Ape MARKADLE ANTICIPATION, BIC: 5 
to reject the above-mentioned conclusion is very significant, 
and I give it in his own words (p. 532) :— 
“2. The supposition is contrary to a general law of the 
animal economy, according to which, acquired varieties are 
not transmitted from parents to their offspring, but terminate 
in the generation in which they have taken their rise.” 
The succeeding two sections are allotted to the con- 
siderations contained in paragraphs 1 and 2. 
Section ii. (p. 532) is headed “Instances Showing the 
Permanency of Complexion in Different Races”. ‘The cases 
in which races have completely changed in colour after 
removal to a different climate he explains by a mixture of 
breed ; and points out that “it is easy to find examples of 
an opposite tendency, and to show that the original hue 
Mas been preserved .... Thus he brings forward ie 
instances of the descendants of English colonists in the 
West Indies and Spanish in South America who “remain 
as fair as their European ancestors,’ when there has been 
no intermarriage with other races. ‘‘ That this assertion 
is correct, | am convinced,” he says, ‘‘by the results of re- 
peated inquiries.” In the East the same results are found, 
although the migration of white races into hot climates took 
place at far earlier dates. Thus amongst other examples 
he mentions that of the ‘white or Jerusalem Jews” who 
are believed to have migrated to the Malabar coast in the 
year 490 4.D., and whose living descendants are ‘‘said to 
resemble the European Jews in features and in com- 
plexion ”. 
The converse ‘‘experiment of transplanting black races 
into northern climates” has not been carried on for so long 
a period, but Dr. Prichard points out that ‘‘ several genera- 
tions have produced little or no alteration in the complexion 
of Negroes in the United States and in other temperate 
climates”. It is indeed stated that ‘the domestic Negroes 
who are protected from the heat of the sun by more clothing, 
and who pass their time in sheltered houses, are of a darker 
complexion than the slaves who labour half naked in the 
fields”.
