FOSSIL MAMMALIA. 87 



authenticated to have belonged to a $pecies different from the 

 Siberian. 



M. Cortesi afterwards discovered two petrified humeri at 

 some distance, and a lower jaw, in a state of great preservation, 

 on the Monte Pulgnasco itself. 



These bones, as well as the elephant'*s, are in strata filled 

 with marine shells. The two last-mentioned humeri are replete 

 with oysters, and, singular to relate, close to the lower jaw is 

 found the radius of a whale. This would lead us to believe 

 that a part of this stratum had been overturned, for the 

 cetacea discovered by M. Cortesi were in other beds, and much 

 deeper than the last-mentioned. 



In our own country, the remains of the rhinoceros have been 

 found in vast abundance : at Chatham, near Brentford, in the 

 neighbourhood of Harwich, at Newham, near Rugby in War- 

 wickshire, recently at Lawton in the same county, at Oreston, 

 near Plymouth, in a cavern, (as we mentioned before) &c., all 

 found in the same sort of loose strata, in the blue argilla or 

 gravel ; all which Professor Buckland designates as the diluvial 

 detritus. 



We may, in fact, conclude that the bones of the rhinoceros 

 are found in almost every country where the bones of the 

 elephant are found ; that these two kinds of bones accompany 

 each other, and are found with the bones of other large 

 species ; that almost always they are detected under the same 

 circumstances; that their degree of preservation is similar; 

 and that they have been placed by the same geological causes in 

 the position in which they are found. 



Without entering very minutely into osteological details, we 

 shall simply mention that the fossil species are four in number : 

 the first was originally called the rhinoceros of Pallas, from the 

 circumstance of its having been first described by that cele- 

 brated writer. It is the fossil rhinoceros of Siberia, called by 

 the Baron Cuvier, rhinoceros tichonnus. We have already 

 noticed the fact of this animal having been found in the sand
