Whilst he evidently preferred to hunt and eat the larger mammals, man when pressed by hunger did not despise the small rodents, which were, of course, more easily captured. Amongst piles of the bones of horses and stags have been found the remains of martens, hedgehogs, and mice; and from the Thayngen Cave have been taken the bones of more than five hundred bares. In Belgium the water-rat seems to have been considered a dainty, and in the Chaleux Cave alone were found more than twenty pounds’ weight of the bones of this creature, nearly all bearing traces of having been subjected to the action of fire. The remains of birds are rarer, and Broca has remarked that the most ancient hunting implements which have come down to us; those from the Moustier Cave, for instance, were adapted rather to attack animals that would show fight than those that would simply fly or run away. The Gourdan Cave, however, has yielded the bones of the moor-fowl, the partridge, the wild duck, and even the domesticated cock And hen; the Frontal Cave, the thrush, the duck, the partridge, and the pigeon; and in other caves were found the bones of the goose, the swan, and the grouse. Milne-Edwards enumerates fifty-one species belonging to different orders found in the caves of France, and M. Rivière picked up the remains of thousands of birds in those of Baoussé-Roussé on the frontier of Italy.2 The skulls of the mammals bad been opened, and the bones split. Brains and marrow probably figured at feasts as the greatest delicacies. Travellers, whose tales are a help to us in building up a picture of the remote past of our race, relate that the Laplanders, as soon as an animal is killed, break open its skull and devour the brain whilst it is still warm and bleeding. This was probably also the custom amongst prehistoric cave-men. The flesh of animals was not, alas, the only meat eaten, and excavations in different parts of the globe have led to the discovery of traces of the practice of cannibalism which it is difficult not to accept.3
