some place empty to prove that a Vacuum is possible if full they say that is full which they suppose to be empty p. 56. Fuere c. There were some of them that said there remained in those coals though they seem'd extinguish'd some fiery Particles which being blow'd up by the Air upon its admission did re-kindle the rest of the mass Ibid. Nae c. In good faith they seem not so much as to have considered what they should speak as to have taken it up at all adventures Do you believe that in a kindled coal there is any part which is not a coal but fire or in a red-hot Iron there is any part that is not Iron but Fire A great City may be set on fire by one spark Now if the body of fire be different from the thing fired there can be no more parts of fire in the whole Town on fire than that one spark We see bodies of divers kinds may be set on fire by the light of the Sun as well by the Refraction as the Reflexion that is made in Burning-glasses And yet I do not believe that there is any man thinks that Particles of fire darted from the Sun can pass through the substance of a crystal Globe And in the Air between the Sun and the Globe there is no fire p. 58. When is it that we may truly say of a man that he is dead or which is the same hath expired his Soul For it has been known that some men who have been taken for dead being brought out the next day revived A. It is hard to determine the point of time in which the soul is separated from the body Proceed therefore to other Experiments p. 59. Si acus c. If a Needle excited by a Loadstone hang freely within the Receiver it will nevertheless follow the motion of the Iron which is drawn about without the Receiver So objects put within will be seen by those that are without and sounds made within will be heard without all these as well after as before the exsuction of the Air except that the sounds are somewhat more weakly heard after than before B. These are most manifest signs that the Receiver is alwayes full and that the Air cannot thence be suck'd out That the sounds thence are more weak to ones hearing is a sign of the consistence of the Air for the consistence of the Air is diametrically opposite from its motion p. 61. Quia nihil c. Because there was nothing there that the weight of the Atmosphere should do no more strong or evident Argument could be made against a Vacuum than this Experiment For if of two coherent Marbles either of them should be thrust forward that way that their surfaces lye contiguous they would easily be sever'd the neighbouring Air successively flowing into the deserted place But so to pull them asunder that at one time they should lose their whole contact is impossible the world being full For then either motion must be made from one term to another in an instant or two bodies at the same time must be in the same place to say either of which is absurd p. 62. Confitentur c. They themselves and all others confess that all Ponderation is an endeavour every way by right lines unto the Centre of the Earth and so that it is made not by the figure of a Cylinder or Column but by a Pyramide whose top is the Centre of the Earth and whose Basis is part of the surface of the Atmosphere Ibid. Conatus c. Therefore the endeavour of all the points that ponderate will be propagated to the surface of the upper Marble before it can be propagated further suppose to the Earth p. 64. Has c. These Scales he puts one upon another and draws out the Air and then are they kept so comprest and united by the gravity of the external Air that six strong men cannot pull them asunder But if at length by the use of utmost endeavour they are pluckt in sunder they make a noise equal to the report of a Musquet but as soon as ever by the Stop-cock open'd there is the least entrance given to the Air they are severed of their own accord p. 65. Sed vis c. But can the Spring which they say is in the Air confer nothing to the holding up the Marble Nothing at all For there is no endeavour of the Air to the Centre of the Earth more than to any other point in the Universe For seeing that heavy things tend from the circumference of the Atmosphere unto the Centre of the Earth and thence again to the circumference of the Atmosphere by the same reflected lines the endeavour upwards will be equal to the endeavour downwards and so destroying one another they will endeavour neither way p. 66. Non potest ergo pars BC c. Therefore the part BC that is a part of the Atmosphere placed any where within the whole cannot by reason of its greatness descend although it be heavy and therefore it cannot press or gravitate Ibid. Si possibile c. If I should deny it possible that by the art of man two furfaces of two bodies could be made so accurately fit that they should touch in all points so that there could no creable Corpuscle pass between them I do not see how they could defend their own Hypothesis or disprove our Negative assertion Ibid. Vtraque c. Both these Fancies as well that of the Weight as of the Spring or Antitupy of the Air are Dreams But if it be granted that there is a kind of Recoyling in those small hairs or slender Corpuscles of which the Air consists one may enquire whence it is that those crooked bodies settled and at quiet in that posture came to be moved into a streightness They ought if they will be esteemed Natural Phylosophers to assign some possible cause of this p. 67. Cur non c. Why cannot the water which when it was injected did compress the particles of Air be again cast out by the same particles explicating themselves A. Because when explicated they require no greater place than when comprest As in a vessel full of water wherein are many Eeles the same proportion of place receives them whether they are folded round or at length Therefore they cannot drive up the water by their Spring which is nothing else but the motion of bodies explicating themselves B. The comparison of Air to Eeles in water I suppose will be well received by our Academians p. 68. Vides c. You see how foolish a thing it is to bring for the explication of such effects Metaphorical words as the shunning of a Vacuum the ahhorrence of Nature c. which heretofore the Schools used to defend their reputation Ibid. In the Gardeners Watering-pots therefore is the water suspended because that which issues out at so small a hole is so little that it cannot diffuse it self to

small Glass not containing above a pound and a half of Water the Phaenomenon might be exhibited though the Stop-cock were open provided the Sucker were drawn nimbly down We noted too that when we began to empty the Receiver the appearances of Light were much more conspicuous than towards the latter end when little Air at a time could pass out of the Receiver We observed also that when the Sucker had not been long before well Oyl'd and instead of the great Receiver the smaller Vessel above-mention'd was emptied We observ'd I say that then upon the opening of the Stop-cock as the Air descended out of the Glass into the emptied Cylinder so at the same time there ascended out of the Cylinder into the Vessel a certain steam which seem'd to consist of very little Bubbles or other minute Corpuscles thrown up from the Oyl rarefied by the attrition it suffered in the Cylinder For at the same time that these Steams ascended into the Glass some of the same kind manifestly issued out like a little Pillar of Smoke at the Orifice of the Valve when that was occasionally opened And these Steams frequently enough presenting themselves to our view we found by exposing the Glass to a clear Light that they were wont to play up and down in it and so by their whitishness to emulate in some measure the apparition of Light For we likewise sometimes found by watchfull observation that when the Flash was great not only at the very instant the Receiver lost of its transparency by appearing full of some kind of whitish substance but that for some short time after the sides of the Glass continued somewhat opacous and seem'd to be darken'd as if some whitish Steam adher'd to the inside of them He that would render a Reason of the Phaenomenon whereof all these are not all the Circumstances must do two things whereof the one is difficult and the other little less than impossible For he must give an account not only whence the appearing whiteness proceeds but wherefore that whiteness doth sometimes appear and sometimes not For our part we freely confess our selves at a loss about rendering a Reason of the less difficult part of the Problem And though Your Lordship should ev'n press us to declare what Conjecture it was that the above recited Circumstances suggested to us we should propose the thoughts we then had no otherwise than as bare Conjectures In case then our Phaenomenon had constantly and uniformly appear'd we should have suspected it to have been produc'd after some such manner as follows First we observ'd that thought that which we saw in our Receiver seem'd to be some kind of Light yet it was indeed but a whiteness which did as hath already been noted opacate as some speak the inside of the Glass Next we consider'd that our common Air abounds with Particles or little Bodies capable to reflect the beams of Light Of this we might easily give divers proofs but we shall name but two The one that vulgar observation of the Motes that appear in multitudes swimming up and down in the Air when the Sun-beams shooting into a Room or any other shady place discover them though otherwise the Eye cannot distinguish them from the rest of the Air The other proof we will take from what we and no doubt very many others have observ'd touching the Illumination of the Air in the Night And we particularly remember that being at some distance from London one Night that the People upon a very welcome occasion testified their Joy by numerous Bon-fires though by reason of the Interposition of the Houses we could not see the Fires themselves yet we could plainly see the Air all enlighten'd over and near the City which argu'd that the lucid Beams shot upwards from the fires met in the Air with Corpuscles opacous enough to reflect them to our Eyes A third thing that we considered was That white may be produc'd without excluding otherways or denying invisible Pores in the solidest Bodies when the continuity of a Diaphanous Body happens to be interrupted by a great number of surfaces which like so many little Looking-glasses do confusedly represent a multitude of little and seemingly contiguous Images of the lucid Body We shall not insist on the explanation of this but refer You for it to what we have said in another Paper touching Colours But the Instances that seem to prove it are obvious For Water or whites of Eggs beaten to froth do lose their transparency and appear white And having out of one of our lessers Receivers carefully drawn out the Air and so order'd it that the hole by which the Water was to get in was exceeding small that the Liquor might be the more broken in its passage thorow it we observ'd with pleasure That the Neck being held under Water and the little hole newly mention'd being open'd the Water that rushed in was so broken and acquired such a multitude of new Surfaces that the Receiver seem'd to be full rather of Milk than Water We have likewise found out That by heating a lump of Crystal to a certain degree and quenching it in fair Water it would be discontinu'd by such a multitude of Cracks which created new Surfaces within it that though it would not fall asunder but retain its former shape yet it would lose its transparency and appear white Upon these Considerations My Lord and some others it seem'd not absur'd to imagine That upon the rushing of the Air out of the Receiver into the empty'd Cylinder the Air in the Receiver being suddenly and vehemently expanded the Texture of it was as suddenly alter'd and the parts made so to shift places and perhaps some of them to change postures as during their new and vehement motion and their varied situation to disturb the wonted continuity and so the Diaphaneity of the Air which as we have already noted upon its ceasing to be a transparent Body without the interposition of colour'd things must easily degenerate into white Several things there were that made this Conjecture seem the less improbable As first That the whiteness always appear'd greater when the exsuction began to be made whilst there was store of Air in the Receiver than when the Air was in great part drawn out And next That having exhausted the Receiver and apply'd to the hole in the Stop-cock a large bubble of clear Glass in such a manner that we could at pleasure let the Air pass out at the small Glass into the great one and easily fill the small one with Air again We observ'd with pleasure That upon the opening the passage betwixt the two Glasses the Air in the smaller having so much room in the greater to receive it the Dissilition of that Air was so great that the small Viol seem'd to be full of Milk and this Experiment we repeated several times To which we may add That having provided a small Receiver whose upper Orifice was so narrow that
