Reversed Forceps.—When the head is extended across the peri-neum in a posterior position, and lias resisted the various methodsof manual flexion, resort should be had to the operation of re-versed forceps, which is in effect a mere extension of the ancientprinciple that the tips of the forceps should always be directedtoward the leading point. The grasp which the forceps takesupon the extended head when applietl with tlie pelvic curve re-versed is, however, directed so far toward its occipital end thatthe instrument is almost certain to slip after flexion has Ijeenproduced; and it should therefore be an invariable rule that so.

Technique.—The forceps should be placed outside the vulvain the position in which they are to lie when applied to the head;that is, with the transverse axis of the blades at right angles tothe sagittal suture, and with the tips directed bacJvward. If thelock is of the ordinary form, the handle of that blade which wouldbe the left in the ordinary position should be held in the righthand, and, under the guidance of two fingers of the left, shouldbe inserted into the vagina and passed into position as near asjwssible to the occipital end of the head (Fig. 50). The otherblade should be adjusted to correspond with its fellow, and sim-ple traction upon the handles should be made in the direction ABNORMAL LABOR. 217 shown in the figure, all leveiage motions being avoided.
