JDH comments that he has received some corrections from [Miles Joseph] Berkeley but does not think that the number of errors justify the printing of a new page. Berkeley's manuscript was illegible, JDH had to make a new copy & look up species names in [Elias Magnus] Fries. Berkeley's corrections are generally not good, those he did for THE LONDON JOURNAL OF BOTANY contained many errors. Mentions that a paper Berkeley produced with Montague contained 70 mistakes. JDH finds it curious that [William] Wilson & [Thomas] Taylor were pleased with the work when JDH added a great deal to both of their contributions, at least Berkeley's work is his own. JDH is pleased that his father has 'weathered upon' [Lovell] Reeve, the publisher, & that the [BOTANICAL REGISTER] is coming to an end. JDH is trying to write an introduction to FLORA ANTARCTICA but he is very caught up with lectures. Discusses the series of lectures he is giving at Edinburgh [University], he does not use the useless material he is given but speaks freely rather than reading & it engages his students. He has or will cover the subjects of plant physiology, nutrition, circulation, life, irritability, respiration the Linnean system & the origin & distribution of species; he finds the last a particularly challenging subject. [Gilbert] McNab arrives in London soon. Asks that Bessy [Elizabeth Hooker] give [Joseph] Dayman their copy of FOLIA SYBILLINA. JDH has heard from Dawson [Dawson William Turner?], who is going to Yarmouth. JDH has left letters for a Mrs Sprot & Admiral Tait. JDH mentions other people that he still has to call upon in Edinburgh including the Gibsons, Craigs, Mackes, McKenzies, Kays & Fullertons. Comments that Dr [Robert] Graham is still ill.

JDH informs his father, Sir William Jackson Hooker, about developments in his candidature for the Chair of Botany at Edinburgh University, usually held by one person unifying the posts of College Professor, Regius Professor, & Curator of the Botanic Garden. He reports that [John Hutton] Balfour had previously refused to take the post of Chair without the garden curatorship leaving only JDH & Leller[?] as candidates. JDH is Crown nominated & has the support of the University Provost but needs approval from the Town Council. The Natural History Chair also needs dual approval, the Provost plans to petition Sir James Graham [Home Secretary] to relinquish all Government, or 'Crown', control over 1 chair in return for total control of the other, plus his guaranteed support for JDH's candidature. JDH does not think this will be well received as the government has put a lot of money into the college & botanic garden. JDH adds that Balfour has since revoked his conditional refusal of the post of Chair of Botany without the garden curatorship, & the Town Council is inclined to appoint him if only to demonstrate their influence to government. They also want someone with lecturing, not just botanical, credentials. JDH is dismissive of their opposition, if he got the posts of Regius Professor & Garden Curator the faculty would have to accept him. Only the College Professorship is in the gift of the Town Council, it would be the post devalued & JDH would be happy to free of it & the Council's oversight in exchange for the reduced salary. He concludes that it has all become a matter of politics. One Councillor suggested that JDH take Balfour's current position at Glasgow claiming it was of equal value, JDH disabused him. JDH mentions some people he has seen, or expects to soon, in Edinburgh: Nicoll, the Gibson Craigs, Deucher[?], Muir, Henderson & Smith, the Sands & Lord Falnor[?]. He also has invitations to Kilmun, Riccarton, the Smiths at Coulston, E. Hendersons & the Gardens.

JDH writes from Lisbon regarding his journey, letter sent with one to Miss Henslow. Anticipates good passage as far as Sidon but plans after reaching Egypt are uncertain, he will stay close to G.G.

Reports on progress with V.D.L. [van Diemen's Land] plants to be sent home by Dr Salmon, not Miller, along with the with the Niger m/s [manuscript]. Provisionally calls the new V.D.L. cruciferous plant Bretonia. This & the Fagus called ‘gunnii’ from the m/s of Gunn’s trip should be checked by Pl[anchon?] to see if names are occupied & characters drawn up. Dr Richardson to be informed what ship the plants are sent on so he can send case of bottles by the same via steamer to Barnes. JDH to write again from Gibraltar with account of Lisbon.

In another letter JDH will show how the physical geography has indicated the positions of the tribes of people as well as plants, & has regulated their migration. Spent a long time with WE at botanic garden under care of Captain Worcester'. Describes garden.

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 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. JDH recounts a discussion with George Gardener about why WJH fell out with Fielding. Discusses: his supplies, including paper; the transportation of live plants to India for Sir L. Peel; & material for the Niger Flora. Mentions Mr Philips, Lord Auckland, Mr Colville, Mr Brown, Aunt Palgrave, Colonel Lawrence political resident at Lahore & Sir H. Willock.

He hopes to get an Amherstia. JDH will go to Darjeeling in Mar. JDH conveys what he knows about members of the Ladakh expedition: Major Cunningham, Strachey & Thomas Thomson.

JDH was staying with Sir L. Peel then at Government House with Lady & Lord Dalhousie. JDH is now travelling with Mr Williams' camp & was supplied for the trip by Sir James Colvile; nephew of Lord Auckland. JDH travelled Dawk: by Palanquin, from Calcutta [Kolkata] via Hooghly & the McIntosh's house at Burdwan to the camp at Taldangah where he met Mr Theobold & F. Watkins.

JDH explains the process of collecting & drying plants whilst with Williams, including drying paper used, the weather pattern & why it is the wrong season for collecting. Dryness in India means few Epiphytal Orchideae, ferns & Cryptogammia except Riccia. Other plants collected incl.: Vallisnera; Villarsiae; Potamogetons; one fungi, an Agaric; a Fissidens moss, few lichens & no Hepaticae. He describes an aboriginal bellows made of leaves procured for the Kew Museum, at fairs he buys boxes, beads & medicines. Roberts gave samples of cultivated grains. JDH critiques work done on the Calcutta [Kolkata] Botanic Gardens by William Griffith[WG] & Robert McLelland [McClelland] & outlines changes he advised Hugh Falconer make.

At Dinapore [Danapur] missed Captain Hemchman but met Captain Doria. At Patna stayed with Irvine who went with WJH to Slaffa & collected Fucus balticus; visited the opium factory & got a set of their tools; met a son of Admiral Beaufort & through him heard of Mrs L.P. Wilson’s death. In India JDH is known from James Clark Ross's account of their voyage. Thanked Lord Dalhousie for appointing Gurney. At Morghyr he & Dr Hastings visited hot springs where they worship the Confervae, could not collect them as at Sarroukbund. At Bhungalpore [Bhagalpur] staying with Grant & Raikes, has met Clergyman Vaux & written account of Major Napleton's horticultural garden for JOURNAL OF BOTANY, the curator is named Ross.

He anticipates luxuriant flora at Darjeeling. JDH prefers up-country India to Calcutta [Kolkata]. Mentions Thomas Thomson, Vicary, MacIvor in Madras [Chennai], Brewster's article in the N. BRITISH REVIEW, Lord Morpeth, Mr Phillippe, Lord Auckland, Lawrence Peel.

An account of the geology & vegetation in Indian Plains JDH traversed with Mr Williams' Geological Survey. Area covered was south of the Ganges along the Grand Trunk Road & Soane River encompassing Rotas Ghur & Bidjegur [Bijaigarh] hill forts, the Kymore [Kumaon] & Vindhya hills, Parasnath, Hooghly, Burdwan, Taldangah, Dunwar Pass, Bind Hills, Sultanganje & Calgong, Chunar Rock, table lands of Berbhoom [Birbhum] & Behar, Mirzapur & Bhangulpore [Bhagalpur]. Describes the topography of the landscape & common rocks incl: granite, Hornblende schist, sandstone, quartz, coal nurseries & limestone. He travelled through plains & wooded hills. Comments on extent of mountain ranges in India, one immense range comprising the Rajmahals & Sylhet hills, another the Kymaon [Kumaon] & Vindhya hills, which bounds the Soane & Nerbudda & stretches to the Arabian Sea. The positions of these ranges influence vegetation. The alluvium & kunker which covers everything, the uniform dry climate & flat land exposed to desert winds from Hindustan & solar radiation also determine vegetation. Vegetation lacks variety because of these factors, which override the influences of altitude & latitude; forms are found indicative of altitude in the Nilgherries [Nilgiris] & Ceylon. Flora is less luxuriant beyond the Ganges delta with fewer palms & grasses & more thorny shrubs. The richest areas: Parasnath & upper valleys of the Soane have only a few spp of tree, unadorned with moss or lichen. Bamboo & Ramin replace the Urticae & ferns of moister areas. Timber trees higher up are: Terminalias, Bassia & Diospyros. Lower down are mangos, Tamarind, Figs & Acacias. Soil sterility & aridity limit species of tree: Boswellia, Stercutis, Euphorbiae, & Cochlospermum gossypium will grow in rocky places, some flourish better than others but not depending on rock type. Moister climate nearer Bengal means more luxuriant flora marked by coconuts at Patna & reduction of Acacia arabica at mouth of the Soane.

JDH is sending WJH part of Niger Flora to be proofed by his mother, Jules Émile Planchon & George Bentham. Since last writing JDH has been over Darjeeling border into Sikkim, against orders of the Rajah, & to the border of Bootan [Bhutan]. He found: Cycas, India rubber tree, & Phoenix. As route descended, European genera such as: Oak, Maple, Birch, Alder Hydrangea, Violet, Hypericum & Rubiaceae became: Araliaceae, Alsophila, Urticae & scandent Leguminosa & at still lower altitude: Shorea robusta, Cedrela toona, Dalbergia sissoo, Alstonia, Pinus longifolia, Saccharum, Sterculia Fici, Rubiaceae, Gnetum etc which continue to the plains. JDH is drawing interesting plants, incl: Paris sp, Stauntonia, Convallaria, Chrysosplenium, Coptis, Sanicula, Magnolia & 3 Rhododendrons incl. a beautiful one with sweet scented white blooms. Palms are limited, Arums superb, one flowered in his tent & gave off significant stench & heat. Plans to go to Nepaul [Nepal] border & a hill only previously climbed by Captain Waugh of the Trigonometric Survey. Describes weather. Is sketching Himalayan landscape. Has found wild banana & orange. Is collecting woods & implements incl. cups made from knots of trees, a silver dagger from a Tibetan Lama, & a rosary made from amber, Cornelian, agate & vegetable beads. Not yet season for grains. Bamboo is staple product. Describes hard working Lepcha collectors & compares to lazy Bengalis. Discusses money affairs incl. salary & dealing with Barclay & with Findlay's house: McVicar Smith & Coy of Calcutta [Kolkata]. Will stay with Brian Houghton Hodgson; oriental scholar & zoologist. If allowed JDH will travel to Sikkim snows, if not to the Barrampoota [Brahmaputra], Assam & Sadiya & ascend Dapha Bum mountain. Will visit Jenkins at Gowahatty [Guwahati] & the Tea districts, Mopling fir forest, Cossya [Khasi] hills, Cherra Poonjee [Cherrapunjee] & Munneepore [Manipur] in Ava. Once back from Tongolo JDH will send live plants via Hugh Falconer at Calcutta.

JDH recounts his excursion to Tonglo Mountain, the plants observed & the collections made. Explains that cold, wet weather made many of his servants sick & unable to work. The most hard working were his Christian servant Clemanze & the Lepchas. Describes habits of Lepchas. Tonglo is 1000ft higher than JDH has been before, this was reflected in vegetation: Iris, Unciniae, 2 Arums, 2 dwarf Panax, Anagallis, Rannunculus, Aconite, Rhubarb, Thalictrum, Convallaria, above them the dwarf Bamboo forming a little jungle, Rosa, Lonicera, Holboellea, Vacciniae, Arbutus, Currant, Rubus, Daphne & Balanophora. Describes 3 new Rhododendrons & promises drawings & plants sent via Calcutta [Kolkata]. He is very keen to get them to Kew. Also collected: a Yew, scarlet Crategus, Rosa, Pyrus, Prunus, Pyrus, 3 Berberis, Wallich's Kadsura grandiflora & an epiphytic orchid. Describes new purple Magnolia. There was no grass & few ferns, lichens & mosses: Cryptogams poor in general. Got no seeds but will return. Has temperature readings for Lindley. Describes sojourn in Lama village, he stayed in the temple & observed the priests' rituals, then ate fermented barley from a woven bamboo bowl. Mentions types of bamboo grown & many useful items made from it, which he is getting for the Kew museum. Also has samples of cloth dyed with Mungeet, indigo & Elaeocarpus. Collectors have returned from Nepal, beyond the snows, where the flora is very different despite the proximity. Most of their collection is rotten, a Frittilaria & a Primrose may survive. JDH will send more collectors, relationships with China & border powers mean he may not be able to go himself despite the efforts of his political friends: Colville, Dalhousie, Elliott & Falconer. Has Carices for Boott & fungi to draw for Berkeley. Mentions: progress on the NIGER FLORA, Rose of Jericho, news of Tussack grass, observations for Humboldt, constant rain, general features of Himalayan botany & adds the letter shld be sent to Darwin at Down.

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.

Via Calcutta [Kolkata] JDH has sent: end of NIGER FLORA, sketches, incl. many Rhododendrons, list of roots sent to RBG Kew & sample of Lepcha Boehemeria cloth. Discusses navy half pay & difficulty getting items of economic botany for the museum, he has cotton cloth & baskets & awaits bows, arrows & quiver. Mentions specimen of only large spadixed palm. Has completed [River] Soane journal & discusses publication of it by WJH & The Asiatic Society, a copy shld be sent to Robert Chambers' Journal to promote the expedition. Advises that roots sent to Sir L. Peel by Smith shld be packed better, likewise bottles sent to JDH. JDH will send home extensive collection of dried herbarium specimens on leaving Darjeeling for Mr Jenkins' in Assam, after the rains. Mentions expenses & living with [Brian Houghton] Hodgson [BHH], whose only neighbours are: Dr & Mrs Archibald Campbell [AC] & the Muller brothers, one of whom works at the Patna opium factory, the other at Calcutta mint. JDH still hopes to go North & visit the snows: border issues with Sikkim& China are complex & he is being assisted by AC, Lord Dalhousie & Colonial Office. JDH wants new species named after Mrs Campbell & Lady Dalhousie, WJH may re-name the rest. Has drawn Phaenogams &, for Berkeley, fungi. Found new Balanophoras sp. & prepared dissections for THE LINNEAN SOCIETY TRANSCATIONS. Promises descriptions of Magnolias. Mentions: assistance provided by Gurney, HF lecturing, writing to Stocks, BHH's sister Miss Colville to visit RBG Kew with Miss Edens, defending [Nathaniel Wallich], Madden's TENTAMEN FLORAE NEPALENSIS, Col. Lawrence , Griffith's synonymising, falling out with Brown over Rafflesia & fossil cones, a phosphorescent fungus resembling Belcher's Borneo one. Heard of Col. Waugh, Surveyor General, measuring Kanchenjunga as the highest mountain in the world. JDH has a view of it, one of the true Himalayas of the Chamalari rising from the plain of Tibet. Possible that Dawalgiri in Nepal maybe taller.
