Take a pack containing fifty-two cards, then lay out one card, any card
you see proper. Then divide the cards into three rows, by laying them
down face upwards. When you have laid down three begin at the left and
lay one upon the first, so continue to the right until you have laid out
the fifty-one; at the same time request some person to think of a card.
When they are laid out, ask which parcel the card is in; he tells you,
place that parcel in the middle of the other. This done, lay them out
again in three parcels; so continue to do for four times, and the card
he thought of will be the twenty-sixth card.
