Excerpts from Nicholas Flammel, His Exposition of the Hieroglyphicall Figures which he caused to be painted upon an Arch in St Innocents Church-yard in Paris. Together with The secret Booke of Artephius, And the Epistle of Iohn Pontanus: Containing both the Theoricke and the Practicke of the Philosophers Stone. This English translation was published in London, 1624 and seems to have been Newton's main source. However, in the Pontanus letter he departs from the text of this edition at some points, possibly through reference to the Latin version in vol. 6 of Lazarus Zetzner's Theatrum Chemicum (1659-61: H1608): see Dobbs, Foundations, 130-31.

Reproduced with German translation and commentary in Karin Figala's unpublished thesis 'Newton als Alchemist' (Munich, 1978). See Dobbs, Foundations, 152-5 and 160-62 for a fuller description and arguments for the dating; also Figala, 'Exakte Alchemie', 179. H1192 is the Sendivogius work in question: for the rest of Newton's Sendivogius collection see also H445, 1131 (the Musaeum Hermeticum reformatum, which includes tracts by Sendivogius) and 1485 (but H445, a French version, post-dates these notes if Dobbs's dating is correct). H1311 is his copy of d'Espagnet's La philosophie naturelle. Further notes on Sendivogius in Keynes Ms. 55, Yahuda Ms. Var. 259.4 and Babson Ms. 925, Dibner Institute.


Annotated extracts from Michael Sendivogius and Jean d'Espagnet respectively. The right-hand half of each page consists of exegetical notes, which in the first set are headed 'Collectionum Explicationes', and in both cases take up rather more space than the original citations. f. 3v has the column headings 'Arcanum Hermeticæ Philosophiæ Opus' and 'Explicationes'.

Both verses are copied from Elias Ashmole's Theatrum Chemicum Britannicum (1652: H93), 421-2 and 278-9 respectively, though the notes on the 'Green Lyon', comprising elucidatory cross-references to other alchemical authors, would seem to be Newton's own. (Ashmole's edition does include notes on the work as an appendix, but they are completely different from those in this manuscript.)


'The standing of ye glass for ye time of Putrefaction & Congelation of ye medecine', in verse, 14 lines; 'The hunting of ye Green Lyon' (an extract), in verse, c. 180 lines; 'Notes upon ye hunting of ye green Lyon', c. 500 words.

Keynes Ms. 23 is a Latin translation of the French original of Didier's work. See Dobbs, Janus Faces, 180-81, and Westfall, Never at Rest, 529. Westfall argues that this manuscript and Keynes Ms. 53 represent the first steps, taken in the early 1690s, that led ultimately to the major essay 'Praxis' (Babson Ms. 420).

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.

Printed with an introduction in D. Geoghegan, 'Some indications of Newton's attitude towards alchemy', Ambix 6 (1957), 102-6 (Newton's text on 105-6); text also in NC, 4: 196-9. Cf. the variant version in SL46 (Joseph Halle Schaffner Collection, Chicago), and excerpts from Edmund Dickinson in Harry Ransom Research Center, University of Texas. See also Keynes Ms. 50 and Yahuda Ms. Var.259.


Begins: 'On Munday March 2d or Tuesday March 3 1695/6, A Londoner acquainted wth Mr. Boyle & Dr. Dickinson making me a visit, affirmed that in the work of Iodochus a Rhe wth [vitriol] twas not necessary that the [vitriol] should be purified but the oyle or spirit might be taken as sold in shops', and goes on to record the mystery visitor's account of his method of 'subliming' vitriol to produce a 'menstruum' that dissolves all metals.

Printed with an introduction in Churchill, 1967, q.v. for a discussion of sources and the suggestion that this is Newton's own translation. Dobbs (Janus Faces, 272) considers it to be a translation from the French Bibliothèque des philosophes (1672-8), and dates the translation late 1680s/early 1690s but considers the table of contents (f. 1r) to have been added in the late 1690s if not later. The main text (ff. 4r-12r) originally belonged after f. 2v of Keynes Ms. 28 (see Dobbs, Janus Faces, 272) but had been separated from it before the Sotheby sale, possibly by Newton himself. See H84 for Newton's copy of the Latin edition of the text, and H221 for his copy of the Bibliothèque des philosophes.


Translation [by Newton?] of a treatise on transmutation by 'Hermes Trismegistus'.

f. 1r 'The contents of ye 7 Chapters'.

f. 1v Brief Latin notes from Zetzner's Theatrum Chemicum.

ff. 4r-12r The translated text.

f. 12v Partial draft letter, undated and with no indication of addressee, on mathematics.

[64] 20 pp. on 12 ff. of which two blank.


mainly in English


Described in the Sotheby catalogue as '4 pp.', presumably meaning 4 written leaves, since all three parts of the document are listed there.


Transcribed with notes in Dobbs, Janus Faces, 271-7. She argues, mainly on the basis of the handwriting, that the document was composed as follows: f. 6r copied from a Latin version in the early 1680s, followed immediately or not long afterwards by what she considers to be Newton's own 'Commentarium' (ff. 6r-7r); the English translation (f. 2r-v) in the late 1680s or early 1690s (from French: cf. notes to Keynes Ms. 27) and the following annotations (f. 2v) later still, possibly even post-1700. These suggestions are repeated, with some modification, from her earlier article 'Newton's Commentary on the Emerald Tablet', which also includes a transcript of the English translation (183-4). See also notes to Keynes Ms. 27.

Another copy of the Latin text in Keynes Ms. 60, f. 6r. See H84.


f. 2r-v 'Tabula Smaragdina Hermetis Trismegistri [sic] Philosophorum patris': English translation of the Tabula Smaragdina followed by references to the 'ffrench Bibliotheque' [i.e. Bibliothèque des philosophes (1672-8): see notes to the previous entry] and Zetzner's Theatrum Chemicum.

f. 6r 'Hermes Trismegisti opera Chemica./ Tabula Smaragdina': the same passage in Latin.

ff. 6v-7r 'Commentarium': Latin notes on the above.

(ff. 1r and 5r both have the heading 'Hermes' but no text: according to Dobbs these were originally cover sheets for what are now the English sections of Keynes Mss. 27 and 28; the other leaves are blank.)

[69] 5 pp. on 10 ff.


in English and Latin


See Dobbs, Foundations, 131.


Begins with half a page in Latin on Hermes Trismegistus. Followed by English notes on the alchemical interpretation of ancient myths, then (ff. 1r-3r) Latin notes on a wide range of alchemical authors and myths, including references to Albertus Magnus, Flamel, the Rosicrucians, Lull and Geber. f. 2r has a diagram of a 'philosophical tree' taken from 'Anonymus Philosophicus Delphicus'. f. 3r has the subheading 'Aurum quot modis crescit & purgatur'. Concludes on f. 5r with 'Symbola 12 Sapientum': a list of the twelve sages who attend Maier's 'Banquet' together with their alchemical mottoes: they are Hermes [Trismegistus], Maria [the Jewess], Democritus, Morienus, Avicenna, Albertus Magnus, Arnoldus [de Villanova], Thomas Aquinas, Raim[undus] Lullius, 'Rocher [i.e. Roger] Bacon', Melchior [Cibinensis] and 'Anonymus Sarmata'.

Followed by related drafts and supplementary material, also in Latin, c. 5,000 words. Erroneously described in the Sotheby catalogue as 113 pp. + 49 pp.


Detailed account in Westfall, 'Newton's Index Chemicus'; see also his Never at Rest, 358-9.


The main text of the 'Index' appears on the rectos, with supplementary notes on the facing versos.

An elaborate alphabetical subject-index to the literature of alchemy, giving page references to over 144 different works, with several earlier and less elaborate drafts. In the most finished (though evidently incomplete) version (Ms. 30 a), the references are frequently supplemented by definitions of terms and processes or even short essays on the topic in question.

Ms. 30 a)

f. 1 An unrelated title page and table of contents which appears to have come astray (before the Sotheby sale) from Keynes Ms. 35: many though not all of the headings listed occur also in that manuscript.

f. 2 Title: 'Index Chemicus'. On the following folios (3-94), most head-words are followed by a definition and references, others merely by references, and a few by gaps to be filled in at a later date.

Ms. 30 b)

f. 1r 'Index Chymicus': alphabetical draft list of subject headings for the index, followed (ff. 2-5) by another index, much less developed than that in a) above.

Ms. 30 c)

Another draft 'Index Chemicus' on 12 ff.

Ms. 30 d)

'Supplementum Indicis Chemici' on 8 ff.

The remainder of these notes had become detached before the Sotheby sale and were sold, together with a separate set of notes on the same work, as SL41, which is now Babson Ms. 414 (q.v. for further details).


The complete text, i.e. Yahuda Var. 1 Ms. 30 and Babson Ms. 414B, is transcribed with very useful introductory notes in Dobbs, Janus Faces, 278-87. H1003 is Newton's copy of the French text.


Abstracts translated [by Newton?] from La lumière sortant par soy même des tenebres (1687), itself a translation of a Latin translation of and commentary on an original text in Italian verse possibly by Otto Tachenius. The commentary begins on f. 1v. On the 'grand mercury of Philosophers' and analogies between alchemical transmutations and the original Creation. Includes occasional elucidatory notes by Newton in square brackets.

[84] 4 pp.


in English


Discussed, with a transcript of two of the recipes and facsimile of the table of symbols, in Dobbs, Foundations, 137-8.


Seven pages of alchemical recipes followed by a table of (al)chemical symbols. Clearly not Newton's own composition though the source(s) has/have not been identified.

'Mr F' may be Ezekiel Foxcroft, Fellow of King's College and translator of J.V. Andreæ's Chymische Hochzeit: see Dobbs, Foundations, 111-12 (though the suggestion is disputed by Figala, 'Newton as Alchemist', 103). There is another reference to 'Mr. F.', unequivocally meaning Foxcroft, in 'De Scriptoribus Chemicis', Stanford University Library Ms.: see Figala et al., 'De Scriptoribus', 146-7. Newton's notes clearly date from no earlier than 1675 (the year in which the manuscript was communicated to him), and the handwriting suggests not much later: the preceding text could of course be earlier.


See Figala, 'Exakte Alchemie', 161, including a partial transcript of Newton's comments. A similar version of the text, but without Newton's additions and commentaries, was published by William Cooper in the anthology Aurifontana Chymica (London, 1680: H103).


A disquisition on the nature of alchemy, stressing that making gold is the most trivial of its aims. Followed by recipes 'To make all pretious stones better then the Natural', 'To make a Diamant', etc. On f. 5r, in Newton's hand, two further recipes under the headings 'Praxis Lapidis' and 'Multiplication', and then a series of notes on the foregoing text headed 'Here follow several notes & different readings collected out of a M.S. communicated to Mr F. by W.S. in 1670, & by Mr F. to me 1675'. Finally (f. 6r), 'An epitome of the practise of the work', also in Newton's hand.
