Questiones quædam Philosophc|i|æ

Off ye first mater

Whither it be mathematicall points: or Mathematicall points & parts: or a simple entity before division indistinct: or individualls i.e. Attomes{.}

|1| Not of Mathematicall points since wt wants dimentions {illeg}|ca|nnot constitute a body in theire conjunction b{illeg}|e|cause they will sinke into ye same point. An infinite number of mathematicall points sin{illeg}|k| into one being a{illeg}|d|ded together & yt being still a mathematicall point is indivisible but a body is di{illeg}|v|isible. In fine a Mathematicall point is Nothing, since it is but an immaginary entity. &

Not of parts & Math: points; for such a point is either something or nothing. if something tis a t & so added betweene 2 ts will make a line of 3 ts. if nothing, then added betwixt two parts there is still nothing betwixt ye 2 ts & consequently ye line consists of nothing still but 2 ts. &

Not of simple entity before division indistinct. for this must be an union of ye parts into wch a body is divib|s|ible since those parts may againe bee united & become one body as they were before \at the creation./ Now ye nature of union (being but a modall ens) is to depend on its pts (wch are absolute entities) therefore it cannot be ye terme of creation, or first matter for tis a contradiction to say ye first matter depends on some other subject (except God) since yt implie|y|s some former matter on wch it must depende.

<88v>

|2| homogeneis The first matter must be homogeneous & so either all hard or soft or of a midle temper if hard yn all ye ts into wch it is divisible will be hard & of ye same constitution will all ye ts be into wch it is divisible. so yt where there is plenitude of mater it will be of ye same temper ye first was & there will be no change in nature unles you will allow it either to arise from vacuities interspersed or from ye severall proportions yt quantity hath to its substance: Matter acquiring a harder nature by less quantity & a softer by more. likewise there will be no other way for rarefaction & {illeg} condensation.

If ye first way then ye body will be no such pcontinuū as to be wthout distinct \parts/ since it will be every where divided by interspersed inanitys

The latter will be in its due place be proved impossible

|3| Those things wch can exist being actually {seperate} are really distinct, but such are ye parts of mater.

|4| Suppose ye first matter one uniforme mass wthout ts how should that body be divided int{illeg}|o| parts as we se now it is wthout admission of a vacuum. Suppose it be divided into two what will be betweene those two parts not body since it is all in ye {illeg}|t|wo halfes. But if it be said yt it was{illeg} first divided into smaller parts wee ask how came it so wthout less parts yn those into wch it was \at first/ divided or els vacuum to succed in theire rome as they came a peices. {illeg} Suppose ye would first matter were \divided/ as small as sand yn divide one of those sands a third sand cannot succed twixt 'em before they be at some distance unles they be at some dis there might be some smaler matter to run in & keepe out vacuum but to affirme this is to say ye first matter had very little parts be in it before it was divided. But againe |if| \now matter is divided/ two {illeg} parts of matter of ye least size. were seperateing & distant one from another ye space & halfe

<89r>

Of Attomes.

It remaines therefore yt ye first matter must be attoms. And yt Matter may be so small as to be indiscerpible the excellent Dr Mo{illeg}|or|e in his booke of ye soules imortality hath pr{illeg}|o|ved beyond all controversie yet I shall use one argument to shew yt it cannot be divisible in infinitum & yt is this: Nothing can be divided into infinite /more\ parts yt|n| it can possibly be constituted of. But matter (i.e. finite) cannot be constituted of infinite parts. The Major is true for looke into how many parts ye a thing is divided those parts added agane make yt same whole th{illeg}|at| they were before; & so if any finite quantity were divided into infinite parts (& certainely it may if it be so far divisible) those infinite parts added would make ye same finite quantity they were before wch is again ye Minor; & It is plaine from hence yt an infinite number of extendid parts \& ye least parts of quantity must be extended/ make a thing infinitely extended & all ye parts yt qua this you cannot \be/ denyed if I can prove yt things infinitely extended have fine parts Now vacuum is infinitely extended & so \may/ matter be fansied to be. but if ye world were removed & vacuum came into ye roome of it yt very vacuum would not be infinite we can conceive of interspersed vacuities in \amongst/ matter but they are not infinite (though an infinite number of ym would be so) we see ye parts of matter are finite. & an infinite number of finite unites cannot be finite. To helpe yt conception of |ye| nature of these leasts, how they are indivisible how extended of wt figure &c I shall all along draw a similitude from numbers, comparing ciphers \Math: points/ to ciphers, indivisible extension, to unites: divisibility, or compound quantity, to number: i.e. a multitude of attomes, to a multitude of unites. Suppose yn a number of Mathematicall points were indued wth such a power as yt they could not touch nor be in one place (for if they touch they will touch all over, & bee in one place) Then ad thees as close in a line as they can stand together every point added must make some extension to ye lenght because it cannot sinke into ye formers place or touch it so here will be a line wch hath partes extra partes; {illeg} another of these points cannot bee added into ye midst of this line, for yt implys yt ye former points did not lie so close but yt they might lye closer. The distan\ce/ yn twixt each point is ye least yt can be & so little may an attome be & no lesse: now yt this distance is {illeg} indivisible (& therefore ye matter conteined in it) is thus made plaine: Wherever

halfe theire diameter (they will not then touch, for yn their semidiameter will bee but as a \Math:/ point & theire diameter a two Mathematicall points together i.e. as nothing (for 2 nothings put together make a third nothing) & so yeleast parts of matter Mathematicall points wch is absurd) Vacuum will yn come betwixt if nothing else can, & no matter will come betwixt since ye diameter of ye least particle will be bee {sic} as big againe as yt space. If it be said yt matter {illeg} may move {ye} \over so little/ space in an instant & other matter succeed in an instant & so there needes no vacuum) I answer it may as well be moved throu\gh/ ye Vniverse in an instant for instantaneous motion is infinitely swift & will carry ye thing in wch it is as soon through an infinite space in an instant as well as though a finite space or ye breadth of an attome & I cannot conceive how so violent a motion should be stopt wthout some violent effect though in so little an agent what is saide of so little bodys may be said of greater As thus suppose two globes were to be seperated come together they must pas through all ye intermediate degrees of distan{illeg}ce before they can be joyned suppose they then be distant but halfe ye breadth of ye least partic{illeg}|l|e of matter there can be no matter betwixt ym since all matter is too big to interpose it sefe {sic}. Neither can ye two globes touch for yt implyes yt semidiameter of ye least attome hath no breadth but had it not breadth ye diameter could have none & so ye least particles of matter would be Mathematicall points. therefore A vacuum must interpose. But you may say {illeg} |Vnles yu say those attomes are as far divided as they ar divisible {illeg}| |yt| there are least parts of matter was is proved in ye chapter of attomes.

* i.e. so little yt theire can \not/ be a place too little for ym to creepe into & yn you will grant wt I pleade for i.e. indivisible particles. & you must grant too yt Attom{es} were either created so or divided by meanes of a Vacuū

<90r>

Of Quantity

As a finite lines added in an infinite numbers to finite lines, make an infinite line: so points added twixt points infinitely, are equivalent to a finite line.

All superficies beare the same proportion to a line yet one superficies may bee greater yn another (yesame may be said of bodys in respect of surfaces) wch happens by reason yt a surface is infinitly in respect of a line, soe though \all/ infinite extensions beare yesame proportion to a finite one yet one infinite extension may be greate\r/ \yn another/ soe one angle of contact may exceed another, yet they are all equal when compared to a rectilinear angle viz wch is infinitely greater Thus {illeg} 20 {illeg} is double to 10 & 01 is double to 02 {illeg}, for multiply ye \2/ first & divide ye 2ds by 0, & there results 21 : 11 & 11 : 12. yet if 20 & 10 have respect to 1 they beare ye same relation to it yt is 1 : 20 :: 1 : 10. & ought therefore to bee considered equall in respect of an unite.

The angle of contact is to another angle, as a point to a line, for ye crookednes in one circle amounts to 4 right angles & yt crookedness may bee conceived to consist of an infinite number of angles of contact, as a line doth of infinite points.

Conjunction of bodys.

Whither it be from ye close {conjunction} /crouding\ of all ye matter in ye world affirmatur. For ye aire (though its pressure bee but little in respect of yt, performed by ye purer matter of ye vortex (twixt & us) receding from ye center) & by its pressure to ye center & consequently crouding {illeg} all thing close together betwixt wch there is not aire to keepe y asunder it maketh y stick together, as ye 2 pollished sides of 2 marbles \ye {Lots} of water/ &c but this juncture caot be very firme by reason yt ye pressure of ye aire is not verry strong as appeares by ye experiments of E Boyle. but ye pressure of all ye matter \made by reason of its indevor from ./ twixt o|| & us being farr greater (& it may be some other power by wch matter is kept close together&c) when 2 or 3 or more littell bodys once touch so as to admitt noe other matter betwixt them they must be held very fa{illeg}|st| together al ye matter about y pressing ym together but nothing striving to te ym. And when 2 of ye least particles touch wth very broad sides meete whos sides wth wch they touch one another are pretty broade & fitted to one anot touch close every where, those two may move together as one body & so may increase by haveing others joyned to ym in ye same manner. but if ye circumstant particles chanch to be held of from pressing ym {illeg} together as by some accident as those about (a) or be variously pressed as at (b) by ye bodys c & d they may be againe severed. yet in more compound body's there is no danger as for the least particles are so wedged togr: yt neither of these two chanches could undo ym as for ye firs {sic} it cannot to a whole body b{illeg}ut onely in some litte{illeg}|ll| te of it as some attome of a mans hand may chanch not to be touched by ye water into wch hee puts it. But this cannot happ to his <91r> whole hand.

Of Motion

That it may be knowne how motion is swifter or slower consider i That there is a least distance, a least progression in motion & a least degree of time. as lay two globes together yt so close yt they cannot come any nigher wth out touching yt is ye least distance, let ym be moved together yt is ye least degree of motion & tis performed in ye least part of time. There are so many parts in a line as there can stand Mathematicall points in a row wth out touching (i.e. falling into) one another in it & soe many degrees of motion along yt time. \as there can be stops & stays./ & there are soe many least parts of time in an hower as there can be Τὸ νὺν᾽ς. This oposition is proved as I proved a least part in Matter. 2 These leasts have no parts for yt implys yt they are yet divisible. |nei|the|r| prius nor posterius 1 not \least/ distance since it is passed over in an indivisible part of time & ther cannot be a different time ascribed to ye entrance of a thing into yt part of space & ye leaving of it. 2 not ye least degree of motion because too yt is performed in an indivisible te of time & is no sooner begun yn done 3 {illeg}|n|ot ye least moment of time because first & last imply severall parts of time. 3 The least degree of motion is equal to ye least degree of space distance & time |1| distance & not to more: because a thing moves in passing over but one of y. Nor to less, because ye least motion is over some distance. 2 Tis æquall to ye least moment in time, not to more, because in each degree of time wherein a thing moves there will be motion or else in all those degrees put together there will be none: not to lesse becaus no motion is done in an instant or intervall of time. But againe should two parts in motiō be but equall to one in space or time &c contra: yt one would be liable to have a prius accor{ding} to ye firt of ye two parts a midle according to ye {illeg}

Of Gravity & Levity

The matter causing gravity must pass through all ye pores of a body. it must ascend againe. |i| for else ye bowells of ye earth must have had large cavitys & inantys to conteine it in, \2/ or else ye matter must swell it. 3 ye matter yt hath so forcibly borne {down} ye earth & all other bodys to for ye center (unles you will have it growne to as gross a consistance as ye Earth is, & hardly yn) cannot if added to ye Earth gether be of a bulke so little as ye earth, for it must descend exceding fast & swift as appeares by ye falling of bodys, & exceeding weighty press\ure/ to ye Earth. It must ascend in another forme yn it descendeth or else it would have a like force to beare bodys {illeg} yt it hath to press ym downe & so there would bee no gravity It must ascend in a grosser consistence yn it descends because it may be slower & not strike boddys with g|s|o greate a force to impell ym upward 2 yt it may onely force ye outside of a body & not sinke into every pore & yn its densness will little availe it because it will yeild from ye superficies of a body wth ease to run in an easier channell as though it never strove against ym. if it should ascend thinner it can have onely this advantage yt it would not hit bodys wth so weighty a force but yn it would hit more ts of ye body & would have more ts to hit wth & hit wth a swifter /smarter\ force: & so cause ascension wth more force yn ye others could do descension. Wee know no body that {} not sinke into ye pores of bodys finer yn aire & it will sink into most if it be forcibly crouded in ye stream descending will lay some hould on ye streame ascending & so press it closer & make it denser & therefore twill rise ye slower. ye stream\e/ descending will grow thicker as it comes nigher to ye earth but will not loose its swiftnesse untill it find a much opposition as it hath helpe from ye following flood behind it. but when ye streames meete on all sides in ye midst of ye Earth they must needs be coarcted into a narrow roome & closely press together & find very much opposition one from another so as either to turne back ye same way yt they came or croud through one[2]

Of Heate & Cold.

Apples, Eggs, Cheeses, Men &c: frozen are {illeg} {illeg} vitiated by freezing but not soe much when thawed by water or snow as by fire. Frost will breake stones, crack trees, make ye Humor chrystall looke white.

A man cannot feele where hee is frozen & though frozen all over feeles onely a prickling in his recovery, hee may bee recovered being dipped in water or rubbed over wth snow, but not by a {illeg} Stove. Nay any frozen part is lost wch is thawed in a Stove. & ye fier pains us in warming or cold fingers. Frozen meate layd to thaw & roast by ye fire will bee raw in ye midst after many Howers.

Though frost change & destroy bodys (espetialy in ye thawing) yet cold preserves them.

T|I|ce (to wch noe fresh aire in ye Frezing could come ye botome of ye water being first frozen &c) is full of bubbles {like} \great as/ sands, shott, & pease, wch bubbles are fewer & lesse if ye water bee first purged of aire by ye receiver. And those bubbes in thawing shrink againe perhaps into as little rome as at first.

Cold shrinkes liquors, Oyle shrinke in frezing, water scarce shrinkes before frezing, but swells before & in frezing, & Ice is about one ninth or tenth parte greater yn water

Of Reflection Refraction & Vndulation

Of violent Motion

Violent motion is made \continued/ either by ye aire or by motion or force imprest. or by the naturall gravity in ye body moved. Not by ye aire since ye aire {illeg} crowds more uppon ye thing projected before, yn behind, as must therefore rather hinder it but if ye aire helps it why doth ye thing at {last} fall for you may Figure observe in water yt a thing moved in it doth carry \ye/ same water behind it along wth it as in a cone or at least Figure ye water is moved from behind it wth but a small force as you may observe by ye motes in ye water supose (a) to be ye boddy moved: (b. d. e. f) to be ye water moving behind (a) to give it place. (r) ye water behind (a) following it & going along wth it. The{n} if ye water at (f) ran so violently against ye backsid of (a) it would beate away ye water at (r) with violence but yt water is moved very slowly from behind a. as you if it be moved away: as you may perceive by ye motes in ye water. againe this wil the like must hapen in aire if you say no I answer must yn move (a) forwards in water. So if hot leade drop into water yt te wch is behind {illeg} will be pointed ye fore te round wch would be otherwise if ye aire pressed as much on it before/hind\ as behindfore. thirdly how can ye aire continue ye motion of a globe on it {sic} axis. Fourthly <98v> in ye former figure ye aire is supposed to have ye same propensity to motion wch ye ball (a) is supposed to have that is will move no longer yn it is propelled on. yn I say ye water at (r) cannot move ye ball unles ye ball do at ye same time move (b) yt (b) may (g) & (h) & (g) may move (d) & (d) move (i) & (i) move (f) & f move r & force it to rush uppon ye ball & consequently at ye same instant (r) must ye ball, & ye ball move (r) wch cannot be. But suppose ye aire & ye ball were detained from motion by some outward agent, & yet kept ye same respect to one-another in situation as they did in the{illeg}|i|re flight: then as soon as they were both let loose againe ye aire would have as much power to move ye ball as it had when they were in theire former flight: If it be answered yt ye aire will be more compressed at (f) yn at ({illeg}|b|) & consequently when let loose againe it will dilate it self & so begin a new motion. I answer how comes ye aire to be more crouded behind ye ball then before since since {sic} (a) will communicate as much force on (b) as it receives from r & ye fore te of ye aire will croud no more on ye latter parts yn ye ball will croud on if it. Againe whence is it yt a {illeg} peice of leade will move faster then a peice o farther & wth more force yn a peice of wood of ye same bignesse since ye aire will have ye same influence on both.

Why refraction is less in hot water yn cold

|Whither is salt or fresh water easlier {moved} & more pellucid. refracts more & easlier frozen.|

Of Water |& Salt|

Whither fresh water consist of long bending attomes \parts/ & salt of stiffe & long ones. ye first is false because it could never bee frozen. 2 they would twist & about one another so as they would not be fluid but onely soft. 3 they would ly too close together to admit light through them for being pliable they would fill up every corner & hence they would bee exceeding heavy. 4 they would not refract light so well, for beeing they would bee soft & so not firmely resist ye {illeg} pure matter as Glass doth & Cartes would have yt matter to passe swiftlier where it findes strongest resistance & refraction to be from hence yt ye matter passeth swiftliest wch therefore should bee in water. 6|5| twould scarce seperate salt so soone. & when if it seperate it by laping about it yn when it hath seperated as much as it can of one kind of Salt it could seperate no more of another wch is false 6 The aire being a stubborne body (because of branchy parts) would instantly quell there circular motion when they are rarefied. |Why water is clearer yn vapors.|

Whither burning waters & hot spirits be of small spericall {sic} &{illeg} ovall figud parts & have many such globulis as fire is of they are 1 because such are f easliest seperated in distilllations {sic} 2 because they are easliest agitated & so heate & enliven men 3 they must have many small & sollid attomes in ym because so easly fired.

Why doth hot water first contract it selfe (viz in cooleing) & yn dilate it selfe before & as it freezeth.

Why doth salt & snow freese other water. & why is heated water sooner frozen yn other raw water.

Whither be ther more vapors when ye aire is clearest.

How salt hinders corruption. {illeg}but fresh water helpes it.

Of light |see pag 82|

Why light passeth easlier through white yn black paper. & yet more efficaciously reflected from it.

How light is conveyed from ye Sun or fire wthout stops.

Light is easlier admitted into black yn reflected from it, for hold a paper twixt you & light wth a black spot in it & it is blacker when towards you, yn when to ye light.

Light caot be by pressiō {sic} for yn wee should see in ye night {sic} wel or better yn in ye day we should se a bright light about us becaus we are pressed downewards wee should se when we shut or eyes because or eye lids press ym or when we put or hands on or eys. The sun {illeg} would be long so long as we looke at ye same thing yt pression is ye same nay far greater. ther could be no refraction since matter ye same matter cannot presse 2 ways, ye * sun could not be quite eclipsed ye M\o/one & planetts would shine like sunns. A man goeing or running, would see in ye night. When a fire or candle is extinguish we lookeing another way should see a light. The whole East would shine in ye day time & ye west in ye ni{illeg}|ght| by reason of ye flood wch carrys or. Vortex a light would shine from ye Earth since ye subtill matter flows /tends\ from ye center. a * little body interposed could not hinder us from seing pression could not render shapes so distinct. There is ye greatest pression on {illeg} yt side of ye earth from ye or else it would not move about \in equilibrio/ but from ye , therefore ye nights should be lighest {sic}.

Of Sensation

The senses of divers men are diversly affected by ye same objects according to ye diversity of theire constitution To them of Java pepper is cold.

If ye orifice of ye stomach be wounded it sooner dispatches a mā yn if ye head: ye former having greate sympathy wth ye heart deads it & stops it motion & so sence ceaseth: ye latter though it take away sence yet ye hearts motion is not impeded thereby.

The Common sensorium is either 1 ye Whole body 2 ye Orifice of ye Stomack 3 ye heart 4 ye brain 5 ye membranes 6 ye septum lucidum 7 Some very small and perfectly sollid particle in ye body 8 ye Conarion 9 ye Concurse of nerves about ye 4th ventrickle of ye braine. 10 The animall spirits in yt 4th ventricle.

A ligature being tied sence & motion will be twixt ye ligature & ye head but not downwards. A frogs brain being peirced it looseth both sence & motion but it will leape & have its sence though its bowells bee taken out.

Of Vision

There is required some permanency in ye object to perfect vison thus a coale whirled round is not like a coale but fiery circle or who can se a bullet pass by him. yet if ye eye keep motion {illeg} wth ye thing moved it sees it right One eye shutting or being perst ye pupill of ye other open both ye eyes being opened together, dilate, & cotract {sic}, & dilate. Vppon passion these spirits ebb & flow. Dymnesse may come from ye deficiency of these spirits, & ye Optick nerve ob\structed/

Rays fro{illeg}m ye same point in an object strikeing upon {illeg} several respective places in either /both ye\ eyes do seeme make ye object seeme two as when an aye is deprest viz: yn theire two axes respect not ye same point, in yt object. B{illeg} Things of ye darker color are easliest burned i.e. have loosest parts. A mans Eye struck sparkeleth.

The Eys being distorted a man may see ye same parte of ye same object, in two divers places \wth both eys/ at once or successively wth one eye after another, & also hee may see two divers objects wth one eye after another but in ye same place successively but not at once (wthout varying the posture of his eys or of ye object, but onely by covering |ye| one eye first & then ye {illeg} the other, or by being intent wth one eye first & then wth the other. wch is an argument either yt ye image in ye braine is painted on a superficies, or else yt ye Optick nerves at their meeting before they enter the braine doe sort their capilamenta & unite|i|ng there each capl|i|lamentum of the one eye to its fellow capilamentum of ye other eye. Soe yn|| wn ye eyes conspire not towards ye same object but have divers pictures painted upon ye same capila correspondent capillamenta ye stronger picture at their meeting of those capillamen{ta} drownes ye weaker &c:

Quære: why doth ye forcible turning of ye eye one way wth ye finger make ye object seeme to move the other way but not ye voluntary turning of it.

<105v>

Of Colours.

That darke colours seeme further of yn light ones may be from hence bee yt they beames loose little of theire force in reflecting from a white body because they are powerfully resisted thereby but a darke body by reason of ye loosenes of its parts give some admission to ye light & reflects it but weakly & so ye reflection from whitenes will be sooner at ye eye. or else because ye whit sends beams wth more force to ye eye & givs it a feircer knock.

Coulors arise either from shaddows intermixed wth light, or or {sic} stronger & weaker reflection or [arts of ye body mixed wth & carried away by light.

From some of these ariseth splendor & dullnesse

A shining colour though black reflecteth an Objects {illeg} rayes perfecter yn dull white one as black horne black pollished leather &c better yn white paper. & contrarywise. But pollished black shineth best

A window lying open to ye south will bee tincted wth ye colour of ye curtane. A paper written on put twixt ye eye & ye light ye letters towars|d||s| ye light looke dim ye light being refracted in ye paper after its' past ye inke: but ye letters on this side looke perfect ye light comeing streight to ye eye wthout any refraction

Why are coles black and ashes white.

No colour will arise out of ye mixture of pure black & white for yn pictures drawne wth inke would be coloured or printed would seeme coloured \at a distance/ & ye verges of shadows would be coloured. as therefore & lamb black & spanish whiteing would produce colours whence they cannot arise from more or lesse reflection of light or shadows mixed wth light.

Of Sounds

A man may heare ye beatings of his owne pulse.

In every sound ye eight above it but not below it seemes to bee heard. (for there being \is/ some more subtile, some more grosse matter in ye aire, & ye subtilest matter is prone to quickest vibrations, though ye motion of both proceede from ye same cause, as ye vibration of {illeg} a string or pipe \thus twiggs vibrate ofter yn branches/. Also these motions doe least check one ye other & are most congruous to ye string or pipes motion when ye ones vibrations are double in number to ye others. Hence a sound & its eight are never seperate. The greatest & grossest t of ye aire matter in ye aire will \doth/ comply wth ye strings motion for were it slower it could not give way to ye motion of ye string & it will scarce bee quicker by reason of its tenacious nature for one string struck \by ye mediation of ye air/ moves an unison string of another instrument better yn yt wch is an Eight above or below it & ye {illeg} string is easliest moved by ye air when its {illeg} motion can be most comformable to ye \motion of ye/ greatest te of ye aire. Nor can any considerable quantity of matter give move slower yn ye string because it gives way to ye strings \motion/ Hence ye & were there, yet it {sic} mot{illeg}|ion| \being/ 4 times slower yn |yt| \of/ ye subtilest matter can scarce bee perceptible. Hence each sound hath its concomitant 8th, & haps {illeg} 15th & 22th to a good eare, above but not below it. Hence 8ths seeme to bee unisons. And And violenter breathing raiseth ye sound & sight or 15th not a 12th, or but seldom to a twelft.

Quære, In wt proportion ye sound decreaseth in its progresse from ye fountaine. viz: If ye sound bee (a) at ye distance (b) it shall be (a b bx x) at ye distance x.

Why doth ye sound of a Bell quaver or shake like a mans voyce? Because ye Bell vibrates sometimes directly somtimes obliquly towars a man

Dr Mores immort:

Things out of mind are remembred sometimes by meeting wth other things of like nature: as dreames never thought uppon in yt morning at ye time of awakeing are remembred by some actions of ye like nature met wthall in ye day time.

Forgetfullnesse ariseth sometimes out of ye want of thinking of things. Things seene & words heard at ye same{illeg} distance are distinctly remembred. So are distance & widenes or extension & bignesse. So are things wch enter not ye sences as meditations, thoughts, dreames, & yt a man hath remembred.

Meditations reminde a man of actions, & actions of meditatio. Colours, actions, sounds loud softly, high & low, Time as yt 2 things were done together or so long after one another reconing how long since such a thing done by counting ye time from one action to another untill ye præsent time.

The Saltpeeter opens ye poores of ye mettall to let ye filth evaporate & ye Tartar helpeth to carry it away. If this mettall must bee cast smo{oth} line the sand mold wth the smoake of a linke.

|1| That there may be motion in vacuo let us suppose (a b) to be a body as a peice of earth \Aire/ (c. d. e.) to be three globes, (f g h i) & all ye space about ye globes & that earth \aire/ to be inane now in ye chapter de vacuo w{illeg}ee have shewed that those Figure three globes would be really seperate & not touch one another. you will grant yt halfe ye globes are in places & halfe in vacuo & consequently may move, suppose yn yt halfe of (r) in ye earth \aire/ move towards (d) we aske whither that part in vacuo would move along wth it or stay behind & \be/ seperated frome it if ye first we have or desire if ye last wee ask what should seperate it from it not ye vacuum since yt is accounted nothing. but you may say yt it is not truly motion for ye upper te of r to be carried to (d) we answer yt where there is action (for such is ye passing of (r) to (d)|)| & where there are new respects acquired to other \ye same/ bodys there must be motion, but ye upper part of |(r)| hath neither ye same respect to ye aire wch nor to (d) wch it had before it began to pass towards d. but this but to quarrell wth ye termes If this {motion} \going of r to d/ be not motion I aske what it is. but this is onely to strive about termes & if it please you not to call it motion cal <114r> it what you will but it is yt which we aimed to prove & there is but this difference twixt it & motion in pleno. yt ye one is environed with such bodys {illeg} mater as is impenitrable & consequently yt mater must be crouded out of ye move|i|ng bodys way before or rather at ye same time yt ye body moves, it must needs impede ye motion by \to/ be continually thrusting against & resisted by ye body before it: but in vacuo it meetes wth nothing \impenitrable/ to stay it & {contein by then} tis true God is as far as vacuum extends but he being a spirit & penetrating all matter can be no obstacle to ye motiō of matter noe more yn if nothing were in its way Let mee aske why one should be motion more yn another since a vacuum ca in pleno motion is so stopped by one body rubbing uppon another & in vacuum it hath its liberty can ye same thing (viz \a/ being invironed wth bodys) at ye same time {illeg} give a being to motion & yet destroy it, wherefore to be in pleno cannot be essentiall to moc|t|ion. & if it were things would be more properly sade to move where there is most body or they find most resistance to theire motion & so more properly in water yn in aire &c. But it \is/ objected by Aristotle yt a Vacuum is uniforme & every where alike & a body hath ye same respects to a vacuum in all places alike but there is no motion with some mutation of circumstances {illeg}|An|d so in Vacuo no motion I answer as to or senses ye aire is unifor And we judge a thing to be moved {illeg} \when/ we se it come nigher or d goe farther from some thing wch or senses can perceive & so we judge not a thing to be moved in respect of ye aire but of ye earth or some thing

The 1st day ye tayle was avers from exactly its \tayle/ reached beyond |  below ye {illeg} <115r> lower wheeles in ye \Great/ Beares belly & was in \a/ {illeg}manner ∥ to ym. But it declined a little \afterwards/ from toward \upwards/ Sometimes ye d|t|ayle declines from 20 or 30 degres east or westward. The tayle of this last Comet was sometimes 25d in length. The beard of it was so raire as yt starrs might be seene through it.

Therefore ye longitude of it was {illeg} 48d 4'. its latitude 22d, 3', 44". At about 9h 24' at night

December 24th it appeared as on ye day before, being distant from Rigel 28d, 24'; from Aldeb: 24d 12{'} Sirius being 20d high yt is it was 10h 28' |  26' at night. whence its longitude was 44d 7' its latitude Northward \southward/ 18d 23'.

The length of its tayle was about 11d being extended towards Aldeboran or a little below it parallell to ye Ecliptick. The tayle now perfectly manifested it selfe on yt west east side & ye began to discover it selfe, ye cloude being now dissipated.

Division can be made a Mathematicall point or superficies may be betwixt ye parts divided /divisible\ but a point cannot be put or conceived in this little space to divide it. Add yn a \naked/ point {illeg} to any space in thi|e| line I ask {illeg} whither it bee in ye space wthout touching ye \any of ye/ other pointes yt make{s} ye line or not. if you say tis yn I answer yt a point wch would have resisted touching might have as well beene added before wthout an absurdity. If you say yn yt it must touch one of ye other points yt make ye line. I say yn yt that point is in ye same place wth ye point wch it touches, & so not in ye space wch you would have divided. how can yn yt space be divided into wch a mathematicall point cannot enter to seperate its ts? & so how can an attom be divided wch is no larger yn to fill up yt space. It {sic} like manner (yt it may appeare \of/ how nigh kindred number & {illeg} Extension in matter is, in soe much yt nothing can be supposed of one, but may be so of ye other) suppose there were ciphers of such a nature & quality yt they will resist being ye same. {illeg}|L|ay ym together they will not turne all to one nothing since theire qualities require some distance or difference amongst ym betwixt each one of ym let ye first be a bare cipher, ad another will be different from yt & it can differ no less yn an unite ye third yn must differ from both of{sic} y & yt can be no lesse yn 2 units &c Every cipher thus qualified being different or distant from all ye former by ye quantitie of an unite if yn 11 such ciphers added make {illeg} ye difference of 10 unites {illeg}|to| make ye number of 10 see yn if you can ad another cipher thus qualified into ye midst of ym as betweene 5 & 6 ye cipher will be neithr 5 nor 6 for yn it would bee added too ym not betweene ym & so be ye same wth yt to wch it is added wch is against its nature. There is {illeg} no difference betweene {illeg} 5 & 6 where by it may not be ye same wth some other number and so therefore it cannot bee admitted into ye number 10 so {illeg} a naked cipher to ye number there is nothing twixt 5 & 6 (ye difference or distance of ye numbers /or space betwene ym\) in wch it can be therefore it must be either add to 5 or 6 / ye joyn <119v> (as may say of those \ye / numbred unites.) By yt way you may note yt tis not ciphers haveing power to keepe seperated or different from yt sort of being to wch it is added but ye actuall resistance of being one wth ym & therefore ye first ciper {sic} of ye multitude thus qualified will be still a plaine cipher because there is no former cipher whose nature it wth wch it should be one wth but yt 2d ciper refusing to be what ye first is makes ye unite or indivisible basis of number. So a Math: point is not extended by haveing power to resist conjunction wth another unles theire be another point wth wch it refuseth to be seperated, & yn there is distance betwixt ym two though indivisible & ye least yt can be yet ye basis of all other extensios {sic} & ye mould of attoms. I would not be mistaken as if I thought a point or Cipher (were|hich| are nothings) were capable of powers or qualities but b{illeg}|ec|ause I thought it a supposition easie to coceive of & fit for ye purpose I ventred upon it & though it be impossible yt ye thing should be so yet it is not so to conceive it: nay if attomes be so small tis necessary to conceive they are termined \& touch others/ by Math: points & superficies tho at so small a distance as is described here, though held asundr by ye attome & no power of theire owne.

Object: ye least extension is infinitely {illeg} larger yn a point & theirefore can conteine it & be divided by it

Resp: I confess it is so & therefore can conteine an infinite number of points but they must be all in ye borders or extreames \sides & outward superficies of it/ & yt can not point \make/ out a place for division: for ye least distance in yt whole attome is from one {par} extream to another it hath no inside, no midst, nor center but is it selfe ye but is it selfe all center inside & midst to ye invironing superficies & all it can do is to keep those points on eitherside it from touching You cannot put a point wthin it becaus it hath no inside set a point uppon it & yn it touches but its superficies {How} can a point yn be in ye Attom & distant from one extream & yet not in ye other. put a point to one extreame of it & lett it move into ye place where you conceive it might be wthout touching either side towards ye <120r> other extreame yn it is no sooner from one extreame but it is at ye other (because it is no soner out of one \extreame of a/ place (for it can \not/ be in a place) but it is in another & ye 2 extreames of it are ye termini of ye nighest & joyning parts of place) can it yn be where tis impossible for it to rest from motion nay if it should get from one extreame & not reach ye other yt would not be motion because ye least motion is over ye least distance & ye least distance is from one side to anothr in ye Attome. ye whole attom is all in ye same place

What ever can be objected against indefinite divisibility {illeg} in bodys may also bee objected against ye same in quantity & number. but if ye fraction 103 bee reduced to decimals it will be 3,33333333 &c infinitely. & what doth {illeg} every figure signifie but a te of ye fraction 103 wch therefore is divisible into infinite ts

2dly If adbc be shaddow & cdsr white then ye slowly moved rays \coming from cdqp/ will be refracted as if they had come from eodc soe yt ye slowly moved \rays/ being seperated from ye swift ones \by refraction,/ there {illeg} ariset 2 colours kinds of colours viz: from ye slow ones blew, sky colour, & purples. from ye swift ones red, yellow            & from them wch are neither moved very swift nor slow ariseth greene but from ye slow & swiftly moved rays mingled ariseth white grey & black. whence it is yt cdqp will not bee /appeare\ red unless qsrp be darke because as many slow rays as come from cdqp & are refracted as if they came from eodc, soe many slow rays come from qsrp & are refracted as if they came from dqpc unless unlesse {sic} qsrp be darker yn dqpc

But if this pore were something bigger so as to let ye slowly moved particles ○s passe through wth losse of most or all theire motion, but letting ye swift ones scape freelier yn ye colour will be red, yellow &c: as in glasse it <123v> may be whose poores are full of smaller particles of |ye | tincture y those \pores/ of blew glasse are,

8 Though 2 rays be equally swift yet if one ray be lesse yn ye other that ray shall have \so much {illeg} lesse/ effect on ye sensorium as it has lesse motion yn ye other &c.

Whence supposeing yt there are {loos} particles in ye pores of a body {illeg} as {illeg} as \bearing proportion to/ ye greater rays, as 9 : 12: & ye less globulus is in proportion to ye greater as 2 : 9. ye greater globulus by impinging on such a particle will loose a 67th tes of its motion ye less glob: will loose 27 parts of its motion & ye remaining motion of ye glob: will have almost such a proportion to one another as {illeg} in quantity have. viz. 57 : 17 :: 9: 145 wch is almost 2 {ye less} glob. & such a body may {proove blew} & {purple}

The colours I suppose next ye flameing red looke something ye darker by reason of its splendor. And if ye experiment bee done in ye light so yt though my eyes were shut yet some rays got through my eye lids ye \outmost/ purple would appeare of a colour inclining to blacknes by reason I suppose of ye bordering light. also {illeg} if ye pressure was not very strong ye greene \& purple/ at a would not be preceived in ye darke but it would be something lighter in ye light yn yt in other places of ye eye as at v or w, & all ye other outmost colours wthout strong pression bee but {illeg} blew. but if ye presion be strong in ye light ye apparition will but little vary from wt it is in ye darke. beyond all ye colours as {illeg}|be|tweene o & e ye light is stronger yn in other places as at v or w, because ye pressure helpes ye motion from wthout but is not strong enough to turne it to colour

10 Heate a peice of steele glowing hot, hold it over some water untill it turne from a white to a red heate then immediately quench it yt it bee neither too brittle nor soft, by being quenched too \so far as you would harden for if it be quenched sooner it/ will bee too brittle if later too soft. Then makeing ye end bright hold it over a candle yt ye end may |be| halfe an inch out of ye flame, or lay it upon a hot iron, & these colours will follow one another towards ye end of it; viz: bright yellow, deeper & reddish yellow or sanguine, a fainter blew; & a deeper blew, If it be quenched in tallow when tis yellow tis fit for gravers, drills &c: If when ye light blew is on it it is fit \for/ springs for watches If when ye deepe blew is on it, it will bee very soft.

<124v>

11 The colours succede in order according to theire more or lesse reflection of light viz: white, redd, yellow, blew, purple greene, black. Red, & purple paint theire colours far more manifestly yn blew, or greene.

Light reflected from a yellow to a blew body makes a greene

12 The sunne shineing through coloured paper or glasses \as also ye mixture of divers colours/ exhibits these colours viz yellow & blew make red

Yellow & red make Orange \or scarlet/ colour. Purple & red make scarle{t} Red & greene a darke orange Tauny. Red & blew make purple. Red & white by mixture make a Carnation

|12| ye yellow colour (made by a prisme) falling upon a blew makes a greene. blew falling upon red mak{es} a greene. It would be tried wt colours ye mixture of colours falling from 2 prismes would make.

13 Leade melted very hot & haveing ye scum taken of represents these colours viz: Blew, yellow purple, blew; greene, purple, blew, yellow, red; purple blew, yellow & blew, yellow, blew, purple, Greene mix{ed} yellow, red, blew, greene, yellow, red, purple, greene.

14 Motes in ye sunne in some positions appeare of divers colors.

15 Put as much common Sublimate into hot faire water as it can dissolve filter ye solution through cap paper yt it may be lympid. & into 2 spoonefulls of it, put about 5 drops of good limpid spirits of urine & it will be white like milke, to wch if you put in some rectified Aqua=fortis it will be transparent. more fresh spirit of urine will make it looke white but not so white as before,

16 Make a strong Infusion of broken galls in faire water filter it into a cleane violl ad more of ye same liquor to it till it be transparent. into it shake a convenient quantity of cleare but very strong solution of vitrioll & it will be black, then drop a little \cleare & strong/ oyle of vitrioll into it shakeing ye vessell well & ye liquor will become transpar{ent} wch againe will become black by ye affusion of a smal{l} quantity of a strong solution of salt of tartar.

Note, ye Corrosive liquors ( as oyle of Vitrioll) may clari{fy} |a| {illeg}liquors &|e| seperating & dividing its ts. But precipitating liquors (as salt of tartar) by uniteing theire parts make them conspicuous & ye liquor coloured.

[9]Of Imagination

I gather yt my Phantasie & ye had ye same operation uppon {illeg} ye optick spirits in my optick nerve & yt ye same motions are caused in my braines by both.

Opening my eye & lookeing in ye darke upon ye like imaginations there appeared ye like panta{illeg}|s|me {sic} as when I shut it

|5| Lookeing uppon white paper there appeared (by meanes of a strong phantasie) first a spot something darker yn ye paper wch grew dar|blac|ker & dar|blac|ker until there seemed to be a dusky red spreading almost over all ye paper {sometime} this spot would be red & & sometime blew

|6| lookeing on a bright cloude there appeared ye same phantasm as when I looked on ye white paper \onely for ye most t blacker/ untill at last I was able to make this spot glitter in ye cloude \amidst ye dusky red/ whither I looke on ye paper or cloude like ye in a cloude so bight {sic} yt my eys watered.

|7| Imploying my selfe in other exercises for two or 3 howers \an hower before sed {sic} hee being wholy clouded,/ when I thought my eye was prety well restored I repeated all ye former experiment adding this to ym yt though I shut ye distemperd eye & opened yt wth wch I looked not on ye yt I could see ye pictured on ye cloudes or other white objects almost as plaine as if I had looked wth my distempered eye ye other being shut \& every where about appeared a dusky red & blacknesse./ & wth doeing thus I have made such impress on ye optick nerve ye {sic} let me looke wth wch eye I would offered itselfe to my vew unless I set my fantasie to worke on other things wch wth much difficulty I could doe

|8| If after I had thus seene s image wth my left well eye I shut it & opened my right eye all objects would appeare coloured as when I had seene But I could not perceive any such motion in ye spirits of my left eye for all objects appeared in theire right colours to it unless <125v> when I fixed my eye {illeg} on {illeg}|ym| for yn appeared

|9| when ye impresion of was not {illeg}|too| strong upon my eye I could easily imagine severall shapes to be {where} I usually appre as if I saw them in ye s place, whence perhaps may be gathered yt ye tendere{st} sight argues ye clearest fantasie of things visible. & hence something of ye nature of madnesse & dreame{s} may be gathered

|10| When I had beene thus affected 2 days ye same \white wall/ If I looked not over nigh it where it was shadowed looked blew, where it was lesse shadowed looked red inclining to d|w|hite where it was lightest by ye rays of ye reflected fm a wall uppon it it looked white, at yt time I had beene in a darke rome for 2 or 3 howers & my eyes were made tender thereby so ye motiō made in ym would be easlier conserved & consequequently {sic} more unifo|r|me.

Of God

Were men & beasts &c made by fortuitous jumblings of attomes there would be many parts uselesse in them {illeg} {illeg} here a lumpe of flesh there a member too much some kinds of beasts might have had but one eye some more yn two & ye two eyes.

<128v>

Of Light[10]

the candle in the glasse appears & disappeare.

<129r>

Of ye Creation {is use}.

The word ב ברא wch Gen i.i. is interpreted to create something out of nothing is used Gen ye 1st v.21 where tis saide God created greate Whales \&c/, but ye matter out of wch it they were {before} \created/ did {illeg} exist before neither is it ment of creating ye soule {illeg} or forme of ye whale, for yt is not ye whale alone. & there may be but one kind of irrationall soule wch joyned wth severall kinds of bodys make severall kinds of beasts, for setting aside ye different shape of theire body beasts differ from one another but in some qualitys wch wch are called instincts of nature. now as in men whose soules are of one kind some love hate feare &c one thing some another & few men are of ye same temper wch diversity arises from {illeg} theire bodys (for all theire soules are alike) so why may not ye severall tempers or instincts of divers kinds of bea{re}|st|s arise from ye different tempers & modes of theie bodys they differing from one another more yn one mans body from anothers.. \To suppose then that God did crate {sic} divers kind of soules for divers kinds of beasts is to suppose God did more than He needed/ How yn can ye soule of ye whale be called ye whalle since before it be joyned wth ye whale tis as much ye soule of a horc|s|e & this creating yn of whales & severall other creatures must be noe but modifying matter into ye body of a whale & infusi{ng} an irrationall soule into it. Eccles: 33 ves 10 Adam was created of ye earth.

Whither Moses his saying Gen ye 1st yt ye evenig|ing| {sic} & ye morning were ye first day &c do prove yt God created time. Coll 1.16 or heb 1 ch 2 v τους ἀιωνας ἐποίησεν expoūded, he made ye worlds. prove yt God created time

<130r>

Of ye soule

Were ye soule nothing but modified matter & did memory consist in action (for it can thus consist in nothing else) wee could never call things into or memory for so long as yt action continews we must thinke of & remember yt phantasme & when yt action ceaseth & not before yn wee may cease to thinke of & remember yt p\h/antasme but how shall we call this thing into memory ye action being done & we haveing no principle wth in us to begin such a motion againe wthin us. &c

If sence consisted in reaction we should perceive things doubele or we should never se any thing before us but there would be some apparition behind us for let this perceiving body be what it will supose ye conarion it cannot be so much pressed on one side \by ye spirits/ but it will press upon ye spirits on ye other side as consequently they will presse upon it &c.

Hobbs. part 4th chap 1st. Motion is never ye weake{r} for ye object being take away for yn dreames would not be so cleare as sence. but to men wakeing things past appeare ob={scurer} then things present because ye organs being moved by other prsent objects yt {may} at ye same time motion /those phantasmes\ is|are| lesse predominant. {sic} /Resp: Then we\ should never forget any thing. 2 Phantasmes are præd{illeg}|omi|nant from ye strenght of there motion causing ym if yn there be no other cause of sence yn motion but if ye motion causing present & past phantasmes be alike strong ye effect must be ye same equall & so there would be no differences betwix sence & phantasie. all things wch wee ever perceived would be alike in our phantasie & wee should thinke of almost an immense multitude of objects at once. &c

<130v>

Of ye soule

Memory is a faculty of ye soule (in some measure for \else/ how can divers sounds, or words excite her to divers unless by memory she app \thoughts/ or 3. 4. 5 or more words beg{illeg}|e|t ye same thought in her. Perhaps shee remembers by ye helpe of characters in ye Braine, but yn how doth shee remember ye signification of those characters.

Quæe {sic}. 1 Why Objects appeare \not/ inver|s|t, Resp: t|T|he mind or Soule cannot judge ye image in ye Braine to be inversed unlesse shee perceived externall things immediately {illeg} wth wch shee might compare yt Image.

2. Why doe appeare to bee wthout our body? but paines, hunger thirst &c wth Resp: Because ye in ye image of things delineated in the braine by sight, ye bodys image is placed in ye midst of ye images of other things, is moved at or command {towars} & from those other images. &c {illeg}:

3. But why are not these objects then judged to bee in the braine Resp: Because ye image of ye braine is not painted there, nor is ye Braine perceived by ye soule it not being in motion, & probably |ye| soule perceives noe bodys but by ye helpe of their motion. But were ye Braine perceived together wth those images in it wee should thinke wee saw a body like the braine encompasing \& comprehending our selves/ ye starrs & all other visible objects. &c

<131r>

Of Quantity

If Extension is indefinite onely \in greatness/ & not infinite yn a point is but indefinitely little & yet we cannot comprehend any thing lesse. To say yt extension is but indefinite (I meane all ye extension wch exists & not soe much onely as we can fasy {sic}) because we cannot perceive its limits, is as much as to say Gods perfection & ors differ but {illeg} indefinitely because wee is but indefinitely perfect because wee canot apprehend h|H|is whole perfection

<132r>

Of Sleepe & Dreames &c

How is it yt ye Soule so often remembers her dreames by chanch otherwise not knowing{illeg} shee had dreamed, & thence whither she by perpetually employed in sleepe. whither dreames are of ye body or soule. Why are they patched up of many fragments & incoherent passages.

<133r>

Of colours vide pag 69

17 Substances belonging to ye vegetable or Animall Kingdome when lightly burned are black, when througly burned are white. As Ivory being skilfully burnt affords painters one of ye deepest{illeg} blacks they have &c. But mineralls are to bee excepted from this rule, For Allablaster {sic} if never so much burnt will turne no darker then yellow. Leade being calcined \with a strong fire/ turnes into minium which is red, & this miniū by burning turnes darker but never to a white colour. Blew, but unsophisticated Vitriol when tis burnt a little by a slow heate to friability, is white being further burnt turnes Grey, Yellow, red, & when perustum it turnes to a purple.

18 \Take/ Rectified oyle of Vitriol mixt by degrees wth a convenient quantity of ye essentiall oyle of wormewood (wch was drawne over wth stove of water in a limbec) & warily distill ye mixture in a retort, thei|r|e will bee left behind a greate quantity of dry & very black matter

Or becaus ye essentiall oyle of Winter-savory is clearer yn yt of wormewod|o||d| mix it by degrees wth about an equall quantity of oyle of Vitrioll these two cleare liquors distilled as before leave a good quantity of {illeg}|black| matter.

19 Gold & silver melted into a lumpe & dissolved by Aqua fortis ye pouder of gold falling to ye bottome appeares not yellow but black though neither ye gold silver nor Aquafortis be so, & silver rubbed on other bodys colours ym black.

20 Most bodys precipitated from ye liquor into wch they were dissolved are white, but not all.

21 The scrapeings of black horne lookes white.

22 Sulphur adust is not ye cause of blacknesse as Chimists hold, for common sulphur be either melted or sublimed turnes onely red or yellow. And \ye plant/ Camphire though very inflamable & consequently sulphureous by burning turnes to noe colour but white &c. But yn wt causeth blackness in sulphur adust.

23 A Candle looked on through blew glasse appeares greene.

24 {illeg}|P|ouder of blew bise mixed wth a greater quality of yellow orpiment makes a greene but ye particles by a microscope are discovered to retaine theire blewness & yellownesse.

25 The steame of clear Aq: Fortis, or spirit of niter is red, &c.

<133v>

26. A feather or black ribband put twixt my eye & ye setting sunne makes glorious colours.

27 |An| Acid Spirits \& juices & salts/ as Spirit of salt, or |of| Vinegar, or \of/ Vitriol or Lemmon juice, or Oyle of Vitrioll, or Aqua fortis

being droped into diversly coloured liquors & especiall{y} blew ones turne ym to red ones (as syrrup of violets impregnated wth ye tincture of ye flowers, \juice of/ blew bottles or coneweede, juice of ripe privet berrys,          ) it turnes them commnly to a red colour. But |sulphureous salts which are either Vrinous & volatile salts of Animall substances| Volatile Salts (as Spirit of Hartshorne, |of| Vrine, |of| blood, of Sal=Armoniack                               ) {illeg} or \Lixiviate/ Vnctuous or Alcalizate \& fixed/ Salts \made by incineration/ (as ye solution of Salt of Tartar, of pot ashes, of common wod|o||d| ashes, of lime=water, Oyle of Tartar,                     ) doe change ym to a Greene. |as ye red juice of bucthorne berrys|

28 Yet \either/ a Lixivious liquor, or urinous salt being poured on a solution of blew vitrioll in faire water makes it yellow & ye precipitated corpuscles retained ye \yellow/ colour when they |29| were falne to ye bottome.

29 A {great}|just| quantity of Oyle of Tartar pow|u|red into a strong solution of french verdigrease turnes it from greene to blew; a Lixivium of pot ashes turnes it to a lighter blew, & spirit of Vrin, or Harts-horne make other blews.

30 {One graine} of c|C|ochineel dissolved in spirits of urin & yn by degrees in faire water, imparted a discernable colour to {illeg} 125000 graines of faire water.

31 Most of ye Tinctures wch chimists draw \wch abound wth minerall or Vegetable Sulphur/ turne red; & \both/ Acid & Alcalizate salts in most sulphureous or oyly bodys produce a red. & blew is more commonly turned to red yn red to blew

32 Fully satiate good common sublimate wth water filter it through paper yt it be cleare, put a spoonfull of it into a cleare glasse drop in 3 or 4 drops of oyle of tartar well filtred & it will be of an Orange colour. but 4 or 5 drops of oyle of Vitriol dispersed about ye glasse by shaking it, makes ye liquor pellucid againe

<134r>

32 Some tinctures (as yt of Amber made wth Spirits of wine) appeare red or yellow as ye vessells they fill are slender or broade but cochineel dissolved as before, &{c} other liquors never looke otherwise yn Red \or of a carnation/ &c.

33 White bodys are coonly sulphureous.

34 Oyle of Tartar generally precipitates Metalline bodys corroded wth acid salts.

35 Tinge water wth faire red rose leaves into wch drop a little Minium disolved in spirit of vinegar & it will be of a muddy greene, but drop \in/ a little Oyle of Vitrioll wch though an acid Menstruum yet it will præcipitate ye leade in ye forme of a white pouder to ye bottome leaving ye rest of ye liquor above of a good red almost like a Rubie

36 Oyle or spirit of Turpentine will not mix wth water & it & water shaken together apeare white.

37 Some very corrosive \& acid/ liquors will præcipite some others, as oyle of Vitrioll præcipitates \divers/ bodys dissolved in Aqua fortis or \spirit of/ wine vinegar, wch precipitated bodys are usually \very/ white

38 Bodys will scarcely be precipitated by Alcalizate s{illeg}|al|ts yt are not first diso|s|olved in acid Menstruums

39 A leafe of Gold held betwixt ye eye & ye light appeares blew.

40 Acid salts rather dilute yellow & white juice yn turns {sic} y to red,

41 Gentle heates in chimicall operations rather produce rednesse yn other colours {illeg}|in| digested menstruums not onely sulphureous (as spirit of wine) vid: sec: 31. but saline as Spirit of Vinegar

42 Alcalizite salts are wont to precipitate wt acid salts dissolve

43 An Acid salt doth seldom restore a Vegitable substance to ye colour of wch an Alcalazite deprived it.

44 The acidity of spirit of vinegar is destroyed by working on Minium, (or perhaps on Crabs claws)

45 Put some solution of Minium into a spoonefull of ye fresh tincture of logwood to turne it \deeply/ purple <134v> precipitate 12 ye leade wth spirit of sa{c}|l|=armonick wch precipitacon \as well as ye supernatant liquor/ looks {illeg} purple (by reason by reason {sic} of ye predominance of ye tinged particles over ye white) yn power in some spirit of salt warily & ye precip{:} by Sal=Ar: is of a violet colour at ye botome, ye precip{:} by spirit of salt is white \& carnaco{illeg}|n|/ in ye midst, & ye top yellow or red.     vide sec 35

46 That ye colour of a body bee altered by a \cleare/ liquor tis commonly required yt it have salt yet faire water powred on ye grey & friable calix of powdred Vitriol melted by a gentle heate till {illeg} it colour change & ye liquor being set by in a close violl for some days it will tune to a vitriolate colour

47 Take Lignum Nephriticum (ye infusion of wch in faire water is good against ye kidn stone of ye kidneys) put a handfull of thin slices of it into 3 or 4 pound of pure spring water after it hath infused there a night put ye water into a cleare violl, & if you see ye light through it it appeares of a golden colour (excepting \sometimes/ a sky coloured circle at ye top) but if ye infusion was too strong ye liquor will then appeare darke & reddish. But if ye liq your eye is twixt ye liquor & light it appeares ceruleous: & Acid salts destroy ye blew colour & sulphureous saltes restore it againe, wthout making any change in ye golden colour. Which may bee usefull to ye {illeg} finding whither bodys abound more wth acid {illeg}|or| sulphureous Salts.

48 The same may be done by Spirit Sirrup of Violets {illeg} impregnated wth ye tinture of ye flowers. For an acid salt turnes it from blew to red but sulphureous one from blew to greene. vide sec 27.

49 Haveing found yt a sulphureous salt is predominant in a body it may be knowne whither yt salt be {illeg} Vrinous (i. e. volatile salts of anim{al} <135r> or other substances wch are contrary to acid ones) or Alcalizate in ye 32d sec. that is into sublimate disolved |in| faire water put an {illeg} Alcaly & it turnes it to an Orange Tauny, but urinous (or salsuginous) salts turne it to a pure white

50 ye same liquor viz oyle of Vitriol) powred into a lixivium in wch crude {illeg}|a|ntimony has beene newly boyled turnes it from a cleare to \a/ yellow colour, wch sec: 32 turned a yellow to a cleare one.

51 There be flat peices of \a/ certaine kind of glase wch exhibits ye Phenominon of lignum Nephriticū.
