THE MINGLING OF RACES 56 1 



2. Negro-white Crosses in America. Many crosses were made 

 in Brazil between Portugese and negroes, producing a race 

 known as the Metis which is not, in general, characterized 

 by hybrid vigor. Tuberculosis is said to be common among 

 them. They show dissatisfaction with agricultural life and 

 have often proved to be unreHable in matters of trust. Many 

 of them are keenly intelligent but generally are fond of 

 display, rather than of sohd achievement. There has been 

 no social barrier to their progress and they frequently 



. achieve high pohtical office. 



The negro-white hybrid of North America and of the 

 United States results from a cross between two races that 

 resemble each other in stature, though they differ in their 

 proportions, for the negro has longer legs than the white. 

 In the mulatto hybrid the skin color is intermediate; the 

 form of the nose, the prognathism and other facial features 

 are blends of the two races. In body build the mulattoes are, 

 on the average, shghtly superior to the whites, at least this 

 was true of the white and negro soldiers returning from 

 France in 19 19. The negro has, on the average, many 

 advantages in physical quahties over the white. He is much 

 less apt to suffer defects of the spine; and goiter, obesity, 

 deaf-mutism, deafness and most important diseases of the 

 eyes and nasal fossae and throat are less common in his case 

 than among whites. The mulattoes exhibit many of the 

 excellent physical quahties of the negro, but on the other 

 hand, they have an extraordinarily high incidence of tuber- 

 culosis and the venereal disease rate is several times higher 

 than among the whites. The mulatto, however, is more 

 restless, on the whole, than the negro and less easily satisfied 

 with his lot. This is possibly due to a disharmony introduced 

 by the cross. In the United States the colored population 

 has a crime rate of between two and three times that of 

 the white. 



3. Hottentot and Dutch. Hybrids between the Hottentots 

 and Dutch of South Africa have been extensively studied by 

 Professor E. Fischer. He finds that the bastard males show 

 some evidence of hybrid vigor but they are said not to be 

 more variable than the Dutch in respect to stature and some 

 other qualities. However, the bastard stock contained few
