List of plants found on the North West coast of Devon in the autumn of 1806: 'Hypericum androsaemum', 'Centaurea seabiosa', 'Scilla autumnalis', 'Ranunculus hederaceus', 'Papaver cambricum'; habitats and observations on each.

Arrangement [of his "Index plantarum" (1807)]. States that should he die before Smith his manuscripts and any part of his botanical library that Smith does not have will be his.

[Note in Smith's hand] "this proved, on enquiry after his death, to be altogether fallacious".

Aware that his support for the "gradual abolition of the slave trade" could be misunderstood by his friends, but meant it to ensure the slaves' saftey and interests and not for the benefit of the merchants. Finds it inexplicable that William Smith has lost his Norwich seat, as "the slave trade is held in such general abhorence" there, and he has been one of its "most firm & active opponents". Admires Smith's [epithet] for Alderman Baseley and praises Smith's "excellent turn" for this kind of composition. Details printing for his paper on Scitamineae. Intends to see [James] Sowerby about "Exotic botany", which must not be discontinued. Found a "Flora Peruviana & Chilensis" in [Henry Richard Vassall-Fox, 3rd Baron] Holland's [(1773-1840)] library containing figures of 'Canna', 'Costus', and 'Maruta', which he made copies of but forgot, and which confirm his and Smith's system [for determining 'Scitamineae' plants].

Regrets the "gross prurience of Linnaeus's mind" as seen in the several genera of 'Testacea' and the "vulgar lasciviousness" of 'Clitoria'. Considers Linnaeus' reasons for choosing the latter name 'Clitoria' and concludes that a literal translation of the first principle of Linnaean botany would "shock female modesty" and it is possible that many virtuous students might not be able to make out the similitude of 'Clitoria'. The name, like 'Chenopodium vulvaria', is "disgusting and horrid". Does not look at [Richard] Salisbury's publications and has not discussed anything with him since he and [Jonas] Dryander contended with his renaming 'Erica', including changing 'Erica tetralix' to 'Erica botuliformis' - sausage-shaped 'Erica'.

Admires Dawson Turner and asks Smith to thank him for his letter on '[Fucus] discors' and '[Fucus] abrotanifolius', hopes he and Smith will work out the essential difference between the two. [William] Hudson's specimen of '[Fucus] abrotanifolius' in his possession is the same as all the specimens found by Mrs [Ameila Warren] Griffiths [(1768-1858), algologist].

Disagrees with Smith's opinion that 'Cyamus' is the bean of Pythagoras his followers were forbidden to eat. Transcribes his account of the plant for Smith to either suppress it or alter it, presumably before publication, explaining his reasoning with detailed reference to Herodotus and Theophrastus. Asks whether he or Smith is to take 'Cyathea'. Comments on the 'Cyathodes laurina' mentioned in [Edward] Rudge's paper in the 8th volume of "Linnean Transactions", supposing it to be new. Enquires whether the rumours as to Smith's brother Frederic marrying a lady of his own acquaintance are true.

[Aylmer Bourke] Lambert unexpectedly visited but was in a peculiar mood and evasive regarding a promised visit to Smith in Norwich. Sorry to hear of [James] Crowe's death, said to be from a carbuncle boil. Lambert writes that Sir Joseph Banks is bedridden with a large abcess in his leg. Expects a contrast when either [George] Shaw or [Charles] Konig succeeds [Edward Whitaker] Gray [(1748-1806), physician and curator] at the British Museum. Shortly leaving for London.

Asks if Smith saw his letter in the Bury Paper of 21 January discussing mistletoe on oak; the man who first saw it surrounded by sycamores and maples loaded with mistletoe could not find it again, Cullum had intended to place an oaken bough with mistletoe on either side of the President's chair at Linnean Society meeting. Lambert took young plants of 'Holosteum umbellatum' and 'Sisymbrium polyceratium' growing near his house.

Delayed in responding to Smith by "extreme hurry & agitation" of his new employment [MP for Liverpool], from which he feels a "depression of spirits". Corrected sheets of his 'Scitamineae' paper but was unable to include plants from [Henry Richard Vassall-Fox, 3rd Baron] Holland's [(1773-1840)] copy of "Flora Peruviana".

Shares same sentiments as Smith on African slave trade and assures him he will not compromise; the bill is currently in the Lords, where if it passes its success in the Commons is guaranteed. Has not yet been able to visit [James] Sowerby. Unable to accept Smith's invite to Norwich as he must return to Lancashire.
