COVENANTS PERFORMED, pleading. In Pennsylvania, the defendant may plead
covenants performed to an action of covenant, and upon this plea, upon
informal notice to the plaintiff, he may give anything in evidence which he
might have pleaded. 4 Dall. 439; 2 Yeates, 107; 15 S. & R. 105. And this
evidence, it seems, may be given in the circuit court without notice unless
called for. 2 Wash. C. C. R. 456.
