TABLE 12 

 METABOLISM OF A PATIENT WITH INTESTINAL INFANTILISM (F. H.) 



The magnesium, like the calcium, is low in the urine and high in the 

 feces. In the urine of the normal boy, the quantity of magnesium is 56 

 per cent of that in the feces, while in the urine of the two patients with 

 infantilism it is only 20 per cent of that in the feces. The feces of the 

 normal boy contains about half as much magnesium as in the food; 

 whereas the feces of F. S. contains more than two-thirds as much, and the 

 feces of F. H. nearly as much as the food. 



The excretion of phosphates in the stools in intestinal infantilism is 

 larger and more marked even than that of calcium and magnesium. In 

 the feces of F. S. there is nearly three times as much phosphate as in the 

 urine; in the normal boy the ratio is just the reverse more than three 

 times as much phosphate in the urine as in the feces. In the normal boy 

 the feces contains about one-sixth as much phosphate as the food; the 

 feces of F. S. contains more than three-fifths as much. There is nearly
