. The comparative anatomy of the domesticated animals. Veterinary anatomy. great development of its transversal diameter, the considerable dimensions of the spinal foramen, and the thinness of its body. The intra-rachidian face of the latter is divided into two portions by a transverse ridge; one anterior, furnished with ligamentous imprints, exhibits, laterally, two deep excavations, which lodge the venous sinuses; the other, posterior, is smooth and concave from side to side, and forms an articular surface into which is received the odontoid j)rocess of the axis; this surface resembles the cotyloid cavity. The inferior spine of the body appears as a large tubercle. The head is absent, and is replaced by two concave facets. The anterior articular processes have their gliding surfaces looking downwards; they are joined to the two preceding facets to constitute two large diarthrodial cavities, which correspond to the occii)ital condyles. There is no spinous process, but a rough- ened surface instead. The transverse jiro- cesses are large, flattened above and below, incline forwards and downwards, and are provided with a thick rugged lip. Pos- teriorly, quite at their base, and on each side of the spinal foramen, they show two large vertical facets wliich rej^resent the posterior 4, Posterior, or cervical fora- a^-ticular processes : these facets are uneven, are confounded with the articular cavity oi the upper face of the body, and correspond to the two analogous facets of the axis. Each transverse i)rocess is pierced at its base by two foramina, which traverse it from below upwards. The posterior rejn-e- sents the vertebral foramen of the other ver- tebra ; while the anterior is continued to the external surface of the process by a wide, deep, but very short channel, running from without to within, and joins a third fora- men, which enters the spinal canal. These last two ojienings, with the demi-canal which unites them, rejilace the anterior notch; the posterior is
