It will be noted from the above data of the digestion experiments 
with black-walnut oil that the total fat of the diet was 94.8 per cent 
digested. On an average 56 grams of black-walnut oil were eaten per 
man per day. If allowance is made for the ether-extracted material 
resulting from the nonfatty portion of the diet, the digestibility of
