Thanks for new [6th] edition of Origin, which he read with great interest. Would welcome an edition with references to works cited.

Saw editor of the Pall Mall Gazette about review of Origin and Genesis of species.

Enclosed account has had charged against it difference in costs between type composition in the U. S. and securing stereotype plates from Murray. CD should insist on securing plates from the London publisher of all future books, otherwise Appleton unable to pay 10% of gross price.

Wants AR to make any observations she can on the occurrence of little ledges on the side of steep, turf-covered slopes. Feels they may result from the washing down of worm-castings.

Reports the case of a cockerel raised in isolation from other cocks which repeatedly attempted, but failed, to crow properly.

Also discusses behaviour in horses; one male will "look after" 20–25 females.

Glad AW’s eyesight is better.

Has received AW’s essay [Einfluss der Isolierung (1872)].

Glad he is turning attention to sexual selection. Hardly any naturalists agree with CD on subject.

Disagrees with the "Darwinian theory"; does not see evidence enough to support it. Will send CD any notes he makes for or against.

Received copy of Origin 6th ed. Has had trouble with worm measurements at Winchester.
