DETAILS OF DIGESTION EXPERIMENT NO. 51. 



This study was preliminary to metabolism experiment No. 12. with the same kinds and 

 aim Hints of the different food materials. The subject, E. O., was engaged in his usual laboratory 

 work, but in addition took considerable muscular exercise on the bicycle and otherwise, in order 

 to make the conditions of muscular activity not greatly different from those in the following

 The subject weighed, without clothing, 70.5 kilograms (155.4 pounds) at the beginning and 70.1 

 kilograms (154.5 pounds) at the end of the study.
