In the course of a study of the gum produced by the root nodule bacteria of legumes a close correlation was found to exist between the gum content of solution cultures of some species of Rhizobium and their viscosities as measured by means of an Ostwald viscosimeter. Certain cultures produced relatively viscid solutions while others showed practically no increased viscosity.
