It has been further sought to show, that, as in Denmark and some 

 other localities, a regular scale of division of the humatile strata into 

 beech, oak, and pine-producing deposits prevails, each respectively 

 coincident with iron, bronze, and stone remaius, that an analogous 

 distribution in time prevailed during the deposition of the extra- 

 European humatile strata. Neither observation nor analogy, however, 

 demonstrates this assumption. In the whole American continent, 

 altiiough we have the chipped flints and celts from Natchez and 

 Chiriqm,f the obsidian knives from Mexico, and the arrowheads from 

 Tierra del Fuego, the copper and gold implements from Peru and 

 Chiriqui, the American mind never devised the plan of smelting 

 iron from the ore, and applying the metalliferous residue to a useful 

 purpose. The so-called " Iron Age " never existed in America. 



The division of human crania into "brachycephalic" and " doli- 

 clioccphalic " originated with the late Professor Eetzius. Like the 

 arbitrary and conventional divisions of other anthropologists into 



ortliognatlious " and "prognathous," it was convenient as afford- 

 ing easy and intelligible descriptive terms for crania of diverse races. 

 As a test of distinction of race, however, it is an insufficient mark of 

 distinction. ^ The supporters of the theory have based on it the fol- 

 lowing classificatioii.;}:
