2. " Additional Notes on tlie grouping of the rocks of North 

 Devon and West Somerset." By J. Beete Jukes, Esq., M.A., F.E.S., 

 F.G.S. 



Commencing with the country around Wiveliscombe, near which 

 place Sir H. De la Beche had indicated an east and west fault of 

 small extension on the maps of the Geological Survey, Mr. Jukes 

 described the rocks of the district reaching from that place north- 

 west to the Brendon Hills, and westwards to Dulverton, including 

 the valley of the Tone, more to the south. From Dulverton he 

 examined the country towards Simonsbath, and then, proceeding to 

 Barnstaple, made traverses from that place to Challacombe and to 

 Bittadon. Similarly, after examining the neighbourhood of Combe 

 Martin, he proceeded along the north coast in an easterly direction, 

 through Countesbury, Porlock, and Dunster, and across the Williton 

 valley to the Quantock Hills. The observations made during these 

 several journeys were given in detail by the author; and the principal 

 conclusions at which he had arrived in consequence were stated to be 

 the following: — (1) There are three areas of Old Eed Sandstone in 

 this region, namely, a, The Quantock Hills ; 6, The Porlock, Mind- 

 head, and Dunster area ; and c, The Morte Bay, and Wiveliscombe 

 ridge. (2) Each of these masses of Old Eed Sandstone dips under 

 a great mass of Carboniferous Slate. (3) The Coal Measures, the 

 Carboniferous Slate, and the Old Eed Sandstone of Devon, are con- 

 temporaneous with the Coal-measures, the Carboniferous Limestone, 

 and the Old Eed Sandstone to the north of the Bristol Channel. 

 (4) That if the great fault which the author believes to exist be 

 proved to be absent, his other conclusions will not be altogether 

 vitiated, for the red rocks of Porlock and Dunster may then be taken 

 as the top of the true Old Eed Sandstone lying underneath a great 

 thickness of Carboniferous Slate. Mr. Jukes had also been able to 

 construct a geological sketch-map of North Devon in conformity 

 with his views ; and the paper concluded with a few notes ex- 

 planatory of it. 



WooLHOPE Naturalists' Field-clttb. — At a recent meeting of 

 this club, the Eev. W. S. Symonds read a paper, entitled, " Notes on 

 a. visit to the Bone Caverns of the Lesse, in Belgium," by Sir 

 William V. Guise, Bart., President of the Cotteswold Field-club, and 

 the Eev. W. S. Symonds, President of the Malvern Club, of which 

 the following is the most important portion : — 



Ever since the announcement in 1859 and 1860 by our distin- 

 guished countrymen, the late Dr. Falconer, Mr. Prestwich, and Mr, 

 John Evans, of the detection of human implements associated with 

 the bones of the great extinct mammalia in ancient river drifts, and 

 their appreciation and acceptation of the discoveries of M. Boucher 

 de Perthes, the President of the Cotteswold Club (Sir W. Guise) and 

 myself have studied, in various localities, the drifts and gravels of 

 those ancient rivers which long ages ago flowed in broad streams 

 along the existing vales of our Severn, Avon, Wye, Usk, and other 

 rivers. We also visited many of the caves, which, in Somersetshire
