In the preceding report (Topley and Ayrton, 1923 b) it has been shown that, if various strains of B. aertrycke be fed to mice and the subsequent events observed over a period of 42 days, and if all strains fed to the mice or isolated from their faeces or tissues be examined as regards their type of growth and their agglutination reactions, then the following associations are found to exist between the characters studied. The presence of group antigen is associated with persistent faecal excretion, whether the strain be rough or smooth. Roughness is associated with decreased faecal excretion and a decrease in the percentage mortality, when rough strains are compared with, smooth.
