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.
