Requests Linum, for dimorphism study.

Reviewer of Orchids [Nat. Hist. Rev. n.s. 2 (1862): 371–6]is correct about the organisation of the book; he wonders who the reviewer is.

Extreme interest in MS of HF’s paper on the American fossil elephant [Nat. Hist. Rev. n.s. 3 (1863): 43–114].

Pleased HF does not believe in immutable species. Significance of proboscidean group verging towards extinction. Comments on natural selection preserving type despite variability. Natural selection solves problem of how every part of each creature has become adapted.

Thanks for opinion on Drosera. After working for a time on a subject he is absolutely incapable of judging its value.

Has found a case in Lythrum of a necessary triple alliance between three hermaphrodites; the strangest case of propagation recorded among plants or animals.

Asks for L. thymifolia to see how a trimorphic form passes or graduates into dimorphic.

Questions JDH on Linum perenne.

Has found 33 hybrids in one field between Verbascum thapsus and V. lychnitis. The perfect series of varieties would have justified running the species together, but every one of the intermediate forms is sterile.

Thanks for Aldrovanda reference and Cassia.

Has wasted labour on Melastomataceae without getting a glimpse of the meaning of the parts.

Wants seeds, from their native land, of Heterocentron or Monochaetum.

Is beginning to change his view about rarity of natural hybrids.

Would like JL to call.

Asks WED to make some observations on differences in pods of Lythrum.

Masdevallia turns out to be nothing wonderful, "I was merely stupid about it."

Asks for plants for experiments.

Hedysarum and Oxalis sensitiva seeds.

Asks whether Oliver knows of experiments on absorption of poisons by roots.

CD finds he cannot publish this year on Lythrum salicaria; he must make 126 additional crosses!

Asks for odd variations of common potato; he wants to grow a few plants of every variety.

Variation is crawling.

Has had some bad attacks lately.

Thanks WED for observations on Lythrum.

Discusses family affairs.
