to be drawn in the
manner before described.
