Where extraction by the cranioclast proves difficult owingto non-yielding of the occiput, the cephalotribe, as will benoted, should be substituted. It is to be remembered thatextraction by the cranioclast is possible because, the cranialcontents having been evacuated, traction on the head causes itto be compressed, and thereby diminished by the pressure ex-erted by the pelvic walls. Undue pressure is to be avoided inorder to prevent, in turn, traumatism of the maternal parts. 152 OBSTETRIC SURGERY. (b) Craniotomy of the After-coming Head.—The operationon the after-coming head presents greater difficulties than thaton the before-coming head. The trunk of the foetus havingbeen extracted, it is in the way of the necessary manipula-tions. Only exceptionally, also, will it be possible to electthe desirable point for perforation, this point being the occipito-atloid ligament. Further still, after perforation and excere-bration, if
