experiments intended to compare the digestibilities of several of the 

 more common vegetable fats, concluding that all vegetable fats are 

 equally well digested. 



The experiments made at this time concern 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 wdthout producing a laxative effect or other physiological dis- 

 turbances. Six subjects assisted in the work, and the same methods 

 wdre used which hitherto have proved entirely satisfactory. The 

 data describing the results of the 1 2 test periods are as follows :
