Chart 14.-»-Experiment 1590, represents the Temperature Curve of a Calf which has been 

 exposed in a Kraal contaminated by Amakebe. The phis and minus signs show the 

 presence or absence of Piroplasma higemiimm or the small rod and ring piroplasm in 

 the blood. 



Experiment 1593. 



To ascertain the Effect of exposing a susceptible Calf, as in the previous Experiment. 



Oct. 11, 1909.^ — This calf sent into Kampala. Oct. 17. — Eeturned from Kampala. 



The following chart represents the course of the disease, and the presence or absence of 

 Piroplasma higeminum or the small piroplasm in the blood : —

CiiAKT 1.5. — Experiment 1593, represents the Temperature ('urvo of at'alf which has been 

 expo.sed in a Kraal contaminated by Amakebe. The phm and minus .signs .show the 

 presence or absence of Piroplasma higeminum and the small rod and ring piroplasm 

 in llie blood. 



It Is evident, then, that the exposure of susceptible calves for a few days 

 in a kraal where Amakebe i.s common is followed by a serious illness. There 

 ifl high fever, glandular enlargement, emaciation, and, as a rule, death. This
