    PAGE 32 The sacroiliac junction. The sacro-vertebral angle. Fig. 9. 32 The right os innominatum. Fig. 10. 33 Division of the os innominatum at the acetabulum, with Fig. 11. 34 Auricular facette of the innominatum—the pubal facette—sacro-sciatic notch—plane of the ischium. 35 Os pubis. Fig. 12. 36 Os pubis—or bar-bone. Fig. 13. Symphyseal ligaments. 37 Fig. 14, with account of pelvic ligaments. 38 Opening of the pelvic joints—cases of relaxed symphysis. 39 The whole pelvis—plane of the strait—its inclination. 40 Fig. 15. Inclination of the plane of the strait. 41 WiganoYs figures, 16, 17, of the inclination of the straits. 42 Wigand's figures, 18, 19. 43 Plane of inferior strait. Fig. 20. 44 Diameters of pelvis. Fig. 21. 45 Ten pelves measured. A table. 46 Table of diameters from authors. 46 Axis of pelvis. Fig. 22. 47 Cams's curve, with Fig. 23. 48 The recent pelvis. Fig. 24. 49 Reflections of the pelvic peritoneum—recto-vaginal peritoneal cul de sac—muscles within the pelvis—blood-vessels, &c. 50 Fig. 25. Contents of pelvis. CHAPTER II. MECHANISM OF THE PELVIS—MECHANISM OF LABOR, AS IT DEPENDS UPON THE RELATIONS OF THE PELVIS AND THE FGETAL HEAD. 51 Flexion, and obliquity of the head. Fig. 26. 52 Dip of the occipito-mental diameter in vertex labor—rotaticfi. 53 Extension illustrated by Fig. 27—Influence of the perineum in causing extension of the head—restitution. 54 Rotation of the shoulders to the pubis, in vertex labors—mechanism of second position. Fig. 28. 55 Mechanism of third position. 56 Fourth position. Fig. 29. 57 Fig. 30. Showing that when the vertex in fourth position cannot come to the pubis, the occipital extremity of the occipito-frontal diameter must escape first—fifth position. Fig. 31. 58 Sixth position—a case related—an occipito-posterior position, in which the restitution carried the vertex back to the sacrum. 59 Face presentations. Figs. 32, 33. 60 The doctrine in face cases—bring the chin to the pubis.
