Having given the number of the European population of Batavia, Havorinus adds, “Among the Europeans figure also such as are born from European parents, among whom females form the great majority” (Havorinus, _Voyage par le Cap de Bonne-Espérance et Samarang, et traduit du Hollandais_, chap. viii, t. II, p. 283. Paris). It seems thus that the influence of climate produces some modification in the generative powers of Europeans, rendering them less apt to procreate males even with the women of their own race. This modification may be transmitted to their descendants by intermixtures. The fact of Havorinus should, however, be verified.

[40] In America, the intermixture between Whites, Negroes, and Mulattoes passes differently. The Mulattoes are slaves like the Negroes. A large number of Mulatresses become the concubines of the White: and the Mulattoes are mostly obliged to confine themselves to Negro women. There are, then, relatively few unions between Mulattoes of the same blood. The abolition of slavery neither could, nor will for a long time, sensibly modify this state of things. The prejudice against colour will not soon become effaced; and many Mulatto women prefer to be the mistresses of Whites to being the wives of Mulattoes. In the East Indies, the prejudice of colour does not exist. The Whites are merely considered as an aristocratic class; the Malays are free as well as the Mulattoes, they have always been so. The Mulattoes are proud of having in their veins European blood, as, in our own country, certain citizens are proud of their aristocratic alliances. They form thus, _in the centres of the population_, a sort of intermediate caste between the Whites and the natives. [41] It is necessary to mention, that the expression of the first degree designates here not merely the individuals issued from the first intermixture, but also the descendants of unions which they form between themselves.
