article on this subject in 1894, which was reprinted in the Essex
Naturalist (VIII., 130), and Mr. Dalton's paper of 1890 and
the reports by Messrs. Holmes and Whitaker have already been
referred to. As a contribution to economic geology Dr. Thresh's
paper on the shallow and deep well-waters of Essex, accompanied
as it is by tables of analyses of the waters, is one of the highest
value (Ibid. VII., 28-40). In his recent work, Report on the
Water Supply of the County of Essex, of which a notice by
Mr. Dalton appears in the Essex Naturalist (XII., 62), Dr.
Thresh repeatedly acknowledges his indebtedness to our publica-
tions. Mr. T. S. Dymond's interesting note and analysis of the
manganiferous conglomerate found at Tendring (Ibid. X., 210)
was, until Miss Thresh's recent paper on the same subject, our
only original contribution to mineralogical geology. Mr. Percy
Clark's paper on the encroaching sea on the east coast is a
record of the effects of the high tide of Nov. 29th, 1897 (Ibid. X.,
297). Mr. Monckton's criticism of the official report by Mr.
Hunter Pringle on the land that had gone out of cultivation in
Essex (Ibid. IX.,. 70) may be regarded as a contribution to
economic geology.
Palaeontology and stratigraphy are necessarily treated of
together in many of the communications which we have received
and published. Some of the papers on the Mollusca of Essex
catalogued under Zoology belong to both divisions. The popular
lecture on "A Day's Elephant-hunting in Essex," by the late
Henry Walker (Trans. I., 27), was the first paper published by
the Club after the Inaugural Address. Later, in 1882, Dr.
Henry Woodward, F.R.S., gave us an admirable lecture on
"The Ancient Fauna of Essex" to which he appended a list of
the Mammals from Ilford collected by Sir Antonio Brady and
now in the British Museum of Natural History (Trans. III.,
1-29). The services rendered by our Hon. Member, Mr. E. T,
Newton, F.R.S., in connection with our Palaeontological work
have been acknowledged from time to time in our pages, and it
may be generally said that every important find of vertebrate
remains in Essex has had the advantage of being submitted to
his critical knowledge. Although Mr. Newton's contributions
to our work have not often taken the form of separate publica-
tions, they are none the less valuable, and any record of our past
achievements would be incomplete without some acknowledg-
ment of the part he has taken therein. A paper by him on the
