islands, where the latter Mulattoes do not thrive, arc rnoro 

 unhealthy than Java. There seems, therefore to result, from 

 the facts quoted by Waitz, that the Malay-Chinese thrive 

 where the Chinese are few in number, and that they decay 

 where the Chinese are numerous ; that is to say, that the 

 fecundity of the hybrid population augments in proportion as 

 the conditions favourable to a return crossing with the Malay 

 race are present. This amounts to the same thing, namely, 

 that the Mulattoes of the second, third, and fourth degree are 

 more prolific than those of the first, which certainly corresponds 

 with the laws of hybridity among animals. These facts, how- 

 ever, require to be vei'ified and completed before they can serve 

 as a basis to arrive at a definite conclusion. 1 



These examples of the Mulattoes of Malasia, which we 

 accept with reserve, tend to demonstrate that the results of 

 intermixture do not exclusively depend on the degree of 

 proximity of race ; for there is certainly a less zoological 

 distance between the Chinese and the Malays, and between 

 the Malays and the Dutch, than between the African Negroes 

 and the South Europeans. Yet the Mulattoes of the French, 

 Portuguese, and Spanish colonies seem gifted with a much 

 greater prolificacy than the Dutch or Chinese Mulattoes of 

 Malasia. It is besides known that in Mexico and South 

 America the union of the indigenous population between the 

 Portuguese or the Spaniards has, in many localities, produced 

 Mulattoes, the race of which seems to perpetuate itself. 2 



1 Mr. Gutzlaff, tlie Chinese missionary, has been struck with the little fecun- 

 dity of the Mulattoes of Canibojia, the offspring of the native race and the 

 immigrant Chinese. Cambojia is situated south-west of Siam, south of Anain, 

 between 10 and 14. " It is remarkable," he observes, " that the marriages 

 of native females with the Chinese are productive at the first generation, 

 but become gradually sterile, and completely so at the fifth generation. I 

 have seen many such cases ; but I cannot explain such a degeneration be- 

 tween nations so similar in physical conformation, and their mode of life. 

 If it were not so, the Chinese race ought to become predominant, and absorb 

 the native race in a few centuries. Such has not been the case, and the in- 

 numerable immigrants which China pours in appear scarce among the popu- 

 lation. (Gutzlaff, Geography of the Cochin-Chinese Empire, Journal of the 

 Royal Geographical Society of London, vol. xix, p. 108, London, 1849.) 



2 It is unknown what is the degree of intermixture in the hybrid popula- 

 tions of Mexico and South America ; the observations relative to these cross- 

 ings are extremely difficult to collect, for the variation of Mulattoes of dif- 

 ferent degrees is not so apparent as in the Mulattoes, Quadroons, etc., of 

 Negroes and Em-opeans. With regard to colour, hah-, shape of the cranium,
