Queries on his 'Ulva' paper for Smith to resolve. Arrangements for visit by [James] Sowerby and commissions for drawing 'Fucus' species. Received [Samuel] Goodenough's articles for their paper on 'Fucus', which he generally praises, except that his Latin can run into the "oratorical style"; further notes on composition and contents of their paper. Can acquire coins for Smith. Asks if plan respecting Smith's brother, John, [to emigrate to America] is arranged, after seeing report that some people of large fortune who emigrated from Birmingham have been taken prisoner by a French frigate during their passage.
