The general issue in trespass on the case, in the species of assumpsit. Its form is, "And the said C D, by E F, his attorney, comes and defends the wrong and injury, when, etc., and says, that he did not undertake or promise in manner and form as the said A B, hath above complained. And of this he puts himself upon the country."
Under this plea almost every matter may be given in evidence, on the ground that as the action is founded on the contract, and the injury is the nonperformance of it, evidence which disaffirms the obligation of the contract at the time when the action was commenced goes to the gist of the action.
