Several other results are given, hut they are not quoted, as waste 
material is not considered. 
The average result for the present studies is: proteid, 143 
grammes; fat, 138; carbohydrate, 511 ; Calories, 3978. With the 
single exception of the fats, this is higher than the American work, 
although the high energy value of fat makes the total calorific 
results closely resemble each other. The disparity between the 
American and the Edinburgh dietaries is most noticeable in the 
women’s studies. The Edinburgh women students consumed a 
greater amount of proteid and carbohydrate, and their food had a 
higher Calorific value. 
The Japanese proteid and fat value, especially the latter, are 
noticeably small, and are both the result of the low animal intake, 
but it is necessary to remember the small stature of the Japanese. 
In connection with this comparison between British and 
American dietaries, it is noteworthy that Atwater refers to the 
American of the same social position as being more abundantly 
fed than the Briton. He believes that the American is more 
energetic and able, and he attributes this to the more abundant 
food-supply. His conclusions are hardly borne out by the investiga- 
tion into the proteid supply of labourers in Edinburgh. These men 
have as much proteid daily as the labouring class in Philadelphia 
and New York, although their supply is less than people of the 
same condition in Chicago.! If we accept Chittenden’s view, the 
additional proteid is an evil instead of an advantage.
