As the result of these experiments it will be observed that acid 

 causes a very marked acceleration of autolysis, whereas alkalis have a 

 strong inhibitory action. Bicarbonate of soda acts as a weak alkali in 

 this respect. The curves representing Series V (a) and V (f) are given 

 in the accompanying diagram. 



Series V (^). The effects of sulphuric acid with varying solutions or 

 varying quantities on the rate of autolysis. 



In the following experiment 20 c.c. of H 2 so 4 solution were used 

 in every case :
