Requests specimens, presumably collected during Smith's northern tour, of 'Juncus spicatus', 'Juncus biglumis', 'Juncus triglumis', 'Gnaphalium supinum', 'Anthericum calyculatum', 'Salix lapponum', 'Polytrichum alpinum', 'Lichen polyphyllos', 'Polypodium rhoeticum', and a fructifying 'Lichen fasciularis', some are marked in pencil with a cross. Has sent a specimen of 'Lichen parellus' that may differ from Smith's. A list of plants he has found in the summer. Turnip crop in Norfolk devastated by black caterpillars, has been unable to find the fly that produces them, but [Eleazar] Albin's "A Natural History of the English Insects" relates how a similar blight in 1719 was caused by the 'Ichneumon' fly, which Bryant disputes. The only flies collected from the turnip fields are possibly the 'Tenthredo rosae', sends two specimens for Smith for information and asks which fly Albin's black caterpillar produces.
