The Creoles, produced by the African with the Spaniard, Italian, and the Southern French, possess considerable durability, but disease and degeneration soon appear when the black mingles with the blood and humors of the more northern nations. With all these mixtures there is a profound characteristic, which constitutes the unity, identity, and reality of the species, which is, continuous fecundity; and this characteristic never varies: it is immutable. The mulattoes live less time than the black or the white race, and their offspring perish readily, and are rarely prolific, except when united with stronger individuals of either primitive type, to which they soon return. XVIII. The blacks have been too degraded to more than conceive of liberty, too debased to think of resistance to the forces that crushed them, and they have neither observed, nor sought for opportunities, to throw off their chains and sweep over the lands, like a destroying element, with the accumulated wrongs of centuries. Yet there were black men among them who were capable of high cultivation. The long contact with the superior white race had recast the faculties of their mind, and had altered perceptibly the rugged contour of their forms and features. The writer observed with wonder in the regiment of black men which formed part of the column of the desperate assault upon Fort Wagner, beautiful heads, whose classic and regular outlines recalled the finest of the antique. We believe with the writer in the "Revue des Deux Mondes," that contact with the white races has given the negro the lines of the Caucasian form, and that the Congo type can disappear or become greatly modified. These changes in the typical form, which we have since observed elsewhere, appear to have taken place sometimes without the admixture of the blood of the whites.
