arise under those circumstances. Had the carbon been retained 

 as glycogen the calculated heat production would have been 

 greater (about 4 calories per hour). 



This work confirms in three successive hourly periods the work 

 previously published by Atkinson and Lusk 1 concerning the for- 

 mation of fat from protein under experimental conditions similar 

 to the ones here described. 



The experimental data follow:
