Forced to again delay his journey to London but intends to arrive in time for Linnean Society anniversary meeting. Anxious that Sir Christopher Pegge [(1764-1822), physician] be made part of Council, also suggests [Thomas Thynne, 2nd] Marquess of Bath [(1765-1837)]. Proposes Baron Alexander [von] Humboldt for FMLS, and either [Jean] Cuvier or [Augustin] de Candolle if there is another vacancy. Mortified to miss the dinner at Somerset Place [House, home of the Royal Society]. Necessary for [Thomas] Marsham to have repaid all his debt to the Society by the anniversary, or a considerable part with sufficient apology.

Leaving for London tomorrow and will attend Horticultural Society anniversary meeting and Linnean Society monthly meeting. Satisfied with Smith's explanation that [Arabella] Rowland's 'Brusenia' should have been Schreber's 'Brasenia'. Determined that the herb "scathery" is the winter or summer savory, in English called "saverye or saveraye", and in Dutch "saturey", and said by Gerard to be good eaten with "Beanes and Peason and other windie pulses" Ger.Em.p.577; this confirms Professor [Thomas] Martyn's observation in [Philip] Miller's "[Gardener's and botanist's] Dictionary" that winter and summer savory and other pot herbs must have been cultivated a long time before spices from the East Indies were in common use.

Glad none of Smith's relations were involved in the "dreadful catastrophe" of the exploding steam engine on the boat. Sorry for his friend Mr Davies' credit that he has not done anything generous for friends or relations in his will. Looking forward to seeing Smith in London.
