A comparison of waste cannot be made strictly, as the amount 
is bound to vary with many circumstances ; but so far as it goes 
it tends to show that the housekeeping in Edinburgh is more 
economical than in college residences in America. 
Of course it is impossible to compare the American and 
Edinburgh students’ results as rigidly representing the same class.. 
Students, even in the same university, are by no means similarly 
situated as regards the amount of money which can be expended 
on living generally, and on food in particular. It would be 
absolutely erroneous to conclude that the average amount spent 
by students in Edinburgh or in other Scotch university towns in 
any way approaches the expenditure given in these studies. Dire 
necessity limits the expenses of many Scotch students. The 
fairly close correspondence in the studies given is of no little 
interest. With increased expenditure on food, the nutritive 
value of food does not necessarily rise. This has already been 
shown in Table V. The tendency is probably not so much to 
increase the quantity of food eaten as to get a better quality, and 
to use more expensive articles of diet. If the question of cost 
has not to be considered, there can be no possible objection to 
this. But in the great majority of cases, all over the country, the 
struggle for existence is so keen that money spent needlessly on 
food cripples the funds for other requirements. A knowledge of 
true economy in food is then of the highest importance. 
A study of the food-materials used shows that on the whole 
they were those ordinarily used in middle-class dietaries, and
