[70] 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.
