I am also aware that the notion prevails generally in the United States that the mulatto has no vitality of race; that after three or four generations he dies out. This idea, I believe, finds its strongest advocates among the slaveholders and the readers of De Bow’s “Review,” and possibly it may be correct when applied to the colder latitudes; but I have no reason to think it is so in or near the tropics. Moreau de St. Mery, in his minute “Description of the French part of St. Domingo,” says, with respect to the vitality of the mulatto, which term includes all persons of color, however slight, of mixed European and African descent: “Of all the combinations of white and black, the mulatto unites the most physical advantages. It is he who derives the strongest constitution from these crossings of race, and who is the best suited to the climate of St. Domingo. To the strength and soberness of the negro he adds the grace of form and intelligence of the whites, and of all the human beings of St. Domingo he is the longest lived.... I have already said they are well made and very intelligent; but they are as much given to idleness and love of repose as the negro.” Hermann Burmeister, Professor of Zoölogy in the University of Halle, who spent fourteen months, in 1850-51, in studying at Brazil the “Comparative Anatomy and Physiology of the American Negro,” speaks thus of the Brazilian mulatto: “The greatest number of the colored inhabitants of Brazil are of the negro and European races, called mulattoes. It may be asserted that the inferior classes of the free population are composed of such. If ever there should be a republic, such as exists in the United States of America, as it is the aim of a numerous party in Brazil to establish, the whole class of artisans would doubtless consist of a colored population. * * * Already in every village and town the mulattoes are in the ascendant, and the traveller comes in contact with more of them than of whites.” There is nothing in these extracts, or in the essay from which they are taken, to indicate that the Brazilian mulatto is dying out. These are the observations of a patient investigator and man of science, and they have the more value, inasmuch as they were not set down to support any particular theory. The Professor speaks elsewhere in high but qualified terms of the moral and intellectual qualities of the mulatto, coming to conclusions similar to those of Moreau de St. Mery, except that he does not accuse them of indolence. The author of “Remarks on Hayti and the Mulatto,” whose experience as a merchant I have mentioned, further says: “This race, if on the white side it derives its blood from either the English or French stock, possesses within itself a combination of all the mental and physical qualities necessary to form a civilized and progressive population for the tropics, _and it is the only race yet found of which this can be said_.”
