159th National ACS Meeting Houston, Tex. Feb. 22-27 he 159th National American Chemical Society Meeting will be held Feb. 22 to 27, 1970, in Houston, Tex. In addition to general papers and a symposiüm on recent adin thermal analysis, the Analytical Chemistry Divances vision has scheduled two award symposia and joint symposia with the Divisions of Cellulose, Wood, and Fiber Chemistry and Petroleum and with the Division of Nuclear Chemistry and Technology. A special Award Symposium in Gel Permeation Chromatography will honor J. F. Johnson of the University of Connecticut and an Award Symposium in Chemical Instrumentation will honor N. D. Coggeshall of Gulf Research and Development. Symposia on gel permeation chromatography will be held jointly with the Divisions of Cellulose, Wood, and Fiber Chemistry and Petroleum Chemistry, Inc., and symposia on modern techniques of neutron activation analysis and nuclear methods in the field of exploration for natural resources will be held jointly with the Division of Nuclear Chemistry and Technology. Most of the technical sessions of the Division will be held at the Albert Thomas Convention and Exhibit Center which will also house the ACS Chemical Exposition where 157 booths will display the latest in chemicals, equipment, instruments, publications, and services. The ACS is also presenting two short courses during the meeting: Feb. 20 to 22, a on on polymer chemistry and Feb. 26 to 27, a course course intermediate spectroscopy. The detailed technical program of the Analytical Chemistry Division is given below. Complete information on the National Meeting appears in the Jan. 26 issue of Chem. Eng. News. Further details on Analytical Division activities are available from Richard S. Juvet, Jr., Secretary-Treasurer, Department of Chemistry and Chemical Engineering, University of Illinois, Urbana, 111. 61801.
