If in the judgment of the oper-ator the danger entailed upon the fetus by version is too great, natural forces having failed to secure engagement, and if he hastried the forceps cautiously without success, his choice must restbetween symphysiotomy and Cesarean section. The former willbe selected only in isolated instances with most favorable con-ditions if the conjugate is above seven centimeters ; the latter,always in cases of greater contraction than seven centimeters, andoccasionally as a relative indication with a conjugate as large cm. These rules for the treatment of labor obstructed.

This point must always be investigatedcarefully by abdominal palpation, although it is most difficult If the physician has reason to believe that the childis oversized, he must allow himself sufficient latitude to insuredelivery. This advice applies particularly to cases in which 1 1 he relative size of head and pelvis may be determined approximately by themethod of Midler and Schatz. The fetal head i- grasped between the extendedfingers of the physician, and is pressed down steadily and for some time upon thepelvic brim, the direction of the force coinciding with the a\i> of the superior this manceuversucceeds in pressing the head within the pelvis, then natural forceswill surely secure engagement.
