No. 4.—The Marl-bed.—Beneath a thin band of clay under- 
lying the “ Oyster-bed” is a soft mud-stone which is only 
exposed at one or two points at the south end of the quarry ; it 
contains many fossils with the shell preserved, but with the test 
in such a rotten state, that only a few species could be deter- 
mined. From the position of the bed, and from its organic con- 
tents, it appears to be the upper part of the Oolite Marl, as this 
rock is in position and well-developed, within 200 yards of the 
“ Rolling-Bank.” The following fossils were there noted :— 
Chemitzia sp. Nerinea sp. Modiola plicata Sow 
Pecten lens Sow. Cypricardia cordiformis Desh. 
Terebratula Etheridgii Dav. Montlivaltia sp. 
From this Section it therefore appears that the Humphresianus 
beds at Cleeve Hill rest upon the Oolite Marl, and are capped 
by the Lower Trigonia Grit. The equivalent of the zone is only 
partially fossiliferous at Charlton Common, Leckhampton, 
Shurdington, and Cooper's Hill. Doubtless if the rocks were 
worked the characteristic fossils would be found. For the grand 
development of the beds composing the zone of Ammonites’ 
Humphresianus the student must proceed to Dundry Hill where 
they are admirably exposed and richly fossiliferous, being capped 
by the beds forming the zone of 4mmonites Parkinsoni, and 
resting on a thin bed of Upper Lias Sands. 
In Somersetshire and Dorsetshire the middle division of the 
Inferior Oolite is likewise well developed and exposed. 
With these notes by Dr. Wright I will bring to a close the 
question of the ‘ Roadstones” of Cleeve Hill, the position of 
which may now be looked upon as definitively settled, all our 
local geologists having assented to the position laid down by 
the Secretary and Dr Wright. This was the problem proposed 
for solution at our Cheltenham meeting, and it has drawn forth - 
an amount of learning and research most creditable to the 
Geologists of our Club. It is in the elaboration of such local 
details that we can best serve the cause of science ; and it seems 
to me most desirable, that keeping that aim in view, we should 
direct our attention as much as possible to special points of local 
difficulty and interest, whereby we shall be setting before us an 
object, the careful elucidation of which cannot fail to stimulate © 
our individual energies, while at the same time it will secure 
well-merited honour to the Scientific Society to which we belong.
