 tion, a septic state, and death. This sort of extension 

 has been more common in the writer's experience than 

 others, even to the liver. 



The disease of the intestine may be divided into 

 an acute and a chronic stage, the latter by far the 

 more common, the former the typical condition of 

 amoebic dysentery. 



It is convenient and permissible, both from the 

 pathologic state and the clinical aspects, to divide 

 intestinal amoebiasis into two phases, chronic in- 

 testinal amoebiasis and amoebic dysentery or acute 

 amoebic colitis. 



CHRONIC INTESTINAL AMOEBIASIS 



This is the most common phase of the disease and 

 covers, in our present knowledge, the carrier states. 

 During its course or as its termination may occur a 

 flare into the acute state of amoebic dysentery. Dur- 

 ing its course may also occur liver abscess, or rare 

 accidental metastases elsewhere. 



The clinical state is confused and not subject to 

 a positive diagnosis without finding the amoeba. 



Those of wide experience with the disease, notably
