TRANSACTIONS OF THE 



exfoliated ; this surface is slightly concave in the direc- 

 tion of its axis, and marked with several foramina, for 

 the transmission of vessels and nerves; basal surface, solid 

 and rounded ; dental aspect of the bone varying from one 

 inch and a quarter, to one and six-eighths inches in thick- 

 ness, marked with a longitudinal depression or groove, 

 for the lodgment of vessels and nerves, exterior to the 

 sockets: total length of this surface 17 inches, contain- 

 ing four sockets, and part of a fifth, all with remains of 

 teeth more or less fractured and destroyed ; the four 

 posteriorly situated are the remains of double molars, 

 similar to that displayed in pi. 22, fig. 1,/. Anterior to 

 the first molar, a vacant and depressed curved space 

 occurs, and then a pyramidal rising of the alveole, which 

 contains a canine tooth, pi. 23, fig. 1, which has been 

 fractured on its exterior and superior aspect, and from 

 the internal surface of which the enamel has scaled; 

 another vacant space follows this tooth to the anterior 

 fractured extremity of the bone; the portion of tusk re- 

 maining is one inch in height, and one and a half inches 

 in breadth at base. The fragments of the molars vary 

 from two and a half inches to two and six-eighths inches 

 in length, and from half an inch to six-eighths of an inch 

 in breadth on the fractured surfaces. 



The bone being fractured both anteriorly and poste- 

 riorly, leaves us at a loss to estimate the total length of 

 the jaw, and consequently, the total number of teeth. 



Dimensions — Total length of this fragment eighteen 

 inches ; height posteriorly, five inches — anteriorly, four 

 inches; breadth posteriorly, two and a half inches — 

 anteriorly, rather less than two inches. 



Vertebrae. 



These are from different parts of the column. Great 

 discrepancy is observable in their relative proportions 

 and size; and they are more or less imperfect; but all
