flamed, but the button-like ulcers on the lining membrane of 
the intestines and stomach, which are characteristic of cholera, 
are absent. The lining membrane of the stomach and intestines 
is commonly inflamed, and sometimes ulcers are present, but 
the ulcers differ from those of cholera, being more hollowed 
out and less button-like in appearance.

Pneumonia is more serious than bronchitis and frequently 
causes death in a very short time. It often results from a
