Hybrid varieties of pheasant and common fowl. Reply to CD queries.
Writes of the extension to Down House.
Is glad WED is in the sixth [form]. Discusses WED’s intention to become a barrister.
Recommends he read passages on bees by C. T. E. von Siebold [in On the true parthenogenesis in moths and bees (1857)].
Will be grateful for facts from Mr Linton on numbers of eggs from goldfinch–canary crosses.
Have all varieties been bred from the same set of eggs so that there can be no doubt they are all the same species?
CD finds Alphonse de Candolle very useful, though JDH has low opinion.
CD argues for accidental introductions explaining some odd distributions, e.g., New Zealand vs Australian plants.
CD’s method.
Diverging affinities in isolated genera.
Thanks AG for 2d part of "Statistics [of the flora of the northern U. S.", Am. J. Sci. 2d ser. 22 (1856): 204–32; 2d ser. 23 (1857): 62–84, 369–403].
Is glad AG concludes species of large genera are wide-ranging, but is "riled" that he thinks the line of connection of alpine plants is through Greenland. Mentions comparisons of ranges worth investigating.
Believes trees show a tendency toward separation of the sexes and wonders if U. S. species bear this out. Asks which genera are protean in U. S.
Sexes of algae.
Congratulations [on Mrs H’s delivery].
Balanus balanoides positively identified by CD.
Thanks for a kind note, and asks not to answer until better.
Thanks for information, which is just the amount he wanted.
Will not go to the BAAS meeting in Dublin: the frightful voyage deters him.
Will attend to any subject in Jamaica about which CD wants information.
Crithagra brasiliensis and canary refused to pair.
A collection of Jamaican land Mollusca will be presented to the British Museum.
Hurricanes are a considerable influence on diffusion of birds and insects.
Enumerates fossil mammals known in Secondary strata.
Lack of angiosperm plants in rocks older than Chalk is no reason to anticipate rarity of warm-blooded quadrupeds.
CD will advise W. F. Daniell on collecting.
Asks THH question on flow of glaciers after ice has been fractured and fragmented.
CD had to leave Royal Society lecture [joint paper by THH and J. Tyndall, "On the structure and motions of glaciers", Philos. Trans. R. Soc. Lond. 147 (1857): 327–46] before the end because of headache.
CD will advise Daniell not to apply for Royal Society grant.
CD’s experiment: fish fed seeds, which germinated when voided.
Sends specimens of Tortrix, which illustrate the extraordinary variation of markings in two or three species. In every family of Lepidoptera there seem to be species extremely prone to vary and in some localities they vary more than in others.
Thanks THH for his response on glacial movement. Hopes Tyndall will experiment on broken ice and explain how two pieces of ice can freeze together.
Sorry to hear of THH’s row with Richard Owen.
