2. Relation betiueen fat-cotUent and conductivity of different 

 samples. — The above figures also indicate, however, that the 

 depression of conductivity due to a given increase of fat-content 

 is not the same for different specimens of milk. To confirm this 

 observation, a number of determinations have been made of the 

 percentage-decrease of conductivity of spun milk due to the 

 addition of 1% of fat. These figures are given in the last column 

 of the following Table.
