A rather incomplete report of the work of Dershem on the X-ray spectrum of tungsten has appeared in the proceedings of the Iowa Academy of Science, A complete report is to be found in the Physical Review of June, 1918, where he finds this spectrum to contain 19 lines in the L region. Further experiments have been carried on using the same apparatus and method as used by Dershem, but increasing the time of exposure, with the result that six new lines have been discovered.
