$45 folutc Plenitude therein. For, doubdefs, were all thofe fubde Effluxions coadunated into one denfe and folid mafs ^ it would not arife to a magni¬ tude equal fo much as to the io^‘\ nay the 40^'^ part of the capacity aban¬ doned by the dclapfed Mercury. But fill it to that proportion, as to leave only a Vacuitj Diffemimte: fuch as is introduced into an afiolipile, when by the Atoms of fire entered into, and varioufly difeurrent through its Concavity, the infenfible Particles of Aer and Water therein contained, are reduced to a more lax and open order, and fo the inane Incontiouities betwixt them ampliated. And this we judge fufficient concerning The fo- lution of the Firfi Difficulty. Sect. III. WJiat is the immediate Remora or Impediment, wherebphe \^er, which in refpeB of the natural Confiuxihility of its infenfible par^ tides, foftrongly and expeditely praventeth any exceffive vacuity, in all other ted. ^ ^ cafes, is forced to pfffer it in this of the Experiment ? The Solution. Infomuch as the Fluidity, or Confluxibility of the Atomical or infenfible Art.i, particles of the Aer, is the proxime and foie Caufe of Natures abhorrence of all fenfible Vacuity 5 as hath been proved in the prsecedent Section: Jhecreanolfof Manifcft it is, that whofoever will admit a Vacuity exceffive, oragainft ancxceirive, the rite of Nature, muft, in order to the introduftion or Creation thereof, admit alfo two diftind Bodies •, <1; One, which being moved out of its place, muft propel the contiguous aer forward, {i) Another, which in- terpofed, muft hinder the parts of the circumftant aer, propulfcd by the parts of the aer Impelled by the firft movent, from obeying the Confluxi. bility of their Figure, and fucceeding into the place deferted by the body firft moved. Which is the very fcope, that the profound GaliUo propofed to himfelf, > when He invented a wooden Cylindre, as an Embolus or Sucker to be in. The ^ocifion truded into another concave Cylindre of Brafs, impervioufly ftopped be- of GaliIdas in- low 5 that by the force of weights appended to the outward extreme, or 'Br]fs°Viindre handle thereof, the fucker might be gradually retradled from the bottom chfrged'^with of the Concave, and fo leave all that fpace, which it forfaketh, an entire ayoodenfm- and coacervate Vacuum. Upon which defign TorricelHus long after me- and of ditacing, and calling about for other means more conveniently fatis- ce^''«invenri- fadlory to the fame intention 5 Hemoft happily lighted upon the pr.^fent Experiment: wherein the Quic'kfilvcr became an accommodate fubftitutc to GaliUo's wooden fucker, and the Glafs Tube to theBrafsconcave Cylindre.$
