76 THE CAT. (chap. hi. more than twice as long as it is high.; hut its anterior half is higher than its posterior, and presents two foramina, one of very considerable size, the spheno-palatine, foramen directly over a very much smaller posterior palatine foramen (Fig. 43, B). More than the hinder half of the inferior margin of this ascending plate is smooth, free, and concave ; the rest of that margin joins the maxilla. Its hinder end joins the pterygoid. The hinder half of its superior margin joins the orbito-sphenoid and the pre-sphenoid, to which latter the concavity its of upper margin is adjusted. Its more anterior portion is applied against the outer side of the ethmo-turbinal. The horizontal lamella (Ji) projects inwards (from the anterior two-thirds of the inferior margin of the ascending lamella), and joins its fellow of the opposite side in the middle line, and there also joins the inferior margin of the hinder part of the vomer. Its anterior margin is convex, and adjoins the hinder margin of the palatine plate of the maxilla of the same side. Its hinder margin is concave and free, forming the posterior limit of the bony palate and the anterior boundary of the meso-pterygoid fossa. The posterior palatine foramen (3) very near to, or at, its anterior margin. The palatine articulates with the maxilla, the vomer, the lachry- mal, the os planum, the orbital plate of the frontal, the pre-sphenoid, and the orbito-sphenoid. § 36. The vomer (Fig. 49, v) is a single, thin, median bone grooved above, and extending down vertically from the basi-sphenoid

It is a very long and narrow bone, very obliquely quadrangular in shape. Its hinder portion, however, expands horizontally, to support and unite with the inferior and hinder parts of the ethmo-turbinals—its hinder end under-lapping the anterior part of the pre-sphenoid. In front of the expanded part, the grooved upper surface of the vomer receives within its groove the lower edge of the mesethmoid; while, still more anteriorly, the septal cartilage of the nose is received within the. same groove. The lower margin of the vomer unites
