NOT EUGENESIC. 41 



It is, however, necessary to inquire wnether the sterility of 

 the Lipplappen depends upon intermixture or upon other 

 causes. The climate of the islands of the Sunda straits is very 

 injurious to Europeans. The Dutch do not perpetuate their 

 race at Batavia; and even without intermarrying with the 

 natives they become sometimes sterile at the second genera- 

 tion. 1 The sterility of the natives may, then, be attributed to 

 the climate. These results, moreover prove, from a verbal com- 

 munication of Dr. Yvan to M. de Quatrefages, that in other 

 Dutch colonies of the Great Indian Archipelago, the Mulattoes 

 are prolific. 2 It is thus not demonstrated that the sterility of 

 the Lipplappen is the result of their hybridity. 



M. de Quatrefages, in order to explain the difference of re- 

 sults produced by the intermixture of the Dutch and the Malays 

 at Java, and other Dutch colonies, supposes that this difference 

 is due to the influence of mediums. This is possible ; but 

 there are other influences which must be taken into account, 

 namely, the numerical proportion of either of the two races 

 who intermarry. Where the Europeans are few in number, 

 the Mulattoes of the first degree are also very few ; those who 

 intermarry between themselves are still less numerous, and the 

 rest ally themselves with the parent stock, chiefly with the in- 

 digenous race, which is preponderating. Where, on the con- 

 trary, the European population is considerable, the Mulattoes 

 of the first degree are sufficiently numerous to constitute a 

 sort of intermediate caste, which, without altogether escaping 

 a recrossing, contract nearly all their alliances with their 

 equals. 3 In the first case, most individuals of mixed blood

3 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 Mu- 

 lattoes 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 ;
