"Mr Darwin presents his compliments to the Master & Fellows of Caius Coll. and is extremely sorry he is prevented by a previous engagement the honor of dining with them on Thursday."

Informs WDF of his activities since the Beagle landed.

Has written to Royal College of Surgeons, exactly as RO recommended, concerning disposition of his South American fossil bones. He fixed on the British Museum, rather than Paris, to receive plaster casts, because he was on board a King’s ship. Suggests RO propose another set for Paris, where they would be more useful than at BM. Has scarcely begun unpacking his cases.

Asks CD’s help in finding a tutor for his son Charles.

Has returned CD’s Beagle journal MS. Thinks it would be an interesting account even if they did not know CD, and that it will be successful if published; the less it is mixed up with FitzRoy’s journal, the better.

Has been presenting wedding gifts to her nieces and nephews during CD’s absence, without asking whether they are ready for them, so she sends him £40.

Caroline says CD has taken a lecture room for his work at Cambridge.

The Royal College of Surgeons’ Board of Curators approve the terms and conditions under which CD has offered his S. American fossil bones to the College, and have sent their recommendation to the Council.

Comments on [MS of] CD’s paper ["Elevation on the coast of Chili" (4 Jan 1837), Collected papers 1: 41–3].

Invites CD to dinner. "Don’t accept any official scientific place, if you can avoid it".

RF has consulted W. J. Broderip, who recommended a joint three-volume publication of Captain King’s journal, FitzRoy’s, and CD’s, with profits divided by three. What does CD think of such a plan? RF promised Colburn an answer in January.

They have been reading about the wreck of the Challenger; much impressed by Capt. FitzRoy’s bravery.

The W. D. Foxes have a daughter. Family news.

All prefer Hobart Town and its society to Sydney. CD’s view on emigration to colonies. All on board are homesick.

News of friends and family.

Keeling Islands, his first coral lagoons; he has been occupied with subject of coral formation for six months.

Very busy at sea rewriting old geological notes. Has difficulties with writing.

FitzRoy has proposed joint account of the journey, combining CD’s journal with his own.

Looks forward with anxiety to Henslow’s reaction to the geological notes.

Will call on Sir J. Herschel, then take short trip in the African desert.

Horrified at the publication of "the little book of extracts" from his letters to Henslow ["Letters to Professor Henslow" (1835), Collected papers 1: 3–16].

A defence of the work of missionaries in the Pacific islands and Australia. [The letter was apparently written by RF with supporting evidence quoted from CD’s journal. The letter is signed by RF alone. A summary conclusion, as printed, is signed by both:] "On the whole, balancing all that we have heard, and all that we ourselves have seen concerning the missionaries in the Pacific, we are very much satisfied that they thoroughly deserve the warmest support, not only of individuals, but of the British Government."

In five days of geologising on St Helena, he found that the shells on high land had been mistakenly identified as seashells. They are land shells, but of species no longer living.

Can think of nothing but the return to England and his family.

Last four days have been spent calling on naturalists. Geologists have been kind, but zoologists seem to think a number of undescribed creatures a nuisance.

Will send his belongings to Cambridge, but eventually his quarters must be London.

FitzRoy is to be married.

His fossil bones are unpacked and some are great treasures. He has some geology to do: R. I. Murchison has lent him a map and asked him to look at a part of the country he has been describing.

Their only protection against having Harriet Martineau as sister-in-law is that she works Erasmus too hard.

Dinner at the Hensleigh Wedgwoods’. They have agreed to go over his journal. Henry Holland thinks it not worth publishing alone because it goes over FitzRoy’s ground.

His impressions of Harriet Martineau: "She is overwhelmed with her own projects, her own thoughts and own abilities."

"Read a letter [to AC] of the 19th Instant from Mr Charles Darwin of Christs College, Cambridge stating that understanding from the Conservators that a Series of fossil Bones collected during the voyage of H: M: Surveying Vessel Beagle possesses a peculiar Interest as connected with Specimens already in the Museum of this College that it had always been his intention to present such Bones to some public collection on the condition that Casts thereof should be given to the leading Public Bodies for the sake of making them more generally useful, specifying the British Museum the Geological Society and the Universities of Cambridge and Oxford, and one set for himself: and that under such Conditions he should be most happy to present the entire series to the Museum of this College."
