Details reception of Roscoe's paper [on 'Scitamineae'] at Linnean Society; approved by everybody, especially [Jonas] Dryander, who has suggested some changes in terminology after he and Smith went through all the paper's references and specimens. [Aylmer Bourke] Lambert and [William Townsend] Aiton also praised it, though they are convinced Roscoe could not have had the knowledge and materials and that it was written by Smith.

Thanks for Smith's and [Jonas] Dryander's remarks on his 'Scitamineae' paper; plans to add some notes before it is printed and other corrections based on fifteen Scitamineae plants sent by Lord Seaforth [Francis Humberston Mackenzie] from Barbados. Details some of the corrections he is making for second edition of "[Life and Pontificate of] Leo [the Tenth]".

Returns his revised paper on 'Scitamineae'; details some of the changes including rearrangement of genus 'Canna' after observations and thinks all the varieties marked in "Hortus Kewensis" are distinct species. Has been making improvements to his lands and buildings since start of the year. Encourages Smith to investigate difficult genus 'Amomum'. Has no interest in critical reviews of "Exotic botany" and encourages Smith to continue it, thinking that it will "answer much better in the result" than "English Botany".
