For the guidance of those who may be interested in studying the- 
sections, the following detailed notes are given. 
Beds 1 to 10 were exposed in the railway-cutting east of Langton 
Bridge, and beds 3 to 6 again in an adjoining quarry south of the railway. 
The second cutting east of Langton Bridge showed beds 12 to 15, 
resting on clay possibly the same as bed 11. 
A quarry east of the road, south of the railway and south of the Lime- 
kiln, showed beds 6 to 9, highly inclined towards the north ; bed 9 
here being rich in specimens of Terebratula maxillata, &c. They were 
overlaid by beds seen in the road-cutting immediately north, consisting 
of creamy limestones and marls, from which I obtained Ostrea acuminata 
and 0. subrugulosa. Still, higher, there were fine oolitic limestones, to- 
gether representing beds 11 to 14, the actual thickness of which was not 
clearly determinable. 
Beds 23 and 24 were shown in the Lime-kiln quarry, where they dip 
towards the S.S.E., suggesting a synclinal arrangement, if indeed the beds 
be not faulted on the south. 
The long cutting, west of the Hook Norton tunnel-cutting, showed a 
clear sequence of beds 14 to 23, resting on clayey strata : the top beds 
represent the mass of the White Limestone. 
Beds 20 to 23 were shown in the cutting east of the lane south of Roll- 
right Heath Farm, and beds 23 to 27, &c. were shown in the cutting on 
the west side of the same lane, and in that near the Pest House. 
The cutting adjoining the western end of Hook Norton tunnel, showed 
Upper Lias, &c. faulted against the Great Oolite. These latter beds 
were much obscured, but there were marly clays with bands of earthy 
shelly and oolitic limestone, and an oyster-bed with Ostrea acuminata, 0. 
Sowerbyi, Cyprina, Rliynclionella concinna, &c. These beds, I believe, 
represent those numbered 10 to 14, and perhaps as low as No. 8. Details 
were noted by*Mr. Beesley, who, however, regarded the beds as belonging
