THE NEW EARTH 



of lean beef, six ounces of boiled ham, three 

 and one-half ounces roast veal or beefsteak, 

 five and one-third ounces of coarse bread, 

 boiled rice, carrots, spinach, radish, or apple ; 

 from four to five hours for nine ounces of 

 smoked tongue, three and one-half ounces 

 of smoked beef, nine ounces of roast goose, 

 five and one-third ounces string beans, or 

 seven ounces of pea porridge. It appears from 

 the investigations that the materials most 

 readily digested are those of soft consistency. 

 The white meat of chickens left the stomach 

 more quickly than the dark meat, or the red 

 meats of other animals. Fresh fish was more 

 easily digested than meats. 



Another important field of development lies 

 in ascertaining the amount of the foods which, 

 under normal conditions, the body assimilates 

 for its own uses. It has been shown by recent 

 investigations that, in an ordinary mixed diet, 

 about ninety-two per cent of the protein, 

 ninety-five of the fats, and ninety-seven of the 

 carbohydrates are retained in the body. There 

 is considerable difference between the amount 

 retained from animal foods and that retained 

 from vegetables. About ninety-seven per cent
