The results embodied in the preceding table can be summarized 

 as follows: 



Tablk Showing Pounds of Fat in 100 Pounds of Milk. 



May 3 . 58 pounds. 



June y . 59 pounds. 



July 3.71 pounds. 



August 4 . 04 pounds. 



September 3.97 pounds. 



October 4.20 pounds. 



Averaging the amount of fat contained in the milk of all the 

 different herds, we see that the fat in 100 pounds of milk was 

 about the same in May and June, that the amount increased 

 during July and August, fell slightly in September and then 

 increased in October. 



Giving a more detailed summary, we find — 



(1) In June 24 herds produced more fat in 100 pounds of milk 

 than in May, the amount of increase varying from 0.01 to 0.53 

 pound ; while 26 herds produced less fat than in May by amounts 

 varying from 0.02 to 0.70 pounds. The general average urns a 

 slight increase of fat amounting to 0.01 pound of fat for 100 pounds 

 of milk. 



(2) In July 38 herds produced more fat in 100 pounds of milk 

 than in June, the amount of increase varying from 0.02 to 0.55 

 pound; while 10 herds produced less fat than in June by amounts 

 varying from 0.02 to 0.52 pound. Two herds showed neither de- 

 crease nor increase. The general average of all results ivas an 

 increase amounting to 0.12 pound of fat for 100 pounds of milk. 



(3) In August 45 herds produced more fat in 100 pounds of 

 milk than in July, the amount of increase varying from 0.03 to 

 0.78 pound; while only 3 herds produced less fat than in July by 

 amounts varying from 0.05 to 0.28 pounds. The general average 

 was an increase of 0.33 pound of fat for 100 pounds of milk. 



(4) In September 16 herds produced more fat in 100 pounds of 

 milk than in August, the amount of increase varying from 0.02 to 

 0.30 pound; while 28 herds produced less fat than in August by 

 amounts varying from 0.02 to 0.78 pound. Three herds showed
