JDH is en route to Lachoong [Lachung] Pass but must first dry & send his plants to Darjeeling. He has many from the Lachen valley & wanted to stay longer despite the Rajah. [Archibald] Campbell [AC] writes of a lot of fever between there & Darjeeling but the Lachung road is safer. He wants Astragali, Cruciferae etc. from the Tibetan slopes or the table-land of Lachen. JDH took a Tartar pony up to 17000ft. He is now at 6000ft & describes the varied vegetation. He thinks the dangers are exaggerated, despite the discomfort of leeches. WJH’s letter arrived with PS from Lord Carlisle. He is glad the government has given up the Borneo grant. The Indian troops say Borneo is worse than Hindustan. [James] Brookes defends it only as a Naval depot. JDH is annoyed with AC’s politeness towards the Rajah; he had to rely on the Soubah’s help. JDH & AC also disagree about the location of the Tibet frontier at Neenla[?]. JDH will send seeds & roots of Jatamansi for the museum. Thomson is still at Simla [Shimla]. JDH will not take magnetic observations for the R.H.[Royal Horticultural?] Society unless Sabine sends the insgtruments. He dismisses the aneroid & would rather Newman send another small barometer. Muller has bought the instruments last sent; Hodgson also wants some as does Mr Middlesmiss[?] who cultivates tea at Khersiong. He congratulates WJH on Thwaites appointment & will write to him at Ceylon [Sri Lanka] about the importance of systematic botany & the 'Flora Zeylanica'. He is glad WJH has written to Jenkins & that Stevens does well. The seeds in Wallich’s letter were for WJH. He discusses the oaks & chestnuts there, his opinions on Spruce, Rhododendron formosum & the Palaeontographical Society. He will write to Bentham. JDH complains of Reeves, who has neglected sending copies of JDH's works. All India loves RHODODENDRONS OF THE SIKKIM-HIMLAYA. WJH should beware of Pentland who takes credit for Humboldt’s discovery.
