and for vegetables 80 per cent, of the average amounts spent by the 

 ten subjects for such materials. It is to ])e noticed that he used consid- 

 erable sugar (for which no charge is made) and got along practically 

 without beverages (tea, coffee, and cocoa), thereby effecting a consid- 

 erable saving. As regards dairy products, the quantity of protein 

 bought for 1 cent is about 35 per cent higher than the average for the 

 ten men, and that of energy al)Out equal to the average. 



At the end of the investigation Subject E had gained 3.7 pounds in 

 weight and showed a corresponding slight increase in his anthropo- 

 metric measurements. No change in his general physical condition 

 was noted. 



In the examinations at the end of the academic year he passed in 

 all his studies with an average grade a little below B, a very credit- 

 able performance considering the fact that he carried seven courses. 



In general, it may be said that Subject E accomplished a satisfac- 

 tory year's work, chiefly intellectual in nature, on a diet which aver- 

 aged for the three test periods almost exactly the amounts of protein 

 and energy required by a conmionly accepted standard for a man of 

 sedentary occupation, and maintained his general health and physical 

 condition.

Subject F was 25 years old, 5 feet 3.8 inches in height, and weighed

 to sleep. He did no outside work. During the fall and winter periods

 played handball three-fourths to H hours per day for seven days. 



Subject F was a second-year student in the graduate school, and car-
