 pound of increase when whole milk was fed, 

 and 3.4 cents to make a pound of increase when 

 skim-milk was fed."

 not merely to the fat but to influence the other 

 ingredients. To ascertain the truth of the 

 matter three samples of milk were tested before 

 and after being run through the separator." 

 After concluding the work with the samples 

 the station says: "It is evident from these fig- 

 ures that the milk serum is not influenced by
