ther like Inftances, whereof we lliall fpeake more, when wee handle the 
Communication of Sounds. 
It were extreme GroffendTeto thinke (as wee hauepartly touched 
before) that the Sound in Stringsis made, or produced, betweene the 
Hand and the Strings or the guill and the String, or the Bow and the 
String : Fprtholc are but Vehtcula Mot us, Pajfager to the Creation o£ die 
Sound \ the Sound being produced betweene the String and the Aire ; 
And that not by any Impulsion of the Aire, from the 6 rll Motion of the 
String • butby the Returne or Rcjult of the String , which was {trained by 
the Touch, to his former Place : which Motion of Refuli is qiiicke and 
fharpe 5 Whereas the firft Motion, isfoftanddull. Sothe-ffwtortureth 
the String continually, and thereby hoideth it in a Gondntull Trepi¬ 
dation. 
T Ake a Trunke, and let one whittle at the one End, and hold your 
Eare at the other, and you thall finde the Sound ftrike fo fharpe, as 
you can fcarce endure it. The Cau/e is; for that Sound dilfufeth it felfe in 
round • And fo fpendeth.it lelfe j But if the Sounder hich would fcarterin 
Open Abe, bee made to goc all into a Canale; 1 1 mtift needs giue gredter 
force to the Sound. And fo you may note, that Enclofures doe net only pre- 
feme Sound, but alfo Encreafe and Sharpen it. 
A Hunters Heme, being greater at one end, than at the other, dothin- 
creafe the sound more, than i f the Horne were all of an equal! Bore. The 
Canfe is, for that the Aire, and Sound^ being firii contracted at the Idler 
end, and afterwards hauing more Roome to fpread at the greater cndjdoe 
dilate thcmfdues 5 And in Comming out ftrike more Aire ; whereby the 
Sound is the Gteater,and Baler. And euen Hunters Hornet, which are fome- 
times made ftreight, and not Oblique, are euer greater at the lower end, 
1 1 would be tried alio in Pipes, being made far larger at the lower end: Or 
being made with a Belly towards the lower End * And then illuing into A 
ftreight Ooncaue agairic. 
There is in Saint fames fields,aConduit of Brtrice, vnto which ioyneth a 
low Vault ; And at the End of that, a Round Honfe of Stone: And in the 
Bricke Conduit there is a Window j And inthc Round Honfe a Slit or Rift 
offome little breadth.Tfyoucfy out in the Rift, it will make a featfollRoa- 
ring at the Window. The Caufie is the lame with the former 5 For thatajl

Hawkes Belli, that haue Holes in the Sides, giue a greater Ring, than 
if the Pellet did ftrike vpon BralFe, inthc Open Aire. The Caufe is the 
fame with the firft infiance of the Trunke 3 Namely, for that the Sound 
Enclofed with the Sides of the Belf commeth fotth at the Holes vnlpenf,' 
and more ftrong.
