Planning to come to London in April or May to attempt to settle at India House the remainder of his natural history collection and unless easily arranged "the whole for me may go to the devil". Hopes Smith received a copy of his "Hindu Genealogies".

His plans for visiting London. Hopes to procure for Smith duplicates and notes of his Indian plants which would make considerable additions to Smith's "Adversaria Botanica" which he hopes Smith will set about in earnest.

Having looked over the specimens obtained from India House has come to the conclusion that the most scientifically useful purpose would be to publish a commentaries on the "Hortus Malabaricus" and "Flora Amboinensis", details how he would go about this. Will start immediately if suitable for publication in "Linnean Transactions", with a supplement of the drawings from Mysore left with Smith and from Ava, Burma, given to Sir Joseph Banks. Drawings of 'Scitamineae' and Orchides have been lost by the Marquees of Hastings [Francis Edward Rawdon-Hastings (1754-1826) Governor-General of India, 1813-1823]. Requests Smith's opinion on this and whether it should be published all in Latin, or the commentary in English and the descriptive parts in Latin, as [Robert] Brown did in his treatise on the compositae in volume 12 of "Linnean Transactions".

Received Smith's letter of 26 August. Shall proceed with the commentary on the "Hortus Malabaricus", has started arranging the specimens and written a preface giving an account of his journeys in India but feels that the commentary will be of considerable length. Perplexed by a 'Boerhavia' which he previously thought a 'Valeriana chinensis', asks Smith to consult his Mysore specimens for a 'Boerharvia elata' so as to see if a mistake was made. Has found two species of Aspidium, one is 'Aspidium dilatatum' and the other he previously thought to be 'Felix femina' but now cannot identify despite consulting "Flora Britannica", sending specimens. Sorry to hear of [Robert] Brown's difficulties at the British Museum.

Sends the first part of his commentary on the "Hortus Malabaricus", if suitable for "Linnean Transactions" will forward the rest. The Wernerian Society in Edinburgh will print a similar commentary on the "Herbarium Amboinense". Arranging the dried plants he brought from India according to the Linnaean method and compiling an index, explains his methodology. Reports the progress of the commentary, having reached 'Hexandria' and already has 900 species. Would like to discuss with Smith what to do with specimen duplicates. Has sent an account of his botanical work in India to the Royal Society of Edinburgh which will form an introduction to his commentaries. Requests berries of the 'Viscum'.

Received Smith's letter of 13 April. Thanks for the mistletoe berries. A severe drought in Scotland has killed many young trees, herbaceous plants and crops "so that famine is staring us in the face". Working on his index and has now reached 'Didynamia' and 1500 species and has completed his commentary on the first part of the "Herbarium Amboinense" intended for the Wernerian Society in Edinburgh but despairs at their tardiness. Will continue his work on the "Hortus Malabaricus".

Thanks for "Flora Anglica". Making strong progress with "Hortus Malabaricus". Has given commentary on the first volume of the "Herbarium Amboinense" to the Wernerian Society in Edinburgh but doubtful whether it will appear. [William Jackson] Hooker is to compile detailed observations that are suited for neither commentaries and publish them in the Edinburgh Philosophical Journal. Complains that Venlenat, [Augustin Pyramus] de Candolle, [Carl Sigismund] Kunth "and other Goths are overwhelming us with new orders", which he believes [Robert] Brown may be "aiding and abetting", and that they do not understand the difference between an order and a genus as established by Linnaeus.

Thanks for third volume of "English Botany" although so engrossed with Indian plants unsure when he will focus on British plants again. Will send a copy of his commentary on the eighth part of the "Hortus Malabaricus", is making progress with copying the ninth part and writing the tenth, envisages the whole being completed in another year. Sends a copy of his "Indian Genealogies" for Smith's friend. Explains why he has used Latin instead of English botanical terms in his commentary. Outraged by the "monstrous innovations and unnecessary slang" lately introduced into the Linnaean language and the improper manner in which new names are being manufactured. Will soon see [William James] Hooker in Glasgow.
