Chip. ii. 4 Trcttifttf BODIES. 



fuch atomes, thefe \vc fpeak of, muft be in them, an.! in 

 pn-rt of them, and every where paffe through and through 

 them as water doth throifgh a feive or through a fpungc : and 

 tins univerlall maxime muft extend as hrre as the funnc, or as 

 any other heat communicating with thcfunnc > <ioch reach and 

 is Found. 



The rcafon -whereof is, becaufc thefc atomes arc no other 

 thing, but fuch extreme little bodies as are refolvcd by heat; 

 out of the main ftock of tlx>fc ma flic bodies upon which t'he fun 

 and heat <3o "work. Now then bffing certain, out o r whst we 

 hare heretofore faid, that all mirt bodies have their temper and 

 cofifarence, and generation from the mingling of fire with the 

 irft -of the Elements that compote them ; and from the cor- 

 co&ion or digeftion winch fire matath in thole bodies : it is e- 

 vident, that no mixt body whatfocveT J nor any fenfible part of 

 a mm body, can be yoid of pores capable of fuch atotnes, nor 

 can be without fuch atomes, paiTing th rough thofe pores; whidh 

 atomes by mediation of thcake (that likewise hath its ifoarc ht 

 fuch pores) muffi have comrmffrication with the reft of t'he great 

 fea of aire, and with the motions that pafTe in it. A/nd -con'fe- 

 quently, in all and crery fcnfibk pact, of any ftjch extreme 

 drn(e, and prctertded knpenetra'blc body, (to the notice whereof 

 we can arrive)this percuffion of atornes muft be found; and <4iey 

 will have no difficulty in running throogh ; nor by means of it, 

 in (triking any other body lying under the fhelter of it;and thus 

 both in&fromjthathard body,thcremuft be (till an uninterrupt- 

 ed continuation of gravity or of defending towards the center. 



Unto which we may adde, that the ftone or denfe body can- 

 not lie fo clofe to the reck that covereth it, but that fome aire 

 maft be between, (for if nothing were between, they would be 

 united,and become one continued body ;)and in that airef which 

 is a creek of the great ocean of aire fpred over tltc world, that is 

 every where beftrcwed with moving atomes; and which is con- 

 tinually fed, like a rtirmtngftrcam, with new aire that drivetk 

 on the aire it orertaketh)there is Hodoubtbnt there arc dcfcend- 

 jngatomes, as well as in all the red ofits main body : and thefe 

 descending atomes meeting with the ftone, muft tjeecls^ive fbme

 but work fome effcft, in niaiving the ftone remove a little that
