 gives the age of the infant during the metabolism observations.

RESULTS OF OBSERVATIONS ON THE GASEOUS EXCHANGE. 



With an investigation extending over so many months and dealing 

 with so many subjects as were used in this research, it is obviously 

 impracticable to present protocols for each observation. On the other 

 hand, as the carbon-dioxide production, oxygen consumption, pulse- 

 rate, and muscular activity were accurately recorded in each experi- 

 mental period, it seemed desirable to present the data in permanent 

 form. This is done in table 23. 



Accordingly, the carbon-dioxide production per hour, respiratory 

 quotient, average pulse-rate, and the estimated activity are given for
