Byconducting the gas generatiou under reduced pressure, it isclaimed that the gas can lie made and fixeil at a muchlower temperature than under ordinary circumstances, andthe formation of obstructive deposit is prevented. The useof an exhauster also makes it easier to admit another gasfor purposes of dilution or otherwise, and a governor, con-sisting of a gas pressure holder suitably connected, alluwathe operation to be carried on with the utmost regularityand uniformity.—A.
