At the time of the discovery, this skull was accompanied by various bones belonging to the body and limbs, which show by their extraordinary bulk that their owners were men of very large size. We have already remarked upon the large size of the men existing in the Stone Age, that is to say, at the time of the first appearance of mankind. Thus, the human type had changed but little since its first appearance on the globe. The settlement of Auvernier, in the lake of Neuchâtel has, as we have before said, contributed two skulls. One belonged to a child about eight years of age, and the other to an adult. The child's skull differs very slightly from the one found at Meilen. It is small, elongated, and has a low and narrow forehead. That of the adult presents the same characteristics, and, in addition, an extraordinary development of the occiput, a feature which is not observable in the former, probably, on account of the youth of the subject. These two skulls seem, therefore, to show that the population of the lacustrine settlements had not at all changed at the beginning of the bronze epoch. A discovery made in the neighbourhood of Sion has confirmed these first ideas. At this spot, in tombs of rough stone, there were found some bodies bent into a contracted position, and accompanied by certain bronze objects. According to MM. His and Carl Vogt, the skulls found at Sion agree tolerably well with those discovered at Meilen and Auvernier; and, in addition to this, the same shape is perpetuated down to our own days in German Switzerland, where it strongly predominates, and constitutes what is called the Helvetic type. The _data_ which have been collected up to the present time are not sufficient to enable us to make any positive assertion respecting the development of the intelligence of man during the bronze epoch. The few skulls which have been recovered are always in an incomplete state, and do not justify us in forming any exact opinion on this matter. But when we are considering the degree of intelligence possessed by our ancestors at this period of man's development, there are things which will enlighten us far better than any fragments of bones or any remains of skeletons; these are the works which have been executed by their hands. The fine arts had already begun to throw out promising germs, industrial skill had become an established fact, agriculture was in full practice, and bronze was made to adapt itself to all the caprices and all the boldest ideas of the imagination. What more can be necessary to prove that man, at this epoch, was already comparatively far advanced in intellectual culture? In concluding our account of the bronze epoch, the question naturally arises whether it is possible to form any estimate of the exact space of time embraced by this period of man's history. We shall endeavour here to give, not the solution of the problem, but merely an idea of the way in which scientific men have entered on the question.
