"Further, the consideration as to the complexion is very decided. Blondes prefer dark persons, or brunettes ; but the latter seldom prefer the former. The reason is, that fair hair and blue eyes are in themselves a variation from the type, almost an abnormity, analogous to white mice, or at least to grey horses. In no part of the world, not even in the vicinity of the pole, are they indigenous, except in Europe, and are clearly of Scandinavian origin."
