    a canal which is considerably curved forwards, and cut perpendicularly to its axis at each extremity. Jlxis.--The axis of the cavity of the pelvis may be represented by a curved line which shall pass through the middle of the canal, so as to follow very nearly the curve of the sacrum. Inferior strait.—This is formed by the inferior opening of the pelvis. Its contour is osseous in front and upon the sides, while behind it is almost entirely ligamentous. Form.—Very irregularly rounded. Dimensions.—The inferior, like the superior strait, has four diameters; an antero-posterior, which extends from the point of the os coccygis to the in- ferior part of the symphysis pubis; a transverse diameter, which goes from one tuberosity of the is- chium to the other, and two oblique, which extend from the tuberosity of the ischium on one side, to the middle of the sacro-sciatic ligament of the op- posite. All these diameters are generally 4 inches in ex- tent; but the antero-posterior may be carried as far as 5 inches by the retrocession of the os coccygis. Direction of the inferior strait.—Its posterior part, as far as the tuberosities of the ischia, is in- clined downwards and backwards, while its anterior part is directed downwards and forwards. This last part constitutes what is called the arch of the pubes. Dimensions of the arch of the pubes. Width.—Superiorly, from 15 to 20 lines; in the middle 2\ inches, and inferior]}- 4 inches. Height.—About 2 inches. vixis of the inferior strait.—The axis of the in-
