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
