may have made you hot Is Motion therefore hot No. You are to consider the Concomitants of your heat as that you are more faint or more ruddy or that you sweat or feel some Endeavour of Moisture or Spirits tending outward and when you have found the Causes of those Accidents you have found the Causes of Heat which in a living Creature and specially in a Man is many times the Motion of the parts within him such as happen in sickness anger and other passions of the minde which are not in the Sun nor in Fire A. That which I desire now to know is what Motions and of what Bodies without me are the Efficient Causes of my Heat B. I shewed you yesterday in discoursing of Rain how by this compounded Motion of the Suns Body the Air was every way at once thrust off West and East so that where it was contiguous the small parts of the water were forced to rise for the avoiding of Vacuum Think then that your hand were in the place of water so exposed to the Sun Must not the Sun work upon it as it did upon the Water Though it break not the skin yet it will give to the inner Fluids and looser parts of your hand an Endeavour to get forth which will extend the skin and in some climates fetch up the bloud and in time make the skin black The Fire also will do the same to them that often sit with their naked skins too neer it Nay one may sit so neer without touching it as it shall blister or break the skin and fetch up both spirits and bloud mixt into a putrid oyly matter sooner than in a Furnace Oyl can be extracted out of a Plant. A. But if the Water be above the Fire in a Kettle what then will it do Shall the particles of water go toward the Fire as it did toward the Sun B. No. For it cannot But the Motion of the parts of the Kettle which are caused by the Fire shall dissipate the Water into Vapour till it be all cast out A. What is that you call Fire Is it a hard or Fluid Body B. It is not any other Body but that of the shining coal which coal though extinguished with Water is still the same Body So also in a very hot Furnace the hollow spaces between the shining coals though they burn that you put into them are no other Body than Air moved A. Is it not Flame B. No. For flame is nothing but a multitude of Sparks and Sparks are but the Atomes of the Fewel dissipated by the incredible swift Motion of the Movent which makes every Spark to seem a hundred times greater than it is as appears by this That when a man swings in the Air a small stick fired at one end though the Motion cannot be very swift yet the Fire will appear to the eye to be a long streight or crooked Line Therefore a great many sparks together flying upward must needs appear unto the sight as one continued Flame Nor are the sparks striken out of a Flint any thing else but small particles of the stone which by their swift Motion are made to shine But that Fire is not a substance of it self is evident enough by this that the Sun-beams passing through a Globe of Water will burn as other fire does Which beams if they were indeed Fire would be quenched in the passage A. This is so evident that I wonder so wise men as Aristotle and his followers for so long a time could hold it for an Element and one of the primary parts of the Universe But the Natural heat of a man or other living Creature whence proceedeth it Is there any thing within their Bodies that hath this compounded Motion B. At the breaking up of a Deer I have seen it plainly in his Bowels as long as they were warm And it is called the Peristaltique Motion and in the Heart of a Beast newly taken out of his Body and this Motion is called Systole and Diastole But they are both of them this compounded Motion whereof the former causeth the food to Winde up and down through the guts and the later makes the Circulation of the Blood A. What kind of Motion is the Cause of Cold Methinks it should be contrary to that which causeth Heat B. So it is in some respect For seeing the Motion that begets Heat tendeth to the separation of the parts of the Body whereon it acteth it stands with reason that the Motion which maketh Cold should be such as sets them closer together But contrary Motions are to speak properly when upon two ends of a Line two Bodies move towards each other the Effect whereof is to make them meet But each of them as to this Question is the same A. Do you think as many Philosophers have held and now hold that Cold is nothing but a privation of Heat B. No. Have you never heard the Fable of the Satyre that dwelling with a Husbandman and seeing him blow his fingers to warm them and his Pottage to cool it was so scandalized that he ran from him saying he would no longer dwell with one that could blow both Hot and Cold with one breath Yet the Cause is evident enough For the Air which had gotten a Calefactive power from his vital parts was from his mouth and throat gently diffused on his fingers and retained still that power But to cool his Pottage he streightened the passage at his lips which extinguished the Calefactive Motion A. Do you think Wind the general Cause of Cold If that were true in the greatest Winds we should have the greatest Frosts B. I mean not any of those uncertain Winds which I said were made by the Clouds but such as a Body moved in the Air makes to and against it self For it is all one Motion of the Air whether it be carried against the Body or the Body against it Such a Wind as is constant if no other be stirring from East to West made by the Earth turning dayly upon its own Centre Which is so swift as except it be kept off by some hill to kill a man as by Experience hath been found by those who have passed over great Mountains and specially over the Andies which are opposed to the East And such is the Wind which the Earth maketh in the Air by her Annual Motion which is so swift as that by the Calculation of Astronomers to go Sixty miles in a minute of an hour And therefore this must be the Motion which makes it so cold about the Poles of the Ecliptique A. Does not the Earth make the Wind as great in one part of the Ecliptique as in another B. Yes But when the Sun is in Cancer it tempers the Cold and still less and less but least of all in the Winter-Solstice where his beams are most oblique to the Superficies of the Earth A. I thought the greatest Cold had been about the Poles of the

straight line from my Eye to the Sun terminated in the East B. 'T is not due East but partly East partly South For the Earth being but a point compared to the Sun all the parallels to D E the Aequator such as are e a f b e g if they be produced will fall upon the Body of the Sun And therefore A b is North-East A a East North-East And A c North North-East A. Proceed now to the Cause of Attraction B. Suppose now that the Internal parts of the Loadstone had the same Motion with that of the Internal parts of the Sun which make the Annual Motion of the Earth from West to East but in a contrary way for otherwise the Loadstone and the Iron can never be made to meet Then set the Loadstone at a little distance from the Earth marked with z and the Iron marked with x upon the superficies of the Earth Now that which makes x rise to z can be nothing else but Air for nothing touches it but Air. And that which makes the Air to rise can be nothing but those small circles made by the parts of the Earth such as are at a b c for nothing else touches the Air. Seeing then the Motion of each point of the Loadstone is from East to West in Circles and the motion of each point of the Iron from West to East it follows that the Air between the Loadstone and the Iron shall be cast off both East and West and consequently the place left empty if the Iron did not rise up and fill it Thus you see the Cause that maketh the Loadstone and the Iron to meet A. Hitherto I assent But why they should meet when some Heterogeneous Body lyes in the Air between them I cannot imagine And yet I have seen a Knife though within the Sheath attract one end of the Needle of a Mariners Compass and have heard it will do the same though a Stone-wall were between B. Such Iron were indeed a very and vigorous Loadstone But the Cause of it is the same that causeth Fire or hot Water which have the same compounded Motion to work through a Vessel of Brass For though the Motion be altered by restraint within the Heterogeneous Body yet being continued quite through it restores it self A. What is the Cause why the Iron rub'd over by a Loadstone will receive the vertue which the Loadstone hath of drawing Iron to it B. Since the Motion that brings two Bodies to meet must have contrary ways and that the Motions of the Internal parts of the Magnet and of the Iron are contrary the rubbing of them together does not give the Iron the first Edeavour to rise but multiplies it For the Iron untouch'd will rise to a Loadstone but if touch'd it becomes a Loadstone to other Iron For when they touch a piece of Iron they pass the Loadstone over it only one way viz. from Pole to Pole not back again for that would undo what before had been done also they press it in passing to the very end of the Iron and somewhat hard So that by this pressing Motion all the small Circles about the points a b c are turned the contrary way And the halves of those small Circles made on the Arch D B will be taken away and the Poles changed so as that the North-Poles shall point South and the South Poles North as in the Figure A. But how comes it to pass that when a Loadstone hath drawn a piece of Iron you may add to it another as if they begat one another Is there the like Motion in the generation of Animals B. I have told you that Iron of it self will rise to the Loadstone Much more then will it adhere to it when it is armed with Iron and both it and the Iron have a plain Superficies For then not only the points of Contact will be many which make the coherence stronger but also the Iron wherewith it is armed is now another Loadstone differing a little which you perhaps think as Male and Female But whether this compounded Motion and confrication causeth the generation of Animals how should I know that never had so much leasure as to make any observation which might conduce to that A. My next Question is seeing you say the Loadstone or a Needle touch'd with it naturally respecteth the Poles of the Earth but that the variation of it proceedeth from some accidents in the Superficies of the Earth what are those accidents B. Suppose there be a Hill upon the Earth for example at r then the stream of the Air which was between z and x Westward coming to the Hill shall go up the Hills side and so down to the other side according to the crooked Line which I have mark'd about the Hill by points and this infallibly will turn the North-point of the Needle being on the East side more toward the East and that on the other side more towards the West than if there had been no Hill And where upon the Earth are there not Eminencies and depressions except in some wide Sea and a great way from Land A. But if that be true the Variation in the same place should be always the same For the Hills are not removed B. The Variation of the Needle at the same place is still the same but the Variation of the Variation is partly from the Motion of the Pole it self which by the Astronomers is called Motus trepidationis and partly from that that the Variation cannot be truly observ'd for the Horizontal Needle and the Inclinatory Needle incline alike but cannot incline in due quantity For whether set upon a Pin or an Axis their Inclination is hindred in the Horizontal Needle by the Pin it self If upon an Axis if the Axis be just it cannot move if slack the weight will hinder it But chiefly because the North Pole of the Earth draws away from it the North Pole of the Needle For two like Poles cannot come together And this is the cause why the Variation in one place is East and another West A. This is indeed the most probable reason why the Variation varies that ever I heard given And I should presently acknowledge that this parallel Motion of the Axis of the Earth in the Ecliptick supposed by Copernicus is the true Annual Motion of the Earth but that there is lately come forth a Book called Longitude found which makes the Magnetical Poles distant from the Poles of the Earth eight Degrees and a half B. I have the Book 'T is far from being demonstrated as you shall find if you have the patience to see it examined For wheresoever his demonstration is true the conclusion if rightly inferred will be this that the Poles of the Loadstone and the Poles of the Earth are the same And where on the contrary his demonstrations are fallacies it is because sometimes he fancieth the Lines he hath drawn not where they are sometimes because he mistakes
