Details about FitzRoy and proposed voyage of Beagle. CD invited to go on the voyage as naturalist.

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.

Reports on his geological work in N. Wales since he and CD parted. Answers CD’s queries.

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.

Suggestions and information helpful to CD in preparation for Beagle voyage. David Brewster’s meteorological papers. Suggests an oyster-trawl for collecting marine animals. Recommends CD see R. E. Grant. For meteorological observations suggests F. W. Beechey’s Voyage to the Pacific [1831] and an interview with J. F. Daniell of King’s College.

Congratulates CD on Beagle appointment as an "opportunity … of studying all the natural sciences at once, after your own taste".

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.

Reports on a setter puppy born of apparently pure pointer parents. Any cross must have been far back.

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.
