44 THE PROPERTIES AND QUALITIES 



soever that yt be : As yf that yt were people, 

 yow shall see them thoroughe the Glasse, theyre 

 heades downwardes, and theyre feete vpwardes, 

 theire righte hande turned to theyre lefte hande, 

 &c. So that this kynde of Glasse beynge thus 

 grounde hathe three marvellous qualityes. For 

 at some assigned, or appoynted distance, accord- 

 inge vnto the gryndinge of the Glasse, bothe in 

 his diameter, and thicknes in the middle, and 

 thinnes towardes the sydes. That (beholdinge 

 any thinge thorowe the glasse) yt shall make 

 the best perspective beame : So that the thinge 

 that yow doo see thorowe shall seeme very large 

 and greate : and more perfitter withall. And 

 allso standing further from the glasse yow shall 

 discerne nothinge thorowe the glasse : But like 

 a myst, or water : And at that distance ys 

 the burninge beame, when that yow do holde 

 yt so that the sunne beames dothe pearce 

 thorowe yt. And allso yf that yow do stande 

 further from the glasse, and beholde any thinge 

 thorowe the glasse, Then you shall see yt re- 

 versed and turned the contrary way, as before 

 ys declared. So that accorclinge vnto youre 

 severall standinge, nearer, or furder from the 

 Glasse, beholding any thinge thorowe yt. Suche, 

 yt hathe his perspective beame : and then stand- 

 inge furder from the glasse, and then all thinges 

 seen thorowe, shall shewe vnto the sighte of your 

 eye, cleene turned, and reversed another way, 

 whatsoever that yt bee.
