These two columns, giving the maximum and minimum capacities, differ so greatly from the second, which shows the average, that they could be of weight only if Mr. Morton had experimented upon a much greater number of skulls, and if he had specified the social position of the individuals to whom they belonged. Thus, for his specimens of the white and copper-colored races, he might select skulls that had belonged to individuals rather above the common herd.[129] But the Blacks and Mongolians were not represented by the skulls of their great chiefs and mandarins. This explains why Dr. Morton could ascribe the figure 100 to an aboriginal of America, while the most intelligent Mongolian that he examined did not exceed 93, and is surpassed even by the negro, who reaches 94. Such results are entirely incomplete, fortuitous, and of no scientific value. In questions of this kind, too much care cannot be taken to reject conclusions which are based upon the examination of individualities. I am, therefore, unable to accept the second half of Dr. Morton's calculations. I am also disposed to doubt one of the details in the other half. The figures 100, 83, and 78, respectively indicating the average capacity of the skull of the white, Mongolian, and negro, follow a clear and evident gradation. But the figures 83, 81, and 82, given for the Mongol, the Malay, and the red-skin, are conflicting; the more so, as Mr. Carus does not hesitate to comprise the Mongols and Malays into one and the same race, and thus unites the figures 83 and 81--by which he receives, as the average capacity of the yellow race, 82, or the same as that of the red-skins. Wherefore, then, take the figure 82 as the characteristic of a distinct race, and thus create, quite arbitrarily, a fourth great subdivision of our species.
