 with the problems of technical dairying. 



Every branch of production has, in its expanding 

 development, been forced to acknowledge the sound- 

 ness of the principle of division of labor, yet if we 

 recapitulate what has been said about the necessary 

 supervision of the physical condition of the animals 

 furnishing the milk, about the necessity of sterilizing 

 it immediately after drawing, and about the pollution 

 it is exposed to by unclean handling before consump- 

 tion, we will reach the conclusion that the production 

 of infants' milk is an exception .to this rule of divi- 

 sion of labor, and that no guarantee of pureness and 

 absolute healthfulness can be expected or given unless 

 the entire process of production, from the cow's 

 mouth to the baby's bottle, is covered by one and the 

 same responsibility, and controlled in every stage of 

 handling by those only competent to do so : the phy- 

 sicians and the veterinarian of the neighborhood. 



We have seen that the purpose of sterilizing milk 

 is not only to give it keeping qualities by the deaden- 

 ing of all germs, also those of disease, but by this act

painful conviction that not infrequently there lurks
