• Some of these columns of experiments are made in 

 connection with those set down in the former table, and 

 therefore the figures in the second column do not give 

 anything new; but the figures in the columns for the 

 heating to 86 and 104 degrees Fahrenheit, show that 

 tlie heating to 86 degrees certainly does some good, but 

 not much, while the resistance of the milk for cream- 

 ing, caused by cooling and driving, has been almost en- 

 tirely overcome by heating it to a temperature of 104 de- 

 grees Fahrenheit, and this not only when skimming was 

 done after the milk had set thirty-four hours, but also 

 when skimming was done after ten hours' setting, since 

 the loss of butter for the milk cooled one hour and 

 driven three and a half honrs is decreased from 29.4 per 

 cent for the cold sample to 3.2 per cent for the sample 

 heated to 104 degrees Fahrenheit. 



It will be observed, however, that in the last column 

 of experiments the result at Rosenfeldt, in heating the 

 inilk to 104 degrees Fahrenheit, was not as favorable as
