This last point is one of such supreme importance that it seems well to strengthen it by additional testimony. Says the renowned Cesare Lombroso, in his "_L'Uomo Bianco e L'Uomo di Colore_" (1892), p. 28: "The development of the African baby is altogether different from ours. In its first days it does not show the dark color of the adult; the sutures of the head, which with us close up only late in life, with it ossify speedily, as in idiots and monkeys, and the anterior sooner than the posterior. Also its face becomes projecting and prognathous only after the first dentition; and only after the thirteenth year its head is seen to grow longer and its skin to grow darker. The same may be said of the mental (_morale_) development; for the Negro, precisely like the monkey, shows himself very intelligent up to puberty; but at that epoch, when our intellect spreads its wings for more daring flights, he stops and turns backward..." This profoundly significant arrest of development in the Negro is equally observable in school and out of it. Among many witnesses, hear one of the most unexceptionable, J. M. McGovern, in a symposium in the _Arena_ (Vol. 21, p. 439): "My experience has shown me that, while at the start a negro child often shows ability quite equal to that of a white child at the same age, yet if the two children, one white and one coloured, each of average intelligence, are kept in the same class, in a short period the white child far outstrips the negro--at least in all those studies where diligent application and depth of thought are necessary for success." This testimony seems particularly valuable, since it is based solely on "experience" and is plainly independent of any doctrine concerning cranial sutures. In the work already cited, Lombroso mentions several other minute yet important particulars in which the Negro anatomy diverges from the Caucasian toward the simian, but sufficient have been adduced. It may be replied that each and every one of these divergences may be found here and there among Caucasians. This is true, but the reply is no answer. All sorts of reversions to lower type are to be met with in higher species, but this by no means negatives the fact that some species are more and some are less developed. The well-formed type still exists in spite of the occasional malformations. Besides, it is not the presence of any single indication on which our argument is grounded, but the simultaneous presence of a great number of indications. It is these in their entirety that distinguish the Negro so notably, and remove him toward the anthropoids; and over against this fact the occasional aberrations among the Whites have no argumentative weight whatever.
