(4) The Pembroke- Mendip anticline, continued east- 

 ward into the anticline of the Vale of Pewsey near Devizes, 

 and past various inliers at Ham, Kingsclere, Peasmarsh 

 near Guildford, Westerham Common, Charing near Maid- 

 stone, and so through the faulted area south of Ashford to 

 the sea, south of Hythe. (Professor Prestwich takes this 

 farther north to the sea, north of Dover.) 



(5) The South Welsh syncline, corresponding with the 

 London Basin amongst the newer rocks. According to 

 Professor Dawkins this syncline probably widens eastwards. 

 He considers that the Coal- Measures which were reached 

 by piercing the newer rocks at Burford in Oxfordshire 

 occur there owing to the existence of this syncline (Pro- 

 fessor Prestwich expects coal to be found in isolated basins 

 in this syncline in the Isle of Thanet, Essex, Hertford- 

 shire and Oxfordshire). Our author places the Dover 

 Coal-Field in the southern part of this syncline and re- 

 commends search to the west of Dover. He also 

 advocates trial shafts to be sunk in various parts of 

 the eastern extension of the South Welsh syncline, which 

 he believes to be broken up into isolated basins (such as are 

 found to the west where there is no covering of Mesozoic 

 rocks, as, for instance, the Bristol and Somersetshire Coal- 

 Field, and that of the Forest of Dean). The detection of 

 these basins will be the result of experimental borings. The 

 paper is illustrated by a map showing" the presumed eastward 

 extension of the various western folds enumerated above. 



We have no paper definitely devoted to the study ol 

 the Carboniferous beds of the European Continent to 

 notice. Of Asiatic Carboniferous (or newer) deposits we 

 have several accounts in the volume of the Records of the 

 Geological Survey of India published in the latter half of 

 1894. W. Saise (8) takes the Karharbari Lower Coal- 

 Seam as the base of the Barakar beds (a grouping previously 

 made by T. H. Hughes), and evidence is given against 

 the inclusion of some of the Coal-Seams in the underlying 

 Talchir beds as proposed by Feistmantel. There is no 

 evidence of unconformity between the Talchir and Barakar 

 beds, but the different facies of the two groups justify their
