A text-book of veterinary obstetrics : including the diseases and accidents incidental to pregnancy, parturition and early age in the domesticated animals . rior extremit;/, is articulated by a shghtly oval andconvex surface with the last lumbar vertebra, and forms with the spinea salient angle looking down towards the abdominal cavity, named thesacro-vertebral angle. Laterally, it is united to the two coxa, betweenwhich it is fixed like a horizontal wedge. In front it shows the open-ing of the spinal canal. 6 OBSTETRICAL ANATOMY. The summit or posterior extremity likewise offers the opening of thespinal canal, and a surface for articulation with the first tail-bone. Thecentral canal is a continuation of that in the other vertebrae, for thepassage of the spinal cord. In this bone, however, instead of beingcircular it is triangular, and diminishes in width posteriorly. The position of the sacrum is more or less inclined downwards frombefore to behind, according to the breed of the Mare. 3. Coccyx. The coccygeal or tail bones are a series of small, cylindrical, or irregu-larly prismatic pieces, from fifteen to eighteen in number, behind the. Fig. -1. Pelvis ov the Cow.

Differences in the Bones of the Pelvis of other Animals. In all the domesticated animals the coxae are nearly horizontal, andthe ilium has a vertical direction. Goio. In the pelvis of the Cow, the space between the coxge is no greaterbefore than behind ; they are not so solid or voluminous, comparatively,as in the Mare. This is more particularly the case with the ilium, theiliac concavity of which is not so wide. It is more vertical than in theMare. The ischium, though thinner than in the Mare, has a muchwider surface, and is more curved from before to behind and from sideto side ; whi
