    tremities of the shuttle bone are not much confined, but are loosely attached to the inside of the cartilage and scutiform process by cellular membrane, and also to the lateral edges of the perforans tendon ; and the extremities or waning points of this bone leave ample space for forming a passage for the larger blood-vessels of the foot. These points of the bone, however, are held by a double tie before and behind; the anterior or stronger attachment of it advances forwards to the cartilage at the point where it unites to the coronet ligament. The main attachment, however, of the body of this bone is by a broad, short ligament, to the anterior part of the hollow in the posterior cavity of the coffin bone, situated immediately beneath it; and again also it is attached superiorly by a broad ligament from its superior pos- terior edge, which rising to two thirds of the height of the coronet bone at its back part, is inserted into a short transverse ligament, ex- tending between the back of this bone and the front surface of the perforans tendon, giving it thereby an indirect attachment to this important tendon, but sufficient apparently to occasion their move- ments to be isochronous, or nearly at the same point of time. Surfaces. We next have to consider the surfaces of the coffin bone, where we shall have to notice several new and extraordinary par- ticularities : see pi. 6, fig. 1. The structure of surface which this bone presents in front, and extending some way on either side, is singularly beautiful, consisting of elevated small ribs, or threads of bone, longi- tudinally disposed upon it. These are not placed in exactly parallel lines, but frequently meeting one another at very acute angles, form- ing waving lines, and which give it somewhat of a reticulated appear- ance. A first view of these ribs would lead one to apprehend they were designed to carry the processes or podophylla, having a somewhat corresponding arrangement; but this is pretty clearly not the case, since they are both smaller and more numerous, and the processes are found covering the bone much higher up than these ribs are found to extend, that they are more probably provided for the support of the Reticulum, upon which the processes are situated.
