    smooth, inclined, nearly plain surface, covered by the obturator internus, and levator ani muscles, also the inner orifice of the obturator hole, with its groove, and lastly, a second surface, narrower above than below, which corresponds to the bladder. The os innominatum has four edges. 1. The upper edge, called also the iliac crest. This is thick, uneven, convex, inclined outwards, except posteriorly, where it is directed a little in- wards, twisted upon itself like an italic s, thinner in the middle than at the extremities, and longer in the female than in the male, being six inches in extent measured directly and eight ;when its turnings arc followed, 2. Lower edge, shorter than the other, inclined inwards, presenting below a thin crest, more ob- lique and blunter in the female, bent outwards form- ing with its fellow on the other side, the pubic arch or angle. This crest is surmounted anteriorly by a vertical surface, of an elliptical form, which uniting with a similar surface, on the bone of the other side forms the symphysis of the pubes. 3. Posterior edge, very irregular, oblique from above downwards, and from without imvards, at its union with the upper edge it forms the posterior su- perior spinous process of the ilium, a large project- ing spine, which is separated by a notch from an- other spine, called the posterior inferior spinous pro- cess. This latter is rounded, flat, sharp, and formed by the posterior part of the surface, which articu- lates with the sacrum. Beneath this process there is a deep notch, which with a part of the sacrum
