Abstract
1. The intramuscular administration of arsphenamine and neoarsphenamine is just as efficacious as the intravenous administration of these drugs in the treatment of experimental trypanosomiasis, as judged by both the minimum effective dose and the percentage of survivals of treated animals. The significance of this point in the treatment of human syphilis is discussed.
2. The ratio of the minimum lethal dose to the minimum effective dose M. L. D./M. E. D., is a substantial index to the curative power of a given drug under experimental conditions.
