sides The Nucleus or Ball in the middle of the head which I have called the Star I conceive to be dissolved equally on all sides and the parts which are dissolved or separated from it I conceive to fly every way from the center of it with pretty near equal celerity or power like so many blazing Granadoes or Fire-balls these continue their motion so far toward the way they are shot till the Levitation from the body of the Sun deflect them upwards or in opposition to the Sun into a Parabolick curve in which Parabolick curve every single particle continues its motion till it be wholly burnt out or dissolved into the Aether These are continually succeeded by new separations from the aforesaid body in the same manner as t is observable in a burning steaming or smoaking body in our air or a dissolving body incompassed with its proper menstruum as I before mentioned and will so continue until the whole be at length dissolved into the Aether through which it passes It hath been demonstrated by Torricellius of bullets or other bodies cast or shot upwards that the same or equal bullets discharged or shot out from the same point with the same degree of strength but with differing degrees of inclination to the Horizon each of them shall be moved in a parabolical line and every one of those parabolical lines shall touch a parabolical line whose axis is the perpendicular and whose apex is distant from the said point the full altitude of the perpendicular shot So that supposing in the twenty second figure A to be the point from whence all the shots are made with equal velocity AC the greatest height of the perpendicular shot and AD the greatest Horizontal random at 45 degrees of inclination and suppose EDCDE a parabola passing through those points DCD all the shots made with equal bullets with equal velocity from A but with all variety of inclination between the perpendicular upwards and the perpendicular downwards that touch the said parabolical line and consequently if there be an indefinite number of such balls continually flowing out of the point A with equal degrees of celerity every way dispersing themselves equally in orbem the whole aggregate of such an emanation will make a solid parabolical conoeid EDCDE Now about the point A if we suppose a Sphere as BBBB and from this Sphere an indefinite number of such equal Balls be thrown off perpendicularly to the superficies of it from every point thereof with equal celerity at their leaving it those emanations will form also a conoeid which will be very near the same with the former And if this Ball in the middle be supposed a burning and shining body and that all these emanations have every one of them equal light in proportion to the Globe BBBBA the effect produced hereby will perfectly resemble the appearance and figure of Comets if at least the Parabolical conoeid be inverted which will somewhat explain the manner how I conceive the figure of the Cometical body is naturally and most proportionably formed for if the effect of such an emanation of shining bodies be examined it will very plainly exhibit the exact and true apparent figure of Comets as they may be seen through a good Telescope which is to me a very great argument that 't is the genuine cause of its shape and figure Now though the Comets appearance be this way caused and so a man might conceive the Globous body would in a little time by so copious an emanation be consumed yet I do not believe that it doth in a short time wast and disperse the whole Ball nor can I conceive that the disappearing of those blazing bodies toward the latter end does depend upon their dissolution though possibly that may somewhat diminish them but that rather is to be ascribed to their distance and position in respect of us Though this I remember I observed very manifestly in that of 1664. that the body toward the latter end of its appearing was very much less in proportion to the radiations about it than it seemed to be at the beginning but whether that might not be partly ascribed to the great distance it then was from us and the turning of the head pretty near towards us and thence the spreading of the Tail appearing beyond it might add to the breadth of the radiation about the Nucleus I will not positively determine Now though for explication sake I have compared the parts separated from the body of the Comet to blazing Granadoes or Fire-balls yet I would not be understood to suppose these parts so separated to be of any very large bulk for I see no necessity to suppose them bigger than the Atoms of smoke or the particles of any other steaming body or than the parts of the Air which make the body of it appear thick and hazy nor do I believe that all the light of the Star head and blaze does depend only upon the shining of the dissolving body and particles thereof but I do suppose that it doth proceed both from the reflection of the Sun-beams from those parts and also from an innate and momentaneous light produced by the action of dissolution wrought on the parts by the incompassing Aether It may possibly seem very difficult to suppose that the dissolution of the parts of the Nucleus by the incompassing Aether should cause or impress so violent a motion into the separated parts as to make them depart from it to the space of four or five Diameters before it be over-powered by the power of Levitation from the body of the Sun and so deflected into a parabolical line upwards It may likewise seem strange to suppose that the Aether should have such power in it as first to dissolve a body into it self and secondly to cause a shining and thirdly to cause a Levitation of the dissolved parts upwards whereas I supposed before and I think 't is very manifest that they cause a gravitation downwards towards the Center of the Sun But to these for explication I answer that we need not go far for instances to make these things probable the Atmosphere about the Earth as I have formerly mentioned in my Micrographia I take to be nothing else but the dissolution of the parts of the Earth into the incompassing Aether for the proof of which I could bring many arguments were it here a proper place by which I could most evidently demonstrate the thing to be as I have asserted It is here evident that this Aether doth take up the particles of bodies to a very great distance from the surface from which they were separated and it doth not only raise them but susteins them at those heights nor is this peculiar only to the Aether when a menstruum but to all dissolving menstruums in general As to give one instance in stead of many we find that Gold the heaviest of all Terrestrial bodies we yet know being dissolved by Aqua Regis
