Note 75 — Chapter XI · RACIAL DIFFERENCES ARE PERMANENT
Adrian Collins translation
Ritter, Erdkunde, Asien, vol. i, pp. 433, 1115, &c.; Tassen, Zeitschrift für die Kunde des Morgenlandes, vol. ii, p. 65; Benfey, Ersch and Gruber’s Encyclopädie, Indien, p. 12. A. von Humboldt calls this fact one of the most important discoveries of our time (Asie centrale, vol. ii, p. 639). From the point of view of historical science this is absolutely true.
