Supreme Court of Pennsylvania September 15, 1848 (Mevey v. Matthews)

Rogers, J.

There is no reason for any exception to the testimony, on the ground of interest; for the plaintiff offered to prove by the witness that he was the principal, and the other defendants sureties. His evidence is against himself, because it throws the debt on himself as the principal, without the right of contribution from the other defendants, who were but sureties.
