r I iHE Xorelco Reporter, a bimonthly -*- house organ published by the North American Philips Co., Mount Vernon, Ν. Υ., has just published a special 75page issue for March to September de voted to x-ray spectroscopy which many of you on their mailing list have already received. This one, devoted to a rela tive^' new field, while popularizing their own equipment, is sufficiently broad in its scope of original and reprinted papers to warrant special mention so that all those interested in the application of these meth ods to analytical problems will want to write to get a copy (See "Books," page 84A, for details). We remember the service other manu facturers have rendered in the past to special fields such as polarography, where bibliographies were published which were a real help to workers in the field. This particular issue is dedicated to Professor Marine Siegbahn, University of Stockholm, Nobel Prize Winner in 1924, and recipient of the Rumford Medal of the Royal Society, London, 1940, for pioneering work in high-pre cision x-ray spectroscopy and its ap plications. For this special issue, he has written an interesting short retro spective survey on the subject. William Parrish of the Philips Laboratories has an excellent review on x-ray spectrochemical analysis. Marian Mack, also of Philips, has compiled a useful bibliography of 157 titles, and states: "This bibliogra phy shows that most of the publications dealing with t h e x-ray spectrochemical method have appeared during the past few
