The practice of obstetrics, designed for the use of students and practitioners of medicine . resem-ble a beak, because the headsof the femora drive the in-nominate bones inward, whilethe symphysis is held in placeby its muscular internal examination thefinger may be laid in the hol-low of this deformity (). The pubic arch is muchnarrowed and the true con-jugate is very short. Thepromontory of the sacrum isvery prominent, being forceddownward and forward, whilethe tip of this bone and thecoccyx bend so sharply for-ward that the outlet of thepelvis is almost completelyobstructed. The tubera ischiiare displaced outward so thatthe transverse diameter of theoutlet is increased. The pa-tient suffers from dyspneaand cough. The bones be-come very porous and light,containing much cancelloustissue. This tissue containslarge cavities, which may befroin two to four millimetersin length. The pelvis actually collapses and the sufferer always loses markedly in height,—even as much as a foot in some cases,—while, unable even to stand, she is confined to her bed. It.
