Chart 6. — Experiment 556 represents the Temperature Curve of a Calf which has been 

 Injected with Blood containing tlie Small Rod and Ring-shaped Piroplasm. The 

 minus and plus signs show the absence or presence of the small rod and ring-shaped 

 piroplasm in the blood. 



Remarks. — Twenty-four days after the injection of the blood containing the small 

 piroplasm, the same rod and ring forms appeared in the blood. The temperature curve 

 hardly shows any response to the invasion of the parasite, and the calf shows no signs of 

 illness. It is evident, then, that the injection of blood containing this small piroplasm 

 gives rise to no symptoms like those seen in Amakebe. 



Ill the same way the injection of blood containing Piroplasma higeminum 

 is followed, after some days, by the appearance of this parasite. 



Experiment 1901. 



To ascertain if the Injection of Blood containing Piroplasma higeminnm will give rise to 



Symptoms of Amakebe. 

 Aug. 20, 1909. — Injected 2 c.c. blood containing Piroplasma higemiimm into this calf.
