    is observed a deep groove, in which the conjoined tendon of the iliacus internus and psoas magnus has played. (Vide Plate viii.) The transverse or horizon- tal branch of the pubes is longer and more slender, and is directed more obliquely upwards and backwards, than the corresponding part of the sound side. The ischium is drawn outwards by the pelvi-trochan- teric muscles, so that the tuberosity is seen situated more externally than on the opposite side. As a consequence of the change of direction outwards of the ischium and of the descending ramus of the pubes, the long diameter of the obturator foramen is found to be disposed nearly transversely, instead of almost vertically. When the head of the femur is dislocated upon the ilium on hath sides, both halves of the osseous pelvis participate in the deformity, and frequently the alterations are so nearly alike on either side, that the resulting malforma- tions are symmetrical. The wings of the ossa innominata in this case, are found less dense, smaller, and more vertical; the anterior inferior spinous processes of the ilia are found prominent, and the depressions existing below them are seen to be deeply grooved by the continued traction of the tendons, which played in them during life. (Vide Plates vi. and VIII.) The horizontal rami of the pubes are found also more slender and longer, extending considerably farther outwards, on each side from the symphysis, than in the 12
