It is divided into a horizontal portion, containing the lower teeth, and an upright or ascending portion, terminating in the joint or temporo-maxillary articulation at each side. These portions are named re- spectively the horizontal and the ascending ramus of each side, the chin being considered as placed between them in front. The ascending ramus on each side is bounded superiorly by two structures, viz., in front by a sharp and thin process of bone termed the coronoid process, and behind by another process of a thick and some- what tuberose aspect, termed the condyle, and constituting the articular portion of this bone. Between the coronoid process in front and the condyle behind, the flat substance of the ascend- ing ramus is hollowed into a deep notch called the sigmoid notch. Proceeding downwards, we find the internal aspect of the ascending ramus perforated by a canal opening downwards into the substance of the bone. This is the inferior den- tal foramen for the transmission of a nerve and
