 GOTTFBIED V. MILLER. 471 �United States. In those courts the extent of the rule is to permit the jury to compare writings lawfully in evidence for some other purpose. It has never been permitted to introduce writings for the mare pur- pose of enabling the jury to institute a comparison of writings.
