Comments on criticism of his paper on 'Scitamineae' made by [Richard] Salisbury and Andrews in "Transactions"; the former spoke well of it except for the figure of 'Curcuma' but the latter was more rude with "much less reason".

Engrossed in politics and expecting to print new pamphlet shortly, but he does not enjoy it. Hopes Smith will establish "Exotic botany" properly; comments on its value as a "periodical vehicle for diffusing sound opinions & Linnaean principles, when they are so frequently disregarded or avowedly attacked", especially as "English botany" is finishing and never had a place for "more general observations"; believes that "heresies" in botany should be opposed by "orthodox doctrines", otherwise "the antipope Jussieu will dethrone our true Pontif Linnaeus"; criticism of Jussieu's system.

Visit by Mr and Mrs Martin [Smith's brother-in-law and sister] with "little Frederick"; pleased to hear Smith may visit Lancashire in near future.
