For every handicap for which there is a penalty clause, the handicapper shall append to the weight the day and hour in which winners will be liable to a penalty, and no alterations shall be made in any handicap after publication except in case of omission through error of the name or weight of a horse duly entered, in which case, by permission of the stewards, the omission may be rectified by the handicapper.
