The Chief Justice delivered the opinion of the court.

It was insisted by the counsel for the plaintiffs, that the discrepancies between the declaration and the proof, were nothing more than mere clerical errors, or misprisions, and amendable, as a matter of course; that they ought therefore to have been considered as amended, at the circuit; or at least in furtherance of justice, the Judge ought to have taken the verdict, leaving the party to move for an amendment on the coming in of the postea.

*53But I think the Chief Justice did right in non-suiting the plaintiffs. These were not clerical mistakes, appearing to be such, on the face of the record. The record was not incongruous : it was perfect in itself, and might have been true, but it was not supported by the evidence. The plaintiffs were not non-suited for a mistake, either of the pleader, or his clerk; but for a variance between the declaration and the proofs. I do not see by what authority, the Judge could either amend, or consider as amended at the circuit, a matter of this kind. Suppose the action had been on a special agreement, resting in parol, and on the trial, the agreement sworn to by the witness, was in one or more particulars, fatally variant from the one set out in the declaration — would it do, upon the ground of mistake in the draftsman of the declaration, in relation to what his client or the witness told him of the particulars of the agreement, to consider the declaration as amended or rather altered so as to meet the proof ? — or woidd it do to go on with the trial upon the presumption that the court at bar, will give leave to amend after verdict? I should think not. And yet that may be as pure a matter of mistake in the pleader, as the misrecital of a statute, or the misnomer of a commissioner. Such a course would be, to try a cause upon one issue, and give judgment upon another.

It is unnecessary, however, to pursue this subject, after what was said by the late Chief Justice, who delivered the opinion of the whole court, in the case of Den v. Hull, 4 Halst. R. 277, and in which I entirely concur. But although the Judge has no power to order amendments at the circuit, it does not follow that he ought to non-suit the plaintiff, for every variance between the record, and the proofs or documents given in evidence on the trial. A more slip of the pen; a mistake of a clerk in copying, and which appears on the face of the record itself to be a mistake, such as a wrong name or date, where the true name or date appears on other parts of the record, ought to be overlooked at the trial, and the party be permitted to apply at bar, for leave to amend by the writ, or the pleadings on file. Sayer v. Pocock, Cowper, 407; Grundy v. Mell, 4 Bos. and Pul. 28 ; 2 Archb. Pr. 239 ; Shepley v. Marsh, 2 Str. 1131; Leeman v. Allen, 2 Wils. 160, are cases illustrating my mean*54ing in this respect. But the case before us, is not one of that kind. Here is no variance between the issue roll or pleadings on file, and the nisi prius record. The mistake or error is in the original declaration, and the non-suit was therefore properly granted. That being the case, can the court set it aside— reinstate the plaintiffs in court, and give them leave to amend? It was so done by this court, in the case of Den v. Hull, 4 Halst. 277, already cited; and in the case of Den v. Franklin et al. 2 South. 851, the same thing was done, in effect. I do not consider these decisions, however, as establishing the broad principle that in every case, after the plaintiff has been properly non-suited at the circuit, he may have the non-suit set aside, and be permitted to amend, or alter his declaration, and have a second trial. On the contrary, when the plaintiff has failed to make out his case, for want of sufficient proof, whether that result was owing to his negligence, or a real inability to prove his case as laid, I think the non-suit, or verdict, if one has passed for the defendant, ought not to be set aside, to give the plaintiff a second chance. This would be to suffer a party to try experiments, and speculate upon the opinion of the court, and the evidence in the cause. ■ But where, as in the case of Den v. Hull, there has manifestly been a mistake in preparing the circuit record, or where as in the present case, an error has occurred in the pleadings, by inserting a wrong name or date, it would be a reproach to the administration of justice, to turn a party out of court, and drive him to a new action. Upon the authority of the case of Den v. Hull in this court, and the cases there cited, and of others that might be enumerated, I am of opinion, that the non-suit should be set aside, and the plaintiffs have liberty to amend, in the manner specified by them, on payment of costs of the circuit; and in case the defendants shall amend or alter their plea, after the declaration has been amended, then, on payment of costs of putting in the original pleas.

Ford and Ryersost, Justices, concurred.
