    triangular in shape, flattened from before backward, and divided into tour surfaces, a base, and a summit. The posterior surface presents at the median line the rudiments of the vertebral spinous processes, and beneath these there is a groove formed by the extremity of (he sacral canal, and termi- nated laterally by two tubercles. On either side, we observe4 the four sacral foramina, which give passage to the sacral nerves ; more eutwardly. there is a series of eminences resembling the articulating processes of the vertebrae ; and. lastly, two depres- sions, into which are inserted the sacro-iliac ligaments. The an- terior surface is divided by four prominent lines, between which are found superficial grooves; on either side, the anterior openings for the anterior sacral nerves; more outwardly, a concave sur- face, which affords attachment to the piriformis muscle, and which is grooved by transverse furrows, in which the sacral nerves are situated. The two lateral surfaces, at their anterior and superior part, pre- sent a rough, semilunar face, which articulates with the os ilium; in the rest of their extent are rough prominences, to which are attached the sacro-iliac ligaments ; and at the lower portion of the bone there is observed a thin, cutting border, into which arc inserted the sacro-sciatic ligaments. The base presents an articulating surface, on which rests the last lumbar vertebra. The summit, looking downward, is united to the coccyx by a small oval facette. § 2. Coccyx. The coccyx, composed of three or four small bones connected together by iibro-cartilages, is situated at the interior portion of the sacrum. Its posterior surface is convex, and is separated from the integuments by the posterior saero-coccygeal ligament, and affords attachment to the glutei maximi muscles. Its anterior or pelvic surface is smooth, and covered by the an- terior saero-coccygeal ligament ; on this surface are noticed trans- verse lines separating th<' bones. The lateral edges receive the insertion of the anterior sacro- sciatic ligaments, and LScllKVCOCCygea] muscles. Its base is articulated to the sacrum, while its apex affords at- tachment to the levator-ani muscle. § 3. Os Innominatum, The os innominatum is an irregular, broad bone, and, as it were, twisted in two different directions : it is narrow at its middle, and presents two surfaces and four bordera. The external surface is divided into two parts ; the most poste- rior, called toe external Iliac fossa, presents a small. Irregular sur- face, into which is inserted the gluteus maximus muscle; more anteriorly, the superior curved line offers a concave Burface, into Which is inserted the gluteus médius muscle.
