198 NORTH-CAROLINA GEOLOGICAL SURVEY. 



No. 21 from the miocene of Pitt county. I found, also, 

 molars, in Pitt county. They occur in a sandy bed, which 

 may be ten or twelve feet above the shell marl. Although 

 there is a close correspondence between the fossil teeth above 

 described and those of the domestic horse, which was intro- 

 duced into this country since its discovery, still, it is probable 

 that it is a different species. If it is maintained that the 

 fossil and introduced species are identical and the same, it 

 follows that the same species was created about the same 

 epoch, in two very different quarters of the globe, viz : Asia 

 and America, and in climates which differed materially from 

 each other. Farther discoveries must be made before this 

 interesting question can be satisfactorily settled. 



SITS SCROFA. HOG. (Fig. 22.) 



The only relic of the hog which has been ob- 

 tained during the survey, is the last inferior 

 molar, scarcely differing from its fellow in the 

 domestic hog. I obtained it at Washington, 

 Beaufort county, from the miocene. It is brown, 

 and is partially mineralized by sulphuret of iron. 

 It has the same claim to genuineness as a fossil, 

 as the teeth of the horse already described. 

 22.) The hog was introduced into this country at 

 the time of its settlement, but as in the case of the horse, it 

 was peopled by this interesting animal a long time prior to 

 its discovery. It also became extinct, and at its settlement 

 was supplied again from a foreign country. 



PROBOSCEDIANS. MASTODON GIGANTEUS. (Fig. 23.) 



The bones of this large pachyderm are not uncommon in 

 the miocene marl of North-Carolina. 



Fragments of ribs and bones of the extremities are the 

 most common. The figure of the superior part of the crown 

 in the margin was taken from a tooth found in Halifax coun- 

 ty. Its enamel is jet black and highly polished. It is the 

 first or small molar of the right side of the under jaw. It is 

 an old tooth with the lubercles worn down, and was probably
