 VARIOUS FORMS OF PLASMODIA. 



2d. Finely granular masses of protoplasm, which assume vari-

 in the centre ; at the end of a paroxysm it falls to pieces, the 

 pigment being then set free. 



3d. Oml bodies nearly the size of a red corpuscle, with long

Cultivation of these organisms has not yet been attained. 



Staining and Examination of Blood. Take the blood of a per
