 It will  be  shown  in  the  sequel  that  the  average  internal  capacity of  the  
 Caucasian or European head  is at least ninety cubic inches;  and it will  be observed  
 that  the  three adult skulls  in  the  preceding  series of  ancient  Peruvians; give an  
 aggregate of two hundred and nineteen cubic inches, or  a  mean of  seventy-three.  
 It will also be observed, that the mean  capacity of  the  anterior  is  about  one half  
 of  that of  the  posterior  chamber, or  twenty-five to  forty-seven;  while  the  mean  
 of  the facial angle  is but sixty-seven degrees. 
 T H E   CHIMUYANS . 
 This  name, Chimù, was  applied  rather  to  a  chief  than  a  territory.  The  
 province  of  the  “ Great Chimù ”  was  very  near  the  present  site  of  Truxillo, in  
 Peru, and its inhabitants  had  attained  a  certain degree of  civilisation  before they  
 were  conquered  by  the  tenth  Inca.  My friend  Dr. M. Burrough,  (now United  
 States Consul at Vera Cruz,) examined the ruins of the Chimuyan city with great  
 care, and  traced  the  remains of  dwellings, walls  and  terraces,  over  an  extensive  
 plot of  ground.*

 America, the reader is referred to the learned Researches of Dr. M’Culloh, Chap  IX.
