Thanks for turkey. Received letter and new work from [Augustin Pyramus] de Candolle who plans to come to England in May or June. Expecting sixth part of [Alexander von] Humboldt's "Nova genera et species", Humboldt planning to come to England in February. Asks after his paper on 'Cinchona' he sent Smith as he has additional observations to add.

Thanks for turkey. Pleased Smith's complaint is reducing but his measures not energetic enough; recommends 40 drops of laudanum a day, to add carbonate of ammonia to his camomile tea and tincture of 'Gentiana', to eat as much meat as possible, and to drink Bristol water, for several years.
