Note 104 — Chapter XIII · THE HUMAN RACES ARE INTELLECTUALLY UNEQUAL; MANKIND IS NOT CAPABLE OF INFINITE PROGRESS
Adrian Collins translation
D’Orbigny tells how Indian mothers love their children to distraction, and take such care of them as to be really their slaves. If however the child annoys the mother at any time, then she drowns him or crushes him to death, or abandons him in the forest, without any regret. I know no other example of such an extraordinary change (D’Orbigny, L’Homme américain, vol. ii, p. 232).
