and sugar. The proprietary foods contain too much 

 sugar and too little fat. The percentage composition 

 of the mixture prepared from separated milk, Maryle- 

 bone cream and sugar also departs from the standard 

 of breast milk, but without any increase of cost it can 

 be made to conform to any required standard by 

 varying the proportions of the components. I find 

 from experience that 4 per cent, of fat is too high for . 

 the majority of infants, and i '5 per cent, of protein 

 is needlessly low. With a mixture of the above 

 percentage composition I get most excellent results, 

 20 oz. of such a mixture provides 400 calories, enough 

 for an infant 3 months 'of age, weighing 10 Ib. 



TABLE C. PERCENTAGE COMPOSITION OF PROPRIETARY INFANT FOODS 

 AND DRIED MILKS WHEN DILUTED WITH 20 o/,. OF WATER : 20 oz. 



OF EACH PROVIDES 400 CALORIES. 



The formula for preparing 20 oz. of this mixtui 

 is as follows : 



Separated dried milk 

 Marylebone cream 



Sugar 

 Water

Such a mixture is not suitable for all infants, but 

 it is the goal at which we should aim, and by the 

 careful training of the digestive functions by a 

 preliminary course of modified whey mixtures it is a 

 goal which it is very easy to reach.
