Q : — In regard to the formaldehyde in milk. Does it make 

 any difference to the milk the amount of preservative? 



A : — Well, preservatives of any kind are not allowed in milk

 artificial preservative in the milk. 



I thank you for your attention.

 tion. That is not because the dairymen are dishonest in selling 

 milk below standard, but because there are a great many men 

 engaged in the business who do not know all about what takes 

 place in milk, and do not know^ when they take some cream off
