PREFACE 



This small volume is the fulfilment of a wish often 

 expressed by the students of the Indiana Veterinary 

 College. It comprises, with the exception of dissections 

 and clinical demonstrations, . the work with the senior 

 class in this department during the term. 



As external diseases of the eye are principally seen 

 in animals, more attention has been given such diseases 

 in as plain and few words as is consistent with the sub- 

 ject, so that they may be comprehended by the student 

 as well as by the practitioner. 



I am indebted to Drs. G. H. Robberts, W. B. Craige, 

 and other members of the Indiana Veterinary College 

 for valuable assistance, and to Drs. G. E. deSchweinitz, 

 Alexander Duane, Wm. C. Posey, and other authors of 

 works on ophthalmology for valuable information. 



As the Hterature upon diseases of the eye in animals 

 is extremely Hmited, I have been obhged to draw 

 largely from 'Taw's Veterinary Medicine," especially 

 on the subject of parasites of the eye.
