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].
