papers on Charnwood Forest, and even of greater interest to those 

 in the future who shall find nothing but holes and talus heaps where 

 the hills now stand. 



Discussion at the Geological Society as to whether a bed dips this 

 way or that, whether one rock is or is not intrusive into another, 

 or on the nature of the junctions of strata, would occasionally have 

 their acerbity softened by the exhibition of photographs which gave 

 a true picture of the facts, while the record established by such 

 photographs might serve as useful if, perhaps, at times inconvenient 

 reminders. 



The present collection contains many fine sets of views taken in 

 series so as to illustrate particular points. Beginning with the north 

 of England, the coast north and south of Tynemonth, for a consider- 

 able distance, has been photographed, including the Whin Sill and 

 its contacts, the Carboniferous rocks, and the Magnesian Limestone, 

 with its breccia-gashes and other beds of concretions about Marsden 

 and Sunderland. Passing inland, we also owe to Mr. Garwood a very 

 beautiful set of photographs illustrating with the greatest clearness 

 the character and history of the Whin Sill and of the northern 

 boulder-clays. In their own county Mr. Bingley and other members 

 of the Yorkshire Naturalists' Union have given us a series, which it 

 is to be hoped will eventual!}' be completed, that serves as a picture 

 survey of the coast, while inland we have the Clapham, Norber, 

 Gordale, and other districts thoroughly repi'esented. 



Of the Eastern Counties we have very little, and that chiefly of 

 Norfolk, but we have been promised a series, specially taken for our 

 purpose, of the Crag district and parts of the eastern coast-line. Of 

 the Home Counties, again, we have little ; and of the characteristic 

 scenery of the Weald there is not much to be obtained at present, in 

 spite of the work of the East Kent Societj'', to which we owe most of 

 what we have. Of Surrey we have little, of Sussex nothing, and of 

 the Isle of Wight not nearly enough ; but the Dorset coast and 

 inland regions have been well treated by Mr. Cole, Mr. Bingley, 

 Miss Andrews, and others. Parts of Devon and Cornwall have 

 been dealt with in detail, but the prints have not yet been satisfac- 

 torily described and illustrated, partly, no doubt, on account of our 

 limited knowledge of the minuter geology of these counties. 

 Somerset has been treated by Professor Allen, Mr. Armstrong, and 

 others, and its main features have been illustrated, but all that is 

 necessary has not yet been done. 



In the South MidlandCounties, from Hertfordshire to Gloucestershire, 

 but little has been collected, though Mr. Hopkinson has striven, by 

 example and precept, to show what there is to do and how to do it. 

 South and Central Wales, with the border counties of Hereford and 

 Monmouth, are almost virgin fields. Of North Wales there are some 

 capital photographs, including those of the Llanberis district, by 

 Mr. J, J. Cole, but there is much still to be done in a country 

 so rich in evidences of glaciation, with fine rock-structures, types 

 of mountain form, and wealth of outcrop of rocks not so well 

 seen elsewhere. The Ordovician ground of Shropshire has been
