BULLETIN 505, U. S. DEPARTMENT OF AGRICULTURE. 
experiments intended to compare the digestibilities of several of the 
more common vegetable fats, concluding that all vegetable fats are 
equally veil digested. 
The experiments made at this time coneern only the actual per- 
centage of fat available to the body, though it might be possible at 
the same time to notice approximately how much of the oil can be 
used without producing a laxative effect or other physiological dis- 
turbances. Six subjects assisted in the work, and the same methods 
ware used which hitherto have proved entirely satisfactory. The 
data describing the results of the 12 test periods are as follows:
