peanuts from which the peanut flour was prepared. The average 

 amount eaten was 55 grams daily; and apparently it was well 

 digested, since the total fat of the diet — principally lard and peanut 

 oil — was 95.5 per cent digested. This compares very favorably with 

 the figures reported for the digestibility of lard ^ and peanut oil ^ as 

 determined in earlier studies.
