PREVIOUS STUDIES OF THE METABOLISM OF CHILDREN. 17 



Auguste Victoria-Haus, are of special value. Niemann's data are 

 reported in table 9.

Frank and Niemann, 1913. A very much undernourished male 

 child, 3 months old, was studied by Frank and Niemann 1 in a respira- 

 tion chamber after being fed for 6 weeks on breast milk and again 

 after 4 weeks' feeding with cow's milk. The results have no special 

 interest in a study of the normal respiratory exchange of normal 

 children. 



Murlin and Hoobler, 1915. Employing an apparatus essentially 

 that formerly described by us, Murlin and Hoobler 2 studied some 

 hospital cases, of which several are considered by them as perfectly 

 normal. 3 The values computed for the minimum heat production 

 per square meter per 24 hours, using the more accurate Lissauer method 

 of computing, are given in table 10. From these cases and 14 previ-

ously published by us, they discuss extensively the metabolism in 

 relation to several physiological factors.

3 One of these subjects, E. N., we would exclude from consideration because of underweight; 



likewise, we would question considering M. M., who, according to the authors, "no doubt 

 had an incipient tuberculous infection."
