On the Liquefaction of Gelatin by the Bacillus Cloacae

The Bacillus cloacae liquefies gelatin very slowly, sometimes taking a month or more to do so. It is in consequence occasionally a source of delay and of great inconvenience to the bacteriologist. In this paper it has been shown that by using appropriate methods the time necessary for demonstrating the liquefaction of gelatin by this organism may be shortened to a week.
