On an Accumulation of Shells, luitJi Human Industrial Remains, found on a 

 hill near the River Teign, in Devonshire. ByW. Pengellt, F.R.S., F.G.S. 



In this paper the author described a lai-ge accumulation of shells, all of them 

 such as were derivable from the estuary of the Teign, which had been found in a 

 ti'ench rudely but distinctly cut in the New Red Conglomerate at Rocombe, in the 

 parish of Stokeiuteignhead, about four miles from Torquay. A considerable amount 

 of broken pottery of coai'se character, a brass armlet, a bone hair-pin, and a portion 

 of a quern, all of Anglo-Roman age, were mingled with the shells. 



On Changes of Relative Level of Land and Sea in South-Eastern Devonshire, 

 in Conneccion tvith the Antiquity of Mankind. By W. Pengellt, F.R.S.^ 

 F.G.S. 



In this communication the author, having briefly noticed the characteristics of 

 the existing general coast-line, described a series of phenomena which indicate that 

 within what is known as the Quaternary Period, the whole of south-eastern Devon- 

 shire was at least 280 feet lower than at present ; that by a series of slow and gradual 

 upheavals, separated by protracted periods of intermittence, it was raised at least 

 40 feet above its present level ; that these elevatory movements were followed by 

 one of subsidence ; that since the last adjustment of relative level, the waves have 

 cut back the cliffs so as to form the existing strand, which in some instances is 

 nearly half a mile in width. Having discussed the relative chronology of the facts 

 described, he showed that the Mammoth existed in Devonshire so late* as the era of 

 the submerged forests of Torbay ; and that this period had not closed before the 

 advent of man in the same locality. Lastly, he produced a flint implement found 

 in a patch of gravel on Windmill Hill, Brixham, and which, from its situation and 

 character, must be of an antiquity greater than that of the submerged forests, or 

 raised beaches, or ossiferous caverns, or even the Betula nana clays of the district. 



On the Formation of Valleys near KirJchi/ Lonsdale. 

 By Prof. Phillips, M.A., LL.D., F.B.S., F.G.S. 

 The author called the attention of geologists engaged in considering the theory 

 of the origin of valleys to the necessity of keeping in view not only all the real 

 causes which have been concerned in changing the level and modifying the surface 

 of the solid land, but also the peculiarities of the rocks themselves in regard to the 

 resistance they might offer to the waste occasioned by the mechanical and chemical 

 agencies of water. He proposed to show, in regard to certain great ridges and hol- 

 lows which limited the drainage of the Lime and its branches, that these were 

 plainly sketched out by ancient subterranean movements ; that, in regard to par- 

 ticular streams, as the Lune and the Rother, there must have been valleys on part 

 of their course before the age of the Old Red Sandstone ; and that the courses of 

 others, as Leek Beck and Barbon Beck, were marked out by great faults ; while
