THE ESSEX NATURALIST.
the skins and referred to several visits he had himself paid to Western
Canada in earlier years, when he had made acquaintance with all the
forms of birds exhibited.
On the President's motion, the thanks of the meeting were accorded
to the several exhibitors and donors.
Mr. C. Nicholson read a paper oh "The Rosy-marbled Moth in Britain
(with special reference to Essex)" (printed ante, p. 29), and exhibited speci-
mens of the moth and its cocoon. 
Thanks were passed to Mr. Nicholson for his paper.
The President then called upon Mr. George Morris, who read a paper
on "Some Neolithic Sites in the Valley of the Essex Cam" (see ante, p.
49), illustrating same by lantern-maps and diagrams, and by the exhibi-
tion of specimens of implements and flakes from the various sites described.
An interesting discussion followed the reading of the paper, in the course
of which Mr. Hazzledine Warren remarked that he agreed with the author
in regarding the implements exhibited as being of Neolithic date, although
some advanced students of to-day would call them Palaeolithic; he added
that patination is due to local conditions and not to age.
A hearty vote of thanks was accorded to Mr. Morris for his communica-
tion, and the meeting adjourned.
VISIT TO THE MUSUEM OF ECONOMIC BOTANY.
KEW GARDENS (541st MEETING).
SATURDAY, 18TH FEBRUARY, 1922.
A bright sunny day, which reminded one that spring was not far dis-
tant, tempted some 25 members to attend this meeting, which had been
arranged for the purpose of making an inspection of the Museums in the
Kew Gardens, under the conduct of our Vice-President, Professor G. S.
Boulger, F.E.S., F.G.S.
The party assembled at 2 o'clock at the Victoria Gate entrance to the
Gardens, where it was met by the Conductor, and at once proceeded to
Museum No. 1.
Here Professor Boulger began a detailed account of the history of the
building and its collections, and remarked that the latter, though all of
economic importance, were arranged in strict scientific sequence of the
natural orders of plants, and not according to their economic value; but
he pointed out that economic characters run with the natural orders with
remarkable unanimity.
It is impossible here to give a resume of Professor Boulger's lecture,
which was of the most detailed character and which lasted until the visitors
were turned out of the Museum at closing time! Briefly, the Professor
touched upon each of the more valuable economic products of the Dicotyle-
dons (to which Class this Museum is devoted, Museum No. 2 being in
like manner given up to the Monocotyledons), such as opium, gamboge,
tea, cotton, kapok, cocoa, flax, linseed oil, senna, gum arabic, etc., treating
each subject with a wealth of personal knowledge which did not fail to
impress his hearers.
Before leaving the Museum the President expressed the cordial thanks
of these present to our Vice-President for his valuable exposition, and
