The first, primarily optical, section of the manuscript (to p. 22) is discussed in A.R. Hall, 'Further optical experiments of Isaac Newton', Annals of Science 11 (1955), 27-43, and transcribed in McGuire and Tamny, Certain Philosophical Questions, 466-89. Article 64 (on the optic nerve) was first published (with due acknowledgment) in Joseph Harris, Treatise on Optics (1775), 108-10, with a copy of the diagram in the plate following p. 110, and again from Harris's edition by Brewster (1855), 1: 432-6. Several extracts from the following pages printed in A.R. and M.B. Hall, 'Newton's chemical experiments'. Experiments on pp. 45-6 printed in Brewster (1855), 2: 366-7. pp. 81-2 printed in Dobbs, Foundations, 249-50. See also H254-H276 for Newton's extensive Boyle collection.
