Manuscripts/MS Add.3958-4007/MS Add.3974 contains:

Add.3974.1

Notes on Magnetism. From unknown source. The observations (some of which are erroneous) do not seem to be Newton's, though here and there remarks upon them seem to be his.
Creator: Newton, Sir Isaac, Knight, 1642-1727, natural philosopher and mathematician.
f.1 [quarto]; paper.

c 1670-c 1680

Add.3974.2

De natura acidorum. Copy of a paper "written by Mr Newton's hand".
ff.2 [folio]; paper.

c 1670-c 1680

Add.3974.3

Eleven Points for Enquiry in Physics.
Creator: Newton, Sir Isaac, Knight, 1642-1727, natural philosopher and mathematician.
f.1 [quarto]; paper.

c 1670-c 1680

Add.3974.4

De gemmis in genere. Notes, mostly from Berquen, Boethius, Tavernier and Boyle. Index of refraction in diamonds is given 41/100 on the authority of Halley. On p.3 is mentioned a very fragile and soft western Topaz which he found to have a specific gravity 4.27, though the sines of refraction were as 14 to 23 (could this be Baryte?). On p.7 he deduces from the cleavage that gems are crystallized like salts from juices which turn to stone. At the end are the gold and silver standards of different countries.
Creator: Newton, Sir Isaac, Knight, 1642-1727, natural philosopher and mathematician.
ff.12 [quarto]; paper.

c 1670-c 1680

Add.3974.5

De gemmis. Another version of parts of Add. 3974.4, with the addition (on f.1r) of a passage on reasons for thinking that diamonds are coagulated from a fluid and fat substance.
Creator: Newton, Sir Isaac, Knight, 1642-1727, natural philosopher and mathematician.
ff.4 [quarto]; paper.

c 1670-c 1680

Add.3974.6

Of Gems. English translation of parts of Add. 3974.4-5.
