 Price 2/6. 



We consider the title of this book somewhat misleading, and are therefore 

 disappointed with it, as it is almost exclusively confined to a description of the 

 eye and spectacles. The author says his object " has been to place before the 

 reader a descriptive outline of a few of what may be safely termed the more 

 popular instruments in use. Taking the human eye as the most important, 

 most instructive, and certainly the most valuable optical instrument known to 

 science, its construction and properties are first of all dealt with."

The present volume is a thoroughly up-to-date one, and one which must 

 prove of great help to the photographer. The subject-matter is carefully 

 arranged in sections, Sec. i being Tables of Reference and other useful infor- 

 mation for Photographers, Photographic Dealers and Dark Rooms, Photogra- 

 phic Trade-marks of 1895 ' Sec. 2, Selected Articles on Practical Subjects by 

 Practical Men ; Sec. 3, Annals of Photography, being a Record of Progress in 

 the several branches of the Science and Practice of Photography during 1895, 

 including Photo-Chemistry, Photo-Optics, Photo-mechanical Printing, Photo- 

 graphic Art and Rontgen Rays, and Astronomical Photography ; Sec. 4, The 

 Photographic Societies of the United Kingdom ; Sec. 5, The Latest Novelties 

 in Photographic Apparatus and Materials, forming a continuation of the infor- 

 mation contained in the Photographer's Indispensable Handbook and Photo- 

 grapher's Annuals, 1892-3-4, and 5 ; Sec. 6, The Latest Novelties in Optical 

 Lanterns and Appliances relating thereto, forming a continuation of the Infor- 

 mation contained in the Indispensable Handbook to the Optical Lantern and 

 Photo Annuals for the years 1S91-2-3-4, and 5 ; Sec. 7, Description to the 

 Illustrations and Directories to the Photographic Trade. There are between 

 300 and 400 illustrations in the text, and a number of beautifully executed 

 photo-mechanical full-page plates. We think the volume far in advance of 

 any of its predecessors.
