CULTIVATION OF T. UNIFORME. 
No attempt was made to cultivate 7. wniforme. 
CARRIER OF T. UNIFORME. 
No experiments were made in the laboratory with Glossina palpalis as a 
carrier of 7’. wniforme, and no evidence is to hand as to what the carrier is. 
CONCLUSIONS, 
1. Trypanosoma uniforme resembles TZ. vivax in shape and _ general 
appearance, but differs markedly in size. | 
2. It also resembles 7. vivax in not being pathogenic to the smaller 
laboratory animals. 
3. There is no evidence available, as in the case of 7. vivax, as to what the 
earrier of 7’. wniforme is.
