so it is perhaps not too much to assume that these results 
may he taken as fairly representative of the diet of this class, 
giving as they do the food consumed by over a thousand 
men in one day. The expenditure also approximates to the 
average middle-class expenditure. 
The only accurate account that I could obtain of the expenses 
of a private well-to-do family has been put at my disposal by a 
lady who has kept a detailed account of her household for five 
years. This works out at 11s. 4d. per man per week, but in this 
no allowance is made for the presence of guests and for special 
food in time of illness. 
Most people, when asked, give 10s. a week as an average middle- 
-class food allowance, and the average in the present study is 
9s. 2d. per week. This lower figure may be due partly to co- 
operation in diet, with the possibility of contract prices ; but as 
the data for comparison are uncertain, it is, unfortunately, 
impossible to emphasise this important point. 
V. Summary of Results. 
1. The diet of five halls of residence was studied. This 
represents the food of 11 29 ’4 men for one day. 
2. The average amount taken per man per day was : proteids, 
143 grammes; fats, 138 grammes; carbohydrates, 511 grammes; 
with a fuel value of 3979 Calories. 
3. In all the studies the proteid value is high. The animal 
proteid is 63 per cent, of the total proteid. 
4. The average cost per man per day (exclusive of beverages 
and condiments) is 15T pence. Sixty-six per cent, of this is 
■expended on animal food. 
5. The amount of nutritive material per penny is much 
lower than that given in the study of the diet of Edinburgh 
labourers’ families. 
6. The waste varies considerably. The approximate cost of 
waste was from 2’4 per cent, to 7 per cent, of the total money 
spent on food. 
7. The proteids and carbohydrates are higher than in the 
American college studies. As the fats are lower, the Calorific
