The environs of the baths are composed of travertin, overlying Sub- 



apennine clays and sands. The travertin began to be formed after 



the uplifting of the Pliocene; for its layers cover horizontally the 



inclined Subapennine beds ; and a consequence of this uplifting was the 



escape of the tufa- depositing waters, of which the bath -springs are the 



diminished representatives. E. B. T.

 they show a Pliocene age, very few being extinct species. E. B. T.

 These formations occupy an area of about 300 square miles S.W. 

 of the great granitic plateau of Southern Russia. They are exposed 

 in the beds of the middle Dniester and its tributaries, and are almost 

 horizontal. They thin out eastwards, so that the succeeding Creta- 

 ceous beds rest upon older and older Palaeozoic rocks, and at last upon 

 the granite. 



The lowest of the Palaeozoic formations is composed of clay-slates 

 and sandstones resembling greywacke, mostly with few fossils. The 

 second group consists of massive, compact, often bituminous limestones, 

 with beds of marl-slate. Fossils are abundant, and of Upper Silurian 

 age (equivalent to the Wenlock of Wales). The third group consists 

 of slaty marls, with courses of limestone with fossils, also Wenlock. 

 Above comes a group of green shales, with thin beds of black or grey 

 crystalline limestone, which contain numerous characteristic Ludlow 

 fossils, including ScapJiaspis and Pteraspis. Finally, the top of the 

 Palaeozoic series is formed by a group of dark-red micaceous sandstones 

 and sandy micaceous shales, shown to be Devonian by their fossils.
