butter. From ihe table oT composition of food materials tlie nutritive 

 iugredieuts wliicli these foods furuisli may be easily calculated. 

 Thus, if oatmeal contains IG.l per cent, of protein and furnishes 1,SG0 

 calories per pound, one-half pound would contain 0.081 pound protein 

 ^0.5 ^ 0.161 = 0.081 pound) and yield 1)80 calories (0.5 ^ 1,800 = 930), 

 and if lamb chops contain IG per cent, protein and furnish 1,130 

 calories per pound, 1^ pounds of lamb chops would furnish 0.24 

 pounds protein (1.5 pounds ^ O.IG = 0.24 pound) and 1,605 calories 

 (1.5 pounds ^ 1,130 = 1,695) calories. The others may be calculated 

 in the same way. 



The assumed quantities of food materials which the four persons 

 would consume in a day, and the calculated protein content and fuel 

 value, would be as follows:

•Coffee and tea in themselves have little or no nutritive value. In the menu, allowance Is 

 made for the milk or cream and the sugar that would ordinarily be added.
