gametocytes, whose effilated extremities have a distinctly granular 
structure, indicate that an “ ectoplasm ” exists quite distinct from the 
periplast. In the young parasite its tendency is to stain blue; in 
the adult it is pink. 
The “ endoplasm ” is the most striking part of the whole parasite. 
So much so that it, with the nuclear bodies, has been described by 
some as the whole of the parasite. In the makrogametocytes the 
endoplasm stains a deep blue (fig. 73). It frequently contains large 
numbers (20-30) of coarse, or fine, vividly chromatophilic granules 
and many small, circular non-staining areas— “ vacuoles.” The 
endoplasm of the mikrogametocytes (fig. 49) stains much less deeply, 
and rarely contains granules or vacuoles. The endoplasm appears 
to consist of a system of wide alveoli filled with a more or less 
granular protoplasm. This structure is particularly well seen in the 
makrogametocytes. The sexual variation in the endoplasm exists, 
though in a minor degree, in some of the smallest parasites (endoplasm 
measures 4//, by 3/i). 
The form of the nuclear bodies ” varies enormously, according 
° the sex and stage of development of the parasite.
