Aeroplane for Army Use, Invisible in the Air readily let light rays through. Thusthe machine, aside from its skeletonframework is practically invisible andthe latter quickly Eades from view in the heights. The Quest for Better Light Announcement was made in the December issue of the new nitrogen-filled lamp,which will produce twice as much light, per unit of electrical energy, as any pre-vious lamp. This development in lighting was made at the research laboratory ofthe General Electric Company, under the guidance of Dr. Irving Langmuir. Theauthor of this article,- also an investigator in this institution, and one having to dowith many of the experiments leading up to the momentous discovery, has con-sented to tell of some of the very interesting things which go on there in the questfor better light.—Editorial Note.
