Note 70 — Chapter I · (continued 2)

Lapouge affirms that "in different historical periods, and over the whole earth, racial differences between classes of the same people are far greater than between analogous classes of different peoples," and that "between different classes of the same population there may be greater racial differences than between different populations" (Pol. Anth. Rev., III, 220, 228). He does not give his definition of class.
