1. At the time when the instrument of writing, set out in the declaration, was made, it was not entitled to be considered as a sealed writing, because there was no seal, nor its' equivalent, a scroll, appended to the signature. Lee v. Adkins, Minor, 187. The declaration in as-sumpsit is,-therefore, the proper one, unless the remedy is changed by the act of 1839. This directs, that all covenants, conveyances, and all contracts iri writing, which impoi’t on their face to be under seal, shall be taken, and held to be sealed instruments, and shall have the same effect as if the seal of the party or parties were affixed thereto, whether there be a scrawl to the name of the party or parties or not. P- P- 99. It is of very little importance in the aspect on which this case is presented, whether the plaintiff has his remedy by action of as-sumpsit or covenant; but if more time had elapsed, the construction of the statute of 1839, might materially affect the rights of the defendant; and we apprehend either party can properly insist that it shall receive such a construction as will not affect pre-existing contracts.
If the remedy alone was affected by this enactment, no injury could arise by giving it a retrospective operation; butsdch does not appear to have been the intention of the legislature; the mischief was, that instruments similar in appearance, produced different legal consequences, by the addition or omission of a very unimportant matter; this was intended tobe remedied, and full effect can be given by a prospective operation. If it is retrospective in its operation, then it is evident, that in another condition of time, the defendant’s right, under the statute of limitations, would be affected; it is also evident, that by such a construction, the plaintiff’s action would be changed from assumpsit to covenant or debt. We are satisfied that the statute has no other than a prospective operation ; and, therefore, the action of assumpsit was the proper one on this instrument.
2. There is but little question that the introduction of the *147super se assumpsit in this declaration, is improper, according to the strict rules of pleading, because, a legal obligation to pay the sum stipulated, did not arise from the promise contained in this contract; we think it is probable that the plaintiff is only entitled to the value of the land, as the proper measure of damages; without, however, undertaking at this time to decide this question, it can be said, that whatever may be the true measure of damages, the improper introduction of the super se assumpsit, cannot be reached by a general demurrer, in those cases where it can be stricken from the declaration, and enough remain to constitute a good cause of action. Castles v. McMath, 1 Ala. Rep. N. S. 326; Evans v. Watrous, 2 Porter, 205. But the introduction of a super se assump-sit, cannot have the effect to change the liability of the defendant, or authorise a judgment for a stipulated sum, when that, in reality, is in the nature of a penalty.
If the super se assumpsit clause is stricken out of this declaration, enough remains to constitute a good cause of action, as it contains the contract, and a sufficient averment of its breach.
Let the judgment be reversed, and the case remanded.
