OF BODIES, Chap.XXVIIII. 3 i 5 



Jy, the patfion of our eye born fuc'i objects mutt be divers. But 

 I ;iere is no other ducr.it y of paifion in the eye from the o'jject 

 wi regard of feeing , but that the object appcare di vers to us in 

 peint of colour. Therefore we mutt conclude, that divers bo- 

 dies ( I meane divers or different , in that kind wee here talke 

 of) uuifl necefliin.'y fceme to be of diver.? colours, mcerly b/ 

 the ten Jing of light mno our eye in divers feiniom. Nay /the 

 very lame object mult appears of different colours, when foever 

 it happeneth that it reflected! light differently to us. As we fee 

 in c'otu, if it be gathered together in fouldes, the bottomes of 

 thole fouldes fhew to be of one kind of colour, and the tops of 

 them, or where the cloth is Wretched out td the lull percutfion 

 of light, it appeareth to be of an other much brighter colour. 

 And accordingly painters are fainc co ule almott opposite co- 

 lours to expreiTe them . In like manner if you looke upon two 

 pieces of the fame cloth, or plulh, whofe graines lye contrawife 

 to one an other, they will likevife app^are to be of different 

 colours. Both which accidents, and many others like unto- 

 them in begetting various reprctentations of colours ; do all of 

 them ariie out of lights being more or lefle reflected from one 

 par^ th$n ftpm an other. 



TiWlh^i you fee, how colour is nothing elfe, but the difpo- T .. ' 

 fition pfa bodies fupperficks, as it is more or Jefle apt to reflect " t y W f ^100"$ 

 ligh.t;fithcnce the reflection of light is made from thefijper- do follow out 

 ficies of the feen body.,and the varictyjof its reflexion begetteth of various de- 

 variety of colours. But a fuperficies is more or Jefle apt to re- rec 

 flc<ft light, according to the degrees of its bein^ more or lefle 

 penetrable by the force of light ftriking upon it } for tho/e rayes 

 of light that gain* no oatranee into a body they are darted up* 

 on, murtofneceffityflybackagaine from it. Butif light doth 

 get eac.ra.nce and penetrate into the body , it either pafl^tft 

 quite through it ;or elle it is fwallowed up and loft in that bocfy. 

 The former,conttituteth a diaphanous body ; as we have already 

 determined. And the femblance which the latter will have in re- 

 gajrd of colour.wc have alu> mewed mult be black. 



ut let us proceede, a little further. Wee know that two 

 things render a body penetrable, or ea/ie to admit an other bo-
