6. _European Kingdom._ This division Agassiz considers as comprising the entire circumference of the Mediterranean, Persia and Beloochistan. Consequently it embraces very different fauna and flora; it mixes up Aryan, Semitic and Chamitic populations, and takes no account of history. Agassiz himself recognises this fact, and declares that he has only taken into consideration prehistoric times. Since the Quaternary epoch, however, France alone has supported tribes which were tall and dolichocephalic, and others which were short and brachycephalic. Finally, although Agassiz includes the Persians with the Europeans, he leaves out the Hindoos who are ethnologically connected with them, and places them in an entirely different kingdom. 7. _Mongolian or Asiatic Kingdom._ This kingdom encloses all the central portion of Asia, beginning at the Bolor and the Himalayas, and extending as far as Japan. The Mongol is taken as the human type of this vast extent of country. But Agassiz forgets the Aryans of the Bolor, the white Jutchis, the Japanese of the same type, the Aïnos, etc. He unites, therefore, people which belong to at least two extreme types of mankind. 8. _American Kingdom._ Agassiz makes but one kingdom of the whole of America, whilst all zoologists and botanists are agreed in dividing it into at least two great and distinctly characterised centres. He adopts the opinion of Morton, who only admits one human race in America, with the exception of the Esquimaux. Now, since the publication of d’Orbigny’s _Homme Américain_, it is no longer possible to believe in this uniformity. The numerous investigations which have been undertaken upon this question have, moreover, proved still more strongly the multiplicity of races admitted by this traveller. Again, if the human races of America are compared with those of the old world, we shall find, with a few exceptions, a very close connection with Asia, especially in certain populations of Central America: if we compare the fauna and flora, the connection is, on the contrary, closer in North America. These facts are in direct opposition with the theory of Agassiz. 9. _Arctic Kingdom._ This latter kingdom deserves a little more attention than the others. It comprises all the northern regions of the two continents. The southern limit is somewhat arbitrarily fixed by Agassiz at the zone of forests. In no region of the world does man meet with such identical conditions of existence, for all are governed by cold. It would seem, therefore, to be better able than any other to justify the author’s theory, and yet facts agree but very slightly with it.
