False-bedded oolite and thick beds of

between these two masses of false- 
bedded oolite is not apparent west of 
the bridge, for the clay-parting dies 
away. Moreover fossil-beds with 
T. maxillata, Ostrea, &c. occur irregu-

The White Limestone is well seen at Jackment's or Jacuman's 
Bottom ; an appellation said to be derived from its position on the 
Roman way known as Akeman Street. 
At Tetbury Station and in adjoining quarries to the south- 
east, we have evidence of the following series of beds :

I obtained Ceromya concentrica, C. Symondsi, and Pholadomya 
(cast), from the fossil-bed in one of the quarries. 
The full thickness and sequence of the Lower Beds cannot be 
very clearly made out. There are shallow cuttings on the rail- 
way, and in adjoining roads, to the south-east of Haresdown 
Barn, and near Rodmarton Cottage ; and these show a variable 
set of beds beneath the white limestones, &c. These lower beds 
include grey limestone with white oolite grains, about 15 feet 
thick; and lower down, 6 feet of sandy beds that approach Stones- 
field Beds in character. In one cutting, however, west of the 
road near Rodmarton Cottage, there were shown a pisolitic bed 
3 feet thick, resting on a brecciated and nodular limestone 
16 inches thick, with tubiform markings ; and these beds resemble
