Table I. — I^'FLUENCE of Varying Amounts of Chloroform upon the 



Activity of Enzymes. 



In 100 lbs. total nitrogen. 



During 112 days the amount of soluble nitrogen varied within 

 very narrow limits in the different bottles. During the next 80 

 days the bottles containing 2.5 and 5 per ct. of chloroform 

 showed a little more soluble nitrogen than the others, in which 

 the amounts of soluble nitrogen were almost identical. These 

 results could hardly be interpreted as indicating, even after the 

 lapse of 192 days, any marked difference in the effect of definite 

 quantities of chloroform upon the activity of enzymes. The 

 germ content, as shown by bacteriological analysis, is in entire 

 agreement with the results of chemical analysis. 



From th^se results we see that in the presence of 2.5 per ct. 

 of chloroform the increase of soluble nitrogen is continuous and
