The defendant was convicted in the superior court of robbery, and sentenced to the state prison for the term of ten years. Thereafter he moved for a new trial, upon the grounds that the court had erred in its instructions to the jury, that the verdict was contrary to the evidence, and upon newly discovered *460evidence. The motion was denied, and he has appealed to this court.

In support of the first ground, it is urged that the defendant was not sufficiently identified as the person who committed the robbery, and that the evidence showed that at the time of the robbery he was confined to his residence by sickness. There was, however, positive evidence before the jury on the part of several witnesses that the defendant was the individual who committed the offense, and their verdict must be deemed to have determined any conflict of evidence concerning the alibi or as to his identity.

The instructions of the court are not in the record, and we cannot determine whether it committed any error. The failure of the court to instruct upon any proposition deemed essential by the defendant is not to be regarded as error, unless he made a request for such instruction.

Upon the ground of newly discovered evidence it is sufficient to say that the affidavits offered in support thereof were fully contradicted by counter-affidavits on the part of the prosecution, and for that reason the court below exercised a proper discretion in refusing to grant the motion.

The motion to be allowed to file an additional affidavit in support of this ground, after the motion for a new trial had been denied, was properly refused by the court, both for the reason that it had already denied the new trial, and also for the reason that an affidavit of the witness by whom the facts could be shown was not itself produced.

The judgment and order are affirmed.
