THE CHROMATIN MASSES OF PIROPLASMA BIGEMINDM. 313 



two easily distinguislied pairs are shown, which would appear 

 almost certainly to have resulted from a multiple (binary) 

 infection. In text-fig, 31a group of three parasites is repre- 

 sented, all differing to some extent. Such groups are rare. 



The general distribution of the chromatin in groups of 

 parasites conformed to that already given.

Parasites in process of division were not common. In

figured previously, but without showing the blepharoplast 

 in the partially separated forms. In this dividing parasite 

 two nuclei, " polar '^ in position, and two blepharoplasts, 

 "apical" in position, were clearly seen. 



In text-fig. 83 nuclear division is depicted in a large, ovoid 

 form. The principal nucleus is here drawn out into a some- 

 what curved rod, with slightly enlarged ends, the outline of
