Mulattoes of the latter kind exist in large numbers in the greater part of the Antilles, South America, Central America, Mexico, Mauritius, Bourbon, and Senegal. All these countries have been colonised by the French, Spaniards, or Portuguese. The Mulattoes born there are fecund in their intermixture with the parent stock, as the Mulattoes of Germanic origin; they are also prolific between themselves, at least in the first generation. Are they equally prolific in their direct alliances as in their mixed ones? Are their children arriving at maturity as the others? And finally, when these children intermarry, are they and their descendants prolific? These questions are yet unanswered. They can only be solved after a long series of observations collected by men of science; not by travellers who view the populations superficially, but by close observers, and principally by physicians resident in these localities. In the mean while, here is another passage from the work of Prof. Waitz, quoted by him from Seemann.[33] “The Mulattoes of the Negroes and Whites at Panamá are prolific between themselves, but their children are brought up with difficulty; whilst the families of the pure races produce less children, which however arrive at maturity.” The Europeans of Panamá are of Spanish origin. The prolifickness of the Mulattoes of the first degree is clearly indicated in this passage, but doubts may be entertained as to the fecundity of their descendants. The intermixtures of Negroes and Europeans are not the only ones the results of which exhibit defects to the observers. “The Mulattoes,” says M. Boudin,[34] “are very often inferior to the two parent stocks, both in vitality, intelligence, or morality. Thus the Mulattoes of Pondicherry, known by the name of Topas, exhibit a mortality not only more considerable than that of the Indians, but greater than the Europeans, though the latter are considerably shorter lived in India than in Europe. Positive documents on this point have been published in the _Revue Coloniale_. So much as to the vitality. “In Java, the Mulattoes of the Dutch and Malays are so little intelligent that they could never be employed as functionaries. All Dutch historians are agreed upon this point. This much for their intelligence. “The Mulattoes of Negroes and Indians, known by the name of _Zambos_ in Peru and Nicaragua, form the worst class of citizens. They compose four-fifths of the prison population. This fact, already mentioned by Tschudi,[35] has recently been confirmed by Squier. So much as regards morality. “There are, however, certain physical qualities which may be acquired by the intermixture of races. Such are pathological immunities. The Mulattoes of the West Indies are, like the Negroes, exempt from the yellow fever.”
