LOWER OOLITIC ROCKS OP ENGLAND : 
There are several sections of Inferior Oolite on the spur 
extending from Break Heart Hill to Stinchcombe Hill. At the 
former locality there is a quarry showing the following section: 
FT. IN. 
Bubbly oolite, used for road-stone - - - 7 
Hard white and more or less oolitic limestone, false- 
bedded. The stone is employed for walling and other 
building-purposes. Near the base it is shelly, and 
yields Lima pectiniformis and Terebratula - 8 
These beds at Break Heart Hill may represent the highest 
beds of the Inferior Oolite the white oolite noticed by Witchell at 
Rodborough,* and seen also in the Horton quarry. (Sec p. 116.) 
Blocks in the wall by the roadside (said to have been taken from 
this quarry) contain small quartz pebbles. The beds are repre- 
sented as Great Oolite on the Geological Survey Map, but they 
appear to pass under the Fuller's Earth. The evidence obtained 
was not quite satisfactory, and therefore I content myself with 
expressing only the opinion that the beds belong to the Inferior 
Oolite. 
The following section south of Dnrsley perhaps shows the 
lower portion of these White Oolite beds resting on the Eagstone. 
It is interesting ns affording evidence of the variable character of 
the Kagstone division : 
More or less oolitic limestones. FT. IN. 
Rubbly marly and somewhat sandy oolite, 
with many examples of Terebratula gldbata ; 
also Myacites and other Lamellibranchs - 10 
<{ Bed with Rhynchonella spinosa 4 
Marly limestone - - - 7 
Marly limestone, Trigonia-bed, with costate 
Trigonia, Ostrea fldbelloides, Lima pectini- 
formis ... 
f White oolitic and shelly freestone ; Trigonia, 
I here and there, near top - 
j Oolitic freestone in regular layers, current- 
L bedded in places 
The Kagstone was well exposed in a 
leading from Dudley to Stinchcombe Hill. 
Cephalopoda Bed, were shown in the lane north-east of Break 
Heart Hill. They comprised micaceous yellow sands, with little 
or no calcareous matter, but with bands of flaggy and false-bedded 
calcareous sandstone. 
The following section, recorded by Mr. S. S. Buckman, shows 
the junction of the Cotteswold Sands with the Upper Lias Clay, 
as exhibited in the road at Stinchcombe, about two miles north 
of Nibleyf : 
'Yellow sands. FT. IN. 
Dark brown argillaceous marl, with 
Ammonites bifrons, A. compactilis, 
Belemnites - - 1 
Brown and bluish shelly and sandy stone 
with ferruginous specks ; A. lifrons, 
Rhynchonella, Terebratula, &c. - 8 
Dark blue clay, with large blue-hearted 
nodules of stone.
