States argumeats for the siibaerial denudation of the Weald, and the 

 evidence as to the depth of the Palaeozoic surface. Describes the 

 Netherfield boring, giving a list of 34 fossils from the Kimmeridge 

 Clay in it. W. H. D.

The surface is New lied Sandstone. The Coal Measures dip mostly 

 W. at 1 in 3. Ironstone and two coal-seams are worked. A rolled 

 pebble of quartzite occurred in the coal. W. H. D.

Ormerod, G. W. On the Murchisonite Beds of the Estuary of the 

 Exe, and an attempt to classify the Beds of the Trias thereby. 

 Quart. Journ. Geol. Soc. vol. xxxi. pp. 346-354 (plate of 

 section). 

 After mentioning the characters of Murchisonite (a variety of fel- 

 spar), describes the coast-section from Littleham Bay to Maidencombe, 

 near Torquay. The beds seem to belong to the lower portion of the 

 Trias, and consist of sandstones, breccias, and conglomerates. At 

 certain horizons in them the author has detected the presence of Mur- 

 chisonite, which really occurs in the form of derived fragments or peb- 

 bles ; and he endeavours to trace inland, by the aid of this mineral, 

 the several beds which they characterize on the coast. H. B. W.

Devon. Trans. Devon Assoc, vol. vii. pp. 162-170 (2 sections).

 action. 



Pengelly, W. Tenth Report of the Committee for Exploring Kent's 

 Cavern, Devonshire. Rep. Brit. Assoc, for 1874, pp. 1-17. 



Describes work done in various parts of the cave. Gives a full 

 description of the Inscribed Boss of Stalagmite, the dates on which 

 go back as far as 1615. Detailed information is given regarding the 

 Long Arcade (see Geological Record for 1874, p. 29), and of the bones 

 and implements found there. Only bones and teeth of the bear have 

 as yet been found in the breccia, the oldest deposit ; but many flint and 

 chert implements occur here. This is generally separated by crystal- 

 line stalagmite from the cave-earth, in which remains of Hyaena are 

 abundant; over this lies the granular stalagmite. Human bones have
