18.—If an Umpire erroneously calls "fault" and at once corrects himself and cries "play," and the striker-out tails to return the ball, a "let" must be allowed.
19.—If the ball in play (other than a service) strikes any part of the net or its supports, or the centre stay, no matter how low down (provided it does not touch the ground), and eventually goes over into the proper Court, it is a good return.
20.—If in a double game the Server's service strikes either of his opponents, he wins the stroke.
21.—If a match is postponed on account of rain or darkness coming on, or for any similar reason, and is continued on the subsequent day, the match shall be resumed from the point where it was discontinued on the previous day. An entirely new commencement may only be made with the consent of the Referee.
22.—If two players in a handicap play at the wrong odds, the match stands, unless they have been wrongly instructed by the referee, or any person or persons acting under his instructions, in which case the loser may claim to have the match replayed, unless the mistake in the odds has been in his favour. Such claim must be made within a reasonable time.
23.—A similar decision must be given if two players neglect to play advantage sets when one of the conditions of the event in which they are competing is that advantage sets should be played.

The number at the left of the horizontal columns denotes the player who goes back to scratch, those at the head of the vertical columns the player who still receives odds; and the numbers within the columns show the odds to be received by the player whose number stands at the head of the column:
