This book contains ten chapters as follows: 1, Historical Sketch; 2, Physiological Anatomy of the Retina; 3, Physics of Light-color Sensations; 4, Theories of Color Perception; 5, Color Blindness; 6, Methods for Detecting Color Blindness; 7, Pseudo-isochromatic Tests, Contrast Tests, Special Tests; 8, Acquired Color Blindness; 9, Pennsylvania Railway Company's Instructions; 10, Oliver's Tests, and General Remarks.
The book applies exclusively to railway employés, but it does not touch upon the subject of its enforcement by the Treasury Department of the Government, nor are the statistics of the Public Service, although easily accessible, touched upon. So far as its scope extends, the book is an excellent one and will be of use to all railway surgeons.
