The initial concentration was .85, the pH range after inoculation was to , and the concentrations of organisms was determined at the end of eight days. The results obtained are very similar to those of Series III, and they are also given in Fig. 2. The optimum at pH will bear SERIES IV. 2 4 56789 10 PH I-'K;. 2.

Since the pH values of the tubes of Series IV correspond exactly to those of Series III, corre- sponding values were averaged, and the results were plotted as Curve V of Fig. 2. The curve shows a decidedly greater amount of growth be- tween pll and pH than in the more alkaline range. The opti-.
