following particulars as to the results obtained 

 with small doses. 



As Laveran had shown, the normal serum 

 caused the parasites to disappear, but, after 

 a varying period, they again made their appear- 

 ance and generally soon afterwards caused 

 death. In cases in which ^ to T ^- c.c. of serum 

 was injected, the results in the majority of sera 

 tested were extraordinarily constant, in the 

 other cases death occurred between the tenth 

 and fourteenth day. 



The cases were as follows : 



Normal Serum I., death on the twelfth day. 



Normal Serum II., death on the twelfth day. 



Diabetes mellitus, death on the twelfth day. 



Acromegaly, presumably between the tenth 

 and eleventh day (0*0625 c.c. caused death on 

 the ninth day). 



Concretio cordis, death on the eleventh day. 



Colica saturnina, death on the eleventh day. 



Polycythasmia rubra, death on the twelfth 

 day. 



Carcinoma of stomach with metastases in the 

 liver, death on the thirteenth day. 



Peritoneal tuberculosis, death on the thir- 

 teenth day. 



Leucaemia myelogenica, death on the four- 

 teenth day.
