If, before the conclusion of a trial, a juror becomes sick, so as to be unable to perform his duty, the court may order him to be discharged. In that case or in the event of the death of a juror a new juror may be sworn, and the trial begin anew, or the jury may be discharged, and a new jury then or afterwards impaneled.
