The object of this manual is to present to the student who is be-

 the optical defects and diseases of the eye. To this end special 

 attention has been paid to the clinical side of the question ; and the 

 methods of examination, the symptomatology leading to a diagnosis, 

 and the treatment of the various ocular defects have been brought 

 into special prominence. Anatomy, physiology, and pathological 

 histology, except in so far as they serve the purpose just stated, 

 have been omitted. The sections devoted to optical principles and 

 the normal and abnormal refraction of the eye in large portion have 

 betn written by Dr. James Wallace, Chief of the Eye Dispensary of 

 the University Hospital. The chapter devoted to the application 

 of the shadow-test has been prepared by Dr. Edward Jackson. The 

 book will be suitably illustrated by a number of wood-cuts, many of 

 them from cases in the practice of the author, in addition to which 

 there will be several chromo-lithographs.
