87. If any one (not being Dummy) omit playing to a former trick, and such error be not discovered until he has played to the next, the adversaries may claim a new deal; should they decide that the deal stand good, or should Dummy have omitted to play to a former trick, and such error be not discovered till he shall have played to the next, the surplus card at the end of the hand is considered to have been played to the imperfect trick, but does not constitute a revoke therein.
88. If any one play two cards to the same trick, or mix a card with a trick to which it does not properly belong, and the mistake be not discovered until the hand is played out, he (not being Dummy) is answerable for all consequent revokes he may have made. If, during the play of the hand, the error be detected, the tricks may be counted face downwards, in order to ascertain whether there be among them a card too many: should this be the case they may be searched, and the card restored; the player (not being Dummy) is, however, liable for all revokes which he may have meanwhile made.
The Revoke.
