Same watermark (with countermark AI) as Mellon Ms. 79 (probably mid-1670s), the essay 'De ære et æthere' (date uncertain but definitely not before 1673), part of the 'Hypothesis' sent to the Royal Society in December 1675, and a letter to Hooke of the same month: see Shapiro, 'Dating Game', 195-6.

See Dobbs, Foundations, 132 for discussion of the sources and dating of this manuscript. Apart from the first two items, Newton could have taken all this from Zetzner's Theatrum Chemicum. The first five are all based on works of 'Philalethes'. Cf. also Keynes Mss. 14, 29, 36 and Yahuda Ms. Var. 259.
