(Acidity not over 0.18 per cent.) 



Dirt IS 



(No dirt in suspension.)

(No signs of abnormal ferments.) 

 Flavor 25 



(Entire freedom from abnormal odor and taste.) 



In each milk, the score is diminished in the case of 

 each quality if the milk shows any imperfections. This 

 system will be found effective in application, If the
