one above described, and constitutes far-sightedness. It is 

 remedied in man by the use of convex glasses. The other 

 remarks made in regard to treatment, etc., of myoj^ia, will 

 also apply to this condition. 



Ossification of the Eyeball. — Cases have been noticed 

 where the eye has become ossified. 



Calcareous Growths, Osseous Deposits, and Melanotic 

 Deposits also are noticed in connection with the eye-

 may also be given with beneficial results. 



Dislocation of the Eyeball. — Dislocation of the eyeball 

 may occur in various ways, and in any animal ; but occurs 

 oftenest in the dog, and usually through fighting. 



Treatment. — If seen at once, there is a possibility of

 and the eyeball is found to be perfectly cold, the circulation 

 having ceased, a cure cannot be made, and there is no 

 recourse but to remove the eyeball.
