FOSSIL HOG AND MASTODOX. 255 



which grew among the roots of the long hair. These 

 afford an undeniable proof that this animal had belong- 

 ed to a race of elephants inhabiting a cold region, with 

 which we are now unacquainted, and by no means fitted 

 to dwell in the torrid zone. It is also evident that this 

 enormous animal must have been frozen up by the ice at 

 the moment of its death. 



" Mr. Adams, who bestowed the utmost care in col- 

 lecting all the parts of the skeleton of this animal, pro- 

 poses to publish an exact account of its osteology, which 

 must be an exceedingly valuable present to the philoso- 

 phical world. In the mean time, from the drawing I 

 have now before me, I have every reason to believe that 

 the sockets of the teeth of this northern elephant have 

 the same proportional lengths with those of other fossil 

 elephants, of which the entire skulls have been found in 

 other places."^ 



Sns. Hog. 



Only single bones and teeth of this tribe have been hi- 

 therto met with, and these appear to belong to the sus 

 scrofa, or common hog. They are found in peat mosses, 

 r in very new alluvial deposites. 



Mastodon. 



This is entirely a fossil genus, no living species having- 

 hitherto been discovered in any part of the world. It is 

 more nearly allied to the elephant than to any other ani- 



* It is worthy of remark, that although fossil bones of the elephant 

 were described as such in the middle of the 10th century by Aldrovan- 

 dus, it was not until two centuries afterwards that this opinion was 

 credited. In the intermediate time they were described as lusus na- 

 turae, bones of giants, skeletons of fallen angels, remains of marine ani- 

 mals, or of colossal baboons.
