ent compounds in the urine indicates whether the protein metabolism is 

 relatively high or low. 



Tables 1 and 2 from Folin's paper on this subject (Folin(rf) ) show the 

 nitrogen -and sulphur distribution in two typical cases of high and low 

 protein diet respectively. ,,

 NITROGEN AND SULPHUR DISTRIBUTION IN THE URINE ON A HIGH PROTEIN DIET 



TABLE 2 

 NITROGEN AND SULPHUR DISTRIBUTION IN THE URINE ON A Low PROTEIN DIET 



Tables 3 and 4 show the nitrogen and sulphur distribution in the urine 

 in two cases of intestinal infantilism (McCrudden and Fales(fr)). 



The nitrogen in the form of urea and the sulphur in inorganic forms 

 are very high in comparison with the nitrogen and sulphur in other forms. 

 Such figures prove that the exogenous metabolism is high and indicate that 

 the endogenous metabolism is not excessive. They show that the patients 

 are probably absorbing sufficient protein for their metabolism. 



Despite the normal figures for nitrogen and sulphur distribution, the 

 other factors pointing toward some form of starvation were suggestive 

 enough to make further studies in this direction advisable. The -large 

 amount of nitrogen in the f eces compared with the urinary nitrogen are 

 especially noticeable. Table 5 shows the figures in two cases of intestinal 

 infantilism, and, for comparison, in one normal boy (McCrudden and 

 Fales(6)). 



In the case of F. S. the nitrogen in the feces is over two grams a day. 

 In the case of F. H. the absolute amount of nitrogen is not greater than in 

 the normal boy, but, since he was excreting only half as much per day in 

 his urine, the relative amount is twice as great. In the case of F. S. the 

 fecal nitrogen is 38 per cent of that in the food; in the case of F. H., 11 

 per cent. In the normal case it is only 7.5 per cent. The usual average
