Davall is in danger of relapsing and overstraining his eyes: prescribes half an ounce of camphor dissolved in half a pint of rectified spirit of wine for bathing the temples; "an admirable thing for strengthening the eyes". Thanks for packet of plant specimens, 'Ribes petraeum' "surely right". Lady Rockingham sends Davall a large paper copy of his "Icones pictae" and invites him to see her 'Portlandia'; it frequently exhibits fifteen flowers "in full perfection" besides buds. Pleased Davall refused to allow his plates to go to [Jacob] Wyttenbach [for new edition of Albrecht von Haller's "Icones plantarum Helvetiae"]. Thanks for 'Schoenus ferrugineus'. Confirms Davall's order for Sowerby for coloured plates of 'Limodorum' and 'Strelitzia' and drawing of Miss Lee's 'Protea'. Editing a new edition of "Flora Lapponica" for White & Son, shall add new plants and put the trivial names to all, the original plates bought in Holland. Desires Davall's opinion of new number of "English Botany", currently writing it anonymously to gauge reaction but thinks it excels [William] Curtis' "Botanical Magazine" and it may also hurt Curtis' "Flora [Londinensis]" if he does not exert himself.
