210 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Jan. 12, 
sand I found a fragment of a shell which Mr. Etheridge considered 
to be a portion of a Cyprina islandica, remarking at the time that 
it was a very difficult piece to determine. At Brick Hill I have 
observed accretions of whitish sand in a bed of light-red loam; and 
on Mount Pleasant the same kind of sand has been met with. It 
may be remarked here that the deposit on Cropthorne Heath, de- 
seribed above, is partially surrounded by beds of freshwater origin, 
between which there is a minimum difference of height of 30 feet. 
H. About three years ago, during the construction of the Eyes- 
ham and Ashchurch railway, a large excavation was made for 
ballast at the base of Bredon Hill, near Beckford, where the follow- 
ing section was exposed, for an account of which I am indebted to 
Mr. W. C. Lucy, F.G.S., of Gloucester.

Basement bed of Lower Lias clay reached at 17 feet below the 
surface. 
On visiting the locality I found that the former excavations had 
been filled in; but near the north-east end of the old workings the 
following section was exposed in a sand-pit.

The beds nos. 2 and 3 contained Oolitic fossils, quartzose pebbles, 
and flints. 
In a sand-pit at Bredon’s Norton I counted as many as thirteen 
alternations of gravel, sand, and clay in a vertical depth of about 
42 feet. 
oy udging from the depth of the basement clay in Section No. 1, 
it would appear that the total thickness of the deposit in the sand- 
pit at Beckford is about 20 feet. From the contour of the surface 
of the ground in the neighbourhood, it seems likely that the beds in 
question form mound-shaped accumulations, which slope upwards 
towards the summit of Bredon Hill, and extend round a considerable 
portion of its base.
