In Fig. 2, the reaction resultant is derived from large numbers of fermen- tations in which B. perfringens has acted on glucose peptone water containing various added amounts of hydrochloric acid. - In the figure, only fifteen points are shown owing to lack of space, but we have many other confirmatory points from additional experiments. It will be observed that the points recording the final values of P^ lie very close to the smooth curve that has been drawn to represent them, and estabhsh quite definitely the form of this line. 50. 90 ~ REACTION RESULTANT.
