This experimentshows that the loss of unieuovei'ed buiter-luL — wiiiuh was left in 

 the skim-milk — was 11'48 per cent greater, when the setting of milk in deep-setting 

 pails in ice water was delayed one hour, than it was when the milk was set 

 immediately. 



Experiment in Beep-setting of iWJkfor 11 Hours vs. 22 Hours. 



This test was continued for six days — from 12th August to 18th August — and 

 comprised six settings of morning milk and six settings of evening milk in each 

 case. The milk was mixed herd milk, and was set immediately after it reached the 

 dairy building in deep-setting pails, in ice water of a temperature of 38° to 40° 

 Fahr. 



Table III shows the average results from the 24 settings of milk.
