1917-18.] A Further Study of Labouring Class Dietaries. 47 
it would seem that the maximum consumption of bread stuffs has now 
been reached. 
These studies throw light upon the proportion of energy which such 
families derive from the foods it is proposed to ration — cereals, meat, fats, 
and sugar — and those which it is not proposed to ration. 
No less than 86 per cent, of the energy was obtained from the rationed 
foods, although in 1915-16 they yielded only 75 per cent. It would thus 
seem that, when the price of the unrationed foods is high, as at present, 
the urban labouring classes cannot be expected to derive more than 14 or 
15 per cent, of the necessary energy therefrom. 
It is of interest to note that in the three families where the father was 
on military service, the diet was more adequate than when he was at home. 
In conclusion, I should like to thank Professor Noel Paton for all the 
assistance which he has given me.
