desirable. The average shows that 63 per cent, of the total 
proteid is animal, while 37 per cent, is vegetable. It is notice- 
able that Study E, with the highest total proteid — 161 grammes 
— has the lowest amount of proteid of vegetable origin. The 
animal proteid is 70 '4 per cent, of the total. In Study B, the 
animal is more nearly approximated to the vegetable, being 58 ‘4 
per cent, of the total proteid.

This result — the greater amount of animal proteid present — is in 
contrast to what was found in the Edinburgh labourers’ diet. 
As the result of fifteen investigations, Drs Noel Paton and 
Dunlop* found that the animal proteid was only 44*9 per cent, 
of the total proteid. 
(C) Energy Intake. 
If Table I. is again referred to, the high calorific value of the 
food is noticed. This is due in great measure to the large 
amount of fat present. In B, the comparatively small amount of 
fat is compensated for, as regards energy value, by the high 
carbohydrate. In each one of the studies, however, the energy 
value is considerably in excess of even Atwater’s liberal standard 
of 3520 Calories. 
(D) Cost of Diet. 
The average cost per man per day is here 15T pence (Table III.). 
In this, the cost of beverages and condiments is not included, as 
beer is only allowed for in two studies. The relative costs of
