64. If the dealer's partner, by touching a card or otherwise, suggest the play of a card from dummy, either of the adversaries may, but without consultation, call upon the dealer to play or not to play the card suggested.
65. Dummy is not liable to the penalty for a revoke; and if he should revoke and the error be not discovered until the trick is turned and quitted, the trick stands good.
66. A card from the dealer's hand is not played until actually quitted; but should the dealer name or touch a card from the dummy hand, such card is considered as played, unless the dealer in touching the card or cards says, "I arrange," or words to that effect.
CARDS EXPOSED BEFORE PLAY
67. If, after the deal has been completed and before the trump declaration has been made, either the dealer or his partner expose a card from his hand, the eldest hand may, without consulting with his partner, claim a new deal.
68. If, after the deal has been completed and before a card is led, any player shall expose a card, his partner shall forfeit any right to double or re-double which he otherwise would have been entitled to exercise; and in case of a card being so exposed by the leader's partner, the dealer may either call the card or require the leader not to lead the suit of the exposed card.
CARDS EXPOSED DURING PLAY
69. All cards exposed by the dealer's adversaries are liable to be called, and such cards must be left face upward on the table.
70. The following are exposed cards:
| 1st. | Two or more cards played at once. |
| 2d. | Any card dropped with its face upward, or in any way exposed on or above the table, even though snatched up so quickly that no one can name it. |
| 3d. | Every card so held by a player that his partner can see any portion of its face. |
