" The humerus is much flattened. On its posterior aspect there 

 is a \a.vge foramen, situated under, and occupying the whole of the 

 internal part of its head, which is in form crescentic from before 

 backwards : over the internal and posterior part of it a groove 

 passes. The distal end of the bone has two tubercles for articula- 

 tion. There are two prominent trochlece on its posterior surface, on 

 which work the two sesamoid bones of the elbow-joint. The form 

 of the larger of these is flattened, and of the smaller trapezoid, with 

 truncated edges.
