Upper or most Modern. ‘The last he regarded as a connecting link 
with the Glacial series. 
In a paper on “ The Anglo-Belgian Basin of the Forest-bed of 
Norfolk and Suffolk, and the Union of England with the Continent 
during the Glacial period,” the Rey. J. Gunn came to the conclusion 
that the forest bed is the estuarial deposit of some great river or 
rivers which flowed westwards, closed to the south by a ridge of 
chalk hills, but open to the sea on the north; and that this ancient 
river is now represented by the several rivers which flow into the 
German Ocean between the mouths of the Scheldt and the Rhine. 
He strongly suspected that the separation of this country from 
the Continent took place more recently than geologists generally 
supposed. 
In introducing his “ Additions to the List of Fossils found in 
the Boulder Clay of Caithness,” Mr. Peach suggested that the clay 
had been transported to the shores of Caithness by icebergs, which 
when launched picked up some of the sea bottom with its organisms, 
and on their voyage, wherever they touched, added to their burthen 
by picking up more organisms, stones, &c.; that on finally strand- 
ing, the mud, stones, sand, and shells of Caithness became imter- 
mingled with them; and that when the ice slowly melted the burthen 
was dropped confusedly together, but was capable, nevertheless, of 
telling distinctly the story of the voyaging and collecting of the 
berg. 
Mr. Brown, in a communication on “The Drift of the Weaver 
Hills,” described a deposit of siliceous sand, white plastic clay, and 
other materials, at an elevation of upwards of 1,000 feet, where it 
is overlaid by the Boulder clay. The author was of opinion that it 
was not of fresh water origin, and that it was perhaps contemporary 
with the late Tertiaries—for example, the Norwich. crag. 
The aim of Mr. Pengelly’s paper, “On Raised Beaches,” was to 
call attention to the facts: Ist. That accumulations of blown sand 
occasionally assume the character of raised beaches. 2nd. That it 
is not safe to conclude, in the absence of other evidence, that raised 
beaches differing in height by as much as even thirty feet, neces- 
sarily belong to distinct periods. 38rd. That it is possible that what, 
in a small vertical section having the direction of the coast lie, 
appears to be but one raised beach, may really be two. 4th. That, 
all other things being the same, raised beaches are likely to be most 
numerous on a coast composed of durable rocks. 
In Dr. Ransom’s paper “On the Occurrence of Felis lyna asa 
British Fossil,” a description was given of a series of caves or fissures 
and especially of one known as the “ Yew-tree Cave,’—which on 
the borders of Nottingham- and Derby- shires ocenr im the Permian
