 Mr. Cuvieris of opinion that these animals must 

 have lived and died in those countries and situa- 

 tions in which their bones are discovered at the 

 present day, and that all the individuals then exist- 

 ing perished, simultaneously and suddenly, from 

 some great catastrophe, concerning the nature of 

 which we are unacquainted. The entire body 

 with its flesh, discovered in Siberia, proves that 

 the animal was seized by the ice immediately after 

 its death, and the thick coat of wool and hair with 

 which it was covered would well adapt it for a 

 residence in cold climates. The isolated bones, 

 which are met with every where, are often ob- 

 served to have marine animals attached to them, 

 which establishes, in an incontestible manner, that 

 since their dispersion they have been covered by 

 the ocean, under w hich they have been buried a 

 considerable time.
