The glenoid cavity of the scapula is an oval, narrower next the cora- 

 coid, and not produced at that extremity into a tuberosity. In the manus 

 the cubito-carpal articulating surface of the carpus is not very convex in 

 any direction. The proximal surfaces of the scaphoid and lunar bones are 

 concave. The two proximal surfaces of the cuneiform are about equal; 

 that for the pisiform the longer by a little. The scaphoid's greatest diame- 

 ter is transverse. The transverse is the shortest of the lunar. The sizes of 

 the anterior faces of the carpals of the second row are, in diminishing order, 

 the unciform, the trapezium, the trapezoides, and least the magnum. The 

 trapezium is wider than long, and extends distadt over the proximal 

 extremity of the second metacarpal. The proximal extremity of .the second 

 metacarpal is concave; that of the fourth is convex. The fifth has a 

 proximal external tuberosity. Its shaft is proximately as stout as those of 

 the others, which are of subequal proportions, but the second and fifth con- 

 tract more rapidly.
