from the butter, on the same principle that the centrifugal 
machine used in sugar refining expels the water from sugar. 
The machine (the invention by M. Baquet) consists of a per- 
forated cylinder (a), mounted on a vertical spindle, and driven 
by means of friction cones at a suitable speed. The sectional 
illustration (Fig. 12) shows clearly the details of the machine. 
Two sizes of these machines were exhibited ; one meant for 
large butter factories, and driven by power, capable of treating

16 lbs. of butter at a time (of which the illustration is a section); 
the other for small dairies, worked by hand, taking 8 lbs. of 
butter. The butter, after leaving the churn, and while in the 
granular state, is placed in a thin canvas bag, fitting inside 
the perforated cylinder, which is made to revolve at about J800 
revolutions per minute ; the centrifugal force being then suffi- 
cient to drive the butter-milk outwards through the granular 
particles of the butter into the space between the perforated
