DISTILLATION.

The portable furaace(1) is most excellent for boilers oi from 5 to 10 gallons,and may be used as a heating or cook ing stove for families, as well as for the purjioses of distil lation. Coal can be filled in without moving the boiler, it ha-ving a good draught of air, and being laid out with fire bricks, with a fall-grate for extinguishing the coal after using. The above can be obtained, ready-made, of J. Murphy,at No.256 Water sti'eet, complete for §5. The conauriit, or boiler (2), belonging to the furnace, contains 10 gallons of liquid, and is formed of tinned cop- ,per—the smaller part of the bottom standing on the fire bricks, while the upper bottom covers the top of the fur nace. This construction enables the first heat of the coal to give its whole strength on the under bottom, and rising up by the door, continues around the boiler, between the top and the brick-work, and in the stove-jiipe. By this process, time and coal are both saved. /i=i\

2. Distillation Consists essentially in converting a liquid into vapor in a close vessel, by means of heat, and then conveying the vapor into another cool vessel, where it is condensed agaiu into a liquid. To accomplish this, the liquids are placed in the boiler (2), and when heat is applied to the boiler, spirit begins to rise in vapor at 116° (degrees), and water is converted into vapor at 212° (degrees). These vapors pass firom th«
