186 PHYSICAL INVESTIGATION. [PART I. 



they are bad breeders, that the children die young ; and, finally, 

 that the Mulattoes, like the Negroes, are little liable to yellow 

 fever. As to the latter point, we have already shown that it 

 chiefly depends upon acclimatization, and not upon peculiarity 

 of race. With respect to the weakness and mortality of the 

 Mulatto children, it is not yet proved whether or not it is to be 

 attributed to the race, and the fact itself is not yet established. 

 Bachman 1 knew Mulatto families in Carolina and New York 

 who, without any infusion of new blood, were prolific through 

 five generations, and are still so. Lewis 2 expressly denies the 

 sterility of the Mulattoes in Jamaica, and says they are as pro- 

 lific as the black and the white, but they are generally weakly, 

 and their children do not exhibit strong vital powers ; hence 

 Mulatto women prefer marrying Whites, so that the Mulattoes 

 are obliged to marry black women. Hombron 3 remarks, on the 

 sterility of various races, that the white and the native Ameri- 

 can women present the greatest prolificacy ; then come the 

 Negro and the Negress, then Negro and the American woman ; 

 Mulattoes and white women, as well as Mulattoes between 

 themselves, are also very prolific. Mulattoes moreover form, 

 in the northern provinces of Brazil, such a large portion of 

 the population, that their prolificacy cannot be doubted. The 

 vigorous inhabitants of the Fiji Islands are also, by their 

 language and physical constitution, proved to be a mixed 

 people, sprung from Polynesians and Austral Negroes. The 

 people of the Griquas in South Africa have come from inter- 

 mixture of Hottentots, Dutch, and Negroes. 4 The Dutch and 

 Hottentots at the Cape intermarry between themselves, and 

 but rarely with either of the parent stock ; 5 and yet we hear 

 nothing of their sterility ; on the contrary, the offsprings are 

 described as very vigorous. The Rhenish Missionary Journal 6 

 contains a case of a mongrel who was the father of twenty-four 

 children by one wife.
