456 EXPLANATION OF THE PLATES. 



degree. There is no very striking difference between the 

 skulls of the west and east coast of Africa. Those of 

 Oriental Negroes, and even of Horafouros, who are not an 

 unmixed race, have the same typical structure, though more 

 debased ; the Tasmanian being the lowest, with perhaps the 

 exception of the Bushman. 





PLATE III. 



Of the beardless type, may be observed the shorter and 

 more quadrangular cranial form, with still some facial 

 protrusion ; and, in the most northern partially mixed races, 

 the very contracted occiput is remarkable. 



PLATE IV. 



Shows the regular oval form of the most intellectual 

 type : more breadth of forehead ; prolonged expansion back- 

 wards, and nearly vertical facial angle. The regular dome, 

 as seen in the finest races of mankind ancient Egyptians, 

 Hebrews, Greeks, Circassians, and Arabs. In most Euro- 

 pean, a slight modification from a Finnic source may be 

 traced. 



PLATE V. 



Represents two heads of princes, taken from Bactrian 

 coins, one evidently a portrait of true Mongolic sovereigns, 

 whose forms do not occur in Western High Asia till after 

 the Christian era, and the other of Hunnic or Finnic Kings, 

 likewise of Bactria, who have the occiput flattened like 

 No. 3, taken from a Mexican bas-relief, and features of 

 the same class as those of occasional high-nosed American 

 Indians of the present day, like No. 4.
