Abstract : Research was continued on a study of infrared sources. A recording spectrophotometer was adapted to serve as an emission rather than as a transmission instrument. A furnace was also constructed for the purpose of heating solid bodies to high temper tures, of the order of 1000 C. The emission spectra of vitreous and ceramic bodies were traced. Samples of cermets, refractory oxides and alloys also were studied. In general, these all behaved more or less like gray bodies. One substance, polycrystalline MgO, showed significantly higher emission at about 12.8 microns than the remaining samples. The problem of using gaseous radiators received preliminary consideration.
