delivered the opinion of the court.

We have felt no hesitation upon the point discussed in this case concez’ning the constructiozi of our statute. An admissiozi that the absent witness would swear to the facts disclosed in the affidavit for a continuance, is not such azi admission as is required by the ninth section of the tenth article of our practice act. To authorize the court to compel a party to go on with his case in the absence of his witness, the opposite party must admit the truth of the facts proposed to be proved by the absent witness, and not merely that he will swear to them. This, it is true, gives the party an advantage on this point, which he would not have if his witness was present; but as he has a strict right to a continuance' under the general provision ozi this subject, it was perhaps not thought just to deprive him of this right without such a concession from his adversary as would plainly take from him all cause of complaint. Besides, this is the plain letter of the law, hardly admitting of any other than a literal construction.

The principal difficulty in this case arises out of the course pursued by the defendant upon his application for a contiziuance being ovez’ruled. He abandoned the case, taking no bill of exceptions giving a history of the trial which took place subsequent to this ruling of the court.

There are undoubtedly errors committed in the progress of a cause, which may not be fatal to the judgment, by reason *324of anterior, attendant or subsequent circumstances disclosed by the bill of exceptions. An erroneous instruction may turn out to be harmless, or an improperly excluded, deposition may appear to be irrelevant, and the history of a trial may show that errors have not been prejudicial to the party complaining. In such cases, the court does not necessarily reverse the judgment. A deposition may be excluded by the court that tries a case for want of proper authentication, and this court may be of opinion that the authentication is good, yet if the deposition itself is not preserved, so that it can be seen whether it relates to any matter material to the issue, this court does not notice the error. But, in this case, the application for a continuance was supported by the requisite affidavit, and the testimony proposed was competent. What influence the excluded testimony would have had upon the verdict, it is not for us to conjecture. It is sufficient that the testimony was competent and relevant, and that this competency and relevancy are shown by a bill of exceptions preserving the proffered evidence, and that the party was not allowed an opportunity of producing it. Of what avail, then, would the history of the subsequent trial be ? or what subsequent circumstances could have rendered this evidence incomplete ? It might be cumulative, or it might turn out to be upon a point upon which the case ultimately did not turn, but this does not authorize a court to exclude evidence.

Whilst, therefore, we think the practice of abandoning a case, upon a single exception, to be a dangerous experiment to the party relying on such error alone for a reversal, yet we have, with some hesitation, concluded it most in conformity to the established practice of this court, to reverse this judgment for the error in refusing a continuance, notwithstanding the failure of the party to take a bill of exceptions detailing the subsequent course of the trial.

Judgment reversed and cause remanded;
