The first section is another commentary on Ripley's 'Gates', similar in construction to Keynes Mss. 51 and 53 but quite different in content, and this time covering all twelve 'gates': in addition to the six mentioned above under Keynes Ms. 51 there are cibation, sublimation, fermentation, exaltation, multiplication and projection.

The 'Notes upon Ripley' represent, in Dobbs's words, 'Newton's study of Philalethes' comments on Ripley' (Janus Faces, 122, n. 1). See also Keynes Mss. 17, 51, 52, 53.
