"The monkeys, which are, next to man, the animals by their structure
having the best means to this end, are most excellent imitators, and
there is no limit to the things they can mimic.

"In man, infants which are still of the age when simple ideas are
formed on various subjects, and who think but little, forming no
complex ideas, are also very good imitators of everything which they
see or hear.

"But if each order of things in animals is dependent on the state
of organization occurring in each of them, which is not doubted,
there is no occasion for thinking that in these same animals the
order which is superior to all the others in organization is
proportionally so also in extent of means, invariability of actions,
and consequently in intellectual powers.

"For example, in the mammals which are the most highly organized,
the _Quadrumana_, which form a part of them, have, besides the
advantages over other mammals, a conformation in several of their
organs which considerably increases their powers, which allows of a
great variability in their actions, and which extends and even makes
predominant their intelligence, enabling them to deal with a greater
variety of objects with which to exercise their brain. It will
doubtless be said: But although man may be a true mammal in his
general structure, and although among the mammals the _Quadrumana_
are most nearly allied to him, this will not be denied, not only
that man is strongly distinguished from the _Quadrumana_ by a great
superiority of intelligence, but he is also very considerably so in
several structural features which characterize him.

"First, the occipital foramen being situated entirely at the base of
the cranium of man and not carried up behind, as in the other
vertebrates, causes his head to be posed at the extremity of the
vertebral column as on a pivot, not bowed down forward, his face not
looking towards the ground. This position of the head of man, who
can easily turn it to different sides, enables him to see better a
larger number of objects at one time, than the much inclined
position of the head of other mammals allows them to see.

"Secondly, the remarkable mobility of the fingers of the hand of
man, which he employs either all together or several together, or
each separately, according to his pleasure, and besides, the sense
of touch highly developed at the extr
