118 Osteological Description of the 



pulley; it can bend but not turn : at the bottom it becomes 

 nearly as broad as at the top, and terminates in two short 

 apophyses ; one anterior, which is pointed, and one trun- 

 cated ; the latter receives the semilunar; between them is a 

 fossa, which receives the scaphoid; its greatest contraction 

 js towards its upper third. 



The cubitus, almost every where triangular, has towards 

 the bottom a cavity which receives a projection of the radius ; 

 it is terminated bv a cavity i'or the cuneiform bone; the 

 olecrancon is very much compressed, swelled at the end, and 

 forms the fourth of the whole bone*. The carpus is com- 

 posed of eight bones; the scaphoid and unciform are very 

 large ; the pisiform is almost round. 



On the scaphoid and trapezoid is a bone out of rank, 

 which is analogous to the trapezoid, and the only vestige of 

 the thumb ; the semilunar, the great bone, which here i:^ 

 one of the smallest, and the unciform have large protu- 

 berances on the palmar facef. 



The exterior metacarpian is articulated with the unciform, 

 and has on its interior side two facets for the mean; the lat- 

 ter is articulated with the great bone by a very concave facet, 

 and with the unciform bv a small one. The interior is ar- 

 ticulated with the trapezoid and the great bone, and touches 

 the middle one by a small triangular facet.

The pelvis is exceedingly broad; the wide part of the 

 bones of the ilium being 0*5 in breadth: its spine is forked, 

 which distinguishes it from the w'hole series of the bones 

 of the ilium in the elephant: the angle which touches 

 the sacrum is also more elevated; the neck in particular is
