Letters to the Editor

Dear Editor: ... May I also take this opportunity to praise the staff of the AI Magazine for a most informative and professional journal, and one which I find increasingly important for acquainting me with the latest progress in American research. I look forward to the continuing success of the Association in all its activities. Dear Sir, Yours sincerely, Marten E. Bennett Gzllingham, Kent, UK I would like to comment on something disturbing that appeared to be revealed at the recent I J C AI conference at Karlsruhe. The background to it is the "Marietta affair." At the industrial exhibition associated with the conference a Germany company, Marietta, was due to mount an exhibit.
