GASEOUS METABOLISM OF INFANTS. 



Table 23. — Results of observations on the gaseous exchange of infants — Continued. 



[I, Very quiet, probably asleep; II. Slight movements, few in number; III, Some activity, but 

 generally quiet; IV, Moderately active; V, Distinctly active; VI, Very active, most or 

 all of the time.] 



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. 



While the data given in table 23 are made the basis of the discussion 

 of our results in Part III of this publication, they may likewise be used 

 for the discussion of many problems which have not been considered 

 at this time. Furthermore, observations are still in progress in which 

 supplementary evidence is rapidly being accumulated. Hence we wish 

 it clearly understood that the data in table 23 are recorded here not 

 only for present use, but for deferred discussion, in another place, of the 

 many problems connected with the study of the metabolism of infants, 

 such as the influence upon metabolism of crying, intense muscular 

 activity, subnormal or febrile temperatures, and various distinctly 

 pathological conditions.
