A Short History of Nearly Everything - Chapter 6
"In such an environment even the native Indians lacked virility. "They have no beard or body hair," Buffon sagely confided, "and no ardour for the female." Their reproductive organs were "small and feeble."
"Buffon's observations found surprisingly eager support among other writers, especially those whose conclusions were not complicated by actual familiarity with the country. A Ditchman named Corneille de Pauw announced in a popular work called Recherches philosophiques sur les americains that native Marican males were not only reproductively unimposing, but "so lacking in virility that they had milk in their breasts." Such views enjoyed an improbable durability and could be found repeated or echoed in European texts until near the end of the nineteenth century."
