The latter are low ob- long chambers, measuring about 12 feet in length, 4 feet in breadth and 2 feet in ing up the first pot passes through the passage at the top through the second chamber and regenerator into the chimney until the proper heat is attained. The current of air and gas is then reversed, the valve, a single fourway-cock, commandin both passages by a single movement, onl the heating of the second chamber com- mences; the current of spent flame, which at first is notably cooler than the pre- viously heated pot, is passed over the lat- ter until their temperatures are about equalized, when the finished heat is re- moved and a new pot is inserted.
