Content: ROBERT BOYLE'S `HEADS' AND `INQUIRIES' Edited by Michael Hunter Robert Boyle Project Occasional Papers No. 1
Robert Boyle's `Heads' and `Inquiries' This publication makes available hitherto unpublished material by Robert Boyle (1627­91) in the form of the sets of `heads' and `inquiries' that he devised, a key part of the inductive method that he developed on the basis of that of Francis Bacon (1561­1626). Following Bacon, Boyle used such lists as a means of setting himself an agenda when studying a subject, for organising data and for soliciting related information from others. The documents in question cover a fascinating range of topics, from luminosity and elasticity to anatomy and the incidence of disease. They throw important light on Boyle's scientific interests and method. The editor, Michael Hunter, is Professor of History at Birkbeck, University of London, and Director of the Robert Boyle Project.

Introduction This is an edition of a distinctive group of documents surviving among the Boyle Papers at the Royal Society, with ancillary items from other repositories, notably the Locke Papers in the Bodleian Library. These exemplify a method for collecting and organising data which Robert Boyle adopted from the 1660s onwards. Further examples of the genre are to be found in Boyle's published writings, both the influential sets of `Heads' and `Inquiries' that he produced for Philosophical Transactions in the 1660s, and the lists of `Titles' that he deployed to structure a number of his major works, from New Experiments and Observations touching Cold in 1665 to the posthumous General History of the Air of 1692.1 As has been argued more fully elsewhere, this was a genre that Boyle derived from Francis Bacon, and his new-found enthusiasm for it in the 1660s seems to have been due to the influence of the Royal Society in its early years.2 There is a striking absence of evidence of Boyle's use of such `heads' in his earlier writings, which are more discursive in structure. The significance of the 1660s as the time when he adopted the genre is underlined by various pieces of evidence. It was now that he published such lists to a disproportionate extent, especially the Philosophical Transactions items already referred to. Even some of those published at a later date seem to trace their origins to this decade. In addition, the hitherto unpublished documents presented here survive in handwritings of the 1660s to a disproportionate extent: 1660s material is relatively rare in the Boyle archive as a whole, yet, of the documents of this type surviving in the archive, thirteen out of seventeen are in 1660s hands. What is more, these frequently show evidence of revision during composition, thus confirming that they were newly compiled at that time. Of course, not all are of this date: a number are in later hands (though, strikingly, none is in an earlier one). It is clear that, just as Boyle continued to use such lists as the structure for published works for the rest of his life, so he seems to have continued to have had such lists compiled or recopied in manuscript. It is unfortunately often impossible to tell whether documents in later hands are copies of ones originally compiled earlier, or whether they originated at the time when they were written. In at least one case (doc. j, pp. 17­19) there is evidence of later composition or revision, but in others recopying seems likelier. It is perhaps worth noting that, to a disproportionate extent, it is the documents in later hands that have the most explicitly Baconian titles (see docs j, k and r, pp. 17, 19, 33), echoing the revived interest in the genre which Boyle appears to have taken in connection with the preparation of Human Blood for publication in the early 1680s.3 The documents give an extraordinary insight into Boyle's intellectual agenda, and the way in which this was informed by his curiosity and his philosophical acumen. They are extremely rich and vivid in terms of the information that they give about phenomena which interested Boyle and the ways in which he suggested that these 1 See esp.Works, vol. 4, pp. 226­7; vol. 5, pp. 508­11, 527­40 and 544­6; vol. 10, pp. 12­ 16, 220­4 247­9; vol. 12, pp. 7­8. 2 See Michael Hunter, `Robert Boyle and the Early Royal Society: a Reciprocal Exchange in the Making of Baconian Science', British Journal for the history of science, forthcoming. 3 See Harriet Knight and Michael Hunter, `Robert Boyle's Memoirs for the Natural History of Human Blood (1684): Print, Manuscript and the Impact of Baconianism in Seventeenthcentury Medical Science', Medical History, forthcoming. vii
INTRODUCTION might be investigated. They range from the theory of matter and the investigation of topics like elasticity or luminosity to anatomy and the incidence of disease. As already noted, they reflect Boyle's intellectual inheritance from Francis Bacon, who had seen the preparation of `Particular Topics or Articles of Inquiry' as central to the enterprise of natural philosophy. In Boyle's case, such lists of `Heads' or `Titles' might be used either as a framework for organising data, as in such published works as his Cold (1665) or his General History of the Air (1692),4 or as an agenda for collecting information, as in his `General Heads for a Natural History of a Country, Great or small' or his `Articles of Inquiries touching Mines', both published in Philosophical Transactions in 1666.5 As represented here, the genre is disproportionately aimed at eliciting data through experimental inquiry. The documents contained in this volume vary markedly both in their range and in the amount of detail they give. Some are hardly more than lists. Others are much more discursive and elaborate. And, whereas some deal with quite a specific set of phenomena, others range more widely, perhaps particularly the one dealing with the `Natural History of the Sea' in all its aspects. It is also worth commenting on the way in which the `Heads' are presented. Sometimes entries begin `Of', as if they are going to be descriptive, sometimes `Whether', as if they are interrogatory. This reflects the ambivalence between `Heads' and `Inquiries' in the title of the genre which Boyle inherited from Bacon, and, to an extent which we may find slightly strange, both men seem to have seen the two as interchangeable. Though those who study the documents presented here and compare them with the published examples already itemised will have no doubt about the distinctive character of the genre and its direct links with the Baconian precedents to which Boyle explicitly declared himself indebted, it has some slightly grey edges. Firstly, there are summaries of the content of proposed books which sometimes seem superficially similar, in that they often set out a series of statements, sometimes accompanied by a list of instances: these go back to much earlier in Boyle's career and continue thereafter. Early examples include `Of Publick-spiritednesse' from the 1640s or `Of Natural Philosophie' of c. 1650, while from the 1660s we have the plans for the unpublished parts of The Usefulness of Natural Philosophy, or for the attack on orthodox medical practice that Boyle drew up at that time, or the synopsis on the complementary nature of reason and revelation that has recently been published in full by Jack MacIntosh.6 The difference between the two genres is signalled by the fact that such documents usually comprise a set of propositions introduced by `That', in contrast to the more interrogatory `Whether' or descriptive `Of' which characterises the documents presented here. There is also an element of overlap between the documents printed below and more basic lists of experiments or of things to remember that Boyle compiled, which often give a list of phenomena, each preceded by `Remember'.7 Both types of document are fascinating and richly deserving of study, but they are essentially separate from the `Heads' and `Inquiries' dealt with here. This edition also excludes examples of the genre that were published in or shortly after Boyle's lifetime, either in 4 Works, vol. 4, esp. pp. 226­7, vol. 12, esp. pp. 7­8. 5 Ibid., vol. 5, pp. 508­11, 529­40. 6 See Works, vol. 1, p. cxii; Scrupulosity and Science, pp. 30­1; Works, vol. 13, pp. lxiii­lxx; Scrupulosity and Science, pp. 167, 187­9; J.J.

INTRODUCTION Philosophical Transactions or in his own books; extant manuscript material linked to these published texts is also excluded, since it is tabulated in full in The Works of Robert Boyle.8 Lastly, by definition only texts which are extant can be included, whereas it is clear from the inventories of Boyle's papers made by Henry Miles c. 1740 that further specimens passed through his hands which are no longer extant. These include `Titles' for the natural history of common salt, for example, or `Heads' for the natural history of gold or of the tides, none of which is otherwise known.9 Interestingly, in a list that Henry Oldenburg compiled of Boyle's unpublished writings in 1677, he included `A Book of Schemes and Queries relating to Natural philosophy', `In a Marble-paper Cover'.10 This is no longer extant in that form, but it may be argued that the present volume goes as far as is possible to reconstruct an otherwise lost work by Boyle. The texts are presented in the order in which they appear in the Boyle Papers (or, in cases where multiple versions survive, at the point where the copy text appears), with documents from other sources at the end. In the brief introduction to each document which follows, a Standard Format has been deployed: the title is followed by information on the source, on handwriting and date, and on the physical characteristics of the document. There is then a more discursive note on the document, including information on previous publication where appropriate. a. `Experiments about Volatile Salts', pp. 1­2 BP 10, fol. 5. Hand: Slare. Date: c. 1670. Written on the recto of a single leaf; verso blank. Throughout, where `V.S.' is used, it has been silently expanded. There are no clear clues to the date of this text, other than from handwriting. Though it bears a general relationship to the Producibleness of Chymical Principles of 1680, Boyle specifically refers to a lost paper on the history of volatile salts in Human Blood.11 b. `Magneticall Tryalls (made & to be made)', pp. 2­3 BP 10, fol. 57. Hand G. Date: 1660s. Written on the recto of a single leaf; verso blank. Endorsed opposite the first line of text: `Tbd'. This fairly spare document sets out an agenda for experiment on magnetical phenomena of the kind which Boyle was to implement both in his workdiaries and in such published works as chapter 1 of Experimenta et Observationes Physicae (1691).12 8 See esp. Works, vol. 5, pp. xxxv­vi, 529­40, 544­6; vol. 10, pp. xi­xv (see also Michael Hunter and Harriet Knight (eds.), Unpublished Material relating to Robert Boyle's `Memoirs for the Natural History of Human Blood'', Robert Boyle Project Occasional Papers, No. 2, 2005); vol. 12, pp. xi­iii, xv­xviii, xxiii­iv. 9 See Michael Hunter and Lawrence M. Principe, ``The Lost Papers of Robert Boyle', Annals of Science, 60 (2003), 269­311, on pp. 299 (nos. 23, 35), 300 (no. 46), 303 (no. 91), 304 (nos. 115, 127), and 308 (no. 203). All these are in Miles' list of `Titles'. 10 Works, vol. 14, p. 338. 11 Works, vol. 10, p. 39. 12 Works, vol. 11, pp. 377­84. For the workdiaries, see www.livesandletters.ac.uk/wd. ix
INTRODUCTION c. `Experiments to be made in seald Receivers', pp. 3­4 BP 10, fol. 118. Hand E. Date: 1660s. Written in two columns on the recto of a single leaf; title written across entire page; verso blank. The letters given in square brackets at the end of entries are pencil endorsements entered in the margin. Most entries are crossed through piecemeal in pencil; those that are not are marked *. This is another fairly straightforward list which includes various experiments published by Boyle, including ones in `Light and Air' (Phil. Trans., 1668), `Respiration' (Phil. Trans., 1670), 'Of the Difficulty of Producing Flame without Air' and 'Of the Difficulty of Preserving Flame without Air' (Flame and Air).13 It may be referred to by Oldenburg in a letter to Boyle of 3 December 1667.14 d. Untitled heads on elasticity, pp. 4­6 BP 10, fol. 132. Hand F. Date: 1660s. Written on both sides of a single leaf. Boyle refers to a treatise on the mechanical explanation of elasticity in Spring of the Air (1660), in Defence (1662) and in First Continuation (1669), where it is described as `Notes about the history of Elasticity'.15 These heads evidently relate to this otherwise lost work. e. Heads concerning Tastes, pp. 6­7 BP 10, fols 133v­4. Hand F. Date: 1660s. The title is written across a double-page spread, with the text beginning on the lefthand opening and continuing on the right. The recto of the first leaf and the verso of the second is blank. This and the next item, which survives adjacent to it, may be examples of the `speculations' that Boyle disavowed in favour of `matters of fact' at the start of `Mechanical Production of Tastes' in Mechanical Qualities (1675­6).16 The document lays out a full agenda for work in the field. f. Heads concerning Odours, pp. 7­9 BP 10, fols 135v­6. Hand F. Date: 1660s. The title is written across a double-page spread, with the text beginning on the lefthand opening and continuing on the right. The recto of the first leaf and the verso of the second is blank. See previous note. This document also lays out a full agenda for work in the field. Note the `Desiderata in the History of Odors' at the end. 13 See Works, vol. 6, pp. 11­13, 251­4; vol. 7, pp. 87, 97. 14 Correspondence, vol. 3, p. 373. 15 Works, vol. 1, p. 166, vol. 3, pp. 117, 123 and vol. 6, p. 77. 16 Works, vol. 8, pp. xxix, 365. x
INTRODUCTION g. `Anatomical Experiments to be try'd', pp. 9­12 BP 18, fols 129­30. Hand F. Date: 1660s. Written on two (now) separate leaves, which were perhaps once conjugate. The final three paragraphs are written in the margin at right-angles to the main text This important document lays out an agenda for dissection experiments, discovering what treatment would stimulate convulsions and other effects. Some of its prescriptions are quite elaborate. It is clearly linked to the work of the Oxford group, though the actual experiments involved are not otherwise documented.17 The final sentence should be noted. h. `Enquirys and Experiments about Electricall Bodys', pp. 12­15 BP 22, pp. 197­200, and BP 38, fol. 120. Hand F. Date: 1660s. Written on all four sides of a conjugate pair of leaves, and continuing on a single leaf, ending part of the way down the verso. The first two item are numbered `1' and `2', but this is not sustained and has therefore been ignored here. This is clearly linked to Boyle's `Mechanical Origin of Electricity' in his Mechanical Qualities (1675­6); in addition, `my Notes about Electricity' are referred to in First Continuation.18 The first section only was printed in M.B. Hall, Robert Boyle on Natural Philosophy (Bloomington, 1965), pp. 252-5. i. `Concerning shining Wood', pp. 16­17 BP 25, pp. 392­3. Hand E, changing to hand F at p. 393 (also making an addition on p. 392). Date: 1660s. Written across a double page spread, with the recto of the first leaf and the verso of the second blank. In two columns, with that under `Observations to be made' blank except for the keyed addition to the main text. Entry numbers subsequently added in pencil, in an order differing from that in which the entries were written. The entries have been reordered to reflect the numeration: entries nos. 10 and 11 originally appeared after the unnumbered entry between 3 and 4, with 11 preceding 10, and 12­14 between 17 and 18; the unnumbered, deleted entry between 12 and 13 has been moved with the group of which it forms part. This document is evidently that referred to by Boyle in `Light and Air' (Phil. Trans., 1668) as a place where he had proposed various trials of this kind, one of which he there exemplified.19 This item (which spawned a series of ancillary experiments) was therefore deleted from the list while the rest remained and were renumbered as described above. Oldenburg had referred to Boyle's `Queries' on the subject in various letters in December 1667.20 17 For background, see Robert G. Frank Jr., Harvey and the Oxford Physiologists: Scientific Ideas and social interaction (Berkeley and Los Angeles, 1980). 18 Works, vol. 6, p. 172. Cf. ibid., p. 175 (`My Observations about Electricity'); see also Effluviums, ibid., vol. 7, p. 262. 19 Ibid., vol. 6, pp. 3­25, esp. p. 5 20 Correspondence, vol. 3, p. 373. Cf. ibid., pp. 376, 380. xi
INTRODUCTION j. `Titles or Topica Particularia about the Natural History of Water', pp. 17­19 BP 26, fols 49­50. Hand: Bacon. Date: 1670s­80s. This is a conjugate pair of leaves, with the verso of the first and the recto of the second blank, probably because it has been bound into the volume the wrong way round: i.e., fol. 50v precedes fol. 49r. A further, slightly different version survives in BP 25, pp. 264­5, and the differences between the two have been noted in footnotes. Hand: Bacon. Date: 1670s­80s. This is a very general synopsis. No obvious context is apparent either from Boyle's published works or his papers. The differences between the two versions suggest that Boyle continued to work on it at this time. k. `Titles and Articles of Inquiry in Order to A Natural History of the Sea', pp. 19­23 BP 26, fols 51v­2: Hand: Bacon. Date: 1670s­80s. Written across a double page spread, with the recto of the first leaf and the verso of the second blank. The numbers are written in ink and are integral to this copy. Various commas were added in darker ink. Boyle supplied `Other Inquiries concerning the Sea' for Philosophical Transactions in 1666, in connection with which Oldenburg noted that Boyle `had not left unconsidered the Natural History of the Sea', possibly referring to an earlier version of the agenda represented here.21 l. Untitled heads concerning light and luminosity, pp. 23­4 BP 26, fols 62. Hand: Bacon. Other copies survive in BP 26, fol. 70, and BP 36. fols 98 and 99 (two copies). All copies are on rectos only with verso blank. All are in Bacon's hand. Trivial differences of orthography, etc, between the different versions have been ignored. In contrast to `Shining Wood' (above), this document represents a more general agenda concerning light and luminosity. m. `Enquirys about Lime', pp. 24­6 BP 26, fols 75­6. Hand F. Date: 1660s. Written on a conjugate pair of leaves. Verso of second leaf blank. This is another example of a rich research agenda for which there is no obvious context in Boyle's extant remains. 21 Works, vol. 5, p. 527. xii
INTRODUCTION n. `Enquirys & Tryalls about Insects & Spontearta', pp. 26­7 BP 26, fol. 90. Hand F. Date: 1660s. Written on both sides of a single sheet. This item is referred to in a letter from Oldenburg to Boyle dated 24 February 1666.22 It clearly relates to Boyle's concern with spontaneous generation, as recently studied by Peter Anstey.23 o. `Queries about Gems', pp. 28­30 BP 27, pp. 331­2. Hand: Oldenburg. Date: 1660s­70s. The text appears on pp. 331­2; pp. 333­4 is a conjugate leaf, but is blank except for Wotton's endorsement on p. 334: `Queries concerning Gems drawn by Mr Boyle. writt in Mr Oldenburghs Hand'. In general terms, this obviously relates to Gems (1673). It offers a very detailed set of inquiries, ranging beyond that work, though it is possible that it may relate to the various lost writings on related topics to which Boyle refers in Gems. 24 The fact that it is in Oldenburg's hand means that it must date from before 1677, but the date of the original from which it is derived is unclear. p. Untitled heads concerning copper, pp. 30­1 BP 36, fol. 80. Hand: Bacon. Date: 1670s­80s. Written on a single leaf; verso blank. `C' expanded to `Copper' throughout. This is perhaps to be compared with the work on tin published in vol. 14 of the Works.25 There are many references to copper scattered through Boyle's writings. q. Inquiries concerning Valentine Greatrakes, pp. 31­2 BL 3, fols 33­4. Hand F. Date: 1666. Written on a conjugate pair of leaves, of which the final verso is blank except for the endorsements, the first two in Boyle's hand: `Enquirys about the Stroker', `Enquirys about Mr Greatraks' and `papers of Mr Boyle one about Greatrix' (in pencil). In this document, Boyle applies his method to a specific case, that of the Irish healer, Valentine Greatrakes. The queries were probably written at an early stage in Boyle's interest in the affair. His own investigations of Greatrakes' healing powers are recorded in a workdiary and other sources.26 The inquiries were previously published in R.E.W. Maddison, The Life of the Hon. Robert Boyle (London, 1969), pp. 124­6, and in C.S. Breathnach, `Robert Boyle's Approach to the Ministrations of Valentine Greatrakes', 22 Correspondence, vol. 3, p. 80. 23 Peter Anstey, `Boyle on Seminal Principles', Studies in History and Philosophy of Biological and Biomedical Sciences, 33 (2002), 597­630, esp. pp. 614­19. 24 Works, vol. 7, pp. 3­72, passim. 25 Ibid., vol. 14, pp. 133­43. 26 See Workdiary 26 at www.livesandletters.ac.uk/wd; A Brief Account of Mr Valentine Greatraks (London, 1666), pp. 43ff.; and Correspondence, vol. 3, pp. 93­107, 160­1; vol. 4, pp. 98­103 xiii
INTRODUCTION History of Psychiatry, 10 (1999), 87­109, on pp. 97­101 (with a facsimile of the manuscript). r. `Prжliminary Topicks or Articles of Inquiry, in order to The History of Diseases', pp. 33­34 British Library Sloane MS 2502, fols 1v­2. Hand: Bacon. Date: 1670s­80s. Written on a double-page spread, the accompanying recto and verso of which are blank. The numeration and all the square brackets except the opening brackets under nos. 1 and 2 are added in pencil. This is clearly Boyle's own copy: it presumably reached its present location through Birch. There is a copy by Locke in Bodleian Library MS Locke c. 42 (part 1), p. 98, headed `82' and `Morbus': Locke's copy lacks the numeration and the square brackets, except the opening ones to entries 1 and 2. Its capitalisation and punctuation display minor differences which have not been noted here. This is an otherwise unknown reflection of Boyle's medical interests. It clearly relates to the interest in the relationship between disease and mineral deposits and airborne particles discussed in Boyle's `Salubrity of the Air', appended to Languid Motion (1685), and other works. The text is printed in Patrick Romanell, John Locke and Medicine: A New Key to Locke (New York, 1984), pp. 102­3, where it is wrongly presumed to be by Locke. The inclusion of descriptive matter at the end of each entry, here enclosed in square brackets in pencil, parallels Boyle's practice in some of his book synopses (see above, n. 6). s. Untitled heads concerning flame and fire, pp. 34­6 Bodleian Library MS Locke c. 42 (part 1), fols 266­7. Hand: Brownover. Date: 1682 [i.e., for Locke's copy]. Endorsed by Locke at head: `82' and `Flamma'; also endorsed `Flamma' at the head of p. 267 and `Mr. Boyle' at end of the last entry in Locke's hand. The numbering was added in pencil subsequent to the original transcription of the manuscript. It should be noted that Brownover evidently twice initially mistakenly transcribed the abbreviated form of `Whether' as `What', after which he gives it in unexpanded form from no. 36 onwards. Here, all instances of this have been expanded as `Whether'. This is evidently linked to a lost work by Boyle: extant fragments from a dialogue on this topic dating from the 1650s are printed in Works, vol. 13, where the relationship between this and later writings by Boyle on related topics is discussed.27 t. 'Queries about Damps', 36-7 From Oldenburg to Lister, 11 September 1675, Bodleian Library MS Lister 34, fol. 35. The letter as a whole is printed in Oldenburg, vol. 11, p. 489­91. A Draft Version, also in Oldenburg's hand, survives in Early Letters H.3.36. Verbal 27 See Works, vol. 13, pp. xliv­vi, 259­69, esp. p. xlv. xiv
INTRODUCTION differences between the two versions are noted here, but minor differences of spelling and punctuation have been ignored. For the genesis of these queries, which were compiled by Boyle in conjunction with Oldenburg after being requested by Lister on behalf of the virtuoso, Francis Jessop, in a letter dated 28 July, see ibid., pp. 433, 488­9 (details of the related letter in EL H.3.36 are given in ibid., p. 489). They are clearly linked to the `Articles of Inquiries touching Mines' published in Phil. Trans. in 1666 (see above, n. 1), but they were independently compiled at a later date. Boyle discusses the issue of damps in mines at various points in his writings. xv

Whether an Animall fed from the beginning with nothing but one sort of Insects, or the Body, whose putrifaction produced it, will thereby when dead afford the like Insects, or have that which it would naturally have producd considerably varyd.165 Whether in case Insects be produced in the Receiver they will have their motion as in the free Aire, notwithstanding that Insects of all sorts166 (except one) that I have tryd, will be renderd movelesse tho not kild167 by the withdrawing of the Aire, and this is particularly to be tryd in the Eggs of Snailes, for I have found by Experiment both that those Eggs being carefully kept will hatch of themselves, and that snailes tho bred in the free Aire will168 alone claim their motion in the exhaustd Receiver and if169 Flies & Butterflies & gnatts will be generated there, which not170 withstanding the exhausion of the Aire they will be able to fly. /fol. 90v/ Whether Froggs spawne will be hatchd in the exhausted Receiver, which171 would be as probable a way as any I can yet think of to try whether an Animall endowd with Lungs, may by assuefaction from the very first, be brought to live without Aire. Whether by mingling the juices of Herbs, or otherwise compounding vegetable substance[s] there will emerge upon the putrifaction of the mixture Insects of a compounde[d] Nature, or of a Neutrall Nature, or whether noe Insects at all will be producd. Make the like Tryalls with172 mixtures made of Animall & Vegetable substances, as of Blood and the juices of Herbs, to which sort may also belong Milk, Butter, Cheese, & severall kinds of Dungs, as that of Doggs fed only with bread &c. Whether Eggs putrifyd will produce the same Insects as Herbs, and the spawne of fishes, & other viparous Creatures, as the Animalls themselves. The like may be tryd with the Eggs of silkwormes, Catarpillars, & other Insects. Whether digestion of173 the matter to be putrifyd in a gentle heat will hinder the production of Insects, or will varie those that shall be producd. Whether Insects themselves174 as Worms, Catarpillars & others of the more juicy sort being well beaten into a Masse or Pap will upon putrifaction produce Insects & whether of the same kind or others, and if any whether this second-brood, being handld after the same maner, will afford a third, and How 175 this successe will hold, & in what creatures it will terminate. 165 This paragraph appears in the margin. 166 followed by `that I have tr' deleted. 167 followed by `with' deleted. 168 followed by `not' deleted. 169 followed by `Bees & B' deleted. 170 accidentally repeated. 171 followed by `will be a way to try' deleted. 172 followed by `the' deleted. 173 altered from `digesting'. 174 followed by `are' deleted. 175 replacing `many' deleted.

`HEADS' AND `INQUIRIES' o. Queries about Gems (BP 27, pp. 331­2) Quer[ies] about Gems. In what region the Gem most abounds (or at least is found) as whether in North[ern] or South[ern] climats, in East[ern] or West[ern] Cont[ries]. In what soile the Gem is princip[ally] found, whether in mountains, hils, plains, vallys &c. Near or far from rivers or other water? Whether it commonly ly upon the ground, or beneath the surf[ace] of it, and if und[er] ground, at what depth is to be met with. What are the qualific[atio]ns of the ground that environs it, whether wet or176 dry, barren or fruitful, common or miner[al] Earth; and if mineral, what color, sent, taste, gravity <&c> it has; what menstruums wil or wil not work on it, and whether it will afford any thing by distillation; and if so, what. What are the chief concomitans & circumstances of the gem as `tis 1st found, as whether it be found in Mines or Quarries. Whether the womb (if I may so cal it) that breeds them, will, being robd, produce others and in what time. Whether the Gem be usually found loos & entire, or partly inclosd in stone, or some other mineral, or at least growing thereto (as is usual in Cornish diamons) and which kind of Ston[es] & minerals the Gem is found in, or growing on. Also, whether it grows single or clusterlike: and, whether it differs in the place where `tis dug up from itself, when't has been long in the fre air. Whether there be any differing kinds of the proposed gem, and if any, how What the fig[ure] of the gem naturally is, as whether hexagonal, as Christ[als] and Cornish diamons usually are; or polyedrical, & I have observd divers rubys to be; or of a gibbous form about angles, as many [sic] be seen in some kinds of granats; and whether the determinat fig[ure] belong to the whole gem, as in Rubys newly mentiond, or whether it belong to the prominent parts of it, which has had conveniency to shoot into its natural shape (as I have div[ers] times observed in Chryst[als] or Christallike stones, who near their roots where they grew to the matrix, were of no regular figure, but had one in their body, and at their points. The like I have seen in many Amethists as they were digg'd out of the Rocks. Whether the Gem do always, or almost always, grow pure and distinct in its kind, or do sometimes admit of mixtures and degenerations (as I have seen in a natural stone that was partly diamond and partly ruby; and another that were partly ruby and partly amerand177 or Saphir, and a huge piece of chrystal, which near the apex of its pyramidal part was intensely green like an Emerald, and as the pyramid grew broader & broader, the color green more diluted, till at length it was not discernable. Whether the Gem be naturally of one color, as Emerads, Granats &c. are thought to be, or178 (or least sometimes) of variegated color, as Jaspers, Agats &c. some kind of bloodstons are oft observ'd to be; and whether, in case the whol gem be usualy of 176 followed by `barr' deleted. 177 followed by `and' deleted. 178 altered in composition. 28
`HEADS' AND `INQUIRIES' one color, the color be the sam in all gems of the sam kind, or som of them may be of a color differing from the generality of the rest (as there are white rubeys & white saphirs, and even in diamonds, besides the more usual variety, I have seen an exceptional stone as yellow as a Topaz, and another of a deep reddish color almost like an Estern Ametist. What the hardnes of the Gem examind is, and by what ways its hardnes may be179 estimated, espec[ially] in refer[ence] to other gems. Whether the propos'd gem be a body with equal care divisible every way, as a lump of clay or dough, or have a grain like wood: For I find, that even Diamonds the hardest of known bodies, and wherein one would least exspect fibres may be easily enough split, if it be attempted according to the ducting or course of the fibres; whereas those that graid [?] diamonds assure me, that they cannot /p. 332/ cut them against the grain, and `tis a known thing amongst them, that in other cases, nothing but diamond will penetrate a diamond. Whether the Gem propos'd is capable of being made to afford any odor by the most proper means of manifesting it. Whether the Gem propos'd be fit to produce any peculiar sound in a convenient body. Whether the Gem may be made to strike fire with steel or another gem of the same kind. Whether the Gem may by friction, heat, or otherwise be made to shine in the night. Whether the Gem have an Electrical vertu, and if so, how strong that is. Whether the Gem wil be alter'd as to transparency, color or weight, by lying in water, or other liquors not corrosive, as we see it happens to the Oculus mundi, and probably to some other stones. The Gem being weigh'd in water, what proportion it bears to water of the same bulk. Whether the gem wil suffer any loss of weight by ignition; and if any, what proportion that decrement wil bear to the whole stone, by an ignition of such a determinate time. Whether the Gem by ignition will loose al, or any part of it's color, as it happens to most of precious stones; or wil retain it's color in the fire for a long time; as I have observ'd some kinds of Granats to do after several ignitions; or wil have its color exchang'd, as [I] have observ'd a green stone turned red. Whether the gem be dificult or easy to be ignited, and what color it wil have whilst tis actually so; that we may see how far the fire wil alter the native color of the gem; (as I have with pleasur observ'd, when for curiositys sake I brought some Emerands and other stones ignite). Whether or no the fire (if need be long continued & extended) wil alter the textur of the gem, & if it do, whether it wil calcine or vitrify it; and what degre & continuance of heat is requisite to do either of them; and whether, if the gem vitrify, it wil mix with glas & alter it; & if it calcine, whether the calx have any salt in it, and if it abound therewith; and what proportion in specific gravity the vitrum or the calx beares to the gem before it was expos'd to the fire. 179 accidentally repeated. 29
`HEADS' AND `INQUIRIES' What menstruums will, and what wil not, work upon the gem, either crude or prepard; and what magistery as to figure, tast, color, &c. wil be producd by the coalition of the particles of the stone with those of the menstruum. Whether the color of the Gem proceed from the textur of the whole, or from a separate tincture. Whether the gem be a meer stone, as Christals seem to be, or a more compounded body consisting chiefly of stone, but partly also of some metallin or mineral substance, which by a skilful management may be at least discover'd, if not separated. Whether the propos'd gem may be imploi'd to turn some other matter into the like gem, or whether itself may be turnd into some other kind of Gem by being deprived of its own tincture, endow'd with a new one, or otherwise managed. What are the medical & other vertus of the proposd gem, and how to be best discoverd & examin'd. Whether or no in polishing the Gem care must be had to polish it, as is usual in diamonds, with the grain; or what are the best ways of cutting, polishing, setting, or otherwise advantaging the proposd gem. What are the best ways of imitating or counterfaiting the propos'd gem in order to the discerning betwixt the counterfit & the true. By what marks & ways of trial we may best make choice,180 among the propos'd gems & estimat their goodnes in reference to several purposes, especially those upon whose account they are to be priz'd by the Jeweller, or may be useful to the Physitian. p.

`HEADS' AND `INQUIRIES' r. Topics for the History of Diseases (Sloane MS 2502, fols 1v­2) Prжliminary Topicks or Articles of Inquiry, in order to The History of Diseases. 1 What Climates are more Subject to give the Disease [As we see that the Scurvy is more frequent in the Northern then in the Southern Climates.] 2 What Countrys are only or chiefly upon the account of the soil, the most apt to breed the Disease, whether in the Natives, or in strangers. [As185 Ireland does much dispose men, especially new comers to Fluxes, and Kent to Agues.] 3 What places in regard of the particular situation and other circumstances, do most expose men to the Disease. [As the sea coast usually makes men more obnoxious to the Scurvy then the Inland parts.] 4 What places are free, either totally, or 186 great part, from the Disease, and upon what account they may probably be judg'd to be so. [As China is very seldom infected with the plague, which is also observ'd in divers parts of the East Indies; and in Scotland Agues are very unfrequent & in some part almost unknown.] 5 What places are observ'd to cure, or considerably mitigate the Disease, in Patients that bring it from abroad. [As Scotland is wont easily to cure men of Agues, as the air of Montpellier often does of Coughs and Consumptions.] 6 What Sex is most or less, or not at all subject to the Disease: [As women are more subject to convulsive affections then men, and less subject to the Gout.] 7 What age is most or less, or not at all subject to the Disease; [As old men are more subject to the Gout, and the stone of the Kidneys, midle-agd men to the Phthisis or consumption, children are most to the stone in the bladder, but not at all to the Gout.] 8 What complexions, or constitutions are most or least subject to the Disease. [As sanguine Persons are most subject to bleedings, Phegmatick to Rheums, & Coughs; Cholerick to Feavors, and sharp Fluxes, Melancholy187 Persons to affections of the spleen to Hypocondricall affections, particularly Quartane Agues, &c] 9 What course of life dos most dispose or indispose men to the Disease. [As Guilders & Plumbers are often subject to Palsies & affections of the nerves; the makers of Ceruss to cholicks; sedentary men are far more subject to the Gout, then labouring men, or those that doe much exercise.] /fol. 2/ 10 What kind of diet do's most or least, dispose men to the Disease or releive them in it. [As Salt Fish & powdered Biefe do's to the scurvy, which Oranges, and divers green herbs, besides scurvy-grass, do often cure seamen of; or at least much releive them. Thus in the Alps, and some of the Spanish Mountains, the Inhabitants are subject to great & unsightly tumors in their necks by drinking of snow water.] 11 What influence the season of the Year may have upon the Disease, either to breed, encrease, change, or cure it. [As quartans seldom begin, but in the Autumn, or winter, and frequently goe off, or turne to tertians in the springe; or in the begining of Summer. And Autumnall tertians doe oftentimes when the cold comes on, degenerate into Quartanes. And the Plague that rages in the summer, does often 185 preceded by `I' deleted in Locke's copy. 186 inserted in pencil. 187 Locke's copy has `melancholick'. 33

As, what Age, Sex, Climate, Soile, Complexion, Diet, course of Life &c. The Disease is more or less fatall, mischievous, or benigne. As `tis observ'd that the small pox is extreamly mortall in China, even slight188 wounds in the head, are far more dangerous in Italy, then in England, or France, and so small hurts of the Leggs about Geneva, and Lusty labouring men such as Diggers & Hedgers rarely recover of Pleurisys. What Constitutions either single or successive of the seasons of the year. What great alteration of the Air, by great & lasting Raines, Winds, Droughts, Earthquakes, fiery Eruptions, great spots in the sun, vanishing, or reappearing Starres, Comets &c. did precede189 or accompany the Disease; also whether it be a new Disease, or have been from the begining of the World, and even in this part of it, whether in case it be new `twas introduc'd & propagated by, or without manifest Contagion, whether it's malignity encreases or lessens, by progress of Time, as many Physitians observe the symptoms of the Lues Venerea, to have been for some considerable time far milder then when the Disease began first to appear in Europe. s.
