SUMMARY: Different suspensions of Bacterium coli in distilled water, prepared by a routine technique and adjusted nephelometrically with reference to a ground glass screen, showed no significant difference in their viable counts at the 5% level. In a study of the inhibition by phenol of cultures grown in peptone water from inocula of such suspensions the regression line obtained by plotting the probit of the percentage inhibition against the logarithm of the concentration was rectilinear. From this the concentration needed for 95% inhibition was calculated.
