One of the few crania that can with certainty be said to have belonged to Lake Dwellers of Switzerland was found at Sutz, near Zurich; this skull was fractured at the back. The roundness of the wound, which had been serious enough to cause death, has led authorities to conclude that it was made with one of the formidable pick-hammers, so many of which were found in the lake of Bienne.17 Nilsson speaks of a human cranium pierced with a flint arrow, and of another, both found at Tygelso (Scandinavia), containing a dart made out of the antler of an eland.18 At Chauvaux, at Cesareda, and Gibraltar other crania have been found bearing the marks of mortal wounds, and if we cross the Atlantic we meet with similar instances. Lund tells us that at Lagoa do Sumidouro crania were found pierced with circular tools, whilst near them lay the implements that had caused death.19 At Comox, in Vancouver Island, a skeleton was found with a flint knife imbedded in one of the bones, and at Madisonville (Ohio) another, one of the bones of which was pierced by a triangular stone arrow; whilst beneath a mound in Indiana was picked up a skull pierced by a flint arrow more than six inches long. Excavations at Copiapo (Chili) brought to light the skeleton of a man who had sustained no less than eight wounds from arrows. The force with which they must have been shot is really astonishing; one had broken the upper jaw and knocked out several teeth, penetrating to the brain; and others were still sticking in the vertebrae and ribs.20 In the New as in the Old World man survived many of these horrible wounds, and a skull found under a mound near Devil’s River shows a serious wound inflicted many years before death, and one of the Peruvian crania in the Peabody Museum bears a long frontal fracture, doubtless produced by the violent blow of a club; the five or six fragments still to be made out are, so to speak, solidified, and the wounded man had evidently lived on for many years, thanks apparently to his good constitution alone, for there are no signs of the performing of any surgical operation, such as the removal of the splinters of bone, for instance.21 In 1884 a human vertebra, with an arrow-head imbedded in it, was picked up on the island of Santa Cruz. The apophysis was broken, and the extent of the fracture shows the great force of the blow. The victim evidently died of the wound, for there is no sign of its having been healed.
