 TABLE I. ENERGY VALUES OF MILKS * 8 



* In computing these values, 977 grams have been used as the weight of one quart 

 of milk. This is the weight of a quart of milk of specific gravity 1.0323, or nearly 

 the average specific gravity of milk. The use of the minimum or maximum limits 

 of specific gravity of normal milk (1.029-1.065) would change the values so slightly 

 as to be negligible in so far as the purpose of this circular is concerned. 



The figures given in Table I show that accompanying an 

 increase of fat from 3 per cent to 7 per cent, there is a cor- 

 responding increase in net calorific value from 546.87 to
