easily answered, That yet it cannot keep it from squeezing on all sides, and pressing out the milky and serose humour in the Butter, if there were any such pressure, as is supposed. To which you may further adde, That the Lump of Butter being reduced to the figure, suppose, of a round Trencher, whose edge should fall short of the Area of the two sides an hundred or two hundred times, and then placed betwixt two thin light Trenchers broad enough for the purpose, and hung free in the Aire with strings, as in a Scale, so that the force of pressure from above and beneath shall exceed that against the round edge of the Butter an hundred or two hundred times, yet the Butter will not for all this be pressed closer by the Spring of the Aire, nor have any more effect upon it then it had before: when notwithstanding it is so soft and yielding, that a very small force of our hands will press it betwixt the two Trenchers.
12. Which yet is not, because our strength is superadded to the force of the Spring of the Aire: For the excess of the force of the Spring of the Aire against the sides of the Trenchers above that which is against the round edge of the Butter, is far greater then the addition of the force of our pressing hand added to the force of the Aire-spring against the sides of the Trencher, and yet there was no new effect.
And moreover where this Aire-spring does not reach, namely, within the sides of a paile filled with water, in which you may put a lump of Butter, the Butter will there as easily yield to the pressure of your hand as in the Aire it self. So that it is irrefragably evident, that there is no such Spring of the Aire as some learned men have supposed, much less so strong as to master an hundred pound weight, as it is conceived to doe in this notable Experiment of the Aire-pump.
13. But as the Phænomenon of Gravity is quite cross and contrary to the very first Mechanick laws of Motion, which yet is an Universal law of Terrestrial bodies, put upon them by that which is not onely not Terrestrial, but Immaterial: so likewise this ascending of the Sucker of the Aire-pump with above an hundred pound weight at it, is as cross and violent a breach of that Universal Law of Gravity, and so forcible, that it is apparent, that there is a Principle transcending the nature and power of Matter that it does umpire and rule all, that directs the Motion of every part and parcell of Matter backwards and forwards and contrary waies, in pursuance of such General designs as are best for the Whole. And no less good then the living and breathing of Animals is aimed at in this so industriously and peremptorily keeping the parts of the Aire together, as is well observed by this vertuous and judicious Authour, upon his 41 Experiment.
Wherefore it being so manifest, that there is a Principle in the World that does tug so stoutly and resolutely against the Mechanick laws of Matter, and that so forcibly Resists or nulls one common Law of Nature for the more seasonable exercise of another, this, I say, is a very sure pledge to us, that when things are fitly done, though not with this seeming violence and peremptoriness, yet they are the Effects of the same Immaterial Principle, (call it the Spirit of Nature or what you will) which is the Vicarious Power of God upon this great Automaton, the World.
