When filled to 10 atmos-pheres these holders would contain 37G cubic feet, and wouldsupply five four-flame lamps, two vestibule lamps and two bracketlamps, consuming altogether 16 cubic feet an hour, for about 24hours full burning.

By their use it is claimed a steadywhite light is produced and the candle increased morethan three fold. The regulator has to be arranged so asto give an outlet pressure of one pound per square inch. 2667 2667
