i68 MILK AND THE PUBLIC HEALTH ch. vm 



Certified Milk, properly modified, which is delivered by a messenger 

 daily. Among 500 (568 accurately) infants, who received no 

 other attention except this help during the year, the mortality is 

 reduced to 2 '7 per cent by this means alone. The mortality in 

 our city among this class is 25 per cent, sometimes 30 per cent. 

 This was accomplished without the work of a visiting nurse to 

 teach infant hygiene in the home, which might leave a doubt in 

 our minds as to the influence of the milk.
