Considering the testimony, the jury found no negligence on the part of the YMCA in the conducting of the beginners’ judo class. Upholding that verdict, the trial court commented: “. . . if the jury had returned a verdict finding the YMCA guilty of negligence, it [the trial court] would have granted a directed verdict. . . .” Reviewing the record, we find no reason to quarrel with either judge or jury. As the jury found, there was credible evidence supporting a no-negligence finding. As the judge commented, it is difficult to find any evidence that would support a different conclusion.

Defendant’s request for double costs, based on incompleteness of appellant’s brief and appendix, is denied. Since double costs are a discretionary penalty, we elect not to have the plaintiff thrown for this additional loss.

By the Court. — Judgment affirmed, with costs.
