The summary of Table 15 shows a remarkable coincidence 

 between butter fat delivered, butter fat churned, and butter fat 

 recovered in the butter. The average amount of butter fat 

 received each day was, according to the patron's test, 899.79 

 pounds; test before starter was added 893.2 pounds and test i 

 after starter was added 892.71 pounds. The average butter 

 fat recovered was, according to churn samples 883.43 and tub 

 sample 892.57 pounds. The data are so arranged that each day's 

 comparison is complete in itself, except that on June 30, the 

 1,256.4 pounds of butter fat were divided into two comparisons. 

 The total butter made in this experiment was 21,523 pounds. 

 An average for each day of 1,076.15 pounds. The average per 

 cent butter fat in churn and tub samples were 82.09 and 82.94 

 respectively. Difference 0.83 per cent.
