 vol. i. p. 573. 



Notes that the striations of the sandstone from near Portlock are 

 unUke any form save that attributed to glacial action. The rock is 

 Devonian sandstone. W. T. 



Notes on the Geology of the neighbourhood of Wells, Somerset. 



Proc. Somerset Archaeol. and Nat. Hist. Soc. vol. xix. pp. 50-64. 

 The leading features connected with the Palaeozoic and Secondary 

 rocks in the country around Wells are pointed out. The lead and zinc 

 mines, and the caverns, combes, and alluvial deposits are briefly noticed. 

 In regard to the Cheddar cliffs, the writer advocates the theory of their 

 formation by subaerial agencies. H. B. W.

Notices that in the Triassic rocks marl, sandstone, and conglomerate 

 occur at all horizons and replace each other, though there is a certain 

 local order. W. W.

A sketch of the leading features of the geology of London and its 

 neighbourhood, dwelling more particularly on the great physical changes 

 that the area has undergone since Cretaceous times. The paper is 

 illustrated by a map showing the superficial extent of the different 

 deposits (reduced from the Geological Survey Map), also by a section 

 taken through London from Finchley to Blackheath. H. B. W. 



Worth, K. N. Notes on the Limestone of Yealmpton and its Asso- 

 ciated Hocks. Trans. Devon. Assoc, vol. vi. part 2, pp. 703-706. 



The limestone of Yealmpton is about two miles in length from west 

 to east, and about half a mile in breadth, being the largest isolated 

 patch of this rock occurring between the masses of Plymouth and Tor- 

 bay. An intrusive trap occupies a considerable area north of the village 

 of Yealmpton, and, by an upheaval of the limestone, has produced a 

 fissure, through whicli the river Yealm finds its course. With an im- 

 portant exception, the limestone resembles that of Plymouth in its 

 general character ; but in the latter magnesia does not occur, whilst at 

 Yealmpton it is present in such quantities as to convert large masses 

 into dolomite. Other minerals found are hematite, ochre, jasper, calcite, 

 and asbestos. T. M. H. 



WtJNscn, E. A. Discovery in Arran. Coll. Guard, vol. xxviii. p. 746. 



Announcement made at a meeting of the Glasgow Geological Society 

 of the finding fragments of rocks containing Carboniferous fossils in a 

 bed of conglomerate of glacial aspect, forming part of the large musses 

 of lied Sandstone adjoining the Carboniferous series of Arran. This 

 settled the question of the age of these beds, which had hitherto been 

 doubtful. They are Lower Permian. G. A. L.
