E. tartar emetic; A. atoxyl; T. trypan-blue; D. trypanil (dianil-blue). 
Thus, combined treatment with tartar emetic, or atoxyl, and trypan-blue 
or trypanil, did not produce positive results. 
Neither did combined treatment by stages produce any good results. 
Preventive treatment. This treatment has been applied in two ways: 
(a) At first the preparation was injected, and then simultaneously, or 
after a certain interval, the animal was infected. 
( b ) The animal was at first infected, and then simultaneously or after a 
certain interval the preparation was injected. 
Infection was made subcutaneously, and the following preparations w T ere 
introduced: tartar emetic, intravenously, and trixidin, subcutaneously. The 
dose of tartar emetic was 1 : 1200 solution, and of trixidin 1 : 500 and 1 : 250. 
The results were unsatisfactory. We are continuing the experiments on 
chemo-therapy. 
Serum. Besides chemical preparations, we have also tested different kinds 
of serum: (1) human, (2) from rabbit infected with the camel trypanosome 
and (3) anti-anthrax serum (from horse). 
(1) Human serum. Serum was obtained from a healthy woman. It was 
applied both for curative and preventive purposes.
