Average per individual 13'5gr. N excreted per day. 



Allowing for a loss of 10 % N in faeces, this is equivalent to 93 grams of protein 

 per day. 



There are several points of interest which are demonstrated by these 

 tables. The first of these is the constancy of the ratio of the uric acid 

 nitrogen to the total nitrogen. In five cases out of seven, the deviation 

 from the average of l'54/o is well within the limits of experimental 

 error ; in the other two cases the deviation does not exceed 0'09 %. 



Another point of interest is the relatively low total nitrogen excreted. 

 This is a point of considerable importance from the sociological 

 standpoint. The following numbers are taken from Rowntree's 

 Poverty, a study in town life, a study of social conditions in the town 

 of York.
