It is quadrangular, flat, and small, extremely thin and often cribriform. The external surface^ forms a portion of the orbit Fig. 17. of the eye, and has a groove in front,^ which completes the canal for the lachrymal sac. From its inferior edge there projects a triangular process'' which articulates with inferior turbinated bone. The edge* ^ ^ articulates with the frontal, ethmoid, and superior maxillary bone. INFERIOR TURBINATED BONE. This is a porous scroll, placed at the inferior 1^ part of the nasal cavity below the ethmoid. Its posterior end is the more pointed. Its internal surface is convex and looks towards the nose; the external surface has a broad hook, processus maxillaris,^ which enters the antrum Higbmorianum, and partly closes it. The superior edge has a triangular process called lachrymal, which articulates with the unguis. The portions of the edge in front and behind this process rest upon ridges of nasal process of the superior maxillary and palate bone; there is frequently a process upon this edge which unites with the ethmoid bone. VOMER. A single bone, forming a large portion of the nasal septum, coasislinsj of two plates of compact structure. It is a flat bone with four^edges. The superior is the thickest, having a deep groove between two lips (ate) for the reception of the processus azygos of the sphenoid. The inferior is the longest, articulating with the nasal crista of the palate suture. The anterior unites with the ifasal la- mella of the ethmoid, and the posterior is thin, sharp, and concave, separating the posterior openings of the nose. INFERIOR MAXILLARY. Is also single, having a parabolic curve; placed at the inferior portion of the face. It
