To Change The Cards Which Several Persons Have Drawn From The Pack
On the top of the pack put any card you please--suppose the queen of
clubs; make the pass, bring that card to the middle of the pack, and
offer it to a person to draw. Then, by cutting the cards, bring the
queen again to the middle of the pack. Make the pass a second time,
bring it to the top, and shuffle the cards without displacing those on
the top. Make the pass a third time, bring it to the middle of the
pack and o
distance from the first person, that he may not perceive it is the
same card. After the like manner let five persons draw the same card.
Shuffle the pack without losing sight of the queen of clubs, and,
laying down four other cards with the queen, ask each person if he see
his card there? They will all reply, "Yes," as they all drew the queen
of clubs. Place four of those cards on the pack, and, drawing the
queen privately away, you approach the first person, and showing him
that card, so that the others cannot see it, ask if that be his card;
then patting it on the top of the pack, blow on it, or give it a
stroke with your hand, and show it in the same manner to the second
person, and so of the rest.
