Thanks for Smith's letter. Gratified that Smith accepted the portrait of his father [Johann Hedwig (1730-1799)] he sent, his loss; pleased Smith is using his father's classification in describing the mosses in "Flora Britannica" vol 3. Intends to request moss specimens from [James] Dickson from his new work, for his own continuation of his father's work on mosses, though he is struggling to find a publisher. Offers to send Smith moss collection. Has written a book on ferns after microscopic studies of many genera; would like it to be published and engraved in Britain; requests Smith's assistance; offers to send paper on ferns for Linnean Society.
