40. If, whilst dealing, a card be exposed by either of the dealer's adversaries, the dealer or his partner may claim a new deal. A card similarly exposed by the dealer or his partner gives the same claim to each adversary. The claim may not be made by a player

41. If, in dealing, one of the last cards be exposed, and the dealer completes the deal before there is reasonable time to decide as to a fresh deal, the privilege is not thereby lost.
42. If the dealer, before he has dealt fifty-one cards, look at any card, his adversaries have a right to see it, and may exact a new deal.
43. Should three players have their right number of cards—the fourth have less than thirteen, and not discover such deficiency until he has played any of his cards, the deal stands good; should he have played, he is as answerable for any revoke he may have made as if the missing card or cards had been in his hand; he may search the other pack for it, or them.
44. If a pack, during or after a rubber, be proved incorrect or imperfect, such proof does not alter any past score, game, or rubber; that hand in which the imperfection was detected is null and void; the dealer deals again.
45. Any one dealing out of turn, or with the adversary's cards, may be stopped before the last card is dealt, otherwise the deal stands good, and the game must proceed as if no mistake had been made.
