It will be seen that the above dietary provided a .simple and tolera- 

 bly economical ration, with 45 per cent of the total digestible protein 

 and 29 per cent of the available energy furnished by animal foods. 

 Ordinarily in student dietaries studied in the United States, the pro- 

 tein from animal sources, as before stated, has been found to amount 

 to 60 per cent and the energy from the same .source to 43 per cent 

 of the total. The most noticeable item of expense was for combina- 

 tion meals, which amounted to nearly 40 per cent of the cost of the 

 day's food, or more than twice the average percentage expenditure 

 for the ten men included in this investigation. Since combination 

 meals were relatively cheap, this was a wi.se selection. The liberal 

 use of combination meals and the fact that Subject F secured (owing 

 to the almost exclusive use of white and Graham bread), for 1 

 cent spent on breadstuffs, about 19 per cent more protein and 15 

 per cent more energy than the average computed for the ten men, 

 are the chief reasons for the economy of the ration. He ate no cereal 

 breakfast foods, and only about 25 per cent as much meat and veg- 

 etables as the average. On the other hand, he was fully up to the 

 average on breads, while on desserts he was 25 per cent, and on bev- 

 erages 200 per cent above the average. The sums expended for the 

 last two articles are the only ones which could not be defended on the
