altered state of the evacuations, and the general derangement 
of the secretions. 
A more detailed examination of the subject will necessitate 
a classification of the malady under the heads of acute, sub¬

Acute diarrhoea most commonly occurs in the horse: its 
appearance is usually sudden, its progress rapid, and its 
termination often fatal. The causes which are concerned in 
its production are various : exposure to cold and wet may be 
estimated as among the most frequent. 
The influence of cold upon the surface of the body is a 
cause of many internal derangements, not merely from the 
interruption to the circulation in the cutaneous vessels, but 
probably even more decidedly from the impression upon the 
nerves. A rapid transition of the sensation of cold is experi¬
