THE HUMAN SPECIES. 147 



head there could not be much space for the anterior 

 lobes of the brain. The orbits were exceeding strong, 

 with a somewhat elevated ridge, and the bones of the 

 face harder and more solid than those which were pro- 

 duced for comparison. Dr. Lund likewise observed the 

 incisor and molar teeth of adults to be worn to flat 

 crowns a character which occurs also in some ancient 

 Egyptian jaws, and in heads of Guanche mummies. 



Here, again, we have characters so marked and de- 

 cisive, that if the case were applied to a lower animal, 

 sjstematists would not hesitate to place it as a separate 

 species ; and the comments of physiologists, who refuse 

 their assent, not being in harmony with the admitted 

 definitions, are more specious than convincing. It ap- 

 pears, that the nation to which this form of head was 

 peculiar, although with all the signs of very low intel- 

 lectual faculties, had nevertheless made advances in 

 civilization, which several of the Asiatic abnormal 

 tribes have never even attempted to acquire. They 

 built houses, of large stones, in a pyramidal form, 

 having an upper floor ; and judging from certain re- 

 mains of their implements, and the contents of their 

 graves, they were peaceable beings, most likely under 

 the controul of superiors, not of the same stock, even 

 from periods anterior to the formation of the Inca 

 system of civilization. Mr. Pentland, we believe, first 

 brought this singular race into notice, from skulls dug 

 up near the shores of Lake Titicaca, Dr. Lund found 

 others, even in a fossilized state, in the interior of 

 Brazil. They were discovered in limestone crevices, in
