COUNCIL FOR 1844 .

for its extreme rarity, than for the instructive evidence it affords 
to the most casual observer, of the almost incredible size at¬ 
tained, during a comparatively recent epoch in the geological 
history of the Globe, by some species in the Chelonian group. 
The most prominent place that could be fixed upon in the 
Geological room has been selected for the exhibition of this 
valuable donation. 
Along with a collection of Silurian fossils from the neigh¬ 
bourhood of Cincinnati, our zealous corresponding member 
Mr. Joseph Clarke has presented a fine tooth of the Mastodon 
giganteus, a donation particularly acceptable, as the Museum, 
although so rich in the remains of the fossil elephant, had pre¬ 
viously nothing to illlustrate the remarkable dentition of this 
nearly allied but extinct genus of proboscidean Pachydermata. 
Another tooth but from the celebrated locality in Kentucky 
termed Big-bone Lick, and to the very small size of which, 
!Mr. Clarke in his letters directs particular attention, will 
probably be found to be the third milk-tooth of the same 
species. Passing from foreign accessions to those w'e have 
received in Home Geology, a large series of Silurian fossils, 
collected by herself in the neighbourhood of Great Malvern, 
has been presented by Miss Phillips. The collection of fossil 
fishes has been enriched by some beautiful specimens of the 
genera Platysomus and Palseoniscus from the magnesian lime¬ 
stone near Ferryhill, presented by George Hudson, Esq. The 
Lord Mayor has presented a very choice collection of fossils 
from the Cornbrash and inferior Oolite in the neighbourhood 
of Scarborough; and a few valuable specimens from the Coral¬ 
line Oolite have been given by Mr. Pickering and Mr. Barton, 
of Malton. 
From Lord Prudhoe the Museum has received a very in¬ 
structive series of specimens of Stigmaria ficoides, from the 
sandstone of the Coal Measures near Darlington; and a por¬ 
tion of a laro;e fossil stem found in the coal at Wio’an has 
been kindly forwarded to the Museum by S. Hailstone, Esq.
