On an average the coefficient of digestibility of this fat was low, 

 the corrected value being 94.9 per cent. It will be recalled that the 

 food (blancmange) used as a vehicle for fat in such experiments as 

 this is eaten ad libitum from a weighed amount, provided the amount 

 being such that the subjects would naturally be inclined to eat a 

 quantity which would supply in the neighborhood of 100 grams of 

 fat per day. The fat-carrying blancmange was evidently not rehshed 

 in this test as it was in the others here reported, for the amount 

 eaten was only enough to supply 51 grams of cocoa fat per man per 

 day during the first eight experiments. This quantity did not cause 

 any decided digestive disturbance so far as was noted. The subjects 

 reported a "loss of appetite," but in all other respects considered 

 that their physical condition had been normal. In later tests, ex- 

 periments Nos. 235 to 237, the subjects were urged to eat more of
