ASSOCIATIONS

ASSOCIATIONS Southeastern Regional Meeting The 21st Annual Southeastern Re­ gional Meeting of ACS will be held in Richmond, Va., Nov. 5-8. Sponsor is the ACS Virginia Section. A program of about 400 papers will be presented, with about 50 of them in symposiums on extraterrestrial chemistry, auto­ mated analysis, homogeneous catalysis, inorganic fibers, inorganic mass spec­ troscopy, photochemistry, molecular spectroscopy, drug design, integrated laboratory curriculum, hallucinogenic drugs, antimalarials, and fibers and films. General papers in 34 sessions cover analytical, biological, inorganic, medicinal, organic, physical, polymer, radio and nuclear chemistry and chem­ ical education. Many undergraduate papers have been integrated into the regular divisions and there is also one full session devoted entirely to under­ graduate papers. Harold M. McNair, associate profes­ sor of chemistry at Virginia Polytech­ nic Institute, will present an ACS Short Course on Column Selection in Gas Chromatography on Nov. 8. For further details, write Education Of­ fice, ACS, 1155-16th St., N.W., Wash­ ington, D.C. 20036. Registration for the meeting begins at 6 P.M. Tuesday, Nov. 4, in the John Marshall Hotel, headquarters for all sessions and instrument displays. Special events scheduled include a mixer sponsored by Phipps & Bird, Inc., Wednesday evening; a dinner theater featuring "Don't Drink the Water" on Thursday evening at Swift Creek Mill Playhouse; and the South­ ern Chemist Award to be presented Friday at a luncheon, with Dr. Mil­ ton Harris as speaker. Local section officers will meet at luncheon Wednes­ day, Nov. 5. Virginia Johnson of Philip Morris, U.S.A., will welcome all ladies at the Ladies' Hospitality Suite and has ar­ ranged a program which includes his­ toric and shopping tours, a fashion show, and demonstrations on party foods and Christmas decorations. Dr. Helmut Wakeham of Philip Morris is general chairman of the meeting. Dr. Preston H. Leake of American Tobacco Co. is program chairman and B. S. Holt of Universal Leaf Tobacco Co., exhibits chairman. Registration forms will be mailed to all ACS members in the Southeastern region early this month, or they may be obtained along with further informa­ tion on the meeting from Dr. R. G. Bass, Dept. of Chemistry, Virginia Commonwealth University, 901 West Franklin St., Richmond, Va. 23220. Housing should be arranged directly through the John Marshall Hotel, 6th & Franklin Sts., Richmond, Va. 23219. Abstracts of papers presented at the meeting will be given to registrants and will be available for $3.00 to other ACS members who wish to order them from Dr. Bass (checks payable to Southeastern Regional Meeting, ACS).

Take Engelhard Crucibles for example: Standard form crucibles—have an Engelhard exclusive... All are hand hammered minimizing fatigue and stress cracking. Polygon form—have flat gripping surfaces for more secure handling... have built-in pouring spouts and flat bottoms. Trilay® construction- is a new platinum metal composite material for crucibles. It inhibits formation of large crystals- crucibles last longer and are stiffer and easier to clean. Platinum 3!4% Rhodium- recommended for high temperature fusions and ignitions. Pure Iridium and Pure Rhodium Crucibles —suggested for melting and other high temperature applications where platinum or platinum alloys cannot be used. Other Engelhard platinum implements and equipment for the laboratory include: dishes, beakers, trays, tongs, and special apparatus to order.

The program will be devoted to two divisions: organic chemistry and mac- romolecules. Each will have a number of symposiums, and in addition, five joint symposiums are planned. Con­ tributed papers in the general fields will also be accepted. Official lan­ guage will be English; papers may be presented in any language, but the organizing committee recommends that speakers use one widely under­ stood, since no arrangements will be made for simultaneous translation. Interpreters will be available at the congress to assist participants. There will be an international ex­ position of chemical equipment, in­ struments, and publications. The first circular, giving more de­ tails of the congress, is available from A. T. Winstead, c/o ACS, 1155-16th St., N.W., Washington, D.C. 20036.

AWARDS A Gold Medal in honor of Dr. C. H. Bailey (1887-1968) has been estab­ lished by International Association for Cereal Chemistry. It will be given infrequently to persons selected by the IACC executive committee for dis­ tinguished contributions to cereal technology and international coopera­ tion and understanding. The first medal will be presented at the 5th World Cereal and Bread Congress at Dresden, Germany, in May 1970. MEN & MOLECULES . . . released for broadcast after Oct. 10 is titled The Voyage of Glomar Challenger and features Dr. Alfred Fischer of Princeton University and Dr. Melvin Peter­ son of Scripps Institution of Oceanography. See "Men and Molecules" list­ ings beginning on page 54 of C&EN, Sept. 8 for stations broad­ casting in your area. Each week C&EN announces here the "Men and Molecules" program to be re­ leased the following Friday.
