In all trials for criminal offenses, the jury, after having received the instruction of the court, shall have the right, in their verdict of guilty or not guilty, to determine the law and the facts of the case, but it shall be the duty of the court to superintend the course of the trials, to decide upon the admission and rejection of evidence, and upon all questions of law raised during the trials, and upon all collateral and incidental proceedings; and also to allow bills of exceptions. And the court may grant a new trial in case of conviction.
