Thanks CD for his present of a dram bottle [actually a silver-cased compass]. JG will be reminded daily of their friendship when he is in the wilds [of Australia].

Thanks for ham and corrections in spelling. Gives account of his social activities in past week.

His books grow in size. Hopes to bring out work on volcanic islands and coral formations in the autumn or winter. The Journal of researches will not be published until autumn [actually not until 1839]. Whewell and Lyell flatter him about it. Has given up all society.

Treasures recollections of old friends but seldom sees any. Has turned "a complete scribbler".

His scientific activities.

No wife in sight so far.

Returns his paper for publication ["Volcanic phenomena in South America" (1840), Collected papers 1: 53–86].

Recounts dinner at Erasmus’ house with Harriet Martineau and others, and a visit to Cambridge to stay with Henslow and meet old friends again.

Referee report on CD’s "Volcanic phenomena in South America" [Collected papers 1: 53–86]. Deductions incontrovertible, but theoretical remarks not clearly stated.

Would like to attend a lecture by JFR on "geography of plants with relation to the Himalayas".

"A grand battle" at the Geological Society between Sedgwick and G. B. Greenough.

Asks for permission to have a copy of the published Admiralty chart of the Island of Ascension. The engraved chart will add value to the geological observations to be published in the natural history of the voyage of H.M.S. Beagle.

Has been commanded to supply CD with a copy of the plan of Ascension Island to be engraved for the natural history of the Beagle’s voyage. Suggests that a lithographer be sent to the [Hydrographic] office to take a transfer proof.

Determined to make GRW a geologist. Sends copy of C. Lyell [?Elements of geology (1838)].

Responds to report of the referee [on his paper "The formation of mould"]. Strikes out a paragraph and wants to add a note. Asks WL’s advice about a sentence.

Reports on the effects of inbreeding in dogs and the results of crossing Canada and common geese.

Has not been well.

Plans a geological trip to Glen Roy in Scotland.

Thanks WDF for remembering the crossing of animals, CD’s "prime hobby". "I really think some day I shall be able to do something on that most intricate subject species and varieties."

Thanks CD for suggestions for improving his descriptions of species by indicating localities. With few exceptions the Chalcidites of South America and Australia are remarkably like European species.

Sends to CD, as Secretary of the Geological Society, his work on fossil shells ["Mémoire sur les coquilles fossiles", Actes de la Société Linnéenne de Bordeaux 10 (1838): 92–152].

Express their concern that the offer for sale to the British Museum, by G. A. Mantell and Thomas Hawkins, of two valuable collections, has been declined.

Would like to arrange a meeting about CD’s collection of shells [from the Beagle voyage].

His [first] railway journey was disappointing.

Comments on receiving copy of Lyell’s Elements [of geology]. Much is new to CD, and he is copying out notes and references.

Criticises geological work of John Phillips.

Describes expedition to Glen Roy, about which he is writing a paper ["Parallel roads of Glen Roy" (1839), Collected papers 1: 87–137].

Enjoys the Athenaeum Club.

Criticises entomological work of F. W. Hope.

Asks Lyell to obtain for him a copy of barometric readings made at Leith.

Asks him to ascertain altitude of several Scottish lochs.

Comments on FitzRoy’s character.
