. The six other living children were all born ofthe same mother.* Treatment.—Forceps and version are not, as a rule, successful in the treat-ment of labor obstructed by an obliquely-contracted pelvis unless the degreeof deformity is slight. The induction of premature labor and the perform-ance of Cesarean section are the most successful means of delivery, but theformer should be resorted to only when the distance between the lower edgeof the symphysis pubis and the sacro-iliac joint of the healthy side is notunder 8.5 centimeters. In 20 forceps operations thirteen women died. Theproposition of Pinard to do what he calls ischio-pubiotomy has not met withmuch favor.
