In a recent communication (Penfold 1911) I described experiments with three organisms, B. coli Escherich, B. enteritidis Gaertner and B. Grünthal, showing that limitation or complete abolition of certain gas-forming powers normally possessed by these organisms, could be brought about by their growth on chloracetic acid-agar, and further, that in the case of the latter organism, resistance to this medium was associated with such limitation or abolition.
