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.
Discusses difficulties involved in deciding which genera are protean in the light of some comments by H. C. Watson.
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?
Sends a reference to Subularia which bears on a query CD made some time ago [see 2002]. Subularia was seen to flower in the air in a remarkably dry season.
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].
Seedling leaves of gorse look like clover leaves. This is like young lions being striped. Thus, laws of animal embryology apply to plants.
Ill.
Comments on TCE’s study of birds’ bones.
His work on variation progresses.
Asks about horses with bars like zebra or ass.
Embryology of plants of low systematic order. Comparative development begins only with first post-cotyledonary leaves.
Curt letter to JDH from George Henslow.
Has acquired some runts. Thanks WBT for information. Lists pigeons he is sending.
Memorandum about £250 investment in Patent Siliceous Stone Company, owned by David Thomas Ansted and Frederick Ransome.
George Henslow’s curtness to JDH: "an attack of religion".
Embryonic leaves. Adaptive functions and taxonomic significance of cotyledons.
Asa Gray. Separation of sexes in U. S. trees.
Does JDH’s Wahlenbergia confirm CD’s law? Variations of one species assume the character of a distinct but allied species or genus.
Seed-salting: old ones float and germinate.
Owen’s "grand paper" [? J. Proc. Linn. Soc. Lond. (Zool.) 2 (1858): 1–37].
Asks THH’s opinion on embryological views of G. A. Brullé [Ann. & Mag. Nat. Hist. 13 (1844): 484–6] and F. M. Barnéoud [Ann. des Sci. Nat. ser. 3, Bot. 6 (1846): 268–96] and on Milne-Edwards’ classification.
Has been reading John Goodsir ["On the morphological constitution of the skeleton of the vertebrate head", Edinburgh New Philos. J. 2d ser. 5 (1857): 123–78].
Has embryology of bats ever been worked out?
THH comments on G. A. Brullé’s paper ["Researches upon the transformations of the appendages of the Articulata", Ann. & Mag. Nat. Hist. 13 (1844): 484–6].
