JDH’s last letter demolishes woolly alpine plant theory.
Correlation of apetalous flowers and cold climate.
Thanks for new part of "Statistics".
Interested in disjoined species; do they tend to belong to large or small genera, and are they generally members of small families?
Is glad AG will tackle introduced plants; has noticed that the proportion of a particular family to the whole flora tends to be similar in introduced and indigenous plants.
Accepts a dozen eggs of rumpless Polands. Having so many enables him to see whether the breed "comes true".
Asks what colour turbits have dark tails – "it is just the class of facts which interest me".
Do fowls when crossed throw odd and unexpected colours like pigeons?
Discusses family health and affairs.
Asks JDH’s opinion, and botanical evidence, on important law: parts that are highly developed in comparison to other allied species are very variable.
Interest in hairiness of alpine plants revived by reading A. Moquin-Tandon [Éléments de tératologie végétale (1841)]; correlation with dryness. CD seeks interpretation independent of direct environmental effect.
Lists pigeons and poultry he is forwarding to WBT.
Wants details of WBT’s Poultry book [1856–7]
and is anxious to purchase his long-winged runt.
Thanks him for help and information on fowl crosses.
Agrees with Thomas Henry Huxley that Albany Hancock has a good claim on a Royal Society medal. Thinks that geology has not been sufficiently honoured by the Royal Society, and suggests Joseph Prestwich. Expresses his strong opinion that Charles Lyell would be a worthy recipient of the Copley Medal.
Thanks him for information concerning Crustacea.
Comments on natural history study in the U. S.
Mentions work done by Huxley on Crustacea ["Description of a new crustacean", J. Geol. Soc. Lond. 13 (1857): 363–9];
John Lubbock on larvae of Diptera.
Is trying to find a tutor for WED.
Writes of WED’s recent excursion to Manchester and his future educational plans.
Qualifications of John Lindley, Huxley, Albany Hancock, Joseph Prestwich, J. C. Ross, and Francis Beaufort for Royal Medal.
Supports nomination of John Lindley for award of Royal Medal of the Royal Society.
"Law" [see 2092] correlating variability and abnormal development not confirmed by JDH for plants.
CD studies struggle for existence in his weed garden.
Scotch fir observed at Moor Park.
Royal Society medals.
Correlation of variability and abnormal development is G. R. Waterhouse’s law. Relation of this law to polymorphism.
Colouring and marks of ancestral horse deduced from facts observed in pigeons.
Comments on TCE’s work [Catalogue of the species of birds in his collection (1856)].
Mentions African dog’s skin.
Asks about colours of horses
and about variation in tracheae of male birds.
Requests information from readers on breeding of dun or mouse-coloured ponies with a dark stripe down their backs. Must one or both parents be dun?
Is glad WBT is investigating "the tail question"; hopes he will work out "down & colour point". Is much interested in runts, which seem to vary more than other breeds.
Thanks for AG’s remarks on disjoined species. CD’s notions are based on belief that disjoined species have suffered much extinction, which is the common cause of small genera and disjoined ranges.
Discusses out-crossing in plants.
Has failed to meet with a detailed account of regular and normal impregnation in the bud. Podostemon, Subularia, and underwater Leguminosae are the strongest cases against him.
CD anxious to examine rumpless chick 24 hours before hatching.
Needs only one nearly-hatched chick.
Has all published numbers of Poultry book [1856–7].
