Geographical knowledge does much to promote the progress of the kindred sciences. The work of Champollion, so brilliantly supplemented by the Vicomte de Rougé and Mariette Bey, has led to the accurate classification of the monuments of Egypt. The deciphering of the cuneiform inscriptions has given us the dates of the palaces of Nineveh and Babylon; the interpretation by savants of other inscriptions has made known to us those Hittites whose formidable power at one time extended as far as the Mediterranean, but whose name had until quite recently fallen into complete oblivion. The rock-hewn temples and the yet more strange dagobas of India now belong to science. Like the sacred monuments of Burmah and Cambodia they have been brought down to comparatively recent dates; and though the palaces of Yucatan and Peru still maintain their reserve, we are able to fix their dates approximately, and to show that long before their construction North America was inhabited by races, one of which, known as the Mound Builders, left behind them gigantic earthworks of many kinds, whilst another, known as the Cliff Dwellers, built for themselves houses on the face of all but inaccessible rocks. Comparative philology has enabled us to trace back the genealogies of races, to determine their origin, and to follow their migrations. Burnouf has brought to light the ancient Zend language, Sir Henry Rawlinson and Oppert have by their magnificent works opened up new methods of research, Max Müller and Pictet in their turn by availing themselves of the most diverse materials have done much to make known to us the Aryan race, the great educator, if I may so speak, of modern nations. To one great fact do all the most ancient epochs of history bear witness: one and all, they prove the existence in a yet more remote past of an already advanced civilization such as could only have been gradually attained to after long and arduous groping. Who were the inaugurators of this civilization? Who ware the earliest inhabitants of the earth? To what biological conditions were they subject? What were the physical and climatic conditions of the globe when they lived? By what flora and fauna were they surrounded? But science pushes her inquiry yet further. She desires to know the origin of tire human race, when, how, and why men first appeared upon the earth; for from whatever point of view he is considered, man must of necessity have had a beginning.
