	An update of Genetic Maps 1984, appropriately titled 'Genetic Maps
1987' has been published.  On the other hand, I didn't check to see whether
they had actually updated the E. coli map. (Other maps were obviously
brought up to date).

	In the restriction map paper itself, there is a full-page vertical
figure showing the alignment of the physical and genetic map.  The agreement
is relatively extraordinary.  Of course, since this is only a map for a
single 8-base cutter, the true alignment awaits the hexamer restriction
map, which may be a few years in getting here (or maybe not...).
