An eye that remained inflamed subsequent to a cataract extraction and which proved resistant to the usual forms of therapy was treated by radiation with light derived from a composite electrode of tungsten and titanium. The marked and unexpected improvement in the eye served as a stimulus for the authors to investigate various properties of the light derived from this source, and their experimental work and conclusions are set forth in this little volume.

Relying on photographic methods they studied the penetrating power of both luminous and ultraviolet rays, analyzed the light given off by the tungsten-titanium electrode and compared the penetrating power of light derived from this source with that of light derived from other sources. They established the penetrating power of ultraviolet rays and conclude that titanium is a valuable addition to tungsten as a source of such penetrating power. The bactericidal effects of the radiation were also examined,
