Photographs are shown of a book-copying camera using 35-mm. positive motion picture film, and the special features of this camera are discussed. The problem of the reduction ratio is discussed and illustrations shown, with the conclusion that a 10 or 12 to 1 reduction ratio should be employed for book copy work on 35-mm. positive motion picture film. — Photographs are shown of a reading machine of the author's design, and various aspects of the problem are discussed.
