cesses, and always the thinner the nearer to the 

 articulation. Its depth from the line of the alveo- 

 lar processes to the base, is, near the articulation, 

 about four inches and three quarters ; at its farther 

 extremity, two inches and a half. There are no al- 

 veoli in the front part of the upper jaw, and I sus- 

 pect there were no teeth, which, if it was the case, 

 would, besides the azygous branch of the trachea, be 

 another analogy between this animal and the rumi- 

 nating animals that have four stomachs. I once ob- 

 served the front teeth in the lower jaw, but before 

 we proceeded to the dissection, some person had 

 secretly extracted them ; the alveoli, however, in 

 which they were lodged, are large and distinct, and 

 are what causes the depth of this jaw to exceed so 

 much that of its fellow at its narrowest extremity. 

 The other teeth do not extend iniad or backwards 

 above two-thirds of the length of either jaw ; are 

 flat on the corona ; have each but one fang, and 

 stand at small distances, nearly a quarter of an inch 

 from one another ; from which circumstance they 

 remind those who have seen both, of the scattered 

 teeth in the morse or walrus. 



The bones composing the vertebral column are 

 obviously distinguished into Cervical, Dorsal, Lum- 

 bar and Caudal. The cervical are seven in number ; 

 the dorsal, eleven ; the lumbar, thirteen : but the 

 caudal vertebrae have not been enumerated, as part 

 of them was carried away with the cutis. 



The cervical vertebrae, excepting the atlas, have
