1. Trypanblau injected subcutaneously into dogs a day before or a day after they have been inoculated with blood containing Piroplasma canis effectually prevents the development of piroplasmosis by destroying the parasites at the onset of infection.
2. Trypanblau given by the mouth is ineffective, since it exerts no apparent influence either upon the parasite or upon the course of the disease.
3. Tryparosan, when injected subcutaneously or when given by the mouth, has no effect upon the parasite and is ineffective as a remedy against piroplasmosis in the dog.
