Njiturall Hi/lory 



ligbtfpme or dark, hot or cold, quiet or ftirring, (except it be With Noife) 

 fweet-fmelling, or (Unking, or the like 3 it iroporteth not much: Some 

 pet^, AlteratiQnoridifference it may make. 



£ut Sounds do difturb and alter the one the other : Sometimes the one 

 mit^f&ki other ,3nd making it not heard \ Seme times the one jarring and 

 difcording with the other, and making a Confufion 5 Sometimes the one 

 Mingling and Compounding with the other ,and making an Harmony. 



Two Voices of like lowdnefs', will not be heard, twice as farre, as one of 

 them alone ; And two Candles of like light, will jiot make things feem 

 twice asfarre off,as one. The Caufe is profound But it feemeth that the 

 Imfnflions from the oh]eUs of the Senjes, do mingle refpe&ively, every one 

 with his kind But not in proportion, as is before demonftrated: And the 

 reafon may be,becaufe the firft Imfredion^YAch. is from Privative to Aclive 

 (As from Silence to Noife, or from Darknefl to Light,) is-a greater Degree, 

 than from Lefs Noife, to Mere Noife ,or from Ltfs Light to More Light. And 

 the Reafon of that again may be - 7 For that the Air , after it hath received a 

 Charge, doth not recive a Surcharge, or greater Charge, with like Appe- 

 tite, as it doth the firft Charge. As for the Encreafe of Vertue generally, 

 what Proportion it beareth to the Encreafe of the Matter, it is a large Field, 

 and tp be handled by it felf. 



ALL Reflexions Concurrent, do make Sounds Greater •, But if the Body 

 that createth, either the Originall Sound, or the Reflexion, be clean and 

 fmootryt jnaketh them Sweeter. Triall may be made or a Lute,or Violl,mt\\ 

 the Belly ; of poliihed Brafs in Head of Wood. We fee that even in the O- 

 pen Air, the wire String is fweeter,than the String of Guts, A nd we fee that 

 for Reflexion, Water excelleth-,As in Muflick near the JYater;Ot in Lcchos. 



It hath been -tried, that a fife a little moiftned on the infide, but yet fo as 

 there be no Drops left, maketh a more folemn Sound, than if the Pipe were 

 dry £ But yet with a fweet Degree of Sibilation, or Purling As we touched 

 it before in the title of Equality. The Caufe is, for that all Things Porous, 

 being fuperficially wet, and(as it were) between diy and wet, become a lit- 

 tle more Even and Smooth •, But the Purling (which muft needs proceed 

 of Inequality,) I take to be bred between the Smoothnefs of the inward 

 Surface of the Pipe, which is wet And the Rett of the Wood of the Pipe, 

 unto which the Wet cometh not, but it remained dry. 



Jn Frofly Weather, Mufick within doors foundeth better . W'hich may be, 

 by reafon, not of the Difpofition of the Air, but of the Wood or String of 

 the Inflrnment, which is made more Crifpe, and fo more porous aud hol- 

 low And we fee that old Lutes found better than Nevefot the fame reafon. 

 And fo do Lute- firings that have been kept long, 



Sound as likewife Meliorated by the Mingling of Open Air with Pent Air } 

 Therefore Triall may be made, of a Lute or Vtoll with a double Belly • Ma- 

 king another Belly with a Knot over the Strings % yet fo, as there be Room 

 enough for the Strings, and Room enough to play below that Belly. Triall 

 may be alfo of an Irijh Harp, with a Concave on both Sides •, whereas it 

 ufeth to have it but on one Side. The doubt may be, left k mould make too 

 much Refounding-, whereby one Note would overtake another. 



If you ling in the Hole of a Drumjt maketh the Singing more fweet. And 

 fo I conceive it would, if it were a Song in Parts, fung into feverall Drums jj 

 And for handforanefs and ftrangenefs fake, it would not be amifstohave 

 a Curtain between the Place, where the Drums are, and the Hearers.
