considered to be free of disease, it was by gland puncture alone that 
its existence was demonstrated. 
We are indebted to Mr. Lane, the Veterinary Officer of North 
Eastern Rhodesia, for the following summary of results since adopting 
this method of diagnosis. The trypanosome with which he had 
chiefly to do is, in animal reaction and morphology, related to 
T. nanum. On one Station four cases were diagnosed by gland 
puncture: in no instance were trypanosomes seen in the blood. On a 
second Station, in five cases the gland juice was positive, while only 
two showed organisms in the blood.
