feces the availability of the diet as a whole and of the cereal 
portion of the diet alone was calculated, as explained more 
fully hereafter. The details of the experiments are-given in 
the paragraphs which follow. 
List of experiments.—A list of the experiments, showing the 
subject, date, duration, and kind of cereal food in each, is given 
in the following table.

Subjects. — The subjects of the experiments were five young 
men in good physical condition and with apparently normal 
digestion and nutrition. Three of them, EK. O., H. C. S., and 
R. D. M., had previously been subjects of digestion experi- 
ments, and the other two, as a result of their experience in the 
laboratory, fully understood the nature and requirements of 
such experiments. 
Occupation.—All of the subjects of the digestion experiments 
were engaged in light work in connection with the nutrition 
investigations, and each one took some physical exercise each 
day. The total daily amount of muscular activity might prob- 
ably be on the average about equivalent to that of a man at 
light muscular work. No attempt was made, however, to pres- 
cribe a uniform amount of exercise for each subject from day 
today. The men simply pursued their ordinary course of life 
except as regards diet.
