panied by cough, rough coat and tight, harsh skin. Rough or loud 
respiratory sounds are sus- 
picious, and, in advanced cases, 
it is often found that the ani- 
mal groans when pressure is 
brought to bear upon the 
chest wall. Many cases bloat 
habitually due to presence of 
enlarged glands upon the eso-

lymph glands are suspicious 
but there are other causes for 
enlargement of these glands. 
In tuberculosis of the lungs,
