Thunder and Lightning Flame and Report of a P eece Motion of the 

 Aire in Hewing of Wood. All which have been fet down heretofore 

 but are proper for this Title. 



I conceive alfo, that the Species of A udibles, do hang longer in the Air 

 than thofe of Vifibles : For although even thofe of Vifibles, dohangfome 

 time, as we fee in Rings turned, that fhew li ke Spheres ; In Lute-firings fil- 

 lipped - 7 A Fire-brand carried along, which leaveth a Train of Light be- 

 hind it; and in the Twilight; And the like : Yet I conceive that Sounds ^ 

 ftay longer, becaufe they are carried up and down with the Wind ; And 

 becaufe of the Diftance of the Time, in Ordnance difcharged, and heard 

 wenty Miles off. 



In Vifibles ,there are not found Obje&s fo odious and ingrate to the Senfe, 

 as in Audibles. For foul Sights do rather difpleafe, in that they excite the 

 Memory of foul Things, than in the immediate Objecls. And therefore 

 in Pictures, thofe foul Sights do not. much offend; But in Audibles, the 

 Grating of a Saw, when it is marpned, doth offend fo much, as it fetteth 

 the Teeth on Edge ; And any of the harjh Dij cords in Mufick, the Ear doth 

 ftraightvvaies refufe. 



In Vifibles, after great Light, if you come fuddenly into the Bark; Or 

 contranwife, out of the Bark into a Glaring light, The Eie is dazled for a 

 time, and the Sight confufed But whether any fuch Effecl: be after great 

 Sounds, or after a deeper Silenccmzybe better enquired.lt is an old Tradition, 

 that thofe that dwell near the Cataracts of Nilus, are ffrucken deaf: But 

 we find no fuch erfecl:, in Cannoniers, nor Millers, nor thofe that dwell up- 

 on Bridges. 



It feemeth that the Imprefjion of Colour is fo weak, as it worketh not but 

 by a Cone of Direct Beames, or Right Lines whereof the Bafis is in the Ob- 

 ject, and the Verticall Point in the Eie So as there is a Corradiation and 

 Conjunction of Beames; And thofe Beames fo fent forth, yet are not of any 

 force to beget the like borrowed or fecond Beames^ except it be by Reflexion, 

 whereof we fpeak not. For the Beames pafs, and give little Tin&ure to that 

 Air, which is Adjacent*, which if they did, we liiould fee Colours out of a 

 Right line. But as this in Co lours, fo otherwife it is in the Body of Light. 

 For when there is a Skreen between the Candle and the Eie, yet the Light 

 palfeth to the Paper whereon one writeth So that the Light is fee n where 

 the Body of the Flame is not feen And where any Colour (if it were placed | 

 where the Body of the Flame is) would not be feen. I judge that Sounds of 

 this Latter Nature : For when two are placed on both fides of a Wall, and I 

 the Voice is heard, I judge it is not only the Originall Sounh, which paffeth ' 

 in an Arched Line ; But the Sound, which paffeth above the Wall in a Right ' 

 Line, begetteth the like Motion round about it, as the firft did, though 

 more weak. 



%. LL Concords and Bifcords of Mufick, 

 i\ Antipathies of Sounds. Andfo (likewifi 



(no doubt) Sympathies and j Experiments 

 Antipathies ot Sounds. And fo (likewife) in that Mufic k^which we call j in Conforc 

 Broken Mufick, ot Con fort Mufick ; Some Conforts ollnftruments are fweeter j gj*|jg 

 than others •, (A Thing not fufficiently yet obferved:) As the irijh Harp, ' Antipathy of 

 and Bafe Viall agree well : The Recorder and Stringed Mufick agree well: Or- j ^- ° ^ 

 gans and the Voice agree well, &c. But the Virginalls and the Lute ; Or the | Wlt 

 Welch-Harp t, and Irijh- H arp ; Or t\\z Voice and Pipes alone, agree notfo 

 well But for the Melioration of Mufick there is yet much left (in this Point j 

 of Exquifite Conforts) to try and enquire.
