General regret at Dr Lubbock's departure from Edinburgh. Account of botanical expedition to Ben Lomond in the autumn, previously undertaken with Smith and Hardy, lists plants found, including: 'Lythrum salicaria', 'Lysimachia vulgaris', 'Sedum rubens', 'Telephium', 'Convolvulus sepium', 'Malva moschata', 'Scirpus maritimus', 'Ruppia maritima', 'Lobelia dortmanna', 'Isoetis sacustris', and bark of 'Osmunda regalis'. Asks if Smith has ascended the highest English mountain, in "Yorkshire", as he intended. Comments on 'Cynosurus caerulens'. Comments on the "pompous" Dr Samuel Ferries, who has moved to London from Scotland.
