In his comments on tlie foregoing scale of results, Dr. Morton calls attention to 

 the curious fact that the barbarous nations possess a brain larger by five and a 

 half cubic inches than the Toltecans, while, on the otlier hand, the Toltecans 

 possess a greater relative capacity of the anterior chamber of the skull. 



Dr. Morton concludes, from his extended investigations, that the American 

 race differs essentially from all others, not excepting the Mongolian ; that the 

 American nations, excepting the polar tribes, are of one race or species, but of 

 two great families which resemble each other in physical, but difl'er in intellectual 

 characters ; that the cranial remains discovered in the mounds, from Peru to 

 Wisconsin, belong to the same race, and probably to the Toltecan family. 



A careful comparison of the cranial measurements of the Tennessee race 

 with those obtained by Dr. Morton, estaljlishes the fact that the former exceed 

 the Toltecans in the internal capacity of the skull, in the proportion of 81.44 to 

 76.8; the facial angle also is greater in the proportion of 78.8 to 75.35. The 

 largest skull in the Tennessee race exceeded in size, and in the capacity of the 

 brain, the largest American, Ethiopian, Malay, and Mongolian skulls examined 



' The seeming discrepancy in the sums of tliese two series of measurements arises from the fact 

 that only 46 of the 4S skulls measured entered into each series.
