 METABOLISM OF A NORMAL BOY (W. McC.) 



fat, rosy, cheerful, and, apparently, healthy boy who could run, and who 

 had excellent muscular control. His weight had increased from 13.6 to 20 

 kilos. But there had been almost no growth in size. There appeared to 

 be a striking improvement in the general health and nutrition of the soft 

 tissues. But the abnormalities referable to the skeletal system did not 

 improve; the bones remained small and fragile, and the patient did 

 not grow. 



Table 17 shows the result of a ten-day metabolism observation at 

 this time. 



With improvement in the general nutrition, the quantities of nitrogen, 

 phosphate, and magnesium in the urine have considerably increased and 

 the phosphate and magnesium of the feces decreased. The urinary calcium 

 is as low as in the earlier observation. The bulky stools with their large 

 calcium content still persist. 



These changes would seem to indicate that the failure to develop does 

 not depend upon a general nutritional disturbance, but upon some specific
