sections. An imusnally valuable feature is the very line bibliography 

 appearing at the end of each chapter, by the aid of which anyone can refer 

 to plenty of literature on a subject in which he may be particularly in- 

 terested. The index is also very full, and obviously carefully made. 

 Wherever possible, a description has been illustrated by the aid of a 

 ■diagram, sketch, or photograph ; there being over 700 illustrations in the 

 volume. No one interested in mining (and the number has enormously 

 increased just recently!), can afford to be without this Treatise. 



The Witham and The Ancaster Gap, a study of river action, by F. M. 

 Burton, F.G.S. London : A. Brown and Sons. 32 pp. 



In this little pamphlet Mr. Burton continues his physiographical 

 studies in the county of Lincoln, and well explains the various changes 

 which have occurred in the course of the Witham from time to time. 

 These changes are summarised in a ' Syllabus ' given in the pamjihlet, 

 and some of them are illustrated by a tracing from an old map, which 

 forms the frontispiece. Unfortunately there is nothing in the pamphlet 

 to indicate the year in which it was published. For the benefit of Biblio- 

 graphers, etc., we may state that our copy was received on August 27th, 

 1910. 



RECENT GEOLOGICAL PAPERS, Etc. 



We have recently recei\ed a number of interesting geological papers 

 and pamphlets which should be brought before the notice of our readers. 

 Mr. A. R. Horwood sends a report on the ' Investigation of the Fossil 

 Flora and Fauna of the Midland Coalfields,' in which he urges the members 

 of the Warwickshire Association of jNIining Students to forward specimens 

 to him for identification. :\Ir. S. H. Smith has an interesting paper in 

 the Northumberland Society's Transactions, dealing with the ' Faunal 

 Succession of the Upper Bernician.' In this the author gives lengthy 

 lists of fossils from the Lower Carboniferous Series of Northumberland, 

 and also a list Oi localities at which exposures occur, with details. There 

 are some plates of the typical fossils. The same author reprints from the 

 Proceedings of the Durham Philosophical Society a note on ' The Grains- 

 gill Greisen,' in wliich he records the presence of Wolfram. 



Mr. W. Morley Egglestone has published an admirable memoir on 

 ■' The Geology of the Little Whin Sill, Weardale, co. Durham.' In this 

 he gives petrological details of the rock and of its associated minerals, 

 pectolite, iron pryites, zinc-blende, galena, quartz and calcite. It is 

 interesting to notice that the whinstone is used in Weardale for bushes 

 and bearings for the axles of waterwheels at corn mills. An interesting 

 discussion on the paper, together with the author's reply, also appears in 

 Vol. XXIX. of 'The Transactions of the Institute of Mining Engineers.' 

 "Mr. J. W. Jackson has published a ' Preliminary Report on the Exploration 

 ■of "Dog Holes" Cave, Warton Crag, near Carnforth, Lanes.', in 'The 

 Transactions of the Lancashire and Cheshire Antiquarian Society,' Vol. 

 XXVII. Details are given of the various animal remains found, which 

 have already been referred to in these columns. There are illustrations 

 -of bone and earthenware relics and of other objects found in the cave. 

 Mr. T. S. Ellis, 9, Denmark Road, Gloucester, sends an article on the 

 ' Winding Course of the River Wye ' (10 pp., i/-), in which he describes 

 the later history of the river, and its relation to its neighbours, the Severn 

 and the Usk, the Towy and Ystwith. The same writer also favours us 

 with a copy of his paper on ' The Lower Severn Valley, River and Estuary, 

 from the Warwickshire Avon to the Bristol Avon ' (' Proceedings of the 

 Cotteswold Naturalists' Field Club,' Vol. XVI, pp. 241-263). The pamphlet 

 is illustrated by a number of plates and diagrams illustrating the changes 

 in the course of the river.
