at Slaqelse, but the milk at the last establishment was 

 all taken from one stable adjoining the creamery, and 

 was consequently of uniform character as to quality. 



These experiments show that there is an important ad- 

 vantage obtained in the quantity of butter by heating 

 such milk to 10-i degrees Fahrenheit before setting 

 aside to cream. This will be especially the case where 

 the milk before or during transportation is reduced to a 

 low temperature, as in cold weather, and again in hot 

 weather, when it is found necessary to cool the milk at 

 the farm before transportation, in order that it may 

 arrive at the creamery in good condition. No loss from 

 cooling will be sustained if the milk, before setting, is 

 raised to a temperature of 104 degrees Fahrenheit. 



A singular peculiarity was observed in the cream from 

 the milk which had been cooled, drive?!, and again heated 

 to 86 degrees Falirenlieit. While by exact skimming the 

 quantity of cream from the three samples was nearly the 

 same (namely, sixteen per cent), it was in this sample 

 eighteen per cent, and the time required for churning 

 had been almost twice as long for the samples heated to 

 86 degrees as for those heated to 104 degrees Fahrenheit; 

 and this was the case whether the cream was churned 

 sweet or sour. Again, the cream from the sample of milk 

 heated to 86 degrees, though it weighed most, did not 

 appear the thinnest, yielded less butter than that from 

 the milk heated to 104 degrees Fahrenheit, and the 

 cream of this sample also appeared thin. 



Some remarkable observations were made in churning 

 siveet cream. By the centrifuge experiments it was no- 

 ticed that when the centrifuge crenm, after its separation 

 from the milk, was from 58.1 to 60 degrees Fahrenlieit, 

 and directly afterwards was cooled to the usual churning 

 temperature of 57.2 degrees, and was then churned, the 

 yield of butter was about seventeen per cent less than 

 when the cream was first cooled to 33.8 degrees, and then
