Thanks for plants; had previously received some of the species from Nepal through [Nathaniel] Wallich, but unnamed. Comments on inconveniences of this "place of banishment", particularly there being no botanical library but his own, nor any botanical friends to consult with. Asks Smith to remember him should he receive interesting specimens; in return sending copy of his "Musci Exotici". Asks if he sent 'Lyellia crispa', and if Smith has seen 'Primula scotia', to be figured in "Flora Londinensis". Blackwood of Edinburgh keen for him to publish a periodical on exotic botany ["Exotic flora"]; requests access to [Francis] Buchanan's East India drawings.

His students have increased by 18 compared to last year, a total of 75 though only 52 were paying students. Expects [Robert] Graham [(1786-1845)] at Edinburgh to make over £1200 from his [botany] professorship, besides his practice as physician; they have formed a new garden of 14 acres, with stoves and greenhouses. Death of Dr Stuart.

Difficulties in communicating with Smith. Concerned to find that expressions of his in "Flora Scotia" have been misconstrued as attacks on Smith; will ensure offensive passages are expunged from second edition; apologises for and explains his wording of pages 132 and 279; praises Smith's botanical skills. Discusses differences in leaf shape of 'Salix purpurea', 'S. helix', and 'S. amygdalina'. Disagrees that economical merit should give place to scientific character in reference to 'S. caerulea', discusses authors on 'Salix' including Candolle and Sprengel.

Criticises [Samuel Frederick] Gray's "Natural Arrangements of British Plants", which seems "calculated to give the death blow to the study of natural orders, if not to botany altogether", remarks on plant names and attack on Linnaeus in preface, thinks [Richard] Salisbury has assisted with the natural orders. Refutes Salisbury's article on [Jonas] Dryander in October "Monthly Review".

Hopes Smith's work on "English Flora" in earnest; if Smith had declined it would have undertaking it himself. Return from his professorship not enough to support his family; supplementing by publishing books; proposes a "Species plantarum" in English, though concedes it would largely be a translation of Candolle, asks Smith's opinion. His intended "Exotic botany" work delayed by lack of able Scottish artists; difficulties with publisher. Thanks for duplicate specimens.
