Mr. Cumberland on the Strata near Bristol. 
to digress, following up the rubble valley where the capstern is, till 
we come on the plain at Clifton turnpike, in order to point out a 
very extensive filling up, perfectly horizontal, of magnesian sandy 
limestone, with a thick under bed of breccia, conformable, containing 
siliceous fragments, as well as calcareous ones, both bouldered and 
fractured, with cavities containing spar of both sorts. 
The first symptoms we discovered of it are 100 feet north of the 
road, where a single stone crops out, worn round. 
Here follow its Beds . 
1. Sandy magnesian limestone. 
2. Another bed larger and angular. 
3 . Another cropping beyond. 
4. Another cropping at 400 feet from the gate, which first in- 
dicates its horizontal position. 
5. A subsidence of the hill, and a long section, the first step of 
the flat in which I first found an angular large piece of 
grey limestone imbedded in the heart of the mass, of which 
6. Is a specimen of that limestone. 
7. Another from a square block slipped forward on the green 
sward shelf and resting on the aggregate. 
8. Another more forward. 
9. From a vein of limestone penetrating a fissure in the mag- 
nesian bed, having stems of encrini. 
10. From a bed of coarse breccia under the magnesian bed 15 feet 
high, and extending the whole of its length, with great 
pieces of limestone, organic, oolitic, and plain, — masses 
of magnesian limestone, quartzose sandstone, soft sand- 
stone, — and all these both rounded and angular. The 
cement ochreous. 
11. Is from a great bed of limestone, whose basset edges crop 
under the magnesian about 10 feet thick* 
♦Jl. From its base with organic bodies,
