PLEURISY. 



Or inflammation of the lining membrane of the chest 

 and lungs, seldom occurs alone in the ox, for it is nearly 

 always accompanied by pneumonia. Like pneumonia, it 

 is usually caused by cold and damp, but it may result 

 from injury or acute rheumatism. 



Symptoms. — Fever; pulse 60 to 70, small and firm; 

 breathing : inspiration shallow and short, expiration easier 

 and more prolonged, the chest being fixed as it were, the 

 walls of the belly moving more, thus compensating for 

 the shallow motions of the chest walls; sides of chest 

 and rib spaces tender; by placing ear at side the usual 

 respiratory murmur may be heard, and in addition a loud 

 sound, as of leather creaking and rubbing ; dejection and 

 anxiety ; eyes half closed ; head droops ; ears lop ; short, 

 painful, hacking cough ; appetite diminished or lost, &c.

In many cases the inflammation gradually subsides and 

 the animal slowly recovers; but in others water accumu- 

 lates in the chest and ends sooner or later in dropsy.
