“ It would prove that there never was any concluded, binding contract entitling the party who claimed the benefit of it to enforce its stipulations. The exclusion of parol evidence of such an agreement could be justified only upon the ground that the mere possession of a written instrument, in form a promissory note, by the person named in it as payee, is conclusive of his right to hold it as the absolute obligation of the maker. ”

“ While such possession is, undoubtedly, prima facie-indeed, should be deemed strong-evidence that the instrument came to the hands of the payee as an obligation of the maker, enforceable according to its legal import, it is open to the latter to prove the circumstances under which possession was acquired, and to show that there never was any complete, final delivery of the writing as the promissory note of the maker, payable at all events and according to its terms. ”

“ A written contract must be in force as a binding obligation to make it subject to this rule. Such a contract cannot become a binding obligation until it has been delivered. Its delivery may be absolute or conditional. If the latter, then it does not become a binding obligation until the condition upon which its delivery depends has been fulfilled. If the payee of a note has it in his possession, that fact would be prima facie evidence that it had been delivered; but it would be only prima facie evidence. The fact could be shown to be otherwise, and by parol evidence. ”
