Butter : 1,000 grammes contain— fI?^ ■■ *■ gJ'^^nimes gross, equal to 9-7 grammes digestible. Carbohydrate 15 ',; 7g;o ,. .-. Food value is (9.7X 5)+ (769X 3)+ I4-7X i) =2,371. Potatoes : 1,000 grammes contain— Protein .. . .20-0 grammes gross, equal to i6-8 grammes digestible. Carbohydrate i9S'o \\ 185-2 .-. Food value is (i6-8 x 5)+(i-4x 3)+(i8s-2x i) =273. Dried peas : 1,000 grammes contain— Protein.. .. 238 grammes gross, equal to 185-0 grammes digestible. • • ■ • 18 „ l6'2 Carbohydrate.. 600 „ 570-0 .-. Food value is (185x 5)+(i6-2x 3)+(S70X i) =1,544. Boiled cabbage : 1,000 grammes contain— Protem .. .. 6 grammes gross, equal to 5-00 grammes digestible. .. ..

Carbohydrate .. 126 „ „ 118-70 .-. Food value is (3-36X S)+(4-SX 3)+ (118-7X i)=i49. Calculation of the Constituents in One Ounce of Food : Let the number of grammes per cent, be divided by 3-52, the dividend will represent the grammes per ounce—^.g., one ounce of cooked beef contains 28-5 divided by 3-52= 8-1 grammes of protein, and 41-25 divided by 3-52= ii-6 grammes of fat.
