CARNEGIE INSTITUTION OF WASHINGTON. 



Taking a general average of all of the results except the single group 

 at 40° to 41° C, we find that at one end the average ratio of 0.46 (with 

 an evolution of carbon dioxide amounting to 0.88 c.c. per gram fresh 

 weight per hour), while at the other end (with an average ratio of 

 about 1.00) the amount has more than doubled. It is more satisfactory, 

 however, to follow the rates and ratios of a single temperature group, 



Tabidation and averages of ninety-six gas-interchange experiments, arranged 

 according to -j=r— ratios.
