The Hon. Mr. Strang ways on the Geology of Russia. 39 



ballsj exactly as is seen in England and Fiance : chalk is seen also on the 

 Dniestr near Moghilef *, and on the Gallician frontier between Brody and 

 Radzivilof ; the sandstone of Lemberg- intervening between the chalk and the 

 Carpathian mountains. The most southern part of this secondary tract is 

 composed of a soft yellow shelly limestone, extending along the shore of the 

 Black Sea from the heights of the Dniestr and Odessa, across the mouth of the 

 Bug and the Dniepr towards Cherson : and similar strata, especially the oolites, 

 are found in Moldavia and Valachia. The country,, though bare of wood, is 

 fertile. 



Secondary strata, which I suspect to be partly a continuation of these lime- 

 stones, form the High Steppe of Pallas, along the Don and lower Volga, and 

 probably stretch further north. 



The greatest part of the interior of the Crimea, as described by Pallas, En- 

 gelhardt, and Parrot, appears to consist of strata of similar character to those 

 above mentioned; but gradually rising towards the mountains of the south. 

 These strata form w hat is called the steppe of the Crimea, and are continued 

 on the eastern side of the Sea of Azof, along the northern edge of the Cau- 

 casus towards the Caspian. The descriptions and maps of the Crimea repre- 

 sent it as affording a most perfect example of a regular series of diluvian es- 

 carpments. 



* In the ravines communicating with the Dniestr near Moghilef, is found siliceous wood, in 

 considerable quantity : it much resembles that of Portland. Siliceous wood resembling that of 

 the Palm tree has been found near Tomaspol.
