Having occasion to go to town about this time, I took with 
~ me some shells, which had been carefully put aside by Messrs 
~ Rozerrson, which I shewed to Mr Eruerines, and he named 
_ the following :— 
At 267 feet—Astarte and Cerithium 
» 281/3 1 —Astarte, Cyprina, Avicula inequivalis, Gryphites 
vy 292/8 1» —Ammonites semi-costatus 
u 340/6 1 —Very hard indurated bed 
wv 316 ». —Lima and Avicula, tough bed 
» 323/29 » —Ammonites semi-costatus, Gryphites. 
uv 340 » —Cerithium, Pleuromya 
un 344 » —Tornatella or Cylindrites 
The finding of this latter shell satisfied Mr Erurrmper as 
to the position of the boring, as it belongs to the lower bed 
of the Bucklundi, and he expressed himself confident that if 
_ the boring were continued, in 80 feet the Rheetics would be 
_ passed through, and he urged it should be resumed ; but, after 
- what had taken place, I did not feel justified in advising Messrs 
Rozerrson to do so. 
I will now state briefly my reasons for believing that the 
Bheetic beds were nearer the surface, and the basis upon which 
I formed that opinion. 
If we look at the map it will be observed that the Lower 
‘Lias on the other side of the Severn varies from one to two 
‘miles from the alluvium meadows to where it rests against 
the new Red Sandstone. »That from the Island at Gloucester 
to Highnam Green, wheré, when a well was sunk a few years 
ago to a depth of about 20 feet, the bone bed of the Rhetic 
was passed through (as the late Mr Jonn Jongs and myself 
saw .) Ms 
That the Rhetic beds come up at Wainlode, four miles 
from Gloucester, on this side of the Severn, and also three 
niles south, at Elmore. 
At Wainlode the Ostrea bed is 83 feet above the Tea-Green 
Marls, and at Westbury 35 feet, with a dip of 3 degrees.
