METABOLISM EXPERIMENT NO. 14. 
Subject. — E. O., who served as the subject in experiments Nos. 11 
and 13 here reported. His weight without clothing was about 64 kilo- 
grams (141 pounds). It will be noticed that he had lost about 6 kilo- 
grams in weight between the last experiment and this one. During 
the intervening time he had a severe cold.
