Mr. N. Defries. The invention coe in. the substitution of thin pieces 
of metal in the place of coals in fire-grates—which being acted on by 
a small jet of gas, itimcdiaely tebese red-hot, and emit a prodigious 
degree of heat. ‘The flame which is produced by the proper, but very 
simple management of the gas co-operating with the metallic lamine, 
gives the appearance of a brisk and cheerful coal-fire, and can scarcely 
be distinguished from it. ‘The heat can be regulated by turning the 
cock of the gas tube. There is no deposit of soot, no smoke, nor any 
of the annoyances which attend coal-fires, and the gas can, it is said 
be ae instanter, or the fire kept as low as may be con- 
venient.
