An account of the diflferent strata and their fossils, pointing out the 



physical changes which they indicate, and the connexion between the 



geology and scenery. H. B. W. 



. Studies and Problems for Somersetshire Geologists. Proc. 



Bath Field- Club, vol. iii. no. 2, pp. 177-182. 

 Indicates some of the points in the geology of Somersetshire upon 

 which more information is needed, and some of the many theoretical 

 questions that have to be solved. H. B. W. 



. The Origin of our English Scenery. Fop. Sci. Rev. vol. xiv. 



pp. 57-66. 

 Draws attention to the various denuding agents, and points out their 

 influence on the formation of the scenery, as brought about by elevation 

 of the strata, and modified by disturbances. The larger features of our 

 country may be traced to the age of the strata, the older rocks as a rule 

 being most elevated and hardened ; while the minor features are depen- 

 dent for the most part on the varying lithological characters of the rocks. 

 The formation of plains of marine denudation, and the origin of escarp- 

 ments and of rivers, are discussed. The amounts of denudation per- 

 formed by sea and by subaerial agencies are compared, calculations con- 

 cerning which prove that the latter are the more powerful. H. B. W. 

 Worth, R. N. Alluvial Deposits on Plymouth Hoe. Trans. Devon. 



Assoc, vol. vii. pp. 150-153. 

 Gives the results of some recent excavations on the ridge of Devonian 

 limestones forming the Hoe, the level of which averages 100 feet above 

 the sea. This is regarded as a platform of denudation ; and the over- 

 lying deposits of pebbles, clay, and sand, having an origin at first fluvi- 

 atile and then both fluviatile and marine, are accounted for by a gradual 

 elevation of the land. T. M. H.

. On the Parallelism of the Scottish and North-Irish Carbo- 

 niferous Strata. Froc. Glasg. Nat. Hist. Soc. vol. ii. part 1. 

 Founds his remarks chiefly on the geological age of the Ballycastlo 

 Coal-field and its relation to the Carboniferous rocks of the west of 

 Scotland as described by Hull, and generally corroborates Hull's views 

 as to the parallelism, lithological and pala}ontological, of the Carboni- 

 ferous rocks in N. Ireland and W. Scotland. J. E. T.

 Considers that a large quantity of the drainage passes through the 

 interstices of the Chalk and rises in Lough Ncagh along a lino of fault in
