subsequently drew up the opinion of the Court. The single question in this case is, whether the property in the note, which is the subject of the action, had vested in the plaintiff at the time of the demand and refusal. The Court are all of opinion that it had not. The transaction was inchoate and incomplete, and until the exchange was made pursuant to the agreement, the old note was not discharged, nor did the plaintiff become entitled to the right of property in the new one. It was a proposition, an executory agreement, never in fact executed. It is impossible to consider Miles Bartholomew as the agent of the plaintiff; he was himself a promiser and a party, and the same act of delivery which would bind his son would bind him, and till such a delivery as would bind him, his son would not be bound. It was a joint obligation, and must take effect, to bind both at the same moment. He was undoubtedly the agent of his son, authorized to deliver the note for him, and had he so delivered it, pursuant to that authority, the son would have been bound.

Such was the view taken of the case in the first instance, and an opinion was about to be delivered. But the facts were rather imperfectly stated, and a slight doubt arose in the minds of some of the Court,- which led to a delay and further inquiry. It was on this ground: it did not appear by the report, in th j first instance, what was the date and amount of the old note, for which the new note was to be given in exchange. Now, if the new note was given for the precise amount due on *255the old one, that is, for the principal of the old one with the interest computed from the date of the old to that of the new, so that nothing remained to be done, and the new note was, by mutual agreement, left at a particular place for the plaintiff, so that nothing remained but for him to call and take it, — under the rule of law in Massachusetts, that a negotiable note is to be . deemed prima facie payment of a pre-existing simple contract debt, this new note thus deposited, might be considered as de facto payment and satisfaction of the old note, by which it was cancelled and extinguished, and all right of action upon it taken away, and if so, it would follow as a necessary consequence, that the plaintiff must be deemed to have a property in the new note.

But upon comparing the two notes, the fact appears, as a* first supposed, but not stated, that the new note was given foi the same principal' as the old, and that, therefore, there was interest due on the old note, and it is to be presumed, that upon the exchange of the notes, the interest was to be paid. This renders it quite decisive, that independently of the question upon the fact of delivery, it could not have been understood by the parties, that the new note was to enure and operate de facto, as payment of the old one, or that the new note was left with Miles Bartholomew for any other purpose than to be exchanged for the old one, that is, to be delivered when the old one should be given up. The further, consideration, that the interest was to be paid on the old note, on such exchange, renders it quite clear, that the transaction was not to be understood as closed, so as to vest the property in the new note its the plaintiff, until such exchange, which was never made.
