from Dysenteric Lesions and Other Sources. By W. Glen 
Liston. 
Anyone who lias attempted to study the literature on 
amoebic dysentery and liver abscess must have been struck 
by the confusion existing at present as to the exact differentia- 
tion and life-history of the amoebae, which have been reported 
as the causative agents of this disease. This confusion can 
be accounted for, in large measure, by the inadequate and 
incomplete study of the morphology and development of 
the amoebae which have been supposed to be the causative 
agents. 
Schaudinn (3) first warned us that all amoebae to be found 
in the human intestine were not of the same species. Using 
the method of building up a life-history from the study of the 
changes which are observed in a series of individuals at 
different stages of development — a method which, in his 
hands, had yielded in many instances splendid results — 
Schaudinn showed that there were at least two species of 
amoebae to be found in the human intestine : the one noil- 
pathogenic, which he named Entamoeba coli, the other
