About JH's travels and viewing of prospective homes to which to move; saw Collingwood.

Suggests arrangements for submission of papers, reports, models, etc., to the B.A.A.S. meeting.

Recounts experiments with chemicals, spectra, and photographic paper.

Regrets that JH had to write another letter regarding the two papers he forwarded. Missed him when in London. Saw L. J. M. Daguerre's specimen and also those of J. N. Niepce, the latter undoubtedly the originator. Has made an excursion to the volcanic region of the South of France.

Intends erecting his large constant battery in the course of a few days and wonders if JH or Charles Babbage would be interesting in seeing it.

Hopes JH will honor his election by attending his dinner on Saturday.

JDH has already written to his brother William Henslow Hooker & sister Bessy [Elizabeth Hooker] and now writes to his father, William Jackson Hooker. He explains that the expedition will not sail as soon as expected but JDH is unlikely to be allowed leave, by Captain [James Clark] Ross. The result is JDH will not be able to come home to Glasgow in the interim, certainly not until the surgeon, McCormick has returned to the ship. JDH & a Mr Ward are going on an excursion to Cobham. The Botanical commission of the R.S. [Royal Society] did not have the civility to say bon voyage to JDH. Mentions sending seeds to the East India Company. Mentions his father's communications with Talbot, Arnott & Champion & other botanists. Comments that Cape Palmas & Fernando Po are 'glorious stations', he regrets that the expedition will not stop at the Cape de Vers [Cape Verde islands]. Asks if WJH knows of a cruciferous Kerguelens Land plant, which he has heard from Brown appears in Anderson's journal. Asks if his sister Maria would copy out a list of Antarctica & Enderby Land plants for Ross. Asks about the Murrays' being in London. Commiserates with Dr [Harry] Rainey who he considers an excellent lecturer, only equalled at [Glasgow] college by WJH & McKenzie.

JDH explains to his father, William Jackson Hooker, that Captain [James Clark] Ross has been unable to confirm if JDH can take leave, he is reluctant to grant it as the surgeon & captain of the HMS 'Terror' are both away at present. Ross is angry that the ships 'Erebus' & 'Terror' are not yet in a condition to sail. McCormick has discovered that there is little support for the natural history element of the expedition from government or from Sir William Parker [of the Admiralty], which has also upset Ross. McCormick is still committed to pursuing natural history & encourages JDH in the same. JDH has been organising medical supplies & tending to some of the men from the 'Terror' who are generally less healthy. Discusses the expense of equipping the mess for a four year voyage. He enumerates his own expenses since leaving Glasgow, including purchase of instruments from Weiss, & what his pay is compared to his shipmates'. He would like to lend some money to Dayman to help him pay his debts, otherwise the practice is to deduct the amount of any outstanding debt from his pay when the ship is paid off. They will be paid on reaching the Nore. Mrs Richardson has introduced JDH to people in Chatham incl. the Davies. He has not met Mrs Wavell, as Mrs Kay suggested, as she is in Hastings. Thanks Mrs Kendall for her interest, her brother is a great favourite. Dr Smith is ill, when JDH visited him Smith lent him [Charles] Darwin's journal which JDH thinks highly of & would like to buy. JDH has also read up on the voyages of Captain [James] Cook, [George] Anson & [John] Byron. JDH is anxious about a letter of advice he gave to William [his brother William Dawson Hooker].
