I have dwelt upon these deaths and wounds in spite of the inevitable monotony of such a list, not because I wish to bring into prominence the fact that from the earliest times the struggle for existence was fierce and bloody, but because I am anxious to prove that in these remote days an organized and intelligent society had grown up. No one could have survived such wounds as we have described, but for the care and nursing of those around him, such as the other members of his family or of his tribe. The wounded one must have been fed by others for months; nay more, he must have been carried in migrations, and his food and resting-place must have been prepared for him. Moreover, and this is of even yet more importance to our argument, they must have been men able to treat wounds and to set bones. This last fact has been proved beyond a doubt by the discovery of numerous bones with the old wounds completely cicatrized. “In several examples,” says Dr. Prunières, speaking in this connection, “we can make out the fractures set with a neatness which gives us a very high opinion of the skill of the Neolithic bone setters. The setting of one fracture at the lower end of the tibia and of another at the neck of the femur, are not inferior to what we should expect from the most skilful surgeons of the globe.”22 A remarkable fact truly, but one often met with in the most widely separated regions of the earth, the importance of which cannot be overrated, and justifies the giving of a few more details. In 1873 Dr. Prunières, to whom science has reason to be very grateful for his singular discovery, presented to the members of the French Association, in session at Lyons, a human parietal with a rounded piece of bone let into it. This piece of bone was rather larger than a five-franc piece, and the skull into which it had been fixed was found beneath the Lozère dolmen. A large opening, some three inches in diameter, the edges of which were worn smooth, had been made in this skull, and the piece of bone let into it was thicker than the skull itself, as well as different in color, the cranium being dark and the foreign piece of bone pale yellow. It was evident therefore that the two pieces did not belong in life to one person, and that the rounded piece had been cut out of some other skull. The following year Dr. Prunières added fresh details about other rounded pieces of skull that be had discovered let into crania, some of which pieces had evidently been introduced during the life of the patient, who had died under the operation of trepanation, whilst others had been put in after death. Dr. Prunières in every case speaks of _rondelles_ or rounded pieces of skulls, and we prefer to quote him exactly, but as a matter of fact the trepanation was sometimes done with elliptical, triangular, or even pyramidal pieces of bone.
