PART VII.

THE "ONDULÉES," OR WAVY CARDS.

The above marks, or waves, are also made whilst playing.

When the Greek observes any cards, which will suit him to perform the trick he is about to play, he makes, at the bottom of the left-hand corner, a little fold, or arch, inwards. This alteration, be it ever so slight, produces a kind of lustre on the card, which the eye of the Greek can immediately detect.

This trick is generally employed in cheating at Piquet. The Greek, in this way, marks all the aces and high cards in any of the suits.

With certain arts of _legerdemain_, which I have before alluded to, he can so arrange all, or part, of his hand, that no play of his adversary, be it ever so good, could stand against it.
