From J. D. Hooker [21 December 1862]
Summary
"Throttled off" Welwitschia paper at Linnean Society [Trans. Linn. Soc. Lond. 24 (1863): 1–48].
Has read Tocqueville’s Democracy in America [1835–40] – disagrees with it. Tocqueville says democracy in America is a success. Democracy has persisted because there has been no cause for its overthrow (i.e., no struggle for existence, too much mobility).
Sends J. W. Dawson’s unsatisfactory letter.

From J. D. Hooker [25 March 1846]
Summary
JDH recognises the existence of "altered states" of continental species in island floras. The botanists’ difficulty in determining a new species is no grounds for dismissing the important question of altered forms.
Will look for Ascension plants for Ehrenberg.
French Galapagos collections confirm JDH’s view that plants arrived from north.
Cannot agree with Forbes on North Atlantic flora.
Botanical definition of "highness" and "lowness" usually means complexity and simplicity.
Some plants, such as aquatic ones, are cleistogamous. Cannot see why they should not be.

From Fritz Müller 1 December 1866
Summary
Gives observations on orchid ovules ripening long after blooming.
Infertility with own pollen sometimes does and sometimes does not indicate dimorphism; gives observations on Ximenia, Eschscholtzia and Oncidium flexuosum.
Describes some striking seeds eaten by birds,
and some new dimorphic species.
Variation in Thillia.
Confirms CD’s suspicion that the lancet-fish [Amphioxus] lives in competition with invertebrates: it shares its habitat with a similar-looking Ophelia, which is quite unlike other annelids, just as the lancet-fish is unlike other fishes.
