Discrssiox OF EXPERIMENTS. 



/. /. C., January 17, 1911. The results of the experiment are given 

 in table 210, from which it is seen that the increment in metabolism 

 continued throughout the four periods. The inference from the values 

 obtained would be that the effect of the food was still persisting at the 

 end of the experiment. This appears the more probable, for we have 

 here no uncertain basal value, as the post-absorptive metabolism values 

 were also determined on this day. It is clear, therefore, that with this
