Believes the flexure in GM’s dead animals must result from the greater strength of the muscles on the left side. Thinks his son George once tested the strength of each leg of a group of boys, and CD could get his notes if wanted.

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 GM for his excellent criticisms. His observations on the classification of minerals force him to "own that classification may be closely like that due to descent yet have no relation to it".
Asks whether GM has observed any cases of "bud-variations".
Thanks GM for his fair review [of Origin, Zoologist 19 (1861): 7577–611].
Feels it is a pity to mingle science and religion;
explains why he did not deal with the case of man.
Has read GM’s review and thanks him for its fair and liberal spirit. Discusses briefly several specific difficulties raised by it.
Would welcome any facts on correlation, or GM’s criticisms. Explains how natural selection could produce apparent correlation of characters, but feels GM’s Pelargonium example must arise from the leaves and petals being similarly affected at an early stage by an unknown cause.
Thinks GM’s Pelargonium is a case of true correlated characters. Feels secondary sexual characters are only accidental correlations; does not see the same necessity for close simultaneous development of certain characters as GM does.
Will forward a copy of his Orchids.
Thanks GM for a curious lily.
Recommends some papers on coal.
Gives his opinion on the importance of forming theories if one is to be a good and original observer.
Believes GM’s human bones from Gibraltar must be of very doubtful age. Lyell agrees, but feels any skull found should be forwarded to George Busk or Hugh Falconer.
Suggests GM look carefully for shells in the drift.
Believes GM’s reported monstrosity is not rare. Does not believe it resulted from the effect of the imagination of the mother on her offspring.
Thanks GM for a specimen; it is a sport with which he is already familiar.
Thanks GM for offer of observations. Would be interested to know when the horns of merino rams first appear,
and has long wished for living specimens of Drosophyllum.
Describes Drosophyllum and its habitat.
Thanks GM for specimens of Drosophyllum; by a strange coincidence CD has also received plants from a correspondent in Oporto [W. C. Tait].
Thanks GM for specimens of Drosophyllum.
