Since JDHs last letter from Aden they have been on the Indian Ocean, the most uninteresting sea he has crossed. Sighted Cape Comorin last Thursday & landed at Point de Galle on Friday, a few hours after the 'Precursor'. Thought of FH & English friends on Christmas day. Describes the 'Moozuffer' as more like a yacht than a man of war. Lord & Lady Dalhousie are in the Captain’s cabin whilst he, Fane, Courtenay & Dr Bell are in the ships dirty armoury next to the engine. Indian Navy officers do not like ships being used as passage boats. JDH met a godson of FH’s father, Lieutenant Jermyn. At Ceylon [Sri Lanka] JDH again saw Matilda Rigby who left Colombo where James Smith’s house & property is. JDH finds Lord & Lady D extremely agreeable but indifferent to science. Notes the cuisine as odious. Lady D’s health is better & soon after arriving her father, Lord Tweeddale, Governor of Madras [Chennai], came on board in a grand party. JDH will leave Madras on Friday morning & go to Calcutta [Kolkata]. He has not made many sketches since leaving Cairo, he was too busy botanising in Aden. Nearly all his collections have been destroyed from salt water on board ship. His spare papers were also destroyed so he could not collect at Point de Galle.

JDH has corresponded with Robert Wight regarding the address of Mrs Wight, currently in Scotland. Baillieu or Arnott may have more information regarding Mrs W. JDH asks for some things he forgot to be sent out to him via the Cape, incl. Lindley's THE VEGETABLE KINGDOM, his testimonials, Humboldt's letter & a copy of the RBG Kew guide. He refers to the Ladakh mission in Tibet. JDH is struggling with names of common plants that are unfamiliar to him. He discusses the Agri-Horticultural garden in Madras [Chennai] and the man who runs it, an amateur gardener: Captain Worcester who will send RBG Kew roots of mango trees, Notheria, Orchideae & palms as he is doing for Loddiges. JDH considers Walter Elliott the best man in Madras, he is knowledgeable about mammals & birds.

JDH describes his arrival at Madras harbour with Lord Dalhousie [James Andrew Broun-Ramsay], his daughter [Lady Susan Georgiana Hay], [Colonel Francis William Henry] Fane, Courtenay & Bell. They were met by the Marquis of Tweedale [George Hay] of whom JDH expresses a very low opinion, & later given a grand oriental welcome including large crowds, a military reception & bands playing God Save the Queen. JDH describes Madras, government house & his stay there & his opinion of the people he stayed with & encountered, including: ladies Tweedale & Dalhousie; Lord Arthur Hay, a collecting naturalist; Lord Dance; Major Garsten, previously of Abercrombie Place & now resident at the Court of the Nabob of Arat; General Cubbon, political agent for Mysore; Cubbon's surgeon who knew about cotton growing in the hottest parts of India; Mr & Mrs Walter Elliott, collectors of antiquities; & the Wedderburn's, friends of Matilda Ripley[?].

JDH mentions his preparations for onward travel: securing Giddy's collector and looking for servants to employ. JDH also describes some street performers & a levee presided over by Dalhousie. JDH spent most of his time at the Horticultural Society Garden. From Calcutta [Kolkata] JDH writes that he values Bessy's letters, is plagued by mosquitoes, met Robert Reddie & plans to go to Midnapore & Burdwan with Guney[?].

JDH gives his opinion of John McClelland [JMC], his efforts to prepare William Griffith's [WG] work for publication & the changes he is making to the East India Company Botanical Garden, Calcutta [Kolkata]. Mentions four monuments in the Garden: to General Kyd, to Roxburgh, to Jack & to Griffith & some of the most beautiful plants: palms, mahogany, Terminalis, Naucleas, DIllenias & Tectona grandis. Government are nervous about the management of the Garden as Nathaniel Wallich [NW] was not cooperative as Superintendant . JDH is hopeful for the Garden under Hugh Falconer. JDH is complementary about WG's drawings, which are being lithographed & comments on the extent & quality of his writings & maps. WG's published work will represent mosses & Hepaticae, grasses & Cyperaceae, other phaenogamae, & new or rare species, not ferns. WJH should have got WG's fern specimens from Bootan [Bhutan], Mishmee [Mishmi] & Ava[?]. JMC is also lithographing a Wallich catalogue. Gives his opinion of WG.
