examinations in all his studies with an average grade of B. When we 

 remember that he carried six courses and did outside clerical work in 

 addition to his college work, this is a very creditable showing. 



It appears, then, that this subject, 16 years old at the beginning of 

 the investigation, performed his college work with credit and gained 

 steadily in bodily weight throughout the year without the slightest 

 sign of deterioration in his general physical condition on a diet which 

 furnished on an average 63.5 grams of digestible protein and 2,506 

 calories of available energy per diem.

Subject K was 22 years old, 5 feet 6.8 inches in height, and weighed 

 151 pounds. He alone of all the men studied seemed thoroughly 

 strong and robust physically, and such a man as one would consider 

 fit to take an active part in college athletics. His anthropometric 

 measurements showed him to be generall}^ above the normal for men 

 of his age and he was classed on examination as well developed and 

 well nourished. 



He was a senior in the college and devoted himself to the study of 

 Greek and classical philology, carrying four and one-half advanced 

 courses. On an average he spent daily 10 to Hi hours on college 

 work, including lectures, reading, etc., and slept 6f to 7 hours. His 

 only physical exercise for the entire three periods was a walk of an 

 hour, but during the first period he served as a waiter at Randall Hall 

 li to 3 hours daily for 16 days, during the second period 1 to 4 hours 

 daily for 17 days, and during the third period 2i to 4i hours daily 

 for the entire three weeks. From this it appears that his working 

 day covered 12 to 14 hours.
