A trepanned skull was also discovered in a Neolithic sepulchre near Crécy-sur-Morin, where lay no less than thirty skeletons, remarkable for the strongly defined section of the tibiae, whilst around were strewn hatchets, flint knives, bones, stilettos and picks of siliceous limestone with handles made of pieces of stag-horn. The tomb, built of stones without mortar, contained two contiguous chambers separated by a wall, and covered over by a stone weighing more than 1,200 tons. It seems likely that this huge stone had not been moved—it must have been beyond the strength of the makers of the tomb to lift it,—but that the spaces beneath, in which the dead had been placed, had been merely hollowed out. In the covered _Avenue des Mureaux_, of which I have already spoken, were picked up several trepanned crania. The tools, scrapers, and piercers, which had probably been used for the operation, lay near the crania. A Neolithic sepulchre containing three trepanned crania was opened at Dampont, near Dieppe. The operation had been as neatly executed as if it had been performed by one of our most distinguished surgeons. As at Crécy, the sepulchral crypt was divided into two chambers, and the slab between them was pierced with a square opening,24—a fresh example of the curious practice of making openings, of which we have spoken in treating of so many different regions, often apparently completely cut off from communication with each other. Beneath the Bougon dolmen (Deux-Sèvres), in the west of France, was found a skull, and at Lizières in the same department, the skeleton of a tall old man with a dolichocephalic skull and platycnemic tibiæ bearing traces of old wounds badly healed. The bony tissue of the skull was in an unhealthy state and the trepanation had evidently been part of medical treatment. At Saint-Martin-la-Riviére (Vienna), a tomb dating from Neolithic times contained five trepanned crania, on one of which the perforation had been made by scraping. In this tomb was also found a round piece of skull with a hole in it, which had doubtless been used as a pendant. The other objects found in this sepulchre were of a remarkable character, and included hatchets made of coralline limestone, jade, fibrolite, and serpentine, the blades of flint knives, arrows, some feathered, others stalked, some necklace beads, and a number of vases, some apodal, others with flat stands, and nearly all without any attempt at ornamentation. Beneath a dolmen near St. Affrique, M. Cartailhac discovered a skull with two holes in it; one near the bregma, which had been made during life, and the other on a level with the lambda, which had not been made until after death.25 We cannot now note the important conclusions founded on these two perforations, we must be content with adding here that the tomb contained four other skeletons with crania showing no trace of trepanation; the tibiae were platycnemic and the humeri had the
