a mans breath might produce in an heavie bullet ly ing upon an 

 even 3 inrcl,& flipery plain, (for a table would be too (hortjas he 

 did,how admirable great a one it produced in pendants hanging 

 in the aire : and, I doubt not but he \vould have granted it as 

 powcrfirll in ca tiling horizontall motions, as he found it in the 

 undulations of his pendants. Which nevertheleflc, do fiifficiently 

 convince how great a power airc hath over heavie bodies. As 

 likewise the experience of wind-guns aflurtth us that aire duly 

 applied is able to give greater motion unto heavy bodies then 

 unto light ones. For how can a ftraw or feather be imagined 

 poffibly to fly with half the violence as a bullet of lead doth out 

 of one of diofe engines ? And when a man fucketh a bullet up- 

 wards in a perfectly bored barrell of a gun, which the ballet 

 fitccth exactly fas we have mentioned before) with what a vio- 

 lence doth it follow the breach and afcend to the mouth of the 

 barrell ? I remember to have feen a man that was uncautious 

 ond fucked ftrongly that had his foreteeth beaten out by the 

 blow ofthebullcc afcending. 



This cxperimeat(if well looked intojmay perad venture make 

 gocd a great part of this doctrine we now deliver. For,the aire 

 prefling in behind the bullet at the touch-hole, giveth it its im- 

 pulfc upwards; unto which the denfity of the bullet being added, 

 you have the caufe of its fwiftncs and violence; (for a bullet of 

 wood or cork,would not afcend fb faft and fo ftrongly) and the 

 fucking away of the aire before it, taketh away that refiftancc 

 which otherwife it would encounter with by the aire lying in the 

 way of ic: & its following the breath with fogreat eafe,mcwetfe 

 (as we touched bcfore)that of it felfitis indifferent to any moti- 

 on,when nothing prefleth upon it to determine it a certain way. 

 _ Now to Galileos laft argument j that an arrow fliould fly 



An anfwer to fader broadvvaycs, then longwayes, if the airc were caufe of its 

 ftion hir ?-t J 9 C n motionrthcreneedcth no mote to be faid, but that the rcfiftance 

 arrow fliould of the airc before, hindreth has much as the impulfe of the airc 

 behind helpeth it on ; fo tlia: nothing is gained in that regard ; 

 but much is lofr, in refpe^l ofthe figure which makcth the ar- 

 row unapt to cut the airc fo well when it flyeth broad waycs, as 

 when it is fhot longwayes : and therefore the aire being weakly 

 cut, fo much of it cannot clap in behind the arrow and drive it 

 on, againft the refinance beforc.which is much greater.
