Encloses specimen of 'Gymnostomum donnianum' [extant], named by Dr [James Edward] Smith and to be included in "English botany" for next April, also encloses a magnified drawing of it and letter from the artist [both extant]. Asks Brodie to transmit the whole to Smith. [Dawson] Turner thought it the 'Grimmea pusilla' of "Flora Britannica" but after examining five hundred specimens he is sure it is not.

Letter from James Neill, Lauriston Road, to George Don, Edinburgh, 12 February 1806: describes how he drew the magnified drawing of 'G. donnianum' with a solar microscope, a method he believes is new. Pencil drawing of 'G. donnianum' and specimen of same, wrapped in paper.

Note by Brodie to Smith on cover, forwarding the whole.
