100 PACHYDERMATA ORDINARTA. ___ 



24. [In Siam there is a variety of elephant which is white, 

 and held in religious veneration.] 



25. The tusks of elephants furnish true ivory; it is known by 

 the curved lozenge formed lines its cut surface exhibits when 

 polished. That which is obtained from the animal immediately 

 after its death is called green ivory ; it is more esteemed than the 

 other, which comes from tusks, found a long time after they have 

 been separated from the animal. It is said the first is least liable 

 to become yellow. 



26. An elephant, found some years ago in the ice on the coast 

 of Siberia, appears to have been covered with a coat of thick hair 

 and fur, which leads to the supposition that this species, which 

 has long since disappeared from the earth, lived in cold climates. 



27. The Mammoth and Mastodon are extinct species belong- 

 ing to the family of Proboscidians.
