FOSSIL MAMMALIA. 11 



leagues, do yet present analogous peculiarities. Scattered rocks 

 composed of the same stone are divided in diflPerent directions. 

 Their fissures are filled with a calcareous concretion, very hard, 

 and forming a sort of red ochreous cement, in which bones mixed 

 with terrestrial shells are found imbedded. These bones, 

 which are not petrified, have been almost all of them broken 

 previously to their incrustation. These breccie are found in 

 the rock of Gibraltar, at Cette, Nice, Antibes, in Corsica, in 

 Dalmatia, and in the island of Cerigo; depositions nearly 

 similar are found at Corcud, near Terruel in Arragon, in the 

 Vicentine territory, and in the Veronese. 



In the rock of Gibraltar have been found the bones of a 

 ruminant animal, which the Baron thinks may appertain to 

 antelope, and the teeth of one species of the genus lepus. 



In the deposition at Cette, the bones of rabbits, of the size 

 and form of such as now exist, have been found ; others of 

 the same genus, but one-third smaller; rodentia, similar to the 

 campagnol ; birds of the size of the wagtail, and snakes. 



In the osseous breccia of Nice and Antibes are found the 

 bones of horses, and ruminants' teeth of the latter order, of 

 species about the magnitude of cervus. 



The breccia of Corsica contains debris of lagomys, existing 

 at present only in Siberia, and bones of a rodens resembling 

 perfectly the water-rat, except that it is smaller. 



We find in those of Dalmatia, the bones of ruminants of 

 the size of dama. 



Of the bones in the breccia of the island of Cerigo, we have 

 no account, except from Spallanzani, who imagined that 

 human bones existed among them. This opinion, however, 

 appears totally destitute of foundation. 



In the deposition of Corcud, the bones of asses and oxen 

 have been found, resembling those of the present day, and of 

 sheep of a very diminutive size. 



In the Vicentine and the Veronese breccia, the antlers and 

 bones of cervus have been found, together with the bones of
