Lectured on Darwinism in Cincinnati, Minneapolis, Buffalo, and to 3500 people in New York City.

Despite close friendship with Cope and Hyatt and many explanations by the latter, he cannot understand their views.

Thanks CD for appreciation of his papers.

Sends proofs [of "The shell mounds of Omori, Japan", Tokyo Univ. Mem. 1 (1879)], which may interest CD for the changes between ancient and modern forms.

Offended by F. V. Dickins’ review [Nature 21 (1880): 350] of his Omori mound paper. Asks CD to have it reviewed elsewhere and encloses a letter to Nature he wants CD to forward. [See 12571.]
