1905-6.] Miss I. D. Cameron on A Dietary Study. 
Atwater’s estimate — a woman is regarded as eating 08 times 
as much as a man. In Study E the students were women, 
so each member of the household was calculated on the 0*8 
basis. 
As the nutritive value of beverages and condiments is small, 
and their composition varies somewhat, they have not been 
included in the general results. The amount expended on these 
two items has been calculated separately. In two of the studies 
— A and D — the cost of beer is included in the beverages. In 
the other three studies, beer is not considered. 
Five halls of residence were studied, by the kind co-operation 
of the housekeepers, w r ho undertook the arduous work of keeping 
accurate accounts of the amounts purchased, and seeing that the 
waste was collected. 
The studies represent collectively the dietary of 1129 men for 
one day. Allowance in each case was made for absence from 
meals, and for the presence of guests. 
.Study A = 239*4 men for one day ( 31 men, 8 women).
