values all lie very close to 200 c.c. If we exclude the first period, we 

 find no evidence of change in the value as the day progresses. A closer 

 examination of the figures shows that the high value on the first day is 

 determined, in part at least, by values on May 3 and 7, on which the 

 carbon dioxide excreted was 252 c.c. and 246 c.c., respectively, both 

 values being considerably higher than those found on the subsequent
