The number of pounds of butter, 10,983, divided by 9531, 

 the number of pounds of fat, gives 1.152 pounds of butter 

 from each pound of fat. The column headed 1.15 in the 

 table is nearest to this ratio, and will therefore give the 

 butter obtained from 100 lbs. of milk containing different 

 per cents of fat. 



If a patron delivered 9420 lbs. of milk containing 3.2 per 

 cent of fat during the period considered, his milk would 

 have contained 301.44 lbs. of fat, which at 28.8 cents per 

 pound would have amounted to $86.81. It would have 

 made 301.44 X 1.152 = 347.26 lbs. of butter. In the column 

 headed 1.15 in the table, opposite 3.2 per cent of fat, we 

 find 3.68, which is the number of pounds of fat from 100 

 lbs. of this patron's milk. The error from the use of the 

 table in this way will never amount to more than i ounce 

 per 100 lbs. of milk.
