Amoebae 
I would also acknowledge my indebtedness to Major W. G. Liston, 
who very kindly gave me much helpful advice by correspondence, acting 
upon which I have undertaken the differentiation of the two types of 
amoebae and have put the subject in its present form. 
I should like, finally, to record my appreciation of the very ready 
help given me by Sub-Assistant Surgeon, Jugesh Chandra Guha in 
these observations.
