1977 Gordon Research Conferences Three of the Gordon Research Conferences of particular interest to analytical chemists will be held this summer in New Hampshire. T h e conferences, which were established to extend the frontiers of science, provide opportunities for informal discussion and recreation in addition to the more formal presentations by scheduled speakers. T h e unique feature of these conferences is the opportunity afforded for exchange of information and ideas not normally achieved through the usual channels of publication and presentation at scientific meetings. T h e purpose of the programs is to bring experts up-to-date on the latest developments, to analyze the significance of these developments, and to examine what lies ahead in a particular area. This year, three separate full week programs will cover analytical chemistry, ion exchange, and separation and purification. T h e technical schedules for these conferences are given below. Those interested in attending should write for an application form to A. M. Cruickshank, Pastore Chemical Laboratory, University of Rhode Island, Kingston, R.I. 02881 (401-783-4011). Mail for the director's office from J u n e 13 to August 26 should be addressed to A. M. Cruickshank, Director, Gordon Research Conferences, Colby-Sayer College, New London, N.H. 03257 (603-526-2870). Topics of many of the other scheduled conferences of interest to analytical chemists include environmental sciences: air (Aug. 15-19), magnetic resonance (June 13-17), and toxicology and safety evaluations (Aug. 1-5).
