B. Segregation of cases, 
This is a most necessary precaution. Cases of trypanosomiasis 
exist in the country and tsetse flies are widely distributed, in one 
instance, at least, being fairly plentiful in the village in which an 
infected man was living. 1 he practical application of gland 
palpation and puncture are the means to be adopted in hnding the 
cases. Dutton and Todd^ pointed out that any European, or even 
intelligent native, could apply the method. While it cannot be 
doubted this is possible, it would be advisable not to rely on the 
chance assistance of either of these. Even with the best of 
intentions, the majority of Europeans would not fully appreciate the 
importance of the issues involved, and would soon tire of practising 
it. A dependence on results thus obtained would only lead to a false 
sense of security. Again, the fact that enlarged glands in this 
country does not necessarily mean trypanosomiasis is another reason 
why the work should be left in the hands of trained medical officers. 
The saving of time where palpation and puncture can be done on the 
spot, and the consequently lessened danger of having possibly 
infected people travelling through the country to the nearest medical 
officer, are facts worthy of consideration. At the present date it 
appears probable that cases are scattered over a wide area of the 
territory ; therefore we would suggest that a sufficient number of 
special medical officers be appointed to travel systematically through 
all the villages palpating all the natives and puncturing those in which 
this was indicated. In the event of cases being discovered, they 
should at once be removed to a segregation camp for treatment 
Before leaving their villages, or, in fact, as soon as the diagnosis had 
been established, they should be given a full dose of atoxyl, 
preferably intravenously. This would drive the trypanosomes from 
the peripheral circulation — Koch^^ slates for at least 30 days—and 
would prevent the possibility of infected persons acting as 
disseminators of the disease on their way to the camp. 
It must not be thought that one visit to a village will be sufficient. 
Two of the cases we found only escaped earlier detection by reason 
of the fact that they were absent from their villages when these were 
first visited. 
The districts into which the country is divided for this purpose 
should not be so large as to make it impossible for the medical officer
