Congratulates Smith on purchase of the Linnaean collections, which "will be a means of making [Smith] much know". Dined with [Thomas] Woodward and [James] Crowe, latter anxious for Smith not to make any agreements as to disposal of collections before speaking to him. Glad Smith has said the purchase will not interfere with his medical studies, as exclusive study of natural history can only be pursued by those with independent fortunes. Advises Smith to buy the herbarium of the younger Linnaeus if not included in the main purchase, for the duplicates. Will now regard Smith as "a second Linnaeus", though afraid Smith's other pursuits will not enable him to make full use of the collections. Opportunity for correcting Linnaeus' incorrect synonyms in "Species plantarum". Many made unwell by "this cruel winter".

Pleased to hear of safe arrival of Linnaean collections, Smith must have been made anxious by long delay in its coming.

His considerations and advice on Linnaean collections, following discussion with Smith's father [James Smith]: recommends Smith focus on his medical studies, and after arranging and cataloguing it to his satisfaction he should decide what parts, if any, to dispose of; if Smith intends to give lectures then neither the minerals, plants, or insects can be disposed of. Recommends caution on publishing new editions of Linnaeus' works from the manuscripts, and suggests publishing a "Flora Britannica" in "Linnaean dress", if Smith can obtain [John] Ray's plants or verify his synonyms. Danger if exhibiting the plants of being pre-empted in publication of new English plants.

[Richard] Relhan has gathered 'Athamanta oreoselinum' Hudson and named by him 'A. hibanotis'. Hudson has found 'Corrigiola littoralis' on Devon coast.
