In the work experiments the supply was generally. not quite 
_ sufficient for maintenance and in some of the experiments, 
¥ especially those with J. C. W., it fell considerably short of 
- meeting the demand. The drafts upon body material as shown 
; in Table 21 above indicate the extent to which the actual de- 
mand exceeded the supply in the food. 
r i 
The supply of protein in the earlier experiments with E. O. 
and O. F. T.., and indeed in the rest experiments with A. W.S. 
2 and J.C. W. also, was intended to approach more or less nearly 
to the quantity to which the subjects were ordinarily accus- 
 tomed, though in every case it was intended to be small rather
