Pleurisy. 



This disease consists of an inflammation of the 

 delicate membrane which lines the chest, and also is 

 reflected over or covers the lungs. 



It is caused most frequently by exposure to cold, 

 or from the extension of catarrh. Pleurisy rarely 

 exists alone, but is almost invariably complicated 

 with bronchitis or pneumonia, or both. 



SYMPTOMS, The disease generally begins in the 

 same manner as pneumonia, with dullness, loss of 

 appetite, etc. The cough is attended with pain, and 

 seems to be cut short as if the animal tried to stop 

 it; the breathing is short, seemingly cut off and 

 evidently painful during the passage of the air into 

 the lungs, and is attended with a grunt during its 

 expiration ; the sides are painful when pressed upon ; 

 the skin, at the angles of the mouth, is wrinkled ; 

 the shoulders and upper part of the chest are in a 

 constant quiver ; the head is stretched out ; the eyes 

 are unusually bright ; the tongue hangs out of the 

 mouth, from which frothy slaver is continually flow- 

 ing. The animal neither eats nor chews the cud ; 

 she gets weaker and thinner every day, and all the 

 symptoms become more and more severe until death 

 ensues, often preceded by excessive purging.
