Bradley, J.

The first question presented is whether there was a valid contract made for the sale of the property by the defendant to plaintiff, and if so, the further question will arise, whether it was an executed one, so as to pass the title to the plaintiff, or was executory merely. As no part of the *277 property was delivered to or received by the plaintiff, and none of the purchase-money paid, as required by the statute of frauds, the sale was void unless a note or memorandum of the contract was made in writing and subscribed by the defendant. (2 R. S. 136, § 3.) The form of the memorandum, as drawn, was 11E. Frank Coe bought of William Tough,” followed by a list of the articles of property in question with prices added. This paper was not, at the end of it, subscribed by the defendant, so that standing alone, whatever view may be taken of its terms, it was not effectual as a contract of sale. (James v. Patten, 6 N. Y. 9.) But it is contended that the note or letter written on the same occasion by the defendant, subscribed by him, and addressed to the plaintiff, may be taken in connection with the first-mentioned memorandum, and the signature to the one treated as subscribed to both, each constituting part of the same instrument. To permit this to be done, so as to relieve it from the operation of the statute, the two papers must have been so physically united, or such reference made by one of them to the other, that they may be construed together as one instrument without the aid of oral evidence. (Baptist Church v. Bigelow, 16 Wend. 28; Wright v. Weeks, 25 N. Y. 153; Drake v. Seaman, 97 id. 230; 27 Hun, 63; Stone v. Browning, 68 N. Y. 598.) . The two papers by their date purport to have been made at the same time, they are in the handwriting of the defendant, relate to the same subject, and the reference to the paper designated as a bill of sale in the one, embraces in figures certain amounts corresponding with those in tho other. They sufficiently referred to the same transaction to permit them to be construed together, and to be given such effect as they were entitled to. (Tallman v. Franklin, 14 N. Y. 584; Peabody v. Speyers, 58 id. 230; Peck v. Vandemark, 99 id. 29.) 'The more difficult question arises upon the consideration of the construction and effect, which may be given to those papers. It has been held that a memorandum in the form of that here designated as a bill of sale, with payment receipted, did not constitute a contract of sale so as to exclude parol evidence of *278 warranty, but was a mere receipt. (Filkins v. Whyland, 24 N. Y. 338.)

While, presumptively, at least, a receipted bill in that form will not have the character of a contract of sale, the effect when no receipt is added may be otherwise. Then it may be-such a contract, or the written evidence of it, within the intention of the parties, and entitled to such effect. (Terry v. Wheeler, 25 N. Y. 520 ; Bonesteel v. Flack, 41 Barb. 435.)

That paper, standing alone, not being subscribed by the defendant, had no validity, and in connection with the other it must be treated as referred to for the purpose indicated by .the terms of the latter, by which the defendant says that “ In order to liquidate and secure you (plaintiff) in the payment of your account as now due, I will propose to do as follows: Bill of sale inclosed $1,520.” And then adds another item of property with two items of cash or notes to make up the amount of $2,520. And after stating the balance of the plaintiff’s account at $1,975, subscribes his name. In aid of the construction of the instrument, reference may be had to the extrinsic circumstances attending the transaction between the defendant and the plaintiff’s agent. The latter called upon the defendant to obtain payment, or security for its payment, of the debt due his principal from the defendant. The interview resulted in an offer of the defendant to sell, and of the agent to purchase, some personal property on account of the debt; and for the purpose of doing so the bill of sale, so-called, was drawn by the defendant, and handed to the agent unsigned.

The note or letter addressed to the plaintiff was written upon the suggestion of the agent that the defendant put on paper a statement, to be taken to the plaintiff, of what had transpired between them. The amount of the prices designated for the articles of property, with that of the proposed cash or notes, was purposely made to exceed the debt, with a view to enable the plaintiff to realize from it the full amount of his account against the defendant. It is not important whether the purpose of the contemplated sale was to pay or *279 secure the payment of the debt. The apparent design, as indicated by the oral evidence, of the transaction, was a sale and purchase, and that the so-called bill of sale was drawn, delivered and received for that purpose. That was not accomplished by it. It is, however, contended that the paper after-wards written, addressed to the plaintiff, and signed by the defendant, was effectual to give to the former the effect of a bill of sale subscribed by the defendant; and that it was not embraced within the executory character of the proposition expressed in the other, but that only the payment or delivery of the cash or notes there mentioned was dependent upon the future action of the defendant. The intention of parties to a written instrument must be derived from it, although its construction may be aided by the light of extrinsic circumstances. When this alleged bill of sale was handed to the plaintiff’s agent, it was ineffectual for any purpose, whatever may have been the design of the parties. It does not appear that the other paper was then in contemplation, and its effect must be ascertained from its terms as they may be construed. In its relation to the former it may be assumed that reference was made to the articles of property there mentioned. But it is difficult to distinguish the application of the offer or proposition of the defendant to any one, from any other, portion of the means mentioned for the payment or security of the debt. It was to “ liquidate and secure ” it as stated. The defendant proposed to do what he had not already done in that respect. He had neither transferred any of the personal property or notes, and had made no contract to that effect. They altogether came within the purpose expressed, and his proposition or promise to accomplish it was in form executory. If the paper called a bill of sale had been independently valid, a different view may have been taken upon construction of the writings. It would,, therefore, seem that the support of the plaintiff’s claim .of title, requires the conclusion that the offer or promise of the defendant to sell to him the property, was or became effectual for that purpose. It is a rule, as relates to personal property, that when by a valid agreement one party unconditionally agrees *280 to sell to another who agrees to purchase, and nothing remains to be done to complete the sale, the contract will be treated as an executed one, and title will pass although no delivery or payment is made. (Olyphant v. Baker, 5 Denio, 379; Terry v. Wheeler, 25 N. Y. 520.) In the present case the proposition or promise of the defendant to sell the property was, by its terms and import, made with a view to the subsequent acceptance by the plaintiff. There cannot, therefore, be said to have been any concurrent undertaking on the part of the latter to purchase.

This proposition, when made, seems to have had no consideration for its support. It was amere offer of a debtor to sell goods to his creditor in payment or security of the debt due the latter, founded upon no new consideration, but resting solely in the purpose, so manifested of the debtor, to pay the debt or secure its payment in that manner.

The conclusion would seem, for that reason, to follow, that a subsequent acceptance would not be effectual to create a valid contract of sale between the parties. (Cooke v. Oxley, 3 Durn. & E. 653; Burnet v. Bisco, 4 Johns. 235 ; Utica & Schenectady R. R. Co. v. Brinckerhoff, 21 Wend. 139; Chicago & G. E. R. Co. v. Dane, 43 N. Y. 240; Macedon & B. P. R. Co. v. Snediker, 18 Barb. 317.) In that respect this case differs from those determined in Burrell v. Root (40 N. Y. 496); Justice v. Lang (42 id. 493; 52 id. 323); Mason v Decker (72 id. 595). In [those cases the offers and promises of the defendants had the support of consideration, arising out of mutuality of agreement or produced in some other manner.

If these views are correct, there was no valid contract made by the defendant for the sale of the property in question to the plaintiff, to support his claim of title.

The judgment should be affirmed.

All concur, except Parker, J., not sitting.
