Thanks Smith for specimens, including one from Linnaean collections. Requests specimens of 'Salix reticulata', 'Salix rubra', and others as he plans to study 'Salix' in the Fens this summer. Promises greater part of Smith's desiderata except for some plants from his "Flora [Cantabrigiensis]". Hopes he is a FLS. Asks if Smith's Cryptogamia is so complete as to not need his assistance.

Explains that the authority for habitats in "Flora Cantabrigiensis" and his supplements are all his, except 'Phleum paniculatum' which is on [James] Crowe's authority, and except for 'Salix rubra' found by [Samuel] Goodenough at Ely the other ['Salix'?] habitats are wrong. Lists two pages of new habitats for plants in "Flora Cantabrigiensis" for insertion [in "English Botany"]. Has sent [James] Sowerby and now Smith specimens of 'Potamogeton gramineum' and his Burwell plant, thinks it is the plant in "Flor. Dan. t.222" ["Flora Danica"?]. Lists two pages of new Cambridgeshire plants and habitats found since his last supplementum [over following two sides of the letter]. Commencing study of mints ['Mentha'], offers to send specimens of any not described by [William] Sole. List of plants sent, five are unnamed with habitats, but presumably 'Mentha'; plus 'Potamogeton gramineum', which Smith has annotated "only 'compressum'"; and possible 'Salix caprea', asks Smith to figure it if so.

Long list of specimens with habitats sent to Smith [possibly two different letters].

Appreciates Smith's proposal to add a footnote mentioning the republication of his "Flora Canatabrigiensis" when quoting from the same.
