Essex Well-Sections. 
difficult to understand the section. It is possible that the 
strong disturbance has affected the water-yielding power of 
the Chalk, by squeezing the rock and closing up the fissures, 
which may be the reason of the want of success in getting

I had been content at first merely to note in what 
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.
