P.756 left column 3rd paragraph: "From literature data on bacterial cell content of protein, DNA, RNA, lipid, carbohydrate, and ash (primary sources 13, 20), and data on the specific gravity of these compounds (primary sources 1, 2, 20), one may estimate the specific gravity of bacterial dry matter to be in the range of 1.35 to 1.6 g/cm^3. Based on these estimates and on [investigators’] experimentally determined values for percent dry weight of cells, [they] have calculated the theoretical buoyant densities of bacterial cells. These calculated values were, in general, slightly higher than the buoyant density values determined by direct experimentation (Table
