Has not heard from Smith for two years; uncertain if the Linnean Society has received his papers on genus 'Bertolonia', genus 'Callitriche', and descriptions of two new genera of 'Crustacea' and new species of Atlantic fish. Enquires after the bill he sent Smith with which to purchase and send him new natural history books. He has also sent the first volume of a scientific journal he has been publishing since the start of the year as well, but hearing no answer supposes it not acceptable. Encloses several pamphlets. Regrets that their correspondence is not more active. Wishes to know if "Flora Britannica" vol 4 and "Prodromus florae graecae" vol 2 are published.
