The brain begins in a human being in embryonic life, as it begins in
the animal kingdom, void of the convolutions which are seen in its
maturity,--beginning as a small outgrowth from the medulla oblongata,
which after the second month extends into three small sacs of nervous
membrane inclosing cavities, making a triple brain, such as exists in
fishes, which are the lowest type of vertebrated animals,--animals
that have a spinal column or backbone.

From this condition, the fishy condition of the nervous system of the
embryo human being at the end of the second month, there is a regular
growth which develops in the embryo the forms characteristic of higher
orders of animals in regular succession,--fishes, reptiles, birds, and
quadrupeds or mammalia, monkeys, and man.

This is the same order of succession which geologists assign to the
development of the animal kingdom, the higher species coming in after
the lower; and if every human being, instead of developing at once,
according to the human type, is compelled to pass through this regular
gradation of development, is it not apparent that the lower for
