VOL. XIV. (2) RHETIC ROCKS 169 
as a greyish-green limestone exhibiting “ dendritic” mark- 
ings. As in sections already noticed, the immediate 
superincumbent and subjacent deposits are greenish- 
yellow marly shales. A thin deposit of greyish-black 
non-laminated shales is visible a little to the west, beyond 
which are the red marls of the Keuper. 
The railway cutting to the north of “Highgrove” is 
almost overgrown, but it shows that the bottom bed of 
the Lower Lias (crowded with Ostrea Lasstca and Modiola 
minima and almost horizontal), is on the same level as the 
Red (Keuper) Marls. A fault intervenes, as the evidence 
south of “Highgrove” also suggested: it has a probable 
downthrow of over 50 feet. It is noteworthy that at this 
locality the escarpment is formed by the Keuper Marls. 
A well sunk to the depth of 20 feet at Highnam Green 
passed through the Rhetic Bone-bed, a fact observed by 
J. Jones and W. C. Lucy.’ The field debris shew that the 
subsoil of the district is Lower Lias. Now the Bone-bed . 
at Wainlode occurs 24 feet below the Pseudomonotis-bed, 
and at Garden Cliff the equivalent deposit is 27’ 414" thick. 
If the Bone-bed was passed through ina well 20 feet deep, it 
is obvious that the Rheetic deposit above the Bone-bed must 
be considerably reduced here. The cutting through which 
the Gloucester and Newent road passes near Lassington 
does not elucidate matters, yellowish calcareous Liassic (?) 
shales being visible in close proximity to the Keuper 
Marls, and similar phenomena are shewn further north, 
at Moor End and Catsbury Hill. 
The well-known cutting at Lassington is now almost 
overgrown. The literature relating to it gives the follow- 
ing information :—Sir William Guise remarked that Mr 
Lucy had demonstrated that the Rheetic beds are here

at 20 feet below the surface.” Proc. Cotteswold Club, Vol. ix, (1886-87). p. 82.
