PLATE XVII.
MEXICAN.
With a better forehead than is usual, this skull presents all the prominent
characters of the American race—the prominent face, elevated vertex, vertical
occiput, and the great swell from the temporal hones upward. Of the particular
tribe to which this individual belonged I am not informed; and I should have
hesitated to present it as a genuine Mexican had I not received, through Mr.
Joseph Smith, late of this , city and now of Mexico, a skull which corresponds
with it in almost every particular, from an ancient tomb at Tacuha. Of the
latter I subjoin, at the end of the following measurements, three diagrams for the
purpose of comparison.
