The skull of this great Eocene sea-monster, in fact, shows by the narrow and prolonged interorbital region; the extensive union of the parietal bones in a sagittal suture; the well-developed nasal bones; the distinct and large incisors implanted in premaxillary bones, which take a full share in bounding the fore part of the gape; the two-fanged molar teeth with triangular and serrated crowns, not exceeding five on each side in each jaw; and the existence of a deciduous dentition its close relation with the Seals.
The iron struck against the left side of the face, immediately anterior to the inferior maxillary and passed under the zygomatic arch, fracturing portions of the spheroid bone and the floor of the left orbit; it then passed through the left anterior lobe of the cerebrum, and, in the median line, made its exit at the junction of the coronal and sagittal sutures, lacerating the longitudinal sinus, fracturing the parietal and frontal bones, and breaking up considerable of the brain; the globe of the left eye protruded nearly one-half of its diameter.
The transverse arc of the skull, measured from one auditory foramen to the other, across the middle of the sagittal suture, is about 13 inches. The sagittal suture itself is 5.5 inches long. Their principal elevation is disposed so obliquely that I judge them to be due to large frontal sinuses.

SKULL Broad between the ears, forehead flat, but wrinkled when attention is excited. Arch across the skull of a rounded, flattened curve, with a depression up the centre of the forehead from the medium line between the eyes, to half way up the sagittal suture.
The owner then yielded to all our wishes, and he was destroyed with prussic acid. No morbid appearance presented itself in the brain; but, on the inner plate of the right parietal bone, near the sagittal suture, were two projections, one-sixth of an inch in length, and armed with numerous minute spicula. There was no peculiar inflammation or vascularity of any other part of the brain.
It entered the head near the root of the zygomatic arch, about a finger's breadth from the outer corner of the right eye, passed through the head, emerging at the posterior superior angle of the parietal bone, a finger's breadth from the sagittal suture, and about the same distance above the superior angle of the occipital bone.
Ecker, figure of the human embryo; on the development of the gyri and sulci of the brain; on the sexual differences in the pelvis in man; on the presence of a sagittal crest in Australians. Edentata, former wide range of, in America; absence of secondary sexual characters in. Edolius, racket-shaped feathers in. Edwards, Mr., on the proportion of the sexes in North American species of Papilio.
The bosses result from the heaping up of new spongy bone beneath the pericranium, and they may be grouped symmetrically around the anterior fontanelle, or may extend along either side of the sagittal suture, which appears as a deep groove the "natiform skull."
"The extreme length of the skull is 7.7 inches, and as its extreme breadth is not more than 5.25, its form is decidedly dolichocephalic. The transverse arc from one auditory foramen to the other across the middle of the sagittal suture measures about 13 inches.
