relation to one another are shown in the figure 

 (Fig. 14). 



Further, there is a certain amount of evidence 

 to shew that a gamete (?) in the blood can undergo 

 a kind of retrogressive development, and give rise by 

 parthenogenesis to young parasites (i.e., schizonts). 

 If this is so, it would explain the supposed function of 

 old attributed to crescents (gametes) of producing 

 relapses. 



There is no evidence at present that the parasite 

 passes into the ovum, giving rise to hereditary trans- 

 mission.
