the latter, on the other hand, are not completely expressed by the 

 amount of carbonic acid set free. 



Curve 1 contains the average of the determinations of 4 series, 

 of which one series is noted separately as curve 2. The differences 

 between these two curves are exceedingly slight owing to the regular 

 mode of life and the uniformity of the food. 



Two of the four series are from November-December 1907, the

two others from May 1908. As I could only make one, at most two 

 experiments on the same day, the curves are compounded of experi- 

 ments on different days, by which means the firmness of the type 

 is further strengthened. The 3 maxima of the curve occur imme- 

 diately after the principal meals of the day. 



Curve 3 shows the corresponding changes in the reclal tempe- 

 rature. The curve is based on measurements made at the same 

 time as the respiration experiments and, though to a less degree, it 

 displays fluctuations up and down corresponding to those of the 

 CO, -curve. In the last series of experiments I was imprudent enough 

 to take the temperature in an upright position (in the curve given 

 only the morning temperature was taken while lying down), which 

 often gives too high values owing to stasis; this is certainly the
