Footnote
First edition, one of 30 copies on large paper, of Bacon's chief work, edited by Samuel Jebb from the 16th century Trinity College manuscript, which was believed at the time to be the only complete manuscript copy. Subsequent discoveries revealed a seventh part, first published in 1860. Inserted between parts IV and V is a separate treatise ‘De multiplicatione specierum’. Bowyer's ledgers show ‘220 copies printed on crown and 30 on royal’ (ESTC).
