Geological Survey Memoirs accounts of Essex wells were to
be found; but our President (Mr. Holmes) has asked me to
expand this note into a fuller statement, with the localities of
all the wells, so that our members may have an index, as it
were, to the well-literature of the county, the Appendices on
well-sections in the Memoirs including published accounts
with new ones.
