SUPPLEMENTAL HISTORY OF MAN. 



muscles ; the foramen magnum is larger and farther 

 back, and the apertures for the nerves are larger ; 

 the bony substance is hard, and the whole weight 

 of the skull more considerable ; the organs of sense 

 are more developed, and the narrow forehead, and 

 protruded muzzle give to the negro head a decidedly 

 animal character. We have inserted outline figures of 

 the skull of these three leading varieties of mankind. 



Some of the South African tribes vary a little 

 from the negro conformation of skull. In the head 

 of a Bushman, given by Blumenbach, the cranium 

 is less compressed, the orbits and cheek-bones are 

 wide, and the jaws not prominent. There are other 

 differences, but we scarcely know sufficient of these 

 tribes to class them under any given variety. The 

 origin of the Hottentots, Caffres, Bushmen, and 

 their subdivisions, found at the extremity of South 

 Africa is quite unknown. They exhibit characters 

 strongly approximating to, and discrepancies equally 

 deviating from their negro neighbours. 



The American head is thus characterized : broad 

 cheek-bones, depressed forehead, deep orbits, and 

 the nasal cavity generally large. 



The Esquimaux and Greenlanders, who seem to 

 form a link between the Americans and Mongolians, 

 have broad cheek-bones, large jaws and face, flat- 

 tened nose, the cranium sufficiently ample, but dis- 

 tinguished by a posterior elongation. 



The Carib tribes are conspicuous for a most re- 

 markable depression of the forehead, which defect, 

 like others of the Americans, they increase by arti-
