Ῥ. falcip’arum quotidia’num, the rasite of quotidian estivo-autumnal fever. Ῥ. plas’tokon, Schiller’s supposed protozoan parasite of cancer. Ῥ. mala’riw, the hematozoén of malaria: a parasite existing in various forms in the red blood-corpuscles in malaria, and originally developed in the body of mosquitos of the genus Anopheles, being transmitted to man by the bite of such mosquitos. Three species are recognized: P. vi’tax, the tertian parasite; P. malu’ria, the quartan parasite; and P. immacula’- tum or falcip’arum, the parasite of pernicious or tropical malaria. The parasite is an irregular ma of protoplasm exhibiting ameboid movements, and increasing in size until it fills the entire corpuscle, at the same time becoming pigmented. As the plasmodium grows the blood-corpuscle becomes paler, and finally segmentation of the plasmodium begins, continuing until each segment becomes a small spherule, when the corpuscle bursts and the spores escape. Three forms of plasmodium are recognized,—namely, the tertian, quartan, and estivo-autumnal parasites, - though some consider The liquefaction of The sporozoan parasite Plural of plasmodisum.

The cycle of development within the body of the anopheles is as follows: When the mosquito takes the malarial blood into its stomach, flagellate forms (microgametocytes) are formed and their flagella (microgametes) are discharged, and, moving toward non-flagellate forms (microgametes), penetrate their bodies, thus fertilizing them. The fertilized form (zygole or szygocyte) penetrates the- stomach-wall and remains attached to the outer surface. Here they undergo change into rounded cystic bodies called meres or odcysts, which contain numerous spindle-shaped bodies (t/asts or sporo- 745
