It will be noted from the above data that the diet as a whole was 

 quite well digested, the values obtained being 79.9 per cent for pro- 

 tein, 94.3 per cent for fat, and 97.6 per cent for carbohydrate. On an 

 average the subjects ate 34 grams of protein, 59 grams of fat, and 400 

 grams of carbohydrate, which supplied 2,270 calories of energy. No 

 attempt was made to ascertain how much cherry -kernel oil could be 

 eaten daily without producing a laxative effect ; but, since one of the 

 subjects ate aproximately 74 grams daily for the three-day period, it 

 seems apparent that the limit of tolerance for this oil is in excess of 

 this amount. 



The high digestibility of cherry-kernel oil, 98 per cent, when con- 

 sidered in connection with the pleasing appearance and flavor of the 

 cold-pressed oil, warrants the belief that when cherry pits are ob- 

 tainable in quantity they should prove a valuable source of a high- 

 grade culinary or table oil. 



MELON-SEED OIL. 



While melon (cantaloup) seeds are not available in this country 

 in sufficient quantities to be of commercial importance as a source of
