Curative power of hydropathy.
General hairiness of alpine plants questioned: direct environmental effect.
CD has long felt JDH is too hard on bad observers.
JDH has shaved the hair off the alpine plant.
CD apologises for his criticism.
Apparent but false relations of plant structure to climate: heath-like foliage of all Cape of Good Hope plants.
JDH’s last letter demolishes woolly alpine plant theory.
Correlation of apetalous flowers and cold climate.
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.
Request for Floras of Pacific Islands and Greenland.
Individual variation.

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.
Embryology of plants of low systematic order. Comparative development begins only with first post-cotyledonary leaves.
Curt letter to JDH from George Henslow.
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 to borrow several Floras. Must redo calculations as John Lubbock has shown him an important error.
No summary available.
Important issue at stake with new flora calculations: evidence that species are only strongly marked varieties. Planning large-scale survey.
Tabulation of varieties goes on; very important as it shows the branching of forms. Mentions his principle of divergence.

Some negative results in variety tabulation survey.
