structureless protoplasmic bodies much smaller than, and within 

 or attached to, the red blood- corpuscles (Fig. 2.33). These rapidly 

 change then' shape, exhibiting amceboid movement. They were 

 first described by Marchiafava and Oelli, and possibly represent the 

 first stage in the life-history of the hfematozoon. Marchiafava and 

 Celli suggested the name Plasmodium malarife. Second, minute

masses of finely granular or of hyaline protoplasm enclosing granules 

 of pigment (Fig. 234). These forms are sometimes present in large 

 numbers, and at other times can be found only with difiiculty. 

 They are more or less spherical, but exhibit amoeboid movement, 

 and rapidly change their form. The pigment granules are also in 

 active movement. There may be one or more of these amceboid

bodies to a blood-corpuscle, and they vary in size ; one may occupy 

 the whole of the corjjuscle. In cases of pernicious malaria, similar 

 bodies may be seen, in tissue sections, in the corpuscles filling the 

 capillaries. Third, forms which appear like isolated grains, and 

 larger homogeneous bodies surrounded by clear spaces which change 

 in outline. 



Extra-corpuscular bodies These are the most striking, and
