Also, some may say, If there be Pores in Nature, there may be Vacuum.
I answer, That, in my opinion, there is not; because there is no empty Pores in Nature: Pores signifying only an Egress and Regress of Parts.
[CHAP. XII. Fire hath not the Property to Change and Rechange.]
Of all the Elemental Creatures, Fire is the least subject to change: for, though it be apt to occasion other Creatures to alter; yet it keeps close to its own Properties, and proper Actions: for, it cannot change, and rechange, as Water can. Also, Natural Air is not apt to change and rechange, as Water: for, though it can (as all the Elements) divide and join its Parts, without altering the Property of its Nature: yet, it cannot readily alter, and alter again, its Natural Properties, as Water can. The truth is, Water and Fire, are opposite in all their Properties: but, as Fire is, of all the Elements, the furthest from altering: so Water is, of all the Elements, the most subject to alter: for, all Circular Figures are apt to variety.
[CHAP. XIII. Of the Innate Figurative Motions of Water.]
The Nature of Water is, Rare, Fluid, Moist, Liquid, Wet, Glutinous, and Glassie. Likewise, Water is apt to divide and unite its Parts, most of which Properties are caused by several sorts of Dilatations, or Extenuations: but, the Interior, or Innate Figure of Water, is a Circular Line. But yet, it is to be observed, That there are many several sorts of Waters, as there are many several sorts of Airs, Fires, and Earths, and so of all Creatures: for, some Waters are more rare than others, some more leight, and some more heavy; some more clear, and some more dull; some salt, some sharp; some bitter, some more fresh, or sweet; some have cold Effects, some hot Effects: all which is caused by the several Figurative Motions of several sorts of Waters: but, the nature of Water is such, as it can easily alter, or change, and rechange, and yet keep its Interior, or Innate Nature or Figure. But this is also to be observed, That the Dilating or Extenuating Circle of Water, is of a middle Degree, as between Two Extreams.
