-It is first assigned for error, that the court had no right to refer the assessment of damages to the cleric, and that there was no sufficient verdict upon which a judgment could be rendered. But can defendant take advantage of this, at this time? We think not. If the form of the verdict was defective, it .might have been cerrected at the time of its rendition, had the defendant objected, and thus have obviated the necessity of referring the assessment to the clerk. We think the objection must have been taken in the court below, to avail the party in the appellate court. Schleneker v. Risley, 3 Scam. 488; Bank of Illinois v. Batty, 4 Ib. 200.
Aside from this, however, we think the court committed no error in directing the assessment and rendering the judgment for the amount. The action was upon a note, clear and definite as to the date, maturity, and interest. The only issue was the execution or non-execution of the note. To this issue, the jury, by the verdict, did respond. The party in whose favor they fouijd, is also distinctly stated. And they also do, for all practical purjeoses, assess the damages. There is no difficulty in arriving at absolute certainty, from such a verdict. The mind can have no hesitation in saying, that the intention of the jury is expressed, and so expressed, that but one judgment could be rendered, and that for an amount definitely ascertained from data which had been found by the jury. The form is sufficient, if it expresses the intention of the jury. Code, § 1720. We do not then treat the assessment as made by the clerk, but by the jury. The verdict might have been more formal, but could scarcely be more certain. Had the pleadings been otherwise; had there been other and different issues, or the cause of action other than a promissory note, there might be more room for doubt. In this case, however, there is no pretence that the judgment was for anything beyond the amount of the note and interest, which was what the jury found and reported, in legal effect; and for such want of form, we would not *33disturb the case, even if objection had been made at the proper time. Upon this subject, see Beckwith v. Carleton, 14 Geo. 691; James v. Wilson, 7 Texas, 230; Wells v. Barnett, Ib. 584; Smith v. Johnson, 8 Texas, 418; Findley v. Buchanan, 1 Blackf. 12; Heddy v. Fullen, Ib. 51.
It is next urged, that the court erred in giving the instruction asked by plaintiff, and this presents-a question of more difficulty. The appellant claims that it was erroneous, because there was no evidence to justify the court in giving ■such instruction; that the evidence shows, that the experts who testified, had a personal knowledge of the handwriting, and swore as well from such knowledge, as from mere comparison ; and that, therefore, the instruction, if correct, was predicated upon an improper basis, and was calculated to mislead and confuse the jury. The appellees, on the other hand, admit that the instruction had no application under the proof made, but that the jury could not have been misled by it, and therefore, if erroneous, which is denied, it -cannot operate to reverse the case.
It may be regarded as settled, that the giving or refusing an instruction, upon a mere abstract proposition of law, which does not refer in any way to the evidence in the case, or issues made, would not be such an error, as will warrant a reversal, unless it may be fairly -inferred, that the jury was thereby misled to the prejudice of the party complaining. If it was erroneous, but could have had no effect upon the finding, it would be no ground for error in this court. It is also true, that the instructions should apply to the facts proved, but if they have no such application, and could have ho influence on the verdict, though erroneous, they will afford no ground for a reversal of the j udgment. Horner et al. v. Wood et al., 16 Barb. 386; Atkinson v. Lester, 1 Scam. 407; United States v. Wright, 1 McLean, 509; Smith v. Carr, 16 Conn. 450; Cummings v. Chandler, 26 Maine, 453. The giving of an instruction, involving a mere abstract, legal proposition, may not aid the jury, nor does it necessarily follow that it had an improper influence. But if erroneous, ' *34and it appears that it could have had an influence prejudicial to the interests of the excepting party, this court will be justified in reversing it. Corbin v. Shearer, 3 Gilm. 482; Carson v. Lucore, 1 G. Greene, 33. And in the case of Benham v. Cary, 11 Wend. 83, it was held,” that where the charge of the court had a tendency to make an erroneous impression upon a jury, and mislead them in their views of the case, a new trial should be granted.
In view of these general propositions, let us examine the question presented. It is very evident, that the instruction, given, was not applicable to- the facts proved. The witnesses gave their opinion, as experts, from their lenowledge of the handwriting of defendant, and not from a mere comparison of writings or signattíres, of which they had previously known nothing. That such testimony is entitled to more weight, than if the witness had spoken alone from comparison, is recognized by the instruction, and must be admitted. If it be true,' then, that the evidence of experts, unacquainted with the signature, is the lowest and least satisfactory kind of evidence, as to the genuineness of the disputed signature, it is fairly inferable, that the giving of such instruction would mislead the jury, under the circumstances disclosed. And we conclude, that it would have such an influence. Here was a controversy as to the genuineness of a signature to a promissory note. The record shows, that witnesses were introduced,, part of whom testified, that from, their knowledge of defendant’s handwriting, they'believed it to be genuine. Others, again, from a like knowledge, were of the opinion that it was not his signature. Some of these latter witnesses were experts,, and the genuine handwriting being shown them, they gave their opinions, as such experts, from their knowledge of defendant’s handwriting. On this proof, the jury are informed, that the evidence of experts, who are not acquainted with the handwriting, is the lowest and least satisfactory kind of evidence. Now, we certainly hazard nothing in saying, that jurors, upon a question which has elicited conflicting opinions*.' from the highest tribunals, might well be misled by such an *35instruction, and must almost necessarily, have treated the testimony actually given, of the lowest kind. If so, the defendant must as necessarily have been prejudiced.
We conclude, then, that the instruction was inapplicable, was calculated to mislead the jury and prejudice defendant’s interests, and should, therefore, have been refused.
It, therefore, becomes unnecessary to inquire into the correctness of the instruction given, under a state of case, where the question might properly arise.
Judgment reversed.
