We saw three dogs which were suspected by their owners ol 
having naturally acquired trypanosomiasis. All had, at some recent 
date, been in the fly country around N’dola, 15® S., 24*40' L, and on* 
examination showed trypanosomes and the clinical indications the 
disease a haggard appearance, anaemia, loss in condition, and in
