concave, and lipped on each side. The articular sur-faces are oblique, and the spinous process thick, long, and almost horizontal. The Ninth Dorsal has no demi-facet below. In some subjects, the ninth hastwo demi-facets on each side, then the tenth has a demi-facet at the upper part;none below. The T^^tJ^^orsal has an entire articular facet on each side above; no demi-facet below. ~^ ~~ 14 OSTEOLOGY. In the Eleventh Dorsal, the body approaches in its form and size to the lum-bar. The articular facets for the heads of the ribs, one on each side, are of largesize, and placed chiefly on the pedicles, which are thicker and stronger in thisand the next vertebra, than in any other part of the dorsal region. The transverseprocesses are very short, tubercular at their extremities, and have no articularfacets for the tubercles of the ribs. The spinous process is short, nearly horizontalin direction, and presents a slight tendency to bifurcation at its extremity. 6.—Peculiar Dorsal Vertebrae.

The Twelfth Dorsal has the same general characters as the eleventh; but maybe distinguished from it by the inferior articular processes being convex andturned outwards, like those of the lumbar vertebrse; by the general form of thebody, laminje, and spinous process, approaching to that of the lumbar vertebra;and by the transverse processes being shorter, and the tubercles at their extremitiesmore marked. LUMBAR VERTEBRiE. J 5 Characters of the Lumbar Vertebra.. The Lumbar Vertebras (jfig. 7) are the largest segments of the vertebral column.The body is large, broader from side to side than from before backwards, andabout equal in depth in front and behind, flattened or slightly concave above andbelow, concave behind, and deeply constricted in front and at the sides, presentingprominent margins which afford a broad basis for the support of the superin- 7.—A Lumbar Vertebra.
