Thanks WED for his letter of 20 December 1875. Is surprised and delighted by the support from WED and CD for the Index.

Wishes to inform CD that, contrary to CD’s impression, natural selection is widely accepted in U. S. by educated men; encloses copies of his lectures, papers, and the Index.

Thanks CD for interest in FEA’s work and for money for Index. Sends 1870 volume of Index.

Praises CD’s services to free-thought.

Asks for CD’s view of the influence of his theory on religion, to use in lecture.

For CD’s approval, cites passage from CD note he wants to quote in a lecture;

pleads for CD’s moral support for FEA’s work in free-thought movement.

Sends $50 [dollars or pounds!?] because he wants CD to become regular contributor to Index.

Thanks CD for five dollars and two-year subscription to Index, and for permission to quote CD’s compliments on Truths for the times.

Asks CD to read and comment, for publication, on his forthcoming essay in Index on the evolution of conscience and morals through action and reaction between man and the moral environment.
