Thanks Smith for revising his paper on 'Bertolonia'. Hopes Smith has received the other papers he sent on two new species of lobster; a new species of 'Echensis'; and a new species of tuber. Observes that "a sort of fatality" seems attached to [Franciscus] Cupani's "Panphyton Siculum", with Cupani, Bonanni and Chianelli, and now himself failing to finish their work on it; asks for Smith's assistance in getting it published in London. Asks whether any English publishers would take up three of his manuscripts: "Flora Sicula", "Sicilian Zoology", and "Critiques des Genres". List of nine botanical works he would like Smith to acquire for him.
