Table V.— MEXICAN BRACHYCEPHALIC CEANIA. 



The Peruvians and Mexicans, with the ancient populations of Central 

 America and Yucatan, constitute the Toltecan family of the two great divisions 

 into which Dr. Morton divided his one American "race or species." The 

 nations lying to the north of those seats of a native civilization were all classed 

 by him into one family of the barbarous tribes, resembling the other in physical, 

 but differing from it in intellectual characteristics. Yet, as we have seen, even 

 Dr. Morton recognized some differences among them ; and Professor Agassiz 

 speaks of their tendency to split into minor groups, though running really one 

 into the other. The following tables, however, will show that the differences 

 are of a far more clearly defined nature, and in realify embrace well-marked 

 brachy cephalic and dolichocephalic forms ; while of these, the latter seems de- 

 cidedly the most predominant. The examples are chiefly derived from the Phila- 

 delphia collection, though with additional illustrations from the Boston cabmets 

 already referred to, as well as from Canadian collections. Table VI, which 

 illustrates the form of head most widely diverging in proportions from the 

 theoretical type, shows in reality the prevailing characteristics of the north- 

 eastern tribes, and could be greatly extenjjcd. The opposite or brachycephalic 

 cranial formation is illustrated in Table VII.
