Sends draft of his paper [on 'Scitamineae']; if Smith agrees with principal points he can improve it with Smith's herbarium and library. Comments on a "sullen & ungracious" critique of his "[Life and Pontificate of] Leo [the Tenth]" in the "Edinburgh Review", pointing out its errors and his determination to respond to the "volumes of abuse". Pleased by Mr Reeve's "favourable opinion" of the book.
