Admission to the exposition is complimentary. While planning your schedule in Washington, reserve some time to visit the ACS National Exposition. In addition to functioning as a showcase for the most up-to-date scientific products and services, the exposition also serves as a valuable source of continuing education for national meeting attendees. New this year: Several ACS divisions will present poster sessions within the exposition hall.

Located in Hall B of the Washington Convention Center, the exposition will be open Monday, Aug. 24, 5 to 7:30 PM, in conjunction with Sci-Mix, which will be held on the exposition floor. Additional hours will be Tuesday and Wednesday, Aug. 25 and 26, from 9 AM to 5 PM, and Thursday, Aug. 27, from 9 AM to noon. A full restaurant and lounge on the exhibit floor offers an economical and convenient place to eat, or just sit and converse with fellow attendees. Free coffee is available in the exhibit hall every morning.

The exposition will consist of about 400 booths, representing about 220 companies and organizations displaying everything from instruments and books to computer hardware and software. Also on display will be chromatographic and lab equipment, furniture, and safety equipment. Each exhibiting organization will have expert personnel on hand to give demonstrations, answer questions, and discuss your needs and interests. In addition to the comprehensive display of products and services of interest to the scientific community, there will be giveaways, several drawings for prizes, and a free ACS souvenir for all visitors to the exposition.

Admission Requirements. Although admission to the exposition is complimentary, a badge is required to enter the exhibit hall. Badges will be mailed to all preregis-trants; on-site registrants may obtain a badge at the main registration area in the Washington Convention Center.

Exposition Workshops. A series of exposition workshops will be conducted in Washington and will cover a variety of topics. Attendance will be limited and restricted to workshop registrants (see pre-registration form on page 109). Workshops will be held Monday through Wednesday,

W A S H I N G T O N , O.C Aug. 24-26, in the Washington Convention Center. See pages 108 and 109 for a complete workshop schedule.

Commemorative Postal Cachet/Postal Substation. The 15th in a series of philatelic covers featuring ACS presidents will be available for sale at the Beckman Center for the History of Chemistry booth (758). Sponsored by the ACS Division of the History of Chemistry, this cachet will feature Edgar Fahs Smith, ACS president in 1895 and 1921-22. A temporary postal station will be available in the exposition area, and a special ACS postal cancellation commemorating the 204th national meeting will be available for use on the commemorative envelope.
