Obstetrics : the science and the art . of the face were removed, the remain-der of the cranium would be oviform; as Ihave on different occasions shown it to be,by removing those bones in presence of myclass at the Medical College. In looking at the head from above down-wards, as in Fig. 29, the bones of the faceare out of sight, and the cranium is evi-dently egg-shaped, the greater pole being at the occiput, while thelesser is at the forehead. The foetal head (Fig. 30) is copied with the camera from a east of afoetal head, and gives a proper idea of the true form when coveredwith its integuments: the child perished in the labor, its head beingtoo large to pass through the straits without the aid of the forceps. The longitudinal diameter of this oviform skull has, by most computed at four inches, and its conjugate at three inches and ahalf; both of which calculations are considerably under the mark oftruth, as 1 have found by careful measurement. The bones that enter into the composition of the skulk excepting6. b2 PRESENTING PARTS — THE HEAD. the face pieces, are the os occipitis, the two ossa parietalia, the osfrontis. the two ossa temporum, and the sphenoides. These are the- that make up the principal bulk of the object, for the face bonesdo nut add very considerably to the magnitude of the mass. Fig. 29. Fig. 30.
