Abstract
1. Twenty-six passages from rat to rat have been effected without recourse to artificial media. The time taken was 89 days. 2. Our results furnish no evidence that the virulence of the bacillus used for the passages undergoes any alteration. 3. The experiment gives evidence of the varying susceptibility to plague of the Bombay rat.Keywords
