GASEOUS METABOLISM OF INFANTS. 



SELECTION OF DATA USED FOR COMPARISON. 



From the data obtained a table has been compiled which gives 

 the average result of the periods with each infant in which the metab- 

 olism was at a minimum (see table 31). The selection of the periods 

 was based upon the records of the pulse-rate and the muscular activity, 

 only such periods being used as showed a normally low pulse-rate and 

 practically no muscular activity, i. e., those characterized as I or II. 

 The figures for the ages and weights are the average ages and weights 

 for the experiments included in the table. The data are arranged 

 according to the increasing weights of the infants. Since with one

iln accordance with the usage of Continental writers, we give these values, although we 

 believe they are peculiarly liable to misunderstanding, and hence their use is unfortunate. 

 *The activity estimated for these two periods was II and III, respectively.
