distance beyond the outer coronoid process to the base of the ulnar 
epiphysis, where it disappears. Distally there are two other very obtuse 
ridges above this one. The extremity bears two facets, the larger for the 
cuneiform, the smaller for the pisiform bone. 
The radius is throughout its length a stouter bone than the ulna and 
bears much the greater part of the carpal articulation, viz. : with the 
scaphoid, lunar and part of the cuneiform bones. This articulation is 
transverse to that of the ulna, which is thus at one side of and behind it. 
The head is a transverse oval in section, the narrower end outwards. The 
articular face consists of one-and-a-half trochlez, the latter wider and 
internal. The shaft is a transverse oval in section, with an angular ridge 
along the middle externally, and the distal part proximally. A broad 
groove marks the upper face of the epiphysis, where the shaft has a ver- 
tical inner face.

The elements of the carpus are distinguished for length, and for re- 
duction of width. The anterior faces of all are considerably longer than 
broad, but the longest faces of the cuneiform, scaphoid, and trapezoides 
are antero-posterior. The facets are as usual in the carpus; scaphoid 3; 
lunar }; cuneiform 3; trapezium +; trapezoides +; magnum 2; unciform 
2, The cuneiform has a rather L-shaped external face. The pisiform 
has two proximal facets and is enlarged and thickened distally ; pressed 
inwards it reaches the scaphoid. The trapezium is a small subdiscoid 
bone with convex outer face. The magnum is as broad as deep in front, 
where its surface is swollen; it is produced behind into a spatulate de- 
curved hook. The unciform has a narrow sub-acute hook behind, with 
wide base.
