General Management in Disease 



no value, yet it may continue to perform its work 

 fairly well. The cough may be disguised by an 

 unprincipled vendor through the administration 

 of such substances as shot and grease ; but this is 

 only temporary, and, of course, the abnormal 

 breathing cannot be disguised. In some cases 

 of broken wind, the air-vesicles of the lungs have 

 been found, after death, ruptured; and the walls 

 of the stomach dilated, though this is not constant.

Bronchitis 



Inflammation of the bronchial tubes is frequent 

 amongst all classes of animals, and sometimes exists 

 simply as Bronchitis, but much more frequently in 

 combination with other diseases of the lung, such 

 as, tuberculosis ; glanders ; catarrhal pneumonia, 

 etc. The large or the small tubes may be involved, 

 and as long as the inflammation remains confined 

 to the larger bronchial tubes, there is not much 

 danger; but when the capillary tubes are implicated 

 there is the risk of catarrhal pneumonia developing. 

 Atmospherical ; chemical ; mechanical ; and specific 

 cause, are the chief agents operative in the pro- 

 duction of bronchitis. The bronchitic rale is 

 pathognomonic of the malady, and is due to the 

 passage of air through the liquid in the tubes.
