324 OCTOBER TERM, 1907. �Opinion of the Court. 209 U. ? being opened, to have been intended for the complainer. The letters that ?re addreded to the defendant by its corpo- rate name cannot be known to have been intended for the complainant until they have been opened. In other words, there is notbAng on the outside of the letters from which it could be determined that they were not intended for the com- pany to which they were addressed by its corporate name, but for the complainant. Some of the letters thus addreded have been, in fact, intended for the defendant company, although a very small proportion of them.
