Contents

a) f. 1r Copy of a recipe for multiplying silver (by adding silver, antimony and lead to cinnabar).

b) ff. 2r-5r Notes on 'Aqua Sicca', 'Aquila Iovis' and 'Sceptrum Iovis', with repeatedly reworked recipes for preparing these substances, accompanied by annotations either in parallel columns or at the foot of the page.

c) ff. 6r-8v Notes and recipes derived from an unidentified source, with rough sketches of furnaces and calculations.

Section b) is analysed in detail by Dobbs (Foundations, 167-75), who regards it as 'of extraordinary importance for a study of his [Newton's] alchemical methodology' (ibid., 168), being Newton's attempt to elucidate the symbolism of John de Monte Snyders' The Metamorphosis of the Planets (see Newton's transcript of this text, Cushing/Whitney Medical Library, Yale University). See also the notes on Snyders in the Rare Book and Manuscript Library, Columbia University.
