In the first case (mouse No. 185) the treatment expelled the trypanosomes 
for a certain time, but later (in 11 days) there was a relapse and the animal 
succumbed. 
In the second case (mouse No. 28), after the injection into different parts of 
the body of mixed serum and trypanosomic blood, the animal appeared to be 
quite immune from infection (observation during 42 days). 
(2) and (3) Serum from trypanosomic rabbit and anti-anthrax serum. These 
sera not only failed to cure the mouse, but also there was no temporary 
expulsion of the trypanosomes from the blood.
