292 Sir D. Bruce and others. Trypanosome [Feb. 8, 



This curve is made up of measurements from 80 specimens of trypano- 

 somes taken from the goat, 160 from the monkey, 260 from the dog, and 

 1000 from the rat. It resembles that of Strain I, and differs absolutely 

 from Strain II. 



As in the case of Strain II, E , a curve is also given of 1000 



individuals of this strain.

 1000 Individuals of the Trypanosome of Strain III, Chituluka.

This curve, made up of 1000 individuals, is very similar to the previous 

 one of 1500. It is made up of 80 specimens of trypanosomes taken from the 

 goat, 160 from the monkey, 260 from the dog, and 500 from the rat. 



The two following curves represent measurements of 500 trypanosomes 

 taken from each of two rats.

 500 Individuals of the Trypanosome of Strain III, Chituluka, taken on nine consecu- 

 tive days from Eat 952.
