Lake, Ch. J.
I. The action in the court below was brought by the plaintiffs, as indorsers of two promissory notes executed by the defendant, for $167.50 each, negotiable and payable in twelve and eighteen months respectively. By the bill of exceptions it appears, that the plaintiffs received said notes in the,ordinary course of business before maturity, paying therefor a valuable consideration, so that they are to be regarded in the light of innocent holders of commercial paper. The defense, which seems to have been relied upon on the trial, and in respect to which the alleged errors occurred, consisted of an alteration of these notes by, the payee, before they were transferred to the plaintiffs. This alteration was effected by detaching from each of the notes the words, “this note is given upon condition,” which had been appended thereto by the maker, after he had signed them, but before their delivery to the payee.
Of themselves, these words were wholly ineffectual to vary or modify the terms of the notes to which they were attached, even as between the maker and payee. *225What the nature of the condition was, or whether it had the effect, in a certain contingency, to change the liability of the maker, nowhere appears. Surely it cannot be legitimately inferred from them, that the payment of the notes was made conditional upon the happening of any event whatever; nor do we see how the removal of these words could have prejudiced the defendant in the least possible degree. It is doubtless the law, as adjudged in numerous eases, that a memorandum wi'itten under a promissory note, and qualifying it, is to be taken as a part of the contract, and given due weight in its construction. So, too, the fraudulent removal of such a memorandum vitiates the note, and avoids the obligation of the maker, even in the hands of a bona fide holder. Wait v.

Benedict v. Cowden, 49 N.Y., 396" court="NY" date_filed="1872-05-21" href="https://app.midpage.ai/document/benedict-v--cowden-3605195?utm_source=webapp" opinion_id="3605195">49 N. Y., 396 (10 Am. Reports, 382). These were cases where the alteration was of a material part of the contract, by which the liability of the maker was altogether different from that which he originally assumed. But in the case before us, for aught that appears, the alteration was of an immaterial part, and furnishes us no ground whatever to defeat a recovery on the notes.
We hold, that, when the plaintiffs had established the fact of their being bona fide holders of these notes, for value, they were entitled to a verdict in their favor, notwithstanding the alleged alteration. It follows, therefore, that the testimony of the two witnesses, Riggs and McPherson, as to the alteration, and to which the plaintiffs objected, on the ground of its immateriality, should have been excluded from the jury. Its admission gave the jury to understand that it was material to the issue, and proper to defeat a recovery on the notes. In this, we think, there was error, which calls for a reversal of the judgment.
*226II. The court was requested, on behalf of the plaintiffs, to charge the jury, that, if they found from the evidence, “ that the plaintiffs were bona fide holders of the notes, and received them in good faith, indorsed to them by L. S. Riggs, the payee, before due, and for a valid consideration paid by them, the jury should find for the plaintiffs.” This was refused, and the following instruction substituted and given, viz: “ If the jury find from the evidence, that the plaintiffs are bona fide holders of the notes in controversy, and received them in good faith, properly indorsed before due, and for a valuable consideration, and that said notes have not been materially changed, then, in that event, you must find for the plaintiffs.” The first of these instructions was based upon the idea, that the alleged alterations of these notes was entirely immaterial, furnishing no reason whatever why their payment should not be coerced. In it we think the law of the case was stated correctly, and it ought to have been given as requested, and without modification.
In the instruction which the court substituted for this one, there is error in the portion which we have italicised, by which the jury were intrusted with the duty of deciding upon the materiality of the alteration. This duty rests upon the judge presiding at the trial, and could not be shifted upon the jury. Further, we are of opinion, that the instruction given by the court, on its own motion, was well calculated to mislead the jury, for while abstractly considered, it states the law respecting the alteration of commercial paper correctly, it was inapplicable to the case as made both by the pleadings and the evidence. The jury were given to understand, by the silence of the court on that point, that the alleged alteration, if established, was fatal to the plaintiffs’ case. They should have been told that it was of no conse*227quence whatever, and could not relieve the defendant of the obligation which he had assumed.
For these reasons the judgment of the court below is reversed, anda new trial awarded.
Judgment accordingly.
