ON THE FOSSIL BONES OF PACHYDERMATOUS QXTADRUPBDa. 



an engraving of the posterior surface, plate 10, fig. 7, and of its late- 

 ral surface, plate 10, fig. 8. This specimen formed part of an elephant 

 about ten feet in height. 



In order to facilitate the means of an exact comparison between the 

 skulls of the three species, I shall hereunto annex a comparative 

 table of their dimensions in the specimens which have been placed at 

 my disposal.

4. Comparison of the Lower Jaws. 

 The lower fossil jaws, found separately, and at immense distances 

 from the skulls of Siberia ; for instance, those found on the banks of the 

 Rhine and in Lombardy, have presented us with characteristics, which 

 those of the skulls had led us to anticipate.
