A NEW GAS.

An experiment has recently been made in Loudon of a new gas of high illuminating power, that can be produced at so small a cost, and with bo little difficulty and danger that, if experience does not prove it to possess some highly dangerous or injurious quality it must drive common gas off the fi.-ld as completely as coal gas expelled oil. The Sydney Mommy Herald thus, describes the experiment:—ln a corner of the room there had been fixed a pair of hallows resembling thoa•?. of a church organ, that were being slowly moved by an attendant. By the side of the bellows were two square metal boxes, measuti g between a foot and a foot and a half each way, and connected by pipes with the bellows on one side, and with rows of burners on the other This simple apparatus was all the patentees of the new gas h.d to show, and with it they supplied forty jets in the room with a brilliant light, and undertake to supply the same with very little additional trouble for illuminating half the city of London. In another comer of the rontn the process was still more clearly shown On a small table st' Oil a miniature gasometer, capable of contaiuing one cubic foot of gas In shape it resembled the ordinary cylinders, and its base rested on a second cylinder filled with water. A pipe connected the interior with a glass vessel containing gasogen, the liquid from which the gas is formed, while a second pipe admitted the atmo pheric air into the gasogen holder. Weights being a'tached to the cylinder, caused it to rise slowly, and simultaneously, bv the vacuum thereby produced, the atmospheric air was heard to bubble through the liquid. At the other side, an anrand burner had been attached, from which the gas thus formed was instantly burned with a bright flame, compared with which a coal gas burner placed beside it for comparison, gave a yellowish and less illuminating light. The gasogen is procured by distillation from certain mineral oils, and the facility with which this can be none, and the practically unlimited abundance of the oils renders the gas cheap. Gas so manufactured can be delivered at 2s per 1,000 feet, and 1,000 feet of it burns so slowly, as to be equal to 2,000 of ordinary gas.
