« 5 Y atiirall Hijtorj: 
haue gotten a Pretty Exprefiion, by a Word of Art, tha lExprejjion goeth 
currant ; though it bee empty of Matter. This Conceit of Elifion, appea- 
re di molt manifeftly to bee falfe, in that the Sound ofa Bell, firing, or the 
like, continueth melting, Tome time, after the Per cuff on j Buteeafeth 
ftreight-waves, if the Boll, or String , be touched and Itayed; whereas,ifit 
were the Elifion of the Aire, that made the Sound* it could not bee, that 
the T ouch of the Bell, or String, fhould extinguifh fo fudden ly that Mo¬ 
tion, caufed by the Elifion of the Aire, This appeareth yet more mani- 
fcftly, by Chiming with a Hammer, Ivpon the Out -fide ofa Bell 5 For the 
Sound Will be according to the inward Concaue ofthe Bell • whereas the 
Elifion, or Attenuation of the Aire, cannot bee but onely betweene the 
Hammer^ and the Out-fide of the Bell. Soagaine, if it were an Elifion, a 
broad Hammer, and a Bodkin, ftrucke vponMetall, would giue a diners 
Tone - As well as a diners Loudneffe : But they doe not lb 5 For though 
the Sound of the one bee Lender, and of the other Softer, yet the Tone is 
the fame. Belides, in Ecchds, (whereof fome are as loud as the Original 
Voite,) there is no new Elifion • but a Repercuffion onely. But that which 
conn i nee th it mod of all, is, that Sounds are generated, where there is no 
Aire at all. But thefe and the like Conceits,when Men hauecleared their 
vnderftandmg, by the light of Experience, willfcatter, and breake vp 
likeaMift. 
It isccrtaine, that Seundis not produced at the firft, butwith fome' 
Lee all CMotion of the Aire, or Flame,* or fome other Medium^ Nor yet with¬ 
out fome Refifiance, either iu the Aire, or the Body Per cuffed. For if there! 
bee a meere Yeeldmg, or Ceifion, it produceth no Sound • As hathbeene 
faid. And therein Sounds differ from Light, and Colours ; which pafte 
thorow the Aire, or other Bodies, without any Locall Motion of the Aire ‘ 
either at th« firft. or after. But you miift attentiuely diftinguifli, be- 
tweene the Locall Motion of the Aire, (which is butVehiculum Cauff<t, A 
Carrier of the Sounds,) and the Sounds themfelues, Conueighed in the 
Aire. For as to the former, wee fee manifeftly, that no Sound is produ¬ 
ced (no not by Aire it fclfe againft other Aire, as in Organs, See.) but with 
a perceptible Blafi of the Aire • And with fome Refifiance of the Airt-j 
ftrucken. For eucn all Speech , (which is one of the gentleft Motions of 
Aire,) is with exptilfion ofa little Breath. And all Pipes haue a Blaft, 
as wcllas a Sound. Wee fee alio manifeftly, that Sounds are carried With 
W'inde: And therefore Sounds will bee heard further with the ivinde, than 
againft: the winde • And like wife doe rife and fall with the Intcnfion or 
Remiflion of the Winde. But for the lmprefiion of the Sound , it is qu ite ano¬ 
ther Thing • Andisvtterly without any Locall Motion of the Aire , Per¬ 
ceptible 5 And in that refembleth the Species viable : For after a Man 
hath lured, or a Bell is rung, wee cannot difeerneany Perceptible Motion 
(atall)in the Aire, as long as the Sound goeth 5 but onely at the firft. Nei¬ 
ther doth the Wind (as farre as it carrieth a Voice,) with the Motion thereof, 
confound any of the Delicate, and Afticulate Figurations of th e. Aires, 
in Variety of Words. And if a Man fpeake a good loudneffe, againft
