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.
Is sorry to hear that WED has been ill.
Discusses pigeons and his pigeon work.
CD requests further details about a rain of shells on the Isle of Wight reported by a Gardeners’ Chronicle correspondent.
Comments on two pamphlets by John Bachman [probably Continuation of the review of "Nott and Gliddon’s types of mankind" (1855) and An examination of the characteristics of genera and species as applicable to the doctrine of the unity of the human race (1855)].
CD’s pigeon breeding and plant hybridization experiments.
Invites CL to visit.
Naudin’s theory, in J. Decaisne’s review of Flora Indica, of subspecies descended from a single stock only adds to the confusion. John Lindley and M. J. Berkeley cut down species.
Very impressed by Candolle’s book [Géographie botanique raisonnée (1855)]. Wants to recalculate his results.
CD’s pigeon fancy is getting on.
Thanks him for seeds used in immersion experiment.
Sends thanks to M. N. Blytt and says to tell him species names.
Mentions meeting Edward Sabine.
Thanks for seeds. Feels "almost foiled" in his experiments on sea transport – has found few plants that float after more than a week’s immersion.
Sends a list of queries [see 1779] on hollyhocks to put to growers.
Draft of queries on the varieties of hollyhocks. [To be transmitted to William Chater by JSH; probably enclosed with 1778.]
Reports a case of charlock seeds that retained their vitality for at least eight or nine years. He suggests that their power of retaining vitality when buried in damp soil may be an element in preserving the species and therefore seeds may be specially endowed with this capacity, while the power of retaining vitality in dry, artificial conditions may be an indirect accidental quality of little or no use to the species.
Candolle discusses social plants. CD devises criterion for showing sociability not inherent.
Bentham’s buried seed plan rejected.
Is going to London on Thursday [22nd] and would like to call on WBT on Friday.
Reluctantly agrees to write a paper (the citation of award of the Royal Medal to J. O. Westwood [Abstracts and papers of RSL 1855]), but feels unfitted for the job.
Thanks for gift of Souvenirs d’un naturaliste (Quatrefages 1854).
Can AdeQ ask M. J. P. Flourens about experiments which show that hybrid offspring of dogs, wolves and jackals are sterile between themselves in the third generation.
CD cannot obtain a copy of Dureau de la Malle’s work on breeds of horse: can AdeQ assist?
Sends final results of his experiments on the vitality of various kinds of seeds immersed in sea-water. Corrects a false assumption he made in an earlier letter [1684] that plants with ripe seeds would float for some weeks. Now finds that they sink within a month. Since all the seeds he tried sank in sea-water, his experiments are of little or no use "in regard to the distribution of plants by drifting of their seeds across the sea".
Asks TCE’s advice on preparation of birds’ skeletons.
His pigeon collection is growing; now has pairs of ten varieties.
CD not sure that he can come to London.
