The Aryans were those who introduced the use of iron, and with it dominated over and expelled the older races.

If any prehistoric traces of the Semitic races are to be found, they must be looked for in Western Asia or in Africa; they certainly had no settlements in Europe.

Further researches may perhaps at some future time enable us to fix approximative dates to these various migrations. At present we know that men using flint implements lived in the valleys of the Garonne and Dordogne when the climate of the south of France was as cold as that of Lapland, or perhaps Greenland; when the reindeer was their principal domestic animal, and the larger animals of the country belonged to species many of which had ceased to inhabit those regions before the dawn of history. On the other hand, we may assert with certainty that the climate of Egypt has not varied since the age of the Pyramid builders; and there is nothing in the history of either Greece or Italy that would lead us to believe that any remarkable alteration in the climate of these countries has taken place in historic times.

These questions, however, hardly come within the scope of the present work. The men of the Stone age have left nothing which can be styled architecture, unless we include in that term the rude tumuli of earth with which they covered the remains of their dead. It is also extremely uncertain if we can identify any building of stone as belonging certainly to the age of Bronze. All the rude cromlechs, dolmens, menhirs, &c., which usher in the early dawn of civilisation in Europe, belong, it is true to the earlier races, but seem to have been erected by them at a time when the Aryan races had taught them the use of iron, and they had learnt to appreciate the value of stone as a monumental record. This, however, was at a period long subsequent to the use of iron in Egypt and the East, and long after architecture had attained maturity; and its history became easily and distinctly legible in the Valley of the Nile.[[18]]

The great feature in the history of the Turanian races is that they were the first to people the whole world beyond the limits of the original cradle of mankind. Like the primitive unstratified rocks of geologists, they form the substructure of the whole world, frequently rising into the highest and most prominent peaks, sometimes overflowing whole districts and occupying a vast portion of the world’s surface;—everywhere underlying all the others, and affording their disintegrated materials to form the more recent strata that now overlie and frequently obliterate them,—in appearance at least.

In the old world the typical Turanians were the Egyptians; in the modern the Chinese and Japanese; and to these we are perhaps justified in adding the Mexicans. If this last adscription stands good, we have at three nearly equidistant points (120 degrees apart) on the earth’s surface, and under the tropic of Cancer, the three great culminating points of this form of civilisation. The outlying strata in Asia are the Tamuls, who now occupy the whole of the south of India, and all the races now existing in the countries between India and China. The Turanians existed in the Valley of the Euphrates before the Semitic or Aryan races came there. The Tunguses in the north are Turanians, and so are the Mongols, the Turks, and all those tribes generally described as Tartars.

In Europe the oldest people of this family we are acquainted with are the Pelasgi and Etruscans, but the race also crops up in the Magyars, the Finns, the Lapps, and in odd broken fragments here and there, but everywhere overpowered by the more civilised Aryans, who succeeded and have driven them into the remotest corners of the continent.

In Africa they have been almost as completely overpowered by the Semitic race, and in America are now being everywhere as entirely overwhelmed as they were in Europe by the Aryan races, and in all probability must eventually disappear altogether.

Even if the linguist should hesitate to affirm that all their languages can be traced to a common root, or present sufficient affinities for a classification, the general features of the races enumerated above are so alike the one to the other, that, for all real ethnographic purposes, they may certainly be considered as belonging to one great group. Whether nearly obliterated, as they are in most parts of Europe, or whether they still retain their nationality, as in the eastern parts of Asia, they always appear as the earliest of races, and everywhere present peculiarities of feeling and civilisation easily recognised, and which distinguish them from all the other races of mankind.

If they do not all speak cognate languages, or if we cannot now trace their linguistic affinities, we must not too readily assume that therefore they are distinct the one from the other. It must be more philosophical to believe, what probably is the case, that the one instrument of analysis we have hitherto used is not sufficient for the purpose, and we ought consequently to welcome every other process which will throw further light on the subject.
