Thanks AD for his article in Das Ausland ["Englische Kritiker und Anti-Kritiker über den Darwinismus", 49 (1871): 1153–7].

Mivart’s book [Genesis of species], which misinterprets CD’s views, has produced a great effect in England.

He has answered the point about incipient structures being useless in new [6th] edition of Origin.

His Descent has had immense circulation, but has met with approval of hardly any naturalists. He supposes it was a mistake to publish it, but it will pave way for a better work.

AD is sorry CD thinks publication of Descent a mistake. The excitement shows it was necessary for someone to speak plainly.

His great difficulties (Italian indolence, dishonesty, hatred) in establishing zoological station. Can at last start construction.

Has reported on the Naples Zoological Station to BAAS meeting at Brighton. Hopes to open it in January. Is at work building up the library by contributions from publishers and naturalists.

Deplores Wallace’s "drifting away" and his association with such men as H. C. Bastian.

Disbelieves in ascidians as our ancestors. Has a substitute he is sure will please CD.

Rejoices at success [of Naples Zoological Station]. Will send complete set of his books to the library.

If AD is interested, he will send a copy of Expression when it comes out.

Invites AD to visit Down.

Will call on CD next year, when he will have worked out the embryology of Amphioxus; he believes it is not primitive but a degenerate form of fish. He believes the true ancestors of vertebrates are annelids.

Is amazed at Expression. Like CD’s former works, it contains the material and principles of a new science.

The Zoological Station is making good progress – now has a fine building. Hopes for a stable income from contributions of various governments.
