Abstract
DR. W. W. COBLENTZ1 is developing the application of the thermocouple to the study of stellar radiation, and is deriving results of considerable interest and value, especially so far as red stars and red variables are concerned. The instrument he uses is not so sensitive as the photo-electric cell which is doing such delicate work in the hands of Guthnick, Stebbins, and others, but it lends itself more readily to the investigation of radiation in the longer wavelengths.
