CD is asked to increase his shares in the Artizans, Labourers, & General Dwellings Co. Ltd., which has trebled its capital in the last year and is paying a 6% dividend.

Thanks CD for comments on Die Kalkschwämme.

Plans trip to Greece, Asia Minor, and Egypt.

Discusses work of a Polish translator, Ludwik Masłowski.

Thanks CD for Expression.

Suggests saving some anthropoid Quadrumana from extinction by taming and studying them in their own environments to learn about their development.

Asks for references to works on CD’s views for a paper he is preparing.

Sends "squib" he has written exposing the folly of some of Louis Agassiz’s ideas. AG cannot "fire off [his] cracker" in U. S. so sends it to amuse CD. If it is sent to Nature, CD must not give AG’s name. [See "Survival of the fittest", Nature 7 (1873): 404].

Sends a paper on behaviour he has observed in ants.

Additional errata in Descent.

Winter in Duluth.

HAH is leaning toward spiritualism.

Limit of natural and sexual selection.

Has been around the world three times.

Praises TWH’s Army life in a black regiment [1870]. CD always thought well of Negroes, and is delighted to have his impressions confirmed.

CD answers a question about the attitude of foreign naturalists towards Darwinism by distinguishing between the belief in evolution and belief in natural selection. Gives the views of [Louis] Agassiz, [R. A.] Kölliker, [C. W.] Nägeli, [Ernst] Häckel, [C. F. W.] Claus, [F. J.] Cohn, Alphonse de Candolle, [J. L.] Claparède, Asa Gray, Gaston de Saporta, [E. D.] Cope, and [Carl] Gegenbaur.

Hopes JC-B thinks that CD has properly acknowledged his debt in Expression.

Sends his book [Die Befruchtung der Blumen (1873)]. Hopes CD will publish an opinion of it.
