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.
"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.
Seedling leaves of gorse look like clover leaves. This is like young lions being striped. Thus, laws of animal embryology apply to plants.
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].
Thanks JL for saving him from "a disgraceful blunder". Following their conversation he has divided the New Zealand flora as JL suggested and finds genera with four or more species are more variable than those with three or less. It will take several weeks to go back over all his material.
Asks to borrow several Floras. Must redo calculations as John Lubbock has shown him an important error.
Important issue at stake with new flora calculations: evidence that species are only strongly marked varieties. Planning large-scale survey.
Delighted that JSH is coming to Down. Sends correct train time.
Tabulation of varieties goes on; very important as it shows the branching of forms. Mentions his principle of divergence.
Reports progress of work on the new rooms [at Down].
Some negative results in variety tabulation survey.
Galls on wild carrot.
Discusses WED’s future education, the work on the extension, and other domestic affairs.
C. F. Ledebour [Flora rossica (1842–53)] particularly useful for variety tabulation. Results generally favourable.
Additions to Down House.
Last two chapters of MS took six months to write.
Huxley and William Sharpey praise JL’s paper [? on Daphnia, Philos. Trans. R. Soc. Lond. 147 (1857): 79–100] at Philosophical Club.
JSH’s Myosotis is beginning to sport. Asks whether some features are not odd.
Sends details on Myosotis sports. Feels sure he could make any flower in some degree monstrous in four or five generations.
