 force to cause a fur- 

 ther and more com- 

 plete separation of

 Babcock test sul- 

 phuric acid only is 

 used, but hot water 

 is added to the sample, after subjecting it to cen- 

 trifugal force, in order to float the fat into the 

 graduated neck of the bottle.

 first given to the 

 public in July, 1890.
