s until he reached the equator, when it would be black.
Proceeding onward, he would gradually become fairer, and on reaching the
end of his journey he would again be pale. His intellectual powers would
vary also, and with them the shape of his skull. His forehead, low and
retreating, would by degrees assume a nobler form as he advanced to more
genial climes, the facial angle reaching its maximum in the temperate
zone, only to gradually diminish as he journeyed toward the torrid, and
to again exhibit under the equator its original base development. As he
continued his journey toward the south pole he would undergo a second
time this series of progressing and retrograding changes, until at
length, as he laid his weary bones to rest in some icy cave in the drear
antarctics,

Multum ille et terris jactatus et alto,

he would be in every respect, save in age and a ripe experience, the
same as at the outset of his wanderings.

Extravagant as this illustration may appear, the professor goes on to
say, philosophically, on the doctrine of the unity of the human race, it
is not so; for what else than such an imaginary prolonged individual
life is the life of the race? And what greater changes have occurred to
our imaginary traveler than have actually befallen the human family?

The facts are patent. Under the equator is found the negro, in the
temperate zones the Indo-European, and toward the pole the Lapp and
Esquimaux. They are as different as the climates in which they dwell;
nevertheless, history, philology, the common traditions of the race,
revelation, point to their brotherhood.

How is it that climate can bring about such modifications in man? Is it
possible that the sun, shining upon his face and his children's faces
for ages, can make their skin dark, and their hair crisp and curly, and
their foreheads low? Or that sunshine and shadow, spring-time and
autumn, summer's showers beating upon him and winter's snows falling
about his path, can make him fair and free? Or that the dreary night and
cheerless day of many changeless arctic years can make him short and fat
and stolid as a seal? Surely not. These avail much; but other
influences, indirect and obscure in their workings, but not the less
essentially climatic, are required. Food, raiment, shelter, occupation,
amusement, influences that tell upon the very citadel and stronghold of
life--and all in their very nature climatic, since they are controlled
and modif
