Thanks for Smith's letter of 2 March [1801] and 'Drosera' specimens. Botany has "afforded [him] a most agreeable relaxation" from more severe study; preparing fourth edition of his father's [William Withering] work ["An arrangement of British plants", first published 1776], though warns not much alteration or improvement can be expected; thanks for Smith's offer of assistance. Requests Smith's assistance regarding an "indifferent specimen" of 'Ranunculus gramineus' gathered in North Wales; observations, will send it. He recently applied to join the Linnean Society.
