PROCEEDINGS OF METROPOLITAN SOCIETIES. 325 
(from whom a valuable collection of British plants had also been 
received), and others. The Council had appointed local secretaries 
in different parts of the kingdom ; also at the Cape of Good Hope 
and South Australia; and had. made arrangements with the Soci- 
ety of Edinburgh for an annual exchange of plants, which would be 
an advantage to the members of both societies. The Report was 
carried unanimously. By the ballot for officers for the ensuing 
year, J. E. Gray, Esq., F.R.S., was re-elected President, who there- 
upon appointed J. G. Children. Esq. V.P.R.S. and Dr. Macreight, 
F.L.S. Vice-presidents. The President’s address was congratula- 
tory, pointed out the advantages derived from an interchange of 
plants, drew attention to the increase of the society’s herbarium from 
the excursions made in the vicinity of London, and the benefits ac- 
cruing to each member therefrom ; and hoped for continued exer- 
tions in the same way, asa considerable number of rarities had thus 
been already collected. 
GEOLOGICAL SOCIETY. 
Novemser 5th.—The first meeting of this society for the pre- 
sent season was held on this day. Professor Owen read a paper on 
some fossil remains of Pachydermata, obtained from the fresh-water 
deposits of the Isle of Wight, and which were referable to the ex- 
tinct genera Chwropotamus, Anoplotherium, and Palzotherinm, the 
first of which had not previously been ascertained to occur in that 
locality. The discoveries of Mr. Allen and Mr. Pratt had long 
since proved the existeffte of both the others in the quarries of Bin- 
stead ; but the collection which had recently been made by Mr. Fox 
enabled the author to determine more fully several of the species 
which had been first ascertained by Cuvier in the gypsum quarries 
of Paris; and to show also that the Cheropolamus, which was 
most nearly allied to the Peccary ( Dycotyles ) among existing ani- 
mals, another of the extinct generic forms which had been recon- 
structed by the illustrious French naturalist from fragments found 
in the celebrated ossiferous deposit of Montmartre, occurred likewise 
in the contemporaneous older tertiary beds of this country. The 
portion of this curious animal described by Mr. Owen consists of a 
nearly perfect right ramus of the lower jaw, nearly nine inches in 
length, and containing three tuberculated true molars, and two co- 
nical anterior or false molars, with the socket of a third, and part of 
what was deemed to be the tusk or canine. The last true molar, 
which was unknown to Cuvier, presents the same structure as the 
corresponding tooth of the Peceary, as is likewise the case with the 
two others: but the false molars have each two fangs, and are rela- 
tively larger than in the Hog tribe. In the outline of the in- 
ferior border of the jaw, the Charopotamus also resembled the Pec- 
cary ; but in the size of the coronoid process, and prolongation back-
