In some of the cases in which it is said that extrinsic evidence is inadmissible to contradict the recital of a valuable consideration in a contract so as to render it inoperative in law, the contract was under seal.1 Contracts of this sort are governed by principles different from those which apply to simple executory contracts. At common law in the classic period a contract under seal was valid and enforceable without a valuable consideration.2
