160th National ACS Meeting Chicago, III. September 13 to 18 The Analytical Chemistry Divi­ sion has scheduled technical ses­ sions at the fall Chicago meeting from Monday, Sept. 14 through Fri­ day morning, Sept. 18. W i t h the ex­ ception of the Fisher Award Sym­ posium and sessions of general pa­ pers, all planned symposia are being held jointly with other divisions. Sessions on analytical calorimetry will be held jointly with the Divi­ sion of Polymer Chemistry; direct vapor analysis with the Division of Agricultural and Food Chemistry; liquid chromatography with the D i ­ vision of Petroleum Chemistry, Inc.; teaching of analytical chem­ istry with the Division of Chemical Education ; photoelectron spec­ troscopy with the Division of P h y s ­ ical Chemistry; laboratory automa­ tion and direct recording of infor­ mation for future retrieval with the Division of Chemical Literature; chemistry of organic matter in natural waters with the Division of Water, Air, and Waste Chemistry; and ion exchange with the Division of Colloid and Surface Chemistry. In addition to the technical ses­ sions, there will be a chemical ex­ position at the Conrad Hilton, Sept. 15 to 18, with 240 booths. Specially scheduled ACS short courses will deal with chemical microscopy, gas chromatography, column selection in gas chromatography, and inter­ mediate gas chromatography. To register or for more information on the short courses write to Education Office, American Chemical Society, 1155 Sixteenth St., N.W., Washing­ ton, D . C. 20036 or call 202-7373337, ext. 258. The full program for the Ameri­ can Chemical Society meeting ap­ pears in the August 10 issue of Chem. Eng. Neivs. Further details on Analytical Division activities

are available from the Division Sec­ retary-Treasurer, Richard S. Juvet, Jr., Dcpt. of Chemistry, Arizona State University, Tempe, Ariz. 85281. PROGRAM DIVISION OF ANALYTICAL CHEMISTRY S. Siggia, Chairman, R. S. Juvet, Jr., Secretary

You can cram 90 tubes into 108 square inches. But if you don't have to, you can select other lift­ off reels holding up to 180 tubes. And you don't have to put the controller under the drive base. If you are in a cramped cold room, you can put it on a shelf under the work table, or even outside.

ISCO has othercircularand linear fraction collectors, flow monitors, and many more instruments for biochemical research. For more information, write for brochure FC31.

"This continuing series provides a valuable reference both to the re­ searcher engaged in x-ray analysis and to the beginner who needs to develop competence quickly." —Analytical Chemistry This volume is the latest in an out­ standing series that provides a forum for international exchange on current studies in the nature, behavior, and application of electro­ magnetic radiation. Indicating the current activity and breadth of the field of x-ray analysis, this volume not only presents fundamental re­ search, but covers the latest novel applications of established tech­ niques involving low-energy x-rays. 681 PAGES S B N 306-38113-3

TABLES OF SPECTRAL LINES Third Edition, Revised and Enlarged Compiled by A. N. Zaidel', V. K. Prokof'ev, S. M. Raiskii, V. A. Slavnyi, and E. Ya. Shreider Translated from Russian

This book, however, is specifically designed for every-day use. Its three parts contain virtually all the reference material that working spectroscopists—particularly, spectrochemical analysts and atomic emission spectroscopists—might re­ quire. Itpresentsan extensive set of references, arranged by element, for those investigators who desire more detailed information. Part I pre­ sents approximately 52,000 lines in order of decreasing wavelength. Part II lists about 38,000 lines accord­ ing to element. Part III contains important auxiliary reference mate­ rial. 782 PAGES S B N 306-65151-3
