and averaged 4.20 per cent. The amount of casein varied from 
2.25 to 2.98 per cent., and averaged 2.60 per cent. For each 
pound of fat, the amount of casein varied from 0.55 to 0.73 pound, 
and averaged 0.62 pound.

to 2.74 per cent.,and averaged 2.29 per cent. For each pound of 
fat in milk, the casein varied from 0.63 to 0.8L pound, and
