an olecranon fossa containing the normal olecranon. Beyond this is 
a thick rounded swelling, which, however, can hardly have been pro- 
minent before dissection (fig. 2). This is the normal outer condyle 
of the humerus plus another of a right humerus applied to the normal 
bone at nearly a right angle. A prominence somewhat to the outer 
side of the front of the normal humerus represents the internal condyle 
of the right one. Between this and the fused external condyles is 
the joint for the right olecranon. There is but a faint trace of a fossa 
above it. Between the two internal condyles is a very small coronoid 
fossa on the front of the normal humerus. Thus 
it appears that to this left humerus is added a Fig. 3. 
part of the lower end of a right one, so applied 
that the outer condyles are fused and the right 
inner condyle projects forward. To illustrate this 
I have made a model (fig. 3), by sawing off 
obliquely a great part of the outer condyle of 
a left humerus and applying to it a part of the 
lower end of a right humerus cut in the same 
way. Each humerus bears its own ulna.

The dorsal side of the carpus was well exposed in the original 
dissection but the description was not anatomically correct. The palmar 
aspect cannot be studied. The carpus is so convex that it is not 
possible to get a satisfactory photograph. The relations of the bones 
are shown in the diagram in which they are represented as in a level
