There is no error in this record of which the appellant has reason to complain. The court below narrowed the margin of fact upon which the jury could base a verdict beyond what the case in our judgment warranted, but of this the appellant cannot complain. It was well observed in Phillips v. Meily, 106 Pa. 536, by the then Mr. Justice Paxson, that “ The English rule that parol evidence is inadmissible to vary the terms of a written instrument does not exist in this state. The cases are numerous upon this point. It is sufficient to refer to Kostenbader v. Peters, 80 Pa. 438. It would perhaps be more accurate to say that the rule has been relaxed, for the guards which this court has thrown around the modification of the rule have to some extent preserved the rule itself. In the present condition of the law of evidence public policy requires that we should do nothing to increase the facilities for destroying written instruments. As was well observed by our Brother Trunkey in the recent case of Juniata Building and Loan Association v. Hetzel, 103 Pa. 507, ‘Now that parties are competent witnesses each may oppose his oath to the other’s, and certainly when written contracts or obligations are sought to be impeached by defenses purely equitable the reason is stronger than formerly for enforcing the rules of evidence applicable to cases in equity.’ ” The rule above stated has prevailed in Pennsylvania since Herr, Lessee, v. Kirkbride, tried at nisi prius in Bucles county, March 24, 1773, which case was authoritatively reported by Mr. Chief Justice Tilghmait, in his opinion in Wallace v. Baker, 1 Binney, 610.
It was not necessary, however, to invoke this rule in the present case. It is not the case of a written instrument varied in its effect by parol testimony. It is admitted by the appellant that the letter of the 8th of September was not the contract. It is sought however to bind the appellee by the letter of the 15th of September, 1890, and by a subsequent agreement for the sale of a lot and the erection of a house dated the 10th of January, 1891, which became executed by the deed of the appellant to the appellee and the mortgage of the appellee and wife to the appellant dated the 2d of February, 1891, and to exclude entirely all that led to and induced these written evidences of a broader and more comprehensive contract. The
It follows, from what we have said, without further discussion, that the court could not have properly answered any of the appellant’s points as requested, denying the right of the plaintiff in the court below to recover. The assignments of error are therefore all overruled and the judgment is affirmed.
