168 SOME ESSEX WELL-SECTIONS.
To that end I shall be glad for any further information that can
be given, and also for copies of unpublished analyses of waters from
wells or springs.
Having already twenty such analyses, which I believe to be
unpublished, I append these in this paper.
The numbers (in brackets) at the head of each section, or
analysis, are those of the sheet of the Geological Survey Map in
which the site is represented.
Unless otherwise stated, the figures, for thickness and depth, are
in feet.
