delivered the opinion of the Court.
The general principle on which the defendant’s counsel rely is correct, as to the mode of proving the execution of deeds and other contracts where there is a subscribing witness. The only question is whether it is applicable to a person in the character and situation in which Smith, the witness, stood when he testified respecting his signature on the paper produced by the plaintiff’s counsel. We admit that if Smith had not been introduced as a witness by the defendant, and had not testified as to certain charges stated in the account, for the purpose of proving the alleged want of consideration for the note declared on, it would not have been competent for the plaintiff to examine him as to the fact of his having signed the paper or contract before mentioned. Smith, being called by the defendant, testified relating to the hire of oxen and paying for wintering the same, mentioned in said account. The paper appeared to be a contract between the plaintiff and Sm,ith respecting the same hire and wintering of oxen charged in said account. The object in view in introducing the agreement was to shew that Smith had acknowledged the facts, respecting the above charges to he different from his testimony. When, therefore, Smith acknowledged that' the paper or agreement was signed by him, and was genuine, he acknowledged the contents of the paper, as therein stated, to be true ; such an admission merely made by Smith was evidence on common principles, as it tended to impeach Smith, by shewing either ' his want of veracity or the incorrectness of his memory ; and we cannot perceive that such admission is less proper or effectual because he was on oath when he made it. it was not offered as the basis of *96any claim on the part of the plaintiff, but for the purpose of repelling the defence, by shewing the contradictions of the witness brought forward to sustain it. We place the decision of this cause on the special character and circumstances in which Smith was placed; considering his testimony in respect to the paper and his signature merely in the light of admissions or declarations made by Smith, and inconsistent with his previous testimony. We are all of opinion that there must be
Judgment on the verdict.
