The Binder "by some wonderful Blunder" has bound the enclosed in all of CD’s copies [of Living Cirripedia, vol. 1]. He requests that it be pulled out. It may belong to W. A. Leighton’s volume [Lichens (1851)].

Is glad WED has made a good beginning [at Rugby?].

Questions on variation in nature: taxa varying in one region but not another. Variation between vs within species. Rarity of variation in important organs within a species. G. R. Waterhouse’s views on variation in highly developed organs, which CD relates to variation in rudimentary organs.

Asks for cases of obligate self-fertilising plants.

[CD annotation proposes using the Steudel Nomenclator botanicus (1821–4) to determine if variable species occur in genera with many species.]

Thanks for his letter; hopes he is managing all right [at Rugby?].

Informs JW of his intention to sell his N. W. Railway shares.

Recommends GJ for Government pension.
