When the Editor of Antiquity invited me to write some notes on the Zürich Congress, it was agreed that they could only be considered as personal impressions, and not a formal report. The unfortunate human limitation which debars one from being in two places at once is always irritatingly obtrusive on such occasions, and a decision on which of several simultaneous papers to attend is likely to be decided by spinning a coin at the last moment, so that one can do no more than record one's own impressions, and something of those of friends to whom one has talked.
