We may take 500 grammes of bread and 250 grammes of lean 

 meat as a fair quantity for a man fit for hard work. Adding 500 

 grammes milk, 75 grammes oatmeal (as porridge), 30 grammes butter, 

 30 grammes fat (with the meat, or in other ways), and 450 grammes 

 potatoes, we get approximately 20 grammes nitrogen and 300 grammes 

 carbon contained in 135 grammes proteid, rather less than 100 

 grammes fat, and somewhat over 400 grammes carbo-hydrates. 

 Thus: 



This would be a fair ' hard work ' diet for a well-nourished labourer. 

 But the great elasticity of dietetic formulae is shown by comparing 

 the ration of the English and German soldier as given in the follow- 

 ing tables :

* This is given in Parkes's ' Practical Hygiene ' as the usual dietary of 

 the English soldier on home service. The free ration includes only 

 one pound of bread, but the soldier buys, on the average, an extra 

 half-pound.
