 scope, it appears to be filled with myriads of little round glob 

 ules, which float in the watery substance, and which rise to the 

 surface in the form of cream, the largest particles rising first, 

 and being the richest in butter. These globules are the butter 

 particles, surrounded with a cheesy film, and the object of 

 churning is to break this film, or coating, and to disengage the
