1. _Polynesian Kingdom._ We shall see presently that it is impossible to regard Polynesia as a centre of human appearance. This region has been entirely peopled by migration from the Indian Archipelago, the history of which has been partly preserved. The first kingdom of Agassiz must be struck out as far as we are concerned; it is an exclusively animal and vegetable centre. Agassiz, moreover, though he supports it in the text and upon the map, does not assign it a place in the illustrated table, in which he sums up his ideas. 2. _Australian Kingdom._ Agassiz includes New Guinea in this kingdom. He thus destroys the homogeneity of the mammalogical fauna. At the same time he unites the several human races of Australia with the Negrittoes and Papuans. This alone destroys all unity of type. 3. _Malay or Indian Kingdom._ This kingdom comprises India, the Malay Archipelago, and the Andaman Islands. Now, anterior to the Aryan conquest, Yellows and Blacks lived in India. The latter are still found in a pure state in the peninsula of Malacca, and in the Andaman Islands; Malaysia presents a perfect mixture of most different races, from the White to the Negro. The Malays, properly so-called, are much rather a population levelled by the action of Islamism, than a race in the true sense of the word; they present in a high degree the characters of intercrossing. All these facts protest against the idea of making these regions a centre of human appearance. 4. _Hottentot Fauna._ Agassiz abandons the expression kingdom in speaking of the south of Africa, without giving any reason for the change. Whatever the cause may be, this is one of the least unfavourable regions for the application of his theory. From a geological or botanical point of view, South Africa constitutes a veritable centre. The Bosjesman and the Hottentot might be considered as the characteristic human type. But the Negroes of Delagoa and the Kaffirs still protest against this partial coincidence. 5. _African Kingdom._ This region is considered by Agassiz to comprise the rest of Africa, with the exception of the shores of the Mediterranean. He adds Madagascar and the southern half of the Arabian peninsula. Now, from a mammalogical point of view, Madagascar forms a little centre of itself, whilst the human population is very mixed. The Hovas are very slightly modified Malays, and the languages of the Sacalaves themselves indicate relations with the Malayo-Polynesians. As to the continental portion of the kingdom, it is enough to remark that it includes Negroes, Abyssinians, Arabs, etc. History, as well as the present state of things, protests against the connection made in this case by the author.
