Latin. By performing that to the superior which by law he is bound to perform. This refers to the duties of the vassal. He is bound, on claiming an entry, to perform the service or pay the non-entry duties, relief, &c., which under his title the superior has a right to demand on such an occasion ; and a charge by the heir upon the superior, charging the latter to enter him as vassal, may be suspended on the ground of the failure in such performance or payment.
