MEETINGS lectures and photographing of slides are also prohibited. The unique concept of the conferences was established by Neil Gordon of Johns Hopkins University in 1931. Gordon foresaw the importance of establishing direct communication between scientists while removing the distractions at larger meetings. This year, 12 conferences are of p a r t i c u l a r i n t e r e s t to a n a l y t i c a l chemists: analytical chemistry; analytical pyrolysis: the thermal processes of materials; applied and environmental microbiology; bioanalytical sensors; chemistry and physics of liquids; magnetic resonance; nonlinear optics and lasers; physics and chemistry of laser diagnostics in combustion; reactive polymers—ion exchangers and adsorbents; reverse osmosis, ultrafiltration, and gas separation; three-dimensional electron microscopy of macromolecules; and X-ray physics. Technical programs for these conferences follow. Conferences will be held in both New Hampshire and Rhode Island. For the New Hampshire conferences, the fixed fee for resident participants is $400, which covers registration, room (double occupancy), and meals. The $360 fee for nonresident conferees covers registration and meals. The $310 guest fee includes room and meals only. For conferences held in Rhode Island, fees are $415 for resident participants, $360 for nonresident conferees, and $325 for guests. If registration cards with advance p a y m e n t are p o s t m a r k e d at least three weeks prior to the conference, fees are $50 less than those above. Additional information can be obtained from Alexander Cruickshank, Gordon Research Conferences, Gordon Research Center, University of Rhode Island, Kingston, RI 028810801 (401-783-4011 or -3372). From J u n e 10 to August 23, Cruickshank can be reached at Colby-Sawyer College, New London, NH 03257 (603526-2870).

Analytical Chemistry

The aim of the Gordon Research Conferences is to extend the frontiers of science by fostering a free and informal exchange of ideas among those actively involved in research in particular fields. At each conference, meetings are held in the morning and evening, Monday through Friday, with the exception of Friday

evening. The afternoons are available for recreation, reading, or participation in discussion groups. To promote discussion and to protect individual rights, it is the established requirement of each conference that no information be used without specific authorization of the individual making the contribution.
