The restriction of the discovery of human fossils to Europe is much to be regretted. We have no authority for regarding Europe as the starting point of the species, nor as the theatre of the formation of the primitive races. We should rather seek them in Asia. It was upon the slopes of the Himalaya, at the base of the great central mass, that Falconer hoped to find tertiary man. Assiduous and persevering search can alone verify the prophecies of the eminent palæontologist. This task might be performed by some of the learned officers of the English army, by some of the military surgeons sent out by the great institutions of London. Let us hope that they will set to work; that they will utilize for this end, the leisure they enjoy when on leave in some _sanitarium_ of the Himalayas or Nilgheries. There is every reason to hope that they will enrich science with important and magnificent discoveries. IV. A few general facts, the interest of which will at once be evident, may already be disentangled from details without leaving European soil. We will first establish the fact, that in quaternary ages, man did not present that uniformity of characters, which a recent origin would lead us to expect. The _species_ is already composed of several _races_; these races appear successively or simultaneously; they live side by side; and perhaps, as M. Dupont has thought, the _war of races_ may be traced as far back as this period. The presence of these clearly characterised human groups in the quaternary period, is enough to furnish a strong presumption in favour of the previous existence of man. The influence of very dissimilar and long-continued actions, can alone explain the differences which separate the man of the Vézère in France from that of the Lesse in Belgium. V. In spite of some opinions which were brought forward at a time when science was less advanced, and when terms of comparison were wanting, we may assert that no fossil skull belongs to the African or Melanesian Negro type. The true Negro did not exist in Europe during the quaternary epoch. We do not, however, conclude from this that the type must have come into existence later, and dates from the present geological period. Fresh research, especially in Asia, and in countries inhabited by black nations, can alone decide this point with certainty. Nevertheless, up to the present time, the results of observation have been but little favourable to the opinion of some anthropologists, who have regarded the Negro races as anterior to all others.
