DCP-LETT-6581

From:
Charles Robert Darwin
To:
Carl Friedrich Claus
Date:
28 Jan 1869
Source of text:
Staatsbibliothek zu Berlin – Preußischer Kulturbesitz (Slg. Darmstaedter Lc 1859: Darwin, Charles, Bl. 205–207)
Summary:

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.
