Geological Society. 443 



It is pointed out that the islands, which make up the archipelago 

 of Franz Josef Land, are fragments of a formerly extensive region of 

 plateau-basalts, similar to that of which the Fseroe and the "Western 

 Isles of Scotland must have formed a part. 



2. ' Deposits of the Bajocian Age in the North Cotteswolds. — 

 I. The Cleeve Hill Plateau.' By S. S. Buckman, Esq., F.G.S. 



This paper deals with a portion of the Northern Cotteswolds 

 termed the Cleeve Hill plateau ; and, like a previous communication 

 on the Mid Cotteswolds, it is concerned with the deposits which 

 intervene between the Upper Freestone and the Upper Trigonia- 

 grit. The author shows that in the Cleeve Hill plateau there is, 

 beneath the Upper Trigonia-grit, a further series of beds which 

 have not been found elsewhere in the Cotteswolds, and by placing 

 them in their order he is able to show the sequence of the Cleeve 

 Hill ' Inferior Oolite ' rocks, about which there has been so much 

 misconception. A map is given to show the positions of the 

 different quarries, with notes as to the strata which they exhibit. 



The paper also gives further information concerning the Bajocian 

 denudation, and with it is presented a map showing the areas of 

 the different rocks upon which the Upper Trigonia-grit reposes non- 

 sequentially. Notice is also taken of a water-bearing bed, and of 

 its economic importance. Some remarks are made upon the ancient 

 geography of the Cleeve Hill plateau in regard to streams. Their 

 probable courses are marked upon a map.

4. ' An Explanation of the Claxheugh Section (Co. Durham).' 

 By D. Woolacott, Esq., M.Sc. 



The section of which an explanation is offered in this communi- 

 cation occurs about 2 miles west of Sunderland, and has been 

 noticed by Messrs. King & Howse, and Prof. Lebour. The base shows 

 the Permian Yellow Sands, which are succeeded at the west end of 

 the section by the Marl Slate, thin-bedded limestones, and at the top 

 crystalline limestones without any trace of bedding. At the east 

 end the Marl Slate and thin-bedded limestone are absent, and except 

 when a breccia intervenes the crystalline limestone rests on the 

 Yellow Sands, though the thin-bedded limestone and Marl Slate 

 show no signs of thinning-out. There are also minor complications. 

 The author suggests that the section may be explained by supposing 

 that denudation occurred in a cavern, the roof of which after- 

 wards fell in, and that disturbances were also produced by ' creep '- 

 movements.
