SEE'S GAS STOVE.

This stove consists of two or more superposed pipes provided with

radiators. A gas burner is placed at the entrance of either the upper or

lower pipe, according to circumstances. The products of combustion are

discharged through a pipe of small diameter, which may be readily

inserted into an already existing chimney or be hidden behind the

wainscoting. The heat furnished by the gas flame is so well absorbed by

radiation from the radiator rings that the gases, on making their exit,

have no longer a temperature of more than from 35 to 40 degrees.

The apparatus, which is simple, compact, and cheap, is surrounded on all

sides with an ornamented sheet iron casing. Being entirely of cast iron,

it will last for a long time. The joints, being of asbestos, are

absolutely tight, so as to prevent the escape of bad odors. The water

due to the condensation of the gases is led through a small pipe out of

doors or into a vessel from whence it may evaporate anew, so as not to

change the hygrometric state of the air. The consumption of gas is very

small, it taking but 250 liters per hour to heat a room of 80 cubic

meters to a temperature of 18° C.--_Revue Industrielle_.
