Subscribers to sweepstakes may, before the time fixed for naming, transfer the subscription, but a person making an entry under another subscription when forfeit must be declared by a particular time, shall be considered as having taken the engagement upon himself, and it shall be transferred to his name. Also before the time fixed for closing an entry of a horse in any race may be corrected, or another horse may be substituted but a subscription cannot be withdrawn.
