Of course there are problems with anonymity in the peer-review system; authors are few who have not at some time in their careers felt real or perceived offense from a negative review. In the mathematical sciences, which I know the best, this is a recurring problem. Various measures have been proposed from time to time. Some years ago, for instance, one journal experimented by delet

M.C. ESCHER: Art and Science. H.S.M. Coxeter, M. Emmer, R. Penrose and M.L Teuber, eds. Elsevier, New York, 1986. 402 pp. $50. Who has failed to notice that exposition in the mathematical sciences is more pictorial lately? Today, it is not uncommon to find technical mathematics illustrated with drawings. And not just with elaborate symbols which, before the morning coffee, resemble an intimidating jumble. There have even appeared in august mathematical journals whole articles consisting entirel
