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 6 hours before these observations. Sterile water was substituted 

 for food at subsequent times of feeding. 



3 Last feeding was about 18^ hours previous to these observations. Sterile water was given 

 in place of food at subsequent times of feeding. 



4 Last feeding was about 24 hours before these observations. Sterile water was substituted 

 for food at subsequent times of feeding.
