RUSSIA IN EUROPE, AND THE URAL MOUNTAINS, GEO- 

 LOGICALLY ILLUSTRATED. 



By Sir RODERICK MURCHISON, G.C.S. With Coloured Map, Tables, 

 Woodcuts, Sections, &c. 2 vols. royal 4to. 



"This work extends the Geological classification of strata, as determined by 

 modern investigations in the British Isles, France, and Germany, to European 

 Russia and the Ural Mountains a region nearly twice as large as those districts 

 of Europe previously examined and described. It is thus an appeal to Nature on 

 a very grand scale, which, in confirming the sound inductions of the Geologist, 

 has elicited, it is hoped, new and important views."
