Natural Magics. < Bgo^ ij,

present Images of any colour. How to mingle the colours, I taught when I spake ofjewels. I have oft made sport with the most fair women, with these Glasseswhenthey looked, and law not themselves as they were: but there are many varieties st-rife from the form.

That the face os him that looks on theGlaJs majfeem to be divided in the middle,

Let the superficies of the looking-glaffe that you look on, be plain, and exactlypolished by rule ; but the backside must have a blunt angle in the middle. that thehighest part of it may be in the middle; in the outward parts it must be fhsrp andpressed down; then lay on the foil: wherefore the Image that falls on you; sight,where the lines meet in the angle, will seem divided into two. If you will

That he that looks in the Glass,jh'all seem like an dss,Dog, or Sow ;

By variation of the place, the Angles, and the representation of the Form beheld, willseem various. If that part of the Glass, that is set against your mouth,{hall stick forthbefore like a wreathed band or a Boss-buckler, your mouth will appear to comeforth like an Asses or Sows snout; but if it iwell forth against your eyes, your eyeswill seem to be put forth like shrimps eyes t if the Angle be stretched forth by thelength of the Glass, your Forehead, Nose, and Chin, will seem to be sharp , as themouth of a Dog.

That the whole face maj seem various and deformed.

Let a plain Glass not be exactly plain and even : which that it may be done, whenthe Glass is once made plain.puc it into the furnace again, and let it be turned by rheskilful hand of an Artist, till ic lose its right position , then foil it. Then the Imageon the hollow part of the Glass, will represent the opposite part hollow; lo it willhold forth one lying along on bis face, or crooked , and swelling outwardly and in-wardly. Then if when the Glass is polished, one side be rubbed, theface will seemlong and broad : wherefore it must be rubbed, and fashioned on all sides, that it mayevery way represent a perfect face. I shall shew you also

H w tom ke a Glass to represent many Images.

That it may shew divers Images one after another, and of divers colours, make thesolid body of the Looking-glass, or Glass that is half a finger thick , and let it be soplained, that upon one fide,the thickness may not be touched, but on the other side,the lines of the two superficies may meet, as the sharp edge of a Knife. Make alsoanother table of a Glass the fame way : or else more; lay a foil of Tin upon the last,and place one of them upon the other, so that the thinner part of the one, may lyeupon the thick part of the other: so will the face of one that looks into it, appearto be two,one behind the other, and the nethermost will always appear daikest. Soif by the fame Artifice, you fit three tables of Glass,the Image will appear to be three,and the farther he that looks, stands with his face from the Glass, the farther willthose Images or faces stand asunder; but as von come very neer, they seem to joynall in one: Ifyou hold a Candle lighted against it, there will be many seen together,which comes by the mutual reciprocation of the sight and the Glaffc ; and if the po-lisher of Glasses be not neer-hand , we may make the fame with common Looking-ing-glsflcs, putting one aptly above another, but let one be distant from the otherbv certain courses; then shut them in a frame , that the Art may not be discovered.N. Twill I omit

How letters may be cast out and read , o» a wall that is far if ant ;

which we shall do with the same plain Glass ; and lovers that are far asunder, mayso hold commerce one with another. On the superficies of a plain Glass, make Let-ter' wi.h Mack ink , or with wax, that they may be solid to hinder the light of theOla! = ,and shadow it ;tben hold thtGlass against the San-beams,so that the beams re-flecting on the Glass, may be cast upon the opposite wall of a Chamber, it is nodoubt but the light and letters will be seen in the Chamber, the Suns light will be' de,rest, -
