Calculated from the weight of carbon dioxide produced during the period. The preliminary 

 periods for all days are omitted in computing the minimum metabolism. See table 31, p. 142. 



2 Last feeding was about 3 hours previous to these observations, sterile water being given in 

 place of food at the next time of feeding. 



3 On June 19 and June 21 last feeding was about 6 hours before the observations. Sterile 

 water was substituted for food at subsequent times of feeding. 



4 Last feeding was about 5^ hours before these observations. Sterile water was substituted 

 for food at subsequent times of feeding. 



B Last feeding was about 19^ hours previous to these observations. Sterile water was given 

 in place of food at subsequent times of feeding. 



6 Last feeding was about 24 § hours previous to these observations. Sterile water was sub- 

 stituted for food at subsequent times of feeding.
