(1) In June 16 herds produced more casein in proportion to 

 fat than in May by amounts varying from 0.01 to O.OG pound of

 in proportion to fat by amounts varying from 0.01 to 0.13 pound

 The general average icas a decrease of 0.02 pound of casein for each

 Four herds remained the same as in June. The general average
