¶1This was an action for divorce, tried before a jury, without settling issues. There were two questions submitted: one as to the adultery of the defendant; the other as to its con-donation if committed. The verdict was a general one of no cause of action; and we are left to the record to determine why such a result was reached by the jury. A careful reading of it convinces us that the proof of adultery was sufficient to require a verdict in favor of the plaintiff, and, consequently, the jury probably were of the opinion that the offense had been committed and forgiven.
¶2We think that the defendant failed to establish condonation by a fair preponderance of evidence. The plaintiff should have such knowledge as would justify a reasonable person in con-*860eluding that the fact existed; a mere hysterical jealousy, where the fact is denied by the alleged guilty party, is not sufficient. (Deisler v. Deisler, 59 App. Div. 207; Harris v. Harris, 83 id. 123, 127, and authorities there cited.)
¶3The judgment and order should be reversed and a new trial granted.
¶4All concurred.
¶5Judgment and order reversed, on the ground that the verdict on the question of condonation is against the weight of the evidence, and new trial granted, with costs to the appellant to abide the event.
