We see from the above table a progressing rate of autolysis with 

 an increasing strength of acid up to the concentration of ^. Concen- 

 trations above this strength appear to be destructive to the enzyme. 



i. By autolysis in this and the succeeding experiments, up to Series V (g), is meant the N in the 

 filtrate after coagulation.
