Thanks JH for interest taken in periodic phenomena. Discusses train information and preferred hotel accommodations for JH's visit.

Proposes meeting times in town. Suggests that JF observe the upcoming total eclipse astronomically. Agrees with JF's seemingly 'cold &c' circular on scientific partnerships, while regretting that it needed to be written.

About the length of a Board of Visitors' meeting, and about arrangements afterward.

Sets up approximate meeting time, depending on his family's timely departure to Antwerp, with JF at the R.S.L. apartments.

Some information about Charles Piazzi Smyth. JH needs information about some of RH's photographic paper, which JH has tried but without success.

Thanks WS for C. P. Smyth drawings of Cape monument and Gamma Virginis observations. Notes J. H. Mädler's work on double stars and the doubt that they obey the inverse square law. Discusses use of photography in astronomy.

Will JH be prepared to present report on 'Nomenclature of Stars' at Manchester meeting in June?

Would like to see him for a few minutes to discuss a paper he is preparing for the R.S.L. on actinometer observations.

No meeting of the R.S.L. on the 19th but could arrange to see him before dinner. Hopes to spend the summer amongst the glaciers.

JDH writes this letter to his father, William Jackson Hooker, to accompany some articles ordered by JDH, Mr Gull & Lieutenant Smith. Captain Holt of the brig 'Champion' was to get the items at Valparaiso & deliver them to JDH et al back at the Falkland Islands. In the event that is not possible JDH has asked that they be forwarded to WJH with the bill.

JDH writes to his sister, Maria. He wrote to others by the HMS 'Arrow' on 3 May 1842. HMS 'Champion' has stopped at the Falkland Islands & JDH met with Captain Holt, who is his 'scotch cousin' through familial links with Shelly of Barmouth & Tom Brightman's sister. The latest newspapers JDH has seen are from March with news of the Prince's christening, Queen's speech, bankruptcy of an unrelated Hooker, & death of James McCall of Daldowie. Mentions the failure of 'the African Expedition' & compares with their own Antarctic expedition. JDH has been on a trip to Port William with the Governor [Richard Clement Moody] on the HMS 'Alarm'. Describes the country around Port William. Compares a Port William grass known as 'tussac' with the 'true Tussac grass', which JDH thinks is Dactylis glomerata, & describes the habit of the latter in the Falklands. On the trip JDH collected seaweeds, lichens, new plants & few shells incl. rare Voluta magellanica. JDH has found more plants than expected in the Falklands, especially given the late season. The ship ['Erebus'] is being repaired. As it is now winter JDH's collecting will be confined to lower order plants. The days are short, the nights long & the weather stormy making life in a tent uncomfortable. He describes how they line the tent floor with gravel & sleep in 'blanket bags'. JDH likes Governor Moody, whose father was Lieutenant Governor in Guernsey. Mentions the return of Wilmot & Lefroy, Baron Humboldt & the King of Prussia visiting London. Davis is making a sketch of the ships in the ice for William Jackson Hooker, JDH will send oak to frame it. JDH would like info on the Hooker's new home at Kew. Notes that the Antarctica expedition has not been in the press. On the Queen's birthday they had a smart dinner. Wonders if Balfour or Arnott is the new Glasgow University Chair of Botany. JDH intends send Dawson a Matchero from Valparaiso. Asks Maria to send him new spectacles, an eye glass & some lichens: Cud-bear & Archill.
