Fig. 42.—Right Maxilla of New-born Foal; Medial View. 1, Lacrimal groove; 2, ventral turbinate crest; 3, palatine process; 4, maxillary sinus; 5, 5, area of articulation with palatine bone; 0, groove wliich concurs with one on the palatine bone to form the palatine canal; 7, zygomatic process: S, maxillary tuberosity; 9, junction with nasal bone; 10, junction with nasal process of premaxilla. projects horizontally like a shelf. Behind this the surface is rough for articulation with the palatine bone; this area is crossed by a groove which concurs with one on the palatine bone in the formation of the palatine canal (Canalis palatinus). The posterior part of the bone is excavated to form part of the maxillary sinus. The dorsal border is irregular and scaly. Its anterior part is grooved and its posterior part beveled for articulation with the nasal process of the premaxilla and the nasal and lacrimal bones. The ventral or alveolar border (Processus alveolaris) is in its greater part thick, and presents six large cavities, the dental alveoli, for the cheek teeth. The alveoh are separated by transverse interalveolar septa. There is often a small alveolus for the first premolar ("wolf tooth") close to the first large one. At the bottom of the alveoli there are small openings (Foramina alveolaria) for the passage of vessels and nerves. Further forward the border is narrow and forms part of the interalveolar or interdental space (Margo interalveolaris). Behind the last alve- olus is a rough area, the alveolar tuberosity (Tuber alveolare). The anterior extremity is pointed. It joins the premaxilla, and forms with it the alveolus for the canine tooth. - In the young horse the anterior part of the surface is convex over the embedded parts of the teeth. As the hitter are extruded the surface flattens and becomes concave in old subjects. The form of the underlying teeth may be indicated by ridges (Juga alveo
