Summary

Birthday greetings.

Summary

Thanks CD for his cheque for £100. Has told Secretary of BAAS Committee [for the Station], so that he may report it. [See O. J. R. Howarth, The British Association (1931), pp. 196–7.]

Summary

Regrets he is too busy to accept CD’s invitation to visit Down, but could only thank him again for saving the Zoological Station from shipwreck.

Summary

Thanks CD for his support and for his cautionary advice.

Will send his work on embryology of arthropods as soon as it is finished [Bau und Entwicklung der Arthropoden (1870)].

Summary

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.

Summary

Thanks CD for Variation.

From his work on insect embryology he sees a great parallelism between insect and vertebrate embryology.

The zoological station is slowly advancing.

Summary

Thanks CD for his offer. Suggests it be used to start a fund to pay travel expenses of English naturalists who want to come to the Station.

Summary

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.

Summary

AD is aware of revolutionary character of his pamphlet [Ursprung der Wirbelthiere]. Authorities will not agree with him. Carl Gegenbaur and Ernst Haeckel are opposed. Younger biologists are disposed to accept his views. All he can expect is to put a stop to "the Amphioxus–Ascidian affair, and to open a road for speculation and for investigation on the side of the Annelid-homology".

Summary

The Naples Zoological Station and its library are growing fast. His life is a constant battle with the municipality, but has managed to make a little progress on vertebrate ancestry and morphology. His views get further away from what is generally accepted.

Summary

Belated birthday greetings

and reminiscences of CD’s help to the Station, which continues to prosper. A recent innovation is the establishment of the Zoologische Jahresbericht edited by J. V. Carus.

Summary

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.

Summary

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.

Summary

Sends birthday greetings

and the good news of a subvention for the Zoological Station received from the German government. There are now 20 naturalists working at the Station.

Summary

Thanks to CD’s help Zoological Station has passed a crisis and is now flourishing.

Is writing pamphlet on "the origin of vertebrates and the principle of succession of functions" [see 9991 and 10003]. It is likely CD will not be pleased with it, but he thinks he must now, after seven years, bring it out. Seeks to open the way for a new series of theoretical questions.

Summary

Birthday congratulations from the Naples Zoological Station. A new physiological department will be constructed. Describes work in progress at the Station.

Sends his paper on teleosteans.

Heard R. Owen read a paper at York [meeting of BAAS]. Owen had views similar to AD’s, but seemed not to be aware of work of others.

Summary

Reports on the international support he has obtained for the zoological station [see 7038]. Asks CD whether he will serve on a board of naturalists who would receive an annual report on the station.

Huxley is now convinced by AD’s views on homologies of the nervous system of arthropods, annelids, and vertebrates. Kovalevsky takes the same line but does not go far enough.

Summary

His gratitude for CD’s gift. An account of his difficulties with the Zoological Station and his health.

F. M. Balfour has told him that CD would like to see the question of complemental males in cirripedes studied again. AD would like to enter the field and to study the whole morphological development of cirripedes.

Describes the interest in embryological work in Russia and Germany.

Summary

Pleased by CD’s letter; his object was to apply CD’s principles to the reform of zoology. When this is done, it is wonderful to see how improved one’s understanding of the Crustacea (Arthropoda) becomes. Cites examples.
