The Charles Darwin Collection
The Darwin Correspondence Project is publishing letters written by and to the naturalist Charles Darwin (1809–1882). Complete transcripts of letters are being made available through the Project’s website (www.darwinproject.ac.uk) after publication in the ongoing print edition of The Correspondence of Charles Darwin (Cambridge University Press 1985–). Metadata and summaries of all known letters (c. 15,000) appear in Ɛpsilon, and the full texts of available letters can also be searched, with links to the full texts.
Thanks for Edward Forbes’s letter. Botanical evidence conflicts with parts of his theory but supports others. Is becoming more of a migrationist.
Bentham agrees with JDH on polymorphism.
Describes Infusoria in Rio Gallegos samples.
"Fluthgebiete" means estuary deposit.
Discusses dust samples from Malta. Asks for further samples.
Agrees with JDH about Forbes’s views.
Discusses A. Saint-Hilaire’s lectures and asks on what grounds botanists judge the relative "highness" of plants.
C. G. Ehrenberg wants specimen grasses from Ascension Island.
Sends copy [of "Fine dust in the Atlantic Ocean", Collected papers 1: 199–202]. Attempting to obtain further samples for CGE.
JDH recognises the existence of "altered states" of continental species in island floras. The botanists’ difficulty in determining a new species is no grounds for dismissing the important question of altered forms.
Will look for Ascension plants for Ehrenberg.
French Galapagos collections confirm JDH’s view that plants arrived from north.
Cannot agree with Forbes on North Atlantic flora.
Botanical definition of "highness" and "lowness" usually means complexity and simplicity.
Some plants, such as aquatic ones, are cleistogamous. Cannot see why they should not be.
If JDH can send grasses CD will write to Ehrenberg enclosing them.
Sends specimens of grasses from Ascension Island for CD to forward to Christian Gottfried Ehrenberg.
Includes list of indigenous flowering plants of Ascension Island.
Discusses publication of his book [South America].
Sends a list of mammalian remains found in the Buenos Aires district and purchased by the British Museum.
Thanks for the gift of Frémont 1845. Has had a visit from R. J. Mackintosh and his wife Mary, Appleton’s sister.
Thanks for his note; as soon as CD knows how many Cordillera Tertiary fossil shells require illustration he will make arrangements for GBS jr to begin.
