Comparison of the Curves of the Wild-game Strains. 



Unlike the curves of the Human strains, these are all remarkably alike, and 

 there can be little doubt that the same species of trypanosome is being dealt 

 with in all five of the Wild-game strains. The Wild-game curves resemble 

 Strains II, IV, and V of the Human strains, described in a former paper, and 

 also those found by Kinghorn and Yorke in the Luangwa Valley.
