another " new species " called " E. brasiliensis." They were seen later 

 by Ujihara (1914) in Formosa, and correctly referred to E. histolytica. 

 Ujihara* apparently studied five different strains of E. histolytica, with 

 cysts of the following mean diameters approximately : 68 /i (i case), 

 8"5 /<• (3 cases), 10*24 yu, (3 cases), 11-95/* (7 cases), 156/1 (4 cases) 

 Unfortunately the author does not state how many cysts he measured 

 from each case, nor how he made his measurements. It is impossible 

 to know what exact value to attach to his figures in consequence.
