240 LOWER OOLITIC BOCKS OF ENGLAND : 
The Fullonian series is exposed in places along the railway 
between Frotne and Radstock. Near the 118 and 119 milestones, 
grey marly clay with occasional bands of marly limestone were 
to be seen. Ostrea acuminata is abundant in the clay, and Rhyn- 
chonella varians in the stone. 
South of Green Parlour, Radstock, there was exposed a section 
of grey marly clay, with nodular beds of pale earthy limestone, 
yielding Waldheimia ornithocephala, Rhynchonella varians, Avicula 
costata, and Ostrea acuminata. There is a specimen of Ammonites 
viator, var., from the Fullonian Beds of Radstock, in the Museum 
of Practical Geology. The Lower Fuller's Earth appears to be 
very thin, but the Rock perhaps occurs at irregular horizons. It 
spreads over a flat area, and has been quarried immediately south 
of Green Parlour. 
The Fuller's Earth Rock has not been traced (on the Geological 
Survey Map) further north than Stoney Littleton, in the main 
escarpment south of Bath. It has however been partially 
mapped in the Wellow outlier, but this tract of ground and that 
to the west of Combe Hay need revision. An examination of 
the ground near Upper and Lower Baggeridge, between Wellow 
and Norton St. Philip, shows that Fuller's Earth Hock occurs 
along the scarps in an attenuated condition. In the road-cutting 
leading from Wellow to Upper Baggeridge Farm, there may be 
seen (above the Inferior Oolite), grey clay with Ostrea acuminata 
and Rhynchonella varians, and this is overlaid by brown earthy 
and rubbly limestone with R. varians, Waldheimia ornithocephala. 
Isocardia, Modiola sowerbyana, Ostrea Sowerbyi, Pecten de missus 9 
and Pinna. These beds may be traced around the hill to Hassage, 
and thence towards Norton St. Philip. 
Fuller's Earth Clay with occasional bands of earthy limestone, 
was well exposed in the railway-cuttings between Wellow and 
Midford. In this neighbourhood we first come to the beds that 
have been worked for economic purpose?: and the fuller's earth of 
commerce has been obtained at various points in the outliers of 
Wellow, South Stoke, and Combe Monkton. It has been worked 
at Wellow, Combe Hay, near Dunkerton, Duncorn Hill, near 
English Combe, South Stoke, Odd Down, Midford, Combe 
Monkton, Lyncombe, and Widcombe. 
The total thickness of the Fullonian series in this neighbour- 
hood was estimated at from 135 to 150 feet by Lonsdale.*
