Has written to Duke of Gloucester [Prince William Frederick (1776-1834), chancellor of Cambridge University] and [Thomas] Creevey [(1768-1838), politician] in support of Smith's Cambridge candidature [for botany professorship]; does not doubt Smith's success. His knee recovering but cannot yet commit to a journey to Norfolk. Has ordered [William] Roxburgh's "Asiatic researches" paper on 'Scitamineae', in which he appears to have partially adopted his [Roscoe's] arrangement but without acknowledgement, and eleventh volume of "Linnean Transactions" containing his paper ['On Artificial and Natural Arrangements of Plants']; his concerns about the paper. Will look out Smith's biography of [José Celestino Bruno] Mutis [(1732-1808), botanist] in [Abraham] Rees' "Cyclopedia".
