Has brought letters of [Peter] Collinson [(1694-1768)] and [Johann] Dillenius to Linnaeus for Nichols' inspection; approves of plan for making a separate publication of scientific letters. Hopes Nichols will be able to procure Miss Currer's [John] Ray letters. Uncertain how long he will remain in London, "the town air is always poison to me".

Has prepared the entire correspondence of Linnaeus and [John] Ellis [(1710-1776)] for the press, as well as [Daniel] Solander's letters to Ellis, [Peter] Collinson's [(1694-1768)], [José Celestino Bruno] Mutis' [(1732-1808)] from South America, and almost finished with Dr [Alexander] Garden's [(1730-1792)]. Asks to borrow Nichols' "Literary Illustrations" vol 1. Will prepare a short biographical memoir for each persons' letters, and will send a fragment of each hand for engraving. Thoughts on arrangement of volume. Expects to be in Liverpool from April till 20 May.
