The discussion of the preceding dietary showed that more protein 
and energy were furnished by the restricted daily diet during the 
digestion experiments than by the food consumed by the same subject 
during the period of the dietary study when he ate food chosen at will. 
As may be seen by a reference to Table 46, page 61, like conditions do 
not obtain for the subject of the present study. On an average the 
daily food eaten during the 16 digestion experiments furnished 44.01 
grams protein and 1,831 calories. In other words, when the subject 
selected his daily food at will he ate somewhat more than was the case 
when his diet was fixed upon for experimental purposes. 
DIETARY STUDY OF A BOY (NO. 357). 
The study continued for twenty-one days in March, 1902. The sub- 
ject was the same boy as in dietary study No. 331, previously reported/' 
and was now 10 years old. He weighed 58 pounds at the beginning 
and at the close of the stud} r . 
The number of meals eaten was forty-two, equivalent to one boy for 
twenty-one days or one man for thirteen days. 
The details of the study are shown in Table 7.
