The stud}^ beo-aii with ])reakfa.st, Wednesday, March 4, 1908, and 

 continued 7 da^^s, with 21 meals. The total nunil)er of meals taken 

 was 872, equivalent to 1 man for 291 days. 



The- same menu was served as during the two preceding studies. 

 The detailed statistics of kinds and amounts of food are g-iv^en in Table 

 35 of the Appendix. The data regarding the quantities of nutrients 

 and energy per man per day in the food eaten and rejected are sum- 

 marized in the following table:

[Quantities per man per day.] 



It was the opinion of the attendant in charge that these men were 

 light eaters. The results, as summarized above, show that, as com- 

 pared with some of the other groups, such was actually the case, there 

 being but 81 grams of protein and 2,657 calories of energy per man 

 per day in the food consumed. These amounts were, however, some- 

 what larger than in either of the two preceding studies. As before, it 

 was believed that the men ate all they needed. 



The food rejected contained 21 per cent of the total protein and 16 

 per cent of the total energy of the food served, or less than in the 

 two preceding studies, but still more than seemed necessary. A large 

 proportion of the waste protein came from meat. It will be seen 

 from the data in Table 35 of the Appendix that the wheat breakfast 

 food, as in other studies, Avas largely rejected, the proportion in this 

 case, 71 per cent of the amount provided, being even larger than usual. 

 A very large p.irt of the boiled "hominy and beans" was also rejected. 

 Apparently these foods were not relished. It is interesting to note, 

 however, that nearly half of the total protein and more than half of the 

 total carbohydrates consumed was supplied by cereals. The total 

 quantity of protein from vegetable food was twice that from animal 

 food, a proportion which is quite uncommon, as shown by the results
