malarial parasites with that of Coccidia, and introduced 

 a terminology which is in use up till now. Nuttall (1901) 

 gave a useful summary of the researches on malaria, recording 

 the various works in a chronological order, and the interested 

 reader may be referred to it for fuller details. Laveran (1907) 

 also reviewed the pubhshed literature.

Schizogony takes place in the red blood-corpuscles, usually 

 in the internal organs, but rarely in the peripheral blood. 

 The fully developed schizont may more or less displace the 

 nucleus of the host-cell or not affect it at all. Gametocytes 

 spherical, ovoid or vermiform, in some species closely re- 

 sembling those of Laverania. Sporogony as in the human
