_Prehistoric Types of the Human Race_.--The earliest record of human
life yet discovered is the _Pithecanthropus Erectus_ (Trinil), the
apelike man who walked upright, found in Java by Du Bois, about the
year 1892. Enough of the skeletal remains of human beings were found
at this time to indicate a man of rather crude form and low brain
capacity (about 885 c.c.), with possible powers of speech but with no
probably developed language or no assumption of the acquaintance with
the arts of life.[4]

The remains of this man associated with the remains of one other
skeleton, probably a woman, and with the bones of extinct animals, were
found in a geological stratum which indicates his age at about 500,000
years. Professor McGregor, after a careful anatomical study, has
reproduced the head and bust of Pithecanthropus, which helps us to
visualize this primitive species as of rather low cultural type. The
low forehead, massive jaw, and receding chin give us a vision of an
undeveloped species of the human race, in some respects not much above
the anthropoid apes, yet in other characters distinctly human.

There follows a long interval of human development which is only
conjectural until the discovery of the bones of the Heidelberg man,
found at the south of the River Neckar. These are the first records of
the human race found in southern Europe. The type of man is still
apelike in some respects, but far in advance of the Pithecanthropus in
structure and general appearance. The restoration by the Belg
