The statistics reg'ardinjjf the <iuantities of food provided, eaten, 

 rejected, etc., are given 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 summarized in Table 7. Considerable 

 difficulty was experienced in this study in separating the different 

 kinds of food rejected so as to get the weights of each. Frecjuently 

 allowances and estimates had to be made, and though in some cases it 

 was almost impossible to make satisfactory estimates, this was done as 

 carefully as possible, and the data as recorded are believed to be not 

 far from correct.

[Quantities per man per day.] 



The quantities of nutrients and energy per man per da^' in the food 

 eaten during this study were larger than was to be expected, being 

 very nearl}^ the same as in study No. 3T1, which was also made with 

 patients more or less infirm. From a comparison of the figures in the 

 table above with those in Table 6 it would appear that the quantity of 

 carliohydrates, and consequently of energy also, was considerably 

 smaller in the present study than in No. 371, but unfortunately the 

 amount of sugar consumed was not learned. The observer was able 

 to ascertain, however, that it was not large, but was probably as 

 much as would make the total energy of the food consumed about the 

 same as that in study No. 371, and certainly fulh^ sufficient for the 

 needs of the patients. 



In this study, as in No. 371, the protein furnished by milk was 

 large, being as much as the total from all vegetable foods. Eggs also 

 formed a noticea1)le part of the diet, and properly, because though 

 not always a cheap food, the^^ are of special value in the diet of the
