A 3 TO T O T H E READER Concerning the Third, and this Fourth Edition. I Otwithflandtng that a Book is more complete and va- luable hy /Additions and Amendments^ yet I think that many and great Additions are an hardjhip and mjuflice to the Pur cha- fers of a former Edition • and there- fore have in thts^ and in the for ego- tng Editions^ avoided it as much as well I coiddy although fome of my learned PREFACE. learned Friends zvould have perfuaded me to ity and alfo contributed their Obfervations. But fyet from what I have faid in the Preliminary Difc. p. 3. it will^ I doubt not^ he expeBed^ that I Jhould give fome account of the Obfervations which the long and good Qlaffes in my Handsy have afforded me Jince the lafl Edition of this Book. But I have little to boafi of here^ having (befides the old former Com" plaint of the want of a long Pole to manage Mr. Huygens'^ Glafs with) many great hindrances in my Obfer- vations, partly by a very dangerous Fit of Sicknefsy which hung long a- hout me 'y and partly by my neceffary Affairs callmg me to matters of ano^ ther nature. But fome of the mojl confiderable of my Obfervations were thefe. I. Viewing Venus with Mr. Huy- gens'5 Glafs divers nights^ when near A 4 her PREFACE. her Perigee ^ and much horned , I thought I J aw Anfradus, or Rough- nefles on the concave part of the en-^ lightened edge (fnch as we fee in the New Moon) which 1 have reprefent- ed as nearly as I could in Fig. 12. 2. In n^y frequent views of Jupi- ter, / find his Belts to have great variations • that they change their Places ; that their Breadths alter ^ he^ ing fometimes broader^ fometimes con- fiderabl'^ narrower ^ that fometimes they are more in number ^ fometimes fewer ,• fometimes they are darker and blacker j fometimes thin and only like a Mifl, Towards the Poles of Jupiter are the greatefi Alterations^ there being fometimes few ^ or no Belts toward one or the other Pole ; fome- times one quite acrofs the Polar Parts^ another reaching but half or a Part of the Way. And even about the middle^ or Equatorial Parts of Ju- piter, where there are always Belts (and PREFACE. (a?id commonly tivo) yet thefe vary <: on fide r ably. Sometimes they are nearer one another^ fomettmes far^ ther aftmder : fomettmes they are con ftder ably broader^ efpe dally that nearefl the middle j fomettmes as con- ftder ably narrower: Sometimes they both advance towards one Pole ^ and then recede towards the other oppofite Pole. Of many of thefe Appearances I took Draughts^ and defigned to have enquired whether they had certain Periods ^ but want of health and lei-' fure prevented me. And not only the Belts, hut the Spots alfo of Jupiter vary greatly^ I do not mean the Spots occafioned by the Shade of the Satellites, but fuch as are on the very Disk: which are fomettmes of one form^ fomettmes of another , and oftentimes none to be feen at all^ although the fame Face of Jupiter Jhotdd he towards us. 3. The PREFACE. 3 . The lafl thing I /ball mention is the Nebulofe, which are thofe gla- ring whttiflo appearances^ feen with our Tekfcopes in Andromeda'^ Girdle, Herculcs'5 Back, AntinousV Foot, Orion's Sword, in the Centaur, Sa- gittary, ^c, which appear through the Tele/cope^ fomewhat after the manner^ as Cor Cancri doth to the naked E'ye, Thefe Nebulofe / have often view- ed with Glaffes of very different lengths y particularly that in pcde An- tinoi with Mr. Huygens'j; but I con^ fefs that I coidd never dtfcern what they are ^ neither indeed could I per- ceive any great difference m their ap- pearances through a very good Glafs of about 1 4 foot^ and others of 7^0 and ^ofeet^ yea Mr. Huygens'5 of 116. But indeed the grand obflacle to all my I'' lews ivith Mr. Huygens'5 Glafs was the lapours near the Horizon^ which not only ohfcured the ObjeB^ hut PREFACE. hut caufed fo great a trembling and dancing thereof^ as made it no lefs difficult to he diflinclly and accurately viewed^ than a thing held in the hand isy when danced and Jhaken hack- wards and forwards. By this means my ExpeBations from Mr. Huygens'^ Glafs were frequently frustrated ^ ex- cepting in nights that were more than ordinarily ferene and clear y which was commonly in fuch as were the mojl intenfely Frofly and Cold, Finding it therefore unlikely that I Jhould do much more with Mr, Huy- gens'5 Glafs than I had done, 1 refto- red it to the Royal Society which lent it me^ (and to whom Mr, Huygens be- queathed it by his lafi Will) content- ing my f elf with the View sit had given mey and that I had difc over edit to be an excellent Glafs ^ which Dr. Hook, and fome others of our beji fudges took to be good for nothing. And PREFACE. And now having given this account of my Ohfervations^ and alfo Jhewed what hinder' d my completing of them (which may excite farther Enquiries y as well as ferve to vindicate my felf) I floall recommend thefe things to fuch as have good Glaffes^ particularly to the Diligence and Accuracy of my ve- ry ingenious Friend ^ the Reverend Mr, Pound, into whofe hands the Royal Society have put that noble Be- quejl of Mr. Huygens, and zvho is fo well accommodated for raifing and u- fing that Glafsy as to have feen (among other confiderable things) the five Sa- tellites of Saturn ; which I confefs I could never reach ^ nor above three of themy that I could be fure were Satel- lites: I fay that I could be fure were fuchy hecaufe it is not very eafy to di- flinguifh ivhich are Satellites, and which are fmall Telefcopick Stars, which very frequently fhew themfelves in a Glafs oj fuch goodnefs as that is. I re^ PREFACE. / remember that I once verdy thought I had found out [even Satellites ofSs.- turn, wuh this very G/a/s of Mr. Huy- gens, fo regularly were they placed in refpe5l of Saturn. But z^hen I came to examine thetn the follownifr ?jtghts^ I found that there were real- ly no more than tzvo Satellites, the re/i being fmall Fixt Stars. But Mr. Pound'5 Skill and Exa&nefs in fuch Ohfervations., is I know Jo great ^ (and I may add that of my fagacious friend Dr. Halley too^ who I hear hath feen the fame) that I do not fay this by way of Caution to them^ aU though it may ferve as fuch to many others. And now for a Clofe I fhall take this opportunity of pubhckly owning^ with all honour and thankfulnefs^ the generous Offer made me by feme of my Friendsy eminent m their Stations^ as zvell as Skill and Abilities in the Laws^ who would have made me a Prefent PREFACE. Prefent of the May-pole in the Strand, (which was to he taken doivn) or any other Pole I thought convenient for the management of Mr. Huygens'5 Glafs, But as my incapacity of ac- cepting the favour of thofe noble Me-- coenates, hath been the occafion of that excellent Glafs being put into bet^ ter hands^ fo I ajfure my felf their expectations are abundantly anfwer^ ed^ by the number and goodnefs of the Ohfervations ^ that have been ^ and will be made thereivith.

And when my Hand was in, I new-made fome part of it, and added many new Obfcrvations of my ovv'n, which I then had lately made with fome ve- ry good long Glaffes I had in my hands ^ one of Campam's gxinimg-^ and others of Enghfh work, which exceeded it ; but efpecially one of Mr. Hiiygens's of above 120 ic^t^ which few for goodnefs do furpafs. Of The Author's Obfervattons, iii Of thefe Obfervations the Rea- der fliould have met with many more (and I believe Tome of my in- genious Friends do expc6l more) but that I lie under two inconveniences. One the want of an open free Ho- rizon , my Habitation being fur- rounded much with Trees. The o- ther, and indeed the chief, the want of a long Pole of loo or more feet, to raife my long Glafs to fucli an height, as to fee the Heavenly Bo- dies above the thick Vapours j which much obfcure all Objeds near the Horizon, efpecially when viewed with fuch Ion? and good Glaffes. Buc fince that, two very dangerous fits of Sicknefs, and the increafe of my Age, (both which have much impaired my Sight) have rendered me uncapable of fuch Obfervations, efpecially at fuch Seafons of the Night and Wea- ther, as are fittcil for viewing the Heavenly Bodies, a 2 And iv The Author's Ohfervations. And therefore if I have not fuffi- clently anfwered the expedations of fome of my learned and ingenious Friends, I hope they will excufe me, and believe it to be more my Cala- mity than Fault that I have done no more; cfpecially among fuch Pla- nets as have advantageoufly prefent- ed themfelves, as SaUirn particular- ly hath, whofe 5 or more Satellites it may be expected I have feen ,• but I could never reach but three of them, and they only when there were but few Vapours. And as for the Spots in Mars and Vevius^ and their Motion round their own Axes, after 1 had a good Furniture of ex- cellent GlafTcs, I had not any good Views of thofe Planets before my Sicknefs, by reafon of the too great diftance oi Mars from the Earth, and the proximity of yenns to the Sun, and the cloudy Weather, and the fmall altitude which Fen^ts had above the The Author's and others Obfervat. v the Horizon about that time. But however what is here want- ing in my own, is fufficiently made up from the Obfervations of others. Of which the learned World hath good Store^ fince the Invention of the Telefcope i which as it hath made ample difcoveries of the Works of God, fo hath laid open a new, and a far more grand and noble fcene of thofe Works than the World before dreamt of, and afforded us a far more Rational Syfteme of the Hea- vens and the Univerfe, than was be- fore entertained. And forafmuch as I have fre- quent occafions in my following Book to fpeak of, and according to this, and fome of the other Syftemes, it is neceffary I fliould, by way of Preface, give fbme account of them, to enable fuch Perfons to underftand my Book as are unacquainted witk Aftronomical Matters. a 3 Amonq vi Of the fever al Syfl ernes Among all the various SyftemeSj I need take notice only of three, the Ptolemqtck^ the Coperntcan^ and the New S'yfleme, Of each of which in their Order. Of the Ptolemaic k Syfteme, In the Ptolema'tck Syfleme the Earth and Waters are fuppofed to be in the Center of the Univerfe 5 next to which is the Element oi Air, and next above that is the Element of Fire j next that the Orb of Mercu- ry^ then that of Venus^ then that of the Sun \ and above the Sun's Orb, thofe of Mars, Jupiter, and Saturn-^ and above them all, the Firmament or Orb of the Fixt Stars ; then the Gyjialline Oris ^ and laftly the Coelum Empyreum, or Heaven of Heavens. All thefe maffy Orbs, and vaft Bodies born by them, are, in this Syfteme^ fuppofed to move round of the Univerfe, \\{ round the terraqueous Globe once in 24 hours: and befides that_, in fbme other certain periodical, times. For the effecting of which Motions, they were forced to contrive fuch Circles as they called Eccentrkks and Epicycles, eroding and interfe- ring with one another ,• which I could not reprefent in fo narrow a compafs as Fig. i. is, which is a Scheme of this Ptolemakk Syjieme ; which is univerfally maintained by the Penpatetkk Philofophers. Of the Copernican Syfieme, The next Syfleme is the Pytha- gorean or Copernican^ being invent- ed as fome imagine by Pythagoras himfclf. But Diogenes Laert'ms (a) expreflly faith, That Pythagoras's opinion was, That the World was (a) Lib. 8. in Pythagora. a 4 roundj viii The Copernican Syfteme. round , contaimrig the Earth tn the midjl of It. And by P/my's account (h) of Pythagoras his Diftances, and Orders of the Planets, this fcems to have been his opinion. But the Time Laertms (c) affirms Ph'ilolam the Pythagorean ryju Yyjv yj^/Blc^ai zarcl K'J- KAOv^ TT^uTov BLTreTv 01 Sly 'I'/Jtccv ^'j^a~ yjciov (paab' to have been the firjl that Jciid the Earth vjas moved m a Circle: but jo me fay Hicctas the Sy- racufian. So Plutarch in his l^ife of Nunia^ fpcaking of Numa'^ building The Temple of Veil: a, fiich, he bu'tlt it rounds and that a continual hire was kept therein in imitation of the figure of the Earthy or rather of the ivhole World it felf ^ the middle of which the Pythagoreans (not Pytha- nor as) take to be the Seat of Fire. This Syfl:eme (whoever was the Invcnter of it) Copernicus a Canon (b) Nat. Hrft. L. i. c. 21,21. (c) Ibid, in Philolao. of The Copcrnician Syfleme. ix oiTouratn rcftorcd about the begin- ning of the fifteenth Century, and was followed therein by many confider- able men, as Khetkus^ Moefilmus^ Kepler y Rot h man ^ BulUaldus^ Lanf- berge^ HertgomuSy Schickard ^ Gaf- fenduSy Galileo, and others. The lafl: of which (by the ill will and inftigation of Pope Urban VIII. as 'tis fuppofed) had the misfortune to fall under the cenfure of, and to have his Coperntcan Tenets condemn- ed by, the Inquifition, and was for- ced to abjure them. The particu- lars of which, if the Reader hath a mind to fee, he may find them in Rtcciolis Aim age fi (d). According to this Syfteme, the Sun is fuppofed to be in the Center, and the Heavens and Earth to revolve round about him according to their feveral Periods : firft Mercury in (d) Lib inhiavir, vid. Buxtorf. Lexicon. Going Copernicus anfwered. xxvii Going forth is faid to be from the end of the Heaven^ avid hts Circuit to reach to the ends thereof: as thoupli the Heavens had two Extremities, or was (as the Ancients fanfied the Earth to be) a long large Plane bounded by the Ocean, under which they imagined the Sun betook him- felf, and was thence faid Ttngere fc Oceano^ to dip himfelf in the Ocean when he Set. And as in thefe places of Scri- pture the Sun is faid to move ,♦ {o in the other places he is faid toflandfiill^ and to go backward. But we dial I find that very abfurd conciufions would follow the taking thofc Texts in a ftrid: literal Scnfe. For in Jo- Jhtia the Sun is ordered to fland fiill upon Gibeon, and the Moon in the valley of Ajalon. But it would be very abfurd to take this in a literal Senfe, and imagine tliofe two greac Luminaries were confined to thofc mo xxviii Ohje^itons againfl two places, otherwife than in appear- ance to the vidoiious Ifraelites. And if fo confiderable a part of the tranP adion be fpoken according to its appearance, why not the whole? Why might not this Station as well be an arreil of the Earth's Motion as of that of the Heavens, if the whole Miracle was not (as fome not improbably think) effeded by means of fome preternatural Refractions, or extraordinary Meteors, fefc. An D fo for the Recefs of the Sun, or its Shadow in Hezekiah's cafe, that which in appearance feemed to be the adion of the Sun is by divers learned men thought to have been the effed of fuch like extraordinary Refradions or Meteors, as I mention- ed in the laft cafe : or if it was a real Recefs ; why not of the Earth, rather than the Sun and whole Hea- vens ? Thus Copernicus anfwered. xxix Thus having anfwered the par- ticular Texts, it doth not appear that the Scriptures oppofe the Coper- nkan S'y^eme, but that thofe palTa- ges which feem to do fo, are fpoken more according as things appear than as really they are. For as St. H'terom faith (h)j Confmtudtms Scripturarum efl It IS the cuHom of the Scriptures, for the HiHortan fo to relate the opi- nion men had of man^ matters^ as at that time thofe matters were by all people taken to be. And in another place (i) There are many things in the Holy Scriptures^ which are fpoken ac- cording to the opinion of the time in which they were done^ and not ac- cording to their Reality, And this is no other than what is very reafon- able, and fuitable to the end and de- fign of the Holy Scriptures, which (h) Hieron. in Matth. c. 13. (t) In ^srem, i8. as jcxx Ohj eel ions againji as 1 have faid, is rather to inftrud men in Divine and Moral DoclrineSy than Pbilofophical Truths, And a- grceably hereto St. AugiiHme anfwers this very doubt concerning the Mo- rion of the Heavens (t). Some of the Brethren (faith he) move a ^eftton^ zvhether the Heavens jland jitllor are moved ^ hecaufe^ fay thejy if they are moved ^ how is tt a Firmament? and if they jiand fiill^ how do the Stars y which are believed to be fixt in them y revolve from Eafl to PVejl^ the Nor-- them Stars defcrihmg leffer Circles ' near the Pole? — To which y faith he, / anfiver^ That thefe things do great- ly require fever al fubtile and lahori- CHS Reafons^ to difcover truly ivhether the matter be fo, or not fo. For the entering upon^ and dif cuffing of which ^ I have neither timey neither is it fit (!) Augiift. dc Genefi ad Literam. L. a. cio. « it Copernicus anfwered. xxxi It Jhould he done to fuch as we defire to tnUruB in the way of Salvation^ for the necejfary benefit of the holy Church, Having thus an(wered the Ob- jedions from Scripture, I fliall in the laft place confider thofe brought from Senfe and Philofophy. The Objcdion from Senfe is. That we fee the Heavenly Bodies adually to move, and therefore ought to beheve they do fo. But there is no weight at all in this, be- caufe whether we our felves, or the Objed: moveth, it amounts to the fame. As is manifcft to any one car- ried in a Boat or Chariot ^ the Pro- greflive motion of v/hich, produceth the appearance of a Regreflive mo- tion in the unmoved Objeds we look upon ,• according to VirgiH dcfcrip- tion of JEneas and his company's leaving their Port. (k) Pro- XXX ii ObjeBiom aga'mjl (k) Proveh'tmur portu^ temeqiie nr- hefque recedtint, i. e. Both Land and Towns receded when we left our Port, As for the reafon hereof, I fliall refer to the Op- ticians, particularly the famous Kep- ler^ who in his Optices AUronom. hath defignedly handled this Point. The Objedions from Philofophy are too numerous to be diftindly an- fwered, efpecially (uch as feem very frivolous, particularly thofe ground- ed on a fuppofition of the Verity of the Art^otelian Philofophy, as the Immutability and Incorruptibility of the Heavens, 6fr. For anfwers to which I rtiall refer the Reader to G^- ///^o's Syftem. Mund. But for fuch Objedions as feem to have fome reafon in them, they are chiefly thefe, That if the Earth be moved (k) i^neid. L. 5. i^./z. from Copernicus aufwered, xxxiii from W. to E. a Bullet (hotWeftward would have a farther Range, than one fliot Eaftward j or if (hoc N. or S, it would mifs the mark ; or if perpen- dicularly upright, it would drop td the Weftward of the Gun. That a Weight drop'd from the top of a Tower would not fall down juft at the bottom of the Tower, as we fee it doth. That Birds flying towards the E. would be hindered in their Flight, but forwarded in flying the contrary way,- with much more to the fame purpofe. But not to enter into a Detail of Anfwers that might be given to the preceding Objedi- ons from the Laws of Motion, and the Rules of Mechanicks and Ma- thematicksj I fliall only make ufe of the mod: ingenious Gal'il(eo'% plain Experiment, which anfwereth all or moft of the Objcdions (I), Shut ^ faith he, your felj up with ^^Qur friend (0 Syflem.. Mimd. Dialz. xxxiv Objechons cigatnfl in the Great Cahm of a Ship^ toge- ther with a parcel of Gnats and Hies^ and other little winged Creatures, Procure alfo a great tub of Water ^ and put Fifhes therein. Hang alfo a Bottle of IVater upy to empty it felf drop by drop into another fuch Bottle placed underneath with a narrow neck. IFhiljl the Ship lies fill, dili- gently ohferve how thofe little winged Creatures fly with the like fviftnefs towards every part of the Cabin \ how the Fifhes fwim indifferently towards all fides • and how the defending Drops all fall into the Bottle under- neath. And if you throiV any thing to your Friend, you need ufe no more force one way than another, provided the Dijlances be equal. And if you leap^ you will reach as far one way as the other. Having ohferve d thefe particulars whiljl the Ship lies jiill^ make the Ship to fail with what Ve^ locity you pleafe, and fo long as the Motion Copernicus anfwered, xxxv Motion is uniform^ not fluBuattng this way and that way^ you jh all not per- cetve there is any alteration in the a- forefaid effeBs j neither can you from them conclude whether the Ship mo^ veth or flandeth fiilL But in leaping you /ball reach as far on the Floor as you did before , nor by reafon of the Ships motion^ fhall you make a long- er Leap twards the Poop than the Prow J notwithfianding that ivhilfl you were up m the airy the Floor under your feet had run the contrary way to your Leap, And if you cafi any thing to your comp anion ^ you needufe no more Jlrength to make it reach him^ if he fhould be towards the ProWy and you tozvards the Poopy than if you food m a contrary pofition. The Drops fhall all fall into the lower Bot- tle y and not one towards the Poopy al- though the Ship fhall have run many feety zvhilfl the Drop was m the air. The Fijhes in the IVater fhall have c 2 no xxxvi OhjeBtom agawjl no more trouble tn fwtmmwg towards the forepart oj the Tub^ than towards the hinder part^ but fhall make to- wards the Bait with equal Swtftnefs^ on any fide oj the 7itb» And lajily the Gnats and Flies Jhall continue their flight indifferently towards all parts y and never be driven together towards the fide of the Cabin next the Prow^ as ij wearied with following the fwift motion of the Ship. And if by burn" ing a few gt ams of Incenfe^ you make a little Smoak^ you fhall perceive it to afcend on high^ and hang like a Cloudy moving indifferently this way and thaty without any inclination to one fide more than another. The caufe of which correfpondence oj the Effeclsy isy that the Ship's motion is common to all thtngs contained tn tt^ and to the Air alfo : I mean when thofe things are fhut up in the Cabbin : but when they are above Deck in the open Air , and not obliged to follow the Copernicus anfwered. xxxvii the Ship's cotirfe, differences more or lefs may ar'tfe among the forenamed EffeSs. Thus GaliUo by this one Ob- fervation hath anfwered the moftcon- fiderable Objedions deduced from Philofophy againft the Motion of the Earth. And thus much (hall fuffice for the Explication and Proof of the Copernkan Syfieme -^ efpecially that part of it relating to the Solar Sy- fteme. Which things I have more largely than ordinary infifted on, for the fatisfadion of many that I am fenfible doubt of them, and par- ticularly fome of my Friends (and thofe not unlearned too) who may be apt to read my following Book with prejudice wherefoever 1 favour the Coper mean Notions. Of the New Sy fteme, A N D now I pafs from the Second Syfteme to the Third, which is cal- c 3 led xxxviii Of the New Syfleme, led the New Syfteme^ and by fome the True Syfteme 5 which extends the Univerfe to a far more immenfe compafs, than any of the other Sy- ftemes do^even to an indefinite Space ; and repleniflies it with a far more grand Retinue than ever was before afcribed unto it. This New Syfteme is the fame with the Copermcan^ as to the Sy- fteme of the Sun and its Planets ,• as may be feen by the Scheme of it in Fig. 3. But then, whereas the Coper- tncan Hypothefis fuppofeth the Fir- mament of the Fixt Stars to be the Bounds of the Univerfe, and to be placed at equal Diftance from its Cen- ter the Sun ^ the New Syfieme fuppo- feth there are many other Syftemes of Suns and Planets, befides that in which we have our rcfidencc : name- ly, that every Fixt Star is a Sun, and encompaffcd with a Syfteme of Pla- nets, both Primary and Secondary, as well as ours. ^ These Of the New Syfleme. xxxix These feveral Syftcmcs of the Fixt Stars, as they are at a great and fufHeient Diftance from the Sun and uSj^ fo they are imagined to be at as due and regular Diltances from one another. By which means it is, that thofe multitudes of Fixt Stars appear to us of different Magnitudes, the neareft to us large ; thofe farther and farther, lefs and lefs. Of thofe Syftemes of the Fixt Stars I have given a rude reprefenta- tion '':i Fig. 3. together with that of the Sun j which may ferve to give an unfkiiful Reader fome conception of the ftate of the Univerfe ^ although there be but little likenefs in it, for want of room to lay out all the feve- ral Syftemes in due proportion j which is necelTary to a true reprefentation of the matter. I N this 3d Fig. the Fixt Stars with their Syftemes (reprefented by little Circles, about thofe Stars, which c 4 Circles xi Of the New Syfieme. Circles fignify the Orbits of their re- fpedive Planets) are placed without the limits of the Solar Syftemej and the Solar Syfteme is kt in the Cen- ter of the Univerfe, and figured as a more grand and magnificent part thereof. And fo it may be looked upon by us, by reafon of its proxi- mity and relation to us. But whe- ther it be really fo, whether it be in the Center of the Univerfe, and whe- ther among all the noble Train of Fixt Stars, there be no Syfteme ex- ceeding ours in its magnificent Re- tinue of Planets, both Primary and Secondary, and other admirable Con- trivances, is a difficulty, as out of the reach of our GlaiTes, fo confequent- ly above our ability to fathom, al- though not at all improbable. But be the various Syftemes of the Uni- verfe as they will as to their Dignity, it is fufficient that in all probability there are many of them, even as many Of the Neiv Syjieme. xli many as there are Fixt Stars, which are without number. This Syfteme of the Umverfe^ as it is phyfically demonftrable, fo is what, for the mod part, I have fol- lowed in the enfuing Book, but not fo rigoroufly and obftinately, as ut- terly to exclude or oppugn any o- ther Syileme,- becaufe as the fVorh of G D are truly great, and fuffi- ciently manifcft their excellence and magnificence in any Syfteme,- fo I was wilHnCT to fhew the fame in fuch Syftemes as I had occafion to (peak of them in ^ becaufe I would not of- fend, and confequently not bar the force of my arguments upon fuch Readers, as might happen to be wed- ded to the Arijhtehan PnnctpleSy or prejudiced to the Ptolematck^ or any other Sjfieme : Not that I had my felf any doubts about this New Sy- fieme^ but think it to be far the moft rati- xlii The Probahitity of rational and probable of any, for thefe reafons. 1. Because it is far the moft magnificent of any ,* and worthy of an infinite CREATOR: whofe Power and Wifdom as they are with- out bounds and meafure, fo may in all probability exert themfelves in the Creation of many Syftemes, as well as one. And as Myriads of Syftemes are more for the Glovy of GOD, and more demonftrate his Attributes than one ,• fo it is no lefs probable than poffible, there may be many befides this which we have the Pri- vilege of living in. But it is very highly probable the matter is fo, by reafon, 2. We fee it is really (b, as far as it is poffible it can be difcerned by us, at luch immenfe Diftances as thofe Syftemes of the Fixt Stars are from us. Our GlafTes are indeed too weak the New Syfieme. xliii weak fo to reach thofe Syftemes, as to give us any aflurance of our fee- ing the Planets themfelves, that en- compafs any of the Fixt Stars. We cannot fay we fee them adually mo- ving round their refpedive Suns or Stars. But this we can difcern, vtz. That the Fixt Stars have the Nature of Suns, as I have made probable in Book. 2. Chap. 2. As alfo that there are fome things very like unto Pla- nets, which fometimes appear and difappcar in the regions of the Fixt Stars ,• as I have {hewn in my difcourfe oi New Stars^ Book 2. Chap. 3. But befides what I have faid there, I have this farther to add from fome late obfervations I have made fince my writing that part of my Book; and that is. That the Galaxy being well known to be the fertile place of New Stars^ the region in which they commonly appear, I am much incli- ned to be of opinion, that the Wh'tte^ nefs xliv The Author'' s Obfervatmis nefs there, is not caufed by the bare Light of the great number of Fixt Stars in that place, as hath common- ly been thought, but partly by their Light, and partly (if not chiefly) by the Reflexions of their Planets ; which ftop and reflc6t:, intermix and blend the Light of their refpedive Stars or Suns, and fo caufe that Whicenefs the Galaxy prefents us with j which hath rather the colour of the reflcded Light of our Moon than the Primary Light of our Sun. And that there are Planets e- nough for this purpofe, I fufpedt be- caufe I have fome reafons to imagine that there are many more New Stars in the Milky way (all which I take to be a kind of Planetary Globes) than have ever yet been taken no- tice of, and that many of thofe pro- digious numbers of Tclefcopial Scars vifible there, are of the numbers of Neiv Stars or Planets^ and not of of the Galaxy, xlv Ftxt Stars only. This Sufpicion I have for fome time had, but efptci- ally lately from my Views of the New Star that now begins to difnp- pear in the Swan's IS'eck. Which gave me occafion to infped: fome other parts of that Conftellation, mod parts of which are well reple- niftied with a numerous train of fmall Stars. Amongft which, fometimes methoughts more have prefcnted themfelves through one and the fame Glafs, and fometimes 1 have mift fome I thought I before faw : and fometimes alfo methoughts 1 have feen them nearer to, and fometimes farther off thofe Stars that did con- ftantly prefent themfelves. But as thefe things are to my fclf novel, and what 1 confefs I have rather Sus- picions of than Certainty, 1 (liall re- fer them to the future Obfervations of my felf, and others, for their Con- firmation j efpecially becaufe thofe Appro- xlvi The Author's Ohfervattom Approximations and RecefTes of fome of the little Stars I fpake of fuit not with the Obfervations of fonne very- eminent Aftronomers. These Obfervations as they will open to us a new, and admirable Scene of the Heavens (if it be as I imagine) fo I earneftly recommend- ed the Enquiry into it to fuch as de- light in thofe matters. For the do- ing of which, I conceive it may be fufficient, and the eaficft courfe to make the Obfervations in fome one part of the Milky-way, as in fome part of the Swan for inftance,- and I would advife that an Area of the Heavens may be taken in, continu- ing as much or a little more than fal- leth within the compafs of the Tele- fcope you make u(e of; Which was the way I pradifed, and that part of the Heavens, in which I obferved. All the Stars that fall within this A- rea, an exad Map muft be taken of, ^ which of the Galaxy. xlvii which will fliew when any Variations happen. And for taking in the larger Area of the Heavens, a Glafs of 6 or 8 Feet is fufficient, and rather better for the purpofe than longer Glafles, which take in lefs, and are more troublefome in ufing. H Av I N G thus reprefented the State of the Umverfe according to the New Syjleme of it, the ufual Que- ftion is, what is the ufe of fo many- Planets as we fee about the Sun, and fo many as are imagined to be about the Fixt Stars? To which the anfwer is, That they are Worlds^ or places of Habitation, which is concluded from their being habitable^ and well provided for Habitation. This is pretty manifeft in our Solar Planets, from their being opake Bodies as our Earth is, confifting in all probability of Land and Waters, Hills and Val- leys,having Atmofpheres about them. Moons miniftring unto them, and being xlviii That there are Seas being enlightned, warmed and in- fluenced by the Sun ^ whofe yearly Vifits they receive, for Seafons; and frequent Returns or Revolutions, for Days and Nights. All which parti- culars are fully treated of in the fol- lowing Book, and need not therefore to be anticipated here. Only there is one thing, which for want of Ef- ficient Obfervations, I could not lb fully (peak of as I would ,• and that is concerning the Seas in the Moon^ in Book J. Ch. 4. Note a, whofe very exiftence Mr. Huygens (m) denies, faying, Marinm veto fimilttudmem dlk nullam reperio^ 8cc. i. e. In the Moon / yzW r/o likeiiefs of Seas^ al- though Kepler and mojl others are of a different opinion. For thofe vafi plane regions^ which are much darker than the Mountainous parts ^ and are commonly taken for Seas ^ and bear (m) Cofmotheros, p. 114. the in the Moon, xlix the names of Oceans ,• in thofe very places viewed with a long Telefcope^ I find httle round Cavities with Jha- dows falling withm them^ which can^ not agree with the Surface of the Sea : as alfo thofe very large Fields when carejiilly viewed^ do not prefent us with a Superficies altogether equaL Wherefore thefe cannot be Seas^ hut are fuch places as confifi of a lefs bright matter than that which is in the more hilly parts^ but in which aU fo there are fome places brighter than others. Thus the mofl; ingenious Mr. Huygens^ who then proceeds io fliew that there are neither Rivers, Clouds, Air, or Vapours. But that there are Seas or great Collcdions of Waters, and confe- quently Rivers, Clouds, Air and Va- pours in the Moon, I fhall make out from fome of my own Views and Obfervations; many of which were made with Mr. Huygens's own long d Glafs 1 That there are Glafs before mentioned : through which, and all other long Glaffes, inftead of imagining the Lunar Spots to be unlike Seas, I have always thought them to look more like Seas, than through fliort Glafles. It is true indeed that in thofe Spots we take to be the Seas, there are fuch Cavities as Mr. Huygem fpeaks of, or rather Mountains with ftiaded Cavities in them, as alfo fome parts lefs dark than others. Thus in the Southerly Parts of the Lunar Euxme and Mediterranean^ in the Stntis Strboms^ the Egyptian ^ and di- vers other Seas, there are feveral fuch Parts that appear more lumi- nous than others, fome having the appearance of Rocks and Iflands, fome of large Shallows, particularly towards the Shores, and efpccially in the Seas bordering on the Conti- nentvS, fuch as the great Southern Continent of the Lunar ^gjp^ and- Paldefi'ine, Seas m the Moon, li PaUJitne, But this is no conclu- five argument of thofe parts not be- ing Seas 5 becaufe they may be Seas having many Iflands and Shallows in them. But then in other Parts, and even in fome Parts of thefe laft na- medj the Spots appear darker^ and with buc few of thofe Eminences or Iflands J thofe brighter or (hallo^ Parts. Thus the Northerly Eux'tne and Mediterranean^ the Palus Mdeo^ tisy and many other of thofe Lunat Seas 'y few of thofe Parts that have the afpe6t of Iflands or Shallows aire to be difcerned in them, only one here, and another there, at confider- able dift:ances from one another. And in this very manner I doiibc not our terraqueous Globe would ap- pear, if viewed at the Moon, or at fome miles aloft. We {hould there perceive our deep Oceans would be of a darker colour, like the darker Spots of the Moon ; and the fingle d % Ifles In That there are Seas Iflcs of St. Helena and /Ifcerifion^ and the more numerous ones of Ladro^ neSy Canaries^ ^zoreSy 3cc. to have the fame appearance that the few fcatter'd Iflands have in the deeper Lunar Seas : and our Shallow Seas with their numerous Rocks and I- flands difperfed about them, efpeci- ally towards the Continents, would look as thofe in the Moon do. That a Reader unacquainted with the Geography of the Moon, may apprehend what I have faid here and elfewhere, concerning the Parts and Appearances of the Moon, I have reprefented them in Fig. lo. and ii. In Fig. 10. the Face of the Full Moon is reprefented, its bright and dark Parts with mod of the Names given them by Heve/ius, whofe Lu- nar Geography is juftly the moft fol- lowed. In Fig. II. I have reprefent- ed the appearance of the Moon's Edge on this laft Nov, 4. 17 14. foon after m the Moon, liii after the Quadrature, for the expli- cation of what is faid concerning the Evennefs of the Surface of the Lunar Spots in B. 5. Ch. 4. Note^. It may be there obferved that the Surfaces of all the Seas appear ftrait and level, only the top of here and there a Rock or Ifland prefents it felf at a fmall diftance. Thus the Surface of the Hyperborean Sea be- tween a and b appears even and level, although through a Telefcope that Sea looks but like a great Lake or Marfh. So do the Parts of the Medt- terraneayi about d, from h to /, except when they are interrupted by Rocks or Land, as they are at h^ gb^ and c. At the laft of which places, begins a ridge of Hills encompaffing the Northern Part of the Mediterrane- an^ which makes a pretty fliew in the Telefcope. And now confidering how ac- complifticd the Moon, and all the o- d 3 ther liv A Plurality of Worlds. ther Planets are for Habitation, how folemn an Apparatus is in them for this fervice : and confidcring alfb that the(e Accoutrements relate to their refpedtive Planets only, and in all probability are of little or no ufe to our Earth ^ with great reafon therefore the Maintainers of the new Syfteme conclude thofe Planets, yea ail the Planets of the Sun and of the Fixt Stars alfo , to be habitable Worlds y Places, as accommodated for Habitation, fo ftocked with pro- per Inhabitants. But now the next Queftion com- monly put is, V/hat Creatures are they inhabited with? But this is a difficulty not to be refolved without a Revelation, or far better Inftru- ments than the World hath hither- to been acquainted with. But if the Reader fluould have a mind to amufe himfelf with probable GuefTes about the Furniture of the Planets of our Solar ^i /y . yi7 ^/.^.f-v ^4 75^^ Mi., afy ^^t> A Plurality of Worlds, Iv Solar Syftcme, what Countries 'tis probable are there, what Vegetables are produced , what Minerals and Metals are afforded^ what Animals live there, what Parts, Faculties and Endowments they have, with much more to the fame purpofe ,• he may find a pleafant entertainment enough in the great Mr. Chr'tflian Huy gens' s Cofinotheoros and fome other Authors that have written on the Subjed:. To which I fhall refer him, rather than give either him or my felf any farther trouble about thefe matters, which are merely conje^iural. Thus having, for the fake of the unfkilful Reader, given an account of the three Syjiemes principally con- cerned in the following Book, and having alfo, for the fake of the Doubt- ing Reader, infifted more largely than ordinary upon the two laft of thofe Syftemes, little remaineth for the putting an end to this long Pre- d 4 face, Ivi The CoHclufion, face, but to make my Excufe (if it needs any ) for affigning the Dia- meters and Diftances of the Heaven- ly Bodies in EngUfh Miles, rather than other larger Meafures, which would perhaps have come nearer the • truth. But this was alfo for the fake of fach as are not very converfant in Aftronomical Matters and Dimen- fions : who can better underftand you, when you fay, It is fo many Miles, than fo many Degrees, Mi- nutes, or Seconds, or Semidiameters of the Earth, or the other Planets. And now for a Conclufion, I fliall only intreat all my Readers to join with me in their earnefl: Prayers, that as this Work is defigned for the good of Mankind, particularly for the Convidion of Infidels and Irreligious, for the Promotion of the Fear and Honour of GOD, and the cultiva- ting of true Religion, fo it may have its defired Effed:.

ALTHOUGH the Number of the Erratick and Fixt Hea- venly Bodies we fee are fufficient to fet forth the Exiftence and Praifes of their great CREATOR, yet there is one thing more that I cannot eafi-* ly pafs over (though it hath only high Probabilities for it) becaufe it gives us a far more noble and agree- able Idea of the Creation, than the World was ever, that we know of^ acquainted with before ; and that is^ That the belt and mod learned mo- dern Aftronomers do generally fup- pofe the great multitude of Fixt Stars we fee^ or imagine to be in the Uni- D verfe. 34 "^^^ Fixt Stars Book If. verfe, to be fo many Suns^ and each of them encompafTed with a Syfteme oi Planets Uke our Sun. And that the Fixt Stars are Sum^ or of much the fame Nature as ot?r Sun, there is great rcafon to con- clude, 1. Because they are Bodies no left immenfe (as I have faid) than the Sun, but only diminiflied in ap- pearance, by their prodigious diftan- ees from us. 2. Because they (hine by their own native Light, not by any bor- rowed from the Sun. For fo great are their diftances from the Sun, and from us alfo, that it is not poffible their Light fhould be received from the Sun, and reflected to us, as that of the Moon and other Planets is. And withal, fo briik and vivid is their Light, and fo very fmall their apparent Diameters, when diverted of their glaring Rays, and made to have Chap. 2. fo mayiy Planets, 3^ have their true appearance through our Telefcopes, that no queftion is to be made, but that they ihine by their own innate Light, as our Sua doth. And if the Fixt Stars are fo many Suns, certainly they minifter to fome grand Ufes in the Univerfe, far a- bove what hath ufiially been attri- buted unto them. And what more probable Ufes, than to perform the Office of {o many Suns ? that is, to enlighten and warm as many Syftemes of Planets j after the manner as our Sun doth the Erraticks encompafling it. And that this is the Ufe and Office of the Fixt Stars is probable, I. Because this is a far more probable and fuitable ufe for fo ma- ny Suns, fo many glorious Bodies, than to fay they were made only to enlighten and influence our leffer, and I may fay inferior. Globe ^ which another Moon or two, or one or D 2 t'^'o 36 Planets about Book 11. two of thofe very Suns it:t nearer to us, would have better done, than all the whole train of Heavenly Bo- dies now doth. But inftead of this, many of them, nay perhaps the greateft number of them are at fuch immenfe diftances (as fhall be fliewn under the next Head) that they are out of the reach of our naked eye. In which cafe, what ufe is it likely luch great numbers of fuch immenfe, unfeen, far diftant Bodies can be to our World, when there are fo many already of divers Magnitudes of thofe that fall under View, that (befides other much greater Ufes they may {erve unto in the Univcrfej do mini- fler to our help and comfort here upon Earth, in fiipplying the Abfence of the Sun and Moon by Night? 2. From the Parity, and con- ftant Uniformity obfervable in all God's Works, we have great Rea- fon to conclude that every Fixt Star hath Chap. 2. the Ftxt Stars, 37 hath a Syfteme of Planets, as well as the Sun. For it is certain that the Sun is a Fixt Star to the Fixt Stars, as they are to the Sun. And in this cafe, if (as the juftly renowned Mr. Chrijitan (a) Hwygem argues) we Jhould imagwe our/elves to be placed fomewhere in the Heavenly Regions^ as far from the Sun as from the Ftxt Stars y we fhould then perceive no dif- ference between the one or the other* For it would be very unlikely that ive fhould fee any of the Solar Planets^ either by reafon of the diminiPotng of their Lights or becaufe their Orbs would fink into the fame lucid Point with that of the Sun, Being then fo placed^ we fhould imagine all thefe Stars [both Sun and Fixt Stars] to be much of the fame Nature and Kind ,• and from a view of any one of them nearer to us than the re/ly we Jhould (a) CofinQtheoros, /. 135. D J make 38 Modern S'^jieme of Book II. make our judgment of them all. And now hemg^ faith he, hy the favour of God, admitted fo near one of them^ namely the Sun^ as to fee fix leffer Globes revolving round about him^ and other Secondary ones revolving round feme of them : why ought we not to have the fame judgment of the refi of thofe Suns, as of this, and think it al- together probable that this is not the only Star of all the number that is en- compaffed with fuch a train ^ or in a- ny refpecl excels the refi ? Neither al^ fo that this Star alone revolves round its own Axis, but rather that all the refi have fomewhat of the fame kind alfo. And fo that learned Peifon goes on in the further purfuit of his ingenious Argument. 3. Besides thofe ftrong probabi- lities, we have this farther to recom- mend thofe imaginations to us, that this account of the Univerfe is far more magnificent, worthy of, and becoming Chap. 2. the Umverfe beji, 3c) becoming the infinite CREATOR, than any other of the narrower Schemes. For here we have the Works of the Creation, not confined to the more fcanty Umits of the Orb^ or Arch of the Fixt Stars, or even the larger Space of the Primum Mohihy which the ancients fanfied were the utmoil: Bounds of the Univerfe, but they are extended to a far larger, as well as more probable, even an inde?* finite, Space ^ as was fet forth in the firft Book. Alfo in this Profped: of the Creation, as the Earth is difcard- ed from being the Center of the U- rsiverfe, fo neither do we make the Ufes and Offices of all the glorious Bodies of the Univerfe to center there- in; nay in Man alone, according to the old vulgar Opinion, that allthmgs were made for Man (h). But in this our Scheme we have a far more ex- (h) See PbyficQ-theol. p. 3. C.d. N. Jo D 4 tenfive^ 40 Modern S'^fieme hefi.

Chap. III. Of New Stars. BESIDES the Planets of our Solar Syfteme, and the wonderful number of Fixt Stars, there are feme others, which are called New Stars^ which fometimes appear and difap- pear in divers Parts of the Heavens, and will defetve a place here.. SOMR 4i Of New Stars. Book II. Some of thefe New Stars have been taken notice of as early as Hip- parchus's tirDCj^ho/eemg/uch a New- Star^ and doubting whether it often happened^ and whether the Stars we take to he Fixt vjere fo or no ^ he therefore (as (d) Pl'my tells usj fet upon numbering the Stars for pofie- rity ^ a difficult Task^ he faith, even for a God: and hy proper Inflru- ments he marfloalled them in fuch or- der^ that their Places and Magni- tudes might be known : by which means it might be eafily found, not only whe- ther they decayed and perijhedy or were again renewed] but alfo whe- ther any of them changed their places y or had any Motion, as alfo whether they increafed or de ere a fed.

O F thefe New Stars^ there is rea- foij to imagine there may be many, by reafon they are not confined to any one part of the Heavens, but ap- pear and difappear in divers Conftel- lations, and divers parts of thofe Conftellations, as in CaJ/iopeia^ the Swan^ the Great Bear, Andromeday Eridanus, the Whale , the Ship, and divers other parts of the Heavens. (f) In the Mifcellanea Berolincnjta , p. 210, Mr. Kirch faith, he, for fome time, fought this Star in vain, but at laft on -^%r Auguft 1687. he found it with the help of an 8 Foo: Tube, but very fmall, and that it grew bigger and bigger, fo as on OEiober 1^. to be feen with the naked Eye, until having arrived to its greatefl Magni- tude, it again became lefs and lefs, and at lail invifible even in a Telefcope. By frequent Ob- fervations he difcovered its Motion to be very re- gwlar, and its Period to be 404 4- days. What chap. 3. Of New Stars. 4^ What thefe New Stars are, is hard to determine. Meteors they can- not be, becaufe they are of a long con- tinuance, and much too far off, for Bodies that emir fo little light as Me- teors do, to be feen by us. And as for other Opinions about them, they are too many, and too frivolous (fome of them) to be named (g)^ ex- cept one or two of the moft probable. Among which, one is of fome that think they may be fuch Stars as have one fide darker than the other, as one of Saturn's Satellites is fuppofed to have, and fo appear only when the bright fide is turned towards us, and difappear as the darker takes place. Some think they may be Fixt Stars that expire in Light and Vapours (h) (g) If the Reader hath a mind to fee a va- riety of thefe Opinions, he may find them large- ly enough handled in Riccioli's Ahnagefl.ubiftipvct C.17. (h) This is what Sir Ifiac Ne-joton furmifes in his Princif. £.5. Prop. ^2, and 4(5 Of New Stars, Book IL and arc again rekipdlcd, and recruit- ed by the Accefs of Comets. Others take them to be Comets themfelves. But if I may be admitted tofpeak what was formerly my own opinion, I ra- ther took them to be Errattcks of fome kind or other 5 and that for thefe Reafons : 1. From fome of them, as I thought^ feeming to change their Places, and appearing fometimes farther off, and fometimes nearer un- to other Stars: as 1 have faid in the Preface, /?. 45. 2. From that Increafe and De- creafe of their Light and Magnitudes which is conftantly obferved in them ; they being at firfi: obfcure, and hard- ly difcernible, but by degrees grow- ing brighter and brighter, till fome of them equal the light of Venus -^ and others the light of the Fixt Stars, of the Firft, Second, and Third Mag- nitudes: and then again as gradually groV chap. 3. Of New Stars, 47 grow lefs and lefs till they utterly difappear. 3. From their Periodical motion and return after a certain time. This indeed hath not been fo carefully and judicioufly taken notice of as it deferves, or fo as to bring their Pe- riods under certain determinations; but yet in fome of Hevehus's and CaJJini's obfervations, it hath been difcovered that fome of the fame Stars have returned, as particularly that in the Whale's Neck^ and that which now appears in the Swan's Neck, which as 1 juft before (pag, 44.^ faid, hath a Period of 404^ days, ac- cording to Mr. Kirch's obfervations. These were my reafons for fuf- pedting thofe New Stars to be Erra^ ticks, rather than Fixt Stars either re- cruitedjOr having dark and light fides. But the grand Difficulty is, what kind of Erraticks they are, whether Wandering Sunsy or Planets (like ours) of 48 Of New Stars. Book II. of other Syfteme^^? That they fhould be Wandering Sum^ w fomewhat odd to aflert ; and of what ufe they fhould be, is hard to imagine, fince there is nothing of this kind in the Uni- verfe, that we know of, that may aflift pur imagination. And as to the latter opinion, I confcfs I have been much enclined to fu(pe(5t that they might be Planets revolving round fiich Suns, as caft a much fiercer and more vigorous Light than our Sun doth ; and that ihefe their Planets might be more denfe than ours, and have Surfaces more ftrongly reflecting light, and perhaps be much larger too. But notwithftanding that Planetary Refle^ &ed Light may be fent to very great diftanccs by thcfe means, yet with- out extravagant Suppofitions of this nature, it liiay be doubted whether it would reach us, fo far off as the Fixt Stars are. And befides this, another chap. 3. Of Neiv Stars. ^9 another doubt is, That altho' there are divers Stars near thofe New Stars, of greater Magnitudes than any of thofe New Stars are, which I ever yet have had the fortune to fecj yet I can fcarce think them big enough, to conclude them to be the Suns a- bout which thofe New Stars (if Pla- nets) move. And therefore beinpr Imcertain what to determine in (o in- tricate a matter, I fiiall leave it to future better Obferv^tions (whicia the late long dark Weather hath hinder- ed me in the profecution of) which 1 hope may afford us fo good iighr^ as may lead us into a much greater knowledge of thofe rare Phxno- inena. But whatever thofe New Stars are, they are a farther Demonftra- tion of GOD's Power and Glory: and that there are many more of the grand V/orks of the Creation than what our Eyes behold at all^ or that E we JO Of New Stan, Book II. we have only now and then a glimpfe of. But if they are Planets of other Syftemes, fome of thofe Erraticks re- volving round fome of the Fixt Stars, then do they lay open a ftill more glorious Scene of GOD's Works, and give us fuch a reprefentation of the ftate of the Univerfe, that the World never dreamt of before, and that even Angels themfelves may be amazed at the fight of. BOOK ,rTrjc.xcs) BOOK III. THE DUE SITUATION O F T H E Heavenly Bodies. Chap. I. O/^ f Z?^ due as well as great DISTANCE of the Hea^ venly Bodies. H A V E before takeri notice of the immenfe Diftance of the Heaven- ly Bodies, that it is (uch as makes thofe vaft Bo- dies the Fixt Stars (no lefs in all pro- E % bability, ^iThe due Dtfiance of, 8cc. Book III. bability, as I faid, than the Sun it fclf) to degenerate into fo many Points, yea to efcape our eyej nay more than this, that it caufeth even our own Great Orb which our Earth defcribes about the Sun^ to fink in- to almofl a Point, or at lead a Cir- cle of but a few Seconds Diame- ter. I lliall therefore fay no more on that matter. But that which I fhall Tpeak of in this Book, is the due proportion of the Diftances of the Heavenly Bodies, that they are not fee at random, like a W^ork of Chance, but placed regularly, and in due order, according to the bcft me- thods of Proportion and Contrivance. Which will be manifeft from the fol- lowing Chapters, which will fliew that tlie Diftance is fuch, that none of the Globes interfere with one ano- ther: but inftead of that, are indue and the mofl: nice^ commodious Pro- portion. C H A ?♦ Chap. 2, Globes interfere not. j^ C H A P. IL That none of the GLOBES of the Univerfe interfere. HA D the Univerfe been the Work of Chance, or any thing but of a wife Archited, there would have been a great many blun- ders and inconveniencies in the Situa- tion of fuch a prodigious number of immenfe Globes, as the Univerfe doth contain. Some would have been too near, fome too far off, fome would have met with, knock'd and ftop'd one the other, and fome would have fo interfer'd as to have incommo- ded the other, fome way or other. But inftead of this, every Globe throughout the whole Creation is, ^s far as it is poffible for us to obferve, E 3 fee j4 None of the Book III. fet at fuch a due Diftance, as not only to avoid all violent Concourfes, but alfo fo as not to eclipfe or {hade one the other, wherever it may be prejudicial, or indeed not ufeful and convenient, or fo as to hinder one anothers kindly Influences, or to pre- judice one another by noxious ones. This is very manifeft in our own Sy- fteme of the Sun ^ and becaufe we fee it not otherwife, we may conclude it to be fo in all ,- unlefs we ihould make fome exception for what is fuf- pe6ted (and indeed only fufpeded) of Comets^ which in their approaches towards the Earth, are imagined to caufe Difeafes, Famines, and other fuch like Judgments of God. But this is only Surmife, and what befals the world at other times, without the vifible approach of any Comet. But however, fuppofing that as Comets move in Orbs very different from thofe of the other Heavenly Bodies, fo chap. 2. Globes interfere, yj fo their Effects and Inflaences may be as different j yet this may be, and no doubt is (becaufe it may be pro- ved) with the concurrence, and by the appointment of the Divine Pro- vidence ,♦ who, as Governour of the World, might make fuch noxious Globes to execute his Juftice, by af- frighting and chaftifing finful Men, at their approaches to the Earth ,• and not only fo, but (as fome have ima- gined) to be the place of their Habi- tation and Torment after death. But fuppofing it to be fo, yet herein is a kind Providence manifefted. That their Returns to the Earth are but feldom (a)^ and their Stays fhort, and that (a) There having of late been great Expefta- tions among fome, of a Comet appearing this year 171 8, it may gratify their curiofity to take notice, in this place, of the three Comets, whofe Periods we imagine, are difcovered, by the great Sagacity and Application of our modern Aflro- nomers. The Revolution of the Firfi of the Three, is fuppofed to be performed in 75 years; P ^ and ^6 No^woftheG/ohs, Sec, Book 111, that they take up many years in paf- fing the reft of their Orbs. And now whether we confider the due Situation of the greateft part of the Heavenly Bodies, whereby neither they, nor their influences do interfere^ or the more unufiial Pofi- tion and Motion of Comets, ftill it appears that a wife and careful Ar- chited was the Contriver and Orde- rer of it all : efpecially if we joia what follows in the next Chapter. and to have been the fame Co?H^t that appeared in the year 16S2. The Second is fuppofed to be the Comet that was feen in the year i(55i, and to revolve round in izp years. And the 'Third is imagined to be that Com?t which appeared in 1680 and 168 1, whofe Period is 575 years. And according to Mr. Whijlons Determinations, the Firfl of thefe three Comets will again appear if^ the year 1758, the^'^row^in 1789, and the T^nrd and laft not till about the year 3255. C H A ^, chap. J. The Due D'tfiance^dcc. 57 Chap. IIL Of the nice Proportions of the Diftances of the Hea- venly Bodies. As it is one great demon ftration of the ingenuity and Ikill of an Archited to give due Proportions to his Work j fo we find this to be abundantly manifeft in all the Bodies of the Univerfe that fall under our cognizance : among which we may difcern a curious Order, and that due and nice Proportions are ftridly obferved in their Situation. How the Fixt Stars are fituated in refped: to one another, is impofli- ble for us to determine at fuch pro- digious Diftances as they are from psj but they look to us, who can have 58 Due Diflance of Book III. have no regular profped of their Po- fitions, as if placed without any Or- der : like as we (hould judge of an Army of orderly, well difciplined Soldiers, at a diftance, which would appear to us in a confufed manner, until we came near and had a regu- lar profped: of them, which we {hould then find to itand well in rank and file. So doubdefs, if we could have an advantagious profpe6t of the Fixt Stars, we fliould find them very commodioufly, and well fet in the Firmament in regard of one ano- ther. And this we have great rea- fon to conclude from the Rules of Parity, from that conftant Harmony, and Similitude obfervable among all the works of the Creation, which fall under our cognizance : particu- larly this is evident in this Region of the Univerfe, to which we belong, and which we have a better Profped: of, and can furvey with our Inftru- ments. Chap. 3. the Heavenly Bodies, 59 ments, I mean the Syfteme of the Sun. In this we find every Body- placed in good order, and at due di- ftance, according even to the niceft Rules of Proportion. For the evidion of this matter, let us (according to the mod received and rational Hypothefis) fuppofe the Sun placed in the Center, to influ- ence all his Planets with Light and Heat. Then follow the feveral Pla- nets, furrounding him, not one here, and another there, at all adventures, in a rude manner, like a Work of Chance^ but at due Diftances from the Sun ^ at proper Diflances from one another j and in fuch well ad- jufted proportion of their Velocities and Gravities, as makes the Squares of their Revolutions in proportion to the Cubes of their Diftances. And this is what is difcernible in the whole Solar Syfteme, not only in the Primary Planets that revolve round the 6o Due Proportion of Book III, the Sun, but in the Secondary Pla^ nets alfo, that revolve round them. Thus it manifeftly is in tlie Five Moons that accompany Saturn^ and the Four accompanying Jupiter. And a moft fagacious Contrivance this is, manifefting the Prefence, and Condudt of the CREATOR, in thus chufing this Proportion I fpake of, rather than any other. For fliould the power of Gravity (for inftance) have been fo conftituted, as to de- creafe in the Proportion of the Cubes (inftead of the Squares) of the Di- ftances reciprocally ,♦ although it might be poflible to adjuft a Velo- city, and 1 may add, a Diredion too, fo as to make Bodies defcribe perfed Circles, yet the leaft Excefs or Defed of Velocity, or the leaft Obliquity of the Diredion, would make them defcribe Spiral Curves, either afcending in infimtum, or elfe defcending to the Center. And fup- pofing chap. 3. the Solar Syfieme, 61 pofing the Orbs (in which thofe Bo- dies move, and which are fuppofed, as I faid, to be made in proportion of the Cubes) to be perfedly Circu- lar, the leaft adventitious Force, e- ven but of an Atom, abating or in- creafing the Velocity, or changing the Diredion, would bring on the a- forefaid Inconveniences. And if the great CREATOR and Contriver of the Univerfe hath thus wifely mo- delled , and cautioufly methodized this part, this Syfl:eme of it where we live, and behold the thing, no great doubt can be made but that he hath done the fame in the other Syftemes thereof alfo ; that every Syfteme is fet at a due Diftance from one the other, and every Body in each Syfteme at its due Diftance alfo from their Sun, or Fixt Star. And now who can refled upon thefe things, and not perceive and admire the Hand that adteth in them, ' the 6 1 CAczi^d'sConclufion, Book III. Contrivance and Power of an infi- nite Workman!

That all thofe vaft Globes of the Univerfe (hould have a Moti- on, muft of neccffity be from fome Being that had Power enough to put them in motion. For as LaBant'ms well argues, (aj There is indeed a pow^ er in the Stars^ (and the like may be faid of the reft of the Globes) of performing their Motions^ hut that is the Power of God^ who made and go* verm all things ^ not of the Stars them-* felves that are moved.

But allowing that it is poffible it might be fo, yet ftill we muft recur to fome Ftrfl Mover ^ fome Primary Agent^ who was able to fet that principal Mover into Motion : and then the cafe amounts to much the fame, and the Argument hath the fame force, whether we attribute the Motion of one, or all the feveral Globes to the Power of GOD.

But we fhall moreover find an infinitely Wife, as well as Almighty Power herein tranfading, by what follov/s m the oezt Chapter. p 4 Chap« 72 The Motions oj the Book IV. Chap.

I fhall liere fpecifie but two Examples, becaufe I {hall have oc- cafion to fay more of this matter hereafter. One is , That all the Planets fhould (when their Motions were impreft upon them) have their Pireftions or Tendencies given, not Chap. 2. Heavens regular, 73 in Lines tending from the Center to the Circumference, or very Oblique- ly, but Perpendicular to the Radii, The other is, That the Motions and Orbits of the Planets fhould not interfere with one another, but tend one and the fame way, from Weft to Eafl, and lie in Planes but little inclined to one another, or when inclined, that it fliould be very be- neficially fo, as I fliall hereafter fliew. Thefe and many other In- ftances, and in a word, that every Planet fhduld have as many, and va- rious Motions, and thofe as regular, and well contrived and ordered, as the World and its Inhabitants have occafion for, what could all this be but the Work-of a wife and kind, as well as omnipotent CREATOR, and ORDER ER of the World's Af- fairs ? A Work which is as plain a Signal of GOD, as that of a Clock, 01 other Machine is of Man. Thus Tully's ^4 Motions of the Book IV. Tully's Sto'tck (a) argues our prefent cafe from the Shepherd at Aciiuniy when from the top of an Hill, he happened firft to fee a Ship failing in the Sea, he was for a while in great amazement, and furprize, to fee fuch a moving inanimate Body, and could not fmagine of what a Nature it was poffible it fhould be^ until he perceived, by fome tokens, that it was made and managed by Man. So^ faith he, the Ph'dofophers ought to have done^ if haply they had any doubts at the firfl view of the World: afterivards when they fhould behold its determined and equal Motions^ and (ill things managed by eflablifhed or- ders, and with immutable conftancy ^ they ought then to underfland that •^here is not only fome Inhabtter in this heavenly, this divine Houfe, but alfo fome Ruler and Moderator, and in a (a) De Nat.

Thjs diurnal Rotation is vifible in many Chap. 3. of the Sun, 77 many of the Heavenly Globes, and highly probable in our own. In the Sun it is very manifeft from the equa- ble Motion of its Spots, which fome- times appear in its Difk, and have been obferved formerly by GaltUofaJ^ Schemer (h)y Tarcle (c)^ Mahperttus^ (a) Galilaus tells in the third Dialogue of his Syftem.

'Tranf.) may be (ctn at one view in Mr. Lowtljorp's Abridgments 1. 1, p. 274- Upon chap. 3. of the Sun, 79 upon its Poles: for we may perceive them to be perpetually (hifting their places from the Eaftern to the Weft- ern Limb of the Sun 5 and in thus doing, their daily Stages and Mo- tion exa(5tly correfpond to the Mo- tion of a Globe ^ that is, thofe Sta- ges are fhorter, and the Motion of the Spots feemingly flower towards the Sun's Limb, but near the Cen- ter of the Dilk, larger and fwifter ,• and all in exadt proportion to a dou- ble Line of Sines, or a Line of Sines on each Semidiameter of the Difk. And farther yet, thefe Solar Spots, as they manifeftly demon- ftratc the Sun to be a moving Globe, turning round once in fomewhat a- bove 2 J days, fo they manifeft them- felves to be fomething adhering un- to, or nigh the Sun's globous body, by means of the different appearance they have in the different parts and pt)fitions of the Sun i as in the mid- dle 8o Dturnal Motion Book IV. die of the Difk, if they are round, towards the Limb they become more and more oval or long, juft as fuch a like Spot on a common Globe would appear when it is turned fo as to be viewed by us fideways or going out of fight.

III. Of the Power and Ufefulnefs of Gravity to retain the Planets in their OrVits. OR a Conclufion of this fixth Book, 1 fhall take notice of one more remarkable benefit oi Gra^ vity^ which is grounded upon the fuppoficion of the truth of the New- tonian P hdofophy -^ which hath fogood Grounds, and great Reafon, I might fay Demonftrations on its fide, par- ticularly in this matter, that admit- ting of it here, we fliall difcover a- nother admirable Work of the Crea- tion, and that is, the preventing the Evagation of the Planets, and the accurate retaining them within the due Bounds of their Orbits. That this 4 I J4 ne Ufifulnefs Book VI. this is done by Gravity^ and that Gravity and Motion folve in the mod complete manner, all the Phse- nomcna of the Planetary Motions both Primary and Secondary, is a- bundantly made out by the wonder- ful Sagacity of the great Sir Ifaac Newton I as may be feen in his PriH- cipia. But before I come to the par- ticular agency of Gravity^ it will be necefTary to premife foraething con- cerning its Nature, and fome of its Properties, viz. That Gravity is not terminated at the Surface, but reaches to the very Center, and is extend- ed to immenfe diftances all round the Centers of all the Globes : By which means, the cceleftial Bodies are enabled to have Syftems of lef- fer Globes revolving about them. For had the Force of Gravity de-r termined at, or near the Surface (as it might have done, if intended only Chap. 3. of Gravity. ijj cnfy for the Confervation of the Globes) in this cafe, all the Bodies that were put in Motion, and that were to pafs at fome diftance from them, would move on in a ftrait, not curved line, and be loft in the great Abyfs of Space. But the all- wife CREATOR, harh, in his firft Production of Matter, beftowed up- on it fuch a Property, as that every Particle thereof hath a Tendency towards every other Partick. From whence it comes to pafs that every Body hath a Gravttaung Power ac- cording to the folid Content, or real Quantity of its Matter, and not according to its Superficies, or Ex- tenfion. And this Gravity of all Bodies is obferved , manifeftly to decreafe in proportion of the fquare of their Diftances reciprocally ,• that is, at twice their diftance the Force is but one fourth of what it was atafingle diftance • ijd The Properties Book VI, diftance j and but a ninth, at thrice the diftance, &"€. That this is fo, is abundantly proved by the lad commended Au- thor,- who by eftablifliing this one Principle in Philofophy, hath fully explain'd the Syfteme of the World, fo far as relates to us, and to all the reft of the Planets, that regard the Sun as a Center, both Primary and Secondary. What the Caufe of Gravity is, Sir Ifaac Newton doth not pretend to aiTign, his Defign being not to en- gage himfclf in framing Hypothefes^ but to explain the Pht^nomena by Experiments only, and to raife his noble Supcrftrudure upon them. And therefore, although the mat- ters of Fa6t, and the Final Caufes are evident, 1 will not venture to fay how it comes to pafs, that Bo- dies adl at fuch immenfc Diftances upon ane another j but chufc rather ^ to chap. 3 . of Gravity. lyt^ to acquiefce in adoring the Wifdom and Power of the GREAT AU- THOR of all things, who hath in- fpirited the Materials of which the World confifts, with fuch an adive quality, as ferves not only to pre- ferve the Globes themfelves entire, but to enable them to revolve about their luminous Center (from whence they have their Light and Heat) in Orbs that are the molt commodious, and alfo fixt and permanent. Having thus premifed what was neceflary for the underftanding the Nature and Properties of Gra- vity, I fliall proceed to confider its agency in the Planetary Motions. And here we have divers things j which plainly demonftrate thefe Mo- tions to be no matters of Chance^ but the Works of an infinitely Kindy as well as Omn'tpotsnt and Allvuife Agent. I HAVJg I 5 8 The Planets are retamedm B. VI. I HAV£ already in Book 4. Ch. 2^ taken notice, of the Motion of the Planets, being made, not in Lines tending from the Center to the Cir- cumference, or very oWiquely there- to, but acTofs, or nearly perpendi- cular to fhe Radii. Alfo that the Motions, and Orbits of the Planets, do not tend contrary ways^ or much interfere with one another. That therefore which 1 fhall fpeak of here^ concerning the Planetary Motions being the Work of God, will be on^- ]y fo far as Gravity is therein con- cerned. And I. It Wiis a very notable provifion to prevent the Evagation of the Pla- nets, and to keep them within their due and proper Bounds, to bridle and detain them with Gravity, as with (o many Reins and Bridles. For as the natural tendency of all imprell: Motion is in ftrait Lines, fo when Motion was given to the Pla- nets, dh.3-. t^heir own Or hs by Gravity , IJ9' nets, this Motion (alcho' as I faid it was artificially made, perpendicu- larly to the Radn^ yet) would car- ry them quite away in their Tan- gents, fo that they would never re- turn again. But being thus detain'd by Gravity, another admirable pro- vifion is that, 2. They are moved in Orbs : Which Orbs are formed of a Motion compounded of this Redilinear Impulfe, impreft upon th€ PUners, and the tendency of their Gravity to their Centers. In which Motion a third thing very re- markable is, That the Impulfe or Velocity which is imparted by the F'trji Mover to every Planet, and the Gravity of each Planet, are fo near- ly equal to what is required to make a Body defcribe a Circle, that the Orbits of the Planets are not very Eccentrical, but nearly Ciroilar. As is pfrrticularly remarkable in Ve- vasy and the E^etrth j and more e- fpecially i6o Of the Orbits Book VL fpecially in the whole Syfteme oiju- piter's Satellites. And an admirable Work this is. For ftiould the Velo- city of any Planet be double to what would make it move in a Circle^ the Planet would go away m infi- mtiim^ without ever returning again in any Orb whatfoever. Or fliould one half of the Velocity be taken away, the Planet would defcend ob- liquely towards the Sun, until it be- came four times nearer the Sun than before 5 and then afcend again to its former place, defcribing a very ec- centrical Orb. And by afcending and defcending alternately, it would be heated fixteen times more at one time than another. Which uneven Heat would make the Planet unfit for Habitation. And the fame thing would happen, if the determination of its Motion fliould be altered, fo as to become very oblique to the RadiiiSy drawn from the Planet to the SuUo Chap. 3 . of the Planets, i ^ k Sun. But thefe things being accu- rately adjufted, and contempered3 make the whole Syfteme to be a work of incomparable Convenience and Beauty ; a Work the beft con- trived for the Benefit of the World's Inhabitants, and to fet forth the Curiofity and Skill of the infinite Workman. It h manifeft therefore that the Syfteme of the Planets is not to be reckoned a matter of Chance y or a thing owing to a NeceJJity of Nature^ but the Work of a kind and wife A- gent. And that this is fo, will be farther manifeft from the cafe of Comets^ whofe Motions, Directions and Orbs being utterly different from thofe of the Planets, demonftrate the Planetary Syfterne to have been modelled by Counfel^ and not by a Necefjity of Nature, or left to Chance, For as for the Motion of Comets^ it is fo far from being always the fame M way;. 6i Of Comets. Book VI. way, that they move fometimes con- trary to one another. And as for their Planes and Diredions, they He every way. And as for their Orbs, they are exceedingly eccentrical. And by the bye, this Eccentricity is an admirable Contrivance of the CREATOR, to prevent the Co- mets from difturbing either the Pla- nets, or one another, by their mu- tual Attractions. For by this means, they have a large and fufficient room to revolve in ; and by afcending to very great heights, above the Syfteme of the Planets, and fpending almoft all their time in the remote regions of the Univerfe, at vaft Diftanccs both from the Planets, and from one another, they do not incom- mode either the Planets, or them- felves; as otherwife they would have done, fliould they have moved in the fame Plane with the Planets, For had they done fo, they would have chap. 3. Of Comets. 163 have been apt fomctimes to have come too near the Planets, and have difturb'd their Motions, and perhaps have daflied upon them al- fo. But all thcTe Circumftances are fo well adjufted, and fo wifely re- gulated by the Divine Providence, that the Syfteme could not have been better contrived, either for Conve- nience or Beauty. And now upon this highly pro- bable, I may fay phyfically certain.

Of the Light and Heat of the Fixt Stars and Sum S Light and Heat are two of the moft ufeful things in the Univerfe, fo the infinitely wife and kind CREATOR hath made an excellent Provifion for thefe things^, in all pro- bability, Chap. 1. Ltghtof the Ftxt Stars, 167 bability, for every Globe throughout the Univerfe, but: particularly for thofe of our own Syfteme. For it is very manifeft, that every Globe we fee, doth (liine with its own native, or with borrowed Light. Even all thofe immenfe Bodies at the greateft diftance from us , the Fixt Stars, which I have before faid, are proba- bly fo many Suns, it is Light they manifeftly dart as far as to our fo diftant Globe, as well as what they emit for the enlightening, warming, and cherifhing their own refpedive Planets. But I (hall forbear to launch out into thofe conjedural matters, and fliall come nearer home, into our owtx Syfteme, where we have enough to entertain our Eye, to captivate our Thoughts, and to excite our high- eft admiration of thefe magnificent works of God; whether we furvey the great Fountain it felf of our M 4 Ligf^? i68 7he Light and Heat BookViL Light and Hear, the Sun ^ its due Pofition, and its wonderful ufe to its Planets j and the incomparable Provifions that are made to fupply its abfence and greater diftances from them.

Thus (a) The famous Burning-Concave at Lyom, of 30 Inches Diameter, and others in France and Germany, of greater breadths, have been celebra- ted for their Feats in burning, calcining and vi- trifying, both metallick and other Bodies. But I queftion whether any of them have come up to the Burning Inftrument contrived by, and rpade fqr Sir Jfaac Neivton, and by him preient- ed to the Royal-Society.

By which means the Heat is fo increafed, as in a furprizing Manner to perform the Feats here mentioned, and many others furpafling them.

But what their Power was, he did not fee. Chap. Chap. 2. The due Po fit ion ^^c, 171 Chap. II. Of the due Vofition and Di- flance of the Sun and its Planets. As the infinite Power and Wis- dom of God appears in the appointment and make of the Sun, according to the preceding Chapter; fo in this I (hall demonftrate the fame, from the due Pofition of the Sun among his Planets, and his due Diftance from each of them. Now here we may take it for granted, that the Sun is the Fountain of the Light and Heat of all the Planets, not only of the Earth, but of the other Planets, that move ei- ther about the Sun, or the Earth. But whether the Sun be placed in the Center 17 '^ Earth and Sun at Book VII. Center of its Syfteme, or the Earth be (oy is of no great confequence here to enquire. But I have all a- long fuppofed the former to be the mod: probable Hypothefis, and it feems to be ftill more fo, from the confideration we are now upon, concerning the community of its Light and Heat to all the Planets. For fmce it is manifefl:, that what Light and Heat the Planets have, they receive from the Sun, it is far more likely that this their Fountain of Light, and Heat, is placed in the common Center of them, and that they move round about it, rather than it about them. But be it fo, or not fo, it is how- ever very certain, that all the Pla- nets are placed at fuch a due, and pro- per Diftance, from the Sun, that they receive the beneficial Rays thereof, in a due manner and proportion. There is no great reafon to double of chap. 2. a due dtflance> 173 of this, among the Planets that are at greater or leffer Diftances from the Sun than we, becaufe we find {^o noble and folemn an Apparatus, an- fwerable to their Diftances from the Sun, which I intend to fpeak of hereafter. But as for our own ter- raqueous Globe, we have fufBcienc fignals of the great care and counfel, that have been ufed in the due Pofi- tion, and Diftance thereof from the Sun. For as to its Pofition to the Sun, I have heretofore fhewn, thac by the Inclination of its Axis, and its Diurnal and Periodical Revolu- tions, all parts have a due iliare of Light and Heat. And as for its Diftance, it is fuch, as not only pre- vents the Danger of its interfering with the other Globes, as I have formerly obferved, but alfo it is du- ly adjufted to the Denfity of the Earth and Waters, and to the Make and Temper of our Bodies, and of al! 174 Benefits of the BookVlI. all other things here below. Had we been much nearer the San, our World would have been burnt up, and wafted ,• the Waters, in the firft place, would have all been turned into va- pours, and dried up,- Vegetation have foon ceafed, and all things would have foon been wafted, if not burnt and confumed. Or had we been not at fo very great a diftance, but only a little nearer the Sun, than now we are, as fuppofe a few thou- fands of Miles, ftill the Heat would be as the fquare of the (a) diftance- and confequently too great, if not for the Polar, yet for the Equato- rial parts. And on the contrary, had we been fet at a greater diftance from the Sun, fo would the Sun's Heat have been abated, in propor- tion to the fquare of that diftance. And in this cafe, if the diftance (a) Newton. Princi^. p. j^66, had chap. 2. Surfs due dtjlance, 17 j had been very great, we and all things mud have been perpetually frozen up; or if it had been not fo great, the world would have fuffer- ed by cold, the Polar at leaft, if the ^Equatorial parts lliould efcape. And in this cafe, when our Globe fhould thus be parched up with ever- lafting Heat, or be everlaftingly frozen with exceflive cold; inftead of an habitable, pleafant, and com- fortable world , it muft become a Defart, a place of irkfomnefs, mi- fery, and everlafting punifhment. But the great CREATOR having fo wifely, and indulgently, ordered the diftance between the Earth and Sun, the Sun's Light and Heat are incomparably accommodated to the ftate and temper of all things here below, and our World is well fitted for Habitation, well provided with every thing that may minifter to the fupport, the comfort, and pleafure of 176 Benefits of the Book VIL of its Inhabitants. By thofe indul- gent Rays, all things are enHghten- ed, and we, and all the reft of the Animal Kingdom, are enabled to difpatch our Bufinefs^ to feek and provide our Food, and to pafs from place to place, as our occafions or pleafure lead us.

Thus it is manifeft how wifely and indulgently the great CREA- TOR hath provided for the good of our Planet, by fo critically adjufting its Pofuion to, and its Diftance from the Sun, to the ftate and temper of it, and all things thereon.

And firft as to the Earth, Of (ucb abfolute neceflity is Light (not to mention Heat) that our World could not well be in the lead utterly with- out it, becaufe during utter, abfolute Darknefs (befides the great inconve- niences it might bring to Vegetables^ Minerals, and every other fuch like part of the Creation, befides this I N 2 fay) i8o The Necejfity of Light, BookVlI. fay) it would certainly put Animals under an abfoluce incapacity of per- forming their moft neceflary Bufi- cefs, and adling in that office which the divine Providence hath appoint- ed them, although of greateft ufe to themfelves, or the reft of the World.

But whatever influences the Moon may have upon things here below, whatever her Concern may be in any tranfadtion of Nature, or any other office of the Creation, it is however very certain that her Light, EclipfeSj Alonthly Revolutions, and Latitude^ or Vagations towards pur Poles^ are of great ufe to us.

As to the Eclipfes, whether of Sun or Moon, they have their excel- lent ufes too. The Aftronomer ap- plies them to confiderable fervices in his way ^ and the Geographer makes them no lefs ufeful in his; the Chronologer is enabled by them to amend his accounts of time, even of the moft ancient days, and fo (c) Ferunt Luna fxm'meum ac moUe Sidusy at que nofiurnumf folvere huntorenty ^ trahere, non ai^ ferre.

And laftly as to the Lunar La- titude y or ProgreiTes towards our Poles, befides the ufe hereof to the preventing the two frequent EcHpfes of the Sun and Moon, thofe Vaga- tions are of great ufe to the Polar parts of the World, in affording them a longer, as alfo a ftronger and better light, than if the Rays fell more ..oblique: which muft needs be a very great comfort, and of won- derful fervice to the Inhabitants of thole forlorn parts, in their long and tedious Nights, of fome Days, yea feme Months length : to men, to enable them to difpatch fuch of their Affairs at are of perpetual and con- ftant neceffity ; and to other Ani- mals of the Air, Land, or Waters, to enable them with greater ea(e, and pleafure, to get their Food, and pais where their plealure leads them. Thus chap. 4- Earth and Moon ^ dec, 189 Thus the great CREATOR hath made the Moon to be of ad- mirable u(e to our Earth. And (b wifciy hath he contrived his Works, that they are mutually ferviceable to one another, fo that what good fer- vices one doth, the other as readily returneth again. Thus as the Moon is a Moon to us, fo the Earth is, with great reafon concluded by the Philofophers, to be a Moon to the Moon ,• not indeed a Secondary Pla- net moving periodically about her, but fuch a Planet, as reflects the Light of the Sun to her, and per- haps makes fuch like returns of In- flux, as I faid the Earth receives from her. For it is not to be doubted, if the Earth refleds light, and gra- vitates to the Moon, as well as the Moon to the Earth (which is highly probable) but that there is a mutual intercourfe, and return of their Influ- ences, and good Oiffices. And this is ipo Earth and Moon ^ dec. Book VII. is ftill more probable from the like- nefs difcernible between the Earth and the Moon^ which is a ftrong prefumption that the Moon may have the fame occafions for the Earth, as the Earth for her. For that {he is an opake body, and that her (iirface is covered in fome mea- lure with Hills and Valleys, is ma- nifeft beyond all doubt to our Eye (d) as I before faid : and that (he hath an Atmofphere is what hath been not long fince (e) difcovered : and that there are large Oceans and Collediions of Water is what I have before made probable (f). And therefore agreeing thus in Conftitu- tion and Make, their Occafions for, and Influences upon each other are in all probability mutual, and much the fame. (d) See Book 5. Chap. 2. Note^.

And here we (liall find a no lefs admira- ble Scene of the great CPvEATOR's Care and Wifdom, than we difco- vered in the Earth and Moon. la Mars indeed, we can difcern a great fimilitude with the Earth, in its Opa- city and Spots^ but we have not yet O beea 194 Provifion for Light BookVIf. been able to perceive any attendance of Moons, as in the other fuperiour Planets j not fo much probably be- caufe there are none, but becaufe they are fmall, or they reflect a weak light, and are at a great di- ftance from us. And as for P'^enm and Mercury there may be no oc- cafion for any Attendants, by rea- fon of their proximity to the Sun, But in the two highefr, or more di- flant Planets, Jupiter and Saturn^ we have a very noble, and entertain- ing Scene of the CREATOR'S Glory. For whereas thofe two Planets are at a much greater diftance than any of the other Planets, from their Foun- tain of Light and Hent, the Sun ; and as confequently their Heat and Light are abated in proportion to the fquare of their Diftances ; fo to make them amends, they are fur- rounded with a more grand Pvctinue of Secondary Planets ^ or Moons j Jupiter Chap.

But there are divers provided. One is by the frequent Rotations of Ju- piter round his own Axis j which be^ ing performed in lefs than 10 hours, it comes to pafs, that what is want- ing in the flrength, and degree of Light and Heat, is compenfated by the frequent Returns thereof The other Remedy is by the In- creafe of the number of Moons, about Jupiter^ who is attended (as I faid) with four, as we who are nearer the Sun, are with one. Concerning which thefe four things are remark- able, I. TMf-IF> Chap. (5. Juptter"^ Moom, 199 1. Their Bulk, which in all pro- bability, is not in any of them iefs than our Earth, as the mod inge- nious Mr. Huygens concludes f^^^from their (hade upon Jupiter's difk. By which partly it is that, 2. They refled fo ftrong, brijfk, and vivid a Light, as appears very iiluftrious, and entertaining, even to us at fo great a diftance from it: which cannot but be very pleafing and comfortable to that Planet: be- fides the no Iefs beneficial and friend- ly Influences conveyed therewith at the fame time. 3. Their due Diftances from Ju- piter^ and from one another^ and their agreeable periodick Revoluti- ons, which I have formerly obfer- ved (d) to be in the moll: exadt ma- thematical proportions. By the firft (h) Cofmotheor. p. loi. (d) Book 4. Chap. 4. O 4 of 200 "Jupttefs Moons, BookVII. of thefe, thofe Satellites efcape all difagreeable Concourfes, and violent Oppofitions, and, in the moft kind- ly manner, fend their Influx to the Planet they wait upon: and by the latter, they are perpetually carrying about their Light, and other benefits from place to place. For by the motion of thclnnermoft, round once in lefs than two days,- of the next ixi about 3 4 days,- of the Third in fomewhat above a week ^ and of the Outermoft in near 17 days : by thefe means, I fay, it happens very feldom that any part of Jupiter is at any time without the prefence and atten- dance of one or more of thofe Sa- tellites j but one is vifiting one parr, whilfl: another is attending another, and another another part, and Ju- piter himfeif making fpeedy Returns and Revolutions all the while. 4. The laft thing remarkable is tiae Latitudes of Jup'tter'% Moons, or their chap. 6. Jup'tter's Moons, 201 their progreffes towards his Poles, which are in a due proportion to their Diftances and Periods : as 1 have before (hewn, Book^, Ch, 5. And as the Latitudes of thefe Sa- telHtes differ, according to their Di- ftances and Periods j fo another re- markable thing therein, is, that they fhifc their Latitudes, in longer or lliorter times, according as their La- titudes, or Vagations towards the Polar Parts oi Jupiter^ are greater or leffer. By which means, fome are making their progreffes towards Ju- pher's Poles one way, whilft fome are wandering the other way, and fome are flaying there a longer time, and fome a lelfer and leffer time. By which quadruple Variety of La- titudes, and perpetual changes of it, it comes to pafs, that thofe large trads cowards the Polar Parts of that vaft Planet, have their due fliare in jhe light, and kindly fervices, of its four 201 Saturn's Satellites, Book VII. four Moons, and are fddom or ne- ver deprived of them.

H AVING ktn the admirable provifion made for the x^- xncdyingjup/ter's great diftance from the Sun y let us, in the laft place take a view of Saturn; which is above 200 millions of Erigli/h miles farther from the Sun than Jupiter^ and near 700 millions of miles farther than is our Earth. And here our Glaffes, as imperfect as they are, have difcover- ed fo furprizing an Apparatus, that mufl: needs ftrike every one that views it with v/ondcr and amazement. For, C h ap . 7 . Saturn's Satellites, 203 For, in the firft place, inftead of four Satellites or Moons, as Jupiter hath, Saturn hath five, and pro- bably more. Three of thefe I my felf have feen with Mr. Huygens's 1 2(5 foot Glafs; but for want of a Pole of fufficient height to mount the Glafs high enough, I am not fiire I have feen any more. And befides thofe Five, which others have feen, there is great reafon to conclude there is a Sixth lying be- tween the two Outermoft, there be- ing a larger fpace between them than is in proportion to what is found amongft the reft. And it is not improbable but that there are o- thers alfo lying beyond the Fifth, or Outermoft, but become invifible at fo great a diftance from us, by means of fome obfcurity, fuch as is obferva- ble in the Outermoft it felf, which is never to be feen by us, but in the weftern 204 7he Bulk of Book VII. weftern part of its Orbit, as Mr. Hu'^' gem well obferves (a). These Satellites we may reafo- nably conclude to be of a prodigious bulk, for the rcfleding of Light, and for their other miniftrations to Saturn^ becaufe otherwife they could not be feen at fo great a diftance as the Earth ; and particularly one of them (h) is of that magnitude, and (.i) The reafon why Saturn^ s fifth Satellite ap- pears not on the Eaftern, but Weftern part of its Orbit, Mr, Hiiygens very fagacioufly (like himfclf) conjedures to be, becaufe this Satellite^ as the Moon doth to the Earth, always turns one and the fame Side to Saturn, and becaufe this Sa- tellite hath, he imagines, only one part of its fur- face clear, and the greateft part obfcure, and not able to reflid fiifficient Light to us, there- fore all the time that obfcure part is turned to- wards us (which is whilft the Satellite is m the Eaftern parts of it's Orbit) it difappears: but in the Weftern part it appears, becaufe the bright Side lies towards us.

Concerning which thefe things are obfervable. I, The prodigious y/sd* of it, its great breadth and vaft compafs. This we may make a judgment of, by comparing it with Saturn himfelf. And fuppofing the Diameter of Sa- "^ turn io6 Dtmenfiom of BookVlI. turn to be as is before determined, 93451 EnglKh miles, the Diameter of his Ring will be 210265 fuch miles,and its breadth about if)ioo(c)^ an amazing Arch to an Eye placed in that Planet. 2.

See Hugen. Syft. Saturn, p. 70, As 4 2o8 Various /Jfpecls, Book VII. y. As the Periodical Revolutions of the Earth, are an excellent and pro- vidential contrivance, for thofe ufe- ful and necefTary mutations we have of the Seafons of the year, fo no doubt but the fame benefits accrue to thofe Revolutions, which Saturn hath about the Sun. It is vifible, that as Saturn changes its place in its Orbit, fo its King receives a variety of Afpeds (e) not only with refpedt to us, but to the Sun. Thus in one part of the Orbit it appears with a (f) larger Ellipfis, fo as to exhibit (e) Every 14 or 15 years Saturn s Ring hath the fame Face; appearing at one time with large open Anfa^ at another time with no Ring at all.

And accordingly at this very time there is no appearance of the Ring, only a fmall narrow Lift or Belt croifeth the middle of Saturn's Disk, of a colour fomewliat different from the reft of Saturn's Face, and in the place where the Ring fliould be. This appearance of Saturn is reprefented in Fig. 8. which is the ap- pearance he had through a very good 34 foot Glafs, at the latter end oF OEiob. and beginning of Nov. this prefent year 17 14. But a little be- fore this, viz,, on Sept i6. \ could through an 126 Glafs difcern the narrow Ends of the Ring on each dd^ Saturn. A Reprefentation of which I have given in Fig.^.

Thing I fliall add as only conjedural, and that is, A fuppofi- tion that the Axis oi Saturn f/^isin- cHncd (and that pretty much alfo) to the Plane of its Ring, or the Plane of its Orbit at lead ^ and that he hath a Diurnal Rotation in fome certain lliort fpace of time. For without thefe two conveniences, very large trads oi Saturn would fuffer ex- tremely for want of the Sun. For ii Saturn hath no other motion, buC that round the Sun in its Orb, one part muft be excluded from the Sun's Vifits for I J years, whilft the other partakes all the while of them,- and one Hemifphere will enjoy the bene- fit of the Ring, whilft the other is eclipfed by it : and in this cafe the (i) Mr. Huygem determines the Inclination of Saturn's Axis to tiie Plane of his Orbit to be ^igr. as that of the Earth is 23 degrees.

But fuppofing Sa- turn to move round in the fame^ or a fliorter time than Jupiter^ and in a Path pretty much inclined to the Ring, all Parts then of that vaft Pla- net will have their frequent returns of Day and Night, of Heat and Cold. And fince this is what is dif- cernible in the other Planets, and is no Icfs neceffary for the benefit and comfort of this, we may reafonably conclude the thing to be probable, although not difcernible at Saturn's great diftancc from us.

Thus Cicero^ throughout whofc Works fo many paffages of this na- ture occur, that it would be endlels to cite them : and therefore one ob- fervation that fliews what his opini- on was of the Senfe of Mankind in the matter, iliall clofc what he fiith, and that is in his Book de Legihm (d)y where he faith, Among all the tribes of Animals^ none but Man hath any fenfe of a God; and among mankind there is no Nation Jo favage and bar- barous ^ which although ignorant of what God It ought to have^ yet well knows It ought to have one.

For although by Day they may affirm fo to thee, yet by Night they are to themfelves confciotis of the con^ trary. Much more could I cite out of this famous Heathen, but one paf- fage relating to the Heavens (hall fuf- fice,* and that is in his Difcourfe {hewing Why Evils befal good Men^ feeing there is a Divine Providence (e).

Thus Ch. 2 . God's Perfection inferred. 2 1;? Thus Ctcero and Seneca: to whofe evidences I might have added many- others, particularly a great deal out of Plato (the divine Plato^ the Ho- mer of Pbtlofophers^ as he is called by the Ancients :) But it would be needlefs as well as tedious, fince thefe two former have given us the fenfe of Mankind, as well as their own opinion in the matter. Chap. IL GODs PerfeSiions demon- ftrated l?y his Works. As G O D's Works have been {hewn to be manifeft Demon- ftrations of his Exifience ; fo they are no lefs of his PerfeBions^ parti- cularly of his infinite PoweVy Wif^ dom and Goodnefs ^ inafmuch as eve- 21 8 God's Per feBton BookVIII. ry Workman is known by his Work. A Palace that fliould have nothing defcdive in Situation , Beauty, or Convenience would argue the Archi- tect to have been a Man of Sagacity, and ikihul in Geometry, Arithme- tick, Opticks, and all other Mathe- matical Sciences, ferving to make a Man a complete Architedj yea to have fome Judgment in Phyfick, and Natural Philofophy too. And fo this glorious Scene of GOD's Works, the Heavens^ plainly demon- ftrate the Workman's infinite Wtf- dom to contrive, his Omnipotence to make, and his infinite Goodnefs^ in being fo indulgent to all the Crea- tures, as to contrive and order all his Works for their good. For what lefs than Infinite^ could effed all thofe grand things, which I have in this Difcourfe ftiewn to be mani- feft in the Heavens ? What Archite6t could build fuch vaft MafTes, and fuch Chap. 2. inferred, 229 fuch an innumerable company of them too, as I have fliewn the Hea- vens do contain ?

None certainly could do thefe things but GOD. d. 3 Chap. Xjo Duties toGod Book VIIL Chap. IIL Of GOUs Relation to t/s, and the Duties rejulting from thence. IT appearing from the laft Chap- ter how great a Being the CRE- A rOR is, it is time to confider what Relarion he ftands in to us, and what is due from us to him. His Relation to us is that of CREATOR,- and as fuch, of Covijervator^ Sove- reign L OR D and Ruler, one that hath an abfolute power over us, and all thmgs belonging to us, that caa fubjed us to what Laws he feeb fit^ and that can reward or punifli us as we dcfcrve. And in this cafe, the lead we can do, is to revere and fear him at all tiraes^ to wprfhip an4 ferv^ CUhap. 3- inferred by Heathens. 251 ferve him with all our power, to comply with his holy Will fincerely and heartily, and to obey him in all things he hath either forbidden, or enjoined. And confidering alfo how great Indulgence and Love the CRE- ATOR hath fhewed in his Works throughout the Univerfe, it natu- rally follows that we ought to be truly Thankful to him for his Mercy and Kindnefs, and to love him for his Love and Goodnefs. These kind of Conclufions are fo natural, that the very Heathens have in fome meafiire made them. Thus Cicero's Stoick before cited, (a) ^ud verol hormnum Ratio non^ 8c c, IVhat ? doth not Man's Reafon pene- trate as far as even the very Hea^ vensl For we alone of all Animals have known the Rtfings^ Settings and Courfes of the Stars : by mankind tt is {a) De Nat.

THE next Inference fhall be one made by the eloquent Laclantms (aj^ Argumentum tllud quo colligunt nmverfa Coeleftia Deos ef- fe, &c. i. e.

For from hence it appears that they are not Gods^ hecatife they are not able to wander out of thofe Paths that are prefer ibed them : whereas if they were Gods, they would go here, and there, and every where without any compulfion, like as Animals up- on the Earth do, whofe wills being free, they wander hither and thither as they lift, and go wbitherfoever their minds carry them. Thus LaBantius with great rea- fon refutes the Divinity of the Hea- venly Bodies-, which on the contra- ry are fo far from being Gods, and Objeds of divine honour and wor- lliip, that fome of them have been taken to be places of Torment. Thus Comets particularly, which muft needs have a very unequal and uncomfor- table temper of Heat and Cold, by reafon of their prodigioufly near Approaches to the Sun, and as great Recefles chap. 4- Lzdiantms's Liferef^ce, 1^7 Reccfles from it. Thus according to the before commended Sir Ifaac Newton's (h) computation, the Co- met in 1680, in its Perihelion, was above \66 times nearer the Sun than the Earth is ^ and confequently its Heat was then 28000 times greater than that of Summer : So that a Ball of Iron as big as the Earthj> heated by it, would hardly become cool in 50000 years. Such a place therefore, if defigned for Habitation, may be imagined to be deftined ra- ther for a place of Torment, than any other fort of living. But above all, the Sun it felf, the great Obje<5t of Heathen Wor- fhip, is by fome of our own learned Countrymen fuppofed to be proba- bly the place of HelL Of which Mr. Siv'mden hath written a Treatife called, An Enquiry into the Nature and Place of HelL (b) Pdncipia, p. ^66. Chap. 238 Contempt of BookVIli. Chap. V. This Survey of the Heavens teaches us not to overva- lue the World, with Re- flexions of the Heathen Writers thereupon. FROM the confideration of the prodigious Magnitude and Mul- titude of the Heavenly Bodies, and the far more noble Furniture and Retinue which fome of them have more than we, we may learn not to overvalue this World, nor to fet our Hearts too much upon it, or upon any of its Riches, Honours, or Plea- fiires. For what is all our Globe but a Point, a Trifle to the Univerfe! a Ball not fo much as vifible among the greateft part of the Heavens, namely Chap. 5'. the World. 239 namely the Fixt Stars.

If therefore our World be one of the inferiour parts of our' Syfteme, why fliould we inordinate- ly feek and defire it? But above all, why fliould we unjuftly grafp at it, and be guilty of Theft or Rapine, Lying or Cheating, or any Injuftice, or Sm for it ? why fliould we facri- fice our Innocence for it, or part e- ven only with a Good Name for it, which Solomon faith (a) is rather to be chofen than great Riches 7 Why fliould we do this, if we were fure of (a) Prov* 22.
