sion of this nerve at the back of the eye, on which the impres- 

 sion of objects falls. It may be the consequence of staggers, 

 apoplexy, or be produced by tumors pressing on the nerve, 

 etc. It'may be sympathetic, resulting from disease of other 

 oro-ans, as indigestion or debility. _ 



Treatment— Some authors make a general sweep on this 

 point, and pronounce gutta serena incurable. And though 

 our own experience has not been extensive in this disease, we 

 see no reason why it might not be as curable as the same dis- 

 ease in the human patient, or nearly so, at least. There are, 

 however, well-authenticated cases of cure; but they have, 

 doubtless, been such as were the result of mere functional de- 

 rano-ement of the optic nerve, resulting from other diseases 

 or debility; being only symptomatic, and not connected with 

 positive disease of the nerve, nor the consequence of disease 

 of the brain. These cases may certainly be regarded as in- 

 curable If any thing could be done, it would be by setons 

 under the jaw, and, twice a day, passing a current of electro- 

 magnetism along the course of the nerve; placing one pole of 

 the battery by the eye, below it, and the other at the butt of 



the opposite ear. 



If the horse is in high condition, his feed should be reduced 

 somewhat, and a physic given once or twice a week.

The head should be frequently sponged with cold water. 

 But if the case is one of debility, rather an opposite course 

 will be required. Tonics (strengthening medicines) and al- 

 teratives (such as act generally, improving the system) will 

 be proper.
