2584. These Stills are made entirely of copper, and consist of two parts, 
the base or boiler, and condenser. They can be used on any kind of stove or 
burner. The condenser is set in the base, which is to be filled with water and put 
on a stove. The steam generated passes up through the central tube to the top of 
the condenser and is there distributed into the condensing tubes. These tubes are 
double, and the steam which is forced through the small space next to the air 
between the. outer and inner tubes is rapidly condensed and accumulates in 
the drum at the bottom of the tubes and runs off through the drip-pipe into a 
bottle or other container. One quart of distilled water can be produced every 
thirty to forty-five minutes, according to the temperature of the room. 
They are made with two kinds of bases. The Rochester, or plain base, is 
recommended if the apparatus is to be used for reclaiming alcohol, or other pur- 
poses than water. If to be used for water only, the Arnold quick steaming base 
is advised, because it is more rapid. 
No running water or other artificial means for condensing is required.
