NOTES ON ESSEX GEOLOGY.

two papers "On the Pliocene Deposits," and on the "Pleistocene
Period of the Eastern Counties." He re-states his classification
of the Red Crag (1900, 1902), criticizing Prestwich's conclusions.
Essex is referred to on pp. 89-91, 94-96. The second paper
does not specifically refer to the county.
I take some credit to myself in regard to this great memorial
volume, which was finished in 1910 ; firstly because I successfully
avoided writing any contribution thereto, and secondly because
I suggested and fought hard for the simple title Geology in the
Field, under which it appears.
H. B. Woodward's Geology of the London District is one of
the cheapest geologic works, and it certainly cannot be called
by the other adjective usually associated with cheap ; 150
large 8vo. pages and a coloured map are offered for one shilling.
The Memoir is descriptive of the four sheets of the new Geological
Survey Map of the London District (published in 1904) and
gives us an account of the tract, brought up to the latest knowledge
from the underground geology and the Chalk up to the Recent
beds, with information on water-supply and other economic
questions. With this and the work by the same author noticed
under 1906 in their possession most people will be able to know
as much about the geology of an area of something over 800 square
miles (including the south-western corner of Essex) as they are
likely to want.
1910.
M. A. C. Hinton, in a paper on "British Fossil Voles, etc.,"33
had to revise his determination of a Vole from Grays. He says :
—"The result of my study of the Grays fossils is that I am
now unable to refer any of the voles from this locality to recent
species." He notices five forms.
1911.
After 1900 the Geological Society left Essex alone for seven
years, except for mere casual notices, and then we start again
with a paragraph by S. H. Warren on a piece of worked wood
from the freshwater deposit of Clacton.34 The specimen has
also been shown to us.
