CD asks his father to consider the offer of the Beagle voyage once more. He encloses his list of RWD’s objections and Josiah Wedgwood’s responses [see 109]. Asks his father to give him a decided answer: if "no" he will never again mention the subject.

Spent preceding day with Henslow; much to be done. A friend, Alexander Charles Wood, has written to Capt. FitzRoy about CD. Peacock offered appointment as Beagle naturalist first to Leonard Jenyns, who almost accepted, as did Henslow himself. CD will talk to Capt. Francis Beaufort [Hydrographer] and FitzRoy. Thanks all his family.

Wood has heard from FitzRoy, who seemed so much against CD’s going that CD and Henslow gave up. CD is in London; has seen FitzRoy, who is now ready to invite him. CD remains undecided. He likes FitzRoy. Gives details of prospective arrangements. They probably will be gone three years; "round the world" is not certain. Want of room is a serious objection.

Orders clothing, books, and other supplies for the voyage, to be sent to him in London.

Discusses help he is receiving in his preparations for the voyage from William Yarrell and others. He has ordered a case of pistols, a rifle, and a good telescope with compass. It is settled that he will go.

Describes the coronation of William IV.

Pleasant three-day voyage to Plymouth has increased CD’s admiration for FitzRoy. Describes the Beagle as an excellent vessel, but the want of room is very bad. He likes the officers.

Plans to come to Shrewsbury.

Is pleased with cabin assignment on Beagle. Beagle will map the east side of Tierra del Fuego and Patagonia and set longitude of many places.

Reports on errands he has done for RF. Has discussed with Beaufort the question of his having right to dispose of his collection.

CD’s luggage is frightfully bulky, though he has been as economical as possible. Has made financial arrangements for his expenses.

Plans to study mathematics during voyage.

Has just heard Beagle sailing is delayed so he will remain another week in London. Asks whether RF has a good set of mountain barometers, which geologists tell him are important.

Writes with great happiness about the first part of the voyage, after his misery from seasickness passed. He finds himself well prepared, the ship quiet, comfortable, and compact; he has already a "rich harvest" and finds the natural history (especially geology) exceedingly interesting. The tropics are full of great beauty.

Sends a short résumé of his trip on the chance that it will arrive in England earlier than longer letter [158] which he hopes to send by surer means.

He is "incessantly occupied by new and most interesting animals" and thinks he will be able to do some original work in natural history.

Regrets leaving the tropics, despite interest in a land where Europeans have never been. They have experienced political turmoil at Montevideo. Natural history going well.

Brief summary of the voyage so far. His delight in the Brazilian forest; his trip into the interior; the turbulence at Rio; has grown a beard.

Has had to draw bills totalling £217 in seven months.

Is glad the Captain has decided to winter in Tierra del Fuego, because this will facilitate "glorious excursions" into the Andes.

Has obtained fragments of fossil bones and part of a Megatherium head.

Their long delay occurred because the charts were not complete for sending home.

CD is now on shore because of seasickness.

The family may not hear from him for a year.

Recounts his trip [from Valparaiso] to Santiago. His meeting with Claude Gay, Thomas Sutcliffe, and others. Geology of tour uninteresting.

His trip across the Andes and back was his most successful excursion: can clearly demonstate that the western part of the double line of mountains is much older, with fossil shells at 12000ft; the eastern line may be as modern as the Patagonian plains. If proved, this is an important fact in the theory of the formation of the world. Has found petrified trees.

Memorandum of geological instructions to guide ABU during a voyage of [Constitucion] to survey the coast of Peru.

Living quietly on the ship and eating good food has been good for him. He longs for home. Peru is in a miserable state.

CD’s impressions of Sydney and of FitzRoy’s character and temperament.
