B Quinine was administered at 4 o'clock in the afternoon. 



It will be observed in Table XVIII that, while there is some 

 correspondence between the ratios of increase and decrease ob- 

 served in No. 727 by the different methods, the results are at 

 variance, especially on the third day. It seems probable that 

 there was, at least, a diminution in the rate of increase of the 

 parasites on that day. Probably the results given by the thick 

 films are more reliable. The probable error is great in basing 

 results on these small samples, whatever the method used. The 

 results may give us some notion of the rate of increase or de- 

 crease of parasites, but only an approximation as to their abso- 

 lute numbers in the peripheral blood. 



In both cases the parasites examined carefully in thin films 

 were evidently subtertian. No crescents were observed in either 

 experimental case.
