40 INTERMIXTURE OP CERTAIN RACES 



of citizens. They compose four-fifths of the prison popula- 

 tion. This fact, already mentioned by Tschudi, 1 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 patholo- 

 gical immunities. The Mulattoes of the West Indies are, like 

 the Negroes, exempt from the yellow fever." 



The fecundity of Mulattoes is not touched in this passage, 

 not having been the subject of discussion. The question 

 merely was whether the prevalent opinion, that intermixture 

 of improved races physically, intellectually, and morally, was 

 in accordance with well observed facts. Hence, M. Boudin 

 confined his observations to the limited intelligence exhibited 

 by the Mulattoes issued from the union of the Dutch of Java 

 with the Malay women. But in his Treatise on Medical Geo- 

 graphy, , 2 he expresses, with regard to the Mulattoes, an opinion 

 that they are not productive beyond the third generation. 

 This fact, announced by Dr. Yvan, which is confirmed by other 

 testimonies, has not been -contested. Waitz borrows from 

 Graf Gortz some particulars which are not without interest. 



" The Lipplappen," he says (this is the name of the Mulat- 

 toes of Java), ff do not breed beyond the third generation. 

 Flabby and weakly, they become developed up to the fifteenth 

 year, when the development is arrested. At the third genera- 

 tion, girls only are born, which are sterile. 3 This phase of 

 sterility is very curious, and deserves well the attention of 

 physiologists." 



1 Dr. Tschudi adds, " considered as men, the Zambos are far inferior to the 

 pure races :" Travels in Peru, London, 1847. G. Pouchet, De la Plurality des 

 Races Humaines, p. 137. Paris, 1848.

3 Graf Gortz, Beise, bd. iii, p. 288. Waitz, Anthropologic, bd. i, p. 297. I 

 find in the voyage of Havorinus a passage which may, perhaps, explain the 

 singular fact pointed out by Graf Gortz. 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-Esperance 

 et Samarang, et traduit du Hollandais, chap, viii, t. n, p. 283. Paris). It 

 seems thus that the influence of climate produces some modification in the 

 generative powers of Eiu-opeans, rendering them less apt to procreate males 

 even with the women of their own race. This modification may be trans- 

 mitted to their descendants by intermixtiu'es. The fact of Havorinus should, 

 however, be verified.
