Trypanrot treatment. 
O Received 3 doses of Trypanblau. 
f Received 2 doses with 1 day’s interval between the injections. 
- before the numbers in column (c) indicates that the parasites may have disappeared

In the above table we have not included Dog 1, which was treated

It will be noted that in the two Dogs 10 and 11, in which a relapse 
occurred, the parasites reappeared after a shorter interval than in any of 
the other animals.
