A SPECIMEN OF SOME Animadversions upon a Book, Entitled, PLUS ULTRA, OR, Modern Improvements of Useful Knowledge. Written by Mr. JOSEPH GLANVILL, a Member of the ROYAL SOCIETY. Fr.

THe favourable Censure of the Reader is craved for what Errors have happened in Printing, which the Author's leisure hath neither permitted him to prevent nor correct: However I am to desire that these two may be thus read, viz. In the 2 Pag. of the Dedication, line the 11. for (your Supporters) read (their Supporters) and pag. 105. lin. ult. read Libavius. N. H. TO THE Reader. THE Discourse of Mr. Glanvill, was the first occasion of my writing about the Royal Society, the provocation which it gave to all sorts of men, of different Professions were such, that it might stir up any public spirit, to support so common a cause. I was sensible of the injuries he doth unto the dead, the affronts he puts upon the living, the contempt wherewith he decries that University Learning, and those Studies by which Christianity hath been supported against the Arrians, the Jews, the Mahometans, and of late the Papists and Socinians: and which if they be relinquished, I profess, that I think that the Christian Religion must inevitably fall without the aid of a Miracle. It is a kind of Apostasy from the Nicene and Athanasian Creeds to slight Metaphysics. The distinction of the Trinity, of Essence and Personality, the Hypostatical Union of the two Natures in our Saviour, and the meritoriousness of his death, (which depends thereon,) are undermined with School-Divinity; and whosoever hath any sense or value for the benefits we derive from Controversial-Divinity, either as to the quieting of his Conscience, or convincing of his Adversaries, must detest this Enterprise of Mr. Glanvill. And methinks that whosoever doth but call to mind that variety of foolish Sects, which gave the Church so much trouble in its first Infancy, and of late years, and considers that they had their Original from want of Logic, should not condemn that Art, by which men argue rightly from sound Principles. It was no less strange to me to find the names of Reverend, Sage, Grave, Disputer and Logician, perverted into terms of Contumely; yet had not all those Motives prevailed with me, but that he had so defamed the Ancient and Modern Physicians, until those late Innovators, that many importuned me to revenge my Faculty upon this Insolent Man. Besides, I had been much troubled with impertinent discourses of some, who to excuse their Ignorance in the Prognostic and Therapeutic parts of Medicine, indulged themselves in the vilifying all the ancient learning and reading, and asserting out of the Writings of the Society, the necessity and conveniency of new methods, in curing and abbreviating diseases. I soon espied my advantages over Mr. Glanvill. But perceiving his Defence so complicated, with the History of the Royal Society, that I could not well meddle with the one without reflecting upon the other; I set myself to peruse that also, and found the Errors therein so numerous and gross, and the tendency of it so dangerous, that it seemed but an easy, yet necessary work, to the Universities, and all Learning, as well as the profession of Methodical Physic, to write against these new-fashioned Philosophers; I remarked so many defaults in both books, that I was at last weary of taking notice of them, there being still Plus ultra. I resolve to give my Studies no further diversion in pursuing Mr. Glanvill; but to leave him to the scorn of some more common Pens, who being at the Universities may have more leisure than I have at present. After all this Ostentation of Learning, the things he talks and writes of are such, as he is utterly unacquainted with: the Authors he mentions he never saw, and all his discourse about the Mathematics, and Mathematicians, procured him no other acknowledgements from a Learned and Reverend Prelate, (to whom he sent one of his Books) than a Reprimand for intermeddling with what he understood not. Who can choose but smile when he reads how Apuleius improved the Mathematics a●●●● cyclide? who ●ver heard of such men as Maximus Palanudes, Achazen and Orentius? Plus Ultra. pag. 23. I suppose this last should have been Orontius, and he is so famous a Geometrician, that when Sir H. Savill (as I remember) was to seek for an instance of a pitiful fellow; this was the man he fixed upon; He tells us that the most learned 〈◊〉 of all sorts and professions; Mathematicians, Page ●. Chemists, 〈…〉 ns, anatomists, Antiquaries, and Philosophers, make up the Royal Society: but one would not guests so by their History! He tells us, that the former Methods of Science for so many Centuries, never brought the world so much practical beneficial knowledge, as would help towards the Cure of a Cut Finger, which he says is a palpable Plus Ultra Pag. 7. and 8. Argument, that they were fundamental mistakes, and that the way was not right. Can any one that hath heard of Podalirius and Machaon in Homer prate thus? Quos tamen Homerus non in pestilentia, neque in variis Corn. Celsus in Pra●at. generibus morborum aliquid attulisse auxilii, sed vulneribus tantummodo ferro & medicamentis mederi solitos esse proposuit. Ex quo apparet has parts medicinae solas ab his esse tentatas, easque esse vetustatissimas. Had our Virtuoso but known how Hypocrates had writ about Wounds and Ulcers, and that Dieg. Laert. in vita Arist. Suidas in Nicomacho, & Ammonius in vita Arist. Vide notas Menagii in Diog. Laert. l. 5. Aristotle himself was descended of the line of Aesculapius, and that his Ancestor Nicomachus was Physician to Amyntas King of Macedon, And that Aristotle also was a Physician, and writ several books (besides his Anatomy of Man) in that Science, and was upon that account valued by Alexander the Great, as Plutarch saith. And how little the Ancients stood in need of modern discoveries and aids to cure Cut Fingers, any man may judge, that knows what Scribonius Largus, and Galen (in his books de Compos. Medicam. sec. genera) have written: and how this last Author (upon Philosophical deductions) compounds several Medicaments to that purpose. In the Augustane Dispensatory, to this day his Tripharmacon, his Diapalma, his Diadictamnum, and others are recorded. And if any thing rendered Paracelsus justly famous, it was the cure of inveterate Ulcers, not green Wounds: and that therein he did outdo the ancient Physicians, is a question, I cannot grant, and have not leisure to dispute. He reckons up Five Instruments by which the latter Ages Plus Ultra. Page 10. have improved Knowledge above Antiquity. The MICROSCOPE, TELESCOPE, THERMOMETER, BAROMETER, and the AIR-PUMP. Some of which were first invented, all of them exceedingly improved by the ROYAL SOCIETY. But as for the Telescope, he confesses that to have been invented by Metius and Galileo. Which Confession of his, although it take from the Society all pretences to the invention thereof; yet it is unbecoming an inquisitive person, who might upon better Intelligence from Borellus, in his book about the Inventor of Telescopes, published in 1656. He might have learned thence that Adrianus Metius of Alkmaer did not invent them, but one Zacharias Joannides of Middleburgh in Zealand, (though perhaps Baptista Porta had obscurely proposed it) and that he who may most justly come in for a second share in the glory of that invention is one Joannes Lapreius of the same Town. And whereas 'tis generally written, that Galileo was the first who applied those tubes to the contemplation of Celestial Objects, even that appears to be false, seeing that the first Inventor, even Zacharias Joannides, (together with his son Joannes Borel de vero invent. Telescop. c. 12. Zacharides) did make use of them to discover several new Phaenomena in the Moon and Heavens. Which mistake is unpardonable in our Virtuoso (and his Assistants) because that a more particular Enquiry hath been made of late years hereinto, then ever before. The Barometer he allows to have been first invented by Torricellius, not to try the gravitation of the Air, but to prove a vacuum; Afterwards, the different ascent of the Quicksilver, being tried on the top and at the bottom of Hills in France, the opinion of the rising of the Quicksilver from the pressure of the Air, was introduced and illustrated. But nether is the gravitation, or pressure of the Air, a new opinion; it is as old as Aristotle, it is Pecquet. Exper●m 2. in Diss 〈…〉 at. p. 54. Ed raris. 1651. his, and he essayed to weigh the Air, in his book de coelo l. 4. sect. 29, 30, 39 He proves the Air to ponderate, because a bladder full of Air weighs heavier than one that is empty. Concerning which Experiment I shall add the words of Scipi Claramontius, that learned Writer, the truth of it having Scipio Claramont de universo l 14. c 3. been questioned, Possum tamen testari observationem Aristotelis dicto faventem, fuitque diligens observatio, & à diligentissimo pensatore, exactusque stateris & lancibus peracta, me praesente & adsistente, cum pluribus veritatis cupidis viris: pensit avimus ergo primum follem novum penitusque vacuum, primo statera quae solum unciarum differentiam indicabat, invenimusque unciarum decemnovem, & totidem reperimus eundem follem diligenter inflatum, & solo spiritu nulloque humore immisso: ac postea usi sumus lance, quae semuncias quoque indicabat, tumque follem inflatum unciarum decemnovem & & semis invenimus, adeo tamen ut ibi libra in aequilibrio absque tractu (ut vocant nostri) adamussim permaneret: at idem vacuus non amplius in eodem signo sine tractu, sed cum tractu perstabat. Quocirca verum dicit Aristoteles. So that whether we consider the gravitation of the Air, or its being weighed, (which Mr. Glanvill in his Plus ultra thinks so strange of, as he expresses, To have said in elder Time, That Plus Ultra p 59 c 8. Mankind should light upon an Invention, whereby those Bodies might be weighed, would certainly have appeared very wild and extravigant; and it will be so accounted for some time yet, till men have been longer, and are better acquainted Many Peripatetics (as Claramontius) 〈…〉 impure Air of ●or Atmosphere doth gra●itate, 〈…〉 deny it as to the pure Elemental Air. with this Instrument, etc. The opinion itself, and the attempt to weight it, is Aristotle's: Nor is this Discourse casually proposed once in Aristotle; but sundry times he avows the gravitation of the Air in his Problems, viz. sect. 11. probl 45. sect. 21. probl. 18. sect. 25. probl. 12, 13. From hence we may judge how well Mr. Glanvill is acquainted with the tenets of Aristotle, and how well read he is in him whom he condemns. He and his Philosophic friends dealt only in some pitiful Compendium of Physics, and from thence learned that which was the opinion of Themistius, Simplicius, and o●her eminent Peripatetics, as if it had been the avowed doctrine of their great Master; and thereupon they thus deliver themselves. And on this occasion, Sir, I observe the incompetency of their Mr. Glanvill, p. 122. judgements, who are Enemies to the real Experimental Philosophy, in that they do not (as I intimated at all, or very little, understand what they condemn. This I have some reason to say, since in the whole Compass of my Acquaintance, which is not very narrow, I profess I know not one who opposeth the Modern way, that is not almost totally unacquainted with it. And on the other side, upon the most careful turn of my thoughts among my Philosophic friends, I cannot light on one of all those that are for the free and experimental procedure, but who hath been very well instructed in the Peripatetic doctrines, which they have deserted, and most of them much Pecquet. Exper. Physico-Math. de Va●uo. pag. 10, etc. Parit 1651. Mersenni Phaenomena Pneumat. pag. 140. Par. 1644. better than those who are yet zealous Contenders for them. I might tell our Divine, that the Gravitation of the Air seems proposed in Job 28. 25. Qui fecit ventis pondus, God is said to make weight for the wind: indeed neither the gravitation of the Atmosphere, nor the notion of Aerial cylinders, pressing upon subjacent bodies, were any News in the world when the Society was first established. But the News of the Barometer is so pleasant, that I will insert the whole passage. But (IU) The BAROMETER is another late Instrument, very helpful to useful Knowledge. That there is gravity even in the Air itself, and that that Element is only Plus Ultra cap. 8. pag. 59 comparatively light, is now made evident and palpahle by Experience, though Aristotle and his Schools held a different Theory: And by the help of Quicksilver in a Tube, the way is found to measure all the degrees of Compression in the Atmosphere, and to estimate exactly any accession of weight, which the Air receives from Winds, Clouds, or Vapours. To have said in elder Times, that Mankind should light upon an Invention whereby those bodies might be weighed, would certainly have appeared very wild and extravigant; and it will be so accounted for some time yet, till men have been longer, and are better acquainted with this Instrument. For we have no reason to believe it should have better luck than the Doctrine of the Circulation, the Theory of Antipodes, and all great Discoveries in their first Proposals. 'Tis impossible to persuade some of the Indians that live near the heats of the Line, that there is any such thing as Ice in the World; but if you talk to them of Water made hard and consistent by Cold, they'll laugh at you as a notorious Romancer. And those will appear as ridiculous among the most of us, who shall affirm it possible to determine any thing of the Weight of the Wind or Clouds. But Experience turns the laugh upon the confident incredulity of the Scoffer; and he that will not believe, needs no more for his Conviction, than the labour of a Trial. Let him then fill a Tube of Glass, of some Feet in length, with Quicksilver; and having sealed one end, let him stop the other with his Finger, and immerge that which is so stopped into a vessel of Mercury, the Tube being perpendicularly erected; let him then subtract his Finger, and he will perceive the Quicksilver to descend from the Tube into the subjacent vessel, till it comes to 29 Digits or thereabouts; there, after some Vibrations, it ordinarily rests. The reason that this remainder of the Mercury doth not descend also, is, because such a Mercurial Cylinder is just equiponderant to one of the incumbent Atmosphere that leans upon the Quicksilver in the Vessel, and so hinders a further descent. It is concluded therefore, That such a Cylinder of the Air, as presses upon the Mercury in the Vessel is of equal weight to about 29 Digits of that ponderous Body in the Tube. Thus it is when the Air is in its ordinary temper: but Vapours, Winds, and Clouds alter the Standard; so that the Quicksilver sometimes falls, sometimes rises in the Glass, proportionably to the greater or less accession of Gravity and compression of the Air hath received from any of those alterations; and the Degree of increase beyond the Standard, is the measure of the additionable gravity.— There is something so charming and so divertive in this discourse, that I cannot yet dismiss it, notwithstanding what I have said out of Aristotle and Claramontius. That there is Averro adheres to Aristotle, and holds the Air doth gravitate. gravity even in the Air itself, and that that Element is only comparatively light, was of old made evident by the Man of Stagira: nor did the Schools hold a different tenet, if you take Air for this impure mixture and Sphaera vaporosa about the Earth, which we breath, and in a special manner have to do with: as appears from Claramontius in his Book of the Universe, and Septalius upon Aristotle's Problems. But Mr. Glanvill neither understands what he opposeth, nor what he Asserts. For in the beginning he speaks of the gravitation of the Element of the Air; whereas that Instrument called a Barometer proposeth only a way to measure the degrees of compression in the Atmosphere, in which Region I believe no man ever denied but that the Aqueous and Terrestrial corpuscles interspersed had their weight and pressure: Thus the ordinary temper of this Air (which is never pure) the alterations of it by vapours, winds, clouds, are the subject of those contemplations, as any man knows that reads Mr. boil, or even Mr. Glanvill. Thus all the flourish of Rhetoric comes to nothing, the wonder is ceased, and we come to try only a more particular way of examining the weight of a body, which no man in his wits ever denied to be ponderous. And here I must tell our Virtnoso, that his reading or consideration extends not so far as to the writings of Mr. boil, and the experiment in him. For it appears out of Him that F eri●▪ Phy●●c-Mechan. E▪ per. 7. the Mercurial Cylinder riseth and falls in the Magdeburgical Air-Pump, according to the lessening or vigorating of the Spring of the Air: and that upon putting in the Barometer, and closing the Engine, there appeared not any change in the height of the Mercurial Cylinder, no more than if the interposed Glass-Receiver did not hinder the immediate Besides, the difference in Quicksilver is such, that all Writers take notice of it, and I am apt to believe the Phaenomenon may be much varied in the Cylinder, according to that. pressure of the ambient Atmosphere upon the enclosed Air; which hereby appears to bear upon the Mercury, rather by virtue of its Spring then of its weight. And if this Phaenomenon proved such in a greater and less Receiver, with a greater or less cylinder of Mercury (it being indifferent which is used,) I doubt this Barometer will not determine the strength of the Spring of the Air, much less its weight. For the Elasticity is a distinct consideration from the weight of the Air: as when some Experimentators went about to weigh the Pike, the Flownce or Spring of the Pike was no part of the weight of the Pike, though it might turn the Scales. This sole consideration destroys all the great promises we have from the Barometer, for if the Spring of the Air cannot be exactly known, that we must be for ever ignorant of the nature of those other bodies which influence and press upon our Air, and compress the Spring of the Air, and may have many operations upon it which we know not, neither can comprehend; If the height of the Atmosphere cannot be determined, (which I make a postulatum of) the alterations in the higher Regions are unsearchable, and the mechanismes of those corpuscular combinations incomprehensible, I shall not doubt to say, that there is not yet found out a way to measure ALL THE degrees of Compression in the Atmosphere: nay, 'tis far from that exactness; for the body of the Quicksilver varies not upon insensible variations in the Air: the intercepted Air in it takes off from the Niceness of the Experiment: and since even heat, (and perhaps other circumstances) adds to the Spring of the Air, it cannot give us that account pretended, about vapours, winds and clouds. The Essay by Tubes and Quicksilver, as ingenious as it is, yields the Society no further glory, then to have illustrated it, and perhaps to have made some further Experiments in it then those had done, to whom, as the first Inventor, (by the concession of the Historian) appertains all or most of the Honour which ariseth from such accessionals. It is true, our Virtuosos fixed on it the name of Barometer, but they had done better to have called 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉, or 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉, or Gas, or Blas, or Diaceltateston, or some such unintelligible name, rather than have termed it thus: the Appellation signifying no more an instrument to measure the gravity of the Air, than an instrument to weigh a parcel of Tar, or indefinitely a pair of Stillyards. The Aerometer might have been a little more Emphatical; especially considering that 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 and 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 are Synonimous. Had not Aeroscopium been accommodated to the Thermometer, it would not have been much incongruous. But I conceive, that Aerobaricon or Aerostaticon would have fitted the Experiment as well as any name I can now think upon. The Barometer was invented by Torricellius to prove a Vacuum, and in Mersennus' Cogitata Physico-Mathematica, you may find it applied to the examining the difference of the Air in several places. The Air-Pump was found out at Magdeburgh, and not in England; it was first published by Schottus, under the name of Instrumentum Magdeburgicum. Mr. Boil amended it, and prosecuted many ingenious Experiments in it, for which all Philosophers are redevable to him, but cannot proclaim him the Inventor of the Instrument, no, nor of the (notion of the Elasticity Hen. Reg. Philos Nat. l. 2 c. 12. p. ●4. & l. 2 c. 3 p. 173. ed. 1661. of the Air, which was proposed first to the world by Henricus Regius, under the name of the spontaneous dilatation of the Air: and illustrated by Pecquetus, who first, (that I know of,) spoke of the Elater, Pecquetus pag. 19 (quem elaterem nuncupo). The Microscope was invented by the aforesaid Borel ubi supra c. 12. p. 26. Blancanus de mundi fabr. part. 3. c 2. Zacharias Joannides: The Thermometer, or Thermoscopium was first the invention of Sanctorius; so Blancanus saith, Audivi Doctorem quendam medicum Patavii degentem, qui Sanctorius cognominatur, hujus esse inventorem And now I demand of our Virtuoso, which of these Five Instruments for the Improvement of knowledge have been found out by the Royal Society: The Thermometer is the discovery of a Galenical Physician; but as to our Virtuosos nothing appears but the pretention to other men's discoveries, and the improving of them. By the Benefit indeed of one of these Instruments, the Telescope, we are put in hopes to find a sure way to determine those mighty Questions, Whether the Earth move? or, The Planets be inhabited? And who knows which way the Conclusion may fall?— I perceive hereby that Mr. Glanvill is not altogether convinced that the Earth moves; and I am as little satisfied, that the solution of those Questions is so mighty and important a thing; for if the Earth stand still, than things will be as they are now: and if it be determined otherwise, yet shall we not need to fear that the Revolution of the Earth in its Diurnal motion, either shake our houses about our ears, or shake us off by the tangent line: and as for those inhabitants of the Planets, in case all our other trading should be lost, we shall not find out any gainful commerce with them; nor need we dread that they will piss out our Eyes as we look up. So that let their Telescopes be brought to that unimaginable perfection, whereby to discover the inhabitants of the Planets as plainly as mites in Cheese, and let the Conclusion fall which way it will, things will fall out no otherwise than they do. He inveigheth bitterly against Aristotle for his Heathen-Notions, and in his Preface to the Clergy of B. & W. wishes that the devoted Admirers of Aristotle would study his Rhetoric, History of Animals, and Mechanics. I wonder he did not recommend unto them the perusal of his Ethics. Certainly they deserve as much to be read in these days, as any Piece. And perhaps his Politics might contribute something to the instruction of a Nation. But how dare herecommend any book of that man of Stagira to be read, if those motives that swayed him to Anti-Aristotelism, be of any validity: Alas! he is troubled at his Heathen-Notions! Oh! rare Puritanism! But my dear Brother Scruple, ought any one to be offended at every thing that is of Heathen-Original, though it contain nothing of Gentilism in it? Represent your adversary as you please to his Diocesan, nothing hath more of the Presbyterian and Fanatic than this Topick. Moreover, what do you think of those Atoms and Corpuscles? are they not Heathen-Notions, and decried by the Fathers? what do you think of the terms used by the Mathematicians? what of the Languages, such as are not Sacred? what of the months, days of the year, and the names of the Stars, Constellations, etc. Must every thing be reform according to the Coelum Stellatum Christianum of Julius Schillerus? Besides, these words in Theology, of Unity and Trinity, have as much of Heathenism in them, as they have of Platonism. I shall here take further notice of his exceptions against Aristotle, as they are Recapitulated here (though they are more largely proposed by him in his Letter against Aristotle, which I have fully answered in a distinct Treatise) the general censure whereof is, That they are nothing but Lies, and such as no man that is acquainted with any thing of ancient Literature could have uttered. I protest in the Presence of Almighty God, that if there be not great care taken, we may be in a little time reduced to that pass, as to believe the story of Tom Thumb, and all the Legends or falsifications of History, which the Papists obtrude upon us! This Philosophy fairly disposeth us thereunto, by taking us off from the Pedantism of Philology, and ancient reading, and by accustoming us to believe the forgeries they obtrude upon us. Methinks herein he is one as absurd as that Romish Monk was in the Pulpit. Heresbachius I. C. citante Taubmanno, J● H●n H●ttingerus in 〈◊〉. Oriental l. 1. c. 2. p. 2 audivi, inquit, Monachum in Ecclesia declamantem, qui, nova, inquiebat, jam reperta est Lingua, quae vocatur Graeca, ab hac sedulò cavendum: Haec enim est quae parit omnes omnes istas heraeses.

We are running on as fast as we can to this condition of ignorance, and shall be so enured to Historical untruths, magisterially imposed upon us, and disused from enquiring into them, as to believe any thing. He tells us the Aristotelian Philosophy aims at no more, than the instructing men in Notion and Dispute, that its Design was mean, and its Principles at the best uncertain and precarious,—— One may guests how well our Virtuoso understands the Old Philosophy, to ascribe that unto it all in general as its aim, which is but the intendment (and that a necessary one too) of the Dialectic and Metaphysical parts. In Natural Philosophy their designs were the same that our Moderns boast of, if they miscarried in the main, let us pity their misfortunes, but not blame their intentions. Did Aristotle in his books of Animals, or Theophrastus about Plants, instruct men only to Dispute? Had his Anatomy, and his Problems nothing but Notion? Must we cast off all Notions? Or ought we to endeavour after the gaining of clear notions of things? If men hitherto did proceed no further, and yet pretended to be Peripatetics, blame the abuse, but condemn not the Philosophy, which hath nothing in it that puts a stop to Inquiries and Curiosity. Nor do I find that those Physicians, and others, who advanced the several parts of Natural Philosophy and Physic, did thereby act contrary to the rules of their Master or Tutors. It is true, that their Schools did meddle but with few points mainly, and those were such as related to Divinity, as the Eternity of the World, the Nature of the First and Second Causes, of the Soul and its Faculties, etc. as to an exact natural Philosophy, they did not much trouble themselves, nor had we had what we have, but that Averro and the Physicians befriended us. But must Scaliger and such like suffer under these Imputations, which particularly relate unto their School-Divines? and must they also be blamed for not teaching nor putting men upon further Inquiries than were necessary to that Christianity, which they were to support against the Mahometans and Jews? He that knows the end of their first institution by Charlemaigne, can best judge how prudential it was, and how they answered expectation. But our Illiterati know nothing of that, and are always reviling them where they are not faulty, and would have had them nglected that part which was necessary to the Education of all that were to live under and support Christianity, to pursue Studies that contribute little thereto, and such as were never essential to the being of a State, but have been often exploded as prejudicial thereunto. The same Apology may serve the present Universities, who do enough in breeding up men to be fitly qualified for Employments in Church and State, and instruct them in so much Philosophy as is necessary for the explaining and defending of our Religion against Atheists, Papists, and Socinians: and whosoever shall put the accurate debate of these Points, the Art of reasoning, the Validity of Consequences, the unfolding of crytical Syllogisms and Fallacies, the general doctrine of Topics, the Moral Philosophy, and Foundations of Civil Prudence, (besides Civil and Ecclesiastical History and Languages) which are taught there, or aught to be by their Constitution, into the Scales on one hand, and the Mechanical Education (recommended with all the advantages that ariseth from Aphorisms of Cider, planting of Orchards, making of Optic Glasses, magnetic and S●e Mr Sprat, p. 329. hortulane Curiosities) on the other hand, will be able to judge easily which Studies deserve the most encouragement by the public, and which are most useful and requisite. Having said thus much in behalf of our University-Learning (which is now contradistinguished from the Mechanical Education) I shall add thus much in favour of our Ancestors, who gave solemn encouragement to Archery, Cudgel-playing, Foot-ball-playing, and other Exercises, that prepared the Vulgar to Military Performances; as the more Academical did the Gentry to State-affairs: whereas they gave little countenance to the Experimental Philosophers and Naturalists: that the practice is justified by Vegetius l. 3. c. 10.

Alchym Qu●●. not the Chemical Principles so much of uncertainty, as they have of Equivocation? Are not they precarious too, and suspicious? Are there any of those that agree amongst themselves? and do not they as little agree with Nature as those of the Peripatetic way? I will not doubt to maintain that as far as Physic is concerned in the debates; The ancient Philosophy better agrees with the Phaenomena of Nature, and carries us on with more assurance to work (as they phrase it) than any other, and that the diligent reading of Vallesius, Mercatus, Saxonia, Claudinus, etc. shall produce better Physicians than Silvius, Helmont, or Odorode. And whosoever resolves any of the other Questions in the Negative, whatever he pretend, hath never considerately studied the Points. Give therefore the Aristotelians leave to hold an Hypothesis, which is accommodated to the polity of our Nation) at least as revocable, till a better be introduced; and do not proceed in an exterminative way, till something else be ready to be substituted. If Notions might be rejected for being first proposed and used by Heathens, then is not Aristotle in a worse condition than Epicurus, Democritus, Plato, or Pythagoras; If Impiety in the Teacher may authorise us to reject doctrines not impious, I think the condition of our Stagirite not to be worse than that of other ancient Philosophers, and better than some of the New. That there is impiety enough in Gassendus' Answer to Des Cartes, any Christian will grant, especially if he be a Protestant. And the life of Des-Cartes had but little of the Saint: this is I cannot find any ground to conclude Aristotle so wicked. If we indemnify him for having an hand in poisoning Alexander, (which perhaps is not true). In his last Will, there is much generosity: in his life, many testimonies of a singular virtue: ●n his discourses much wit and worth. He writ an Apology for Piety; got the walls of his destroyed Country to be rebuilt, and made excellent Laws for it. Philip chose him to breed up Alexander. And those are greater assurances that he was not so wicked, as he is reported by his adversaries▪ They repeat nothing but old lies, such as Apellicon refuted: and Aristocles saith, 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉. Se● Casaubon upon Diog. Lart. manifest. And I desire Mr. Glanvill to acquit Paracelsus from being impious in his life, and many of his doctrines. If he was a Corrupter of the Wisdom of the Ancients, for mis-citing, and misrepresenting their opinions; and must therefore be condemned and rejected: who can approve of Mr. Sprat, Mr. Glanvill, and their Adherents? He saith, that Aristotle was of no such superlative Account in the wisest times. But he tells us not which those most wise times were, when he was in disesteem. I have not read of any more wise people, than Greece, Rome, and the Mahometans, under their first Caliphs' and King Almansor. And yet all these admired him at several times. He that chargeth Philip of Macedon, Alexander the Great, and his Successors, (particularly the Ptolemy's of Egypt,) with Folly: and Sylla, Tully, and those other Romans that admired him, with want of wisdom; Or, who thinks that the Empire of the Moors, and their Academies at Bagdod, Fez, and Cordula, were composed of a sort of Simpletons, may go seek for the wise and the prudent in Gotam College. And perhaps those Christians that celebrated Aristotle, and advanced him to that repute in their Kingdoms and Universities, were not Idiots or Changelings. That He was much opposed and slighted by the first Fathers, is an Objection that hath some truth in it, but not much to the particular prejudice of our Stagirite. For at first they hated and detested all humane Learning, and Philosophy; and when they came any of them to admit of those Sciences, than they divided into the Aristotelians and Platonists, as they did into Arians and Catholics: That the Arians were Aristotelians, is to me as evident, as that Mahomet taking the advantage of that faction, and of the brutal lives and ignorance of the Catholics depending upon the Patriarch of Constantinople, did advance the Sect of Christians, called Mahometans; and his Successors the Caliphs', did wholly employ themselves to improve 〈…〉 that the Virtuosos would inquire after the Peripatetic Philosophy, at Alexandria after the Ptolemy's and not at Athens. And when they have done that, and studied the condition of Christianity, during the time of the Arrians, and enquired into the rise of Mahomet, the circumstances that advanced him, and contributed to the spreading of his doctrine, and increase of that Empire under the Caliphs', than they will be able to judge of the truth of what their Historian, and Mr Glanvill writes in the books animadverted on, and in his Letter concerning Aristotle. the doctrines of Aristotle and the Peripatetics. So that Aristotelism, Arianism, and Mahometanism issued out of the same parts of the world, viz. Alexandria, and the adjacent Country's: Nor was it Chance or the black ignorance of the Age, but great prudence in Charlemagne and his Successors in the West, that brought in Aristotle: as any man will say that understands the circumstances of those days. But so much History is above the reach of my Experimental Philosopher: To supply that defect, Christians must be once more told, that since their minds are enlightened with the rays of the glorious Gospel, they have less reason to bow down to the Dictates of an Idolater and an Heathen. And so farewell to the Rhetoric and other works of Aristotle, which our Virtuoso a little while ago recommended unto us. Let us shake hands with Seneca, and Epictetus, and Plato: and join with Tertullian in that saying. Nobis Philosophia opus non est post Jesum Christum, nec Aristotele post Evangelium. Having said thus much to these grand accusations against Aristotle, with which Mr. Glanvill was so perplexed, I suppose he may think that a more devout Admirer of Aristotle than I am, with more time, may say enough to convince him, that it was his fault, and not the Peripatetics, that he benefited so little by them. And I pray what language did Epicurus, Pythagoras, and Philolaus make use of? He writ better about divine things than Plato, as Vossius witnesseth, Quanquam multa de Deo scripta sunt a Platone, accuratius tamen apertiusque de iis egit Aristoteles. He citys a passage of Plato, 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉, and adds, that the Universe must be known by the Art, by which it was made. If it be not to be known any other way, it is unintelligible. Let him answer Dr. More's Dialogues upon that point, where he explodes the Mechanism of Nature: and reckons upon Des-Cartes as the most prodigious Fool that ever was, for holding that opinion. I shall add, that Geometricians are commonly a sort of men, that being once got out of their Science, they are far from being elevated and improved thereby: And the reason is, because that the severe procedure of Mathematical demonstrations, and their ways they take to demonstrate things appertaining to their Science, these do not qualify a man at all for those argumentations which sway and guide in Metaphysics, Ethics, Politics Arist Eth. l. 6. c. 8. and Religion itself. Upon this account Aristotle observed, that a child might become a Mathematician, but not a Politician, or Moralist. Hence it is, that Geometricians, (except their studies have particularly acquainted them with those dialectics, which regulate the generality of Mankind in such discourses,) seldom, if ever, prove Metaphysicians, Religieuse, or otherwise of tolerable ratiocination: either rejecting as false, frivolous, and demonstrable those reasonings and studies, according to which humane affairs are regulated; or else ignorantly, running into Whimsies, and fantastical ways of arguing. Neither is this more manifest, than I think these two Conclusions are, which I deduce from thence in opposition to some Comical Wits in their History, viz. That by how much more general as to public and private use and emolument in order to domestic affairs, or Civil Prudence and the preservation of Humane Society and Government those things are, which depend upon persuasive Arguments, and those topics and methods of ratiocination which are laid down by Aristotle, not Euclid: by so much those courses ought to be pursued, upheld and encouraged by understanding Statesmen which are subservient thereunto, above the less necessary and utile Mathematics. Next, That the Mechanical Education, or that whereby Hist of the R▪ ●. p. 319. Youth are enured at first to vigorous demonstrations, and necessary deductions from evident Principles, and a Philosophy that is purely Corpuscularian, ought not to be premised or preferred to other studies in order to the fitting men for humane life: seeing either accidentally, (yet so, as in regard of our depraved nature it is almost unavoidable) or intrinsically those courses dispose men's minds afterwards to Atheism, or an indifference in Religion, and inhabilitate them towards those more important, but less delightful studies of Law, Policy, and Religion, with their several dependencies. I find that Aristotle hath complained of some, that in their Explications of Nature made too much use of Geometry. Magnenus hath complained also of them; and Conringius, Bullialdus, and Ricciolus, of Kepler; and Bodinus, in his V de Ricciol●m in Almagest no●. l. 4. p 278.

And if Plato was so solicitous, that none but Geometricians should come into his School, yet he sent them very fools out, if they allowed See Mr. Parker's censure of the Platonic Philosophy. of his Logic and Physiology. I shall leave the further defence of Aristotle to others; only I must tell him, that Vossius in his account of Geomatrician allows of Aristotle for no mean one. And we find that he supposeth his Scholars not ignorant in Geometry, since without that knowledge they could Vide Blancanum in loca Mathematica Aristotelis. not understand his Analytics, nor that part of his Ethics, where he illustrates Justice by the Arithmetical and Geometrical proportions. And as for his Ethnical opinions, it is ridiculous to upbraid the University-Learning Epicurus Mathesin insuper habuit: unde ut Plutarch, ait libro contra Epicurum.

He tells us that Archytas, that great Geometrician was scared from Mechanical and Organical Methods to the great hindrance of beneficial Improvements that way, so that he kept himself up in Abstractive Contemplations.

I wonder oftentimes how He did to commit so many mistakes; and I cannot believe that He or his Philosophic friends were ever well instructed in the Peripatetic doctrines, who are so ill taught in all manner of Humane Learning. I resign him up to be the scorn and entertainment of others henceforth. Nor will I engage particularly in the dispute betwixt him and Mr. Cross. I am informed, that the Relation is very false; and I profess I have no mind to believe this Virtuoso in any thing he says. It is easy for him to misreport a private discourse; His great and admired friend Mr. Sprat relates general Encounters false; He tells us, Of a mischance that befell the Christian Army in Egypt in the time of the Hist. of the R. S. Pag. 412. Holy War. Their strength was great and irresistible, if they had only understood that which every Egyptian could have taught them, the course and the time of the overflowing of the Nile. For the want of that slender knowledge, the bravest men of all Christendom, were led up to the Neck in the River, and were forced to yield to the Enemy's conditions without striking a stroke. This was occasioned by the stupidity of the Cardinal who commanded them. If he had been less skilful in the Schoolmen and more in Nature, that dreadful disaster had never happened.— Such an untruth as the Historian tells here, such perhaps is the Narrative of what passed betwixt him and Mr. Cross. I cannot find any such Story in Fuller's Holy War, but the contrary, viz. Egypt Fallers Holy War, l. 3. c▪ 27. is a low level Country except some few advantages, which the Egyptians had fortified for themselves. Through the midst of the Land runs the River Nilus, whose streams they had so bridled with banks and sluices, that they could keep it to be their own servant, and make it their Enemy's Master at pleasure. The Christians confidently marched on, and the Turks perceiving the Game was come within the wile, pierced their banks, and unmuzling the River, let it run open mouth upon them, yet so that at the first they drowned them but up to the middle— not to the neck. There is no body charges the Cardinal Pelagius, who was Legate, and commanded the Army there, for invading Egypt in an unseasonable time, nor with being ignorant of the time when Nile did overflow. The Christians were not ignorant of that, who had discovered and invaded Egypt before in 1218, and this was but two years after in 1220. The Egyptians, 'tis true, dammed up the River (which was now low) and upon the approach of the Cardinal cut their banks, and so gained the victory. That the Cardinal was no Soldier, and unacquainted with Stratagems of war, I grant; and for this Historians▪ condemn him, but not for being ignorant of that part of Natural Philosophy. A Member of the Royal Society published lately an account of the Original of Nile. The Description had nothing of News in it to any Scholar, that was material. But they should have procured an account of the manner of the inundation of Nile, for the Historian is more ignorant than the Gardinal of it. Had it been the time of the beginning of the overflowing of Nile, they might have retired easily to Prosper. Alpin. de Medic. Egypt. l 1. c. 8. Damiata without damage; for it never exceeds in rising above ten inches each day, sometimes it ariseth not eight inches. Just such an Account, I fear, doth I know not what Logic Mr Glanvill read at Oxford, but 'tis Ignoratio Elenchi in him, to oppose what Mr. Cross might say about Asia as 'twas of old named, and bounded▪ and traveled over, with the new discoveries of China, Japan, etc. which rather constitute a fifth part of the world, then are included in Asia. That is Asia, which they imported that gave it the name, not what others affix to it. By the same Sophistry it may be said that the former Kings were not Kings of France, because late Conquests have enlarged the borders. Nor was Aristotle implicitly guided by the relations of those Hunters, etc. he diligently inquired into their reports, and oftentimes refutes the vulgar stories. See this particularly asserted by Federicus Bonaventura de partu Octomestri l. 5. c. 60. Mr. Glanvill give of Mr. Cross' discourses, whom report speaks so advantageously of, that we must give the Lie to general fame, or believe him a very learned Person, as well as pious. Perhaps he, as well as my Lord Eacon might suspect the truth of those Telescopes. And perhaps also he might be mistaken in saying that Aristotle did travel all over Asia: yet, however that, that Jonssius (the Script Philos. l. 1. c. 18.) disproves that opinion▪ yet no less man than Josephus l. 1. adv. Apionem, was deceived as well as Mr. Cross. Solinus also c. 14▪ and Ammonius in the life of Aristotle say, that Aristotle did accompany Alexander in his Asiatick▪ Expedition. And I profess myself in an error as well as Mr. Cross, if it be not true, that Aristotle had sundry advantages to pen his History of Animals which our Virtuosos want. Pliny Nat. Hist l. 8. c. 16. saith▪ Alexandro Magno rege inflammato cupidine animalium naturas noscendi, delegataque hac commentatione Aristoteli, summo in omni doctrina viro, aliquot millia hominum in totius Asiae, Greciae que tractu parere jussa, omnium quos venatus, aucupia, piscatusque alebant: quibusque vivaria, armenta, alvearia, piscinae, aviaria in cura erant: nequid usquam gentium ignoraretur ab eo: quos percontando, quinquaginta fermò volumina illa praeclara de animalibus condidit. Let a man now consider the greatness of Alexander, the impatience he had to effect his purposes, how generous he was in acknowledging Services, and how vindicative when neglected, and how understanding to know what was done and omitted: Let any man consider this, and he will think that the Society have not a Patron that interesseth himself so much as Alexander did for Aristotle. He had several thousands commanded to give him intelligence: their number transcends any that ours can pretend to: their quality is such as the R. Society wisheth for, viz. Intelligence from the constant and unerring use of Experienced men, of the most unaffected Mr. Sprat. p. 257. and most unartificial kinds of life. And if notwithstanding all these circumstances Aristotle were abused or mistaken, or defective in his Narrations, I am confident there is less credit to be placed in the Narrations of some of our Virtuosos, who have been so mistaken in their Accounts of Cider and Salt-Peter, domestic Inquiries; what man will give himself the trouble to inform them, either at home, or abroad? with what negligence and imperfectness will they register things? how un-philosophical will their memoirs be? How will they be able by entreaty to procure a second information? That there are more parts of the world discovered and sailed unto then in Aristotle's time, I grant. But what certainty shall we have of Narratives picked up from negligent, or un-accurate Merchants and Seamen? What judgement have these men of no reading, whereby to rectify or enlarge their Inquiries? Mr. Glanvill doth not so much as know who writ well upon the several subjects, in which he pretends that the Moderns have outdone the Ancients. As Improvers of the History of Baths (by the way we are far inferior to them in the practice of Bathing) he reckons Savananla for one: he might as well have recounted Bayrus, Gordonius and Gatinaria: or any of the barbarous Physicians, for advancers of the practic: He might have told us of a Volume of Writers de balneis: But why did he omit Solinander de thermis, Libavius, and our Dr. Jordan (who lived at our bath) and Bauhinus de fonte Bollensi, and the other Writers about particular Baths? Alas! He knew them not: nor did I ever hear any man commend Blanchellus upon that subject. About Minerals, could he not have named Encelius, Caesalpinus, Fallopius, and Lazarus Erkerus, whom I find by some to be preferred before Agricola? In his Account of remote Histories of Nature, could he remember the Author of the Caribby-History, and pass by Carolus Piso, Burggravius, and Bontius about Brasile and the East Indies. So where he speaks of discoveries made by Microscopes (pag. 57) by naming only Dr. Power and Mr. Hooke, ingenious Mechanics, Members of the Royal Society; he seems to intimate, as if none but the Virtuosos had proceeded in that adventure, whereas Petrus Borellus, Physician in ordinary to the King of Erance, published a Century of Microscopical observations An. Dom. 1656. such as have (if true) more of utility than those of Mr. Hooke, though less of curiosity, and destitute of Cuts; and Kircher after many years employed in those contemplations, per exquisitissima Microscopia, did Kerch. de Pest sect. 1. c. 7. publish several Experiments of that kind, in his book de Peste; and Nicolaus Zucchius about the same time (1656.) Nic. Zucchius Philos. optic. part. 2. 〈◊〉. 3. c. 7. sect. 4. p. 348. published a short account of Microscopical observations, about a Louse, a Flea, the feathers of a Peacock's tail, etc. encouraging others to prosecute the work. He tells us, (pag. 56.) that the discoveries by Telescopes may inform us of the Longitudes: upon which must needs ensue yet greater improvements of Navigation, and perhaps the discovery of the Northwest passage, and yet unknown South. I grant that the invention of Longitudes will be extremely beneficial to mankind in point of sailing: and the R. S. have made great boasts how that it shall be achieved by their Members; and thereupon caused some projects to be rejected, which yet perhaps would have proved as unfeasible as the attempt of Galileo's▪ to calculate it by the Medicean Stars. I desire much to see the happy result of our Virtuosos, though the consequences here affixed to it, as Improvements was very defective. I shall propose some Scruples about the Northwest passage, and ●he utility of its discovery, as also of the hopes of finding out the Southern Tracts. First, I say that the story about the straits of Aman See Mr. Gardiner in his description of America c. 25. where he professeth to write nothing but what his own knowledge, or good intelligence persuaded him unto, he having lived long in the remote parts of America: the loss of whose large Account thereof we may deplore. is very improbable, if not certainly a Fiction. It hath been so thoroughly searched into by our Nation, that there is no encouragement to a further trial: and this Straight of the Northwest passage, is indeed nothing but a narrow difficult passage to Button's Bay, the entrance being properly called Hudson's Straight, in regard of his first finding it; the mouth whereof lies in 62 degrees. But were there such a passage, it would much more concern the Portugals, and the Spaniards, and Dutch, than it doth the English; for their trade is to the North-part of the East-Indies, and ours to the South: theirs to the Moluccoes, Philippinas, Japan, and China; whereas we seldom pass beyond Bantam am in Java. Secondly, were there a passage that way, yet it were not to be chosen before the other: for, could a man sail in a straight line, first from England to the Straight, and thence from the Straight to the East-Indies, it would prove a further way than the other by the Cape of good Hope. But those that know any thing of those Seas, know that the Sea-Course to any part of North-America, is as low as 23, 24, 25, or 30 the highest by reason of the wind which bloweth in the South-sea East and West▪ as well as in the North, that is to say, for the most part West without the Tropics, and almost constantly East within them. Wherefore you must go out of your way as well from the North-part of America to the East-Indies, as from England to this supposed Streight: and there is as much difference in relation to pleasantness in the Voyages, as between Summer and Winter. For when one is clear of the Bay of Biscay, in all the Voyage by the Cape you find no cold weather till you return to the same place again: but on the contrary, it is so cold and Icy about the Straight in the middle of Summer, that there is no making Judge hence what hopes there is of making discoveries in the Southern Tracts. way without much difficulty and trouble. And in the South-Sea, where the Sun keeps the same course as in the North in June; Sir Francis Drake in compassing the world, found so much cold in thirty eight degrees of North-latitude, that he was forced into a Southerly course. Besides, if we may take a conjecture from the winds, which have blown when the Undertakers for that discovery passed into those straits, one would guests by their great coldness, that they did blow from the Land, and consequently that there is no Sea to the North of America, but that the Land of this New World reacheth by the North parts, even to the Northwardly Provinces of Tartary, etc. I am surprised to find, that Mr. Glanvill doth not make the Moderns to surpass the Ancients, in Architecture, Sculpture, Picture, and several other Arts of ingenious Luxury. That he doth not advance the glory of our Mathematical burning- Glasses, above the Specula Ustoria of Proclus; and the Artificial Fires of our Virtuosos above those invented by Callinicus, when he burned the Saracens Fleet. But not to upbraid him with what he hath omitted: I shall resume the discourse about Telescopes, and their fallaciousness, wherein if Mr. Cross was a little doubtful, yet Mr. Glanvill is so assured, that he makes an ample recital of the contest, and the advantages he gained in it. I shall set down his words, the better to divert my Reader, and to show how insupportable such kind of men are in all judicious and intelligent company. To my Discourse about the Dioptrick Tubes, the Telescope Mr. Glanvills Plus Ultra. c. 9 p. 65. and Microscope, the Reverend Disputer replied, [That our Glasses were all deceitful and fallacious] Which Answer minds me of the good Woman, who when her Husband urged in an occasion of difference, [I saw it, and shall I not believe my own Eyes?] Replied briskly, Will you believe your own Eyes before your own Dear Wife? And it seems this Gentleman thinks it unreasonable we should believe ours▪ before his own dear Aristotle. For an assurance of the credit of those Glasses, I told him he might try them upon objects near, and easily visible by the unassisted sight; and if he made the trial, he would find they altered the objects in nothing but their proportions▪ which are represented larger for the advantage of vision in things small and remote; and we have all the like reasons to distrust our Eyes, as these Glasses (for their informations are the same in all things, but the mentioned difference) and there is no man so much a fool as not to make allowances for that. Never was any yet so grossly deceived by the Microscope, as to be persuaded that a Flea is as big as a Lobster; nor did the Telescope ever make any one believe that the Moon was at the end of his Tube: But if the former represents that little Creature as bristled and jamared, and the other makes the Planet mountainous and uneven, we have no reason to believe but that their reports are sincere, though our unaided Senses are too gross to perceive either the one or other; since, if the mentioned bristles and jamars are in the Glass, and not in the Animal, they would appear in like manner in all the small Creatures which in the same light and position are looked on through the Microscope: And if the ruggedness of surface were in it, and not in the Moon, the same would be seen upon all other distant Objects, that are viewed through the other Optic Instrument. And if there be deceit in those Glasses, Seamen had need beware how they trust them, since the Flags which appear to be those of their Friends in the Perspective, may be really the Colours of their Enemies. Upon these Accounts, Sir, which afford plain and sensible evidence, I wondered much at the Disputers strange suspicion, which had been scarce pardonable in a vulgar head; and I know not what to call it in one, that would be thought a Philosopher: But the wary man gave a reason, which made me as much wonder at his Argument, as his Doubt. And to this attend Ye Philosophers of the ROYAL COLLEGE, and prepare yourselves to answer a Demonstration from Experience against your Glasses; Raise your Expectations for a wonderful, convictive Experiment; Let the Mountain's travel, and the Birth will follow. [Take two Spectacles (saith the Experimental Sage) use them at the same time, and you will not see so well as with one singly.] therefore your Microscopes and Telescopes are Impostors. This man, Sir, is a Logician, and no doubt you perceive so. O how I admire this rare faculty of arguing! How dull are our Wits, to those subtle, Eagle-eyed Schoolmen, who see Conclusions so far off, through the more unerring Telescopes of their own piercing Understandings? Did ever old man before make this use of his Spectacles? But to leave wondering, let's endeavour to understand this Philosophy of Chue. How a man may see by Spectacles, that Perspectives are deceitful. [We can see better through one pair, than two] saith the deep Philosopher. Most sagely observed! The Argument begins strongly: But in the name of Aristotle, whence comes the Consequence? Therefore Perspectives are fallacious. " One Proposition for Sense, " And th' other for Convenience. This fits his purpose to discredit new Discoveries, 'tis no matter how it follows. This Gentleman, you must know, Sir, useth to have his word taken among his admiring Neighbours, and so is not wont to be put to the trouble of proving: but I was so unmannerly as to expect it, choosing rather to see with mine own Eyes, than his infallible Spectacles. We can see better— saith the Disputer. How doth he know that? If Perspectives deceive us, though naked sense witness for them, Why may not his single Spectacles be as deceitful as they? These represent things bigger than they are to the unaided sight; and the Philosophical Glasses do but the same thing, in a higher degree of magnifying the Object. But we allow him the benefit of his single Spectacles, though he will not be so courteous to our Glasses, and confess his Reverend Experiment of the use of two, but are inquisitive about the Consequence. The Reason of which certainly must be, (if any be intended in it) that our Telescopes and Microscopes have a Glass at each end, which the Man of Sapience thinks answers the two pair of Spectacles, and therefore must render the Representation deceitful. If this Philosopher had 〈…〉 of those thoughts to the profitable doctrine of Optics, which he hath spent upon Genus and Species, we had ●ever heard of this Objection, which is as much a reason against the credit of all Perspective Glasses whatsoever, as the Philosophical ones he would discredit. And without more Optics than those of natural Understanding, he might, if it had pleased him, have known, that we see better through the two Glasses in Perspectives, than any single one; because they are so fashioned and ordered, that the visive rays are better gathered and united by them for the advantage of sight: But in the two Spectacles, the case is contrary. These things I suggested, and some others from the Dioptrics, in which this Sage Person was pleased then to conceal his Knowledge; and how great that was in these matters, will appear by the Learned Problem he proposed at this period of our Discourse, [Why we cannot see with two pair of Spepectacles better than with one ●●ngly? For, saith the Man of AXioms, Vis unita fortior?] A pleasant piece of Philosophy this; And I'll show the Disputer how strongly he infers from his Maxim, by another Question like it. Why cannot he write better with two Pens then with a single one, since Vis unita fortior? When he hath answered this Quaere, he hath resolved his own. I said in the Discourse, That the reason he gave why one would expect it should be so, is the reason why 'tis not; and this is plain enough to sense, from the confusion of Vision, which shows, that the rays are not united after the way requisite for the aiding the sight (as I just now intimated) and how that should be, I had here shown, but that I am ashamed to add more in earnest about a ●●●ve foolery. Upon this Discourse, the first Remark I shall make is, That Mr. Glanvill hath little or no insight into Optics, and is in a manner as ignorant in that profitable Science, as he represents his Adversary to be. It is something for a Man to be able to give an account how he spent his time, though about Genus and Species; rather then to appear to have idly passed it away, without acquiring any knowledge at all. The Solution of Mr. Cross' fallacy, if it were his) by that Interrogatory, Why cannot he write better with two Pens, then with a s●ngle one? is ridiculous, since there is no vis unita there: and in one sort of Tubes, though the Vitrum Sphaericè earum, dilatando radios per ipsum transmissos amplificat nota●●lit●r imaginem si in debitâ distantiâ constituatur post Sphaericè convexum.

How it is in Telescopes made up of all convex-Glass●s, the same Author shows there: and so doth Kepler in his Dioptrics. rays be united in the first convex-Glass, and brought to a Convergency, yet: must the Spherical Cavity of the next Glass dilate again, and dispose them sittingly to effect the expected vision in the Retina: and besides this, it is requisite that the Tube be so fitted unto the eye (not to speak of the fitting it differently according as the Medium is) as to exclude all other impressions and radiations, that Zucchius philos. oped. p●●t. ●. t●. 3. c. 7. s●ct. 5. p. 358. may divert and impede the sight, viz. Ad consulendum sufficienti determinationi potentiae per languidiorem & angustiorem impressionem à remotioribus, multum prodest, si ex forma instrumenti & ejus applicatione ad Oculum vel ex conditione loci è quo per instrumentum remotiora, & in minori amplitudine apparentia prospectamus, impediuntur radiationes aliunde intra oculum simul & semel diffusae, praesertim validae. As to what Mr. Cross is said to have argued against Telescopes, that the addition of one Glass to another must hinder rather than improve vision, because that the superadding of one pair of Spectacles to another, rather weakens than amends the sight. I must say, that whosoever understands the forming of an Argument cannot except against the form of that, nor do the Propositions cohere so ill together, as that one should be as it were for sense, and other, for convenience. All that excursion of our Virtuoso shows his Ignorance, not Mr. Cross'. 'Tis one thing to except against the form, another thing to except against the matter of a Syllogism. I confess there is reason enough for to do the latter; but now for the other procedure. I believe such a dispute was never heard of since the declining of Arcadia, as this was: If Mr. Cross did urge this otherwise then to try the Intellectuals of Mr. Glanvill, (concerning whose inability he might be well satisfied) there is no defence to be made for him, otherwise then that he was unacquainted with a sort of knowledge which is unnecessary in a Divine, and not expected from him; whose credit is better supported by those Qualifications which represent him as a man of godly Conversation, faithful and able in the discharge of his Gospel-Ministry. But that Mr. Glanvill as little understood the subject of a knowledge he pretends unto, it is manifest from hence; that he might easily have denied the Assertion of the Spectacles, that two pair did not impede, but amend the sight in some eyes that are very weak. I know a young Gentlewoman that hath two Cataracts breeding in her eyes, which reads and works with two pair of Spectacles, whereas she cannot with one pair. There is also an old Gentlewoman of my acquaintance who useth the same helps. I am ashamed to debate these fooleries (as our Virtuoso calls them,) but if Mr. Cross did call in question the integrity of the Telescopes, I shall assume the liberty of a digression about that Point, which perhaps may not seem unseasonable in this Age, and which will abate the pride, and evince the great ignorance of Mr. Glanvill. Either my Memory doth very much deceive me, or else the Lord Bacon did suspect these Telescopes, that they might impose upon our Senses: and I am sure Mr boil is in the same Error with Mr. Cross, for he complains that when He went about to examine those appearances in the Sun called Maculae, and Faculae solares, he could not make the least discovery Tentam.

Our Virtuosos have complained of an Iris in their Glasses, and gone about to correct that by Turning of them; but a friend of mine writes, that he imagines it was after that Eustachio Divini at Rome had given them an hint of it: and then they found it out. A little more modesty in Assertions of this kind would become our Wits, considering that affairs of this nature (it is the opinion of Archimedes, and refers to all Mechanismes) admit not demonstration. Cum neque visus, neque manus, neque instrument a per quae experiri oportet, satis habeant fidei ad exquisite am demonstrationem.— Archimed. in libro de Arena. I shall not so far engage in the controversy, as to repeat the Arguments and Replies on both sides. It seems strange, that the Telescopes should so magnify thirty, forty, or one hundred times objects on earth, and yet lessen those of the fixed Stars in Heaven, viz. Stellas primae magnitudinis, Caniculam, Scipio Claramont. de universo l. 9 c. xxi. etc. Jovem, Saturnum minores repraesentat multo, quam oculo libero appareant: & idem instrumentum stellas nusquam apparentes, ut Jovis Satellites justae magnitudinis repraesentat, & paulo minores repraesentato Jove, imo tantas facit, ut possint pius apparere▪ quam queant apparere stellae primae magnitudinis,— at quid? in Octava Sphaera stellas nihil apparentes magnas facit, Nebulosas scilicet, & Galaxiae formatrices.— This is granted all by Galileo to be true, but he solves by an imaginary irradiation, the fancy whereof he advanced upon some weak Experiments, most whereof he deserted himself, and the Vide Scip.

Thus the Objection in its full force is granted by all (except Sorsius deny it) only the cause of the Phaenomenon was not till Zucchius (if then) sufficiently explicated; Sure Zucchius phillip op●. part. 1. c. 1●. sect▪ 5. p 159, 200. I am that he in another place avows, that long Telescopes rightly made do not lessen Jupiter, but represent him greater than He appears to the naked Eye: insomuch that his Tube of 23 feet-long did represent Jupiter as big as the Moon is when at full, and looked upon without any Telescope: so that He says the Objection holds only in Telescopiis brevioribus, in quibus pariter evenit inspiciendo lucida inferiora. Besides, were there such certainty in the Telescopes, how comes it to pass that there is such a variety of opinions amongst those Observators, whose diligence can be as little suspected as their learning? Claramontius did set two persons to observe the Spots of the Sun, (both were inclined to Novelties) they were not 40 miles distant, yet did not their Schemes agree as to number, or situation. Nor is this a figment of that partial Peripatetic: any man that reads Ricciol Almag. nov▪ ● 3. c 3 Zucchius phillip opr. par 1. c 7. sect 8. p. 233.

Ricciolus, and Zucchius, will see that they cannot agree about the number, the motion, the situation, or so much as colour of them. The words of this last Writer are very remarkable in reference to Mr. Glanvill, and that certainty which he asserts unto the Telescopes, viz. Neque obstat discrepantia numeri, vel figurae macularum in observationibus plurium, circa idem tempus captatis: tum quia longiores Telescopii in ampliori disco plures exhibent, quae spectantem breviore Telescopio, angustiori disco latent: immo eodem Telescopio, ad exactam mensuram suae extensionis redacto, notabiles fiunt aliquae, ante inobservatae: & facillimum est in tali mensura minus exercitatos decipi; cum tam pauci ex observatoribus, nec nisi monente Scheinero, didicerint ad exacte consignandam Solis imaginem, & in ea maculas, per trajectionem radiorum Telescopio in planum directe oppositum, necessariam esse mutationem extensionis Tubi, eo not abiliter magis producto in hyeme, correpto in aestate: Tum quia sicut facilis est, ex allatis varietas in numero macularum, ita in terminatione, quae facilius mutari potest ex iisdem capitibus in illis, quae in pluribus observationibus consignantur, & ex modo consignandi. Less do they agree about the nature of them: one Joannes Jarde named them Astra Borbonia: and Malapertius, Mastrius, Rheita, do hold them to be Stars: of this opinion was Scheinerus once, but he afterwards assented to that of Galileo, Kepler, Bullialdus and Blancanus, that they were not Stars, but fuliginous exhalations arising out of the furnace of the Solar Globe, which he conceives to be a fire. Kircher and others are of the same judgement; but Ricciolus distrusts it, being not Vide Schottum ub● supra, p. 184. Ricciol. Almag. nov. l. 3. c. 3 P. 7. able to comprehend how fuliginous vapours should arise in such a number, so constantly, so permanently as to keep a motion about, or with the Sun, of about 27 days.

Galileo doth represent Saturn in one figure, Sch●●●●● in another▪ the former saith, that the oblong shape in Saturn ariseth from a defect in the Telescope, or Eye, that could not distinguish the Comites Saturni from the Planet itself▪ But Ricciolus and others descent from him in that point▪ and Christi●●●s Hugenius made observations about Saturn, such as neither Antonius de Rheita▪ nor Hevelius did ever see; and represents the ansulae of Saturn, differently from what Fontana and the Dantiscan Selenographer do write. The words of Hugenius I shall propose to Mr. glanvil's consideration, Expectamus ut sub finem Aprilis, si non antea, brachia Saturno renascantur, non curva illa, cujusmodi a Francisco Fontana, & Hevelio depicta cer●untur, sed secundùm lineam rectam utrinque prominentia, siquis melioris notae perspicillo intueatur.

Cum autem longiora etiam hisce Telescopia, utpote triginta & quadraginta pedum ab aliis fabricari dicantur, aliquid aut vitris vitii inesse, aut haec eadem non debita proportione mutuo respordere credibile est. Neque enim alius hucusque aciem eorum effugisset novus Saturni Satelles. Being to speak of Saturn, I must not forget Zucchius, who after thirty five years diligent observation with variety of the best Telescopes, represents this Planet differently from Zucchius philos. oped. part. 1. c. 17. sect ●. p. 00, 201. what any others write, viz. Assero Saturnum multorum annorum spatio figura passim oblonga, & in oppositione ad solemn, not abiliter majorem apparuisse, in apparentiae medio visum esse album illustre tumidum, aliquo modo ad rotunditatem vergens, accedentibus hinc inde ad illud duabus velut nigris notis, quas altum illustre, totam apparentiam ad apices terminans ita includit, ut ad apices illius multo sit crassius, ubi vero eas notas complectendo ad medium extenditur, gracilescat. Assertio est facti, in quo a multis jam, annis conveniunt accuratiores, ex variis Provinciis observatores longioribus Telescopiis instructi. Scio a prioribus vulgatum, tres a se stellas in loco Saturni spectatas, media multo majori, quae simul mutantes in coelo situm, a fixis aperte distinguerentur, & Saturni duobus Planetis minoribus stipati apparentium exhiberent, qui postea, illis a tali situ motis spectatus sit figura rotunda. Verum triginta quinque ut minimum, anni sunt, quibus figura semper oblonga, cum dispositione in assertione assignata, a me spectatus est pluries quotannis, pro vario ad Solem situ, acutioribus, minus acutis, cavis, convexisque lentibus ad oculum proxime in Telescopio adhibitis apparentia eadem, semper magis distincta, & majori, in oppositione ad solemn, etiamsi meliorem vitiorum ●laborationem in multo longioribus Telescopiis postremo D.

Concerning Jupiter, and his Satellites, and their number, Vide Schottum in Kirch. iter exstaticum coeleste p. 268, 269. etc. Ricciol. in Almag. nov. l. 7. sect. 1. p. 486. taking in the Urban Octavian Stars, I find a great variety, even when two men observed at the same time, as de Rheita and Gassendus: that both of them were in the right, cannot be said: which of them were in the wrong, I know not. In sum, the observations about Jupiter and his Attendants are so various, Aliter enim apparuerunt Simoni Mario, aliter Apelli, aliter Galileo, that Claramontius takes this advantage of it. Ego igitur argumentum ex ejusmodi diversitate alicio contra veritatem objecti, non contra observationum diligentiam, Scipio Claramonti●s de universo l. ●. c. 8. cum observatio ejusmodi non sit nisi pura per tubum transpectio, eaque defixa: two etiam viri perfectum instrumentum habebant, es●que id verisimile, cum in eam rem toti incumberent, instrumentum etiam exactum paravisse: oculorum etiam & visus acumen, cur demam Apelli & ejus in observando sociis, potius Galileo demerem, qui se fatetur oculum minus perfectum habere Neither are they better agreed about Mars and his Figure, the umbo or spot in him.

Interim te, amice Lector, provoco Spectatorem, bono & longiore Telescopio instructum, cujus Lens superior ad obtinendam siguram apparentiarum bene praecisam, juxta dicta, maxima ex parte contecta sit, modico ad medium aperto for a'mine. I am tired with the further prosecution of this subject; and therefore shall confine the rest of my discourse to the Observations about the Moon: the contemplation whereof, as it is more facile, so it hath been more pursued than any other of that kind. There is none of our Comical Wits doubt that it is a World, divided into Hills, Valleys, Seas, Lakes, Rivers, and even peopled as this Terraqueous Globe of ours But it is remarkable, that the use of the Telescope hath not convinced some, that the Moon hath an unequal surface, but that the Phaenomena of the spots may be solved by the conceit that some parts of it are more Diaphanous, some more opake. Who hath not heard how Scheiner looked on the Moon in an Eclipse, and did conceive it was fistulous, (at Berigardus C●●●. P. 〈◊〉 de Luna. id. ● least translucid in part) and so did transmit the light through several Cavities in some places, whilst others, not directly subject to the Sun, are obscure. They cannot agree whether the Spots of the Moon be more bright, or obscure in an Eclipse. The observations and descriptions of the Moon, made by Galileo, Scheiner, Fontana, Schottus upon Kircher, etc. are so defective, that we must repute them but as the first rudiments of an intended Science. And as for the descriptions of the Phases of the Moon, made by Langrenus and Hevelius, however there by many things in which they all agree: yet the Telescopes of Ricciolus (made by a Bavarian Artist) and of Franciscus Maria Grimaldi, either rectified the mistakes, or represented many Phaenomena different from those delineated by Galileo, Fontana, Torricellius, and Manzini, viz. Lunaris faciei partes omnes magnas, mediocres, ac Ricciolus Almag. nov. l. 4. c. 7. minimas singillatim Telescopio intuens Grimaldus, easque statim cum Langreni & Hevelii Schematibus comparans, deprehendit multa quidem egregie ab iis peracta, non pauca tamen superesse, quae aut addenda, aut quoad situm, magnitudinem, siguram, symmetriam, nigroris aut claritatis differentiam corrigenda forent. Such as reject the exact Sphericalness of the Moon, introduce Asperities and inequalities in the surface of it, which some explain by Mountains, Valleys, and Waters: but concerning the parts of the Moon, which might be Water, and which Land, our Observators did differ. Galileo Glailaeo sy●●m. cosmic. p. 131. edit. Lonain. Kepler. Astronom. Optic. c. 6. sect. 9 believes the spots or obscure parts to be water. Kepler held the contrary, that the bright parts were water, and pretends to demonstrate it out of Optics. though afterwards he changed his opinion for that of Galilaeo's, which is generally received. As to those asperities in the surface of the Moon, whether they extend to the Limbus, or utmost circumference, or no, is a doubt amongst them: Galileo Ricciolus Almag nov. l. 4. c. 8. qu 2. denies it; Kepler, Ricciolus, and others affirming it: and the latter gives this reason why they are less frequently observed there: Vera causa cur raro asperitas illa Limborum videatur, est partim imperfectio Telescopii, etc. Neither are they better satisfied about the Atmosphere of the Moon: that there is one, Galileo, Kircher. iter exstat. coelest. p 48. Ricciolus Almag. nov. l. 4. c ●. sect. 8. Kepler, Antonius Maria de Rheita, Kircher, Cysatus, Scheiner, with others do avow: and Langrenus saith, that we may observe it with a Telescope: eandem Tubo▪ specillis conspici affirmat Michael Florentius Langrenus. But others deny it as peremptorily. Interim mihi (faith Ricciolus) nondum quocunque Telescopio adhibito Ricciol. Almag. nov. l. 4. c. a. sect. 3. aer hic ita patuit, ut illum potius prope ac circa Lunam, quam in aere nostro, in quo & Halones siunt, cogar agnoscere. And Zucchius at large proveth this Corollary, Non elevantur Zucchius phillip optic part. 1. c. 17. sect. 9 p. 2●4. vi luminis Solis vapores e Luna, sicut elevantur ex Globo e terra & aqua integrato: Neque datur circa Lunam Sphaera vaporosa ulla, qualis circa dictum Globum deprehenditur. Having proceeded thus far, I shall take notice of some extravagant opinions that possess many of our Comical wits, and their Associates or Admirers, which are extended to the prejudice of Christianity, and the growth of Atheism in this Age, viz. That the resemblance betwixt the Moon and the Earth is such, that it is a Terraqueous Globe inhabited by men, and they hereupon concern themselves about their Progeny, Salvation, etc. I shall from hence take occasion to instruct those fantastical persons, that even Hevelius, who accommodated the Terrestrial Geography to the Lunar Globe, and seems to conclude that the illuminated part is earth, the darker is water: yet did it only because He knew no fitter comparison amongst sublunary bodies.— Non est autem quod quispiam ideo existimet Lunam ex ejusmodi sabulo, luto, aut lapide esse compositam, ut haec terra nostra, siquidem fortassis ex alia poterit constare materia, ab imaginatione nostra prorsus Joan. Hevelius Selenograph. p. 148. diversa, & modo adhuc incomprehensibili.— Minime etiam hasce Lunares aquas nostris● similes assero, sed quod nihil quicquam similius, propter magnam utrarumque affinitatem hic in terra habeamus, cum quo illas comparare valeamus. It was indiscreetly done of Kepler, Kircher, Hevelius, and such Writers to carry on the comparison so far, the resemblance betwixt the two Globes being so little as the most unprejudiced Ricciolus Almag. nov. l. 4 c. 7. p. 203. persons findit to be. Hevelius' perinde acsi Luna esset altera tellus, Geographica nostratis Telluris nomina in Lunam transtulit: licet quoad figuram, situm, symmetriam, etc. nulla fere sit Analogia inter utriusque superficiem. The truth whereof will further appear from those considerations which the inquisitive Zucchius after thirty five years use of all manner Zucchius▪ phillip oped. hart. a. c. 17. sect. 9 corol. 7. p. 266. of Telescopes at length fixed upon, viz. That the discrepancy of Parts in the illuminated Moon may be explained without attributing thereunto any variety of colours: yea, it ought to be so explained. The first part of which Assertion he proves thus: because in Opace bodies the difference of a greater and lesser Obliquity in their situation towards the body that shines upon them doth cause a divers manner of illustration. Thus the same wall, of one uniform colour, according as it is differently illuminated, seems in some parts to be white, in others pale, in others dark-coloured, and black: besides that, a greater or lesser asperity or inequality of the superficies may cause an intermixture of the enlightened and over-shadowed parts, and so create different appearances of light and opacity in their most observable parts. The second part He proves thus: because that the face of the Moon being looked on with a Tube of an extraordinary length, with Glasses excellently polished (such as He used for many years) appears all of it like a great Tract of Land covered over with Snow, which the Sun variously illuminates accordingly as the parts are differently framed and situated. Where there is any change of situation in the parts illuminated in reference to the body that irradiates them, then do such parts abate of their whiteness: and although they still continue in such a position that his beams may in some degree and manner reach them, yet by reason of the unequal surface of the Moon (in which some parts are more elevated than others) some parts are directly opposite to the Sun, others are glanced upon with an oblique ray, and this mixture of shades and brightness occasions those spots which we so talk of. Thus upon the libration of the body of Jupiter, the girdle, which otherwise seems remarkably black above the other adjacent parts of the Planet, becomes like unto the rest of the body in whiteness, and so disappears. As to the distinction of the Moon into Sea and Land, consisting of Mountains and Valleys; although the Analogy may Existimo materiam globi lunaris non constare terra & aqua Galilaeo system. cosmic p. 132. seem allowable by reason of the Asperities in the surface of the Moon, (which is a thing not to be denied: albeit that the calculation of the height of those more elevated parts are ridiculous, except the nature of the Cavities were better to be discovered, as Zucchius shows) yet the imagination Zucchias phillip oped. part. 1. c. 17. sect. 9 p 260, 261. of Seas and Lakes therein, or any thing of that Nature, except what borders upon the Peninsula deli●●orum in the Lunar Chart of Ricciolus, 'tis all an improbable fancy. For, that the more pale and obscure spots are not water, appears hence, that those spots keep the same Phasis or appearance for many days, though the Site of the Moon, both in respect of the Sun, and of us the Spectators, do vary much in that time: whereas when the Sun casts his beams upon Seas or great waters on Earth, the Phaenomena differ according as the Sun, or the beholder vary their station: And this alone might convince us, but that I find now in Zucchius, viz Similiter transitum successiv●m radiis Solis Zucchius' 〈◊〉 supra p. 263. ad fundum usque ad magnis maculis intra margines illustriores contentis praebent (ut diximus in apparentiis, pag. 239.) quod non evenit in liquido profundo instar aquae, ut in aquis e●perimur etiam in multa vicinitate illustratis, quando not abilem habent profunditatem: tum quia constantem inaequalitatem illustrationis exhibent in horizonte Lunari, & quidem, juxta dicta in Apparentiis (num. 3.) secundum magnam extensionem illustratam, intra reliquas partes nondum Solis radiis perfusas; imo aliquae, Soli proximiores, alias sequentes in eadem majori macula inumbrabant: hujusmodi autem convenire non possunt corpori Galileo pro●●●●eth, that in the Moon the●● is no ●●in; no clouds there thicken ●●e a●●.

I must confess I think these reasons convincing to any persons not prepossessed; and they are much more enforced by him with a discourse concerning exhalations and an Atmosphere about the Moon, which he denies absolutely: yet considering the proportion of the imaginary Waters to the Land in the Moon, and the heat and continuance of the Sunne-beams thereupon, common reason would tell us▪ that the vaporous exhalatious would proportionably exceed those about the Earth here, and produce an Atmosphere that should be observable, whereas the most accurate inspection at most opportune times with the best Telescopes could not satisfy Zucchius, that there was any such thing at all. Kepler (and his Master Moestlinus) did believe that the Kepler Astronom. Optic▪ c. 6. sect. 9 Moon was a World consisting of Sea and Land, making up one entire Globe, as the Earth does; and that the Mountains there were much higher and bigger comparatively than those of the Earth: and adds by way of jocundry, that since the Men and other Animals commonly Ga●ilaeo system.

In fine, he thinks it no absurd opinion of the Gentiles, that made the Moon a kind of Purgatory for departed Souls. Upon the most serious consideration of all circumstances, whereunto I could ever engage my thoughts; when I reflected upon the great difference betwixt the Days here and there; the different influence which the Sun must have here and there through the Diversity of his Aspects, (whereupon depend Terrestrial productions) that there is no rain, no clouds there; no Atmosphere (like ours) proportioned to such respiration and life: no intermixture of earth and water: no innate diversity of colours, which occasion the Phaenomena that perplex our overcurious Mortals: and that all the Inquiries hitherto made, have so little of evidence, that 'tis more clear that the Moon is a Cheese, (not fat, for than it would melt) oddly figured and made with Asperities in its Superficies▪ and perhaps a little vinnyed in some parts▪ then an Earth resembling ours: I could not but condemn those our Comical and Atheistical Wits, who use so little of modesty or scrupulousness in their discourses about this so uncertain subject. They are men of so little reading and inquisitiveness (whatever they pretend unto; as if this Nation produced no persons equal to them for Learning and Abilities) that they never examined these debates; but the opinions which they take up and transform into Assertions, are only the raillery or casual and imperfect pieces of conversation betwixt more intelligent persons, or some Coffee house-talk, which they confidently obtrude and impose upon speculative or more considerate Gentlemen, and render themselves insupportable in any Society. A young Gentleman, a friend of mine, who was not a little valued in the world, who was no stranger to the Mathematics, and whose wit and learning far transcended any thing I can observe in a droll and Comediantes of these times, entertained me with a discourse once of this nature; Having spoken of the Celestial Phaenomena, how differently they were represented by sundry men, he was more prone to suspect their dioptrick Tubes, than their integrity: He thought Tuius lentibus duabus constans dici potest o●uius mere artifi●i●●us 〈◊〉 ●ne● Ro●. Ursi●. l 2. c. ●7 quem vide ●b. a c. 23. usque ad c. 30. our Eyes were Telescopes of God Almighty's making, and the model by which the others were regulated and amended: and that any man who regarded the daily Occurrents in vision, could never believe it possible▪ that any certainty could be derived from Telescopes, about such Phaenomena as we could employ only one sense about, and that not in a due distance, and with such circumstances as legitimate the judgement thereof: That we were to look through their different mediums (granting that our Air makes but one Diaphanum) and those not contrived dioptrically, that we know, and that since every medium, thicker or thinner, (besides the intercurrencies of irregular and unknown particles, like to moats in and upon Tam ra●it●s quam densitas potest esse causa r●fractionis. Me●senn▪ a Glass) did cause a different Refraction, and that neither the constitution of our Atmosphere (as not proportionate to our sensible inquiries) and air, nor the intermundial Aether, nor the Sphaera vaporosa of the Planets could ever be accurately and satisfactorily searched into; no man could particularly know what he beheld, and deduce with prudence any theorems and conclusions from such infirm hypotheses. He added, that our senses and the daily objects we converse with on earth, did prejudicated rather than qualify us for these speculations: that we might easily observe what mistakes arise from the contemplation of resemblances: that similitudes, though very slender, engage the unwary, (and some that are cautious too) to conclude an identity in objects: that it would be impossible for any man without the aid of a nearer approach, and even of his other senses, to conclude whether a stick lying part in, part out of the water were straight or crooked▪ by reason of the refraction in the different mediums of Air and Water: and that a Glow-worm, or an Indian fire-Fly would create strange disputes and contests amongst mankind, had they no other helps to discover the Phaenomenon then a Telescope, magnifying the object and its parts thirty, forty, or one hundred times. He admired that saying of Aristotle, 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉: Arist meteor. ●▪ 〈◊〉 4. sect. 2. These are the words, and this the judgement of Galileo Syst.

That the appearance of an Earth, did not infer the inhabitation of men, much less Animals and Plants like ours: that our own Geography might undeceive us herein, some parts of this Globe being not peopled, and the animals, and plants, and nature of the soil, differing so much from our European productions, as we could not have conceived, had not our Eyes and authentic testimonies gained us to a belief of it. That the most clear Eyes have in this case a kind of a suffusion, and the most unbiased persons their Intellectuals prejudicated, and had no reason to condemn the opinion of that Peasant, who imaginer the Grandeur of Rome to be like unto his Village, or the Scot who represented London to be such another town as Edinburgh.

Having said these things, that great young man, (who died before that Ignorance and the Virtuosos grew prevalent) presented me with the works of Marcus Aurelius Antoninus, published by D. Meric Casaubon, opening it at that place where that understanding Emperor acknowledgeth it to have been the special favour of the Gods, that he never troubled himself about these Meteorologies and extravagant speculations, whereunto nothing humane can reach: He added, that in these kind of speculations he knew enough that was secured from superstition, that for a man to desert those Studies which qualify him for a sociable life, and were of importance to the preservation of the Government and Country he lived in, this was a kind of salvagenesse, had more of the A●chorete, then of Civil Prudence, and was to be encouraged in a Cloister, or in the deserts of Thebais, then to be made a practice among wise Statesmen. I have sometimes entertained myself with the remembrance of this Gentleman, and guessed how he would have sported ut that passage of Mr. Glanvill, in his Scepsis Scientifica, where he compliments the R.

This is a most extraordinary Flourish: Yet I find the Rhetoric defective in the suiting of the Antitheses and Antapodoses: but I shall not take notice of that fault now, it is so general in our Comical Wits. I shall now quit my Digression, and resume the controversy betwixt the two Disputants. Mr. Glanvill, for the credit of those Dioptrick Glasses, told Mr. Cross, That he might try them upon Objects near, and easily visible, by the unassisted sight; and if he made trial, he would find they altered the Objects in nothing but their proportions, which are represented larger for the advantage of vision in things small and remote; and we have all the like reasons to distrust our Eyes, as these Glasses (for their informations are the same in all things, but the mentioned difference) and there is no man such a fool as not to make allowance for that.— I see Mr. Glanvill is not only ignorant of the Optics, but altogether unacquainted with Telescopes: for first there are some made by Mr Smithwick (a very ingenious and worthy man) Duobus vitiis convexis instructo Telescopio, habetur simul & semel objecti medoocris, vel multarum partium grandioris repraesentatio, sed inversa: si debite addatur tertium convexum, multiplicatis adhuc refractionibus, una unius obtinetur apparentia, & in situ conformis Objecto. Zucchius phillip oped. part. ●. c. 17 sect. 2. p. 180. which represent the Phases of the Moon very well, and yet invert all Objects, but that is no default or impediment where the thing looked on is round. These convex Telescopes a●ter the Object in some thing else besides their proportions: nor doth any such thing happen in a well-disposed Eye upon vision Secondly, he might have known this further difference betwixt an un-assisted sight, and what is performed by the best and longest Telescopes abo●t ordinary Objects, that the Dioptrick Tubes do represent the light and colours of bodies more d●lute and remiss than they appear to Zucchius ubi supra p. ●81. the naked Eye. Per Telescopia, praesertim longiora, objecta spectantur luce & colore dilutiora, quam libero oculo. This is granted by Zucchius and others; and the reason is given by Zucchius, because that so great an expansion o● amplification of the Object, and 〈◊〉 of its Expansion●m repraesentativorum aequ●valere remissioni, & densationem corum intensioni, & utramque non à medio, sed a propria conditione propagationis radiorum pendere. id ib.

Zucchius phillip oped. part 1 c. 17. sect. 6 p. 204 parts one from the other, is equivalent to a remission of those qualities therein. But to show Mr. Glanvill a little more of his ignorance in Telescopes, I shall show him some further differences betwixt the naked sight, and what is performed by those Glasses. For some of them represent some Objects greater than they appear to the naked eye: Some (in the shorter Tubes) are represented no bigger, or rather less than they otherwise seem: Some Objects in the longer Telescopes are magnified indeed, but nothing so much as other Objects are by the same Glasses. The Experiments are obvious: place a candle in the dark at some considerable distance, and the flame will appear round and encompassed with rays: then take a short Telescope fitly made and placed, and look through it, and you will see the irradiation taken off, and the flame represented as oblong, not round, and rather seemingly less than greater than it appeared before to the naked Eye. Then turn your eye unto any coloured Object, and take notice how big it seems: assume the same Telescope, and you shall find that to be magnified above what it seemed to the naked eye by much. After this, take a long Telescope, and view the aforesaid candle through that; and at the same distance view some other coloured Object, and you shall see that this last Telescope will represent both Objects much magnified; but the Candle less of the two by far. But I shall add further, that it is not to be doubted but that the Telescopes of Galileo, Scheiner, Rheita, Gassendus, Grimaldi, Eustachio Divini, Hevelius, Hugenius, Ricciolus, and Zucchius, were good in their kind, and that they did represent Objects as truly here on earth, as Si Lunares discos, post tot inspectores, & inspectiones▪ publicatos videas, neque▪ numero, neque conformatione si●i correspondent: quam multae partes vel prae aliis circumpositis illustriores interjectae & saa multo mino●i illustrationis exhibitione illas interrumpentes, aliquos latuerunt, & in angustioribus, vel minus accuratè expressis. Discis omissae, q●ae verè internoscibiles sunt in luna, & ab alii● consignantur? quantum totius Disci lunaris terminatio▪ & insigniorum in ea partium, variata? Zucchius phillip oped. part. 1. c. 17. sect 8. p 2●3. any could; yet when they come to be applied to the Celestial Phaenomena, what difference is there in their Observations? How do they complain either of the default of the Telescopes, or want of care or skill, each in the other? Simon Marius boasts of his accurateness: Scheiner in his Apelles tells us, Observationes omnes factae sunt summo studio coelo serenissimo, semper cum observatum est, & obscurissimo, plerumque Vide Scipion. Claramont. de Univers. l. 3. c. 8. in absentia videlicet Lunae: talis vero variis & excellentissimis, quorum uno meliorem adhuc ad stellas non vidi. But enough may be collected to this purpose out of the foregoing discourse, so that I need not repeat it over again: out of all which as I would not be understood totally to discredit the use of Telescopes in celestial discoveries, (I do not deny but some things and some motions are observed by them, which a naked Eye cannot discern; but this knowledge arrives to a slender degree of certainty, when the Phaenomena come to be particularly explicated; and theorems or assertions framed thence) so I would not have them too much relied on, nor men be too confident in principles and Conclusions which have no surer Foundation than those probabilities: and I do herein join with Claramontius in that Epiphonema, In tanta diversitate, quid certi ex tubo Optico habemus? If I must suspect the skill or accurateness of Galileo, Scheiner, Gassendus, Hevelius, Fontana, Ricciolus, and Zucchius, and such like; pardon me, if I know not whom to believe. I have been the more large in this Point because of the insolence with which Mr. Glanvill persecutes that Reverend, and otherwise learned person, whom he represents to the world as He pleaseth, and accordingly treats him with that contempt and scorn which is less allowable towards a Divine, and such a one as is, and always hath been in that Country very much esteemed by several honourable Families, as well as others. However God hath so providentially ordered the dispute, thereby to check the pride of our Virtuoso, that The Man of Words cannot triumph over the Man of Axioms. And if it be true, that our Aristotelean was amazed at the hard words of Dioptrick Tubes, etc. as if there had been Magic in them: I doubt not to Justify Him in it; for the insolent Virtuoso made use of them, not as became a knowing person, but as Conjurers use strange terms, and of an uncouth sound, though perhaps really Hebrew, Latin, or Arabic. Besides all this, perhaps Mr. Cross seems to have been offended at something in that mixed discourse or dispute, that might derogate from the Authority of the Scripture: many sayings are not innocent, but as they are worded or uttered. To say the Scripture was written to men's fancies is an expression very unwary in a Divine: although a convenient interpretation may excuse it. To say it is not written according to vulgar Methods may so be spoken, that the action may render the words culpable. And in another Age they might have passed better than now, when men are prone to vilify the Scripture, especially the little Wits. I perceive Mr. Sprat is not overtender of the dignity of the Scripture: for although there be an ancient Canon of the Church against the applying the Sacred Word of God ad scurrilia & adulatoria (which Canon is authorised even by the Council of Trent) yet doth he encourage men to apply it to ordinary Raillery. The Wit that may be borrowed from the Bible is magnificent, Plus ultra Page 4 4. and as all the other Treasures of knowledge it contains, inexhaustible. This may be used and allowed without any danger of profaneness. The Ancient Heathens did the same. They made their Divine Ceremonies, the chief subjects of their fancies: But this practice of theirs was the ruin of their Religion, as any man may judge who sees what use Clemens ●lexand●inus and Lictantius make of it against Paganism. And the Greeks thought so when they punished on●, 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 by that means their Religions had a more awful impression, became more popular, and lasted longer in force then else they would have done, And why may not Christianity admit the same thing, if it be practised with Sobriety and Reverence. What irreligion can there be in applying some Scripture-expressions to Natural things? Why are not the one rather exalted and purified, than the other defiled by such Applications?— The Case is clear Gentlemen, Hath not the Lord said, What hast thou to do to take my words into thy mouth since thou hatest to be reform? Besides, methinks our Divine might have remembered the feast of Belshazzar, and the resentment that the Lord expressed upon the applying of the consecrated vessels to the serving in a festival banquet, though to a Prince. He might have called to mind the hand-writing upon the wall, and very probably have inferred with himself, that if God was so concerned at the misapplication and abuse of those Temple-Vessels, he would much more severely interess himself where that Word of his, which he hath so many ways hallowed and recommended to our Veneration, is abused to raillery: This Humour is no part of the words or works in which the Man of God is to be perfected by reading of the Holy Scripture. I fear the great Judge will one day say unto these Drolls, Ye are weighed in the balance, and found too light. To conclude, the generality of Raillery amounts to no more but so many idle words, and they become doubly criminal by being profane. Of the Antiquity and Use of Chemical Physic. CHymistry hath indeed a pretence of the great Hermes for Plus ultra, Page▪ c ●1. its Author, (how truly I will not dispute.) From him 'tis said to have come to the Egyptians, and from them to the Arabians; Among these it was infinitely mingled with vanity and superstitious devices: but it doth not appear at all in use with Aristotle and his Sectators: Nor doth it appear that the Grecians, or the disputing Ages, were conversant in these useful and luciferous Processes.— Our Virtuoso is not willing to dispute whether Hermes were the Author of Chemistry, or not: It had become one that is encharged with the Cure of Souls very well, to have declined all these other disputes, as being remote from those Studies, by which he ought to qualify himself for a be fitting discharge of the Ministry. But to tell him further, what I am sure he is ignorant of, the Egyptians did never attribute to Hermes the Invention of Physic, or any part of it, but to Apis and Aesculapius; and as for that Chemistry which they practised, which consisted in melting down and improving of Metals, or making of Gold: Chemiaes nomine olim haud 〈◊〉 ●vi● aliud significatum▪ quam 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 aut vero 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 ●●am quae viliorum metallorum la pdumque in melius commutationem pollicetur Ne q●i dem legere est, vel medicamentis praeparandis operam aliquam impendisse primos Chemiae professores. Con●●ng. de Med. Herm. c. 3. p. 15. the Egyptians did never reckon the discovery of that Art amongst the praises of their Hermes, though they were very forward to magnify him, and to ascribe unto him a great many Eulogies. Nay, when they do recount the Authors of their Chemistry, though they do not agree about them, yet there is none that transfers that honour upon this Trismegistus. But whether Aesculapius, or the wicked Angels, (to both which the Invention is attributed) were the discoverers of Chemistry, I think I may allow the Egyptians to have been the first Practisers of it, and that there wanted not those who did mention Hermes amongst them that used that Art, and were esteemed Philosophers. Nor is the Egyptian Chemistry of any great Antiquity, there being no mention of it in any Greek or Latin Writer, till almost the Vide Coming. c. 3 p. 28. fourth Century after Christ. Neither is the name only of Chemia or Chemistry of so modern a date: but there is not any record of any book In the time of Constantine A. D. 320.

P 〈…〉. written, or work performed, that imports any such thing. Yet have the Alchemists (it is true) pretended to a greater Antiquity, entitling several spurious books to Hermes, Moses, (and Miriam his Sister) Democritus, Plato, Aristotle; and made as if their Art were intimated in the fable of the Golden Fleece, the Hesperian Orchards, and the Song of Solomon. In which I cannot but take notice of the different procedure of those Chemists, and our Experimental Philosophers: the one attributed all glorious discoveries to the Ancients, their Predecessors; these will not allow them those praises which indisputably belong unto them. But however, that I may grant our Virtuoso, that Chemistry did flourish in Egypt in such manner and at such time, as I have declared out of Conringius, (to whom I refer the inquisitive Reader) yet I must not gratify him with this other concession, that from them it came to the Arabians, the followers of Aristotle not being at all acquainted with it, nor the Grecians, or those disputing Ages, being at all conversant with it. For it is made evident by Conringius, (c. 26. p, 368.) that it passed from the Egyptians to the Greeks. There are of Greek Writers, Zosimus▪ Panopolita, Olympiodorus, Stephanus, Synesius, Michael Several of these Greek Writers were seen by Salmasius in the King of France his Library, and by Reynesius, (vide var. lection l. 2. c. 5 p. 5●.) who transcribes this passage ●s the Conclusion of one of them. 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 lest any one should think that by 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 were meant our Wits, and Poets, and inventors.

This Geber is the most ancient of Arabian Alchemists, their Idol, and styled Magister Magistrorum. I am not ignorant that Conradus Gesnerus (in praef. ad Evon.) and some others Geberus quem volunt circa annum Portus virginei sexcentissimum in vivis fuisse Libav exam. censur.

But though the Greeks were not free of the Metallurgical part of Chemistry, yet did they not prepare any Medicines Chemically (that I know of,) except it were the Alcalisate Salts, and Ecchylomata, or Juices form into Extracts, and Oils drawn per descensum. This seems manifest in that Oribasius, Aetius, Paulus Aegineta, Alexander Trachcanius, PAULUS & JOANNES Jatrosophistae of Alexandria, Simeon Sethus, Actuarius, Nonus, Conringius c. 26. p 370. Gesner, in praesat. ad Euonym. and others mention no such Medicaments: no, nor Michael Psellus, though he writ a peculiar Tract about Chemistry. Neither hath Nicolaus Myrepsus (though a modern Grecian) any Chemical Preparation. The Arabians seem the first that ever accommodated Chemistry in an eminent manner to Physic; if it be true, as Libavius imagines; that Abulchasis did live in the time of Muhavia the Saracen, that settled their Empire at Damascus Anno Dom▪ 660. Chemistry then seems to have been regulated into an Art; He writ a Book of Physic called Servitor, Libav in exam. sent. Paris. which principally treats of Medicines Chemically prepared, and useth the terms of reverberation, calcination, coagulation, distillation per ascensum & descensum: and many such like expressions, together with Processes purely Chemical. It was then that Alchemy was called Perfectum Magisterium; and that which we call Oil of Bricks, did bear the name of Oleum Sapientiae & Perfecti Magisterii. So Avicenna speaks not only of Rose-water distilled: but of Mercury and Arsenic sublimed: after him Joannes Mesues shows how to make several Chemical Conring. ubi supra, p 374. Oils, as of Amber, Wheat, Oleum Philosophorum, etc. Neither is it to be doubted, but that there were an infinite number of Chemical Processes latent in the hands of particular Artists, since Joannes Mesues refers us unto them, viz. de quibus loquuntur, qui quae Vid. Conring. ubi supra. sunt occulta in rebus manifestant & detegunt. Hos quoque aggredere rei hujus cupidus tam famosae apud illos.

Nor were they only followers of the PERIPATETICS, but I find the Chemists that did precede Paracelsus to be accounted Hippocratical Physicians: witness this passage in Caspar Bravo, who inquired more into them than I have had leisure to do.

With this agrees that passage of Conringius de Med. Herm. c. 28.

He vilified Logic as that which caused endless disputes, and darkened rather then discovered Nature: He calls it matrem odii, rixarum & litium; He prohibited the reading of other good and Ancient Authors. He seemed to be of no Religion; and if for any, it was to be without Metaphysics, without the mixture of Glosses and Interpretations, Solum textum Scripturae legendum, interpretationem nullam adhibendam. He calls upon all Universities and Countries to resort unto him, to follow him and his new discoveries, his real Philosophy, his Essential Anatomies, all other performances being but empty and verbose.

Hereby any one may see that He was as conceited of himself, and as great a contemner of all ancient Learning, and of Aristotle, and Galen, etc. as some of the Virtuosos: and as ignorant of Latin and other tongues; and as false and imperfect in his relations; as variable in his hypotheses, as if he held nothing but with the power of revoking it, which is a great qualification of a modern Philosopher. He was not for the particular methods in vogue, but for a general Enquiry into the Experiments of old Women, Mountebanks, Hangmen, Husbandmen, etc. He could make use of the writings and inventions of others, concealing their 〈◊〉, and 〈…〉 as becomes a modish Experimentator. To evince this last assertion, I shall set down some passages of Crato, and others, to show that the disputing Ages were not so ignorant of Chemistry as Mr. Glanvill pretends. Crato in a Letter to Erastus writes thus; Remedia quibus aliquando usus esse dicitur, Erastus' part. 4. p. 300. non illius esse ex eo certus sum, quod librum vidi ante ducentos fere annos a Monacho quodam Ulmae scriptum, in quo eadem medicamenta, quae ille frustillatim, nunc in has nunc in illas chartas sparsit, perspicue sunt scripta.— And elsewhere, P●ae● ad Exercit.

Remedia nostra ex Chymicorum Schola prodiisse non dubito fateri: & quoniam Chymica ars infinitis erroribus scatere visa est, illud quoque Augiae stabulum repurgandi laborem sumpsimus: in quo felicius mihi versari licuit, quod ob ineunte aetate magnae Artis studio captus summa diligentia sub excellentissimis praeceptoribus Arti huic studuerim.

Haec ibi Paracelsus. Neque vero falsa scribere est putandus, quandoquidem seculum istum & exercitiis Chymicis & voluminibus scatuit, cum jam plures tractatus typis publicis sint impressi, nihilominus cernimus, subinde ex tenebris prodire plures, ita ut ne Thesauri quidem multi videantur sufficere cupiendis, nec Theatra. His followers confess, that he borrowed much out of Basilius Valentinus, and more out of Isaacus Hollandus, as Penottus declares, Cum incidissem in Isaaci librum de opere vegetabili, De dena●▪ medic. reperi de verbo ad verbum doctrinam de tribus principiis, & de separatione quatuor Elementorum ab eo desumptam, Unde constat illum praecipua sua Opera suffuratum fuisse, atque hinc inde expiscatum: ut de gradationibus medicinarum ab Arnoldo, Vide Conring. de med.

Archidoxa a Raymundo Lullio ex sua Arte operativa: de Arcanis a Rupescissa; nihil prorsus a seipso praeter convitia: & maledicta: a Trithemio varia.— The same is confessed by Quercetan somewhere as I remember, and he himself intimates it by adding to many preparations the words, Ex nostra correctione, ex mea emendatione. Out of all which it is evident, that neither the Grecians, nor the disputing Ages were so ignorant of Chemistry, as Mr. Glanvill asserts; as it is certain that the Arabians as well as the Grecians were disputers and followers of Aristotle and Galen, and that particularly Albertus' Magnus and Roger Bacon were Schoolmen. Nor can any man doubt the same of those other Bishops and Monks, who knows with what perfect Veneration, in those days Aristotle was regarded. How useful and how luciferous their Processes were, it is not for Mr. Glanvill to judge, who is ignorant of them: but any one will allow them, both the one and the other, recommmendation, who considers that their Chemical Processes which passed amongst them gave occasion to all, and make a great part of the improvements in Chemistry, in Dioptrics and other Subjects, wherein our Virtuosos pride themselves. Particularly as to Chemistry, it is as clear that the disputing Ages and followers of Aristotle were acquainted with it, and eminent for it, as that there were Monks and Schoolmen. Those men whom Mr. Glanvill so explodes, and with whom the Historian disports himself, had of late years before Paracelsus, in a manner, solely the knowledge of this Art by which Nature is unwound, etc. This Sennertus De Cons. Chym. c. 3. granteth. Proximis seculis fere inter Monachos latuit Chymia, quorum non pauci illud, quo abundabant, otium post sacras meditationes & orationes, arti huic praestantissimae honeste tribuerunt: inter quos fuerunt Raymundus Lullius, Albertus Magnus, Joannes de Rupescissa, Savanarola, Morienus, Rogerius, Trithemius, & Frater Basilius Valentinus: quorum scripta multa hoc seculo in lucem edita sunt, & multa adhuc manuscripta passim latent. I hope there is no exception against Sennertus, how partial soever Erastus or Crato may seem. And to affront our Virtuoso a little more, it was a follower of Aristotle, and those Disputers, a pitiful School-Divine that discovered the making of Gunpowder, which single invention outdoes all that our Collegiates boast of. In the year 1354. Bertholdus Schwarz a Benedictine Monk discovered it, and I dare warrant him in those days no enemy to the man of Stagyra, the Idol of disputers; A very ancient Manuscript gives him this Character.

In the time of Julianus and Valentinianus Emperors lived Aetius Amidenus; he and Nicolaus Myrepsus (who is indeed later than Mesue) do mention the distillation of Oils per descensum, as Gesner shows; and Vossius together with Conringius avow— Nicolaus Myrepsus (or Praepositus)— in quo illud miror nullam ab eo aquarum oleorumve Chymisticis instrumentis paratorum mentionem fieri.

Concerning fixed and Alcalisate Salts, the Chemists and Chemical Physicians make a great noise: and undoubtedly the Invention is very extraordinary, and their use very singugular in Medicine. Yet both See the antiquity of the use of Alcalisate and other Salts by the Ancients, largely proved by M. Ru●andus progymn. alchym. qu. 14, 15. Vide Galen. de Theriaca sub finem, & Pharmacop.

Besides, I observe out of Gunterus Bellichius, that Aristotle was not ignorant of it. Aristoteles auctor est, Umbros cinerem harundinis & junci decoquere aqua solitos, donec exiguum superesset humoris: qui ubi refrixisset, salis copiam fecerit, lib. 2. meteor. cap. 3. Hoc se apud Theophrastum invenire Plinius testatur, lib. 31. cap. 7. Idemque non harundinei tantum juncique salis meminit, sed colurni insuper, & querni. Amborum autoritate (nam de Theophracto nihil mihi constat) Chymicorum castigabitur temeritas, quae suis inventis salem cineritum an●●merare ausa est. The preparation of Saltpetre with Sulphur, in order to the making of what the Chemical Physicians call Sal prunellae, was known to Hypocrates, and others of the ancients, and they used it in Squinonsyes in Gargarisms for the tongue and throat.

Neither is the way of subliming Flowers of Benzoin, any thing else then the imitation of that way which the Ancients had of condensing Soot. So Bellichius informs me, Fuligo, Id ib. l. 1. c. 2. p. 31. definiente Scaligero, cujusque rei pinguis crematilis pars est, ac demum aliarum rerum fumus condensatus, Exerc. 56. Modus conficiendae ejus, siquid artificii subest, apud Dioscoriden extat, lib. 1. c. 85, 86, 94, 97. imitatio apud Beguinum, quando Benzoinum defloravit, l. 2. c. 18. It may perhaps be granted by most intelligent persons, that the making of Extracts, and fixed Salts, and such instances of Vegetables being prepared as I have given, and the glory of those inventions cannot justly be denied unto those disputing Ages; but that the preparation of Minerals, and the medicinal use of them inwardly, is a discovery the ancient times were not acquainted with. And this is the judgement of many learned men. But in refutation of it, seeing that the inward use of Antimony, as it is several ways prepared, refers to Basilius Valentinus, and before his days; since that, sundry preparations of Mercury are more ancient than the humour of novelism; since Paracelsus, Hartman, Crollius did but publish the processes of Aristoteleans, Avicennists, and such like Monks and Physicians; all that our Virtuoso can derive from this Plea is, that the Arabians, adherents to the old Philosophy and their followers, did improve the extent of Chemistry, and added thereunto as they did in the other practice of Physic, the use of Rhubarb, Cassia, Manna, Tamarinds, and other benign medicines: and this demonstrates that Philosophy and those notions not to be so sterile, as they are represented in comparison of the Fecundity of the Cartesian Principles, from whence Physic hath received little (if any) benefit or advantage. But to raise this Enquiry beyond the times of the Saracen Empire, it is manifest out of Pliny, that mineral-waters were drunk in those ancient times: and that the Stomoma or rust of iron, as also that drinks in which Iron was quenched, was given in the time of Dioscorides and Galen. That Brimstone was given inwardly Diosc. l. 5. ●. 53. Galen. l. 1. de cuporist. c. 17. by Hypocrates to asthmatick persons. That the Squamma aeris was given inwardly, as a purge and vomit by Hippocrares, Hippocr. de vict. in morb. acut. Vide Doring. de medicina, p. 217. Ruland▪ progymn. qu. 20. Brassavol. de me●. purge. p. 177. ●oterius. Pharmacop. Spagir, l. 2. c 6. Galen, Dioscorides and Gelsus: and the Experiment happily tried by Brassavolus, that great Experimentator again of later years. So the giving of Sandaracha, or Orpiment inwardly for old coughs; and the suffiment made out of it, are recorded by Dioscorides: the trochises of it recommended anew by Mesue, and the more modern trials in Riverius. Even Chalcitis is an ingredient in the ancient Treacle of Andromachus. I shall conclude all with the passage of Doringius in the place already cited, Praeter Sandarachum Isidorus, Athenaeus, Idius, Eubulus, Heras, Gemellus, Agathius, Nicostratus, Doring. de medic. & med. p. ●19.

Out of which passages any Reader will gules what Precedent later Authors had out of the more remote Ancients for the giving minerals inwardly; and if we are just to the Arabians and their followers, we shall scarcely allow them any further honour, then to have found out some new ways to serve up o●d dishes. I shall add, that in Egypt, at such time as the repute of the Egyptian Priests, and their fantastical Philosophy had given way to the followers of Hypocrates, Aristotle, Herophilus, and others, that introduced the Grecian Learning there, that is, in, and somewhat before the days of Dioclesian, the Egyptians were Masters of that Secret of making Gold, which our inquisitive Moderns have so vainly sought after. Before that Age there is no mention of it, and then it is said they had such knowledge of the Art of making Gold, that thereby they were enriched and impowered to make War upon the Romans; and being overcome by the Emperor Dioclesian, he burned all the books which they had, containing the Mysteries of that Art, to prevent any future commotions of that Nature. So Suidas in the word 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉▪ 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉. And in the word 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 he says, 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉.

And Paulus Diaconus in tho life of Diocletian: Neither doth Libavius or Rolfincius elevate the authority thereof, though he mention the passage of Suidas. And to give a further colour unto this relation, I am informed that Aeneas Gazaeus, who lived in the latter end of the fifth Century, when Zeno and Anastasius were Emperors, treating of the Resurrection, hath this passage, 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉. But these Narrations are rejected by such as deny that other metals may be transmuted into Gold: It is replied by Erastus, that either those Egyptian books contained nothing but the Art of melting down of metals, and separating the latent Gold therefrom: or that Suidas being a late writer, living but 500 years ago, about 800 years or more after Diocletian, might have been imposed upon by the Chemists of those times (in Greece, and during the disputing Ages! mark that Mr. Glanvill) Conring de med. Herm. c. 3 p. 23. who even then might have feigned some such stories as that (and the Allegorising of the Golden Fleece) just as they have within the last Centuries counterfeited the Works of Moses and Solomon, and entitle them unto their Fictions. There are an infinity of stories in Suidas, which render his Assertions suspected: and in this he hath not the countenance of any ancient Writer to second him. It seems strange, that the Romans having so long ruled in Egypt absolutely, and their Governors, they not being to be supposed free from all desires of gain, how they should never apprehend the Artifice, nor have the least mention of it in their Writers (Greek or Latin) till the end of the fourth Century: and that so remarkable a passage as this is should be omitted by those ancient Writers, who relate both the war and actings of Diocletian Id ib p. 22. after his victory. As for that saying of Aenaeas Gazaeus, it is replied that he speaks by hear-say, rather than certain knowledge of the operation: that there have not wanted many learned persons, who have with a great deal of confidence, De plant. resuscit. vide Bellich. Thessaly, ●ed. v. c. 7. Rolfinc. art. chym. l. 6. c. 3. & l. 7. c. 19 illustrated the Resurrection by contemplations of the Phoenix, and of the forms of Plants resuscitated in their several Salts, as if both were realities: yet is there no such thing as either the one or the other. Out of all which it is evident that Chemistry was a practice known and in use among the Sectators of Aristotle: and that the Grecian and disputing Ages were not unacquainted with those Processes, though these latter times have been more various and inquisitive, and have reduced that Art into better Method, and enlarged the Practice of Physic, with an infinity of Medicines: and indeed we must confess ourselves very much obliged by the labours of ingenious Chemists, and that they have afforded multitudes of Experiments, such as contribute to the delight of all Philosophical heads, and to the Cure of many that being sick, have either better opinion of Chemical Medicines then of others, or are pleased with their small, and commonly more pleasant dose. But that those parts into which Chemists reduce things, ●ee this largely disputed by Libavias' in exam. censur. Parisiens. are latent in the compound body, otherwise then by the Aristotelean distinction of formaliter and materialiter (so much laughed at by Mr. Glanvill, pag. 119.)

Having denied Mr. Glanvill, that by those useful and luciferous processes, Nature is unwound and resolved into the minute Rudiments of its composition. Which Rudiments were not made use of at the first Creation, when one Fiat created those compound bodies, which Artful Fires sometimes (and but sometimes) analyse into several parts, as Salts, Oil, or Sulphur and Spirit, and those grosser Elements of Earth and water. All which are not found in many bodies, (and when they are, it is with a great discrepancy betwixt those of one Concrete, and those of another) nor any of them to be De serment. c 1. p. 4. separated from Gold. Which Libavius, no, nor Dr. Willis doth not make to be the last unmixed, and simple Constituents of natural bodies, sed ejusmodi tantum substantias, in quas veluti partes ultimo sensibiles res Physicae resolvuntur: Substances into which natural bodies are resolved finally as far as sense can judge, and when the Analysis is prosecuted in one sort of procedure: for another method, different Solvents, and different Fires discover different parts, and those sensible too from what the usual Chemistry builds upon. Having denied him this, I must further tell him, that when the Countreywoman sets her Eggs to be hatched, she produceth by those means such bodies as no Chemical fires with their vexatious Analysis ever would discover: so she doth when she doth brew and churms her butter. Nor is this more evident, than it is clear that the Chemical principles, when they come to be accommodated to the solving of the Phaenomena in nature, or in diseases, have as much of darkness and dissatisfaction in them, as occurs in the Peripatetic way: so that now we are more dubious, not more knowing, then before: and this any man that hath considered how the Chemical Physicians disagree about the causes of diseases, and even about the common Phaenomena of Nature, will easily grant me: nor will it appear less manifest, that if the Chemical hypotheses do take place, that it will subject the Mechanic Philosophy, and establish that of Anaximander, revived by the ingenious Berigardus. But Mr. Glanvill adds, That Chemistry directs Medicines Plus ultra, p. 11. less loathsome, and far more vigorous, and freeth the spirits and purer parts from the clogging and noxious appendices of grosser matter, which not only hinder and disable the operation, but leave hurtful dregs in the body behind them.— This Plea for the preferring CHEMICAL Medicines before those commonly called Galenical, is much insisted on by Beguinus, Quercetanus, and others of that way. Yet, first it is observable, that whether we regard taste or smell, those very Authors recommend as odious medicaments, and as loathsome, as ever Coerdus or Foesius in their Dispensatories, if not worse. Will any man in his Wits condemn Wormwood and Centory because of their bitter taste, or Castoreum for the smell? Secondly, every thing is not the better for being extracted. ●reictag. nect. med. c. 75. p. 325. See Mr. boil of the usefulness of Philos. part 2 p. 148, etc. Thus the Extract of Rhubarb, though quickened with its Salt, is not so efficacious as plain Rhubarb, except it be sophisticated with Diagridium. Nor is Cynnamom improved by Extraction. Their being more vigorous and freed from grosser parts is not always a commendation, and sometimes it carries danger with it. That those grosser parts, and those natural vehicles are requisite, seems even thence clear, that their spirits & essences must be tempered and mixed often with other gross bodies before they be given. Those appendices of grosser See this point fully debated in the Vulgar Errors of Primrose, l. 4. c 3. which I desire Mr. Glanvill to read. In Pharmacop▪ August.

How many ways are there of preparing Hartshorn, yet is there not one that equals the crude Horn. I shall set down Zwelfers words, whose credit no Chemist almost will extenuate. Licet ex cornibus vel ossibus ita Philosophice calcinatis distillationi subjectis de spiritu sale volatili, & oleo ipsorum foetido nonnihil eliciatur, non tamen propterea existimandum ipsa adhuc iisdem quibus crudum cornu pollere viribus vel majoribus etiam (prout nonnulli sibi imaginantur & asserunt) vel etiam, ut alii arbitrantur, hac calcinatione nihil aliud peractum fuisse quam quod friabilia, ad pulverandum aptiora, & magis pura reddita sunt: Neutiquam, Quip, qui ambo cornua, tam crudum quam Philosophice calcinatum, examini ignis subjiciet, reipsa deprehendet multum de nativa sua humiditate, de sale volatili & oleo huic cornis Philosophice calcinato detractum esse, & eorundem vix parte quarta adhuc gaudere, ut propterea & hanc calcinationem Philosophicam, licet totali exustione aliquanto meliorem, approbare In prosecution of this point let any man consider, that Chemical oil of Anniseeds is not so effectual as the powder.

Nor is this more true in Hartshorn than in Vipers, which are more effectual being eaten as Eels, or by a common infusion in wine, or given in powder (plain powder) than when reduced to volatile Salt and Essences. It is also false, that Chemical preparation always amends, or doth not render some things worse: The ingredients of sublimated Mercury are not poison; the result is.

Nos tale vinum ad ventris lumbricos plurimum valere certo scimus. As for the hurtful dregs which the Galenical Medicaments are said to leave behind: I am confident, that whosoever shall inquire into the ill consequences of the two Pharmaceutics, will say, that if the Galenical be not always the most efficacious, it is always the most safe and innocent: and any man will be more apt to dread the violent impressions which the powerful spirits and minerals may make upon the membranes of the Stomach (which may introduce an irrelievable distemper in the torenus of that part, whereupon depends the nutriment, health, and vigour of the whole body) than any noxious faeces or little and remediable hurt from the generality of the Galenical Medicaments.

Gentlewomen oftentimes, as any ever were wrought by Chemistry. The Physic which is celebrated in the Scripture, that which St. Luke, St. James, Cosmas and Damianus, Joannes Damascenus, and others followed, was that which our Divine scruples, at least it leaves dregs in the body. I confess that among the Egyptians, and Arabians, and Paracelsians, and some other Moderns, Chemistry was very fantastic, unintelligible and delusive; and the boasts, vanity, and canting of those Spagyrists brought a scandal upon the Art, and exposed it to suspicion and contempt: but what the Society have done in order to its improvement, I understand not so well as Mr. Glanvill seems to do: the Treatise of Dr. Willis about Fermentation was writ before he was of that number: and I know not how he hath improved Chemistry much since. And in that famed Piece, all is not to be reckoned upon as invented (much His notion of Fermentation, as thereby he expresseth the natural and preternatural occurrences in our bodies, is taken from Bellich. defermentat sect. 89.

I shall add, that we owe not only the invention, and rude improvement of Chemistry to the Disputative followers of Hypocrates, Aristotle, Galen, those superstitious Porers upon the Writings of the Ancients, those ridiculous Schoolmen, and Monks, and Physicians, but even the present credit and esteem which it hath in the world, and upon which it hath so far advanced itself. It was not Paracelsus with all his noise and Insolence, but the Dogmatical Physicians, who observing the benefit thereof in Pharmacy gave it fame, and introduced it into the Shops, and Cabinets of Princes, and the use of serious and considerate Persons.

Minadous, Matthiolus, Libavius, and many other Physicians of the Hippocratical way introduced the sober and honest practice of it, and rendered it helpful to common life, perhaps our Virtuosos had never meddled with it, at least not have been able to give it any esteem in the world. But now that the Galenists and Aristoteleans, (as they are commonly called) have refined it from its dross, and cast off the Chrysopoietick and delusory designs, and magical intermixtures, and Rosicrucian vapours and superstitions, all which they effected; and gave Mr. Glanvill the opportunity of this Cant, with which I conclude this discourse. I confess, Sir, that among the Egyptians, and Arabians, Mr. Glanvill, p. 12. and Paracelsians, and some other Moderns, Chemistry was very fantastic, and unintelligible, and delusive: and the boasts, vanity, and canting of those Spagyrists brought a Scandal upon the Art, and exposed it to suspicion and contempt. Perhaps not so delusory as Mr. Glanvill thinks: but I am sure the projects some go upon are delusory, have much of the Rosicrusan humour in them: and ●he design of introducing a sensible Philosophy is the pretence of Crollius, and of the Rosi●rusive Order. But it's late Cultivators, and particularly the ROYAL SOCIETY have refined it from its dross, and made it honest, sober, and intelligible, an excellent Interpreter to Philosophy, and help to common life. For they have laid aside the Chrysopoietick, and delusory designs, and vain transmutations, and Rosicrucian vapours, Magical Charms and superstitious suggestions, and form it into an instrument to know the Depths and Efficacies of Nature.— All this without dispute the Society hath done; and without disputing. And hereupon I do agree with our Virtuoso, that they have no small advantage above the old Philosophers of the Notional way. Of Anatomical Improvements. WE have another advantage above the Ancients in the study, use, and vast Improvements of Anatomy, Plus ultr●▪ p. 12. which we find as needful to be known among us, as 'tis wonderful 'twas known so little among the Ancients, whom a fond Superstition deterred from dissections. For the Anatomising the bodies of men was counted barbarous and inhuman in elder Times: And I observe from a learned man of our own, that the Romans held it unlawful to look on the Entrails. And Tertullian severely censures an inquisitive Physician of his time for this practice, saying, That he hated man, that he might know him. Yea, one of the Popes (I take it 'twas Boniface 8.) threatens to excommunicate those that should do any thing of this then-abominable nature. And Democritus was fain to excuse his dissection of Beasts, even to the great Hypocrates. Nor does it appear by any thing extant in the writings of Galen, that that other Father of Physicians ever made any Anatomy of humane bodies. Thus shy and unacquainted was Antiquity with this excellent Art, which is one of the most useful in humane life, and tends mightily to the eviscerating of Nature, and disclosure of the Springs of its Motion. I have set down without any interruption the words of this English Bravo and Hector of our Modern Philosophers, that my Reader might come with a greater expectation to the perusal of my Animadversions: so high a charge of ignorance upon the Ancients, such useful discoveries of the Moderns render the former to be contemptible fellows▪ and the latter a very beneficial and important p●r●y in this Age. But if it do appear that the Moderns have not as yet convinced us by their works and great performances in Physic, that the knowledge of these new inventions is so necessary to Physicians, and so advantageous to mankind, but that those which either slight or ignore their discoveries, acquire a greater repute, are more employed and possessed of a more honourable and gainful practice, and, in fine, do greater Cures in general, than our Braggadochios; then is there no such reason for this Triumph of Mr. Glanvill, as he imagines. The better to judge hereof, I desire all considering men to look back upon the several Physicians, who have flourished in Greece, Rome and Barbary, and to view the present state of Physic in Italy, Spain, and France, and try his most severe judgement if it be possible for him to condemn that Physic as imperfect and pitifully deficient, which gave that credit to Hypocrates, Galen, Rhases, Avicenne, Fernelius, Lacuna, Mercatus, Vallesius, Christophorus, and Thomas a Veiga, Claudinus, Massarius, Septalius, Rondeletius, Hollerius, Ballonius, Rodericus a Castro, Fonseca, Saxonia, Sennertus, Crato, Prosper Alpinus, Antonius Musa Basavola, Hoffman, and many others whom I shall not name; as indeed I name these without any order) which they now enjoy. Let him set his most ambitious thoughts on work, and see if he can propose to his desires greater things than they attained unto, and achieved. Let him employ all his envy, and yet condemn their Diagnosticks, Prognostics, or that Secretorum Secretissimum, their method of curing, and their Medicines. If there be little or no fault in these parts, it signifies not much what principles they went upon in Philosophy, nor whether they did mistake or ignòre some things in Anatomy, as long as they were not such as hindered a Physician from the obtaining of that end which is designed by his Art: And as to the improvement of the Therapeutic part of Physic, by new Medicaments, or new and more pleasant preparations of old Medicaments, if they be no more efficacious than the former, we pay to the Inventors those acknowledgements, which we do to the introducers of new garbs and fashions of clothes, the best contrivances whereof, howsoever they may excel in conveniency, cannot be endeared unto us by the representations of being necessary. I have named practical Physicians; I shall now instance in Chirurgery: What man is there in this Age, that would not be content with the repute of Ingrassias, Vesalius, Fallopius, Carcanus, Aquapendens, Spigelius, Marchettis, Severinus Paraeus, Chalmetaeus, Pigraeus, Guillemeau, Hildanus, & c? or what man is there in this inquisitive Age, that any sober man would compare with them, much less prefer before them? If the Posture of Physic be such, and that the value we ought to place on every thing be to be regulated by its subserviency and conduciveness to some end, (finis conciliat mediis gratiam) it is easy to judge what certain esteem we are to put upon the modern Improvements of Knowledge in order to Physic, and how far we may justly censure the Ancients, and such as either slight or are ignorant of them. I profess myself not to know what disease it is that the Virtuosos cure better, or with more certainty than those that follow those other of the Dogmatical way. If it were done, there would not want such as should cry such performances up; besides the interest of the novelists, the sense of their great Cures, would gain them all the practice that is now in the hands of such as vary not from the ancient Method, and Rules of that Art. I shall add, that I could demonstrate by undeniable testimonies, and such as are confirmed by modern trials, that the introducing of new Medicines, either Chemical, or otherwise, and the neglect of a diffused reading, hath occasioned the dis-use and ignorance of several Medicines for Consumptions, the Gout, Plague, and other grievous diseases, which might be attempted with much more assurance, then is to be placed upon the later Methods. To prosecute this point further, I shall tell you, that Physicians hitherto looked with a great indifference upon the Principles of natural Philosophy, whether they were true, or no; so that they did but serve as convenient Memorials to regulate them in their practice, and that they did guide them to their wished end with such certainty, as if they were true. All disputes about Natural Philosophy that did not refer to practice, they looked upon as Curiosities, going beyond their Art, and about which they would not contend, so as that the Method of curing were not undermined thereby. Upon this account they did allow of two sorts of Truth, the one in Physic, the other in Natural Philosophy, and that what was such in one, might not be such in the other. This Precedent they derived from their great Master, Hypocrates, who in his discourses sometimes proceeds upon the Doctrine of the four Elements, as if that were true: Sometimes he goes upon the doctrine of Atoms, as if he regulated his Cures thereby: sometimes he seems to favour the Tenets of the Chemists; See Otto Tachenius's Hypocrates redivivus▪ and his Clavis Medic. Hippocr. Devet. medic § 24 Concerning the meaning of which place see Erastus adv. P●rac. p. 3. pag. ●6 & Con●ing. de Hermit. med. c. 16 p▪ 191. and he cries out as Mr. boil, and other Chemists cite him, Non calidum, frigidum, humidum, siccum esse quod maximam vim agendi habet in corpore, verum amarum, & falsum, & dulce, & acidum, etc. Sometimes he proceeds as it were upon the principles of the old Methodists, and ascribes the origin of diseases to the altering of the texture of the body, to the different conformation of parts, the different configuration of pores, etc. This was the course that Great Man took: he was willing to observe in all diseases the motions and the course Nature took; to take those for ill signs and symptoms, which he found to be such from that great Instructor; however 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉, those ways whereby Nature did usually terminate diseases, were the ways he thought they ought to be terminated by; and he made that the scope to be aimed at in the curing of diseases: those evacuations that had helped naturally to cure, he endeavoured to promote artificially, by such Medicines as Experience showed to be serviceable to those ends, when administered at due times and seasons. In short, he made himself absolutely the slave of Nature, attended on her motions, sometimes gently leading her on, as it were a Gentleman-Usher; sometimes following her, as a Page, never pretending to command her by his Medicines: So cautious he was, that he would not adventure to do good unseasonably, and at other hours than his Teacher directed him, lest he should do harm: he would not adventure to shorten a disease, lest he should shorten his Patient's life. As if he had foreseen the truth of that observation▪ which Vallesius, and others in these days experiment, Celerior quam pro morbi longitudine curatio, detrahens plus virium quam Consultius esse nullus nescit tempore paulo longiore & tuto curari, quam paulo breviore cum certo vitae periculo sanari. Erastus disput. de propriet. med. c. 65. sub finem. pro morbi ratione, facit in tempore curandos ante tempus mori. Agreeable to this Method of Hypocrates, was that counsel which Dr. Bathurst (of Blackfriars) gave me, when I first seriously set myself to study and observe his practice in Physic, viz. Nunquam ille Medicus magnus erit, quisquis patitur sese principiis Philosophicis alligari atque constringi. It is impossible for any person to be a great Physician, who ties up himself to one sort of Natural Philosophy, as if it were really true and certain: the operation of Medicaments is oftentimes such as answers not the Principles of any Philosophy, and the digestions of Nature are so different from those of Chemistry, her fires, her solvents, her filters, her furnaces & vessels, her mixtures and degrees of heat so discrepant, that there is no arguing from the one to the other: nor is there any thing to be relied upon in Physic, but an exact knowledge of medicinal Phisiology (founded upon observation, not principles) semeiotics, method of curing, and tried, (not excogitated, not commanding) medicines: where this course fails (as sometimes it will) we then try uncertain Medicines, rather than abandon the Patient to those Prognostics, which are seldom so fatal as to destroy all hope; and where Skill is at a loss, we frequently behold Chance to be successful. And this last is the Mystress of our Reforming Physicians, it is under her conduct that they will enrich our Therapeutic part of Medicine, and alter our Method. I shall not enlarge further hereupon, being content to have showed what esteem Physicians have had Philosophy in, and how they have had as little regard to the truth of their principles in natural Philosophy, as a man ought to have to the hand of a Dial, or which points out the way to any place: It is not requisite that it be a real hand, whatever men call it; nor would we endure the impertinencies of any that should go about to persuade us out of our way, because they that called that an hand, were mistaken: In sum, so the way be good and certain, I am content to be one of those whom the Italian Proverb commends, for going that way which the Mules go. Ito qua Muli eunt. In this opinion I have amongst late Writers the learned Hoffman, whose words are these. Quae enim necessitas est Instit▪ med l. 2 c. 〈…〉. 11▪ 1▪ etc. & 〈…〉.

Nor will it be amiss to propose the Judgement of the learned Practitioner Joannes Antonides Ʋander Linden, which he Jo. Ant. Ʋander Linden de circuitu sanguine. exercit. 1. sub finem. passed not long before his death at Leiden A. D. 1659. after a mature consideration of all the new speculations in Natural Philosophy, which this last Age had produced and acquainted him with.

Upon this account I often laugh at our modern Virtuosos, when they dilate themselves with a great deal of ostentation and confidence, about the qualities and correctives of Opium, whether it be hot or cold? which controversy how great soever, hath no influence upon practice, because both agree pretty well in the cases in which it is to be used, and man● of the modern preparations and corrections are foolish, and make it worse; And as to that Laudanum of helmont's amongst the Virtuosos; I have seen much more simple preparations stupefy less, and produce greater Cures, then that did when made by the hands of one of the Society, and given by another of it: whilst the best of Modern Chemists, Pharmacop. August incons. Archigenis. Zwelfer; bestows this commendation upon that old medicine of Archigenes and Mesues— Erit sic rite praeparata opiata, quae merito Laudani opiati, multarumque aliarum Opiatarum vices supplere posset. I could enlarge here, but that Mr. Glanvill will think I have forgot him. Having made this general Apology for Physicians, which is sufficient to justify them, both as to their care of their Patients, and their skill; I shall come to apply my discourse particularly to Mr. Glanvill. It is hard to reconcile the necessity of Anatomy, with the Mosaical Constitutions, it seeming strange that God should make it so unclean a thing for any one to touch a dead body, and yet the knowledge of Sceletons should be so necessary. To supply this, the Jewish Rabbins say, that God Almighty did reveal unto Moses the accurate knowledge of Anatomy: and when we consider how they embalmed their dead, and that embalming doth infer a knowledge of dissection, and of the Entrails; when we observe (out of buxtorf's Synagoga) that artifice with which the Jews kill all Animals, thereby to let out the blood exactly: when we consider that the multiplicity of accidents in war, or otherwise, would render the knowledge of the inward and outward parts necessary to them, and experience acquaint them with their nature (not to mention some Jewish relations about the Vid. Riolan. Anthropog●. ph. l. 1. c. 3. opening of the Os pubis and the partus Caesareus) I am apt to think that the ancient Jews were not ignorant of useful Anatomy, nor so superstitious as totally to avoid the practice of it; nor dare I say (with our Virtuoso) such Superstition is fond, which is ascribed to God as its immediate Author. As for the Greeks, the study of Anatomy was very ancient amongst them, since it is attributed to Alcmaeon▪ that ancient Physician (a Scholar of Pythagoras) as the first Author of it, if we will believe Chalcidius upon the Timaeus of Plato. From him it was derived to posterity by tradition and manual operation, children being bred up unto it, such as were to be Physicians, as also Philosophers. So Democritus, Hypocrates, and many others came to be acquainted with it. But none of the Ancients, until the time of Diocles Garystius, did Hieron. Mercurialis Var. Lect. l. 1. c. 10▪ write any thing about it: which notwithstanding, that Science seems to have been in never These Anatomical operations of the Youth were called 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉, which Hoffman thinks may be rendered fitly in▪ a●n●, Exercitia Anatomica.

Lect. l. 2. c. 13. The same is avowed by Vesalius in his Preface to Charles V. the worse condition, as Mercurialis thinks. Anatomen etsi a nullo veterum usque ad Dioclis aetatem Scriptis mandatam referat Galen. in 2. de anat. admin. melius tamen sic conservatam & amplificatam inde intelligere possumus, quod tunc homines a primis annis Anatomen (ut caeteras arts,) non ex scriptis sed ex Parentum sermonibus ipsaque exercitatione addiscebant; sicque melius ipsam comparantes, non modo tenacius in animis servabant, verum etiam assiduis studiis augebant. But to put this question more out of doubt, I shall appeal to Galen, who could give a better account of what they did in the elder times then Mr. Glanvill. I have not his Works by me; but Lacuna in his Epitome thus expresseth him." Quod veteres nihil scripserint de Lacunae Epit. Galeni de anatom. admin. l. 2. consectionibus administrandis, vertendum illis vitio non est: quandoquidem erat iis tum frequens tamque in communi usu ipsa Anatome, ut domi apud Parentes etiam ab ipsa pueritia, in illa omnes olim exercerentur. Postea vero tam praeclaro illo exercitio intermisso, opus certe nobis fuit Commentariis, quae Anatomicam disciplinam Chirurgicae medendi rationi maxime necessariam, integram conservarent. That Aristotle did dissect the bodies of men is manifest out of his Hist. Anim. l. 3. where he informs us how he made an inquiry into the nature and series Vide Riolan. Anthr. p●g●aph. l. 1. ●4. of the veins in humane bodies: and as to his anatomising of other creatures, beasts, birds, I would not be understood to justify every passage in Aristotle relating to Anatomy: he hath many gross errors opere in longo: but have not also Harvey, Highmore, Silvius, and others, so many as may excuse his incogitancy sometimes? fishes, infects, (and how he had some thousands employed under him to that purpose) no man can doubt who reads Riolanus and Pliny l. 8. c. 18. How accurate he was (however his brevity doth not represent every circumstance, nor fully describe things) we may judge by this that there are few of the new inventions, but are ascribed unto him; and Dr. Harvey is known D●▪ Pearsoni ● Dedic. Laertii ad Carol. II. commonly to have said, Nihil fere unquam in ipsis Naturae penetralibus invenisse se▪ quin cum Aristotelem suum pensiculatius evolveret idem ab illo, aut explicatum, aut saltem cognitum reperiret. After Diocles, I find these other reckoned as notable Anatomists by Volcherus, Coiter, viz. Polybius, Erasistratus, Callistus, all Scholars of. Aristotle: And after them Marinus, and Lycus, Vol. Coiter intro. inanat. c. 6 Galen in his Comment upon Hypocrates de nat. hum. reckons up above ●0 eminent Anatomists of the ancients. Vide Riolan. Anthropogr. the Master of Galen, and Satyrus, and Pelops, and Numesianus, besides several others at Alexandria all which Galen went to converse with. But I must not pass by Herophilus without an especial Character, who did not only correct the mistakes in Anatomy which his Master Praxagoras fell into, but by his industry and skill acquired a repute so great, that his name is equal to the most famous that ever were before, or since his time: This great man is preferred by Vesalius before Galen: And it was an usual saying of Fallopius, that any man might as easily contradict the Gospel, as contradict Moebius fundam. med. c. 1. p. 10. & V●ssius de philos. c. ●1. sect. 2. Herophilus in Anatomy. Contradicere Herophilo in Anatomicis est contradicere Evangelio. This man is that inquisitive Physician, of whom Mr. Glanvill speaks, and who is blamed by Tertullian not for dissecting humane bodies, but for dissecting them alive, which he terms Butchery. Because, I think Mr. Glanvill never read him, and because I will make it evident that one of the Ancients did dissect more bodies of men, than all the Society put together, and that with an extraordinary caution. I shall set down the words of Tertullian, and Tert●llian. de anima. c. 10. Gagr●us, Mercurialis, & Vossius read it see, ringentoes exsecuit. they are these,—— Herophilus ille Medicus aut Lanius, qui sexcentos eexecuit ut naturam scrutaretur, qui hominem odiit ut nosset, nescio an omnia ejus interna liquido explorarit; ipsa morte mutante q quaevixerant, & morte non simplici, sed ipsa inter artificia exectionis errante. Upon which passage, Philip le prieur notes thus, Anatomia quae & celebris magnoque in precio fuit apud Ethnicos, a veteribus Christianis odio quam maximo afficiebatur. Quamvis hic dictum Lanium Herophilum constet, quod vivos homines dissecaret▪ Id autem facere solitos Erasistratum, Dioclem, & Herophilum docet Claudius Galennus 8. de plac. & 2. anatom. administr. Agreeable to of Tertullian, is that passage of Cornelius Celsus in his Preface. Celsus l. 1. in prooemio. Necessarium ergo esse incidere corpora mortuorum, eorumque viscera atque intestina scrutari, longeque optime fecisse Herophilam & Erasistratum, qui nocentes homines a regibus ex carcere acceptos, vivos inciderint, considerarintque etiam Spiritu remanente, ea quae Natura clausisset, eorumque posituram, colorem, figuram, magnitudinem, ordinem, duriciem, molliciem, laevorem▪ contactum: processus deinde singulorum & recessus, & sive quia inseritur alteri, sive quid partem alterius in se recipit. This Herophilus was undoubtedly a person of vast parts, great learning and curiosity. He brought the Hippocratical Physic to its height and perfection, completing the Anatomical part, and illustrating the Doctrine of the Pulses. His followers had a School not far from Laodicea, as Strabo saith, wherein it is not to be doubted but that Anatomy was taught, and so in that other School of Erasistratus at Smyrna. 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 Strabo Geograph. in fine lib 12. citante Mercuriali Var. Lect. l. 2. c. 12. From whence it is clear, that in the Reign of Augustus Caesar (when Strabo lived) Anatomy in the East was in great request, and that the Physicians and followers of Herophilus had a great Academy betwixt Laodicea and Garura. And that before those times at Smyrna, Erasistratus that was a great Dissector of men (even alive) had another Academy of his followers: whose works Vesalius de rad. Chinae, p. 163. though they are lost, yet Vesalius saith, that one may conjecture out of the passages in Galen that relate to them, that they were very accurate Anatomists.— Veteribus dissectionum proceribus, quos ex Galeni libris in corporum anatome sedulo versatus esse nobis persuasum est.— Not much unlike this character of Vesalius is that Elegy which Veslingius bestows upon the Ancients in an Epistle of his to C. Hoffman, enquiring whether the venae lacteae of Asellius were a part of the portavena known so long ago? Sic habeas, incertum mihi esse quid primi illi qui ante Dioclis Carystii aevum privatis a●ffectionibus in corporis humani partes inquirebant hic viderint, cum nihil eorum quae cognorant scriptis divulgarint. Vixere fortes ante Agamemnona multi, ait Lyricus: & proculdubio ante Herophilum eximii, & in hoc dissectionum studio exercitatissimi, quos ob monumentorum defectum longa nocte oblivio premit. Veslingius Ep. 20. edit. per Bartholin. I shall conclude this discourse of Herophilus, with an observation about the time when he lived; which was not in the days of Tertullian, though Mr. Glanvill represents them as Contemporaries: but many Centuries before, in the time of Ptolemaeus Philadelphus, and he is famed for his raillery upon Diodorus Cronus, who denied there was any motion, yet had his shoulder dislocated. See Conring. de medic. Hermit. c. 9 p. 83. Some make him more ancient, but none ever brought him so low as our Virtuoso. Vide Voss. de Philos. c. 11. Jonsium de Script. Philos. l. 1. c. 15. As to the Romans, and their skill in Anatomy, I cannot say much of it, except it be to their disparagement. They were a military sort of people, rough-hewen, and thought all that below their studies or serious thoughts, which our Experimental Philosophers boast of, and recommend unto our care with so much vanity. All the Mechanic, I had almost said the Liberal Sciences, they thought to be excellent qualifications in their slaves, not in themselves: And they who gave Laws to all the world, scorned to be instructed by their vassals, and a conquered Nation. Upon this account, not only in the time of Tully, but afterwards to the days of Quintilian and Tacitus, (I know not which writ the Book De Oratoribus) it is evident, that however many Gentlemen did inform themselves of the several parts of ingenious Learning, yet did that haughty people behold those persons with indignation, and some thoughts of hatred, in so much as that those who were best versed in it, pretended ignorance and scorn of it. Things being in this condition, and the Romans having no other Physicians than their Slaves, it is not to be wondered if they were not eminent for Anatomy. Cato had banished the Physicians long ago, and after-ages gave them little encouragement. I do not at present remember any Physician, whose name hath any thing of the Roman till Cornelius Celsus, and after him Vectius Valens. Pliny saith, that even to his time, in the reign of Titus Vespasian, the Romans did not care to profess and practise Physic. Solam hanc artium Graecorum nondum exercet Romana gravitas in tanto fructu: paucissimi Quiritum attigere, & ipsi statim ad Graecos transfugae: imo vero autoritas aliter quam Graece eam tractantibus, etiam apud imperitos expertesque linguae, non est.

There Herophilus and his Scholars had given it credit, and the Empirics and Methodists had their Academies. and the Jacrosophistaes' were endowed professors The repute of Alexandria being such▪ even in the da●s of Valentinian, that it was credit enough for any Physician to say he had been b●ed these.

Pliny calls Themison, Summum authorem, 〈◊〉 14. c. 17. and by that place in Juvenal one would guests him to have been a man of great notice and general practice in the days he lived. Morborum omne genus, quorum si nomine quaeras, Promptius expediam quot amaverit Hippia moechos, Quot Themison aegros autumno occiderit uno. Thessalus, against whom Galen and Pliny inveigh was certainly a man▪ not only of great Eloquence, but also of extraordinary Learning and Judgement, as we may guests by those parcels and fragments of that excellent man, which are all that remains of him, and they preserved in the works of others. His Books de Communitatibus & Syncriticis are pieces whose losses I much lament. The Memory of his Tomb is not lost upon which he inscribed himself, 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉, or, The Conqueror of Physicians. His Letter to Nero had something of a gallant confidence in it, which may become Heroes, and is justified in men of great Learning.

The generality of his followers seem to have been excellent Physicians, as Dionysius, Proculus, Archigenes, Soranus, Attalus, Julianus, and others. I shall not insist upon a particular relation of their tenets, Prosp Alpin. de medic. methodica. which one may see excellently illustrated by Prosper Alpinus. This sect of Physicians seems to have left impressions Quintilian being to describe Physic, renders an a● count of it agreeable to the Methodists. In declam. 8.

They placed little They called Galen▪ when he put himself ●orth in the world by the ostentation of Anatomy and Philosophy, Logiater: Logiatri autem nomen sui tempori: medici Romae Galeno per contemptum imponchant; ut ita eum traducerent, quasi non reipsa, nec usu▪ & ●xercitio artis peritus esset: Sed ad loquacit▪ tem d●ntaxat & disserendum de iis quae ad a●tem pertinent comparatus. Gesner. in Schol●is ad Cassium P. 57 value upon the exact knowledge of Anatomy, being content with a general skill therein, and enquiring no further than was necessary. They knew that the Romans had formerly banished the Physicians (as Archagathus) from amongst them, for using their Patients with much cruelty, cutting and burning them; and understood the humour of the people so well, how they disliked the dissections of humane bodies, especially alive, and therefore they closed with that popular prejudice, and turned it to their advantage; neither dissecting of bodies, nor tormenting them with those odious or cruel methods of Cure, which were practised by the followers of Herophilus. Nor do I doubt that those objections in Celsus against Anatomy, were put into his mouth by the Methodists, as well as Empirics, viz. that all Anatomy of bodies was a nasty performance; but to dissect the living, most barbarous and cruel: that as much of Anatomy as would instruct one sufficiently, might be learned in a Camp, where the Physician need not make wounds, but learn at once and practice Cures. Hence it was that the study of Anatomy was so much out of request at Rome in Galens time, that I think he mentions not one curious Anatomist there, though he tell how Satyrus taught him at Pergamus, and Pelops at Smyrna, and Numesianus at Corinth, and others. There were some that were excellent Ostrologists at Alexandria. And I am apt to think, that even he durst not for fear of public odium, dissect any living men there, because, as Celsus saith, most people held it to be cruelty, and perhaps would not have thought well of him, who should have dissected any dead men. Whereupon he set up with Apes, dissecting them, as being nearest to men in resemblance, Vesalius in his Treatise decad. Chinae showeth bow Ga' en dissected Apes, and was thereby led into sun dry mistakes But even such as did blame Galen were themselves faulty, as Vesalius and Columbus; which appears by what they say about the kidneys; which they describe out of brutes, not men, as Piccolomineus and Beverovicus observe ●everovic. de calculo, p 3 Read also Fallopius Observations and imagining the fabric of their bodies to have as great an affinity with the parts of men, as their shapes had; that this was the cause of many mistakes in him, is certain; and demonstrated by Vesalius. But that he never made any Anatomies of humane bodies, or considered any as they came in his way, is a calumny which might be refuted by sundry instances Vesalius in ded ●c. lib. de sabric. corp. hum. ad Carol V. Imper. In the same place ●e calls Galen, dissectionis professorum facile primariam. out of his Works, and some thereof are to be seen in Riolanus Anthopogr. l. ●. c. 12. Vesalius never raised his imputations to this height; all that he saith of this nature, is, Nobis modo ex renata dissectionis arte, diligentique Galeni librorum praelectione, & in plerisque locis eorundem non poenitenda restitutione constat, nunquam ipsum nuper mortuum corpus humanum resecuisse. At vero suis deceptum Simiis (licet ipsi arida, ac veluti ad ossium inspectionem parata hominum cadavera occurrerint) crebro veteres Medicos, qui hominum consectionibus se exercu●rant, Galen. l. 3. sec, gen. c. 2. immerito arguere. Nay, it is evident out of Galen, that the Roman Physicians which were in the Army of Antoninus did dissect the Germans that were killed by him in battle. As for that Learned man of our own, out of whom he tells us, That the Romans held it unlawful to look on the Entrails: I know not who it should be. Mr. Boil indeed doth say, that in Galens time it was thought little less than irreligious, if not barbarous, to mangle the bodies of men: which how far it is true, one may guests out of what I have said; But that Honourable Person speaks in such a manner as gives us little of exception; Mr. Glanvill is so peremptory, that I wonder that he did not deny, that the Romans did not use any Augury from the inspection of the bowels, heart, and liver of beasts; or that they did not eat the Livers of Geese, and other Guts of several Animals. This is so well known to every School boy that hath read Martial, or Horace, or Virgil, that I need not speak of it. Had the Romans held it so unlawful a thing to behold the Entrails of Animals, I wonder they gave the name of Visceratio to those distributions of flesh which they publicly used: to such unlawful customs, Virgil would not have alluded, when he brings in Dido herself, — Pecudumque reclusis▪ Pectoribus i●hians spirantia consulit exta. Aeneid. l. 4. v. 64. & Georgic. l. 1. v. 484. Tristibus aut Extis fibrae apparere minaces. Nay, they carried the bodies of beasts open with their Entrails displayed to be sold publicly, as Mart. shows l. 6. ep. 64. N● valeam, si non multo sapit altius istud, Quod cum panticibus laxis, & cum pede grandi Et rubro palmone vetus, nasisque timendum, Omnia crudelis Lanius, per compita portar. But perhaps he will confine his discourse to the Entrails of men, why then did not he speak more plainly? And even in this case, that some superstitious persons might hold it impious and unlawful is possible▪ and that others out of enmity to the Anatomical Physicians, (as Pliny l. 28. c. 1.) Aspici humana exta nefas habetur, might▪ 〈…〉 that pla●e in Pliny relates only ●o Argufy, that i● was not lawful amongst m●n t● make use of humane bodies, and search their bowels to th●se ends: this was nefas: but nothing else. call it so, I deny not. But what Law was there against it? How comes it to pass, that Celsus in his debate about the lawfulness of Anatomising even living bodies, saith (or maketh others to say) that it is only cruel, or nasty and abominable; not impiety or a breach of Religion? Besides, how could any Physician in those days have dressed such wounds in which their Entrails either gushed out, or were hurt, in case it had been unlawful to look upon them? It is manifest that Celsus saith, a prudent Physician may from such accidents learn Anatomy; Ita sedem, positum, ordinem, & figuram, similiaque alia cognoscere prudentem medicum, and adviseth him to improve the occasion: And he was a Person learned not only in the Physic, but Civil Laws of his Country. To convince our Virtuoso a little more, out of School-books, in which he ought to be conversant. Is there not a controversy agitated in Seneca, Controvers. l. x. contr. 6. about Parrhasius the Painter? how he brought an old Olynthian, and dissected him alive, thereby to draw the picture of Prometheus with a vulture preying upon his Liver! Is it not agitated pro and Con, by Romans and Grecians? Is there any one that saith it was unlawful for him to behold the Entrails? Nay, is it not said in the midst of Rome, that it was always LAWFUL? In argumentis dixit, quantum semper Artibus LICUISSET, Medicos ut vim ignoratam morbi cognoscerent, viscera rescidisse HODIE cadaverum artus rescindi, ut nervorum articulorumque positio cognoscipossit. In Quintilian is there not a Declamation Declam. 8. (Gemini languentes) in which the Mother accuseth the Father for permitting the Physician to dissect one of the sick twins, thereby to discover the disease of the other! Doth not the Mother there bid him dissect the bowels of the dead youth? Differ saltem, pater, hanc calamitatem: quicquid ex filio facis, facies ex cadavere. Si deprehendi potest languor dum occidit, facilius cum occiderit. Doth she not describe the cruelty of that Anatomy very tragically? Passus est miser discurrentem per omnia reserati pectoris improbum vagae artis errorem. Contentum fuisse medicum toto homine discurrentem primo putatis aspectu? Egesta saepe vitalia, pertractata, diducta sunt: fecerunt manus plura, quam ferrum. Stat juxta medicum pater apertis visceribus inhians, stillantem animae sedem cruentis manibus agitantem: ne festinet, hortatur; jubet altius diligentiusque scrutari: Interrogat, dubitat, contendit, affirmat, & accepit de filii morte rationem— Inter haec reficiebatur miser haustibus, detinebatur alloquiis, comprimebatur residuus cruor, claudebantur aperta vitalia. Nemo unquam tam nova pertulit commenta ●evitiae, tanquam sanaretur occisus est— Vos tunc putatis illius tantum languoris medicum quaesiisse causas? quaesivit quicquid nesciebat, & usus occasione rarissima in omnem voluit proficere novitatem. After this she tells in what manner she gathered up his bowels, and by closing up his Corpse fitted him for the Funeral. Corpus quod medicus, quod reliquerat pater, hoc sinu misera collegi, ac vacuum pectus frigidis abjectisque visceribus rursus implevi, sparsos artus amplexibus junxi, membra diducta composui. If any one can imagine, that this great Orator in so solemn a Declamation would have omitted so important an objection as the unlawfulness and impiety of beholding the entrails of the youth, certainly he thinks too meanly of the judgement of Quintilian, and too well of his own. It appears out of that Oration, that they had seldom opportunities of dissecting men alive, and therefore he calls it rarissimam occasionem. And that they were not ignorant of Anatomy and the inward fabric of humane bodies, it is evident further out of that Oration, where the Mother says the Physicians must needs already have learned that part of their Art. Sufficit quod aliquando jam facta How could they behold the Ludi Circenses, the Gladiators fight in the Theatre, and at the tombs of the deceased; or those s●d spectacles described by Martial? I profess I think it as gross a mistake to say they held it unlawful to behold the entrails▪ of men, a● to deny the Augury by beasls. ex unius hominis inspectione, ad totius intellectum naturae medicina pr●fecit. Quid allaturus huic aegroto es, quod non tot seculorum, tot languentium experimenta deprehenderint? As for what Mr. Glanvill saith about Democritus, that he was fain to excuse himself to Hypocrates for dissecting of beasts; this is as true as all the rest. Never was there a fitter second for Mr. Sprat, than Mr. Glanvill. They do not cite, but invent stories, and that with so much confidence, that a man must be assured by his own reading, before he can suspect theirs. That Hypocrates was a diligent Anatomist, is a thing every one must confess who either knows the manner of their education then, or hath looked into his Anatomical books de locis in homine, de fracturis, and sundry other pieces of his. That he not only contemplated the seat and action of parts in the dead, but living, appears by this passage, De Articulis sect 43▪ where he speaks about the setting of the Sphondyles of the back; Itaque si tale contingat, palam Pag. 800. ●om. 2. edit.

Atque ut extaret aliquod monumentum aeternum & immutabile suae diligentiae, laborisque in hoc fludio exantlati, sceletum aere fabricatum Apollini Delphico consecravit: ut Author est Pausanias lib. 10. And is it credible that ever Democritus should be forced to excuse himself to Hypocrates for cutting up of Animals, as if it were so uncouth and strange to him? I cannot answer for the Intellectuals of our Virtuoso, but no man of an higher capacity can believe it. The pleasantest part of this Narrative is, that there appears no such thing upon record. First of all the story of Democritus, how Hypocrates came and found him busy in dissecting of Animals, is called in question by Cortesius in Miscellaneis, as Riolanus tells me. And indeed I cannot persuade myself that those Letters in the end of Hypocrates works are genuine. But to pass by this exception. All that Hypocrates writes in his second Letter to Damagetus amounts to this. That at the request of the people of Abdera, he came to cure Democritus of his supposed madness, that being conducted to his house, he found him sitting under a Plantanus tree in a garb not much differing from a madman, and postures that had something of the same humour: Ipse Democritus sub ampla & humillima plantano sedebat, in veste crassa citra humeros desinente, solus, discalceatus, super lapidea sede, valde pallidus ac macilentus, promissa barba—— Ipse vero cum inculto ornatu, super genibus, librum habebat, sed & alii quidam ex utraque parte adjace●ant. Accumulata etiam erant Animalia multa per totum resecta. Et ipse quidem aliquando concitate incumbens scribebat, aliquando quiescebat, diu multumque se continens, & in seipso m●ditans. Deinde non long post, his peractis, exurgens deambulabat, & viscera animalium inspiciebat, & depositis ipsis digressus, rursus desidebat.— When Hypocrates approached near him, he was busy writing, and even then his deportment had something odd and Enthusiastical in it. 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 After the first compliments (which arr great 〈…〉 usual in those days) Hypocrates demand●● of him 〈…〉 ●e was writing? He replied about 〈…〉 about that, said the great Physician? To which he answers again thus. 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉. Quid enim, inquit, aliud quam quid sit, & quomodo in hominibus generetur, & quomodo allevetur. Nam animalia haec, quae vides, inquit, hujus gratia reseco, non quod odio habeam opera Dei, sed bilis naturam ac sedem quaerens. How much this and the whole passage of that Interview makes for Mr. glanvil's purpose, I see not. Hypocrates doth not blame him for anatomising of animals, nor is surprised at the novelty, nor troubled at the impiety of the action. Democritus knowing what apprehension the people had of him, and fearing lest the garb and posture he was in might confirm to Hypocrates, the truth of the report tells him how he employed his thoughts, and that the Animals that lay there upon the ground, were not slaughtered by him in a frantic rage, out of hatred to the creatures of God; but cut up Anatomically by him, thereby to discover the seat and nature of the gall, and the effects it had upon Maniacks. Whereupon Hypocrates was wonderfully pleased with the testimony he gave of the soundness of his judgement, and after some other prudential discourses, departed, satisfied about the good condition of his Patient. But if Democritus were not out of his Wits, I believe Mr. Glanvill was to allege such an impertinent story. But idle persons, that would upon easy terms acquire the repute of Learning, by citing quotations, are often thus imposed upon, and liable to mistakes. And perhaps there may be some person in the world that I know not of, who may have abused our Virtuoso in this case: but He should have minded the Text better. What Pope Boniface the Eighth did, I know not. But I am apt to suspect a person that hath told me so many untruths. The place in the Canon-Law, which I am apt to believe Mr. Glanvill never saw: It is lib. 3. Extravag. titulo de Anthropogr. l. 1. c. 12. sepultura. And Riolanus, whom I had rather credit, gives this account of it; Inter Christianos Papa Bonifacius octavus barbarum & inhumanum judicavit, peregre mortuorum corpora exenterare, carnibusque spoliare, ut ossa le●ta & tersa in locum sepulturae, quem vivi delegerant, commode perferri possent. It seems that Pope thought it an inhuman and barbarous thing not to dissect bodies for information sake; but to embowel them, and reduce them into Sceletons, and so to carry their bones to distant places to be buried according to the desire of the deceased. I am apt to think this Canon was never applied to Anatomy, and perhaps there is nothing of Excommunication in it, since Riolanus doth not mention it. As for the gross errors in Anatomy which Galen is charged with, I know not one that incommodates a man in point of Practice, but that the Method he took (however founded on false principles) was secure and good. Upon which it happened Hinc [Galeno] universi fidem dedere, ut nullus repertus sit medicus, qui in Galeni Anatomicis voluminibus vel levissimum quidem Japsum deprehensum esse, multoque minus deprehendi posse censuerint. Vesalius in dedic. lib. de Fabric hum. that all his followers implicitly submitted to his Anatomical relations without further Enquiry, and taught his Errors for truths: And perhaps a certain vanity seized Galen to contradict the famous Herophilus out of dissected Apes, thereby to raise his own credit. However it was, from him arose most of the mistakes in Anatomy, that were translated to the Moors, and from them to our Ancestors. The Moors are said by their Religion, to forbid the meddling with dead bodies: Which Assertion, how true it is, I know not, because that Avicenne and Albucasis commend the study of Anatomy, as necessary in a peculiar manner to Surgeons. They practised sundry Chirurgical operations in Cauteries, and opening Arteries, which seemed to require an Experimental skill in dissections; and which were their own inventions. In fine, Averro pleads not any scruples of Religion for his ignorance in Anatomy, but laments the Civil Wars of the Moors, which hindered him from enquiring by dissection into those controversies betwixt Galen and Aristotle, which he had occasion to debate. Yet did Averro at all adventures, assert the credit of Aristotle against Galen, out of an emulation against Avicenne who was a Galenist. From these two great men amongst the Moors, as the knowledge of Physic and Philosophy, happened to be imparted to the barbarous Christians of the West, so was there a ●eud propagated betwixt the Philosophers, and the Physicians▪ and the controversies were the more intricate, because the Sciences had not been so well translated out of Greek into Arabic, as was requisite; and they were worse put into Latin. After the taking of Constantinople by the Turks, when some learned men had fled thence into Italy, they began to impart unto the world new books, to acquaint the West with the Greek tongue, and with the Greek Works of Hypocrates, Aristotle, and Galen; and thereby multiplied many Controversies in the practice of Physic, about Phlebotomy, and Purging, and the like; especially about bleeding in a Pleurisy, on which side it should be done. The contention was fierce, and some proofs being fetched out of Anatomy, some persons were excited to inquire into humane bodies dissection, thereby to determine this controversy, and also the others betwixt Aristotle, Galen, and others. Amongst these Vesalius was (I had almost said) the first and principal, and by his indefatigable pains prevented much the industry of others. After him Fallopius and Eusiachius were the most remarkable; though many others came in with their little inventions to make up the cry, and failed not to supply the inutility of their discoveries with excessive clamour. What Apologies were made for Galen by Silvius, and others, would be tedious to relate; Yet neither are all the exceptions made by Vesalius against Galen allowable. Ga●●num aliquando in verbis potius quam in ●ententiis carpit, aliquando mutilum (quod sacere debuerat) minime excusat▪ ac saepe indignius, quam Anatomieum▪ Philosophum, ac Medicum tam insignem ●eceret, carpit at accusat. Fallopius observat. ana●om. p 3. they being so ridiculous, and repugnant to common sense, that nothing could stop the growing glory of Vesalius and his followers. The issue of all was, that as Hypocrates lost no credit by an ingenious confession of his mistake about the Sutures in the head of Autonomus; small errors being not observable in great Authors: So Galen still retained a great repute in the world, his other Works having advanced him above the effects of petty calumnies, or defaults. And the great Guinterus And●maeus, a competent Judge of old and new discoveries in Physic and Anatomy, gives this censure upon those curious Disquisitions: De vet. & nova med comment. 8. dial. 5. p. 261. Multa in rerum natura extant, quorum notitia non quidem Medicum aptiorem▪ facit, sed medicinae tantum profectum reddit, Sic nulli ob accuratam illam, ne dicam curiosam nimis, partium corporis perscrutationem Medici excellentiores, sed ob curationes dextre sentatas absolutasque censentur. Ideo etiam Hypocrates, Galenus, Erasistratus, & plures id genus alii, tantum ex rerum natura & corporis humani fabricatione scrutarivoluerunt, quantum ad medicinam probe exercendam ex usu esse putarunt. Non eadem enim semper omnibus similem ob causam conducunt. Sic Anatome aliter physicis inseruit, qui disciplinas ipsas propter se amant; alterii, qui illam non adeo affectant, sed nihil temere a natura factum esse demonstrant: aliter his qui argumenta (ut ille ait) ad actionem quandam vel naturalem vel animalem cognoscendam, ex partium humani corporis historia adferre nituntur: aliter medico qui manum aculeis, telonumque cuspidibus probe exprimendis vel alicui parti apte excidendae vel sinubus & fistulis & abscessibus incidendis adhibiturus est; quo Anatomes usu nihil aeque est necessarium. Certainly it had been an action of greater ingenuity in our Novelists to have acknowledged the many excellent things that are in Galen, which are so advantageous to Physic, then to endeavour to render a man multi ingenii multaque nihilominus habiturum, contemptible by the representation of a few defects in him, relating to things not much material to his profession. It must always be said of Galen, that he was the man who by his dextrous wit, happy practice, and great eloquence, as well as universal learning, did restore the glory of the Hippocratical Physic, which was in a manner extinct in his days. He again brought Anatomy into request, which had been slighted and dis-used so long: he himself dissected bodies privately, and publicly in the Temple of Peace; and amongst other Discoveries of his own, it is observable that he found out the use of recurrent nerves, whose Vide Columbum Anat. l. 14 & Vesalium de fabrica corp. hum. l. 4 c. ●. influence upon the voice is such, that as they are pressed or cut into two, so a Dog becomes perpetually mute, or only howls, never barks. Had that curiosity been but the discovery of some Novelists, what a noise would they have made? what boastings should we have had? But all that is good in Galen is passed by, and to make way for the glory of our new Inventors, Vesalius, Fallopius, Carcanus, Eustachius, Ingrassias, Columbus, Arantius, Varolius, are not so much as mentioned by Mr. Glanvill; to the end that we may (if we will) believe that it is the genius of this Age alone, which puts men upon discoveries, and that before them there were none that had merited this remark. I instance in the most remarkable of their discoveries Plus ultra, pag. 13. Riolanus asserts the first invention of the Valves in the veins to Hypocrates. Anthropogr. l 5. c. 49. briefly: and those I take notice of are, The valves of the veins, discovered by Fabricius ab Aqua pendente: The valve at the entrance of the Gut Colon, found as is generally thought by Bauhinus.— I cannot think these to be so remarkable discoveries, but that he might have found out many more, since the time of Vesalius, I shall name one woe gave a great light to the Circulation of blood, and that is the discovery which Realdus Columbus made, that the blood did pass through the Lungs out of the right ventricle into the left, and so into the Aorta, and all the body. As for the valves in the veins, I believe there are few that think that Fabricius ab Aquapendente, was the first discoverer of them: for they were showed to Fabricius by father Paul, that famous Venetian Monk, as appears in his life written by Fulgentio, and extant in English. Neither indeed was Father Paul the first Inventour of them, for they are described before by Jacobus Silvius, Professor of Physic at Paris, as Riolanus, and Riolanus Anthropogr. l. 5. c. 49.

And as to the valve in the beginning of the Colon-gut (if there be such a one, and that it be not rather a protuberant circle, arising from the joining of the Ileon and Colon, as Pavius, Falcoburgius, and Riolanus hold) whatsoever it be, it was discovered by Varolius, and called the Operculum Ilei, before that ever Bauhinus was born, as Riolanus doth demonstrate: there are two others that may as justly pretend to it, to better merit the credit than Bauhinus, and those are Solomon Albertus, whom Bartholin inclines unto: and Joannes Posthius of Montpelier, whom Riolanus also favours. The Sinus of the veins, and their use found out by Dr. Willis— I wonder Mr. Glanvill should not acquaint us with those particular Sinus which Dr. Willis should find out; for since in common discourse, when we speak undeterminately of the Sinus, we understand those of the brain, it did become him to tell us which others he meant: lest a man that knew his skill, should apprehend him so ignorant as to think that Dr. Willis had newly found out those Sinus, one whereof hath for above two thousand years born the name of Herophilus, and was called Torcular Herophili, in Greek 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉. But I shall Dr. Willis de cerebro c ●. p. 82, 83. be so favourable as to think that these are not the Sinus he meant, Dr. Willis having tried nothing more in prosecution of them, then to pursue the Circulation of the blood there by the injecting of Inkish liquor, whereas Wepferus used a tincture Jo. Jac. Wepferus Apoplex. p 116. Bartholin. Anat. l. 3. c. 7. of Saffron; and Bartholin evidenced the same thing by a pair of bellows, or tube and wind insufflated. I do believe that He, or they that suggested this to him, did mean the Sinus or venae vertebrales, which are described exactly in the Doctor's Book, in the thirteenth Table. But I must tell him, that whatsoever there is in that Piece, which is Anatomical, the glory thereof belongs to Dr. Lower, whose indefatigable industry produced that elaborate Treatise; and any man that knows the great practice of that other Doctor, will grant, that although he could not want abilities, yet he wanted leisure to attend to such painful and tedious inquiries. Dr. Willis indeed candidly doth relinquish this honour to Dr. Lower, and his pains deserved your commendation (Mr. Glanvill) if that be of any value, so much more than those other inventions that are celebrated by the Virtuosos, by how much the subject was more minute and subtle which he was to trace. All that Dr. Willis contributed, that I hear, was the discourses and conjectures upon the Anatomical deductions of Dr. Lower, which as ingenuous as they are, I am sure neither are, nor ever will pass all for inventions. But in the case I now mention, I am confident that Dr. Lower is so ingenuous, asto acknowledge that what He exhibits there, is taken out of the Cuts of Varolius, as far as where they empty themselves into the subclavian veins: but I think that as to the Synus, or veins, and arteries all along the Spine, as there is not any Cut of them extant before that I hear of, so I allow them to pass as his invention: but the accurateness of his Neurology equals to the best Inventors. But if Mr. Glanvill injured Dr. Lower in attributing what he invented unto Dr. Willis, he will 〈…〉 l his own discoveries, you shall see what a Divine can d● in Physic. ' St. Saint"! I add the origination of the Nerves, which were of old supposed to arise out of the substance of the brain, but are found by late Anatomists to proceed from the medulla oblongata. This is such an Addition as becometh our novelists, most that they pretend unto being no more then▪ Mr. Glanvill here boasts of; and which is so pitiful an accessional in Anatomy, that none ever bragged of it, or upbraided the Ancients about it, that I remember, except Bartholin may be said to do it. As to the late Anatomists, unto whom he ascribes this invention, I would he had told their names. The difference betwixt the cerebrum, cerebellum, and medulla oblongata, is a modern (but not very late) distinction. Some have made the medulla oblongata and the spinal marrow to be but productions of the brain and cerebellum, from whence it raiseth itself by four foundations or roots: the discrepancy betwixt that and the other parts whence it is originated, not being such as to justify any great contest about it: since it is the usual course of Nature in its progress from the union of two different bodies, to produce an intermediate substance, participating of the nature of both. Spinalis medulla ortus principium rectius cerebro atque cerebello Vol. Coiter. observ. anatom miscel. Ex substantia cerebri & cerebelli quatuor radicibus oritur primum troncus insignis, Medulla spinalis appellatus, ex quo multi emergunt surculi, nomine nervorum insig●iti. Varolius Anatom▪ l 1. c. 13. ● 12. acceptum fertur, unde non immerito caudex, sive processus, sive soboles cerebri appellatur: nam vix in ullo, nisi in duritie (est enim cerebro aliquanto solidior & firmior) videtur a cerebro differre. Some have made the brain & cerebellum to be productions of the spinal marrow, which enlargeth itself within the skull, and generateth those two Apophyses called the cerebrum & cerebellum. In fine, it doth not appear that the Ancients mistook much the place of the origination of nerves, if you reckon amongst them Vesalius and Fallopius: but they said they rose all from the brain, understanding by that word all that which is included within the skull, and termed that to be the spinal marrow, which was without the skull, and whence those other paria nervorum seem to rise, which Anatomists describe. And this subtlety of Mr. Glanvill is so little regarded by late Anatomists, that Moebius (a man of as great note as most are) slights it Moebius fundament med. c. de usu nervor. p 606. Caspar Hoffman. ins●●t. med. l 2. c. 65. sect. 1. by the example of Hoffman, whose sense I shall here report: Monendi sunt adolescentiores, ne forte morentur illos qui neglecta veteri distinctione dicunt, Omnes nervi sunt a medulla, sed alii ex illa, antequam cranio excidat, alii ex eadem, cum jam in spinam delapsa est, & Spinalis dicitur. Quid enim hoc aliud est, quam frustranea nominum So Dr. Charlton in his Discourse to the Royal Society concerning the Brain, takes the liberty to understand by the Cerebrum as well as others, totum illud corp●● quod Calvariae concavo continetur (pag. 67. de Propr. cerebri humani) though afterwards, when he comes to speak more accurately, he treats of the Medulla oblongata thus: Cerebro proxime subjicitur alma nervorum ad sensus spectantium mater, & funis argentei (sicut Sapiens in Ecclesiaste eleganti sed obscu●a Allegoria vocat Medull●m spinalem) principium Medulla scilicet intra cranium oblongata. Behold the addition of Mr. Glanvill! novatio? Cum dico me de nervis ex cerebro ortis acturum, intelligo totum id quod cranio continetur. There is another Origination of the nerves, which is as ancient as Aristotle, and which Hoffman and Ʋander Linden assert, whereby they are deduced immediately and formally from the brain, but immediately and materially from the heart; for so much as they hold each nerve to be an Artery vested with the membranes of the brain, and so issuing to several parts. This opinion is very agreeable to the observations that occur in the practice of Physic, and their arguments seem to me so plausible, that I am so averse with Mr. Glanvill to proclaim a new origination of the nerves, that I much doubt whether the followers of Galen were not deceived, and the Peripatetics in the right. See Ʋander Linden Disp. 38. de vasis & nervis, and Hoffman de partib. similar. in thes. de orig. nerv. sec. Aristot. It is clear now that Mr. Glanvil●s new addition amounts only to this, that the Ancients did some of them hold that the nerves had their original from the brain; others deduced Vide Varolium l. 1. c. 3. them from the heart. Some (perhaps before Varolius) did subdivide the brain into several parts, If Varolius found it out, as I believe be did, by a peculiar way of dissecting the head, what is it that Mr. Glanvill then ●DDS? I am sure that Fracassatus saith, Varolius primus principium spinalis medullae vel intra cranium sobolescere in nervos, quorum origo olim á cerebro petebatur, docuit. and said that the nerves had their origination from the medulla oblongata, and not from the cerebrum and cerebellum. This nicety Dr. Willis makes some use of, but since he explicates nothing of the brain with a mechanical accurateness; I shall only subjoin, that whosoever shall view or eat that which they call Medulla oblongata & spinalis, and compare it with the marrow that is in the bones otherwise, he will think it a less impropriety of speech, to say the Medulla oblongata is a part of the brain, then to term it a Medullary substance. And though the Succus Nutritius be not yet fully agreed upon by Physicians, yet it hath so much to say for itself, that it may not unreasonably be mentioned amongst the new Inventions— It's strange Mr. Glanvill should entitle this opinion about the Succus Nutritius to so great a degree of probability, as he doth. Physicians are so far from being fully agreed upon it, that, excepting Dr. Glisson, Dr. Charleton, and perhaps one or two more, the rest do generally reject it. Highmore de affect. hypochondr. c. 4. Willis in Anatome cerebri c 20. Bartholin spicileg. 1. c. 3. Dr. Highmore, Dr. Willis, and Bartholine have written against: it; and so hath Deusingius writ a particular discourse against: it. Nor do I doubt, but whosoever peruseth those Authors which I refer unto, will be so far from imagining it reasonable to ascribe the Succus Nutritius to the number of modern Inventions, that he will term it at best but an ingenious Paradox, which when the first surprise is over, vanisheth with the appearance of being ridiculous. How much doth our Virtnoso, and Bartholine differ? Prodeat Herophilus, ex Bartholin. spicileg. 1. de vasis lymphat p. 23. autro educatur Democritus, advocentur prosectores cujuscunque sortis & aetatis, si in dissectis corporum nervis ullum invenerint liquorem nutritioni opportunum, nolim inter eos locum mereri. But of all Modern Discoveries, Wit and Industry have Plus ultra, pag. 15. made in the Oeconomy of humane nature, the noblest is that of the Circulation of the blood, which was the invention of our deservedly famous Harvey. 'Tis true, the envy of malicious Contemporaries would have robbed him of the Glory of this Discovery, and pretend it was known to Hypocrates, Plato, Aristotle, and others among the Ancients; but whoever considers the expressious of those Authors, which are said to respect the Circulation, who find that those who form the inference, do it by a faculty that makes all kind of Compositions and Deductions, and the same that assists the Enthusiasts of our days, to see so clearly all our alterations of State and Religion, to the minutest particulars in the Revelation of Saint John. And I think it may be as well concluded from the first chapter of Genesis, as from the remains of those Ancients, who if they had known this great and general Theory, how chance they speak no more of a thing, which no doubt they had frequent occasions to mention? How came it to be lost without Memory amongst their followers, who were such superstitious Porers upon their Writings? How chance it was not shown to be lodged in those Authors before the days of Dr. Harvey, when Envy head impregnated and determined the Imaginations of those who were not willing any thing should be found anew, of which themselves were not the Inventours? But 'tis not only the remotest Ancients, whom time hath consecrated, and distance made venerable, whose Ashes those fond men would honour with this discovery; but even much later Authors have had the glory fastened upon them. For the Invention is by some ascribed to Paulus Venetus; by others to Prosper Alpinus; and a third sort give it to Andraeas Gaesalpinus. For these, though either of them should be acknowledged to be the Author, it will make as much for the design of my discourse, as if Harvey had the credit: and therefore here I am no otherwise concerned, but to have justice for that excellent man: and the World hath now done right to his Memory, Death having overcome that Envy which Dogs living virtue to the Grave; and his Name rests quietly in the Arms of Glory, while the Pretensions of his Rivals are creeping into darkness and oblivion. Whether those that have gone about to deprive Dr. Harvey have been incited by Envy and Malice, it is hard for any considerate man to judge; since those which first proposed the doubt about the Author, were great friends to the Theorem; such as Walaus, who first mentioned it; Riolanus, Nardius, Fracassarus, and Joannes Antonides Ʋander Linden: All of them pay a great respect to Dr. Harvey's Performances; All of them concur with him generally in his Assertions, saving that Riolanus made some variation therein, and perhaps his passion might blind his candour; though I do not think so, because I find him zealously vindicating of Dr. Harvey from those imputations by which Walaeus endeavoured to transfer the credit of the invention upon Father Paul. Another thing I must take notice of is, that Mr. Glanvill speaks very peremptorily about a thing he hath not enquired into, for it is evident that he never read the passages out of the Ancients, which are cited by Walaeus and Riolanus, to to show they were not altogether ignorant of that motion of the blood which is called Circulation. He thinks it may be as well concluded from the first chapter of Genesis, as from the remains of the Ancients. And why so? Is there any thing mentioned in the first chapter of Genesis, that sounds like the Circulation of the blood, or any words that can be applied unto this late discovery? not one. But any man that understands Greek, must confess that the words 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉, and 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉. in Hypocrates (whatever he meant by them) do most emphatically signify the Circulation of the blood, as it is now proposed. If I merit not to be believed herein, take the judgement of Julius Caesar, Scaliger upon Aristotle de insoma. xiij. 1444. 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉. I shall not from this place deduce the mystery of the Circulation of the blood, by saying that rivers circulate under ground through that sandy earth, which those that dig in Wells, when they come unto, they can descend no further: (which Helmont in the Brabant Dialect calls Quellem, other Dutchmen name Well-ground and Wellsand, and after return unto the Sea again by open Channels: But whatever the intent of the Philosopher was, that 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉, properly imports such a thing, and that we have the name given it by Aristotle, this Scaliger confesseth, Ejus ad apotelesma xxxi. haec sunt verba.. 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 motum; ut infebribus accessionem. Circuitum Calvus cum dicit, fideliter, non pleno explicat. Neque enim. circumducitur sanguis, ut 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 impleat significationem Nam in febribus idcirco dicitur 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉, quia revertitur paroxysmus: quasi circumductus ob diem parum & vacuum a morbo. From which it is evident, that if Scaliger had known that the blood had circulated, he would have granted it to have been properly expressed here in the Text: which is more than He would say of any Apocalyptical discoveries, or deductions of that opinion out of the first Chapter of Genesis. And if the word 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 be so significant, it is hard to deny that Hypocrates did not set down the thing itself in this passage, 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉, Hypocrates de oss. nat. t. 17. 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉. Venae per corpus fusae spiritum, & fluxum, & motum praestant. Ab una multae propagantur: sed illa una unde incipiat, aut ubi desinat, non scio. Circulo enim ducto, principium non invenitur. And in that other; 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉- E● lib. de alim. t. 4. 1●. 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉. In pilos alimentum [id est, sanguis nutriens] & in ungues, atque extremam superficiem intus advenit: faeris alimentum ab extrema superficie intime revertitur. Corrivatio una, conspiratio una, consentientia omnia. Certe quod ad communem naturam omnia: in quavis parte partes ad opus. Principium magnum [id est Cor, per transmissos spiritus & sanguinem] ad extremam partem pervenit: ab extrema parte ad principium magnum revertitur. There are more passages in the same Author which seem to import the same thing, though his usual brevity and obscurity is such, that had not Harvey and others dilucidated the point, we had never, I believe, fixed this explication upon him, which amounts to no more than a new gloss upon an old Text: which yet is sufficient to check the largeness of Mr. Glanvills' assertion. The 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 of Plato, and his making the Heart to be the original of the veins, 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉; Plato in Timaeo. these are something more than is to be found in the first of Genesis. And that passage of Aristotle de Gen. Anim. l. 4. c. ult. is so unlike any thing of Moses', and so like to the doctrine of Harvey, that any man must blame Mr. Glanvill, for rashness of what he says. The words are thus set down by Riolanus, and I have not the Original by me to consult: Cum coelestia corpora circulariter moveantur, inseriora ' corpora motum illum imitari debent, cumque Oceanus fluxu & refluxu moveatur ab influxu Lunari, similiter humores talem motum habere necessum est. Which words seem clear enough, so as to justific the Epiphonema of my Author, in opposition to our Virtuoso. Quid ista significant nisi sanguinis Circulationem. He that would be informed more fully about the judgement of the Ancients, whether there be any thing in them that discovers the Circulation of the blood, to have been known unto them; or that they were not totally-ignorant, and without any apprehensions of it: let him read the first letter of Walaeus, and the several Pieces of Joannes Riolanus about the Circulation of the blood, and the disputations of Ʋander Linden about the Circulation of the blood, in which he vindicates it in a prolix discourse unto Hypocrates. I will not trouble my self to transcribe them: It is evident that all men do give unto Harvey the credit of having so explicated it, and Anatomically proved it, that he may as well be termed the Author of it, as Epicurus and others the Authors of that Philosophy which they derived from Pythogoras, Democritus, Leucippus, and Ocellus Lucanus. Nor hath Harvey any other Plea and Right to the Invention, then that he did more fully and perspicuously declare it, and in the most judicious and solid manner assert what others had but hinted at, or fainily insisted on. Nor is Mr. Glanvill any better acquainted with the notions of the Modern Writers, than he is with those of the Ancients. He saith, that some have ascribed the Circulation of the blood to Paulus Venetus. I must inform the Reader (who may easily mistake, if he be one of the ordinary Comical Wirs) that it is not to be ascribed to Paulus Venetus, the great Traveller, who is generally understood, when that name is mentioned; none can say that he brought it from the Kingdom of Cathay. But Pater Paulus Sarpa (or Serpa) or Father Paul, the famous Venetian Monk, of the order of the Servi; who signatised himself during the time that Venice was interdicted. He was a Student at Padua at the same time that Harvey was there, and discovered to Aqua pendens the valves in the veins, which discovery that great Anatomist appropriated to himself; and so Harvey was thought to have abused the same Father. But since Fulgentio in the life of Vide Slegel. de motu Sanguine c. 2. & Riolan. in not. ad ep. Walaei. Padre Paolo doth not challenge Harvey for this Cheat, as he doth Fabricius for that other; and since Marquardus Slegelius could not hear of any such thing upon a strict Enquiry at Venice and Milan, I know not any since Walaeus and Franciscus Ulmus, that have ascribed the invention to Paulus Venetus Servita. Neither did I ever read of any man that attributed it to Prosper Alpinus: nor is it credible that any ever did so. For that great Physician established his glory by being an excellent Practitioner, and not by any Anatomical curiosities, which he rather contemned, then pursued: and till I know what Author Mr. Glanvill follows, I believe the mentioning of him was occasioned by that way of discoutses which is common to the Wits of this Age, to blunder out any thing: and by laughing at improbabilities (of their own suggestion) to explode substantial truths, or represent them as forgeries. But if any did deceive the world in attributing the Circulation of the blood to Padre Paolo and Prosper Alpinus, it doth not follow but that Andreas Caesalpinus was the first Inventor of it, and proposed it to the world in his Medical and Peripatetical Questions, thought not in any Set Discourse, but as it casually falls into the discussion of other Problems: Whereupon it was little regarded, and not enquired after; the book being also scarce, and he being of that faction of Physicians which adheres to Aristotle against Galen, whence it happened that few read his Paradoxes, and one of the bravest men of the latter Age hath been almost buried in oblivion. However, an ingenious Florentine, called Joannes Nardius, hath asserted the repute of Andraeas Caesalpinus, for precedency to Harvey in the Discovery; nor doth the same Author doubt, but that Erasistratus was of the same opinion: but he saith of Caesalpinus this: Foelix cui contigit post mortem nancisci clarissimum Patronum Guglielmum Harveium Regium Medicum, nobisque per charum, qui abortivam illam opinionem excoluit adeo, ut nihil cultius nostro seculo, nilque mirabilius occurrerit curiosis & amaenarum literarum amatoribus. To decide this question▪ and to put an end to those disputes which trouble some of our Virtuosos so much, by reason of that little converse they have with Books, I shall draw out the opinion of Caesalpinus, as he expresseth himself in his Disputations. As a great abettour of Aristotle, he avows that the Heart is Andraeas' Caesalpinus Qu. peripatet. ●. 5. qu. 3. the principal part in man, and the original of the veins, arteries, and nerves; which is the opinion of Hoffman, Van der Linden, and other Aristotelian Physicians. He describes the Fabric of the Heart as exactly as any of the Circulators in reference to the Valves, so much talked Ib. qu. 4. of; but he declares not their shape: Vasorum in Cor desinentium quaedam intromittunt contentam in ipsis substantiam, ut vena Cava in d●●tro ventriculo, & arteria venalis in sinistro: quadam educu● ut arteria aorta in sinistro ventriculo, & vena arterialis pulmonem nutriens in dextro: omnibus autem membranule sunt appositae & officio delegatae, ut oscula intromittentia non educant, & educentia non intromittant. And for the account of the Vena arteriosa, and Arteria venosa in the Lungs, Harvey is not more perspicuous, than he is afterwards, where he makes the one to be an Artery, the other a vein, viz. Putaverunt autem Medici usum hunc non videntes commutatae fuisse vasa in pulmone, ut Arteria quidem similis esset venae, vena autem similis Arteriae: appellantes venas vasa omnia quae in dextrum ventriculum desinunt, Arterias autem, quae in sinistrum: figmenta multa & absurditates excogitantes ut usum invenirent. Pulsat igitur in pulmone vas dextri ventriculi, haec enim e corde recipit, ut Arteria magna, & similiter fabricatum est ejus corpus. Vas autem sinistri ventriculi non pulsat, quia introducit tantum, & ejus corpus simile est reliquis venis. He holds that the motion of the Heart and Arteries depends not upon any pelsifick Faculty, but that it ariseth from the 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉, ebullition, or effervescency of the blood in the Ventricles; and that the Heart and Arteries are dilated at the same time, the blood dilating the Heart, and issuing out through the valves of the Aorta and Pulmonique Artery at the same instant, which is pure Cartesianism. He holds that the Blood comes up from the veins to the Heart, and there acquires the last Perfection, and becomes vital and spirituous: in the mention of the Arterious Blood, he useth indifferently the terms of Blood, spirit, and natural heat, which I desire may be observed, lest the proofs seem not full enough, and he be construed to speak of nothing but spirits and natural heat in the Arteries. He saith, that this Blood having acquired its Perfection in its passage through both the ventricles, is distributed through all the parts of the body, for its nutriment by the Arteries, in which Arteries there is such a constant quantity of Blood, that the effervency of that in the Heart impells the whole continuation of the Arteries, so that they beat all at once. Cum enim pulsatio Cordis & Arteriarum sit accidens quoddam quod ex necessitate insequitur humoris in cord effervescentiam, qua sanguinis generatio per ficitur, ut in caeteris quae igne elixantur, accidit. lib. de vita & mort. c. ●. intumescente corde necesse est simul omnes Arterias dilatari, in quas derivatur fervour: non enim repleri potest una pars, quin totum fiat majus: ubi non omni ex parte vasa quae continua sunt fuerint exinanita. Name nullo intus existente corpore, non contingit simul repleri principium & extrema, cum motus non fiat in instanti: existente autem per totos canales aliquo spiritu, simul ac in principio alius fuerit genitus, necesse est totum simul dilatari, unum enim sit spiritus accedens cum toto. Cum ergo totum reddatur majus simul ac accesserit pars, non potest una pars dilatari, quin eodem tempore dilatetur totum. Est autem veluti totum quoddam Arteriae omnes cum cord; Mark this, where he makes the Heart and Arteries to be one continued recepracle of perfect blood: by which you must explain what he says in some places, as it only spirits or natural heat went into the Arteries, or returned by the veins. Continuum enim est vas sanguinis perfecti. Spiritu autem efflante inhabitum corporis, & distributo particulis sanguine, necesse est tumorem vasorum desidere, quae est pulsus contractio. Continue autem hoc fit, quia continua est partium nutritio, & continua sanguinis generatio in cord. Elevatio igitur Spiritus a calore fit, non tamen temere, sed alicujus gratia. Nam sine hujusmodi amplificatione non fieret distributio alimenti in omnes parts. He plants a kind of Flammula cordis, or fire in the heart, which causeth the ebullition, and imprints a spirituousness in the blood that issueth out into the Arteries. Hujusmodi loc●s Cor est in quo secundum Naturam elementum praeparatum ardere possit, & fieri spiritus: venae alimentum suppeditant, Arteriae flammae spiritum recipiunt. He saith, that the Blood moves towards the Heart, as the Oil to the flame of the burning Lamp, and that the Valves as the orifice of the Vena Gava which immit the blood, are placed there to moderate the source of the blood, lest it should fall in too fast, & extinguish the vital fire: and that the valves at the entrance of the Aorta do fly open upon the effervescency of the blood, by the pressure of it every way, to get more room: it finding no outlet but by those yielding valves, which were so placed, lest upon any accident, or viclent passion, the arterious blood should regurgitate into the Heart, Motus fit ex venis in Cor caliditate alimentum trabente, ex corde autem in arterias, quia hac solum patet iter propter membranarum positionem, positae autem sunt hoc modo membranae, ne unquam contingeret contrarium motum fieri, quod accidere posset in vehementibus animi perturbationibus, aut aliis causis, a quibus sanguinis retractio fit ad Cor: Obsistunt enim huic motui membranae. Nam si hoc modo condite non essent, ignis cordis vel levi causa extingueretur. Si enim metus fieret contrarius simile esset, ac si flamma compingeretur deorsum ad alimentum, quod cum minime sit praeparatum, aut cepiosius quam oportet, ignem suffocat. Oportet enim alimentum praeparari, & paulatim dispensari ad locum flammae. He saith that this arterious blood, or spirit, is distributed into all parts of the body, with great celerity, and that it is that which nourisheth the parts: and that upon its diffusion into the habit of the body, the spirits are very much exhausted, and the corpulent part of the aliment doth remain, being coagulated partly by heat, and partly by cold. He saith, that the variety of the pulse, as to strength or debility, celerity and slowness, depends upon the nature of the vital fire, the nature of the aliment with which it is fed, and sometimes upon the particular Fabric, or conformation of the Heart, in which that Fire is seated. He placeth anastomosis betwixt the veins and arteries every where in the body. Osculorum communio est non solum in cord, sed etiam per totum venerum & arteriarum ductum, He saith that the blood is never extravasated, but where it is aggregated to any part by way of nourishment, or else it putrifies: he doth not understand how it should not coagulate if once extravasated; nor can he comprehend how it should be reassumed into the veins in such a case. Venam continuam esse oportet, usque ad cordis ventriculos, ut inde omnis virtus descendat: nec ullibi contingit disjunctam esse; sanguis enim calore cordis destitutus concrescit, & tandem putrescit. He makes the Blood to pass betwixt the right and left ventricle of the Heart; partly by the Lungs, and partly by the Septum Cordis. Pulchre igitur condita sunt omnia. Cum enim fervere oporteret in cord sanguinem, ut fieret alimenti perfectio: primo quidem in dextro ventriculo, in quo crassior adhuc continetur sanguis, deinde autem in sinistro, ubi sincerior sanguis est: partim per medium septum, partim per medios pulmones refrigerationis gratia ex dextro in sinistrum mittitur. Interim autem pulmo abunde nutriri potest: totum enim eum sanguinem absumere, quem recipit, egreditur fines rationis. Non enim rara esset ejus substantia & levis, ut videtur si tantum alimenti, vim in suam naturam converteret. This he thus further explains. Pulmo per venam arteriis similem ex dextro cordis ventriculo fervidum hauriens sanguinem, eumque per anastomosin arteriae venali reddens quae in sinistrum cordis ventriculum tendit, transmisso interim aere frigido per asperae arteriae canales, qui juxta arteriam venalem protenduntur, non tamen osculis communicantes, ut putavit Galenus solo tactu temperate. Huic Sanguinis Circulationi ex dextro cordis ventriculo, per pulmones in sinistrum ejusdem ventriculum optime respondent ea quae ex dissectione apparent. Nam duo sunt vasa in dextrum ventriculum desinentia, duo etiam in sinistrum. Duorum autem unum intromittit tantum, alterum educit, membranis eo ingenio constructis. Vas igitur intromittens, vena est magna quidem in dextro, quae cava appellatur: parva autem in sinistro, ex pulmone introducens, cujus unica est tunica, ut caeterarum venarum. Vas autem educens Arteria, est magna quidem in sinistro, quae Aorta appellatur, parva autem in dextro ad pulmones derivans, cujus similiter duae sunt tunicae, ut in caeteris arteriis. He holds that the spirituous or arterious blood is cast ou●, and diffused vigorously into the habit of the body, that the veins and arteries being continuous by Anastomosis, it returns to the Heart again, vigorating the blood of the vena peria and Cava as it returns: which is sufficiently intimated in that he deduces all the vigour and vitality of the blood from the Heart, and that this vigour or natural hear is carried over the body by the Arteries alone, and that it is necessary that the whole venous Systeme, or contexture of Arteries and veins be continuous, lest the blood in the veins, being destitute of the cordial heat, should coagulate and putrify. He holds that this motion, or Circulation of the blood is without intermission: and that the swelling▪ of the veins upon the Ligature is a sufficient proof of it. But he holds, that the recourse of the blood by the veins is greater in the sleep, then when we awake; which he proves thus, in that the veins are more full and tumid during sleep, then waking: and the pulse weaker, and more slow; as any man may observe. From whence he concludes, that the natural heat (which is the Arterious blood, as I observed before, to prevent all possible mistakes) which was otherwise in great part expended upon the nerves and sensories, doth in sleep return: and fill the veins more visibly (that exhaustion ceasing) then when we are not asleep. His opinion will be best set down in his own words; and I think it necessary to do it, because Nardius hath done it so imperfectly, that one would attribute as little to his allegations, as to those which are cited out of the Ancients; and if I had not read Caesalpinus long before, I should have thought the Florentine to have entitled Caesalpinus to the opinion out of envy to Harvey, or out of a partial desire to advance the glory of the Tuscan Academy at Pisa, when Caesalpinus was Professor. Thus that learned man writ about the year 1590. or a little after. Andraeas' Caesalpinus Quest▪ Medic. l. 2. Qu. 17. edit. venetae secunda in 4 to. A. D. 1593. fol. 234. col. 1. Sed illud speculatione dignum videtur, Propter quod intumescunt venae ultra locum apprehensum, non citra: quod experimento sciunt qui vena secant: vinculum enim adhibent citra locum sectionis, non ultra: quia tument venae ultra vinculum, non citra. Debuisset autem opposito modo contingere, si motus sanguinis & spiritus a visceribus fit in totum corpus: intercepto enim meatu, non ultra datur progressus: tumour igitur venarum citra vinculum debuisset fieri. An folvitur dubitatio ex eo quod scribit Aristoteles, the Some c. 3. ubi inquit, Necesse enim quod evaporatur aliquousque impelli: deinde converti & permutari, sicut Euripum: calidum enim cujusque animalium ad superiora natum est ferri: cum autem in superioribus locis fuerit, multum simul iterum revertitur, ferturque deorsum. Haec Aristoteles. Pro cujus loci explicatione illud sciendum est: Cordis meatus ita a natura paratos esse, ut ex vena Cava intromissio fiat in Cordis ventriculum dextrum, unde patet exitus in pulmonem: ex pulmone praeterea alium ingressum esse in Cordis ventriculum sinistrum, ex quotandem patet exitus in Arteriam Aortam, membranis quibusdam ad ostia vasorum appositis, ut impediant retrocessum: Sic enim perpetuus quidam motus est ex vena cava per Cor & pulmones in Arteriam Aortam: ut in Quaestionibus Peripateticis explicavimus. Cum autem in vigilia motus caloris nativi fiat extra, scilicet ad sensoria: in Somno autem intra, scilicet ad Cor: putandum est in vigilia multum spiritus & sanguinis ferri ad arterias, inde enim in nervos iter est. In somno autem eundem calorem per venas reverti ad Cor, non per Arteriam.

Num in Somno calor nativus minus vergit in arterias: in casdem erumpit vehementius cum expergiscuntur. Venae autem contrario se modo habent: nam in somno fiunt tumidiores, in vigilia exiliores, ut patet intuenti eas quae in manu sunt. Transit enim in somno calor nativus ex arteriis in venas per osculorum communionem, quam Anastomosin vocant, & inde ad Cor. Ut autem sanguinis exundatio ad superiora, & retrocessus ad inferiora ad instar Euripi manifesta est in somno & vigilia, sic non obscurus est hujusmodi motus in quacunque parte corporis vinculum adhibeatur, aut alia ratione occludantur venae. Cum enim tollitur permeatio, intumescunt rivuli qua parte fluere solent. From hence it is clear that He held that the blood did circulate continually, falling into the Heart by the vena Cava, and issuing out by the Aorta into all parts of the body: that this motion of the blood was perceivable by the Ligatures at any time, but most manifest in the intumescence of the veins in sleep: at what time also the blood or natural heat (which is all one to him) did pass by way of Anastomosis out of the arteries into the veins, as well as at other times. So that we are not to imagine any interrupted circulation in him, but that it did constantly flow night and day, sleeping and waking, though with unequal celerity. In letting of blood he tells us, that the blood which first issues out is venous, and blacker then that which follows, and comes more immediately Qu. Med. l. 2. qu 5 fol. 212. col. 1. lit. ●. out of the Arteries.— Venas cum Arteriis adeo copulari osculis, ut vena secta primum exeat sanguis venalis nigrior; deinde succedat arterialis flavior, quod plerumque contingit. And Qu. Med. l. 2. qu. 15. fol▪ 230. col. 1. l. c. he explains the motion of the blood, and natural heat thus, to prevent all ambiguity. At instabit quis in somno nequaquam prohiberi calorem in cerebro & sensoriis: pulsant enim arteriae in toto corpore etiam in somno. At praesente calore innato debuisset duci in actum facultas animalis. An calor innatus in somno viget in venis & arteriis, non in nervis sine quibus, non sit sensus & motus? Extra igitur ferri est nervos petere, intra autem non solum ad viscera, sed in omnes venas & arterias; unde operationes naturales magis perficiuntur in toto corpore. I hope I have now determined the Question which hath occasioned so many heats in the world concerning the Circulation of the blood, who was the first Inventor of it? I have demonstrated that Andraeas Caesalpinus, a rigid Peripatetic upon sensible Experiments & Mechanical considerations, not notional apprehensions, did not only discover this motion of the blood (even through the Lungs) but gave it the name of CIRCULATIO SANGUINIS; which name is not so proper in itself, considering the Fabric of the veins and arteries, and the Labyrinth in which the blood moves universally, describing a Line no way circular, as that a man would have pitched upon it in any other Age then when Caesalpinus lived, when the knowledge of the Learned Languages was less general than now, and such a barbarous stile in fashion, as our Inventour used. But it was not so in the days of Dr. Harvey, who published his Treatise in 4 to. at Francfourt in the year (as I take it) 1628. I must confess I am apt to think upon▪ this consideration, that Dr. Harvey (who was a Peripatetique Physician, and in whose time at Padua, those Physicians did flourish with the greatest repute of Learning and skill in Anatomy, as well as Philosophy) did take up this opinion from my Author. And although there wanted not occasion by reason of what Walaeus, Riolanus, Slegelius, and others had said upon the point, for him to declare the original of the discovery, yet in his two Answers to Riolanus, and his Book of Generation, He no where asserts the Invention so to himself, as to deny that he had the intimation or notion from Caesalpinus; but leaves the Controversy in the dark: which silence of his I take for a tacit Confession. His Ambition of Glory made him willing to be thought the Author of a Paradox he had so illustrated, and brought upon the Stage, when it lay unregarded, and in all probability buried in oblivion. Yet such was his Modesty, as not to vindicate it to himself by telling a Lie. And such his Prudence, as rather to avoid the debate, then resolve it to his prejudice. Had Dr. Harvey been a Chemist, I should have guessed that he might have fixed upon the word Circulation, upon other reasons, and those congruous enough to his Hypotheses: but since (especially in the days when he writ) those Studies were Narravit mih.

Let it suffice, that Dr. Harvey had parts and industry enough to have discovered it, had he not been prevented therein. And I should have imagined that our Countryman had found it out, without any communication with those other books (a thing possible enough, and of which we have instance in the case of Rudbek, Bartholine, and Jolice) but that the reasons I have alleged render the case suspicious. Had Caesalpinus writ a distinct Treatise, I doubt not but much of the Glory had been his: since there are as great differences between one Circulator, and another, and greater, then betwixt him and Harvey: but his notions being confusedly laid down here and there in his Peripatetic and Medicinal Questions, and he being not ambitious to pretend to any new discoveries, only to illustrate Aristotle's tenets. I shall allow Harvey the possession of his present repute: nor do I give myself this trouble of collecting up into a method these confused assertions of Caesalpinus out of any envy to the dead, but out of animosity to Pretenders to Wit and Learning, that brave it thus amongst us; yet if to be ignorant of what hath passed in the world heretofore, be an argument of childishness, there is not any thing more puerile than this sort of Virtuosos. I might not dismiss my Reader, but that the great noise which this Circulation of blood makes in the World, enforceth me to speak a little more about the utility of this discovery, which our Author describes to be the most noble of all those discoveries in the Oeconomy of humane nature, which Wit and Industry have made. I do confess I think the Arguments for it to be such as admit of no Answer in general; but when we come to debate how it passeth through the Lungs▪ (which Riolanus almost invincibly disproves) or through the Septum Cordis, (which Riolan and Bartholin asserts, but Harvey, Slegelius, Ʋander Linden, and others, reject it o● good grounds) what it is that causeth the pulsation of the Heart? what continues on the motion of the blood in the veins, even when a Ligature is made betwixt the antecedent and subsequent blood. Whether the blood be diffused into the habit of the body, and reimbibed by capillary veins, or conveyed on by anastomosis? whether there be any difference betwixt the venous and Arterious blood? How the Phaenomena (which undeniably are observed) about the pulse can be made out▪ and particularly how some have lived without any Pulse, others (which I have known) in the palpitation of the Heart, suffer no change in their Pulse? How upon dissection or wounds sometimes both ends of the vein divided do bleed? How some bleed at the arm without any Ligature; some upon a double Ligature? These, and many other questions, when I come to dispute with myself, methinks I am forced to constrain my judgement in the assent I give to that Problem: and what I am ashamed to deny, I find I cannot own without some reluctancy, which is daily increased in me by scruples arising from the Practic Part of Physic; nor do I blush to declare myself an Abettour only of such Tenets, as are consistent with, and illustrated by Practical Physic: it was thought at first that this Circulation of blood would overthrow all the usual Methods of Physic, and introduce new and beneficial discoveries in that part of Medicine which is Therapeutic. But Harvey denieth that it varieth the Medicine of the Ancients; and Slegelius asserts the same opinion, avowing it to be rather an happy illustration, then ● subversion of the former praxis, though it alter the Theory much. In fine, those little advantages and Diorismes, which we derive from that Invention merit not our notice; nay, any man shall with more assurance bleed in many diseases in sundry manners and different places, upon divers indications upon the old observations and rules, then on the new hypotheses, wherein as to the use of parts, and nature of humours, there is as little of clearness and certainty; as there is efficacy it▪ that practice▪ which is regulated most thereby. I had forgot to take notice of the venae lacteae ascribed to Nardiu●. noct G●●al. 4. p 412. Asellius, the invention of them is thought a great discovery, and such as signatiseth a man in this Age. Yet even those vessels were known to Galen, as Nardius proveth out of his book against Erasistratus, c. 5. and out of the last chapter of his Anatomical Administrations. It is true, he calls them Arteries; he saith they were in the Mesentery filled with Milk, and that he observed them in young Kids. And Hoffman in his Variae Lectiones doth produce out of Galen, de usu part. l. 4. sect. 19 a place so evidently showing that Galen and Herophilus did recover those Venae lacteae; that Veslingius cries out in a Letter to him, Existimo aut nihil cum Herophilo Galenum vidisse, aut has 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉, hos Epist xxi. ipsos ductus esse, quos lacteos cum Asellio nominamus.

Which proof as it is perspicuous enough to ruin the discovery of the Venae Lacteae, and the deducing of them unto the Glandules of the Mesentery (beyond which Herophilus and Galen did never trace the journey of the Chyle, but imagined those veins to nourish the Mesentery) so I think that the invention of the Ductus Thoracius belongs to Andr. Vesalius, and Barthol. Eustachius: the one more obscurely proposeth it, the other more openly. Andr. Vesalius de fabrica corporis humani l. 3. c 7. Jo Ant.

Since the writing hereof, I have met with a book containing certain Letters of Márcellus Malpighius, and Carolus Fracassatus; in which it is observable that Fracassatus (the Anatomy-Professour at Pisa) doth ascribe the Invention of the Circulation of the blood to Caesalpinus; and of the ductus Thoracius to Eustachius: His words are these: Adeo oscitantia Autorum quaedam tam male praeponuntur, ac tanguntur, ut oporteat alios eadem repetere, ac ditare novis elucubrationibus, ac si nunquam fuissent. Sanguinis Circulatio, Galaxia in Microcosmo humano, scilicet via Chyli Cor, nun Caesalpinum agnoscit Authorem, ac Eustachium de vena sine pari?

Having said thus much, I leave Mr. Glanvill, to answer those little quillets of his, which can convince none but Shallow-brained and Comical Wits.— If they knew these grand Theories formerly; how chanceth it that they speak no more of things, which no doubt they had frequent occasions to mention? How come they to be left without memory among their followers, who were such superstitious porers upon their writings? How chanceth it not to have been shown to be lodged in those Authors before the days of Dr. Harvey, etc. when Envy had impregnated and determined their imaginations? Let illiterate persons and Mathematicians be swayed against plain proof by these Arguments. I think in stead of Temples and Altars to be erected to these Inventors, there is more need of a Schoolmaster and an Antiquary, the one to teach them humane learning, the other to instruct them in past discoveries; lest, with much trouble and pains our new Philosophers should find out again the Art of Printing, or Etching: the use of Gunpowder, or the Loadstone. Of Transfusion of Blood— into Animals. THus, Sir, I have done with Instances of Anatomical Plus Ultra. pag. 17. Advancements, unless I should hitherto refer the late noble Experiment of Transfusion of the Blood, from one living Animal into another, which I think very fit to be mentioned; and I suppose it is not improper for this place: Or however, I shall rather venture the danger of impropriety and misplacing, then omit the taking notice of so excellent a Discovery, which no doubt future Ingenuity and Practice will improve to Purposes not yet thought of; and we have very great likelihood of advantages from it in present Prospect. For it is concluded, That the greatest part of our diseases, arise either from the scarcity, or malignant tempers and corruptions of our Blood; in which cases Transfusion is an obvious Remedy; and in the way of this Operation the peccant blood may be drawn out, without the danger of too much enfeebling Nature, which is the grand inconvenience of mere Phlebotomies. So that this Experiment may be of excellent use, when Custom and Acquaintance have hardened men to permit the Practice in Pleurisies, Cancers, Leprosies, Madness, Ulcers, Smallpox, Dotage, and all such like Distempers. And I know not why that of injecting prepared Medicines immediately into the blood, may not be better and more efficacious than the ordinary course of Practice: Since this will prevent all the danger of frustration from the loathe of the Stomach, and the disabling, clogging mixtures and alterations they meet with there, and in the intestines, in which no doubt much of the spirit and virtue is lost. But in the way of immediate injection they are kept entire, all those inconveniences are avoided, and the Operation is like to be more speedy and successful. Both these noble Experiments are the late Inventions of the ROYAL SOCIETY, who have attested the reality of the former, that of Transfusion of Blood by numerous trials on several sorts of brute Animals, Indeed the French made the Experiment first upon humane Bodies, of which we have a good account from Mounsieur Dennis. But it hath been practised also with fair and encouraging success by our Philosophical Society. The other of injection, if it may be mentioned as a different invention, was also the Product of some generous Inventors; though indeed more forward Foreigners have endeavoured to usurp the Credit of both▪ This latter likewise hath succeeded to considerable good effects in some new Trials that have been made of it in Dantzick, as appears in a Letter written from Dr. Fabricius of that City, and Printed in the Philosophical Translations.

A●● 615. discourse about the Transfusion▪ of Blood, but I think all the World will condemn him for ascribing either the invention of Transfusing blood, or of injecting Medicaments into the veins, unto the Society. That the latter was a thing much practised by Dr. Wren and others in Oxford, before the Restoration of his Majesty, and before that ever the SOCIETY was thought upon, is a thing known to all that were at those days in that University. I saw myself in those days the Dog into whose veins there was injected a Solution of Opium, at the Lodgings of the Honourable Robert boil, of which he makes mention in his second discourse of the Usefulness of Natural Philosophy, and Borrichius in his Letters to Bartholinus. As for that other of Transfusing the blood out of one Animal into another, if the Question be who first proposed it into the World to be tried, it is certain that Libavius first did that, at least I know not any more ancient then Herald That Learned man above Fifty years ago, so plainly describes the Transsusion, that one can hardly discourse of it with more clearness, than there is done in these words. Adsit Juvenis robustus, sanus, sanguine spirituoso plenus: Adslet exhaustus viribus, tenuis, macilentus, vix animam trahens. Magister Artis habeat tubulos argenteos inter se congruentes, aperiat arteriam robusti & tubulum inserat, muniatque mox & aegroti arteriam findat▪ & tubulum foemineum infigat: jam duos tubulos sibi mutuo applicet, & ex sano sanguis arterialis calens & spirituosus saliev in aegrotum, unaque vitae fontem afferet, omnemque languorem vellet. This allegation was made use of by an Italian Philosopher, and silenceth all those in England, or France, that pretend Philos. Transact. Numb. 37. p. 740. By his leave it infers only the mention of it to be more ancient, not ●e Operation▪ Libavius proposeth it out of some Paracelsian Magical Writer, and not from his own Fancy: adding that the Physician who practisethths Transfusion, deservs Helleborc himself. See Mr. J. Denny's Letter in the Transact. numb. ●7. 〈◊〉. num. 28. to the Glory of having first proposed: So that the Author of the Philosophical Transactions confesseth it in these words▪. This indeed is clear enough, and obligeth us to aver a greater Antiquity of this operation, then before we were aware of, though 'tis true, Libavius did not propose it, but only to mock at it (which is the common fate of new Inventions in their Cradle) besides that, He contrives it with great danger both to the Recipient and Emittent, by proposing to open Arteries in both, which indeed may be practised upon Brutes, but aught by no means upon Man. Till that learned Italian had instructed the Virtuosos in the point, there had been a great Controversy agitated between the French and English Societies about the Invention. The former pretended, that it was mentioned first amongst them about eleven years ago, at the Assembly, in the house of Mounsieur de Montmor, and that the public is beholding to that Monsieur for this discovery, and the benefits and advantages that shall be reaped thereby. But about the person that should first mention the design, the French vary. Monsieur de Gury fathers it upon the Abbot Bourdelot: but the Author of their Journals upon a Benedictine Friar. Our Society having given the world occasion to take notice of it publicly, and having otherwise long before pursued the Oxford-Invention of injecting Liquors into the veins, thought themselves injured in this, that the French should usurp the Credit of such a discovery as had its first birth in England, upon a pretence that it was conceived in France: it being notorious, the French took occasion to try it by the Example of the English Virtuosos: and there being no public record cited, declaring the time and place of the Invention proposed the Method to practise it▪ and the success of the Execution, Thereupon began a Paper-scuffle betwixt the Gazettiers o. the Curiense which any man may read with some pleasure, because they had on both sides such little Logic, as to argue from the mentioning of a design, to the effecting it. If the way of Argumentation be good and solid, then Aristotle, and such of the Ancients, as proposed the squaring of the Circle, must not be denied the glory of being Inventors of it: So they which first proposed a perpetual motion, or the Northwest Passage, may go for Inventors of them: yet are none of these things yet discovered. Oh! new Correlates, and worthy of our Inventors! Long ago Aristotle and the Common dialectics told us, Datur scibile de quo non datur Scientia. But none like our Anti-Logicians-ever taught, there were a sort of Inventors whose Inventions were yet to seek. All that our Inventors did, was, that after Dr. Lower had first discovered and practised the Transfusion at Oxford in February 1665. They on the seventeenth of May following See Transact. Num. 28. pag. 5●4. 1665. gave order that there should be trials made for transfusing the blood: but their trials proving lame for want of a fit Apparatus, and a well continued Method of Operation: the▪ Dr. sent them a convenient Method for effecting the thing. Before this, there never was any mention or proposal made at the Society concerning the Transfusion, as I am certainly informed by one of their Number, who hath examined their Journal▪ Books, in which such Proposals and Experiments are recorded. Nay, they were so far from pretending to it at first, that when it was mentioned unto them by Mr. boil, there were some as well severe as ingenuous Critics, who thought it somewhat strange and bold for him to affirm that the Dr. had made it succeed. And besides, I observe that Mr. Boil in his Letter to Dr. Lower (who hath vindicated the Invention to himself in his late Book de Cord) doth not say that ever the Society had thought of or attempted, or designed to attempt the thing. He calls it insolitum & insperatum conamen. June 26. 1666. and desires He would acquaint the Society with the manner how he achieved it. Now since that neither was Dr. Lower than of the Society, nor any way entitles them unto it, but himself, and that in a Treatise wherein he doth not so much as call himself a Member of that Assembly, set any In the Transactions numb. 37. pag. 371. The Gazettier affirms, that upon further investigation it was by good proof (which is in his hands) proved▪ that the invention had been known to some Ingenious persons in England thirty years ago. If so, then is not the Society the Inventors of it, except we will say, that Societies as well as individual ●o●'s do pre-exist! But may not a man ask our Gazettier▪ where is the public record of this Invention? what Account is there of the Method with which it was practised? with what success? How comes all this to be concealed till after Dr. Lower achieves it, and the French pre●end to it? would any man have concealed their claim to the Discovery, after that it was become the talk of Europe, the Darling of the Society and worthy to be disputed for by the French? why did they not put in their Claim, being within hearing, till about three years after. man judge with how much truth this other Discovery is ascribed to these NEW EXPERIMENTATORS, by our Virtuoso. But lest I should seem to deal too severely and maliciously with them, rather than it shall be said That they invented nothing, I grant, that They invented a LIE; and shall conclude the Debate by representing the words out of their Transactions, by which they assume to themselves the Credit of the Invention, and by a dubious wording and pointing of the Period, insinuate as if Dr. Lower as well as Dr. King had been encouraged to the Attempt by the Society. Philosoph. Transact. Numb. 27. pag. 490. How long soever that Experiment may have been conceived in other parts (which is needless to contest) it is notorious that it had its Birth first of all in England; some ingenious persons of the Royal Society, having first started it there, several years ago, (as appears by their Journal) and that dextrous Anatomist, Dr. Lower, reduced it into practice, both by contriving a Method for the Operation, and by successfully executing the same, wherein he was soon overtaken by several happy Trials of the skilful hand of Dr. Edmund King, and others encouraged thereunto, by the said Society, which being notified to the World Numb. 6. 19 & 20. of these Transactions printed Novemb. 19 & Decemb. 17. 1666. the Experiment was soon after that time heard of to have been tried in foreign Parts, without hearing any thing of its having been conceived ten years ago. In which relation, I must take notice that it doth not really appear in their Journal-books, that ever any such thing was started by any persons how ingenious soever of their Society; Dr. Lower being not then, nor long after in the History of the Royal Society reckoned as a Member of it. Nextthat the interpunction of the period is so equivocally placed and ponned, that the unwary Reader may think that Dr. Lower, as well as the others was encouraged to the trial by the Society. Whereas he was not, whatever the others were. Again, it is disingeniously said, that he was soon overtaken by several happy Trials of Dr. Edmund King, and others, encouraged thereto by the Society. Since it appears by the letter of Mr. boil, that the Society knew not how to do the thing in June, which Dr. Lower had effected in February, and the fame thereof at that time was spread over England. In July Dr. Lower acquainted the Society with the manner of the Transfusion, whereof Dr. Wallis had given the Society an imperfect account a little before of what he had seen Dr. Lower do at Oxford. So that for at least four or five months, the Members of the Society did not overtake Dr. Lower. But after they were acquainted with the contrivance, they invented it very clearly. From hence it is easy for any man to judge with how much right Mr. Glanvill doth say, that both the injecting of Medicines, and transfusing blood into the veins of Animals, those Noble Experiments were the late Inventions of the SOCIETY. I shall now proceed to inquire into the Utility▪ of them; thereby to discover how noble and excellent they are, and what advantages we may hope to derive from them hereafter. Because this Transfunding of blood hath hitherto been looked on as the primary Invention, and the most famed of any the Society were ever entitled unto: and that they themselves have particularly concerned themselves in asserting it to be their discovery, to the end that every Reader may the better be able to judge of the Controversy, without being forced to go seek out amongst the scattered transactions and elsewhere, several Histories that are material to the passing a right judgement; I shall crave pardon if I do relate particularly the matter of fact, and what hath been sundry times performed by the English, Italian and French Virtuosos, with every circumstance, both as to injecting of Medicines, and of blood into the veins. As to the injecting of Medicaments into the veins, it is an Experiment that I am apt to think was first tried by the English, and as a curiosity, it was not unpleasant; but that it should be so advantageous a discovery as Mr. Glanvill represents it is like to be, I do not believe. There was a time when men had regard to their Consciences, and what could not be administered but upon prudential hopes of advantage to the Patient, no approved Physician durst, or would give to any sick person: but in this Age▪ such as ought to protest against it, are as forward as any to forget these considerations, and prompt men on to practices without either regarding whether the effect be not Murder in the Physicians, besides the ill consequences to the diseased. In the injecting of Medicaments, I must complain that neither the Operation of Medicaments immediately injected into the blood and veins is known, nor the dose; and consequently the Project not like to improve Physic at all, unless our Magistrates will licence men to try so many Experiments, even to the apparent hazard or certain death of the parties, and may regulate and authenticate the practice in such manner as becomes a Baconical Experiment: and to encourage Rational men to this procedure, there ought to be a greater deficiency in Physic, than yet appears, and a more hopeful success than any man can yet expect, supposed by this way. A Paynim told us, Nulla unquam de morte hominis cunctatio longa est. A sober Physician will look upon the act to be as indiscreet, as the Comedian describes love to be▪ Quaeres in se neque consilium, neque modum habet ullum, eam consilio regere non potes. That there is no probability that this way of Medicine can ever amount to any thing, appears from this consideration, that Liquors immediately injected into the blood, have a different Operation there, then when taken in by the Stomach: and that the mixtures of Liquors with blood upon Phlebotomy in a Pottinger, gives no light to the Experiment. As I shall now show. Signior Fracassati Professor of Anatomy at Pisa tried these Experiments by injecting Medicaments. 1. Having injected into the jugular and crural veins of a Transact. num. 2●. p. 490 491. Dog some Aqua fortis diluted, the Animal died presently: and being opened, all the blood in the vessels was coagulated and fixed: but that which was in the Viscera (which I dare not English Guts, but take it to denote the Heart, Liver, C●r. Fracassar. Ep, Anat. de cerebro. p. 252▪ 253▪ ●54. Lungs, Spleen, where the blood passes extravasated through: though the Transactions render it Guts, and destroy the antithesis betwixt vasa and viscera) did not so easily coagulate. It was also observed that the great vessels were burst, or as it were cut asunder, yet have I known who hath put Aqua fortis into cooling▪ Juleps in Fevers, as others do spirit of Vitriol without any harm. 2. There was also infused into another Dog, some spirit of Vitriol, which had not so present an effect: for the Animal complained a great while, and foamed like epileptics, and had its respiration very thick: and observing the beating of his breast, one might easily judge, the Dog suffered much: who dying at last, his blood was found fixed in the veins, and grumous, resembling Soot: whereas in the Experiment with Aqua fortis (which may as easily be given inwardly as spirit of Nitre) the blood is not said to have been changed in its colour from other coagulated blood. It was also observable (though the Transactions mind it not) that the blood in this last Dog was not upon coagulation continuous in the veins, but broken and severed into parcels. 3. There was also injected into the jugular of another dog, some oil of Sulphur per campanam, but he died not of it, though this infusion was several times tried on him. And the wound being closed, and the dog let go, he went into all the corners of the room, searching for meat, and having found some bones, he fell to gnawing them with a strange avidity, as if this Liquor had caused in him a great appetite. 4. Another dog, into whose veins some Oil of Tartar per deliquium was injected, did not escape so well: for he complained much, and was altogether swollen; and then died: Being opened, the Spectators were surprised to find his blood not curdled, but on the contrary more thin and florid then ordinary. 5. Dr. Lower having extracted half a pound of blood out Dr. Lower de motu Cordis pag. 1. 9 of the crural urine of a Mastiff dog, did inject the like quantity of warm milk into him; within half an hour the dog became very sick, breathed with difficulty, and seemed to labour much with his heart and diaphragme, and after to palpitate, tremble and sigh grievously, and at length miserably died. Upon dissection he found the vena cava, the ventricles of the heart, the vessels of the Lungs, and the Aorta full of blood and milk coagulated together, and the concretion was so Transact. num. 27. pag. 49●. hard, that it was not easy to part it. This he tried but once. But Monsieur Dennys the French Physician saith, he tried it with a different success. For having syringed about a quarter of a pint of milk into the veins of an Animal (he tells not what) and having opened the same some time after, he found the milk so perfectly mixed with the blood, that there was not any place in which appeared the least footstep of tho whiteness of the milk, and all the blood was generally more liquid, and less apt to coagulate. 6. I received an account of some Experiments, from one much versed in these injections (which he may one day acquaint the world with) to this effect. That the infusion of Crocus Metallorum, injected in a less quantity than otherwise (viz., ℥ β) will work by vomit in a dog▪ almost presently, and very strangely, and make him grievously sick. Yet Dr. Mr. Boil of the Usefulness of Nat. Philos. part. 2. p. 54, 55. Wren informs Mr. boil, that a moderate dose of the infusion of Crocus Metallorum did not much move the dog that he injected it into: but a large dose of two ounces or more wrought soon, and so violently, that he vomited up life and all. That a dog will take two drams of Opium into his Stomach, and seem never the worse, if you keep him from lying down half an hour after; but two drams of Poppy-seeds made into an Emulsion, and injected into his veins, will kill him presently. 7. Mr. boil saith, that he conveyed a small dose of the Vid. supra p. 53, 54 tincture of Opium into a dog this way, which began to work so speedily upon the brain, that he was scarce untied before the Opium began to disclose its Narcotick quality; and almost as soon as he was upon his feet, he began to nod with his head, and reel and falter in his place; but being kept awake, and in motion, by whipping up and down the Garden, after some time he came to himself again, and not only recovered but began to grow fat so manifestly, that'twas admired. 8. A certain Germane Count coming into England, relates Phil. Jac. Sachs in Ocean▪ macromicrocosm. sect 155. an Experiment, which he saw in the presence of Pr. Rupert. After some blood taken from a dog, there was injected into him a small quantity (portiuncula) of Spanish wine; within sometime after the dog was perfectly drunk, being giddy, performing sundry ridiculous actions, then vomiting with a profound sleep. 9 Dr. Fabricius Physician to the City of Dantzick injected Transact. numb. 30. pag. 564, 565. purgatives into humane bodies, with this effect. A strong bodied Soldier being dangerously infected with the Pox, and having grievous protuberations of the bones in his arms, two drams of a purgative liquor were injected: he presently complained of great pains in his elbows, and the little valves of his arm did swell so visibly, that it was necessary by a great compression on's fingers to struck up that swelling towards the Patient's shoulders. Some four hours after it began to work, not very troublesomely; and so it did the next day, in so much that the man had five good stools with it. Without any other remedies those protuberances were gone, nor are there any footsteps of the disease left. Two other trials were made upon women, the one a married woman of 35, the other a Servant-maid of 20 years old: both from the birth had been grievously troubled with Epileptic Fits, so that there was little hopes of curing them. There was injected into their veins a laxative rosin, dissolved in an Antiepileptical spirit; the first of these had gentle stools, some hours after the injection; and the next day the Fits recurred now and then, but much milder; and are since quite vanished. The Maid, she went the same day to stool four times, and several times the next: but by going into the Air, and taking cold, and not observing any diet, cast herself away. 'Tis remarkable, that it was common to all three, to vomit soon after the injection, and that extremely, and frequently. I have not time to add any more of these kind of trials: but from hence it is evident, that things operate (where they do operate in the same manner) in a lesser dose, than when taken into the Stomach, and with Vulgo hactenus a non ●●ucis sp●●itus Vitrioli, & Sulphuris pro diversis r●b●s habiti sunt: adeo quidem ut nonnulli flores sulphuris & acidum ad c●sdem pulmonis merb●s exhiberent: sed valde imp●●ite cum ac●●a omnj● sin● pectori inimica, & spiritus Sulphuris & Vitri ●i ess●ntia null● modo differant▪ sed ex cadem re generent●r, & parentu●.

Senne●t. in Paralipomen. ad institut. l. 5 part. 3 sect. 3 c. 5. more violence. That oftentimes such things as are innocently taken into the Stomach, are mortal when injected immediately into the blood. That although learned Physicians have made little or no difference betwixt the operation of Oil of Sulphur, and that of Vitriol, yet by this Experiment there is found to be a quite different effect. So the Salt of Tartar (which is as innocent as Salt of Wormwood, or any such Salt) had a pernicious effect upon the dog, though discrepant from the others. As to the Experiments of Dr. Fabritius, they do not give much of Encouragement to the Trial, for the one died which had the most of youth; and though her death be attributed to other circumstances and neglect;, yet either those are trivial, or for some (unknown) length of time there must be greater care then ordinarily after Physic, otherwise small accidents become mortal. And the extreme and frequent vomitings (which here happen from the sufferings of the Heart, and not the Stomach) render the course more hazardous to tender Stomaches, and weak Constitutions, than Mr. Glanvill suggests. So that the loathe of the Stomach are not prevented by this way, nor the success very inviting (how speedy soever) upon those Experiments any more than from the Churlish Physiek of the ancient and moderate Chemists of Mr. Odored's party, which wisemen will not imitate. I wonder the laxative Solutions were not set down that we might judge of their strength: and that the way of dieting and ordering of them afterwards was omitted: whereas the knowledge thereof might avail to prevent the ill consequence which befell the Maid. I shall now consider the effects which the several Liquors have upon a mixture with the blood, when taken warm in a Pottinger, and those affused to it. This is a Practice which the Honourable Mr. Robert Boil imparted to the Royal Society in December 1664. and thinks that Fracassati may have taken his hint from it, to inject those Liquors: but I find a Letter from Leyden sent to Bartholinus, Dated Jan. 9 1662. in which there are several Experiments of that kind, which I shall set down presently. If I placed any great value upon the Experiment, I could put in for the Practiser of it at Stratford upon Avon in 1660. and prove that I made some Solutions of Salt of Ash, Salt of Wormwood, and Salt of Tartar, and received the blood of sheep into the glasses in which they were, to try the differences betwixt those Salts, whether they were of the same nature (so that it was indifferent whether one used Salt of Wormwood, Carduus Benedictus, Yarrow, or Mugwort) or that there were any difference. Which last Angela Sala denies, though other Angelus Sal● Tartaralog. sect. 3 c 2. p. 133. Chemists affirm it. But after that I had enquired into that Controversy by several ways, I went to Jamaica and neglected the Experiment. But since that I see that every unprofitable trifle, becomes a famous and noble Experiment, and if it bring no present Emolument, yet at least it becomes Luciferous, and (as they say) puts us in the Prospect of several great advantages; at least, more and greater things will be disclosed by it, when future ingenuity and diligence hath improved and perfected the invention. Since that time I have made many Essays about the mixture of sundry Liquors, with the blood of Sheep, Lambs, Calves, Cows, Oxen, Hogs, Poultry, and that in several manners. I have received the blood of several creatures upon warm solutions of sundry Salts, of Allom, impure Saltpetre, Sal Prunellae, Salt of Nitre, upon solution of the several Vitriols; upon Steel-wine, Vomitive wine, Sack, French wine, and Malaga, upon spirit of wine, spirit of Cider, and spirit of the grounds of Beer; upon warm Urine, upon mixtures with spirit of Vitriol, and oil of Sulphur, and Juice of Lemons, and Oranges, upon the rare liquor os Saltpetre; upon it, after it hath passed the Ashes, and upon the Mothers of it, and many other trials with oil of Wormwood, Amber, etc. dissolved in spirit of wine. I have also poured upon the Mass, after it hath coagulated several acid spirits, before and after the Serum was separated from it. I have also taken the separated Serum, and affused spirit of Vitriol to some; to others spirits of Hartshorn, and other spirituous waters, and I have affused to those that had a mixture of the spirit of Hartshorn some acid spirits, and other liquors to see the changes. I shall not now set down the several Phaenomena, and observations I made, not having leisure to digest them all, nor being willing to dismember a discourse I intent about the nature of blood and Phlebotomy, in which I shall not only treat of all these things, but add many other observations, from the burning of blood, and the Serum, which any man may do, without feeling any thing by sympathy, notwithstanding the whimsies of Helmont, and that great Virtuoso Sir Kenelm Digby. I have done it forty times in Men, Women, and Children, to observe those varieties in blood, which never entered into the heads of our Experimentators Though Dr. Walter Needham, my learned School-fellow, a Member of the Society, deny that blood will burn, Carbonibus injectus Disqui●it, de soetu. pag. 130. sanguis flammam non facile concipit, sed potius torretur in grumum. Yet if any one please but to take a piece of the coagulated Mass of blood, and lay it on a Fire shovel, and so place it in an hot fire, that the coals arch round about it, but touch it not: after he hath observed the great variety of its intumescence, and the crackling of divers salts, as it were decrepitating, it will take flame commonly when dry, and burn with a great variety of Phaenomena: some will not flame at all, though brought to ignition: there will be also variety in the remaining Cinis, as to its saltness. In the like manner set the Serum to coagulate on the coals, and then burn it. I have also burned the blood and Serum, after it hath been mixed with acid liquors. By this trial will appear more than can be imagined as to the differences of the blood of Animals, and of young and old Animals, I will endeavour to finish that Tractate, wherein there will be observations about the colour of blood, and melancholic, and pituitous, and crimson parts; and a certain pellicle which generates by the Air on the top of most blood, if it stand 24 hours; which sometimes is as firm as those tunicles that encompass the Liver, or Kidneys. Observations upon that, and upon the turning of the coagulated Mass, and its becoming red again, though not so floridly. Trials upon that in vessels covered, that it is not from the air, in opposition to the Fracassati. I will not mention any thing hereof now, but having imparted some observations to some, and knowing what plagiaries some men are, I thought fitting to publish thus much, that they might not pretend to the inventions, each whereof were enough to make one of them proud, and fill the Transactions. Yet I will say this, That I never had put myself upon these trials, but out of envy and indignation against them, and the Transfusion of blood, about which they made such ado every where. I shall promise one thing, that Mr. boil is very much mistaken in, imagining that there is a great difference betwixt the effects of Medicaments, when mixed with the warm blood of an Animal out of the veins and in them, as will appear by the mixture of milk already specified, and that of the Salt of Tartar, which will follow out of the Letter of Borrichius. Experiments upon the mixture of Liquors, with the warm blood of Animals, taken out by Phlebotomy. 1. By putting into the warm blood, as it came from Animals, Transact. numb. 29. p. 552. a little Aqua fortis, or Oil of Vitriol, or spirit of Salt, (these being the most usual and acid menstruums) Mr. Boil observed, that the blood not only would presently lose its pure colour, and become of a dirty one, but in a trice also be coagulated; whereas some, if fine urinous spirit, such as the spirit of Sal Armoniac, were mingled with the warm blood, it would not only not curdle it, or embase its colour, but make it look rather more florid than before, and both keep it fluid, and preserve it from putrefaction for a long time. 2. The Learned and Inquisitive Man Olaus Borrichius, having Tho. Bartholin. cp. Centur. 3 cp. 97. pag. 421, 4●2 cut up a dog alive, made these observations. He took five glasses, and placed them in order, putting into the one spirit of vinegar, into another oil of Tartar per deliquium, into a third a Solution of Allom, into a fourth spirit of Salt Armoniac, into a fifth spirit of wine; into each of the Glasses, he suffered the blood of the Crural Artery to run. After some time he come to look upon his Glasses, but the next day the observation was most perspicuous. That Glass which had the spirit of vinegar in it, it Insp●ximus post intervallum & plenius postridie omnia: Observavimus sanguinem, ●ui affusus erat spiritus aceti, redditum nigricantem instar sanguinis Melancholicorum, sedimento crasso, copioso, atro, supernatantem liquorem, paene etiam atrum.

Where the Oil of Tartar was, the colour was pretty florid, but the liquor more turbid, no sediment at all, only some filements, like little fibres floated in it conspicuously, here and there. Where the Solution of Allom was, there all seemed like a subcineritious or dirty-coloured putrilage, there being no relics of the crimson colour of blood to be seen. Where the spirit of wine was, there the liquor was more turbid then that which had the Oil of Tartar in it. Where the spirit of salt Armoniac was, that was of the most beautiful colour of all, being very florid, of a thin consistence, with a diaphanous sediment like to the jelly of currants. This observation he also tells Bartholinus, that he had in like manner made the preceding Summer. Out of all which it most evidently appears how nice a thing the blood is, and how small mixtures alter the colour and texture of it: and what consequences may follow upon such alteration of its consistence, and particular texture, no man knows; but that they may be very bad (even where innocent, and wholesome Medicaments are affused) is evident out of what I have set down. It is also as manifest, that there are in the bodies of men and women solutions or liquors imbued with sundry salts, as aluminous, acid, and vitriolate, etc. which when they shall mix with the injected blood, what the issue may be, I leave the Prudent to conjecture. Certain it is, that for these considerations specified (reserving my own Experiments to myself) none but inconsiderate Quacksalvers would put a Patient upon the trial of injecting of Medicaments, or transfusing of blood. It is a course Nature (whose Servants and Imitators Physicians hitherto were) never prompted us unto: Having taken so many courses whereby blood might at any time of need issue out of the veins and arteries in sundry parts of the body: But especially provided that nothing might immediately come into the veins. Whatever comes into the veins by the Stomach, suffers a great alteration first, and whatsoever is noxious, either separates from it there and in the guts, or is mortified, or mitigated so as to be innocent, and agreeable to the nature of the veins. Which particular nature of the sanguiferous vessels, is that which in the dead keeps its own blood fluid, and in the living contributes so Vide ep. Walaei de motu sangu. much to the motion of it, that if you make a stop and intercept the impulse of the subsequent blood, yet will the other continue its course. But what will the effect be of Heterogeneous blood? For undoubtedly the nature of the veins is agreeable to the blood, and communicates its impurities and virtue, as the cask doth to the wine. But further, since the blood is to pass through the porosities of the Liver and Lungs, and capillary veins and arteries, how will they agree with the new blood. (it being evident upon mixture of Liquors, and upon burning, that there is a difference in the fibrosity of the bloods, and consistence of the several Serums) or how will that circulate which results from the mixture, I know not, but certain it is, that the ill consequence is almost, if not absolutely past remedy. In fine, what is it that is aimed at in this Transfusion? is it the rectifying the mass of blood (suppose seventeen pound in a body) with the affusion of a few ounces, or a pound of Lamb's blood? They may as soon rectify as much vinegar, or decayed wine, with the like proportion of good wine? would they amend the impurities of the vessels? there is the same difficulty as before. That which they transfuse is not a Chemical spirit, but an impure, and heterogeneous mixture, fitted by different digestions and ferments to a different nourishment of another Animal, with different excrements resulting from it. It is in the Stomach and first digestion where food is so concocted by the Humane heat, or Acidity, as to turn to a chyle adequate to the nourishment of man, and generating such blood, and such excrements, as are the result of such a concoction as is agreeable to the nature of man. And so it is in all creatures: Thus we see, that in different Animals different Excrements are generated, nor is it to be doubted but that the concoctive principle differs as much in a dog, or cat, as do those excrements which differ much from those of men, though both Otto Tachenius Hippocr. med. clavis c. 9 p. 201. eat the same meat. Sicut acidus spiritus quilibet animam inseparabiliter in ventre suo portat, atque in illud corpus, cu●infunditur, dominium suscipit, illudque confestim juxta sui naturam format: hinc spiritus salis in Alcali Tartari fusus statim sibi format corpus salinum propriae naturae consentaneum, & fit sal: & aceti spiritus, vel acetum distillatum in eodem Alcali tartari sibi format corpus adaequatum suae propriae naturae, & fit tartarus vini, & sic de vitriolo, & reliquis acidis: Ita quoque acidum Stomachi humani, cum apprehendit panem, vel quicquam alibile, in quod dominari possit, illud convertit & commutat in chylum, & exinde in carnem humanam: & eundem panem Acidum Stomachi canini convertit & transmutat in carnem caninam: uti & de reliquis viventibus quotidie docemur, eo quod natura in omnibus iisdem instrumentis operatur. If the Case be such, and that the blood transfused hath received those impregnations of vitality which are agreeable to the nature of the Animal whence it is transfused, and is qualified to generate such nourishment, and such excrements as are the consequences of those digestive characters (if I may so call them) and impressions; How can we imagine that such blood being immediately transfused into our veins, without those previous alimental sigillations and digestions, produce those effects which are to be expected in humane bodies, and are (though irrationally) in this case wished for. But perhaps they think to achieve their design, by introducing a new texture in the vitiated blood, and vessels, or fermentation, whereupon should ensue the amendment. I I had an intention to have set down at large all the Stories relating to the Transfusion of blood, with remarks upon them: but I was so much pressed to conclude, and had so little leisure to dispatch it in that manner at that time, that the Reader must be content with this brief, but I think substantial ●eply to all that hath yet been said. perceive indeed by their stories a new fermentation, that the dogs piss blood (no desirable or trivial accident!) But what a little time is there for the blood to pass unto the heart, and mix with those other Liquors, and ascending blood, and so to pass into the Heart and Lungs? How do they know that the blood they transfuse is good? Upon burning they shall find a difference in blood of beasts; and a different taste and coagulation in the Serum. Besides, that the blood of young Animals is generally less balsamical and inflammable, of another texture and colour, the Serum very saline; and in a word, exceeding different from what is in men and women of years. And in the blood of men and women, there are often defects not to be perceived but by coagulating and burning of the Serum and blood. I have taken the Serum of a Maid seemingly healthful, only pained at Stomach, and abounding in blood, it coagulated and looked like tallow, and would not burn at all, and smelled noisomely after coagulation, not before. I have several strange instances of this kind. If there be such indiscernible causes of distempers, and mixtures in blood of persons that are not well, if they neither know what they aim at in transfusing in, nor what they transfuse, Let Mr. Glanvill talk of great Advantages to be expected, and let them try it for me. Sure I am that the Transactions report See the Stories in the Philosophical Transactions. an Untruth, in saying that Coga was ever the better for it: I am told his Arm was strangely ill after it, and difficultly cured: and if all the great likelihood of Advantages from Transfusion that are in their present Prospect, arise from no other grounds, they are very improbable. The Parliament of Paris have forbid it to be prosecuted but by the allowance of the Parisian Faculty of Physicians. A Swedish Baron died upon it: and to argue from the cures of Madmen, or I remember they say that it is not expressed, how the Transfusion was practised upon the Baron Bond, nor after how long time it was repeated, when he died But this is no excuse for them; for they have fixed no r●les or circumstances whereby to regulate the operation▪ those are to be learned by frequent Experiments, and▪ It may be, th● death of more Patients. Next, it is not to be doubted, but that He that did it might act as cautiously as they, for his own credit, and the credit ●f the trial, and the quality of the Person. It concerns them to procure an Authentic Narration of the th●ng▪ and what appeared upon his being emboweled from what they suffer without hurt, is not for a Physician, but for one that deserves to be sent to Bedlam: for mad people endures a thousand ills, and strong Physic, such as others cannot endure: and if they find any amendment sometimes by uncouth means, it is by accident, as it makes them ill, which sometimes prove their recovery. As for dogs, they cannot declare what they suffer: but I am in haste, and refer my Reader to the perusal of the Histories in the Transactions: in which what I last objected, is all confessed: and if after all I have said, he find encouragement to try a remedy, that hath sometimes proved not unfortunate, (but is always rash) let him do it for me. I am satisfied, That the operation carries more of terror (and many swoon upon bleeding) then a potion, or Galenical Physic; and that the greatest part of our distempers do not arise from the scarcity, or malignant tempers, and corruption of our blood, is as manifest as can be; more arise from the depraved motion, and redundancy of the blood, and serosities in and about the brain, and the laxity and strictness of the habit and pores of the body; and in these cases Transfusion is no remedy; much less in malignant diseases, in which to let blood is often mortal, commonly dangerous; and it always must be antecedent to Transfusion, excepting only the scarcity of blood; in which case what strength is there to assimilate, or ferment with the new blood. As to the Transfusion of blood in Pleurisies, the attempt is very ridiculous, considering what an Ebullition and Inflammation of the blood there is then in the Lungs, whither the transfused blood immediately flows: what extravasated serosities do afflict those parts? how unfit are they for any seasonable fermentation? And in the Small Pox, how few are they in England which allow of Phlebotomy in that disease at all? and how irrational must that Transfusion seem, which disturbs and diverts nature in her present work? what hazard must the Patient run amidst a Fever, and that violent commotion of humours which afflicts his head, back, heart and lungs at that time, should he besides all other accidents fall into pissing of blood, a symptom so dangerous in that disease, and so usual a consequent of this Operation. Having dispatched these papers thus far: the length of time since they were sent to London to be transcribed, perused, and several insertions made, according as my memory, amidst a constant employment, suggested any thing new unto me, and the delay of the Printing till Michaelmass-Tearm, gives me an opportunity to relate some Observations I made at Bath, during my stay there this Summer: As famous as the Baths are, and of as general an use as they are (there being no better Remedy in the world for the Scurvy them the Cross-Bath regularly pursued, and as it might be, I cannot say is commonly practised) yet have not our Experimental Philosophers made any Inquiries into its nature and qualities: not a man of them ever so much as tried the mixing of several liquors and spirits with the water: as I did, and found no change upon the mixture of Acid spirits: but the urinous and volatile spirits of Sal Armoniac (drawn the Leiden-way) and Hartshorn did change the water of the Pump in the Cross-Bath (which ariseth from the hot Bath) into a lacteous colour and opacity, insomuch that it represented an Almond-milk, and after a time there precipitated to the bottom an insipid Magistery resembling Burnt Hartshorn finely powdered: the precipitated powder was more copious in the affusion of the spirit of Sal Armoniac, then that of spirit of Hartshorn: and the former in that mixture lost its urinous smell, (and made no unpleasant, but an unctuous, soft, emulsion-like drink) which the other retained. Not a man of them ever tried whether the several Bathwater would coagulate milk: which I tried first, and found that the Kings-Bath-water makes Posset with a soft curd, and whitish posset-drink, which will not become clear: the Cross-Bath makes an hard eurd, a clean but whitish-posset-drink: the Pump-water of the Cross-Bath (which ariseth from the neighbouring hot Bath) yields an hard curd, a clear and very green posset-drink; which being drunk by a woman that gave suck bred a great deal of milk (more than fennel posset-drink) and made her break abundance of wind, which those usually do that drink the Bath-waters. And I believe this way of giving the Bath-waters might be no small improvement of Physic, were those courses taken there, and that method which those that understnad the ancient and modern Baths, and waters that are drunk, might easily pitch upon: but this is above the reading of our Comical Wits. I could find no grounds to believe there was any sulphur, or bitumen in the Baths: but rather Mr. Changed Hotham, when I showed him some of the extracted Salt, did conceive it to be a mixture of common Salt, and vitriol of Iron. When I was there, a Spring of the Cross-Bath being lost, they digged for it▪ I tasted the Earth, but could find nothing nitrous in it: opening the gutter by which that Bath empties itself, we found the passage crusted very thick, with a white lapideous concretion, rough and unequal in the surface, with several crystals fixed in it, resembling those of cream of Tartar: to taste, it was insipid, an● of substance like to what precipitates with urinous spirits in the water: but after it had ●en on the tongue a while, some p●eces discovered a taste exactly like cream of Tartar, others an adstriction somewhat vitrioline. I brought some away, and intent to examine it further. some odd Alcali mixed with the vitriol of Iron: I extracted the Salts by evaporation of two gallons of the Cross-Bath-water; and having reduced them to three quarts I set it to shoot; but there was no appearance of salt-peter at all: then I evaporated it to three-pints, but still neither salt-peter, or any other salt appeared: then I evaporated it quite away; and then I had about two ounces of a dark▪ coloured salt, which at first resembled cream of Tartar somewhat in taste; but having lain longer on the tongue, it resembled very much the Vitriolum Mortis, with some more Alcalisate taste: I performed the Operation both in Iron and Glass vessels with little difference of the taste, or quantity of salt: some of the said salt dissolving into a moisture in the air did eat off the writing upon such papers as it fell, and turned the paper yellow all over, and rotten it. I made a Lixivium with the Cross-Bath water, and evaporated that, thinking that if there were any unctuous matter in the water, it might hinder the discovery of the Nitre in its shooting; but neither could▪ I find any thing of Nitre this way: but still there was a taste of the Vitriolum Mortis in the salt: and one Mr. Berenclaw a Practitioner there assured me, that he had known the Bathwater drunk, and to have tinged the Excrements black, but I cannot avow the truth of that. I inquired about the truth of what Dr. Mearn had writ about the Stone he took up, upon Landsdown, which being infused in water produced a resembling heat and taste to what is in the Bath: But Dr. Maplet, an inquisitive and learned Physician there, who was with Dr. Mearn then, and had some of the mineral stone, assured me it was a limestone: so did Mr. Chapman an observing Apothecary there, who likewise saw the Stone, and tasted the infusion. In fine, where Dr. Me●ra took up that Stone, any man may take up a thousand, they not being cast out of the Earth, but dropped out of the lime-carts which pass that way into bath, the Kills being thereabouts. The stones in the bottom of the Cross-Bath, many are of reddish rusty colour, others green: but concerning the bath, I may next Summer, during my stay there, in the midst of June and July (if God give me life and health) make a further Narrative: I only mention this to prevent the Virtuosos from usurping upon my discoveries and intendments. Yet to do them some justice, I was told that in some of their Transactions,▪ they have this observation about bath, that if any person that is drunk go in there, the Bath will make him sober: If any that is in the Bath drink freely there, it will cause him to be presently drunk, with less drink by far then if he were cut of it. This report is worthy of our Philosophers, and advanceth their intelligence above the credit that Aristotle and his Hunters deserve. The first part is defective, for it should have been added that the drunk person must sit still, and sweat sound: if he stir up and down or swim, he shall be more sick than if he had never come in. The second part is notoriously f●lse, and all the Bath-Guides and others that have tried it▪ avow, that 'tis usual for the Townsmen to sit some hours and drink in the Parlour of the Queens-Bath, and never be drunk: and they say, a man that sweats there shall bear much more drink, then if he were out of the Bath: which I thought rational and agreeable to what I had observed in the Indies, where men sweat and have more drink than in England, and stronger. But I come now to that Case, for which I add this Discourse, and that is, Observations upon the mixture of the Bathwater and other Liquors with blood, and the Phaenomena thereupon, which, though I might reserve for that other discourse of mine about Phlebotomy, yet I will oblige my Reader with some of those Curiosities here, especially since it will give him occasion to reflect how facile it is to multiply such Experiments, and how negligent they are who pretend to be the grand Observators of this Age. When I went to make use of the Bath, amongst other Preparatives thereto (which are better taken upon the place, then at a distance) I caused myself to be let blood, and being willing to improve that occasion as well for my instruction, as health, I caused several Venice-Glasses to be filled with several liquors, each liquor amounting to some three ounces, and into each glass I suffered to run as much as half an ounce of blood, or little more; taking no other measure, then that the whole liquor seemed of a deep blood red. The Phaenomena thereupon were these ensuing, being observed presently after I had bound up my arm, and was in condition to write. 1. That Glass which contained the spirit of Sal Armoniac (drawn the Leiden-way) kept of an equal consistence from top to bottom, being of a deep red, and not transparent, like Tent-wine. 2. Into two several Glasses I had dissolved the Salts of Ash and Wormwood, half a dram in three ounces of water; the solutions of these two Salts showed no difference at all; the top, after some space, was of a florid red, (such as is visible in waterish blood) for about a quarter of an inch: the bottom was of a more dark red, and resembled Tent-wine. 3. A foutth Glass held Oleum Tartari per deliquium: the blood and that liquor did not first mix, but were as two distinct liquors, notwithstanding that the blood had streamed into the Glass: After a while the blood and oil mixed together, and it all became of a deep red from top to bottom; the surface only was transparent, and of a brighter red, as that of the other Alcalisate Liquors, but not so far downwards: the rest was as Tent-wine. 4. I dissolved half a dram of Allom in three ounces of water, and upon bleeding thereupon, all the crimson of the blood was immediately destroyed, and it became almost as black as Ink: after a little space towards the surface it cleared up: there were certain bubbles on the top that continued the redness. 5. Another Glass held a quantity of the Kings-Bath water, the blood that did stream into it, appeared of a dark red, but transparent, as deep Bourdeaux wine shows: a little below the surface it was deeply red, not transparent, but like Tent wine. 6. The Cross-Bath altered little from the Kings-Bath, saving that the transparency of the surface extended itself downwards to a greater profundity than the other. 7. A Solution of half a dram of Sal prunellae, yielded a blood on the surface like to that of Salt of Wormwood, but not to so deep a descent: otherwise it was of the colour and consistence of Tent wine. After they had stood in the window about five hours, I returned and observed these Phaenomena. 1. That with the spirit of Sal Armoniac continued like Tent-wine, only the uppermost part of it to the thickness of a barley-corn, was diaphanous as deep Bourdeaux-wine. 2. That with the Sal prunellae coagulated into a Mass, shrunk from the sides of the Glass, and sunk to the bottom, leaving them super-natant water of a pale citrine colour; the Mass itself being of a florid red on the surface, and of a deep red, not blackish, to the bottom, that I could perceive. 3. That with the Cross-Bath water changed not, but seemed thick as Tent-wine, the upper part being diaphanous, and like deep Bourdeaux-wine? 4. That with the Kings-Bath water changed not; only the diaphanous surface extended not itself downwards so far as the other Bathwater did. 5. The Solution of Allom continued all fluid and black; no coagulated mass therein: but the bubbles had lost their crimson-colour, and were become cineritious▪ 6. That with the Salt of Wormwood resembled deep Bourdeaux wine, but was less diaphanous a little below the surface: The surface extended downwards to the length of a barley corn with a perfect transparency. 7. That wherein was the Sal fraxini was diaphanous to the bottom; no innatant filaments or coagulated mass in it: But the surface to the length of a barley-corn was like decayed Claret made with a mixture of white and red wine: the residue was deeper like that of Bourdeaux. 8. That with the oleum Tartari per deliquium was diaphanous to the length of a barley-corn, and of the colour of Bourdeaux wine: the lower part un-coagulated, and like Tent wine. 9 It is to be noted, that the reflection of the Glasses in all the Liquors, they being held up to the light, (except the spirit of Sal Armoniac) did create a corona of several colours, mixed with green, blue, and so as not one resembled the other. That with the oleum Tartari per deliquium resembled the blue in Bourdeaux wine, with an eye of green. I had forgot to relate how I kept some of the blood in a separate Pottinger; and it seemed excellently well coloured; when it coagulated, the top was of a due red, the bottom blackish red; the serum of a due transparency and proportion, and not tinged to citrine colour: and coagulated all as the white of an egg over a gentle fire. I poured also upon the blood in two other Pottingers; upon the one spirit of Hartshorn; on the other spirit of Sal Armoniac, but not much: perhaps a dram or more: that with the spirit of Hartshorn at first seemed more florid, then that with the spirit of Sal Armoniac: both coagulated into Masses after a while, and were then both of one colour on the surface: but that with the spirit of Sal Armoniac coagulated its Mass so as to break from the sides: that with the spirit of Hartshorn did not break from the sides; whether the blood of one, and the other might differ, I know not; but both immediately followed one the other. That blood which had nothing mixed with it, after coagulation, differed not from the other two, though they were covered over with the spirits as soon as they were taken, and that exposed only to the Air. After a while upon the surface of that with the Kings-Bath-water, there was a kind of fatty cremor which covered the whole surface; and so on that with the Queens-Bath-water: the others had none at all. On Monday after dinner, the next day after I had bled, I came to observe again; and found, 1. That with the Sal fraxini to be more and more diaphanous, resembling Bourdeaux wine: that with the Sal abscynthii less diaphanous, but red still. 2. I observed the Solution of Allom, and however it looked black, yet being held in a clear light, one might discover in it visible appearances of a deep red. I poured on it some spirit of Sal Armoniac, to see if it would restore the colour: but in stead of that the liquor coagulated presently into little massulae or flakes, resembling raw flesh when the blood is washed out. 3. There was no alteration in that with the spirit of Sal Armoniac. 4. That with the Queens-Bath-water continued more diaphanously red towards the top: but that with the Kings-Bath water, did not lose its redness, though it were not diaphanous near the surface. 5. Of the two Pottingers in which were the spirits of Heart's horn, and Sal Armoniac, though both were coagulated, yet that with the spirit of Sal Armoniac was the most florid. 6. That with the Oleum Tartari▪ per deliquium continued red, but lost its diaphaneity at the top almost quite. 7. That with the Sal prunellae after the coagulated Mass had subsided, had on the top of it in the middle of the Glass, to the breadth of sixpence, a concrete jelly, exactly resembling that of the clearest Hartshorn, not boiled up to its greatest height; from hence protended certain filaments, with which it was fastened to the mass of blood, which was buoyed up thereby, so that it touched not the bottom; the jelly was insipid and stuck to my finger, when I touched it: whether that little which did so adhere took off from the equipollency of the two bodies; or whether I broke casually some of the protended filaments, or from what other cause I know not; but after a while the Mass sunk quite to the bottom, and drew the gelatine below the surface of the water. 8. Upon the pouring out of the blood, that with the Queens-Bath water happened to seem of a pure Claret, like Bourdeaux wine, no settling, or floating filaments, but something red, which resembled exactly the flying Lee in bo●led Claret. 9 That of the Kings-Bath-water appeared as the former, only at the latter end, as it was poured out, there was a certain gelutine mixed with it, and sticking to the sides, that for colour and consistence exactly resembled the jelly of red currants. 10. That with the spirit of Sal Armoniac upon effusion, appeared like deep Bourdeaux wine, and so from top to bottom without any alteration. 11. Upon the effusion of that with the salt of Wormwood, it appeared also like to Bourdeaux wine; but towards the bottom there was Gelatine red, like that of red currants, more tenacious and in greater quantity than was in that mixture with the Kings-Bath-water. 12. That with the sal fraxini poured out like common or less deep Claret: at the bottom there was no Gelatine, but it ran a little thicker like to Tent wine. 13. That with the Oleum Tartari per deliquium, upon its first effusion ran like Claret a little decayed: but the most of it dropped, as if it were a weak Gelatine, and so continued to the last, being almost of as deep colour as a ripe Mulberry; I poured upon some of the said jelly almost as much of the spirit of Sal Armoniac, and it immediately dissolved all the jelly, and made it fluid, yet so as that the bloody crassament appeared unequally mixed, some parts being more deep and opacous than others. 14. I took the Pottinger in which was the blood with the spirit of Hartshorn affused to it, having separated the mass from the sides of it, I poured out the Serum, which was as black as common Ink: the surface was red, but not so florid as that with the affused spirit of Sal Armoniac: most of the melancholy blood seemed dissolved into that black Serum, the super-incumbent mass being thin. 15. That blood on which the spirit of Sal Armoniac was poured in the Pottinger, appeared from top to bottom red, only in the bottom there were some little spots of a blackish and darker red than the other parts: on the surface there was a Gelatinous pellicle generated: the Serum was of a citrine colour: the consistence of the coagulated mass of blood here was more tenacious and fibrous then in that other Pottinger with the affused spirit of Hartshorn: There was no pellicle discoverable upon that with the spirit of Hartshorn; upon that with the spirit of Sal Armoniac so tough an one, that it would bear up a little way in your hand the whole mass of blood adhering to it. 16. The blood which was kept in a Pottinger without any mixture, being placed in an arched fire on a fireshovel burned with a bright and continued flame, as if it had been Turpentine, but crackled like a green bayleaf cast into the fire: and so it did being cast immediately into the fire, but the crackling was less durable, by reason of the vivid fire into which it was cast. It is to be noted that this pottinger having been removed into the Sun, all the Serum was exhaled or incorporated into the mass, which was grown to the bottom of the Pottinger, and dried there, so that I scraped it off: whether that might add to the Phaenomena I know not. 17. The blood in that Pottinger where the spirit of Hartshorn was affused, being taken out and placed in an arched fire, rose up with an equal intumescence, as a cake doth in an Oven; it crackled much less than the unmixed mass of blood: It burned slowly, with a continual but not vivid flame, and in such a manner as if the mass had never taken fire, but only the smoke issuing from it; for one might easily see an interstice betwixt the mass and hover flame all the while, till it came to a perfect Ignition. 18. The mass which had spirit of Sal Armoniac affused unto it, being placed in an arched fire, did rise with an equal intumescence, but greater then that with the spirit of Hartshorn: it crackled less than that with spirit of Hartshorn: the flame at first resembled that of the other; afterwards instead of hover about, it seemed to issue immediately from the blood, and not to appear like a smoke that took fire within the arch; the flame than was vivid, and continued. 19 The fire being an exceeding quick fire, I poured some of the serous blood that was in the Pottinger, impregnated with the affusion of the spirit of Sal Armoniac, and as it dried it took fire presently, the flame resembled that of the former mass, only it wasted faster than that, being cast upon so quick a fire: The black Serum of the coagulated mass with affused spirit of Hartshorn, though cast into the same fire, would scarce burn at all. 20. I took some of the mass that was impregnated with the Sal prunellae, and placed it in an arched fire (the Serum or Solution poured off from it was insipid) it rose with an unequal intumescence copling, like a loaf, in the midst: I brought it to a perfect ignition and coal, yet did it not crackle at all, neither burn till the last, and then but a little, and with an interrupted flame which seized now on this, now on that part: nay, there was but very little sign of any Sal prunellae in it to sputter as it burned. 21. I told you how I poured some spirit of Sal Armoniac, upon the mixture of blood and a Solution of Allom, and of the odd coagulation that happened thereupon into white massulae which seemed like flesh when the blood is wasted out of it: I took of those incoherent flakes or massulae, and putting them to burn in an arched fire upon the fire-shovel, it run all off, upon a great ebullition, into the fire: I took the red hot fire-shovel, and placed some more upon it, which seemed to burn as Allom doth in the like case, and so stayed on it: but being put into the arched fire, and brought to ignition, it would neither flame, nor crackle, nor left any visible quantity of coal or ashes behind it, as if it had almost all evaporated. 22. These were the Phaenomena which I had opportunity to take notice of at that time: but I also left a Solution of the Alcali of Nitre of about three ounces with the Apothecary, if any else came to bleed there in my absence: upon bleeding, an healthy young man that was somewhat indisposed, some was suffered to stream into that Solution: at first it was of a florid red, but paler than blood usually is, resembling a bastard-scarlet: after some days standing I found it of a deeper red from top to bottom: one half of it was transparent like to the duller and more decayed sort of Claret: the other half seemed like Tent-wine, not diaphanous: on the surface there was a cremor which extended itself almost all over it: Upon pouring it out, it appeared all to be of a blood-red, only that which ran last was of a deeper die: at the bottom there was a kind of Gelatine like to that of red Currants, which rendered the one half of it opacous: it was no way dis- coloured, nor unequally mixed: the spirit of Sal Armoniac being poured on it, did render it fluid presently and transparent. Having occasion after some weeks stay at the Bath, to ride in extreme hot weather above 200 miles in a few days, and being tired with watching and the journey, and being wet very much with a great shower of rain at my return, I went immediately into the Cross-Bath for half an hour, to prevent any inconveniences that might befall me upon such travel: but at my coming out of the Bath I felt so violent a defluxion into my throat, and the adjacent Glandules, that I apprehended some danger of a Squinoncy, which yet I avoided by bleeding, purging, and other means together, with the use of the same Bath after all: when I was to bleed, I was willing to try some further Experiments in Liquors, different from the former, and the Observations I made were these. 1. I caused two veins to be opened in the left arm at once, and received one Pottinger out of the Mediana, and the other out of the Cephalica: my intent in that was to observe (as I had done once before in myself) whether the blood of two veins in the same arm would yield different blood: if so, than I thought that it might not be indifferent in what vein a man bleeds, though they all arise from one trunk of the vena cava; and that we might justly have regard to those cautions of our observing Ancestors, not to bleed those veins promiscuously, but some in one case, and some in another. I was confirmed in those sentiments by the Phaenomena I met with a second time in the trial, as other observations have satisfied me about the doctrine of revulsion, and its truth. Having taken one Pottinger out of the Mediane, and another out of the Cephalica, I stopped the Mediane, and continued to bleed into the liquors out of the Cephalick. In the first, issuing out of the two bloods, I could find no difference in the colour or consistence; but after standing three or four hours, that of the Mediane had much less of Serum in it: the Serum thereof seemed Limpid in the Pottinger: but that of the Cephalick was citrine-coloured: that of the Mediane somewhat of a volatile saline pungency upon the tongue, different from the taste, which the other Serum had, that being very salt: that of the Mediane had a bluish Gelatine gathered upon the top of the condensed mass of blood; the other had none, but was of a florid red on the top. After two days I came to look on them again, and upon turning the coagulated mass of blood in the pottinger, that of the Mediana had much more of black towards the bottom, than the other: and also a thinner surface of red then that of the Cephalick. 2. To carry on the Experiment of mixing several liquors with blood, I bled into some ounces of Aqua mirabilis, which grew deep coloured almost unto the top, which was transparent and of the colour of Mant-wine almost: after some hours the Liquor became of a bright beautiful Claret-colour almost unto the bottom, where there was an opacous, darkened settling, with an enaeorema of contexed filaments pretended to the top. The Wasps flocked to that glass in great numbers, and drowned themselves in it, not meddling with any other of the subsequent glasses. After two days was little changed, only the beautiful Claret was somewhat darkened. 3. I bled upon some ounces of Treacle-water, which turned as black as Ink presently, but continued the blood perfectly fluid: The red was so destroyed, that the Aluminous Solution did not equal it; there not being upon inclination of the glass the least sign of any incarnadine; and so it continued for two days, no variation happening. 4. I bled upon some ounces of Cinnamon-water, which turned of a pale red; i● I held up the glass to the light, it seemed almost to the top opacously red as Tent wine; but, if viewed otherwise it seemed of a paler red, approaching to bastard-scarlet. After a while it seemed as if all the blood were coagulated into one mass from top to bottom, subsiding a little within the tinged Cinnamon-water. Upon agitation and stirring with a knife, it appeared that the fibres of the blood were so destroyed, that this mass was no coherent thing, but broken into little massulae, or parcels of a pale red, such as the subsiding curds are in whey. After two days I viewed it, and found the Phaenomenon of the whole Glass to look cherry-coloured, but the incoherent massulae were of a pale red. 5. I bled into some ounces of Aqua Bezoarticae, that did coagulate with the blood, so that it all fell in one incoherent mass towards the bottom: but whether there happened to be a greater proportion of blood in the glass, or for some other cause, the coagulated blood filled almost all the water, much beyond what we observed in the Cinnamon-water: the consistence of the one, and the other massulae were like the curds in whey; these were of a pale red retaining to whitishness; and so it continued two days; the small quantity of water appearing in it giving no opportunity for further Observations. 6. I bled upon some ounces of Nantes-Brandy, it gave us a more tenacious curd then the former, of a pale red: but the mass and liquor was opacous towards the bottom, so as to appear like Tent-wine, in what light soever I placed it. After two days that of the Brandy which was fluid, (the curd not being answerable to the Aqua Bezoartica) was of a pretty florid red, the coagulated mass was of a brick colour. 7. I bled upon some ounces of Anise seed water drawn from the grounds of beer, it yielded a mixture of a deep blood red from top to bottom, somewhat transparent. The mass coagulated from top to bottom, the curd was of a deeper red than the others, and of such a tenaciousness as is to be sound in the soft curd of possets. After two days it turned blackish, the coherent curd being of a little lighter red. 8. My indisposition, and other cares permitted me not to prosecute these Experiments as I did the other: but one curiosity more possessed me, to put two drams of spirit of Hartshorn into a pottinger, and to bleed thereupon, to see if it would alter the Phaenomenon from what it is, if the spirit of Hartshorn be poured on the blood: I did so, and ● found at this time that it kept my blood from coagulating into such masses as otherwise it would, but the blood turned blackishly-red, and in it there was observed a crimson gelatine, which run off the knife as jelly of red currants would, when beginning to cool. After two days it continued still fluid, but blackish. I have sundry times tried that way of putting spirit of Hartshorn into the pottinger first, and then caused them to bleed upon it with this success, that immediately it spoils the red, giving it a more dirty colour, and casts up a mucous phlegm, (such as I never saw in any blood upon other Essays) just like what many spit and blow out of their noses in catarrhs: this covers all the pottinger, without any mixture of blood in it, and would be white, but that the subjacent blood gives it another muddy colour. The blood under it was always fluid, and unequally mixed with parts of a bright and blackish red. Whether my journey, or distemper prevented that appearance in my blood, I know not. 9 I had a Patient there which had unknowingly taken much of Mercurius dulcis in pills at Lo●●o●, to her great prejudice several ways: and though she had taken golden-bullets, and used other means to discharge her body of that troublesome Inmate, yet found little benefit: At the Bath I let her blood, and to try an Experiment I cast a Guinny into one of the middle Pottingers as she bled: I could observe no difference betwixt the blood preceding, and that therein: but in the afternoon I came and went to that pottinger which had the most florid and best coloured blood, and searching there found my gold, and that stained with white spots from the Mercury on the lower side. Whether the separation of the Mercury, or some other efficacy in the Gold (of whose power in such cases I can give good instances) caused that difference in the bloods, I cannot tell, having never tried it since. Being not well at Warwick, by reason of a violent defluxion into the Glandules of the Throat, I caused myself to bleed Octob. 20. 1. I took six drams of spirit of Heart's horn, not very well rectified, nor clear of colour, and put it into a crystal-glass; and bled thereupon about half an ounce of blood; it turned of a dark red presently, inclining much to black, though, as it stood, or as it was held on one side, you might perceive a lighter, but not florid red at the sides. It seemed fluid for two days; but as I poured it out it appeared to be very Gelatinous, and of colour like that which is become sanious, and degenerated into blackishness with keeping. 2. I bled upon the same liquor of Saltpetre, about half an ounce of blood, upon four ounces of liquor, at first the blood did turn on the surface to a bastard-scarlet (which is an effect every thing of Nitre mixed with blood so produceth) afterwards the whole blood sunk to the bottom, the upper part being all of one colour and consistence, such as is observed in the Serum of the blood sometimes, when the supernatancy is whitish, and not transparent. Being poured from the blood, I found that coagulated into a mass, which was all of a very natural red all over, only spotted in many places underneath with black spots. The concretion was so brittle, that it would not hang together, nor endure any light-pressure, but as it were melted, and seemed gelatinous. 3. I bled upon a Solution of the Alcali of Nitre; it appeared upon the first mixture like bastard-scarlet; then the blood sunk to the bottom, the top being transparent, yet of the colour of High-countrey-white-wine: the bottom seemed redder than that of t●e former; the limpid liquor being poured out, seemed all gelatinous, and had incorporated with it the serous part of the blood: the red at the bottom was fluid and not tenacious, but of the consistence that blood is of when it is hot, and newly received in a vessel out of the veins. N. B. After I had poured out the blood and mixtures out of the several glasses, and that the glasses had stood a while, I observed that that of the raw Liquor of Nitre, which remained in the bottom, did turn of a most beautiful red, as ever I saw in any thing: but that with the spirit of Hartshorn, or Solution of Alcali, etc. did not vary: after two days all the remains of blood in the several glasses turned blackish and sanious, only that with the raw liquor altered not. 4. I bled upon the liquors of Saltpetre which had passed the ashes, and on that which had never passed the ashes: both were of the same blackish and sanious colour (after the first bastard-scarlet was passed) both had on the top a certain cremor, which being cast into the fire discovered itself to be nitrous: both of them, though they were of such a dirty red inclining to black, yet were they of one consistence from top to bottom all fluid, nothing gelatinous, nor any one part blacker, or redder than the other. Which is very much, considering the difference of the two Liquors. 5. I bled upon the unctuous Mothers of Saltpetre, which turned at first to a bastard-scarlet: the blood did never mix with the Mothers, nor otherwise ting their colour, then as it cast a shadow by its innating on the surface of them. It coagulated on the top of the Mothers, being of colour all through exactly like to Ocher: the concretion was a quarter of an inch thick, a firm mass to se● to, like so much bees wax cast into a cake: I took it up in one mass with my knife but trying its tenaciousness, I found it as brittle as most short cakes are. Upon the surface, there was an appearance of certain striae, which might be saline. All the blood did not coagulate so, but underneath there was a quantity which in the glass was of equal dimensions with the other mass, it was of the colour of Ochre, and fluid, and would not mix with the Mothers at all: I took of the mass, and tried to burn it in an arched fire twice or thrice, it boiled and bubled up upon the fireshovel, like impure Niter, and so burned with a flashing, as if it had been most of it Peter, it never came to flame as blood doth usually; only one blaze as it were always hovered over it for a moment or two, not being continued to the body, otherwise then by a parcel of smoke issuing out them. 6. I took also two pottingers of blood, the first and the last of the blood I took away: there was no difference in the blood of one and the other; the coagulated mass well-coloured, of a good consistence, less of that black or melancholic crastament than is commonly found: the Serum well coloured, of taste brinish: I placed it in an arched fire, it rose up with a globous intumescence (but crackled not so much as at bath; though very much, and like a bayleaf) it burned with a continued, vivid, and lasting flame. I suffered a pottinger of the same blood with which this last Experiment was made, to stand ten days or more, in which time it was quite dried up into a hard fryable mass, the top of which was almost as black as Ink, the bottom having somewhat of a dark red in it. I cast a piece of it into a quick coal-fire; therein it crackled like unto a bayleaf, but burned with a short and weak flame. I placed another part of it upon a fireshovel in an arched and quick fire, where it crackled as much as the other did (and more than that part of the same blood which was burned in the foregoing Experiment of blood newly congealed, and separated from the Serum, which was in this last case dried into the mass) and it did burn with a vivid and continued flame presently. Which accident I take notice of, to show the different Phaenomena upon the divers way of burning the blood. I took a third portion of the said congealed and firm mass of blood, and put it to some cold water in a Glass, and it dissolved most of it therein, and tinged the water of as beautiful a red as any claret, though otherwise the mass were blackish, and had nothing of red but what was in the extimous crust of the bottom, which seemed of a most deep red inclining to black. I suffered two or three spoonfuls of Hogs-blood to run into a large Venice-Glass, in which was half a pint of the Mothers of Peter; I suffered it to stand some days, and coming then to see it, I observed that the Mothers were become opacous almost to the bottom, on the top was a mass of coagulated blood exactly resembling the colour of Ochre; it was so firm, that I took it with my knife in one entire piece, but I found the top and bottom of the mass (which was pretty thick) to be very soft, but not as it were fibrous; the middle was more firm: I put some of it upon a fire-shovel in an arched and quick fire, when it boiled up, and ran about, and by its sputtering discovered a mixture of Saltpetre: but it did not flame at all, though I brought it to ignition. Examineing the remaining Mothers, I found a sanguine mixture to float in, and slain the liquor of an Oker-colour, and some of it was aggregated into little masses or lumps, whose particles did not cohere by any tenacious fibres (indeed I have not been able to observe any tenaciously-fibrous coagulations in the blood of Hogs hitherto) but upon the least touch of my warn● hand, they dissolved or yielded unto the least pressure. Out of all which I intent to deduce, that some common Experiments may show that, which no Chemical Fires give any light unto. That there is a great diversity betwixt the blood of other Animals, and that of Men: because that upon the same Liquors they disclose different Phaenomena; and consequently that the Transfusion is a rash and unsafe attempt. I shall conclude with this intimation, that neither is the lood of several Animals, nor the blood of the same kind of Animals the same; but in taste and colour of the Serum there will be often a sensible difference, and it is rational to think the like of the blood itself: nor do they burn or coagulate alike, or with the like Phaenomena: nor is the blood of the same Men always the same, though he continue within the latitude of Health; and in diseases Epidemical let two bleed, and there shall often be no affinity The other day coming into my Apothecary's Shop, and finding one (not otherwise very ill) going to bleed, I sent for a bottle of that Lixivium of Saltpetre which had passed the ashes, and into the first pottinger which he bled, which seemed to have little of crimson in it, but a Serum of a dark-blew colour; I poured a little of it, and it turned black, though it continued fluid: Into the third pottinger which seemed better blood, with a red colour, I poured some of the same liquor, and it improved the colour, and kept it from coagulation awhile; what happened afterwards I had not leisure to observe. in the colour of their blood, or in the Serum, the one being white and turbid, the other Limpid, the Serum of the third citrine-coloured. And if so, what regulations shall we have for this operation: shall a transfuse he knows not what, to correct he knows not what, God knows how? This may become indeed that sort of men, being the worst and most irrational Empirics the Sun ever shined upon, as I demonstrate more fully in my Letter to a Physician, in a Parallel betwixt them and the ancient Empirics. Let them from these Observations draw their sophistical Conclusions for and against spirit of Heart's horn; for, and against spirit of Sal Armoniac; against Allom, and Treacle-water, and such like; till all the world come to admire them as much as I: And that there be a new History penned to render them as contemptible as this magnifies, by a Rhetoric that hath more of the nature of the Microscope, then of Truth. Miscellaneous Additions by way of Postscript. Whatever may seem to be said from hence in favour of the spirit of Hartshorn, is not so valid as may be imagined: for I have mixed a little of the Solution of the Alcali of Nitre (which turned Syrup of Violets green, and rendered it less fluid) upon the blood of a man, which was blackish, waterish, and ill-coloured, after it began somewhat to coagulate, and I brought it to a new fluidity, and as vivid a red as ever I saw: and so it continued for 24 hours; at my return after two days, I found the blood in the Pottinger, (by reason of the Sun on the window) all coagulated, and become friable; but even that it had visible signs of a remaining redness, which the other blood that had nothing effused retained not. Oil of vitriol affused to the Serum of blood, tinged with the crimson part, doth improve the red for an instant or two, but than it turns black and coagulates into a soft mass, that admits the least impression; the fibres being destroyed: but yet it burns rather better, brighter, and quicker than otherwise; being poured on the surface of coagulated blood, on the top whereof was tough pellicle generated; it did not eat the pellicle, but in one night reduced the Mass, almost to the bottom, into a consistence like to Bees wax, which burned well. In January last 1669. I had another occasion to bleed, but though the Phaenomena of my blood upon the Mothers of Salt peter were the same as at first; yet in the other mixture with Salt-peter-liquors, they were not: the blood separately taken seemed not to differ from the former, only the Serum was a little yellower: it did burn as well as before, but crackled much less. At the same time I caused an old man to be let blood for a catarrh and pain in his shoulder, which he used to ease with bleeding; the blood seemed very good and well-coloured; after it had stood a while I had the leisure to view it, and upon one pottinger of coagulated blood, I poured twenty drops of spirit of Vitriol, whereupon immediately all the top turned as white as milk, even the bubbles which seemed of blood before: whereupon I took another pottinger, and separated half the blood from the Serum, and poured on the blood and Serum some spirit of Vitriol as before: presently all the Serum became of colour and consistence like milk: the blood turned black, and hardened into a substance that cut like white-washed-wax: the other, at my return, I found of the consistence and colour of a common custard. The vitriolated Serum would not flame: the vitriolated blood did burn with a brisk but short flame: the simple blood would scarce burn at all, but with an hover and discontinued flame. I took also some of the pure citrine Serum of my blood, which tasted not very salt; I set it in the window for some time: during the frost it coagulated into a body of the consistence of butter in the heat of Summer: it gathered no Ice at all: the colour became less citrine; but still pellucid. I set it after some days to thaw; which it did immediately before the fire, but came not to its former fluidity, but like oil: after that, it coagulated with the warmth before the fire, and seemed exactly like to boiled Turpentine, but that it wanted the smell: it would not flame at all (though crackled much, as salt) yet I brought it to ignition. I did also take some Hog's blood again, and poured on the Mothers of Peter, it mixed not; only after some days some filamentary corpuscles subsided unto the middle of the liquor: the colour at first was a pale bastard scarlet: but after a day it turned to a darkish red, and so continued many days; and in its primitive fluidity, it suffering not any alteration, but being as fluid as when it first issued from the veins: it stood in the window all the frost, not changing or freezing at all. No more did another pottinger of my blood that was mixed with the liquor of Peter which had past the ashes: but that last blood turned very blackish. In fire, notwithstanding any thing I have done or purposed about the nature of blood, I do now desist from the Enquiry: the result of my thoughts being this, that there is a continual vatiation in the blood upon every disease, and often without it, during a state of health: that the blood of Individuals of the same kind differs not only from itself, but in each other individual: that no man can by reason of this consideration know what he would transfuse; nor what it is he would rectify. In a word, that 'tis most prudential to insist upon Experienced Methods in Physic, and that all fancies about spirit, salt, sulphur, fermentative fires in the heart, occasioned by heterogeneous mixtures, and the explications of the operations of Medicaments by the n●w Philosophers, either Chemical or others, are all vain, and cannot be allowed as a ground of practice, till justified by successful trials; seeing that not only the suppositions are false, but whilst the blood is sub diminio animae, effects upon it are different from what when it is separate: and I think I may thence conclude rationally, that 'tis not conceivable that the fabric of our bodies is purely Mechanical: for the liquors would have the same effect on the blood in the body, and without: which they have not. A REVIEW of the precedent Discourse against Mr. GLANVILL. AFter I had written the present Discourse, I was so unwilling to give any offence to the world, and so apprehensive lest my just indignation for the affront Mr. Glanvill had put upon my Faculty, should transport me beyond all fitting moderation, that I desired a Friend, (without further advising with me) to blot out whatever he might in prudence think equitable; by reason of his great cautiousness, as well as through that great haste and continual interruptions wherein the Treatise was penned; I find several passages either omitted totally, or not sufficiently explained; so as that I could not acquiesce in the publication thereof, without some few additions, partly to prevent som● cavils that might (though weakly) be raised against it, and partly to put every thing past dispute hereafter; that so I might not have any further occasion to write against our Virtuoso, nor his Abettors have any thing to do but to call in his Libel against the Physicians, and do some reasonable justice to those he had so arrogantly and injuriously insulted over. I desire my Reader to pardon me, if I have not in some circumstantial embellishmeats and regularity of procedure answered his expectation, since in the main I am sure I have outdone it. Whereas I charge Mr. Glanvill (page 2.) with not having read the Authors which he mentions. These words, Who can choose but smile, when he reads how Apuleius improved the Mathematics after Euclid? the whole passage should have run thus; Who can choose but smile when he reads how Apuleius improved Arithmetic? All that Apuleius did was to to translate something about Arithmetic into Latin, at such time as the Latins had no other Numerals then L▪. M. D. C, etc. And by reason of this performance of his doth Vossius give him a place amongst the Authors, not improvers of Arithmetic: and takes notice of him as the first that ever writ in Latin about that subject. Upon which account it Vossius de Scient. Math●●. ●. 51. sect 1. was judiciously done of Vossius to mention him there; but Mr. Glanvill is grossly mistaken here to name him, where he treats of such as advanced useful knowledge; which a bare Translation doth not. It is true, Vossius saith of Apuleius, Primus Arithmeticam Latinis literis Apuleius Arithmeticam Nicomachi Geras●ni Pythagorici Latin transtulit teste Cassiod●r● de mathem. discipl. cap. de Arithm. & Isidor● Hisp.

Mathem▪ Mr. Glanvill p. 47, 4●, etc. ● but consider the ridiculous characters he fixeth upon the Writers alleged, viz. Ptolemy of Alexandra made considerable improvements in Optics: and Alhazenus the Arabian is famous for what he did in it. From these Vitellio drew his, and advanced the Science by his own wit and their helps. * S. Stevinus both invented and writ such in all parts of the pure and practical Mathematics, in Geography, Geometry, Navigation, Mechanics, etc. that never did ●●y one, no, nor all the Virtuosos in England or Europe, ever equalled, or pursued: From hence 'tis apparent Mr. Glanvill, and his Abettors never read him: he was the first Proposer I know of, and before my Lard Bacon, of a Society to carry on Experiments in order to the rectifying many ●●●o●●s, ●nd improving many known truths▪ an Admirer of the Ancients, and th●●● learning. Stevinus corrected Euclid, Achazen, and Vitellio, in some fundamental Propositions that were mistakes; and in the room substituted considerable inventions of his own. Roger Bacon writ acutely of Optics.— Any man will grant, that he who gave so lame an account of these Authors, never was acquainted with them, nor understood particularly what they writ, or added of their own invention: whether new theorems, or different and new demonstrations of old known truths. Whereas he saith that Roger Bacon was accused of Magic to Pope Clement the fourth, and thereupon imprisoned: but the accusation was founded on nothing but his skill in Mathematics, and the ignorance of his Accusers.— Assertions of this nature are not so easily passed by, so many learned and judicious persons having reckoned him in the number of Magicians; such are Joannes Wierus J●. Wierus de praest●daem. l. 2. c. 2. and other Daemonographers. That the said Writer might declaim against Magic, or deny the possibility of it, and yet practise it, is an usual procedure with a Vide Bodin. in prae●. ad daemonomaniam. that sort of people: and that his works have in them sundry Propositions that are superstitious and magical is granted by Delcio; such haply was that which Franciscus b Se● Gabr: Naudaeus his History of Magic ch. 17. Picus says he had read in his book of the sixth Science, where he affirms, that a man may become a Prophet, and foretell things to come by the means of the Glass Almucheti, composed according to the rules of perspective, provided he made use of it under a good constellation, and had beforehand made his body very even, and put it into a good temper by Chemistry. As to what I say about Orontius, I add the words of Sir H. Savile in his Lectures, p. 71. Josephus Scaliger— hom● omnium mortalium, ne Orontio quidem excepto, 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉. Whereas I say (p. 3.) that the ancient Physicians did not only cure cut-fingers, and invented Diapalma and and other Medicaments in order thereunto. I add (what I know not how was omitted) that it is notorious how all our Herbals and Druggist's have explained the nature and use of Medicaments according to the Doctrine of the Elements, and qualities either arising therfrom, or from the peculiar mixture of the parts: and whosoever hath acted, or shall proceed according to those notions in compliance with the Ancients, shall not stand in need of any novel Method from the Virtuosos to salve a cut-finger. What I have said in the first and second sheet concerning the Barometer (as they call it) that it doth not determine exactly, neither the weight nor pressure of the air, wind, or clouds, is an opinion which the more I think upon, the more I am confirmed in; nor do I doubt that others will be as scrupulous as I in their assent to our dogmatizing Virtuoso, when they shall seriously consider what follows, and accommodate it to the Elasticity and gravity of the Atmosphere. First, when our Virtuoso speaks of the Elasticity of the Air, he understands thereby a body whose constituent particles are of a peculiar configuration and texture, distinct from what can be ascribed to earth, water, or fire? That the Air near the earth is such an heap of little bodies lying one upon another, as may be resembled to a fleece of wool; for this (to omit other likenesses betwixt them) consists of many slender flexible hairs; each of which may indeed like a little Spring, be easily bend or rolled up; but will also, like a Spring, be still endeavouring to stretch itself out again. For, though both these Hairs, and the Aerial corpuscles to which we like them, do easily yield to external pressures; yet each of them (by virtue of its structure) is endowed with a powe● Mr. Boil in his first part of Experiments of the Air: Experim. 1. I desire my Reader to take notice about the Elasticity of the Air, that the very names of Elater and Elasticity are of a more ancient mention then the being of the Society: Regius and Pecquetus use the terms: and that as to the expansive motion of the Air, 'tis proposed by several Cartesians, and before them by Kircher de maynet. l. 2. part. 1. progymn. 3. See also Mersenn. and Schottuss mechanic pneumat. hydraul: So that the Society can pretend to nothing but the similitude of a fleece of wool, and the explicating it by that way. or principle of self-dilatation; by virtue whereof, though the Hairs may by a man's hand be bend and crowded closer together, and into a narrower room than suits best with the nature of the body: yet whilst the compression lasts, there is in the fleece they compose or endeavour outwards, whereby it continually thrusts against the hand that opposes its expansion. And upon the removal of the external pressure by opening the hand more or less, the compressed wool does as it were spontaneously Page 59 expand or display itself towards the recovery of i●s former loose and free condition, till the fleece have either regained its former dimensions, or at least, approved them as near as the compressing hand, (perchance not quite opened) will permit.— Against this I except not only that this supposition is far from a sensible Philosophy; but that whosoever would weigh the Air exactly, and estimate the accession of weight which the Air receives from winds, clouds, or vapours (the thing Mr. Glanvill promiseth us) must weigh the Air singly first, and in its utmost degree of expansion, otherwise he can never tell what its gravity is, or what accessional it receives by its Elasticity, by exhalations and different mixtures: But this is not done by the Barometer (however it be essayed in the experiment of Aristotle very judiciously) but only an imaginary column or Cylinder of Air, and its pressure upon the Mercury is considered: which procedure seems to me as ridiculous, as if a man should lay a fleece of wool, or any other body upon any thing, and there being above that an incumbent body of lead (or the like) bearing thereon, yet should he proceed to say that he weighed the fleece of wool and not the incumbent lead: for as yet no discoveries have acquainted the world with the nature of that Aether which is above the Atmosphere, whether it gravitate or press upon the subjacent Thus the Moon according to the Cartesian● by its pressure upon the waters, causeth the Tides on Forth. Air (which a very subtle but rapid body may do) nor what effects the Libration of the Moon and other Planets may have by way of pressure upon the contiguous bodies, which pressure may be communicated to the terrestrial Air: and without the determination hereof▪ it is as vain to pretend to weigh the Air by this Barometer, as to determine of the weight of a board that presseth a Cheese in the Vat, without considering the superincumbent stone. Neither are we informed sufficiently what the Figure of the Aether is, whether it make a con●●●● and so encompass the Atmosphere; or also be interspersed with, and differently move therein; nor what effects those motions and agitations of it have upon the grosser corpuscles of the Atmosphere, (not only in abating of their gravity sometimes, but adding to them a levitation: nor is it explicated yet what effects the corpuscular rays of the fixed Stars and Planets may have in or upon the Atmosphere, adding to its gravity, (as 'tis just to imagine, since that eminent Virtuoso, the Pliny of our Age for lying, but a Virtuoso! could wash his hands in the beams of the Moon) or Elasticity, of which those intercurrent corpuscles seem not void (though Sir K. D of Simp. p. 43. Charlton de fulm●ne. not Airy) which constitute Thunder, Lightning, etc. or diminishing them both in order to the Phaenomena, which occur daily. Secondly, it doth not yet appear by any thing alleged by our Experimental Philosophers, that for certain the Air which encompasseth the Earth is a distinct body of a different structure from the Earth and Water that compose the Terraqueous Globe. Isaac Vossius doth think the Air to be nothing Is. Voss de motu mar. & vent. c. 21 p. 94. else but waterish exhalations drawn up by the Sun.— Credimus Aerem esse Aquam seu humorem dilatatum, ad legem aequilibrii quaquaversum se extendentem.

Mr. Hook Microgr. obst ●. p. 13. Atmosphaeram ex halitibus terrestribus & ●aperibus aqueis actione ●olis & reliquorum Astrorum concitari, inter doctos con●enit.

Scheiner ros vagin l. ●. p. ●. ex. from this Globe, whose structure must be as discrepant as the vapours are: and what a difference there is in them we may guests by the infinite variety of Meteors, Rains, Snows, Hail, Winds, Dews, etc. and their component corpuscles. If this latter be true, (as 'tis probable that it is; at least that there is no more besides but an intercurrent Aether or materia subtilis of the Cartesians) what becomes of this Elasticity, or pressure of this Springy Air so much talked of? Thirdly, 'tis necessary to distinguish betwixt the pressure and weight of bodies: for, suppose were a man pressed under a bended stick, or other springy body compressed, he shall feel a great oppression upon him, and be kept down to his great pain, not with the weight but spring of the said stick, or other springy body: and whosoever by the violence of the compression would judge of the weight of the incumbent body, would expose himself to laughter. Fourthly, 'tis possible for a body without any springiness or accessional gravity, to press downwards Acus omnino parallela horizonti, qua s●bito atque magneti aff●icatur, nullo modo fit gravior, tamen deprimitur, perinde ac si magnes esset acul subjectus. Finge nunc aliquem, qui haec a magnete fieri nesciat, is prosectò credet cum Aristotele acum tendere ad centrum mundi. Berigard. de terra: circulo 6. part. 3. above its weight: thus a needle touched with a Loadstone declines from that line in which it hung parallel to the Horizon, without any addition of weight: which is demonstrable from the variety of its declination and restitution: and 'tis as indubitable that such declination of it carries with it something of pressure. Fifthly, we are to consider the nature of the Earth, whether that be a Magnet, or no: for if it be such, (however the Magnetism be explained▪ whether according to the Cartesian Hypothesis, or that of Berigardus) instead of weighing the Air, we deceive ourselves as grossly as if we took the impulse with which Iron runs to the Loadstone for its weight: and thus in some cases we shall weigh things by their ascent, which is inconsistent with the common notion of weighing things. Sixthly, to wave the unestablished notions of Gravity and Lenity, and to abstract from all the preceding considerations, I say, that even so this opinion of the Aerial Column pressing down upon the Mercury is false: since in a body so unequally mixed as the Air is often (and it cannot be disproved that 'tis ever otherwise) it is impossible to imagine that the pressure or gravitation is by way of a Column or Cylinder. Imagine the Experiment to be tried by six or more weights pressing at one time upon the Mercury, would any man in his wits say, that this joint pressure were cylindrical? consider but the variety of mixtures in the Air, (and the separate pressures that are consequential thereunto▪ which the contemplation of the clouds will lead us into, and 'tis the same thing. Were a man swimming in that concourse of water in Hungary, where the unmixed rivers flow in one channel, and his body so placed that part of it were in one stream, and part in another,) would you say that the incumbent water did press upon him in a Column or Cylinder? But to proceed further, if it be true that the superior part of the Air or Atmosphere, which transcends the mountainous asperities of the Earth, hath another motion or lation then that which is more low, (explain it either the Aristotelian way, or according to Galileo, Vide Galilae●●n system. ●●sm dial. 4. ●●▪ 32●. edit. in 410. and agreeably to the motion of the Earth) if this be true, (as I take it to be now) how can we determine of the Gravity of the neighbouring Air by this Experiment? and how vain is this notion of a Cylinder? for in a fluid agitated with different motions as the subject Air is by repercussion from the Hills and Plains, (which begets vibrations and undulations God knows what it suffers upon the generation and motions of Meteors; and where the superior part hath a motion different oftentimes from the other, of whose rapidity we are as uncertain as of its structure, and texture, (and we see that the rapidity or swift motion of an heavy body takes it from its pressure and gravity how can any man talk of Aerial columns, much less pretend to weigh the Air incumbent, and to determine exactly of any accession of weight, as M. Glanvill professeth to do? Besides, if heavy bodies do not gravitate in a straight line, but describe the circumference of a Circle, or some such line, (as new Philosophers hold in opposition to Aristotle) and if the Atmosphere be to Vide Galilaeum de system. mundi dial. 2. pag. 119. edit. in 410. Sectatoribus Copernici opus est dicere (quip qui ponunt orbem magnum circulo ferri) morum gravis deorsum esse per lineam curvam vel instar quadratricis Nicomedis, vel circulari ut Galilaeus contendit. Scipio Claramont. de univers. l. xij. c. 20. be reckoned amongst the bodies that gravitate, how can we imagine this gravitation to be performed by way of a column or cylinder? Moreover, this Atmosphere can no way be considered to press cylindrically▪ if we consider that in every part of it there are continued exhalations, and smoke ascending through it, so that the weight of it must needs be abated by the ascent of those ●apors ● and what we experiment here is not the weight of the A●● properly, but the super-ponderancy or over-weight of it. The Atmosphere seems to me constantly to resemble a Glass in which water is poured on wine, and the wine is ascending through each part of the water indeterminately; if it be thus, and that the ascending vapours carry a great force with them, (which any man will grant who considers the weight Vide Sanctorii medic. static. Hanc Aeris con●●●tionem demonstrat vel ipsa saliva ex alto demissa, quae dilaceratur prope terram in quam conciratus aer impingens ad salivam redit, eamque discerpit. Berigard. circ. Pisar. part. 3. circ. 6. de terra. of the smoke, in comparison to what remains of the wood and coal that is burnt: and who statically regards the steams transpiring from our bodies: and how that spittle, which in an entire body issues from our mouths▪ descends till near the ground it be dissipated and distended) I cannot imagine how it can be said that we thus measure all the degrees of compression in the Atmosphere, and estimate exactly any accession of weight which the Air receives from winds, clouds, or vapours. To conclude, if the Air do thus press upon the Mercury, how comes it to pass that there is no difference when the Experiment is tried in a chamber (where the incumbent column is less than abroad) and in the open Air of the same level? Why doth it not press up water (or other liquors) in the Why doth not this Cylinder of Air which so presseth upon the Mercury, depress a leaf of Gold, but suffers it to fly up and down? like Syphon to an height as different as is the disproportion betwixt the gravity of Mercury and water: which I have not heard it doth; yet the proportion betwixt Mercury and water in gravity is 1 ●. 134/●. In fine, how is that true which Mr. Hooke saith, viz. Mr. Hook in the Preface to his Micrography. That he contrived an instrument to show all the minute-variations in the pressure of the Air: by which he constantly found, that before and during the time of rainy weather, the pressure of the Air is less, and in dry weather, but especially when an Eastern wind, (which having passed over vast tracts of Land, is heavy with earthy particles) blows, it is much more: though these changes are varied according to very odd Laws. If this be true, (as I am apt to believe it is) with what face can our Virtuoso tell us, It is concluded, that such a Cylinder Page 61. of the Air as presses upon the Mercury in the vessel, is of equal weight to about 29 digits of that ponderous body in the Tube. Thus it is when the Air is in its ordinary temper: but vapours, winds and clouds alter the Standard, so that the Quicksilver sometimes falls, sometimes If you would see how true Mr Glanvill speaks, read Mr. Boil his eighteenth Experiment, and the defence of it against Linus: there you will find that the Mercurial Cylinder did in winter sometimes correspond with the weather Glass and sometimes vary: and the reason Mr. boil gives, is such as takes off from the certainty of Mr. glanvil's CONCLUSION. rises in the Glass, proportionably to the greater or less accession of gravity and compression the Air hath received from any of those alterations: and the degree of increase beyond the Standard, is the measure of the additional gravity. Is not this prettily said by a man that writes a year after Mr. Hook, and more after Mr. boil? How unacquainted is He and his Assistants, even with the Writings of their fellow- Virtuosos? And if we may be allowed to transfer the Fool's Cap from the Ancients for concluding too soon, may we no● crown the heads of our Virtuosos now therewith? And how careful the R. S. is in making good their promise to Olaus Borrichius, that what their Members should write, the whole Society would be responsible, let any man judge that considers how Mr. Hooke, and Mr. Glanvill (I beg Mr. Hook's pardon for the unequal comparison) disagree; and Dr. Henshaw (another Virtuoso) differs also from Mr. Glanvill, saying, That the Quicksilver Tube will not give so exact an account of every small difference in the pressing Air, as the THERMOMETER! what confusion shall we be reduced unto in time, should these contradictious Experimentators proceed as they have done! I shall here add, that I do conceive that this notion of an Aerial column gravitating upon the Earth, or subjacent body, was framed in imitation of the Hypothesis of Simon Stevinus, the Teacher of Mathematics to Grave Maurice of N●ssau, in his fourth book of hydrostatics, where he insists much upon this Aqueous Column; but 'tis observable that that judicious person, the better to make out his Theorems, presupposeth such things as give some repute to my objections about the Aerial Cylinder or Column, viz. 1. Aquam omnibus partibus esse ponderitatis Homogeneae. 2. Cujusvis aqua superficiem planam & horizonti parallelam esse. 3. Aquae fundo horizonti parallelo tantum insidet pondus, quantum est Aqueae Columnae cujus basis fando, altitudo perpendiculari ab aquae superficie summa adimam demissae sit aequalis. Out of this last Proposition, and the demonstration and consectaries thereof in him; 'tis manifest, that he supposed not one of his assertions would hold (though the Phaenomena were the same in nature) as he worded and explained them, if that he did not free his aqueous Column from any oblique S Stevinus hydrostat Elem. l 4 Theoorem 8. pressures, and make it rectangular. And as for his Postulatum, that the surface of the water is plain, flat and level; he confesses it is not so really, viz. Quatenus pars est sphaericae sive mundanae superficiei; mundanam autem superficiem dicimus sphaerae cujusvis mundo concentricae: he only professeth to assume it as true, because in hydrostatics, things happen as if it really were so; whereupon he scruples not to make use of a supposition, which is really, confessedly, and demonstrably false, as long as it conduceth to practice, and serves his turn as if it were true, without pursuing a more tedious, and not more useful Hypothesis agreeable to Archimedes.

Out of all which I am more and more satisfied of the validity of my former doubts against this so much concluded upon Aerial Column, to the explanation whereof I find no such cautions, or previous suppositions used, to take off the edge and force of such objections: neither indeed have I yet met with any thing of that subject proposed in a Scientifical way; and therefore much how it comes to be concluded upon so as Mr. Glanvill represents it to be. Whereas I have said, that the gravitation of the Air (even Elementary) is an opinion of Aristotle's, and that his Experiment was tried by Claramontius; I add, that the verity of that trial (though indeed it extend only to the impure Atmosphere) is attested by Ricciolus in these words, Duo Ricciol. Almag●nov l. 2. c. 5 sect. 4. quarto Aquam, & Aerem nostrum habere aliquid levitatis gravitati admistum, ut vi illius adscendant, ut sint supra id quod est ipsis gravius; & vi hujus descendant.

Thus the incomparable Ricciolus, whom I may as well reckon amongst the Peripatetics, as Mr. a Against Hobbs c. 3. boil doth Schottus: and how true that Aristotelean Experiment is Mr. boil demonstrates in his b Experiments of Air. Exper. 6. and against Hobbs c. 3. pneumatick discourses. And though the works of Galileo, Kepler, Mersennus, Gassendus, Pecquetus, Paschal, were lost, and were as ignorant as some Virtuosos of their trials about the weight of the Air; yet would not the Assertion have seemed so strange and incredible as Mr. Glanvill represents it to be; for though Maynenus deny it, yet he brings in this Objection.

I have not Schottus by me at present; neither is there need of any further Inquiries; for I have sufficiently demonstrated that the Gravitation of the Air is an opinion of Aristotle, Averro, and other Peripatetics, though not generally received by that sort of Peilosophers: and that it was truly and experimentally demonstrated by them, especially as far as the Atmosphere is concerned in the Question. I have also made it apparent, that the Barometer, or Mercurial Experiment doth not discover the weight of the Air with any certainty; much less, all the degrees of it: That the pressure of the Air is not by way of a Cylinder or Column; and that the Barometer had not its original but denomination from the R. S. they were, as I may term them, the Godfathers, not Parents. The World may justly say of the Honourable Mr. boil, that he hath improved the Experiments of his Predecessors, and represented them more accurately; and of Mr. Glanvill and his Assistants what it pleaseth. In the marginal note (page 15.) where I say, that perhaps it is not true that Aristotle had any hand in, or was privy to the impoisoning of Alexander; I add that Pausanias after he had spoke of the Stygian water, and its strange property, doubts whether Alexander were made away by such means, or no: 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉. This he says (in Arcadic) without reflecting any way upon Aristotle as one concerned in the report. And Arrianus who writ the life of Alexander, out of the Memoires of Ptolomaeus Lagides (who was present when that great Prince died) avows, that he died of a surfeit: yet he relates sundry rumours about his death, one whereof is, that Aristotle (being fearful of Alexander after the death of Calisthenes) should prepare the poison for Antipater, to be sent him: but concludes thus, 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉. Arrian. de expedit. Alexandr. l. 7. Whereas I reflect (page 16.) upon that passage of Plato, 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉, and what Mr. Glanvill saith, That without Geometry we cannot in any good degree understand Mr. Glanvill p. 25. the Artifice of the Omnisoient Architect in the composure of the great World and ourselves: and that the Universe must be known by the Art whereby it was made.— There should have been a Chasm made for some passages, I know not why omitted. I add therefore, that it is not revealed unto us that God made the Universe according to that Art, and it seems an Additional to the first Fiat, or let there be— in Genesis, to say his commands were regulated by the rules of Geometry, and his powerful and omnipotent word confined thereunto. Had Mr. Glanvill been pleased to consult the fathers, he would have found that this Tenet of his is no primitive notion: and that particularly Eusebius hath refuted Euseb. de praep. Evang l. 14 c. 4. it, denying that God in his Works is obliged to Geometrical numbers; and that Socrates (whose authority is greater than Plato's) did place no great value on those Sciences: that the first Christians did slight the knowledge of them as useless to Piety and knowledge of God; because my opinion about these things is agreeable to that of the first Christians, and of Socrates; I shall insert the whole passage, as it is translated into Latin in the Paris Edition. Euseb. praep. Evangelicae. l. 14. c. 10, 11. edit. Paris. 1628. Primum tamen quoniam Mathematica illa sua tantopere jactare solent, prorsusque necessarium esse dictitant, ut quisquis comprehendendi veri studio tenebitur, Astronomiam, Arithmetriam, Geometriam, Musicam, illa nimirum ipsa, quae ad eos a Barbaris profecta esse jam ostendimus, persequatur: (his enim qui carebit, doctum perfectumque Philosophum esse neminem, imo rerum veritatem ne primoribus quidem labris digustare posse, nisi qui harum ante rerum animo cognitionem impresserit:) deinde hanc suarum artium peritiam magnificentius ostentantes, aethere sese medio sublimi●s propemodum incidere, numerisque suis ipsum quoque Deum circumferre arbitrantur: nos vero qui similium disciplinarum amore non flagremus, nihil a pecudibus abesse existimant, deique propterea nunquàm nunquam reipaulo gravioris notitiam percepturos esse pronunciant: Age, hoc ipsum quam pravum sit atque distortum, vera laminis loco ratione proposita, sic tanquam ad libellam & regulam exigamus. Erit ea quidem ejusmodi, quae Graecos, innumerabiles, infinitosque Barbaros complexa; alios tametsi his artibus doctrinisque paratos, nec Deum unquam, nec honestae vitae rationes, nec omnino praeclarum & utile quid percepisse; alios, ut ab omnium disciplinarum studio destituti essent, religiosissimos tamen ac sapientissimos extitisse demonstret. Enimvero quaenam hoc in genere Socratis illius, qui ab istis omnibus tantopere celebratur, sententia fuerit, e Xenophonte intelliges, si modo ei suis in Memorabilibus haec scribente fidem adhibebis. Docebat, inquit ille, praeterea, quatenus cujusque rei peritum esse hominem bene institute oporteret: principio Geometricae dandam eatenus operam esse dicebat, ut siquando res pasceret, dimensam rite terram vel accipere ab alio, vel alii tradere, vel eam dividere, vel opus aliquod designare posset. Id porro tam esse ad discendum facile, ut qui dimensionem attendere voluerit, idem simul & quanta sit terrae magnitudo assequi possit, & quaenam ejus metiendae ratio breviter admodum expediteque cognoscere. At ejusdem in Geometricae study, ad illas usque descriptiones intellectu difficiliores quenquam progredi, Socrati non placebat. Cui enim bono futurae illae essent, videre se, tametsi ne illarum quidem imperitus esset, rogabat. Enimvero, ad exhauriendam hòminis vitam cum satis illas esse, tum aliarum interim & plurimum & utiliorum doctrinarum studia impedire. Astronomiam similiter eatenus complecti solum jubebat, ut noctis, mensis, a●nique tempora cognosceres, atque hujus cognitionis open, siquando vel iter, vel navigatio suscipienda esset, vel agendae forent excubiae, vel in aliud quidlibet quod noctis, mensis, aunique spatio fieri solet, incumbendum, signis ad ea omnia suis quaeque temporibus obeunda, certioribus uterere. Atqui haec nihilo difficilius tam ex nocturnis venatoribus, quam ex navium gubernatoribus, & aliis quamplurimis resciri posse, a quibus eorum peritiam suae cujusque partes officiumque deposcat. At eandem artem eo usque persequi, dum ea quae non codem motu circumferantur, stellasque simul errantes & vagas distinguere noveris, adeoque in earum abs terra intervallis, conversionibus causisque rimandis aetatem viresque consumere, id vero graviter imprimis ac serio prohibebat, quod multum hujus etiam opere pretium videret, tametsi ne in istis quidem rebus hospes ipse ac peregrinus esset. Addebat, conficiendae hominis vitae illas quaeque satis futuras, quae interim a pluribus utilioribusque studiis avocarent. Postremo quibus coelestia quaeque rationibus Numen moderetur, investigari nolebat, quod cum eo ab hominibus aspirari non posse, tum minus cum diis probari existimaret, qui quae prompta notaque esse noluissent, inquireret. Nec minus illi, quem ea vehementius cura destineret, insaniae periculum imminer● dicebat, quam Anaxagorae, qui explicatus a se deorum Machinas tantopere gloriabatur. I shall add, that if God Almighty be regulated by the rules of Geometry, and mechanical motion in the management of this world, and that the fabric of things is necessarily established upon those Hypotheses, I cannot any way comprehend how God can do any miracles: how the Sun should stand still at the command of Joshuah, or the shadow go back on the dial of Ahaz: or how there could be a general deluge; or such an Eclipse as is related at the death of our Saviour: or that the fire should not burn, or destroy the three children: in which, and other cases, if God were not tied up to this Art, I do want proof (till he declare it) that at other times he acts altogether agreeably to it. This opinion of mine hath been hitherto the most Christian Assertion, and held most consonant to Piety, and hath been amply maintained of late by Dr. Henry More, in opposition to what the Royal Society lays down in their History; That Generation, Corruption, Alteration, and Mr. Sprat pag. 312. I wonder that such effects should be attributed by them to the bare concourse and meeting of corpuscles of differing figures, magnitudes and velocities; without taking notice of that alteration of texture, and of the figures of the concurrent particles, without which Cartesianism, nor the other Mechanical Philosophies can subsist: and not so without allowing the constant assistance of God, directing and ordering lay- Mechanism. So des Cartes Princ. Philos part. 2. Deu● materiam simul cum motu & qui●te in principio ereavit; jamque per Solem suum concursum ordinarium tantundem motus & quietis in ea t●ra, quantum tunc posuit conservet. Oh! rare and sensible explication of things! God Almighty in a peculiar matter agitates matter! must we thus explain the secondary and mediate creation of the world in six days, whereas the like productions have not happened in so many thousand years as are lapsed since! Besides, whatever our Virtuoso thinks of the Eternal Generation and Incarnation of the Son of God; He doth not except in this Assertion the Generation of mankind in the ordinary and natural way. all the vicissitudes of Nature, are nothing else but the effects arising from the meeting of little bodies, of differing figures, magnitudes and velocities. Then which opinion there can be nothing more pestilent and pernicious; and Dr. More, albeit a Member of this Society heretofore, (for he allows nothing to it now) yet a pious one, professeth that this Mechanical Philosophy doth incline to Atheism: neither would he approve of those deductions as necessary, but ridiculous, when I upbraided him lately with that nonsensical and illiterate History, Mr. Sprat p. 348. 'Tis true, his, [viz. The Experimental Philosophers] employment is about material things. But this is so far from drawing him to oppose invisible Being's, that it rather puts his thoughts into an excellent good capacity to believe them. In every work of Nature that he handles, he knows that there is not only a gross substance, which presents itself to all men's Eyes; but an infinite subtlety of parts, which come not into the sharpest sense. So that what the Scripture relates of the purity of God, of the spirituality of his Nature, and that of Angles, and the souls of men, cannot seem incredible to him, when he perceives the numberless particles that move in every man's Blood, and the prodigious streams that continually flow unseen from every body: having found that his own senses have been so far assisted by the Instruments of Art, he may sooner admit that his mind ought to be raised higher by an Heavenly light in those things wherein his senses do fall short. If (as the Apostle says) the invisible things of God are manifested by the visible: then how much stronger Arguments has he for his belief, in the eternal Power and Godhead, from the vast number of creatures that are invisible to others, but are exposed to his view by the help of his Experiments? My censure upon this place is, that if his Experimentator have any skill in Logic or the ways of arguing, though from the Rules of Mechanism, and the contemplation of visible bodies, he may proceed to the allowance of invisible and insensible corpuscles, yet shall he still confine his progress and ascent within the nature of matter and corpuscles, and never apprehend (upon those grounds) the being and operations of an immaterial, omnipresent Deity acting by the Word of his Power and Will: nor the incorporeal nature of the soul of man. Such a Transition ad genus a genere, or 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉, he that owns those principles cannot assent unto, if he understands himself, and argue not so as to allege, One Proposition for sense, The other for convenience. Where I speak of Archytas (pag. 18.) that he was a practical and Mechanical Philosopher, contrary to what Mr. Glanvill asserts (pag. 27.) I shall add his life; As it is briefly written in Ricciolus thus. Archytas Tarentinus Pythagoreus nobilis, Mathematicarum peritissimus. quem ut Ricciolus in Chronic part. 2. praefixo ad Almag●st. nov. in Archytas. una cum Timaeo cognosceret Plato, in Italiam navigavit, ut ait Cicero.

Te maris ac terrae numeroque carentis arenae, Mensorem cohibent Archyta. Neither is Mr. Glanvill mistaken there in reference to Blancanus saith of Archytas, that he was Mechanic● Inventor, in Chronol. mathem. secul. 5. A●d Will● Snelliu● in his Preface to the Hypomn. mathem. o● S. Stevinus, doth reckon upon Archytas and Eudoxus as c●●nent for practical Mechanics. Mr. Hook micrograph. p. ●10.

Blanoan. in Chronol. Mathemat. Sevil. 5. Whereas I say (page 22.) that the Royal Society were not the first that applied themselves to the observing the forms of Animals, etc. by the Microscope: I add that Zucchius did not only precede them in the attempt, but seems to have had hetter glasses to that purpose than they: for whereas Mr. Hooke in his description of a Flea says of the Eyes only this, that the head is on either side beautified with a quick and round black eye: the more accurate Zucchius saith, Novissims Microscopio parato ab excellentissimo Vitrorum in omnes formas ad propo●itos usus formatore D. Eitstachi● Divinio Septempedano, spectavi meis oculis senescentibus Oculum pulicis, distinctis in eo albescente Sclerotide Cornea, & per corneam Iride oculi. And in the description of the feet of a Fly, and the feather of a Peacock, I observe that there is such a difference betwixt those two Writers, that as one of them must needs be in an error, so I am apt to think that our Virtuoso is the person: see Mr. Hooke p. 167, 168, 169, 170. and Zucchius Philos. oped. part. 2. tr. 3. c. 7. sect. 4. pag. 349, 350. If England do yield better Microscopes than those of Eustachius Divinius, than I am ready to change my judgement. Where Mr. Glanvill speaks of going to the World of the Moon, and I animadvert upon the difficulties of the journey▪ and that his lodging will be too hot for him; add in the Text these words page 43. Besides the other difficulties of the journey, 'tis further considerable, that from the Centre of the Earth to the Moon, according to the calculation of Tycho Brahe, there is near 56 semidiameters of the Earth, which is about 192416 Van. E●●ens Mathem recreations pag. 220, 221. miles: and admit it be supposed that Mr. Glanvill fly 20 miles every day in ascending towards that world, he should be above 15 years before he could come to the Orb of the Moon. Where I speak against the accommodating of Scripture to common railing, p. 49. I add, that not only the Council of Trent (— fas est & ab hoste doceri) hath prohibited Sess. 4. that any should apply the holy Scripture ad scurritia, fabulosa, vana, adulationes; but also that the first Council at Milan, forbids the using it ad ●jocum, ostentationem, contumeliam, superstitionem, impietatem. And, to upbraid our Divine-Railleurs a little more, an ancient African-Council decrees, Si Clericus, aut Monachus verba scurritia, jocularia risumque moventia loquitur, acerrime corripiatur. The words of which Canon, (viz. Scurritia & jocularia) are by a learned Frenchman rendered raillery.— Nous avons le Canon d' un ancient Concile d' Africa, qui parle en ces terms: Si quelqu' un du Clerge ou si un Religieuse dit des paroles de raillery, des choses plaisantes & enjouces, qu' il soit chastie tres severement. Qu' eussent dit a vostre avis ces bons Peres si ces railleries eussent este terees de l' Escriture? This Question hath been agitated with much wit and address in French, betwixt Mr. de Girac and Mr. Costar in sundry books, wherein any man of common reason and piety, will give the advantage to adversary of Voiture, who is justified by the concurrent opinion of Balzac in his remarks sur les deux sonnets: and to these Writers I refer our Virtuosos, such as reckon upon all other learning as Pedantry, may inform themselves thence as out of Writers which transcend not their breeding and studies. Whereas (pag. 58.) I speak somewhat in commendation of the ancient Aristotelean Monks, I find that their esteem is much advanced by the learned Gabriel Naudaeus in these words. After the last taking of Constantinople, Learning began to creep out of Monasteries, which for all the time before Gabr. Naudaeus Hist. of Magic c. 7. had been (as it w●re) public Christian Schools, where not only youth, but also such men as would apply themselves that way, were instructed in all manner of Disciplines, Sciences, and Morality, and that to such an height, that not content with that so famous Quadrivium of the Mathematics, which, besides all that is now shown in Colleges, was then taught, Medicine both as to Theory and Practice, was so well cultivated, that we need no more to convince us how expert they were therein, than the Writings of Aegidius, Constantine, and Damascene, Joannitius, Peter of Spain, and Turisanus. So that it were easy for me to answer them who charge them with illiterature and ignorance. Where I speak out of G. Hoffman and others, that it is sufficient for a Physician that he proceed upon such rules and methods as may most commodiously guide him in his practice, without being solicitous whether they be rigorously and philosophically true: pag. 75. I add, that there are others as eminent as any that ever pretended to cure, which concur with me in this opinion. As Avicenna and Riolanus; the words of the latter in his Examen of Harvey, c. ●9. are these. — Quapropter cum Avicenna doctr. 6. cap. distinguo sermonem utilem a vero; Medicus qua Medicus, inquit ille, non curate, quid in veritate sit, sed contentus est Phaenomenis quibusdam, quae sunt satis illi in curatione morborum. I add unto the passages (pag. 97.) which relate unto the diligence of the Ancients in Dissections, this: That the Ancients, and particularly the Peripatetics were very curious and inquisitive into Anatomy appears by this passage out of Chalcidius, in his discourse upon the Timaeus of Plato; he lived about one thousand one hundred and seventy years ago, and the passage (which relates to the Platonic notion about vision) in the Latin Edition of Meursius, (pag. 340) runs thus. Quare faciendum ut ad certam explorationem Platonici dogmatis. commentum vetus advocetur medicorum, & item Physicorum, illustrium sane virorum, qui, ad comprehendendam sanae naturae solertiam, actus humani corporis, facta membrorum exsectione, rimati sunt: qui existimabant, ita demum se suspicionibus, atque opinionibus certiores futuros, si tam rationi visus, quam visui ratio concineret. Demonstranda igitur oculi natura est: de qua cum plerique alii, tum Alcmaeus Crotoniensis, in Physicis exercitatus, quique primus exsectionem aggredi est ausus; & calisthenes, Aristotelis auditor; & Herophilus, multa, & praeclara in lucem protulerunt. Out of which it is manifest that the Ancients (especially the Aristotelians; for such were Calisthenes and Herophilus) did with some curiosity examine the Phaenomena of nature, and regulated their opinions by sensible experiments; and that this was the practice of most of the eminent Physicians and Naturalists of old. The Letter of Hypocrates to Damagetas mentioned pag. 89. (though cited as genuine by Galen) is suspected by Jo. Baptista Cartes. miscell. medic. dec. 1. c. 4. Caeterum & hac Epistola, quae sub nomine▪ Hippocratis circumfe●tur, suspecta est mihi, primum quia▪ Diogenes Laertius lib. 9 in vita Democriti scribit illum nequaquam ridentem, quanquam concedat ab Hippocrate fuisse visitatum (non quidem ut ipsum sanaret) quo tempore jam Democritus erat decrepitus, nec amplius aptus sectioni cadaveram: nam Hypocrates 436 annos ante Christum natus; Democritus vero 492 ita ut ita ut Democritum nativitate secutus sit Hypocrates 56 annis: & tum sive ad videndum, sive ad sanandum eum conveniret, vigesimum quintum annum attigisse verisimile videtur: cum tunc temporis Hypocrates medici famam adoptus esset, quod non poterat nisi per longum temporis cursum & varia experimenta in Medicina facta sibi comparare.— Sed probandam provectiorem Hippocratis aetatem, & majorem senectam Democriti, ejusdem Laertii testimonium extat dicentis; Ultimum, quod in vita Democriti legitur dictum, aut factum, fuisse illam cum Hippocrate collocutionem: atque annum agentem 109. ab hujus vitae Statione decessisse. I find also that Menagius suspects those Letters, though he confess Menag. in Di●●. Laert. l. 9 p. 238. them to be very ancient. Extant hodie Hippocratis de sua ad Democritum profectione Epistolae, sed supposititiae, licet perantiquae. Whereas I say pag. 114. that I have observed in some that their pulses have suffered no alteration, at least kept no time, or palpitated as did their hearts. I shall illustrate this with an observation in a young Lady, which I had too fatal an opportunity lately to make: she died of a very malignant Fever joined with the Measils: two nights before she died I watched with her, and frequently observing the variety of her pulse, I determined to mind whether there were any such alteration in the beating of the Heart, as I then observed in her Arteries: I laid my hand upon her Breast, and I found that her heart did not beat as usually it doth, the b●●e erecting itself, and impelling the left side, but it seemed like a great bullet (transcending any proportion that is natural to the Heart) as it rolled in the Thorax from the right to the left side (as much one way as the other) with an uniform and equable revolution, and thus it continued to do for an hour; during which time I observed all the varieties almost that are recorded about evil pulses: as quick, slow; great, small; unequal, deficient, dicrotus, etc. Nor is this new; for Riolanus saith in Exam. Harvey c. 3. Notavi multoties in palpitationibus cordis vehementibus arterias non sequi motum Cordis, sed bis terve pulsare Cor pro una diastole Arteriarum: quod indicat Arterias in sanis & aegris corporibus, non semper sequi motus cordis. So doth Mercatus teach, Fit interdum palpitatio cordis nihil mutatis pulsibus. Tom. 2. de Philos. differ. l. 2. tr. 1. c. 28. & tom. 3. l. 2. c. xj. Since the writing hereof, being casually in the shop where an old man was blooded, who upon the healing up of an old sore in his leg, was very ill: I observed his blood to have very little of what was crimson in it: but it seemed all a fluid Serum to the bottom, (which was pellucid, not of a turbid white,) in some Pottingers: in one Pottinger that ran last, it was coagulated into a thicker mass, on the top whereof was coagulated a translucid gelatine over most of the Pottinger, the rest being of a fluid Serum like to the other: I took some spirit of Vitriol, and poured a pretty quantity, (viz. about 20 drops) on that which was partly coagulated upwards, partly not: and all that part which was not blood, did coagulate into a mass like unto the white of an Egg when hardened by the fire, but without that smell which is usual to it when coagulated upon a gentle fire: the blood under it coagulated into a consistence much like wax: but of a dark red inclining to black: into another Pottinger I poured some of the salt-peter-liquor that had passed the Ashes; but this latter caused no change at all: I then poured on the same some spirit of Vitriol, as in the other, and it did immediately turn lacteous, and coagulated into a mass like to that of ordinary custards: and the blood under, which seemed but very little, and scarce coagulated, appeared thereupon as a large quantity, equalling three parts of the Pottinger, upon which all the Serum was thus coagulated. I went to b●●n these: that blood which had only spirit of Vitriol did not crackle, and scarce burn: though a little it did: the pure coagulated Serum did not burn at all, yet crackled like decrepitating Salt, a little: that with the spirit of Vitriol and Lixivium of Nitre, did burn with a vivid and lasting flame a long time. I think myself obliged to add one thing more where I speak as if Dr. Willis had had little to do in the discoveries of Dr. Lower about Anatomy: that although that great Physician had not leisure to attend the Anatomical Inquiries, yet did he propose new matter for improving the discoveries, and put Dr. Lower upon continual investigation, thereby to see if Nature and his Suppositions did accord: and although that many things did occur beyond his apprehension, yet was the grand occasion of that work, and in much the Author. This Intelligence doth not cross what I related before from good testimony; yet I thought myself obliged to declare the whole truth, and such I believe this to be. I must also profess that I think the Sinus venarum vertebrales, whose invention I ascribe to Dr. Lower, may without considerable injury be ascribed unto Fallopius in his Anatomical Observations pag. 193. edit. Coloniens. 1562. in 80. Thus much I thought fitting to annex, lest the Virtuosos should censure me as partial to my old School-fellow Dr. Lower, or swayed by any regard then that of Truth. The Hogs-blood which I last mentioned as poured upon the Mothers of Saltpetre; after it had stood above three weeks unmixed, did at last cast down about half of itself below the Mothers, it continuing in that place it turned crimson: that on the top did not change its colour, but on the surface there gathered a crust or mass, not very thick (as before) nor of so solid a coasistence. FINIS. To divert my Reader after so tedious a discourse, I shall here add the Letter of Coga their Patient, that they may see how efficacious the Transfusion hath been on him, and what returns he makes for his Cure. To the Royal Society the VIRTUOSOS, and all the Honourable Members of it, the Humble Address of AGNUS COGA. YOur Creature (for he was his own man till your Experiment transformed him into another species) amongst those many alterations he finds in his condition, which he thinks himself obliged to represent them, finds a decay in his purse as well as his body, and to recruit his spirits is forced to forfeit his nerves, for so is money as well in peace as war. 'Tis very miserable, that the want of natural heat should rob him of his artificial too: But such is his case; to repair his own ruins, (yours, because made by you) he pawns his clothes, and dearly purchases your sheep's blood with the loss of his own wool. In this sheepwracked vessel of his, like that of Argos, he addresses himself to you for the Golden Fleece. For he thinks it requisite to your Honours, as perfect Metaplasts, to transform him without as well as within. If you oblige him in this, he hath more blood still at your service, provided it may be his own, that it may be the nobler sacrifice. The meanest of your Flock, AGNUS COGA.
