The natives of many of the kingdoms and isles of _Asia_, are found to have their _corpus mucosum_ black.

Those of _Africa_, situated near the line, of the same colour.

Those of the maritime parts of the same continent, of a dusky brown, nearly approaching to it; and the colour becomes lighter or darker in proportion as the distance from the equator is either greater or less.

The Europeans are the fairest inhabitants of the world.

Those situated in the most southern regions of _Europe_, have in their _corpus mucosum_ a tinge of the dark hue of their _African_ neighbours: hence the epidemick complexion, prevalent among them, is nearly of the colour of the pickled Spanish olive; while in this country, and those situated nearer the north pole, it appears to be nearly, if not absolutely, white.
These are facts[084], which anatomy has established; and we acknowledge them to be such, that we cannot divest ourselves of the idea, that _climate_ has a considerable share in producing a difference of colour.
