The data embodied in the preceding table are summarized as 

 follows: 



Table Showing Pounds of Casein in 100 Pounds of Milk. 



May 5i. 40 pountls. 



June 2.33 pounds. 



July 2 . 20 pounds. 



August 2 . 26 pounds. 



September < 2.47 pounds. 



October 2. 69 pounds. 



Taking a general average of all the results, we see that the 

 amount of casein contained in 100 pounds of milk was less in 

 June than in May, and still less in July, after which there was a 

 more or less rapid increase from month to month. 



The following summary gives greater details: 



(1) In June 11 herds produced more casein in 100 pounds of 

 milk than in May, the amount of increase varying from 0.01 to 

 0.20 pound; while 36 herds produced less casein than in May by 

 amounts varying from 0.01 to 0.50 pound. Three herds showed 

 neither increase nor decrease. The general average of all results 

 shows a decrease of 0.07 pound of casein for 100 pounds of milk. 



(2) In July 7 herds produced more casein in 100 pounds of milk 

 than in June, the amount of increase varying from 0.02 to 0.06 

 pounds; while 43 herds produced less casein than in June by 

 amounts varying from 0.04 to 0.34 pound. The general average 

 was a decrease of 0.13 pound of casein for 100 pounds of milk. 



(3) In August 36 herds produced more casein in 100 pounds of 

 milk than in July by amounts varying from 0.01 to 0.23 pound; 

 while 10 herds produced less casein than in July by amounts 

 varying from 0.01 to 0.11 pound. Two herds showed neither in- 

 crease nor decrease. The general average was an increase of 0.06 

 pound of casein for 100 pounds of milk. 



(4) In September every herd without exception produced more 

 casein in 100 pounds of milk than in August, the amount of in- 

 crease varying from 0.01 to 0.43 pound, and averaging 0.21 pound 

 of casein for 100 pounds of milk. 



(5) In October every herd produced more casein than in Sep- 

 tember by amounts varying from 0.04 to 0.49 pound, the general
