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 between the two sides; the forehead also is low and
retreating, and the width is large between the parietal hones, and the whole head
remarkably small.
