This technique has been used successfully a t nontechnical meetings. There is no reason why it should not be effective for scientific meetings. Still another technique was tried successfully a t the T e n t h Annual Pittsburgh Conference on A n a lytical Chemistry, held in March. I n this instance the object was to determine the best approach to a specific analytical problem. The solutions sought were ones which would give the desired result with the least amount of manpower and complex instrumentation. J. R a y n o r Churchill, Alcoa R e search Laboratories, was moderator. Panelists were R. 0 . Clark, Gulf Research and Development Co., B. F . Scribner, National B u reau of S t a n d a r d s , and R. A. Friedel, U. S. Bureau of Mines. T h e problems presented to the panel, although hypothetical, were practical and realistic. All dealt with the analysis of complex mixtures. To m a i n t a i n spontaneity, the panelists did not go through any detailed rehearsal. The program was set up to allow comments and contributions from the audience. Another new plan for technical meetings is scheduled for a trial at the Western Electronics Show a n d Convention (Wescon), to be held in San Francisco in August. Their "new look" formula is based on the premise t h a t three papers per session is " a b o u t all t h a t a m a n can t a k e at one sitting and still be alert and receptive." A second innovation is to have a "panel of peers" for each session. Two or three men, well versed in the field covered, will comment at the conclusion of each paper. These men will have had an opportunity to review the papers well in advance. This will result in fewer papers, but will afford a greater opportunity for contributions from panel members and from the floor. Papers will be selected from those submitted. T h e papers will be printed and available at the time the convention opens, so t h a t all present can review them before presentation.
