JDH had letters about [George] Gardener's death & his collections from Dr Fleming of the army in Ceylon [Sri Lanka] & from Wight. Clamanze has arrived with JDH's collections at the Calcutta Botanic Gardens, where Falconer is expected. JDH discusses the uncertain route of his Sikkim expedition & if he will be hindered by the Rajah & the Lasso Kaji: the lately rejected Vakeel, who could stop JDH crossing the Teesta. JDH's party comprises soldiers, [Brian Houghton] Hodgson's shooters, Lepchas, Sikkim Bhoteas. [Archibald] Campbell came as far as the Great Rungeet. JDH discusses his new servant's faults & the hospitable Cathcart. The ship 'Malabar' bringing Adye's instruments has reached Calcutta [Kolkata]. JDH mentions Captain Mac Luckie's account of a sea serpent in the ILLUSTRATED LONDON NEWS, identified by Prof Owen as a seal. Discusses some barley, the health of Thomas Thomson, & Wallich & McLeland's quarrels reported by Dr O'Shaugnessy. Further up the mountain JDH has collected: a yellow Cymbidium; a funny tree resembling 'Putraajira', which he will identify using Endlicher's book; & Wallichia. This letter will be taken to Dajeeling by Tcheba Lama. The Rajah has sent Hooker his old guide Meepo.
