Bates in 1913 and previously others have shown that in mala- 

 ria the loss of heemoglobin value corresponds very closely to 

 the reduction of red blood corpuscles. Therefore, the low hsemo- 

 globin index indicates a considerable deficiency in red blood 

 corpuscles in most of these persons. However, in view of the 

 fact that the majority of the persons in whose blood malarial 

 parasites were not found also had a low haemoglobin index, it 

 seems probable that the anaemia in these people was not due 

 wholly to malarial infection, but in part to their general poor 

 physical condition. 



In only 102 or 27.34 per cent of the 373 cases of malarial 

 infection were anaemic or regenerative changes in the red cor- 

 puscles recorded. These changes consisted of polychroma- 

 tophile corpuscles, basophile punctate corpuscles, and macrocytes. 

 In most cases these were not numerous, and in no case were 

 nucleated red cells observed. The changes in the red blood 

 corpuscles do not appear to be commensurate with the degree 

 of anaemia indicated by the haemoglobin value in many of these 

 persons. 



The results of differential leucocyte counts in 165 of these 

 cases of malarial infection are summarized in Table IV,
