Invites CD and Mrs Darwin to stay at his home if they plan to attend the International Congress of Anthropological Sciences, 16–21 August, and the seventh session of the French Association for the Advancement of Science, 22–9 August.

Thanks CD for compliments on the first part of his "discours",

but the later part was critical of natural selection. Nevertheless, CD should see him not as a systematic adversary, but in the camp of Quatrefages de Bréau and Milne-Edwards.

Announces that the Société d’Anthropologie de Paris has elected CD a Foreign Associate.
