This is an action to recover a balance of about $2,000 due on a promissory note made by Cary, the appellee, to one Andrew Moore, dated June 6, 1893, and payable-November 1, 1894, for $2,500. There was an indorsement of a payment on the note as follows: “June 10, 1893. By credit as per amt. due from statement of per cent, rendered, five hundred and forty-three and 10-100 ($543.10.) [Signed] Andrew Moore. ” The note, after maturity, and for *629a valuable consideration, was assigned to Yocum, the appellant. Simultaneously with the delivery of the aforesaid note to Moore, the following contract of dissolution of partnership was executed (the contract, however, was not mentioned in the pleadings:) ‘‘The State of Texas, County of Grayson. Know all men by these presents, that I, Andrew Moore, of the county and State aforesaid, a member of the firm of Cary & Moore, doing a general merchandise business in the town of Chiekasha, in the Indian Territory, have this day, for and in consideration of the sum of $8,000, to me paid, and to be paid, by J. H. Cary, of Chiekasha, in the Indian Territory, as follows:' $4,500 cash; one note for $500, due November the 1st, 1893; one note for $500, due November the 15th, 1893; and one note for $2,500, due November the 1st, 1894; each of said notes to bear interest from date at .the rate of ten per cent, per annum, to be executed and signed by the said J. EL Cary, and payable to the order of Andrew Moore, at Denison, Texas, — bargained, sold, and conveyed, and delivered, and by these presents do bargain, sell, convey, and deliver, to the said J. H. Cary, all my right, title, and interest in and to the stock of merchandise belonging to Cary & Moore, situated at Chiekasha, in the Indian Territory, and all claims, notes, and accounts due and to become due the said firm of Cary & Moore; the said Cary being authorized to collect any and all claims due the said firm, and the said Cary to assume all indebtedness due by said firm to any and all persons whomsoever; the said firm and partnership heretofore existing between the said Cary & Moore having been by this transaction dissolved, the said Andrew Moore retiring from said firm. Witness my hand this, the 6th day of June, 1893. Andrew Moore. Witness: A. Y. Barnes.” The cash payment of $4,500 and the two $500 notes mentioned in the agreement had, from time to time, been paid; and, as above stated, a payment of $543.10 had been made on the last-mentioned note, of $2,500, leaving due *630and unpaid the sum of $1,956.90 and interest. To recover this balance due on the note, the appellant, brought his action at law in the court below. To this action the appellee, by an amended answer, after admitting the execution of the note, set up the following defense: “The defendant further says that there was no consideration for the execution of said note, and alleges the fact to be that for several months prior to the execution of said note the said Andrew Moore and this I defendant were partners in business under the firm name of Cary & Moore; said Moore having put into said business about the sum of four thousand dollars. That a short time prior to the execution of said note the firm of Cary & Moore had become indebted to various wholesale houses in the sum of about thirty thousand dollars. The assets of said firm consisted of a stock of goods worth from six to eight thousand dollars, and various notes and accounts upon their numerous customers, aggregating about the sum of thirty-six thousand dollars. The creditors of said firm were pressing for the collection of their debts, and in this state of affairs the said Moore informed this defendant that there must be some settlement of said partnership business, so that he (Moore) could retire from said firm, be relieved of its obligations, and withdraw from its assets payment for the money he had put into said business. Thereupon the said Moore and the defendant made of said partnership business as accurate an estimate of its debts and liabilities and assets as was possible at that time to make, and this defendant thereupon assumed said thirty thousand dollars indebtedness, and the said Moore transferred to defendant his interest in said business for the following purposes: The said Cary was to collect the notes and accounts due the said firm, take charge of their merchandise, pay their indebtedness, and pay to the said Moore his part (which was one-half interest) of whatever it should be determined that said firm had earned as profits while engaged in business. An estimate *631was made by the said Moore and defendant of the assets of said firm, and it was believed by them at the time that, after payment of the obligations of said firm, there would be a profit remaining of about five thousand dollars, which' should be the joint property of the said Moore and this defendant. Said note was executed to cover said supposed profits, which could not then be accurately ascertained. There was no other consideration for its execution," and it was executed upon the express condition that it should only cover what should ultimately be determined to be one-half the profits of said firm. Said eight thousand dollars consis téd of notes and accounts which are owing by numerous parties, former customers of said firm, an exact statement of which cannot now be furnished by defendant, but a list of which he is willing to make and file with the papers in this case. Said notes and accounts are owing by parties out of whom nothing can be collected by law, although some of it is owing by parties who defendant believes will pay if they are ever able. For these reasons, defendant says the consideration of said note has wholly failed; and in order to be released of the vexa tion, importunities, and harassments of the said" Moore ani the plaintiff, he here offers to the said Moore and plaintiff one-half of said notes and accounts, and he asks that they be compelled to accept the same, and that defendant be discharged with his costs. Third. Defendant says that, in addition to the credit which appears upon said note sued on, there should be a further credit of five hundred dollars, which was paid on or about the-day of-, 189 — .” A demurrer to the answer was interposed, overruled, and exception duly saved. No motion was made to transfer the case to the equity docket, and the court proceeded to try it at law; calling a jury for that purpose. The defendant, by his answer, having admitted the execution of the note, the court, we think, properly held that the burden of proof was on him, and gave to him the opening and closing ai’guments. Upon *632the trial there were only two witnesses produced, — the defendant, Cary, for himself, and Moore, the payee of the note, for the plaintiff, Yocum. Early in the testimony of defendant, it was developed that the aforesaid contract of dissolution, called a “bill of sale,” had been executed, and was in his possession. He was asked by counsel for plaintiff: ‘ ‘Have you got the bill of sale that Andrew Moore executed and delivered to you? A. Yes, sir. Q. Have y.ou got it with you? A. No, sir. Q. Where is it? A. In my safe. ” The testimony of this witness further developed the fact that this safe was in his house, just across the street from where the trial was being had, and that the paper could have been procured within five minutes. The following objections to the witness’ testimony, and rulings of the court thereon, were then made: “Counsel for Plaintiff: We object to any parol testimony tending to contradict that instrument until the instrument is produced. We object to any testimony on the subject. The Court: I will overrule the objection, but will require them to produce the bill of sale. (To which ruling the plaintiff then and there excepted.) Counsel for Plaintiff: The plaintiff objects to any parol testimony on the part of Mr. J. H. Cary [the defendant] with reference to the transaction he had with Mr. Andrew Moore until the bill of sale about which witness testified, and which was executed and delivered to him, is produced, and counsel for plaintiff have an opportunity to see it; and for the further reason that the testimony offered by defendant is secondary, and no predicate has been laid for its introduction. ” The witness then, over the objection of appellant, was permitted to proceed with his oral testimony relating to the transactions between him and Moore. He admitted the execution of the notes, and the contract of dissolution of the partnership theretofore existing between them, and its delivery to him, and, without producing the instrument of writing, was allowed to testify to the contract *633between them, substantially as set out in his amended answer supra; and this was all the testimony introduced by the defendant. The plaintiff then introduced the contract of dissolution, heretofore set out, and a number of letters which the defendant had written to Moore, tending to prove the contract to have been identical with, and embodied in, the written instrument. The jury found for the defendant. Motion for new trial, motion overruled, exception saved, and judgment for defendant.
There are nine assignments of error. We will notice but three of them, to wit, the sixth, seventh, and eighth, which are as follows: “ (6) The court erred in permitting the defendant, J. H. Cary, over objection of the plaintiff, to testify to a contemporaneous verbal contract between the said parties, for the purpose of contradicting, varying, and changing the effect and meaning of the same; there being no allegation in the pleading of the defendant showing a mistake, accident, or fraud in executing the said contract, and said contract, upon its face, being clear of ambiguity and self-explanatory. (7).The court erred in not peremptorily charging the jury, under the evidence, to return a verdict for ¡he plaintiff for the amount due on the note sued on, for the reason that there was no evidence to support a verdict for ¡he defendant. (8) The court erred in overruling the plain-¡iff’s motion for a new trial for the foregoing reasons, and :or the reason that there was no evidence to support the ver-lict of the jury, and in that the court erred in permitting the lefendant'to prove immaterial facts in support of his alleged evidence, by which he proved a contemporaneous verbal igreement at variance with the terms of the written contact. ”
As to the sixth assignment of error: The pleadings ire silent as to the contract of dissolution. The complaint is i simple declaration on a promissory note, by the indorsee *634thereof. The answer, without divulging the fact that there was a written agreement upon which the note was founded set up that the note was based upon certain partnership transactions between the defendant and Moore, the payee oi the note, and that it had been assigned to the plaintiff aftei maturity, thus letting in all of the equities between th< parties; that the consideration of the note was a one-hal: interest of the profits of the firm which prior to that time hac been made; that these profits consisted exclusively of notes and outstanding accounts, and that one-half of the money t< be collected by the appellee from this source was to consti tute the fund out of which the note was to be paid; that these notes and accounts, presumably without fault of defendant had become worthless; and that, therefore, the consideratioi of the note sued upon had wholly failed. It is contended bj the appellee that this constituted a good equitable defense tc the action on the note, and authorized him to introduce pa rol evidence to sustain it; and he cites as authority in sup port of this contention the case of Burnes vs Scott, 117 U. S 582, 6 Sup. Ct. 865. This is the only authority cited by ap pellee. The facts of this case, so far as the pleadings divulge are very much similar to those of the case cited; and if th< only question were as to the sufficiency of the answer, or a to the admissibility of parol evidence to sustain it, that cas wrould be conclusive of this. Upon the pleadings, they ar< practically the same; but, upon the conceded proof, they ar< entirely different. In the case of Burnes vs. Scott the not' sued upon was the only written evidence of the contract, an< there had been no dissolution of the partnership, or settle ment of its affairs. In this case the partnership had beei dissolved, and a full settlement of its affairs had been made and behind the note there was an instrument of writing executed simultaneously with it, upon which it was based and was a part of the same transaction. This instrumen set out fully the contract between the parties. It providec *635or an immediate dissolution of the partnership. For the lonsideration of $8,000, it conveyed all of the right, title, and nterest in and to the assets, including the notes and accounts, if one of the partners, to the other. It authorized the ap-iellee to collect all claims due the firm, and provided that he hould assume all of its indebtedness. By its terms, in con-ideration of the above, the sum of |8,000 was to be paid as ollows: $4,500 cash; one note of $500, due November 1, 893; one note of $500, due November 15, 1893; and one ote of $2,500, due November 1, 1894, — all bearing interest rom date at the rate of 10 per cent, per annum. Ihe last of the above-mentioned notes is the one sued on in bis case, the others having been paid. Under this instru-íent, which was delivered to the appellee, and accepted by im, and therefore- bound him to the same extent as if he ad signed it, ( Hubbard vs Marshall, 53 Wis. 327, 6 N. W. 97), he took possession of all the assets of the firm, and loore received the cash payment and the notes, and moved ut of the country, into the state of Texas. The contract of issolution and the notes therein mentioned, being part of ae same transaction, and having been simultaneously exe-uted, together constituted the written evidence of the greement. Comparing the agreement, as set out in the written instrument, with the contract set up by appellee’s nswer, and testified to by him at the trial, it will be seen aat they are so widely different that the two cannot stand igether ; that the alleged parol agreement, if allowed to revail, will establish a contract at variance with the terms E the written one. It is admitted by. counsel for appellee, ad is clearly decided in the case of Burnes vs Scott, supra, íat, in a case like this, at law, parol evidence is not ad-.issible to contradict or vary the terms of a written eon-■act. Is it admissible in equity? There is no ambiguity l the written instrument.. It is commendably plain, con-se, and certain. It fully and clearly sets out the whole *636transaction, and fairly and with certainty expresses the coi sideration of the note. As far as it is concerned, it is sel explanatory and needs no interpretation. There is neithi allegation nor proof of fraud in its procurement, or of mi take in any of its provisions. In the admission of parol e' idence to vary the terms of a written contract, equity fo lows the law, and forbids it, except in those cases where is alleged and proven that the instrument was procured 1 fraud, or, by some accident, surprise, or mistake, some pr< vision was included in, or omitted from, the written instri ment, not intended by the parties. Mr. Pomeroy, in h work on Equity Jurisprudence (volume 2, § 806), referrin to the reformation of contracts, says: “ No parol evidenc can be used to modify the terms of a written instrumen and most emphatically where the instrument is required 1 the statute of frauds to be in writing, except upon the o casion of mistake, surprise, or fraud. One or the other < these incidents must be alleged and proven before a reso can be had to parol evidence in such cases. ’ ’ The case i Jones vs Shaw, 67 Mo. 667, is one very similar to this, e cept that in that case the note sued on was the only writte instrument. In that case the answer to the suit against tl maker and indorser of a promissory note alleged that 13 note grew out of certain partnership transactions betwet plaintiff and the defendant, which had proved unsuccessfu that it was indorsed by the other defendant with the unde standing that it was to be paid only in the event that tl partnership turned out prosperously ; that the accounts the concern were still unsettled, and the maker of the nol had paid more than his share of the losses. No othl equitable relief was averred or prayed for. The court hel that the answer did not state a good equitable defense fm either defendant; that parol testimony was inadmissibll under the circumstances, to prove the facts alleged. 1 this case it is not pretended by the appellee that at the tiuB *637f the settlement two distinct and several contracts were itered into, — one written, and the other verbal, — or that íere was a verbal one supplemental to that which was ritten. A contract cannot rest partly in writing and partly l parol; and, where it has been reduced to writing, oral evi-mce of what passed previously, or at the time, cannot be Imitted to contradict or vary it. Here there was an abso-te settlement of a partnership. The assets of the firm ere valued, a balance was struck, the amount due each ember was definitely ascertained, and the retiring member ade a deed conveying to the remaining member all of his terest in the assets of the partnership, iacluding notes id accounts. The remaining member, in writing, by the ,me instrument which evidenced his absolute ownership of e firm assets, agreed to assume all of the partnership in-sbtedness, which indebtedness has been ascertained, and as set forth in the written instrument, and then executed the other his promissory notes for the balance thus found Le. This balance is not only evidenced and acknowledged r the notes, but also by the written agreement executed nultaneously with it. These writings contain no am-guities. They are plain, and their terms are certain. Dthing is left, by them, requiring the interpretation of a urt. Under these circumstances, no fraud, accident, or stake being alleged or proven, parol evidence was not rmissible to vary or contradict them; and, as there are i ambiguities contained in them, no parol evidence was cessary for their explanation. And therefore the trial urt erred in admitting the testimony of- the defendant, er plaintiff’s objection, by which it was sought to change d vary the terms of the written agreement.
Written Instrument. Parol evidence to vary. Contract cannot be partly ■written and partly verbal.As to the seventh assignment of error: This assign-jnt is that the court erred in not peremptorily charging e jury to return a verdict for the plaintiff for the amount e on the note. No such instruction was asked. The *638only evidence offered at the trial for the defendant was hi; own. By his pleadings he had admitted the execution an; indorsement of the note, thus assuming the burden of proof The whole of the testimony related to the contract betweei him and Moore, and was an effort by parol evidence to var; and contradict the written agreement between them, and, a we have above decided, should not have been admitted b; the court. Eliminating, then, this illegal proof, and th case stands, as far as the defendant is concerned, absolutel; without evidence to support it. All of the legal proof hav ing been for the plaintiff, and none for the defendant, th court, of its own motion, should have directed a verdict fo the plaintiff.
Duty of court to direct verdict.As to the eighth assignment of error: This assignmen of error is that the court erred in overruling the plaintiff’ motion for a new trial. For the reasons above given, i was, of course, error in the court to overrule that motion For the errors above set forth, this case is reversed and re manded for a new trial.
