Still awaiting receipt of Australasian lichens and plants sent by Smith. Thanks for Smith's letter of 28 December 1801 and information on lichens.

Apologises for delay in sending this letter. Thanks for Australian lichens and volume three of "Flora Britannica". Responds to plant observations in Smith's letter with his own. Notes on classification method in "Annals of Botany" and new classification method for lichens. His lichen collection for Linnean Society contains 500 species, hopes to send it next year.
