JDH thanks Humboldt for mention in ASPECTS OF NATURE. JDH mentions his imprisonment by the Rajah with [Archibald] Campbell. He writes regarding geography of the Himalayas. He discusses heights of certain peaks determined by the Surveyor General & Captain Thullier & also determining elevation using native & cultivated vegetation as indicators, e.g. at Lhassa. He describes the location, extent & nature of mountain groups with reference to landmarks & some mention of the different people, vegetation, snowline & climate. His description covers: Chumalari, Kinchin-Junga [Kanchenjunga] between rivers Teesta & Arun, Dwhalgiri [Dhaulagiri], Gossain-Than between Gundule & Gogra, Jewahir, a group dividing Soubansiri & the Morass, Patchion Valley, Donkiah between Matchoo [Mo Chhu] & Lachen, Mansarovar, Kamtchoo[?] Lakes, U & Tsang provinces, Dingchaun Province, Ramtchin, Kiong-lah range incl. Odoos & Mateltons, Yarou river, Mendoling & Darjeeling. He discusses the boundaries of Nepal, Tibet, Sikkim, China & Bhutan mentioning Puri.
