Thanks for the very favourable review of "Flora Britannica" in the January issue of the "Monthly Review". Explains that there will be a longer delay in publishing the remaining volumes in order to compare Cryptogamia and fungus in [James] Dickson's "Cryptogamia", [Erik] Acharius' "Prodromus Lichenographiae Suecicae", and [Christiaan Hendrik] Persoon's "general work on fungi"; and have a further two seasons of spring to work on 'Salix'. Responds to remarks made in the review on nomenclature.
