Martin Delany presents a treatise which proposes to solve, as well as to show the first steps in the progress of civilization, the origin and institution of letters and literature. On the delicate subject of the integrity of the races, he proposes that the pure races are indestructible. As in the science of chemistry, the two extremes, saccharine and acid, the most intense sweetness and the most intense sourness are produced by the same material and essential properties. So is it, in the substance and science of animal chemistry in the human family in relation to color or complexion of the skin. The two extremes of color, from the most negative white, "including every possible variety of tint", up to the blackest, are all produced by the same material and essential properties of color.
