58.7 grams protein and 3,075 calories per (Lay. In other words, the 
diet of the digestion experiment when the food was limited in kind 
was more generous than that of the dietaiy study when the food was 
selected at will. That the subject was benefited by the more abundant 
diet is indicated by the gain in weight of several pounds which he 
made during the time covered by the digestion experiments. 
DIETARY STUDY OF A VEGETARIAN (NO. 356.) 
The study commenced November 8, 1901, and ended December 1, 
lasting twenty-four days. The total number of meals taken was forty- 
eight, or two per day. The subject was a man 61 years old, height 5 
feet 7 inches, weighing 136 pounds. 
He stated that he had been a strict vegetarian for eleven years and 
that previous to that time it had been his custom to eat but little meat. 
He also said that he had led an active life, Avorking hard with brain 
and muscle. 
In Table 6 are given the results of this study.

The table shows that this dietary contains about one-third more pro- 
tein and nearly 12 per cent more energ} r than were noted for the pre- 
vious one. The corresponding figures for a man weighing 150 pounds 
would be 59 grams protein and 2,111 calories. 
The food eaten during this test, there is every reason to believe, rep- 
resents very well the normal diet of this subject, who throughout the 
whole experimental period (October, 1901, to April, 1902) remained 
in excellent health and strength. It thus seems that this man could 
maintain his health when the daily diet furnished onty 50 to 60 grams 
of protein, or about 60 per cent of the amount called for b} r the com- 
monly accepted standard for a man at sedentary work.
