in the West Indies produce children of West Indian colour and 

 physiognomy, produce in Europe, children of European colour 

 and physiognomy. The white Creoles in Peru originating from 

 the North of Spain lose their ruddy complexion in the second 

 generation, the whiteness of the skin becomes sallow. 1 Red hair 

 and blue eyes disappear from the family in succeeding genera- 

 tions. (Sucle retroceder en las generaciones siguientes sacando

The changes which the Negroes undergo in America will be 

 treated of in the sequel, as they are not so much owing to the 

 climate as to the change of habit, diet, and their intercourse 

 with a more intellectual race. Here it may be merely observed 

 that though some instances have been quoted 2 of Negroes 

 who, transplanted to the north, have become gradually lighter, 

 and ultimately white, they are isolated cases, like that men- 

 tioned by De la Salle, 3 of a French lady whose hair changed in 

 the East Indies from dark brown (perhaps dyed ?) to a bright 

 red. As regards the Botokudes, among whom in their own 

 country there are white men with red cheeks, although they 

 live under 20 south lat., it scarcely can excite surprise that 

 they become in Europe white in winter, as mentioned by 

 Prince Max. 4 Blumenbach, and Hunter before him, 6 believed 

 that it takes a longer time for a Negro to grow white than for 

 a European to become black. Skin affections must be taken 

 into consideration before admitting the above cases as proofs 

 either way. A morbid affection was probably the cause in an 

 instance related by Anderson, 5 of a Negro whose black shining 

 skin became in a very cold night of a pale ash-grey colour. 

 Prichard r speaks of Tuaryks, who, when living alone in an oasis, 

 became gradually, as regards hair and features, negro-like ; 

 but the metamorphosis has been lately invalidated by Barth,
