inglorious Miltons,” who have lived and died and made no sign of the Divinity within. On the contrary, there have been men of much distinction—of great usefulness to their fellows and to the generations after them, who, naturally considered, were on the dead level of the race, but by their industry, perseverance, and energy have left undying names to posterity. Then, again, circumstances have made men great. An epoch in the annals of a nation—great and stirring events in the life of a people—stimulate and call into exercise qualities and capacities that make men famous, who otherwise would not be heard of. Our own great revolutionary period furnished examples of this, and still later, we have Jackson, Webster, Clay, Calhoun, and their senatorial cotemporaries, who many doubtless think will never be equalled, though their equals in fact are in the senate now, and only need similar circumstances to manifest that equality. The organism of the race—the species—whether human or animal, never changes or varies from that eternal type fixed from the beginning by the hand of God; and men, therefore, are now, in their natural capacities what they always have been and always will be, whatever the external circumstances that may control or modify the development of these capacities. And the brain being the organ or organism of the mind, as the eye is of the sight or the ear of the sense of hearing, it may be measured and tested, and its capabilities determined, with as entire accuracy as any other function or faculty. Not, it is true, as the phrenologists or craniologists contend, that the brain reveals the character of individuals of the same species, but the character of the species itself, and its relative capabilities when contrasted with other races or species of men. This is beyond doubt or question, or will be beyond doubt or question with all those who understand it, and taking the Caucasian as the standard or test, the capabilities of the Mongol, the Malay, the Aboriginal American, or negro, may be determined with as absolute certainty as the color of their skins or any other mere physical quality. The brain of the Caucasian averages ninety-two cubic inches, that of the negro seventy-five to eighty-five inches, while the bodily proportions can scarcely be said to vary. There are great variations among whites as to size—there are giants as well as dwarfs, and quite as great variety in the form,—from the “lean and hungry Cassius,” to the rounded proportions of a Falstaff or Daniel Lambert. But on a Southern plantation of a thousand negroes, sex and age are the only difference or the principal difference that one sees, and a stranger would find some trouble to recognize any other, or at all events to distinguish faces. The brain of the negro corresponds in this respect with the body, and though there are doubtless cases where there is some slight difference, there seems to be none of those wide departures witnessed in these respects among whites.
