APPENDIX. 



The following are some of the diseases that have been 

 reported to this department as occurring in different parts 

 of this State : 



"Pink-Eye" has been reported as occurring among horses, 

 mules and cattle. A large number of the cases of so-called 

 "Pink-Eye," among horses and mules, was due to inflamma- 

 tion of the conjunctiva and sometimes of the cornea, asso- 

 ciated with influenza, cold in the head, or strangles (distem- 

 .per). An inflammation of the mucous membrane of the 

 nasal passages may extend to the mucous membrane (the 

 conjunctiva) of the eye by way of the tear canal and the 

 tear ducts ; or, some of the mucous discharge from the nos- 

 tril may accidentally get into the eye. A few cases of "Pink- 

 Eye" among cattle were associated with malignant catarrh ; 

 while nearly all "Pink Eye" cases among cattle have been 

 outbreaks of infectious conjunctivitis and keratitis. 



"Hooks" have been reported, in a number of instances, as 

 a prolific cause of blindness. One man spoke of "bone 

 hooks" and "fat hooks," but failed to explain the technical 

 meaning of these terms. However, the indiscriminate prac- 

 tice of cutting out the haw or "eye washer" when the eye is 

 affected with conjunctivitis, moon blindness, or tetanus 

 (lockjaw) is certainly useless, if not barbarous.
