Has read in the newspapers about the album of photographs of German scientists sent in tribute to CD. His name and photograph are missing only because he was not asked to participate. CC assures CD he is one of his ardent supporters.
Sends a paper on reproductive modes of Leptodera ["Organisation und Fortpflanzen von Leptodera", Schr. Ges. Beförd. Naturw. Marburg (1869)].
Criticises Ernst Haeckel’s work as too unripe and enthusiastic.
Asks CD for some specimens of cirripedes in pupal stage for a work in progress.
Pleased by CD’s good opinion and offer to provide material. Discusses work he would do on cirripedes.
Moritz Wagner’s views on migration of species;
his doubts about Fritz Müller’s views on developmental stages of Crustacea.
The cirripede material mentioned in CD’s letter of 10 Feb has not arrived. [Asks CD to inquire of Williams and Norgate, who forwarded it.]
Thanks CC for dedication [of his Grundlage des Crustaceen-Systems (1876)]. Congratulates CC on completion of work.
Thanks for copy of Claus’s book, Untersuchungen zur Erforschung der genealogischen Grundlage des Crustaceen-Systems: ein Beitrag zur Descendenzlehre (Studies on the investigation of the genealogical foundation of the Crustacea: a contribution to the theory of descent; Claus 1876).
Warm thanks for CC’s letter. CD needed no word from CC to be convinced of his high opinion.
Thanks CC for two memoirs [see 6575. The other was possibly "Die Cypris-ähnliche Larve der Cirripedien", Schr. Ges. Beförd Naturw. Marburg (1869)].
Haeckel is too enthusiastic and too bold in drawing conclusions.
CD sees no reason to add to what he says on isolation, in new edition of Origin.
Lists specimens he has available for CC’s intended study of metamorphoses of Lepas.
Williams and Norgate inform CD that they dispatched the small parcel to Leipzig on 23 February. CD fears it may not be worth the trouble to CC.
