of yeast and time is nearly constant. According to 

 these figures the rule of SCHUTZ nearly corresponds 

 to reality. For if we take the mean values of the 

 products in the three cases they are 21-3, 15-9 and 

 10-4, which are nearly proportional to the squares 

 of 1 200, 1000 and 800. If we divide the first 

 figures by 1-44, i-oo and 0-64 we find 14-8, 15-9 

 and 1 6- 2, which lie very near to each other. In 

 other experiments this regularity is less evident.
