Closely related to the Manchus (of the same stock says Sir H. H. Howorth, the distinction being purely political) are the _Dauri_, who give their name to the extensive Daur plateau, and formerly occupied both sides of the Upper Amur. Daur is, in fact, the name applied by the Buryats to all the Tungus peoples of the Amur basin. The Dauri proper, who are now perhaps the best representatives of the original Manchu type, would seem to have intermingled at a remote time with the long-headed pre-Mongol populations of Central Asia. They are "taller and stronger than the Oronchons [Tungus groups lower down the Amur]; the countenance is oval and more intellectual, and the cheeks are less broad. The nose is rather prominent, and the eyebrows straight. The skin is tawny, and the hair brown[628]." Most of these characters are such as we should expect to find in a people of mixed Mongolo-Caucasic descent, the latter element being derived from the long-headed race who had already reached the present Mongolia, Manchuria, Korea, and the adjacent islands during neolithic times. Thus may be explained the tall stature, somewhat regular features, brown hair, light eyes, and even florid complexion so often observed amongst the present inhabitants of Manchuria, Korea, and parts of North China. But no admixture, except of Chinese literary terms, is seen in the Manchu language, which, like Mongolic, is a typical member of the agglutinating Ural-Altaic family. Despite great differences, lexical, phonetic, and even structural, all the members of this widespread order of speech have in common a number of fundamental features, which justify the assumption that all spring from an original stock language, which has long been extinct, and the germs of which were perhaps first developed on the Tibetan plateau. The essential characters of the system are:--(1) a "root" or notional term, generally a closed syllable, nominal or verbal, with a vowel or diphthong, strong or weak (hard or soft) according to the meaning of the term, hence incapable of change; (2) a number of particles or relational terms somewhat loosely postfixed to the root, but incorporated with it by the principle of (3) vowel harmony, a kind of vocal concordance, in virtue of which the vowels of all the postfixes must harmonise with the unchangeable vowel of the root. If this is strong all the following vowels of the combination, no matter what its length, must be strong; if weak they must conform in the same way. With nominal roots the postfixes are necessarily limited to the expression of a few simple relations; but with verbal roots they are in principle unlimited, so that the multifarious relations of the verb to its subject and object are all incorporated in the verbal compound itself, which may thus run at times to inordinate lengths. Hence we have the expression "incorporating," commonly applied to this agglutinating system, which sometimes goes so far as to embody the notions of
