IOC) Mr. De la Beche on the Geology 



IY\\\, between Tor Mohani and Upham, the calcareous slate and limestones are 

 much confused. At Butterhill quarry the limestones are much disturbed. 

 On the new road from Torquay to St. Mary Church, at the entrance of the 

 rocky dehie, irregular, detached asid arched strata, have a very picturesque 

 elTect, tlie arcli appearing- to be almost a work of art. 



The coast also from Babbacombe to the Black Head, exhibits confused 

 strata of limestone and argillaceous sliale ; at the latter place we may observe 

 a thick, bent stratum of limestone included in the solid trap* : this limestone 

 is very crystalline. Hope's Nose, with the Leadstone, Oarstone, and Thatcher 

 llocks lying- immediately near it, are composed of limestone much contorted 

 at the cove north of the Thatcherf. This mass of limestone is detached from 

 tiie limestones on the west, that is, above the level of the sea ; and, beneath, 

 they are probably connected with the Torquay beds, for the Thatcher Rock 

 is composed of them. Kent's Cavern, lately celebrated on account of the 

 remains of elephants, rhinoceroses, hyainas, bears, deer, wolves, &c. found in 

 it, is situated in these limestones;};. 



From Barton the limestone extends along- the hill to King's Kersv/ell, where 

 Exeter red conglomerate covers it for a sliort distance : but, at the lower part 

 of the village on the old Dartmouth road, the limestones again come in, and 

 are continued to the top of the hill, where a quarry exhibits their contortions §. 



2. Limestones on the South of Tor Bay. 



Like those on the north of the same bay, these are g-reatly disturbed, as 

 may be seen along- the coast from the Berry Head to Saltern Cove, near 

 Goodrington. At Marstink quarry near Paington, thin strata of semi-cry- 

 stalline limestone dip north about 20°. At Saltern Cove, limestones are mixed 

 with, and disturbed by, trap, which has greatly altered the character of the 

 limestone at the points of contact. In one of the projecting- points the altered 

 limestone does not effervesce freely with acids ; it contains corals. 



Reddish shale resembling that on the north side of Tor Bay, and similarly 

 situated beneath the limestone, occurs much contorted at the western point of 

 Saltern Cove. In some places it is traversed by quartz veins. 



Old Red Sandstone. — JUngere Gramcache. Grcs Rouge Intermediaire. 

 The general character of this rock is best exhibited near Cockington.

+ The Rev. Joliu M'^Encry, who lias formed a very valuable collection of these remains, 

 intends, I believe, to publish an account of them ; and Professor Buckland will probably do the 

 same in the continuation of his " Reliquia; Diluvianae."
