Three years after his injury he was in every respect well. Fraser mentions an instance of a boy of fifteen who was caught in the crank of a balance-wheel in a shingle-mill, and was taken up insensible. His skull was fractured at the parietal eminence and the pericranium stripped off, leaving a bloody tumor near the base of the fracture about two inches in diameter.
The rock-shelter of Entre-Roches is supposed to date from Paleolithic times, and if it were certain that there has been no displacement of the soil on which the parietal was found, it is to be concluded that trepanation was practised in the Quaternary period when man was living amongst the large extinct pachydermata and felidae.
We must mention yet one more discovery which it will not do to omit. A human parietal with a piece missing that had evidently been taken out, was found beneath the rock-shelter of Entre-Roches near Angouleme. The skull bore very evident traces of the performance of an operation which may or may not have been executed during life.
And no investigator of homologies doubts that a considerable number of the bones which form the skull of any osseous fish are distinctly homologous with the cranial bones of man. The occipital, the parietal, and frontal, the bones which surround the internal ear, the vomer, the premaxilla, and the quadrate bones, may be given as examples.
The bosses disappear in time, but the skull may remain permanently altered in shape, the frontal and parietal eminences appearing unduly prominent.
The medical man in attendance has kindly given me a copy of his certificate, which I inclose. You will see that the remains are identified by the description of a small silver plate on the right parietal bone of the skull. I need hardly add that all the information I can give you is willingly at your service. She mentions, poor soul, something which she had to ask of you.
In no case, however, are either the frontal or the temporal sulci the earliest. As a rule the occipito- parietal is the earlier of the two. At the latter part of this period, another sulcus, the "posterio- parietal," or "Fissure of Rolando" is developed, and it is followed, in the course of the sixth month, by the other principal sulci of the frontal, parietal, temporal and occipital lobes.
Besides Doreen had her way to make like any other girl, and no one can deny the difference between the son of an exceptionally wealthy and indulgent parent and the same son after the parental wealth has exploded and the parental brain has been drilled with a .450 calibre bullet discharged at a range of two inches from the frontal bone and making a somewhat unsightly exit by way of the parietal.
When I was at home, they were as near to me as they are to you. The arguments of the League and its leader are known to all friends of free trade. The gaieties and genius, the political, the social, the parietal wit of "Punch" go duly every fortnight to every boy and girl in Boston and New York.
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.
