The Experiment for greateil Demomlration oF Communication of J 
Sounds is the Chiming of Bells • Where if you ftrike with a Hammer vp- 
onthe Vpper Part, and then vpon the Midft, and then vpon the Lower, 
you fhall hnde the Sound to bee more Treble, and more Bafe, according 
vnto the Concaue, on the Infide • though the Perculfion bee onely on the 
Out-fide. 
When these find is created berweenethe Elafi of the Mouth, and the 
-Aire of the Pipe, it hath neuerthelelfe fome Communication with the Mat¬ 
ter of the Sides of the Pipe, and the Spirits in them contained ; for in a 
Pipe or mw/^,ofWood,and Bralfe,the^V#»^ will bee diners • So if the 
Pipe be couered with Cloth, or Silkc, it will giue a diuers Sound, from that 
it would doe of it felfe • So, if the Pipe bee a little wet on the Infide, it will 
make a differing Sound, from the fame Pipe dry. 
That Sound made within Water, doth communicate better with a 
hard Body thorow water, than made in Aire^>, it doth with Aire ; Vtde^r 
Exptrimentum 134. 
Wee haue fpoken before (in the Inquifition touching Mu - 
ficke,) of MuficallSounds, whcrcunto there may be a Concord 
or Difcord in two Parts; Which Sounds wc call Tones: And 
like wife of lmmuficall Sounds ; And haue giuen the Caufe, chat 
ch cfyne proceeded) of Equality, and the otherof Inequality; 
And wee haue alio exprefled there, what arc the EquallBodies 
that giucTones, and what arc the VnequaG that giue none. But 
now wee (hall fpeakc of futh Inequality of Sounds, ns*pro‘ccc» 
deth, notiromthc Nature of the Bodies thcmfelucs, but is Ac- 
cidcntall j Either from the Rougbnejfe, oxObliquitie of the 1 ?*/- 
[age j Or from the Doubling of the Percutient ,Ot from the Tre- 
pidation of the Motion. 
A M,iftt haue a Rift in it,Whereby the Sound hath not a cleare Palfage, 
giueth a Hoarfea nd Urrtng Sounders the Voice of Man; when by cold taken 
the Wefi 11 groweth rugged,and(as wecaIlit)furred,becomrneth hoarfe, j 
^nd in thefe two inflancts,the Sounds arc Ingrate; becaufc they are nicer- j 
lv vnequall: But, ifthey bee VneqUall in Equality, then the sound is Grate- 
full, but Purling. 
All Infir umtnts, that haue either Re tames, as Trumpets • Or Flexions, 
as Cornets ; Or are Drawnevp, and/wf/*tfW, as Sackburs; haue a Purling j 
Sound: But the Recorder os Flute, that haue none of thefe Inequalities, giue 
a cleare Sound. Neuerthelelfe, the Recorder itlelfe, or Pipe moifteneda 
little in the Infide, foundeth more folemnlv, and with a little Purling, of 
Hilling. Againe,a wreathed S/rag,{uchasare in the Bafe Strings of B&n- 
doraes , giueth alio a Purling Sound. 
But a Lute-firing, if it be inecrely VneqUalli n his Parts, giueth a Harfh
