A large notebook with the title “Adversaria physica 93” inscribed inside the front cover, as well as Locke’s shelfmark: 13/28a.

The notebook was originally used by Locke in his capacity as Secretary of Presentations to Lord Chancellor Shaftesbury (1672/3) for entering petitions for church livings (pp. 1-23); for similar papers, cf. PRO 30/24/42/59. After Locke’s return to England in 1689, he used the book for a catalogue of that part of his library which had remained in London during his exile in Holland (pp. 27-191). Finally, free space was used for medical and chemical notes, in the hand of Sylvester Brounower, with some additions and corrections by Locke.

2^o. 313 × 192 mm. ii, 55, 56-454 pages (pp. 222-454 blank; Locke wrote the page numbers on pp. 1-25 and on the rectos of pp. 27-55). The volume is bound in leather, with some blind tooling.
