    the foramen magnum of the occipital bone. From its sides the lateral ligaments extend to the atlas and occipital bone ; and the transverse ligament of the atlas, which confines this process, forms a smooth surface on it posteriorly, while a corresponding one is formed anteriorly where it plays on the smooth surface of the body of the atlas. The superior articular processes, c, c, are large, oblong, slightly convex, and nearly horizontal, corresponding to the inferior of those of the atlas. From the foramina,/,/, are seen slight tortuous depressions made by the vertebral arteries and veins. Jn the foetus this vertebra consists of four pieces. The body and lateral pieces are the same as in the other vertebrae, but the processus dentatus is ossified in the centre, and joined by cartilage to the body like the lateral portions. The vertebrae are connected to each other by cartilage and ligaments. The intervertebral cartilage is seen in Fig. ]. letters o, o, o, o. The letters point merely to that interposed in the lumbar region, as it is here better defined: it is neverthe- less seen between some of the dorsal and between all of the cervical vertebrae ; excepting between the atlas and dentata where it is always wanting. The corresponding articular processes of every two contiguous vertebrae, are enveloped in a strong membranous ligament, called capsular ; and as a joint is thus established, each articular process is tipped or covered with cartilage, styled perichondrium. A strong ligament, styled the common anterior, extends from the atlas to the os sacrum, on the anterior or sternal surface of the bodies, and beneath this, equally strong ligaments, called crucial or intervertebral, bind the margin of the one vertebra to that of the other. A ligament, called the common pos- tenor, extends, in a similar manner, to the common anterior ligament, from the atlas to the os sacrum, behind the bodies ol the vertebrae, or within the bony rings, forming, by their
