Hopes JH can attend council meeting on 7 July. Thinks Kew Observatory could be made an important magnetic and meteorological station.

JDH reports progress on NIGER FLORA. He thinks Napoleona is close to Gustavia, it resembles an Indian Lecythis. [Nathaniel] Wallich sends JDH news. Ava trip postponed in favour of Darjeeling. Spring flora incl.: Convallariae, Apris, viola, Oak, Chestnut, Magnoliae, Arums, Fragaria, Rhododendrons, Prunus, Pyrus & Rosa with Clematis, Gentiana, Umbelliferae, Begonias, Saniculas & autumn vegetation to follow. Insects incl. Cocinillae & Grylli. Political relations with Bootan [Bhutan] & China mean JDH probably cannot go to Thibet [Tibet] via Kumaon or any other route. At Darjeeling it is not possible to see the different flora of the low valleys during the rains. Sir F. Currie sanctioned [Thomas] Thomson's [TT] continued work. JDH hopes TT measured the height of Gilgit. JDH is collecting for the museum & Jenkins at Goalpara has some things. Discusses the palm-like plants at Darjeeling, the rattan is used to make bridges & wild Musa leaves to carry things. Explains what collections, incl. from Borneo, he has promised to share with the Calcutta Garden. [Hugh] Falconer's [HF] health is improving, he will forward JDH's Bhangulpore [Bhagalpur] plants to Kew along with first shipment of roots incl. Balsams & Gesnerioids. JDH now likes HF but still has a low opinion of Royle. The collectors JDH sent to Tonglo were stopped at the border, they should be allowed to cross but Campbell the political resident does not enforce such rights. Further discusses British relations with the Rajah of Sikkim, position of Lord Dalhousie & permission to visit the snows. Mentions native people of Sikkim: Tartars, Lepchas, Tibetans, Murinis, Limbos & Bhutanese. JDH travelled to Darjeeling via Benares from hence he will go to Assam via Gowahatty & visit Sadiya in the Mishmee [Mishmi] Hills, the tea plantations & Ava. Would like to go to Tibetan passes. Comments that Madden is a good botanist. JDH is doing sketches & writing up his journal & geographical & botanical observations of the Himalayas.
