The reason why the pubic segment passes downwards when the vaginalorifice is opened, is that atmospheric pressure now acts on the vaginal as-pect of the pubic segment (with its weak mesial attachment to the pubis)and drives it further down. As the result of this posture, changes takeplace in the length and direction of the vaginal walls and in the positionof the uterus. These are briefly :— 1. Vagina.—(a.) Both walls elongate. (6.) The anterior follows the direction of the posterior as-pect of the symphysis ; the posterior, the curve ofthe sacrum. ANATOMY OF THE FEMALE PELVIC OEGANS. 81 2. Uterus.—(a.) The normally placed uterus passes nearer the sacrumand nearer the thoracic diaphragm. (6.) The retroverted uterus, fixed or unfixed, becomesmore retroverted. (c.) The retroverted unfixed uterus does not become re-placed so as to he anteverted.

Tip:. 65.Pelvis in frozen section of cadaver in genu-pectoral posture. A, anus; P, perineum; R, rectum; V,vagina ; u, urethra; B, bladder; S, symphysis; /, retropubic fat; C, retroverted uterus ; p p, peritoneum.Between the small intestine and peritoneum is fatty omentum (Simpson and Hart). The results given have been obtained as follows :— a. By observation on living patients, aided by silhouettes of the out-lines of the nude body in the upright and genu-pectoral postures ; b. By study of frozen sections of the female pelvis, and especially bystudy of a frozen section of a cadaver placed in the genu-pectoral posture. For further details on this subject Simpson and Harts atlas may be consulted. Vol. I.—6 82 MANUAL OF GYNECOLOGY. An important practical result follows from these observations. Thevagina dilates or, more properly, the segments of the pelvic floor separate, ex-posing their free margins—the vaginal walls—when a patient assumes thegenu-pectoral posture and the hymene
