Give the morbid anatomy of enteritis. 



The mucous membrane alone may not only be involved, but it 

 may extend to the muscular coat, thus preventing the forcing of 

 the food along the intestines, which become paralyzed or partially 

 so. On post mortem signs of peritonitis are most always present. 



The mucous membrane is reddened in patches, as a rule, thick- 

 ened, softened, and often ulcerated. 



This is not a very common disease, and it takes some time for

What is the aetiology ?

What are the symptoms ? 



This is a febrile disease, the temperature during the congestive 

 stage may rise to 104° or 105° F., but as soon as the exudation 

 is thrown out it reduces and varies from 103° to 103|° F., and 

 sta3's about this way until death approaches, when the temperature 

 again rises. 



The -pulse in enteritis is small, weak, and compressible, and 

 very rapid. 



The respirations are accelerated and thoracic. 



The mucous membranes are highly injected, the mouth is
