delivered the opinion of the court. The only question is, whether the demurrer to the plea is well taken. No authorities were cited upon the argument to show that a specialty could be invalidated for any other cause than the illegality of the consideration, which makes *179it void from the beginning. In this case, the consideration for the bill, or sealed obligation of the defendant, was a slave sold to him by the plaintiff. This was a fair, legal, and valid consideration. In the case of Dorlan v. Sammis,* decided in this court, it was held, that the want or failure of consideration could not be set up at law to impeach a specialty.. The principle on which that decision was founded, applies to the present case. It has been repeatedly decided that the breach of a written warranty as to the quality of goods sold, cannot be pleaded in discharge of a bond given for the consideration.— Much less ought parol representations, as to the quality of a thing, made antecedent to the contract, though false and fraudulent, and though they may have induced the defendant to make the purchase, be pleaded in avoidance of specialty. Whether the plaintiff must seek his remedy at a court of equity, or whether an action at law be *180maintainable on the case disclosed in his plea, need,not now be determined. We are of opinion that the special case set forth in the plea forms no valid defence to this slIit, and that the plaintiff is therefore entitled to judg-

Judgment for the plaintiff.
