Sending seeds of 'Morus satarica', 'Morus anhubrida', 'Rheum caspidum', and 'Pallaspier caspica', from Taurida, Crimean Tartary, that he was sent by [Peter Simon] Pallas of St Petersburg. Has received some "curious specimens of new manufactory" including a felt hat made from the down of 'Typha angustifolia' or 'Palustres' and hare fur. A useful discovery as he had been unaware that even a proportion of vegetable matter could be felted and believes that similar use may be made of Smith's "silky cottons" from Sierra Leone and short cotton wool of the West Indies. Also received a "kind of wadd" made from 'Typha', "light as a feather and extremely warm if quilted between folds of cloth". Believes a similar effect could be achieved with with long, feathery seeds from Sierra Leone.
