the existing as well as of the fossil elephant. The bones of 

 the hind feet are remarkably smaller than those of the fore 

 feet : it seems that the ungual phalanges had more motion 

 than they have in the elephant, and approached nearer to 

 those of the hippopotamus. 



Other teeth of this animal have been found in several 

 other parts of the world. In the neighbourhood of Dax and 

 of Orleans ; in Piedmont, in different parts of Lombardy ; 

 at Peru; the field of giants, near Santa Fe, in Terra Firma ; 

 and in the province of Chiquilos, in Paraguay. 



From the investigations made by Cuvier, he considers 

 that there are five species of this genus: — 1. The mastodon 

 of the Ohio. — 2. The mastodon with narrow teeth, found 

 at Simorre. — 3. The small mastodon^ that with small teeth. 

 — 4. The mastodon of the Cordilleras ; the large animal with 

 square teeth. — 5. The mastodon of De Humboldt, which is 

 the smallest. 



He was also able to determine, that, in an upper jaw of 

 the second species, there had been three teeth ; the foremost 

 having four points, and one at the hinder part ; the middle- 

 most, six pair of points and two supplementary behind; and 

 the hindmost, five pair of points, and one supplementary 

 and undivided. 



A tooth of the mastodon of the Cordilleras was found, 

 by De Humboldt, at the height of twelve hundred toises, 

 near to the volcano of Imbaburra, in the kingdom of Quito. 



In the cliffs at Harwich are found fragments of bones ; 

 flat, seldom more than three inches wide and twelve inches 

 long ; their surfaces smoothed, as if by attrition ; highly 

 ferruginous, and yielding a sharp sound when struck upon. 

 From the uniformly flat shape of the fragments, nothing 

 can be inferred from them respecting the animal to which 

 they belonged. 



Within these few years, a tooth, with a ferruginous im- 

 pregnation, was found on the beach at Harwich. This tooth
