The plaintiff, a manufacturer of hatters’ furs, for many years has been a purchaser of hareskins from which are *121clipped the fur used in the manufacture of hats. The defendants, composing the firm of Carlowitz & Co., are merchants in China hareskins, with offices in several cities of China, where such skins are produced for export. They have sold China hareskins to the plaintiff at various times since 1925 through Bingham & Co., their selling agent in the United States.
The controversy which has resulted in this litigation arises out of three contracts for the sale to the plaintiff of raw China hareskins, each of which forms the basis of a separate cause of action contained in the complaint for alleged breach of warranty. In connection with these sales three written contracts were executed by the parties, dated December 13, 1928, January 11, 1929, and January 14, 1929. These contracts are identical in form. The first contract in point of time will, therefore, serve as illustrative of all. It provides:

The contract of January 11, 1929, in similar form, is for the sale of 150,000 skins, which are described as “ Raw China Hareskins, 95% No. 1 ■— 5% No. 2 winter hair, Type A; ” that of January 14, 1929, is for 50,000 skins, described as “ Raw China Hareskins, 80% No. 1 •— 20% No. 2, winter hair.” On the face of each contract appears the following: “All correspondence should be addressed to the firm and not to individuals. Contracts not binding unless signed by the firm.”
The present action is for damages for breach of a warranty alleged to have been given by representatives of Bingham & Co. early in December, 1928, to the effect that the No. 1 quality skins would yield four pounds and the No. 2 quality skins two and two-thirds pounds of fur, for each one hundred skins; furthermore, that both No. 1 and No. 2 quality skins would be delivered flat, with the pelt uncracked and free from sand. These warranties are not contained in the contracts of sale, as the plaintiff appears to have realized, for in its bill of particulars it sets forth that the agreements were partly oral and partly written, the written portion corresponding to the written contracts of sale, and that, except as contained in the written contracts, the warranties were oral.
The plaintiff’s cause of action depended upon its ability to establish that the merchandise delivered was not in accordance with the contracts of sale. For that purpose the plaintiff was entitled to establish the meaning of “ No. 1 ” and “ No. 2 ” hareskins, of “ winter hair ” or “ Type A.” To do this, parol evidence was, of course, proper and necessary. (Emmett v. Penoyer, 151 N. Y. 564; Walls v. Bailey, 49 id. 464; Dana v. Fiedler, 12 id. 40; Gumbinsky Bros. Co. v. Smalley, 203 App. Div. 661; affd., 235 N. Y. 619; Newhall v. Appleton, 114 id. 140; American Aniline Products, Inc., v. Mitsui & Co., Ltd,., 190 App. Div. 485.) But beyond this the plaintiff should not have been permitted to go. If the hare-*123skins delivered were in accordance with the written contracts as thus explained, then the plaintiff was not entitled to recover, even if they were not in accordance with the parol warranty. The court should, therefore, have limited the proof on this point to the meaning to be attributed to these provisions of the written contracts. (Lossing v. Cushman, 195 N. Y. 386, at p. 389.) This was not done. The plaintiff’s president was permitted to testify that the defendants had verbally warranted that the No. 1 and the No. 2 skins delivered under the contracts would yield, respectively, four pounds and two and two-thirds pounds of fur to each one hundred skins. After testifying to the yield of fur ordinarily to be expected from No. 1 and No. 2 skins of type A quality, he testified to conversations early in December, 1929, with Mr. Perry, a salesman of Bingham & Co.: “ Mr. Perry came to the office and offered us another lot of China hareskins, and I said ‘ No,’ I would not buy any further quantities of China hareskins; that the yields had not been holding out and I would only buy on the strength that Mr. Perry would guarantee the yield.” He testified that a few days later Mr. Perry returned with Mr. Skinner, the vice-president of Bingham & Co., who then consented to make this guaranty or warranty of yield. This evidence was received upon the theory that if the defendant might explain the meaning of the trade symbols which the contract contained, the plaintiff was entitled to establish an express warranty, to which the written contract made no reference. In receiving this evidence the trial court said: “ If the contract is not complete in one respect, it is not a complete contract and therefore it does not prohibit the oral testimony rule.” And again the court ruled: “ Explaining is a modification. It is something in addition thereto. I may be a little bit non-techhical in saying ‘ modification.’ You are certainly calling upon the doctrine of parol evidence yourself to explain your own contract. * * *
The same contract prepared by you, you say that you need parol evidence to show what type A is. You need parol evidence to show what quality 1, quality 2, are. Then I say that they must have the same right to show what the contract was.”
We think that there was error in these rulings and also in the charge of the court submitting to the jury the issue of the existence of an express warranty of quality. The testimony to which we have referred had no relation to the meaning attributable to the written contracts nor to any question of implied warranty. Its effect was to extend the defendants’ obligations under the contract by requiring them to deliver not merely skins as therein described but skins which in addition would yield the specified quantity of fur. It was one thing to allow the symbols descriptive of the mer*124chandise to be translated into intelligible terms for the consideration of the jury and quite another to receive proof of an express parol warranty of the merchandise so described. The first involved an explanation; the second, an extension of the written contract. The court also in its charge very carefully discriminated between the import of the written contracts and the existence of an express warranty, but erroneously submitted both questions to the jury. After stating the contentions of the parties concerning the meaning of the written contracts, the court charged: “ However, the plaintiff goes further and alleges that there are express warranties of quality in this case. I charge you that if Mr. Perry and Mr. Skinner did have such authority to make the express warranties as claimed by the plaintiff, and they did say that these sldns would be of the quality as Mr. Waters claims they represented, then there was a warranty of quality, and if the skins that were furnished were not equal to the specifications that were made by Mr. Perry and Mr. Skinner, then there is a breach of an express warranty.” It is thus evident that the theory of the complaint as amplified by the bill of particulars, the theory on which the evidence was received and the theory also on which the case was submitted to the jury, was that the plaintiff was entitled to recover upon proof of an express warranty of yield even though it rested exclusively in parol.
We think the judgment cannot be affirmed without disregarding the established rule of law that a written contract merges all prior and contemporaneous negotiations and oral promises relating to the same subject and that when the terms of the agreement are reduced to writing by the parties the written contract is conclusively presumed to integrate their entire engagements. Here the written contracts appear in all respects to be complete, and, being so, must be presumed to have exhausted the intentions of the parties on the subject of these sales. They specify the seller and the buyer, the price, the terms of payment, the quantities to be sold, the dates of shipment and other usual conditions of sale. Among those conditions reference is made to “ this contract ” and across the face of the instrument appears the statement that “ Contracts ” are not binding unless executed by the firm. The plaintiff also recognized this to be so, for after executing the contracts of January 11 and January 14, 1929, it returned them in each instance with a letter in which reference is made to the inclosure as the “ signed contract.” Indeed, the most careful inspection of the written contracts would lead no one to suspect the existence of any stipulation relating to the sales which the parties had not included therein.
But, it is contended, the written contracts here are not complete, because it has been established to the satisfaction of the jury that *125so much of each transaction as constituted the warranty was not included therein and that, therefore, the real contract is provable as existing partly in writing and partly in parol. The answer to this contention is that the contracts appear upon inspection to be in all respects complete and that beyond this our inquiry may not go. (Thomas v. Scutt, 127 N. Y. 133.) We may not have recourse to the parol evidence to ascertain whether they do in fact include the entire agreement of the parties. To do so would nullify the rule, for as the court observed in a leading case (Eighmie v. Taylor, 98 N. Y. 288), “if we may go outside of the instrument to prove that there was a stipulation not contained in it, and so that only part of the contract was put in writing, and then, because of that fact, enforce the oral stipulation, there will be little of value left in the rule itself.” For obvious reasons this does not apply where the writing is manifestly fragmentary. (Routledge v. Worthington Co., 119 N. Y. 592; Thomas v. Nelson, 69 id. 118.) But where the contract is complete upon its face, as it is here, it is conclusively presumed to integrate the final intentions of the parties and may no more be extended by the inclusion of additional terms than it may be contradicted by parol. (Thomas v. Scutt, supra; Lese v. Lamprecht, 196 N. Y. 32; Loomis v. N. Y. C. & H. R. R. R. Co., 203 id. 359; Johnson v. Oppenheim, 55 id. 280; Wilson v. Deen, 74 id. 531.)
Nor can the parol warranty be sustained as collateral on the theory that the plaintiff executed the written contracts in consideration of the separate and independent agreement of the defendants that the sldns delivered would produce a specified quantity of fur. It is very true that a collateral undertaking may, within well-settled limitations, be established by parol. “ Contracts are frequently made that are collateral to, but independent of, a written contract and they can be properly established by oral testimony. Evidence of such contracts is sometimes referred to as an exception to said general rule. It is more accurate to say that collateral and independent contracts can be shown by oral testimony because it was not the intention of the parties thereto to include such contracts in the writing. Collateral contracts are thus frequently established by oral testimony, because they are collateral.” (Lese v. Lamprecht, supra, 36.) An illustration of a collateral agreement, often cited, is Jeffery v. Walton (1 Stark. 267), decided by Lord Ellenborotjgh in 1816. There the parties had executed a written memorandum setting forth a contract for the hiring by the defendant of the plaintiff’s horse. The horse having shied and been injured, the plaintiff was permitted to prove that it was verbally agreed that the defendant would compensate the plaintiff if, in consequence of *126shying, the horse sustained injuries. The court referred to this parol understanding as “ suppletory matter ” by which the parties provided for a special contingency not- covered by the written contract of hire. But before such a collateral stipulation may be shown, the following conditions, stated in Mitchill v. Lath (247 N. Y. 377), must exist: “ (1) the agreement must in form be a collateral one; (2) it must not contradict express or implied provisions of the written contract; (3) it must'be one that parties would not ordinarily be expected to embody in the writing; or put in another way, an inspection of the written contract, read in the light of surrounding circumstances must not indicate that the writing appears ‘ to contain the engagements of the parties, and to define the object and measure the extent of such engagement.’ Or again, it must not be so clearly connected with the principal transaction as to be part and parcel of it.” Assuming all the other conditions to exist, the parol agreement, which is relied on as collateral, does not satisfy the third.
The parol warranty was inseparably connected with the subject-matter of the written contracts. The subject-matter of those contracts was the sale of haresldns.' The warranty was incidental' to the sale. It affected the identity of the merchandise contracted to be sold. It was an element or detail of the principal transaction which contracting parties “ would ordinarily embody in their written contract.” Indeed, it would be difficult to imagine a closer relation than exists between a contract for the sale of merchandise and a warranty of quality. Such a warranty, even if collateral, was so closely related to the sale that it perished when the other terms of the agreement were reduced to writing by the parties. (Eighmie v. Taylor, supra.) To allow it to be established by parol would result in the serious impairment of a rule which experience has shown to be useful and necessary. Chapin v. Dobson (78 N. Y. 74), principally relied on by the respondent, appears also to have been relied on by the trial court. Always regarded as “ near the border line ” (Thomas v. Scutt, supra, 138), it was recently said (Mitchill v. Lath, supra, 383) that it “ is rarely cited except to be distinguished.” It was also plainly intimated (p. 383) that many of the decisions (Morgan v. Griffith, L. R. [6 Exch.] 70; Erskine v. Adeane, L. R. [8 Ch. App.] 756, and Batterman v. Pierce, 3 Hill, 171), strongly relied upon in Chapin v. Dobson, are not in harmony with controlling decisions in this State. Even when approved, it has been only as an illustration of “ the familiar rule that if the writing does not contain on its face the entire agreement between the parties, parol, not inconsistent with its terms, may be received, not to contradict it but to show the real contract. *127But this rule does not apply when it appears from inspection of the instrument that it was intended to express the full and complete intention of the parties.” (Ruppert v. Singhi, 243 N. Y. 156, at p. 160.) If this, indeed, is all that was decided, then Chapin v. Dobson does not concern us here.
It need only be added that many decisions.in other jurisdictions accord with the conclusions which we have expressed. Such is the rule in the United States courts (DeWitt v. Berry, 134 U. S. 306; Seitz v. Brewers’ Refrigerating Co., 141 id. 510), in England (Pickering v. Dowson, 4 Taunt. 779; Chanter v. Hopkins, 4 M. & W. 399), and in other jurisdictions (Glackin v. Bennett, 226 Mass. 316; Telluride Power Co. v. Crane Co., 208 Ill. 218; Storage Co. v. Woods, 99 Mich. 269; Naumberg v. Young, 44 N. J. L. 331; Michigan Pipe Co. v. Sullivan County Water Co., 190 Ind. 14; Miller v. E. L. & P. Co., 133 Mo. 205; Thompson v. Libby, 34 Minn. 374; Case Plow Works v. Niles & Scott Co., 90 Wis. 590; Bullard v. Brewer, 118 Ga. 918; Quinn v. Moss, 45 Neb. 614; Battery Co. v. Railway Co., 138 Iowa, 369; Griffin v. Runnion, 74 W. Va. 641; Ehrsam v. Brown, 64 Kan. 466; Wilcox v. Cate & Bunker, 65 Vt. 478).
The judgment should be reversed and a new trial ordered, with costs to the appellants to abide the event.
