PHRENITIS, OR INFLAMMATION OF THE 



BRAIN. 



The term staggers used to be applied to this disease, 

 but it is only a symptom of this and otlier diseases. 

 Phrenitis is produced by a determination of the blood to 

 the brain. 



Causes. Change from poor to high feeding and rich 

 pastures, over-exertion in close, sultry weather, espe 

 cially in fat, high-fed horses, lately accustomed to only 

 a little labor. It sometimes resuhs from other diseases, 

 or a change of inflammation from one organ to another , 

 it may suddenly leave the bowels, lungs, or other parts, 

 and attack the brain. But it is usually caused by a 

 diminution of the excretions which produce costiveness 

 and induration of the contents of the intestine, and a 

 strong flow of blood to the head. 



Symptoms. Hanging of the head, dulness, watery 

 eyes, reeling of the body, and sleepiness. While eating, 

 the animal becomes lethargic, droops his head, with the 

 tongue hanging out and saliva dribbling ; and he will 

 stagger and almost fall. If aroused, he stares around, 

 ancl "then slumbers again. If he falls, he will start up 

 as though frightened, wander about, stagger and fall 

 again.
