Near Severcomb Farm the lower beds, with Waldheimia 
ornithocephula, were to be seen resting on a bored surface of the 
Inferior Oolite. (See p. 97.) 
The Fuller's Earth Rock makes no conspicuous feature in this 
neighbourhood. It consists of marls and clays with irregular 
bands and nodular masses of pale grey earthy limestone, about 
5 feet in thickness, having much the same character as the beds 
in Dorsetshire, and being likewise very fossiliferous. It has been 
exposed to the south-east of Highbarrow Hill (H.) ; in the road 
leading from Combe Monkton to the Paper Mill on the west ; 
also above Perrymead, in the lane from Widcombe (W.) to Combe 
Down; and at Bath (B.), above the Royal Villas, west of 
Wesley College. From these beds I have obtained the following 
fossils : 
Ammonites arbustigerus 
Nautilus 
Cypricardia bathonica 
caudata 
Goniomya 
G-resslya peregrina 
Homomya 
Isocardia 
Myacites securiformis 
tenuistriatus 
Ostrea subrugulosa 
Panopaaa ? 
Pecten vagans 
Pholadomya Heraulti 
Ehynchonella concinna

Terebratula globata 
"Waldheimia lagenalis 
ornithocephala 
Serpula tricarinata 
Holectypus hemisphaericus ?

The Fuller's Earth at Wellow presents the same characters as 
the beds worked at Midford. At Combe Hay a shaft was sunk 
to a depth of 30 feet. The opening of the tunnel showed yellow 
fuller's earth 3 feet or more, that passes underground into blue 
earth, 4 or 5 feet. The earth is micaceous in places. The beds 
on top comprised yellow and grey marly clay, with Ostrea 
acuminata, Ceromya, &c. 
The connection of the beds with the Great Oolite, ia shown by 
the following section at " Combe Grove Pit," which was recorded 
by William Smith* : 
Great Oolite
