earlier announcement (ANAL. CHEM.,
A course in atmospheric sample analysis to be sponsored by the U. S. Public Health Service will be given at the Robert A. Taft Sanitary Engineer ing Center in Cincinnati, January 13 to 24. The course, designed for pro fessional people with training in chem istry or related sciences, deals with laboratory analysis of particulate and gaseous samples. It includes lectures and discussions. Specific pollutants are treated further by laboratory exercise. Particulates, crystalline minerals, me tallic elements, alkali metals, gases, and vapors will be analyzed by instrumental methods. There are no registration or tuition charges for the course. Further in formation and a detailed agenda may be obtained from: Chief, Air Pollution Training, Training Program, Robert A. Taft Sanitary Engineering Center, 4676 Columbia Parkway, Cincinnati 26, Ohio.

June, page 40A) gave the date as January 28 to 31. The symposium, to be held at Loui siana State University, Baton Rouge, will feature lectures on three topics not too well known in the United States. These are: absorption flame spectro photometry by A. Walsh, of Melbourne, Australia; ring oven techniques by Herbert Weisz of Vienna ; and photo titrimetry by Clark E. Bricker of Princeton University. Additional details appear in the earlier article.
Electroanalytical techniques, ion ex change separations, x-ray, infrared, ab sorption, and ultraviolet spectroscopy and infrared and gas chromatography are among the topics scheduled at the ninth Pittsburgh Conference on Ana lytical Chemistry and Applied Spec troscopy, to be held at the PennSheraton Hotel, Pittsburgh, March 3 to 7. The Exposition of Modern Analyti cal Equipment, held in conjunction with the conference, has been expanded. New developments in instruments and equipment for the analyst will be shown.
Instrument Society of America's chemical and petroleum industry sym posium will be held at the Hotel DuPont in Wilmington, Del. on Feb. 3 and 4. Twelve technical papers are planned for the sessions, dealing with recent developments in process stream analyzers and maintenance of such in struments, analog computation in proc ess control problems, contracted instru ment maintenance, and other similar topics.
