. The Principles and practice of gynecology : for students and practitioners. US. G15 leave for the uterus ouly the iutermediate space, and would constitutea condition seldom or never realized in health. Suppose a straight line coincident with the vesicovaginal wall,Figure 340, to be continued through the cervix to the sacrum. Thisline represents approximately the anteroposterior diameter of thepelvis. The length of the vesicovaginal wall is two and a half inches,and, supposing the cervix to be just midway between the symphysisand the sacrum, the distance from its posterior wall to the sacrummust also be two and a half inches. Add to the sum of these twoparts of this anteroposterior diameter one inch for the diameter ofthe cervix, and the anteroposterior diameter of the pelvis becomes sixinches, instead of the normal four and one-third, which proves thatthe cervix njust normally be much nearer to the hollow of the sacrumthan to the symphysis. Since the length of the vesicovaginal wallplus the diameter of the cervix measures three and one-half inches, Correct drawing of the pelvic organs. Semi-diagrammatic. it follows that the distance from the posterior wall of the cervix tothe hollow of the sacrum must be the difference between four and one-third and three and one-half inches, or five-sixths of an inch. Thesemeasurements are approximations. Again, suppose the uterus.

It is therefore clearthat anteversion must be the normal position, because the uterus andsacrum would otherwise occupy the same space. Figure 341 represents, according to Schultze,^ the location andposition of the virgin uterus and its surroundings—the bladder, rec-tum, and vagina being empty and collapsed.
