JDH knows that the Rajah spread news that he & [Archibald] Campbell [AC] were dead & wants to know if the misinformation reached England. He believes they will soon be released. He will then go to Nepal, where the Rajah is more honourable & has given Lord Dalhousie his consent for JDH to explore the region. He shall go once [Thomas] Thomson joins him & he has sent his collections to Darjeeling. JDH describes their imprisonment & the Bhotia authorities; the Lepcha people sympathise with them. The Lamas are now supporting them too. The Rajah is in a difficult situation; the Superintendent of Darjeeling will continue his course of action. JDH describes AC’s character & health. Their only contact with the Durbar [Court] is through a 'spy', Toba Singh, who misrepresents them to the Rajah. [Brian Houghton] Hodgson remains at Darjeeling to aid their communications & comfort Mrs AC. After Nepal, JDH hopes to visit Calcutta [Kolkata] or Bombay [Mumbai] before returning home in November.

Discusses J. D. Dana’s Geology [1849]. Pleased that the part on corals confirms his views [Coral reefs (1842)]. Discusses Dana’s observation that in Sandwich Islands lava streams often join dikes at right angles with no cone. Retracts earlier denial of this possibility. Criticises Dana’s view of Australian valleys.
JDH & Brian [Houghton Hodgson] [BHH] have both written to WJH about his situation. He explains the reason for [Archibald's] Campbell’s [AC] imprisonment: the Tartars & Bhothias believed that by capturing an authority they can bend him to their will. When this did not work, they invented offences in order to hold AC, but the Government have now intervened. The accusations are now of trespassing on the Thibet [Tibet] frontier. JDH & AC went there with the assent of the Chinese Lepchas & the Lachen Peppin who is the Sikkim authority. JDH’s Sirdars are in chains & his party disbanded, only Hopenar[?] remains. He discusses his seed collections & botanical matters, including Balanophora polyandra. The Nepal Terai is impassable until 15 Nov due to malaria & JDH will not travel to Calcutta [Kolkata] or Bombay [Mumbai] any earlier. [Nathaniel] Wallich will verify this. Lord Dalhousie will assist JDH & [Thomas] Thomson [TT] in applying to the Nepal Durbar. BHH is looking out for TT who has not yet arrived. JDH is glad Lindley liked his letter & thinks Klotzsch will make a mess of the collections of Prince Vladmier [Vladimir?]. With Wallich, Don & Hamilton working at cross-purposes, the whole Himalayan Flora is in the hands of JDH & TT. It can only be elucidated with Bogden & Wallich’s herbaria. JDH is sorry to hear of the Bishop of Norwich’s death & suggests Owen, if Brown will not take the position. Lord Derby was useless in the role. Bentham will offer sound advice. JDH discusses the wisdom of the Geological & Geographical Society in selecting men such as Hamilton, Lyle & Murchison.
