 Illustrated, pp. 96. (Rochester, N.Y., U.S.A. : Bausch and Lomb Optical

The author tells us that he has started out in this little manual with the 

 supposition that the purchaser or owner is a beginner, and absolutely ignorant

 attemped to convey, step by step, and in simple language, information which 

 will lead to ease of manipulation and pleasure in its use- \Vc think he has 

 succeeded.
