Amount of 

 Social condition protein used daily 1 



Working class families of total weekly earnings under 26s. 89 grams 



,, over 26s. 119 



Servant keeping classes ...... 126 



Workhouses (including York) ..... 136 



Prisons. Class B ....... 134 



Convicts at hard labour . . . . . 177 



Atwater's standard . . . . . . 125 



Average from above physiological laboratory experiment 93 ,, 

 1 Calculated per adult man. 



Rowntree has adopted Atwater's standard and has concluded 

 that 27 / of the population of the city of York are living 'in poverty 

 partly on the ground that their protein diet falls below the At water 

 standard. Although it cannot be claimed that the numbers obtained 

 by us by urine analyses are strictly comparable to those given in the 

 above table 1 (which refer to bought food), yet the differences are so 

 great, and the actual nitrogen metabolism falls so far below the 

 Atwater standard, that great care must be taken in drawing conclusions 

 as to the sociological conditions from the amount of protein consumed. 

 It is hoped that we shall be able to extend this investigation in other 

 directions. 



1 It is also probable that the poorer classes take relatively larger quantities of vege- 

 table protein, in which cases the loss of nitrogen in the faeces is greater than 10 / , 

 the amount allowed for in our laboratory experiments.
