Responds to Davall's five letters [of 11 February 1791] and remarks further on plants sent by Davall on which their opinions differ. Thinks that Davall should either confide the Latin of his book to [Jacob] Wyttenbach, send his manuscript to [Samuel] Goodenough or himself, or communicate his findings in English to Linnean Society for second volume of "Linnean Transactions", so long as it appears in some form or other. Does not know 'Psora testacca' but Davall should keep it for his own work, as he would rather quote it from that to save himself trouble.

Sends £20 for [James] Sowerby to pay for plates, "Florists Delight", and "English Botany". Discusses 'Lachenalia mediana', 'Lachenalia pallida' and 'Hyacinthus orchidioides' with reference to [Nikolaus von] Jacquin's "Icones plantarum rariorum" and [William Aiton's] "Hortus Kewensis". Received visit from [Joseph von] Jacquin who criticised [Albrecht von] Haller [(1758-1823)] and [Jacob] Wyttenbach's "premature" proposal [for new edition of elder Haller's "Icones plantarum Helvetiae"] and thinks this may be why they gave it up. Jacquin also provided introduction to [Carlo] Allioni and had not heard of Smith's intended "Systema Vegetabilium", thinks Jacquin "a good young man" but the botanical chair of Vienna "thirsts for preeminence". Will endeavour to repair relations with [William] Aiton [(1731-1793)]. Has moved earth for 3-4,000 pots, fears his health will be ruined before garden comes to fruition. Intends to send 'Carex tomentosa' grown from root, and intends to grow 'Schoenus ferrugineus'.
