On the Probable Direful Consequences from the Inter- 
mingling of Human Races. 
It is mind, and mind alone, which constitutes the proud- 
est prerogative of man, whose excellence should be mea- 
sured by his intelligence and virtue. The negro and 
other unintellectual types have been shown to possess heads 
much smaller, by actual measurement in cubic inches, than 
the white races ; and although a metaphysician may dispute 
about the causes which may have debased their intellects, 
or precluded their expansion, it cannot be denied that these 
dark races are greatly inferior to the others of fairer com- 
plexion. Now, when the white and black races are crossed 
together, the offspring exhibits throughout a modified ana- 
tomical structure, associated with sundry characteristics of 
an intermediate type. Among other changes superinduced, 
the head of a mulatto is larger than that of the negro, the 
forehead is more developed, the facial angle enlarged, and 
the intellect becomes manifestly improved. This fact is no- 
torious, viz., that the mulattoes, although but a fraction of 
the population of Hayti, had ruled the island till expelled by 
the overwhelming jealousy and major numerical force of the 
blacks. In Liberia, President Roberts boasts of but one- 
fourth negro-blood; while all the coloured chiefs of depart- 
ments in that infant republic hold in their veins more or less 
of white blood; which component had been copiously infil- 
trated prior to emigration from America into that population 
generally. If all the white blood were suddenly abstracted, 
or the flow of whitening elements from the United States 
to be stopped, the whole fabric would doubtless soon fall into’ 
ruins, and leave as little trace behind as Herodotus’s famous 
_ negro colony of Colchis, or the more historical one of Meroé. 
From the best information procurable, we know that there 
has been a vast deal of exaggeration among colonizationists 
at home about this mulatto colony of Liberia abroad ; nor, 
much as we should be gratified at the success of the experi- 
ment, can we perceive how any durable good can be expected 
from it, unless some process be discovered by which a negro
