what he regards as the greater working power of the American. 
As illustrative of the wide range of difference in the studies 
collected in America,* a low and a high dietary may be 
quoted. 
A seamstress, whose diet was studied by Playfair, consumed 
daily 53 grammes of proteid, 33 grammes of fat, and 316 
grammes of carbohydrate (energy value, 1 820 Calories). A 
Californian student football team used 270 grammes of proteid, 
416 grammes of fat, and 710 grammes of carbohydrate per man 
per day (energy value, 7885 Calories). It is needless to remark 
that this huge amount was taken during training. Jaffa, who 
reports this study, says that “ the study seems, on the whole, to 
warrant the conclusion that the team was overfed.” 
A number of American middle-class dietaries, including studies 
of men and women university students, will be referred to 
later. 
The dietary of public institutions has been worked out 
in a number of cases. Aitchison’s Investigations into the 
Diet of a Scotch Workhouse and Smith’s Report of Dietaries 
of Lunatics and Workhouses are examples of this kind of 
work. 
A Royal Commission was appointed to inquire into prison 
dietaries, and their report was presented to the Houses of 
Parliament in 1878. The diet of soldiers was the subject of a 
Royal Commission inquiry, and a report on the subject was 
submitted in 1889. This contains suggestions for the improve- 
ment of the quality of the diet, and a comparison with the army 
dietary in other European countries. The British allowance 
was shown to be greater than that of the Continental armies. 
A soldier’s daily allowance was then made 113 grammes of 
proteid, 38 grammes of fat, and 482 grammes of carbohydrate 
(Calories, 2793). De Chaumont considered this diet deficient, 
and thought that the allowance ought to be increased, especially 
in the case of the younger soldiers.

Station , 1900.
