Calorie for calorie, separated dried milk is the 

 cheapest food which can be purchased, but of course, 

 it is quite unsuitable for infant feeding unless it is 

 fortified with additional fat to replace the cream 

 which has been abstracted. The cheapest fat that 

 can be employed for this purpose is linseed oil ; 

 linseed oil can be made into a most palatable emul- 

 sion and sold at 35. 8d. per gallon, 1 a price which 

 compares with i6s. per gallon for cream containing 

 the same percentage of fat. 



As far as I am aware the nutritive qualities of 

 an emulsion of linseed oil (Marylebone cream) are 

 in no respect inferior to those of cream, although their 

 constituent fats are not identical. 



For some time past I have experimented with this 

 method of feeding, and I find that infants fed on 

 separated milk reconstituted with water and fortified 

 with Marylebone cream and sugar make just as 

 good progress as do infants fed either on whole 

 cream, desiccated milk, or other more expensive 

 foods. 



Although it is of importance that infants should 

 be supplied with a food which affords a sufficient 

 number of calories per pound of bodyweight, it ii 

 by no means a matter of indifference how the calories 

 are afforded. 



There is an optima ratio for the three main 

 elements of an infant's dietary. I think it safe to 

 conclude that in breast milk these elements are com- 

 bined in a ratio which conforms to the physiological 

 requirements of the average infant. In breast milk
