If the verdict should be so defective that the court should be unable to determine the intention of the jury to acquit or convict the defendant of the offense under which the defendant might be convicted pursuant to the information, or be unable to determine of what count or counts the jury wished to acquit or convict the defendant, the court may charge the jury to reconsider said verdict and state plainly their intention. But if the jury persists in returning an informal verdict, said verdict shall be accepted and the court must give judgment of acquittal.
