      Abstract of the Decision.
    1. Evidence, § 304
      
       — when exclusion of letter is error. Where a defendant partner, called and examined by the plaintiff under Municipal Court Act, sec. 33 (J. & A. If 3345), identifies a letter signed by the firm and written by their bookkeeper and testifies that he told the bookkeeper to write the letter, it is error to exclude the letter on the ground that the bookkeeper’s authority to sign it was not shown.
    2. Appeal and erbob, § 1772* — when admission of evidence in trial by court is ground for reversal. Even though a cause is tried by the court without a jury, and it will be presumed that the court did not consider incompetent evidence which it allowed to be in troduced, the admission of such evidence when accompanied by a restriction upon the introduction of competent evidence by the other party may be a ground for reversal.
