All the peculiarities that distinguish him from his race are _sui generis_, without any approximation or resemblance to the white man. So, too, with the latter, and so, too, with all monstrosities in the lower animals. The things that constitute the monstrosity, that separate the creature, or seem to do so, from his own kind, separate him also from other species, whether of men or animals. The eternal gulf, the impassable barrier, the decreed limits fixed by the Creator himself, are never passed. A negro, with the color, or the hair, or the language, or the brain, or the sense of touch, or taste, or sight of the Caucasian, would not be a monstrosity but an impossibility. He might differ very widely from his own race in any one of these things, as we actually witness in the case of Albinos, in fact might retain scarcely any outward resemblance to his kind, and yet exist; but none has ever had, or ever will have, an existence that has any thing in common with the white man, for that would contradict the universal order of God himself. Such being the fact, all that is external or tangible to the sense being thus widely, immeasurably, and indestructibly different from the Caucasian or white man, it is obvious that, in all beyond the outer surface, the same relative differences must exist. It was originally intended to demonstrate this in detail—to show the actual anatomical facts and structural differences in the organs, the tissues, the systems, down to the minutest atom of the bodily structure. It was designed to present the reader with numerous plates, showing all this—the minutest particle, the single globule of blood, even, painted after the employment of the microscope, being sufficiently palpable to the sense, to show that the primordial atoms of the negro structure are as specifically, and relatively as widely, different from the white man’s as the color, the hair, or any of those outward qualities that confront us daily in the streets. But this would have added so much to the expense of the work, as to often place it out of the reach of the day laborer and working man, those who alone, or mainly, need to understand the great “anti-slavery” imposture of our times, and the world-wide conspiracy against their freedom, manhood and happiness, which has so long held them in abject submission to its clamorous pretences of philanthropy and humanity. Nor is it at all essential. A moment’s reflection or consideration is quite sufficient to convince any rational mind that the outward differences must have their counterpart in the entire structure. Of course any thing exceptional—a blemish, a congenital deformity on the surface—has no corresponding relation with the interior, but that which is specific, uniform, and invariable, as the color, the hair, the features, etc., must of necessity pervade the _tout ensemble_ of being, whether human, animal, or vegetable. The apple, pear, peach, etc., have their own specific features externally,
