BUc to proceed with the reft of the fenfes : becaufe nature 

 faw that fome things came fuddenlyupon a living crea- Ofth/fcnfeof 

 cure ; which might do it hurt , if they were not perceived hearing / and 

 afar off: and diat other things were placed at diftance from it, *& found is ' 

 which would greatly helpe it, if it could come necre unto them ; 

 fhe found a meanes to give us two fenfes more, for the di/covery 

 of remote things. The one principally and particularly to defcfry 

 their mocion. The other to marke their bulke and Situation. 



And fb to begin with the former of thefe ; we muft needs ac- 

 knowledge (after due examination of the matter)that che thing 

 which we call found is purely motion. And ific be objected that 

 many motions are made without any difcernabte found: We 

 ftiall not make difficulty to grant it 5 considering that many 

 motions die, before they come to touch the eare , or elfe are fb 

 weake, that they are drowned by other ftronger motions,whidr 

 round about befiege our eares in fuch manner, that notice is not 

 taken of thefe : for fo it fareth in what dependeth nieerelyof 

 quantity, e/pecially,concerningci!r lenfes, that not every thing 

 of die kind^but a terminate quantity or multitude of parts of it, 

 maketh an objccl fenfible. 



But to come clofe to the point ; we fee that found , for the 

 moftpart,is made. in the tyre j and that to produce it, there is 

 required a quicke and finart motion of that Element, which, of 

 all the reil, is the mod moveable. And in motion, velocity or 

 quicknefle,is proportionate to denfity in magnitude (as wehavc 

 atlart^e declared.) Which maketh quantity become perceptible 

 in bulke.as this doth in motion. And as the one cohf tfteth in a 

 greater proportion of Jubilance to the fame quantity 5 fo the 5 

 other doth in the paflagc of more parts of the medium in the 

 fame time. 



And in the moderating of this , fuch of the liberal! Arts "are 

 employed,whieh belong to the cultivating mans vcyce- as Rhe- 

 toricke.meeteriijgjand finging. It is admirable how finely Ga-
