When the jury have agreed upon their verdict, they must be conducted into court, their names called by the clerk, and the verdict rendered by the foreman. When the verdict is announced, either party may require the jury to be polled, which is done by the clerk asking each juror if it is his verdict. If any one answer in the negative, the jury must again be sent out for further deliberation.
