 man, are inflamed and ulcerated in different 

 degrees. 



The mucous membrane of the large intestine

 we often meet with ulcerations which are 

 smaller in the upper part, larger and deeper 

 about the lower or rectal part. The mem-

 or the functional derangements. In two 

 cases in which disorders of the respiration 

 had prevailed, and which had been sacrificed 

 on the eighth or tenth day of the disease,
