The tentative standard for a boy 10 }^ears old calls for 65 grams 
protein and 1,750 calories, and it will be seen that the daily diet (48 
grams protein and 1,558 calories) is far below it. It is, however, of 
more than passing interest to note that the present diet furnishes 
much more protein and energy than did that of the stud}^ previously 
reported/* which was made in the summer of 1900, which contained 
but 27 grams protein and 1,255 calories per day. It is true that at 
the time of the present investigation the boy was somewhat older and 
consequent^ would normally require more protein and energy, but the 
increase is about 65 per cent for the protein and 25 per cent for the 
energy, which is much greater than the difference in age calls for. 
The later diet was richer, presumably because it was more varied in 
character. In the previous study it was strictly fruitarian, while in 
the present case about 16 per cent of the protein and 10 per cent of the 
energy were of animal origin, and 32 per cent of the protein and 8 per 
cent of the energy were derived from cereals. In other words, in the 
present case the fruit and nuts supplied only about 56 per cent of the 
protein and 62 per cent of the energy of the diet. 
The use of the mixed diet was accounted for by the fact that for 
certain family reasons it was expected that the boy would in future 
live with relatives in the East, and as they were not fruitarians, or 
even vegetarians, it was deemed advisable to have the dietary include 
some of the more common foods in order to accustom him to their use. 
DIETARY STUDY OF A GIRL FRUITARIAN (NO. 358). 
The study commenced February 28, 1902, and ended March 20, last- 
ing twenty-one da}^s. The subject was a girl (sister of the subject of 
study No. 357) 8 years old, and weighed 37 pounds at the beginning 
and end of the test. 
Studies were made of the dietaiy of this subject during the summer 
of 1900, and again in the spring of 1901, both of which have been 
reported." As was then stated, her light weight and small measure- 
ments were presumably due in part at least to heredity, as her mother 
and grandmother were very small women. 
The total number of meals taken was forty-two, equivalent to one 
girl for twenty-one days or one man for eleven days.
