    from before backwards, whilst the lower fragment is concave. This form of the fragments conduces to the displacement upwards, outwards, and back- wards, of the lower upon the upper fragment. An examination of the lower end of the radius affords a satisfactory explanation of the course taken by this fracture. Internally it presents an articular surface for the head of the ulna, above which is a small triangular surface, ending in a ridge. The compact tissue forming this small surface is at right angles to a force acting from before backwards, or from behind forwards. Externally is the styloid process, and from its base proceeds another ridge, which I shall call the supinator ridge. It extends upwards, losing itself on the convex surface of the outer border of the radius. Poste- riorly there are other ridges. These ridges, with the prominences in front, strengthen the lower end in such a way that we might almost anticipate the direction wdiich the fracture would take from force applied in the manner to be presently mentioned. If we commence posteriorly, and draw a line along these ridges where they join the remaining com- pact tissue of the body of the bone, it would present a well-defined convexity, indicating the weakest part of the bone, and that in which the fracture often occurs. In front the line taken by the frac- ture will also be somewhat convex. The lower end of the upper fragment will be convex in front and behind, whilst the upper surface of the lower fragment will be concave. In some cases of frac- ture there is an obliquity from before, backwards
