Explains difficulties of making Smith an advance payment for his work on "Flora Graeca", principally being fear of Smith's death and its consequences for completion of the work. He and [Thomas] Platt [(d 1842), one of John Sibthorp's executors, supervised the publication of "Flora Graeca"] hope the work can be finished in the next few years by borrowing money from University of Oxford and limiting the number of copies made. Asks Smith to supply list of all of Sibthorp's provincial floras, taken from Sibthorp's journals. Executor of will of Mr Jones of Chelsea gives Smith permission to inspect the collections he had expressed an interest in.
