Electrolytic Detector.—Adetector widely used in the early stagesof wireless telegraph development inthe United States is the so-calledwhisker point electrolytic, which isparticularly sensitive and uniformlystable in operation. Of late, however,the electrolytic cell has fallen intoalmost complete disuse for commercialworking, even though its reliability isgenerally admitted. From a commer-cial standpoint this may be accounted for
