Physiologists consider that there are five of these great races, whose characteristics, mental as well as bodily, are distinctly, strongly, and permanently marked.

These characteristics descend by hereditary succession from father to son, and though education and outward influences may modify them, they can not essentially change them.
Compare, for example, the Indian and the African races, each of which has occupied for a thousand years a continent of its own, where they have been exposed to the same variety of climates, and as far as possible to the same general outward influences.

How entirely diverse from each other they are, not only in form, color, and other physical marks, but in all the tendencies and characteristics of the soul! One can no more be changed into the other, than a wolf, by being tamed and domesticated, can be made a dog, or a dog, by being driven into the forests, be transformed into a tiger.

The difference is still greater between either of these races and the Caucasian race.

This race might probably be called the European race, were it not that some Asiatic and some African nations have sprung from it, as the Persians, the Ph[oe]nicians, the Egyptians, the Carthaginians, and, in modern times, the Turks.
