A map of the Urals, prepai'ed by the mining engineers, has been 

 published by A. Karpinsky — " Geologische Karte des Ostabhanges 

 des Urals," 3 sheets, 1884. Scale 1 : 420,000 ; with enlarged parts 

 of 1 : 210,000. 



Appendix. Geological Map of Europe. — Although only a small 

 area of Europe has yet been published by the Surveys described 

 above, enough is now known of its geological structure to justify the 

 preparation of a complete map, on a scale sufficiently lai'ge to allow 

 all the main subdivisions to be shown. This task has been under- 

 taken by the International Geological Congress, which, during its 

 meeting at Bologna in 1881, appointed a Committee to carry out the 

 work. The Committee is formed as follows : — 



For Germany . 



,, Austro-Hungary 



,, France 



,, Great Britain . 



,, Italy 



„ Eussia 



The map will be in 49 sheets (7 by 7), measuring in all about 

 12 feet by 10 feet. The scale is 1 : 1,500,000 (about 231 miles to 

 one inch). The expense of producing this Map is far beyond the 

 means of the Congress ; it was therefore resolved to apply for 

 assistance to the various Governments of Europe. In most cases 

 the money required was immediately promised, and in others 

 satisfactory arrangements for the amount required have been made. 

 England's share of the expense is £400, yearly instalments of which 

 have been given, as required, by the Royal Society from its Govern- 

 ment Grant. For this sum 100 copies of the Map will be returned. 



The Map is being prepared at Berlin, and will be published there 

 by Eeimer & Co. A new topographical map is being prepared by 

 Prof. Kiepert. Streams and railways are given in detail ; in select- 

 ing the names of places special care is taken to mark those of 

 geological interest or importance ; the names of mountain-chains and 

 chief hill-ranges are given, the heights of the summits being marked 

 in metres. The meridian is Paris, 2° 20' E. of Greenwich. The 

 topography is far advanced, and much progress has been made with 

 the geology. 



The subdivisions represented on the Map will probably be nearly 

 as follows : — Alluvium and Quaternary, Pliocene, Miocene, 

 Oligocene, Eocene, Cretaceous (3 divisions), Oolite (2), Lias, 

 Trias (2), Permian (2), Carboniferous (3), Devonian (3), Silurian 

 (2), Cambrian, Crystalline Schists etc., (perhaps 2), Granite, Erup- 

 tive rocks (perhaps 6 or 7). 



The geological information, as supplied by the various members of 

 the Committee, is inserted under the supervision of W. Hauchecorne, 

 the Director of the Geological Survey of Prussia ; whatever success 

 may attend the work will be mainly due to his energy and care.
