he shows, as before stated, that there is a regular sequence of for- 
mation throughout the country to Cork Harbour, the only variations 
being in the direction and amount of the dips due to undulations in 
the formations, and in the strata themselves. The localities de- 
scribed in greatest detail are the valleys of the Bride and the vicinity 
of Cork. 
Mr. Griffith is of opinion, that the bands of carboniferous lime- 
stone in the valleys of the south of Ireland are only patches of a 
vast deposit which once covered the old red sandstone and transition 
districts. 
The memoir was accompanied by an extensive collection of fossils 
illustrative of the different formations of the country, but more 
particularly of the Cork limestone. This collection was presented 
by Mr. Griffith to the Society.

A paper was read, ‘‘On bones of Mammoths found in the deep 
sea of the English Channel and German Ocean,” by Capt. J. B. 
Martin, Harbour-Master, Ramsgate, and communicated by Sir 
John Rennie, F.G.S. 
The Ramsgate fishermen employed in trawling in the North Sea 
and English Channel, frequently bring up in their gear, fragments 
of fossil bones. These remains being generally charged with 
worms, and covered with fetid marine substances, are seldom ca- 
pable of being preserved; but specimens in a good condition are 
sometimes procured, and of the greater part of these, Capt. Martin 
has been the fortunate purchaser. The following is a list of the 
principal specimens : 
1. A tusk, 9 feet long, and 8 inches in diameter at the lower 
end; but the part containing the alveolar cavity is wanting, and 
therefore its length or greatest diameter, when perfect, cannot 
be ascertained. The outside consists of very thin laminz, and 
the interior of a soft substance resembling putty. ‘The specimen 
was found in 1827, and is in the possession of Mr. Forster of 
Ramsgate. 
2. In 1835, a very large decayed bone, and a tusk 11 feet long, 
but so soft as to be cut through with a knife, the centre bemg of 
the consistence of pipe-clay, were dredged up between Boulogne 
and Dungeness. The bottom of the channel, at that point, con- 
sists of blue clay charged with rounded pebbles. 
3. In 1837, a fisherman, trawling between the two shoals called 
Varn and Ridge, and in 21-fathom water, enclosed in his net a 
vast mass of bones, but of which only a humerus was preserved. 
The upper articulation is wanting, but the length of the portion 
obtained is 38 inches; the circumference of the upper part of 
the shaft, 31 inches; of the centre, 20 inches; of the part just 
above the condyle, 31 inches: and the width of the condyle is 
10 inches. ‘The Varn and Ridge lie in the mid-sea between Dover 
and Calais, forming a line of submarine chalk hills, which trend
