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 relished 
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
