A specimen of Ammonites viator, var., obtained from the Fuller's 
Earth at Godminster, south of Bruton, is now in the Museum at 
Jermyn Street. 
The Upper Fuller's Earth clay was well exposed in a brickyard 
north-east of Maperton, and south-east of the Cock Inn, Holton. 
About 25 feet of grey marly clay was exposed, the beds, where 
dry, being pale and hard, and much resembling those exposed in 
the cliff near Eype. Some small iridescent Ammonites were 
found in the clay, and among the de'bris on the slopes of the banks, 
I picked up a fine slab containing remains of Lepidotus. The 
latter specimen was probably derived from the Forest Marble, 
traces of which occur on top of the clay. 
A well at Cuddlesome to the east cf Bratton, was sunk to a 
depth of 50 feet, through Upper Fuller's Earth Clay to the 
Fuller's Earfh Rock. 
Lamyat Beacon, north-west of Bruton, is a conspicuous outlier 
of Fuller's Earth Clay and Rock ; Lima duplicata and Rhynclio- 
nella varians were found here. At Scale Hill south-east of 
Batcornbe the thickness of the beds was thus estimated by De la 
Beche* :

179 feet. 
I was unable to verify this particular estimate, but the attenua- 
tion of the Lower Fuller's Earth clay is borne out by evidence 
obtained near Frome. 
South of West Cranmore, the Fuller's Earth Rock forms a 
gentle escarpment, not far above the Inferior Oolite, and higher 
up comes the Upper Fuller's Earth clay. The Rock has been 
exposed in the park at East Cranmore, to the south of the Hall, 
and Pholadomya, Modiola, and other fossils have been obtained. 
Wanstrow itself is situated on Fuller's Earth clay, not Great 
Oolite as represented on the Geological Survey map. Grey marly 
clay is shown in the lane on the east side of the village.

Approaching the Mendips we find the beds maintain their 
ordinary characters. East of Stoney-lane House, south-west of
