Notes on Nagana and on Some Haematozoa observed during my travels

Abstract

1. Some cases of remarkable resistance to nagana infection are recorded. 2. Although such birds as pigeons are unable to harbour the trypanosoma brucei, the kestrel is able to do so. 3. Attention is drawn to certain changes which are brought about by the trypanosome infection and the need for more precise chemical investigation of these haematozoal diseases.
