CRANIA AMERICANA, 



PLATE VI. 



CHIMUYAN. 



In the course of some excavations among the ruins of the Chimuyan city, 

 Dr. Burrough found a skull in admirable preservation. It differs from both the 

 Ancient and Inca Peruvian heads in being of a more oval form, although there is 

 still an obvious inequality betw^een the tw^o sides ; the forehead also is low and 

 retreating, and the width is large between the parietal bones, and the whole head 

 remarkably small.
