1. Sluggish phagocytosis of Plasmodium brasilianum by macro- 



phages in control of the American monkeys during the 

 acute rise of the malarial infection and the concentration of 

 P. brasilianum in Billroth cords of the spleen at the initi- 

 ation of the crisis 850 



2. Intense phagocytosis of Plasmodium brasilianum by macro- 



phages in Central American monkeys at the height of the 

 crisis of the malarial infection and malarial pigment, the 

 residue of parasites after the intense phagocytosis, in the 

 macrophages shortly thereafter 851
