Thanks for box of books, especially the [Leonard] Plukenet [(1642-1706), botanist], marbles and pebbles, and plant specimens. Discusses the specimens, including plants: 'Aralea', 'Sitbaldier', 'Acrostichum septentrionale', 'Gnaphalium alpinum', 'Silene acaulis', 'Empetrum nigrum'; requests 'Saxifraga nivalis', 'Saxifraga caespitosa', and 'Ranunculus reptens'; lichens, including: 'Lichen laratus', 'L. pubescens', 'L. plumbius', 'L. ventosus', and 'L. gildius'; gathered 'L. omphaloides', 'L. scrobiculatus', 'L. geographicus'; and 'Juncus', including 'J. spicatus', 'J. campestris', 'J. biglumis', also the 'Arundo epigeios' he sent Smith. Smith's 'Lycoperdon' is clearly new.

Charles Bryant [(d 1799)] published and dedicated his pamphlet to Sir Joseph Banks; thinks Banks cannot have read it as he sent a letter of thanks, and in doing so "prostituted his pen", especially as he is the "present head of English botanists"; Bryant's errors.

Lists his Lightfoot desiderata. Has not said anything on the mosses Smith sent; [John] Pitchford thinks Smith's 'Fontinalis pennater' is 'Hypnum crispum'. 'Fontinalis squamosa' or 'F. minor' appears to be 'F. antipgretica'.

Discusses the decocting of "red bark", possibly for agues: [William] Withering uses 'Salix alba', Smith recommends 'Salix myrsinites'. [John] Lightfoot says the 'Fontinalis pennata' Smith found is 'Hypnum complanatum'. Discussion of lichens: does not believe Smith's two 'Lichen parellus' specimens are distinct; agrees with 'L. pertusus'; Smith's 'L. gelidus' accords with Hudson ["Flora Anglica"] but does not think it distinct from 'L. ventosus'; mistakenly called 'L. fluviatilis' 'L. vivularis'; requests 'L. vespertilis', 'L. marginalis', and 'L. sylvaticus'; London botanists wrong about 'L. cristatus' and 'L. crispus', errors with Dillenius' plate of it; requests 'L. vernalis' of Lightfoot and 'L. fernugineus' of Hudson; Lightfoot's 'L. aurantiacus' is Hudson's 'L. ferrugineus' and not 'L. flavo-rubescens'; unsure what Lightfoot's 'L. vernalis' is in Hudson.
