mix'd and blended together, they will again 

 compofe that Colour, which they did before re- 

 paration. And for the fame reafbn, Tranfmu- 

 tations made by the convening of divers Colours 

 are not real ; for when the difForm Rays are 

 again levered, they will exhibit the very fame 

 Colours, which they did before they entered the 

 Compofition; as you fee, Blue and Yellow Pow- 

 ders, when finely mixed, appear to the naked 

 Eye Green, and yet the Colours of the compo* 

 nent Corpufcles are not thereby really tranfrau- 

 ted, but only blended. For, when viev/ed with 

 a good Microfcope, they ftill appear Blue and 

 Yellow interfperfedly. 



5:. There are therefore two forts of Colours, 

 The one Original and Simple, the other com- 

 pounded of thefe. The Original or Primary 

 Colours are, I{ed, Yellow, Green y Blue, and a 

 Violet-purple, together with Orange, Indico, and 

 an indefinite variety of intermediate Gradations, 



6. The fame Colours in Specie with thefe pri- 

 mary Ones, may be alfb produced by Compoii- 

 tion : For, a mixture of Yellow and Blue makes 

 Green ; of Red and Yellow, makes Oiange ; ol 

 Orange and Yellowifo Green, makes Yellow, And 

 in general, if any two Colours be mix 3 d, which 

 in the Series of thofe, generated by the Prifm, are 

 not too far diftant one from another, they by 

 their mutual Alloy compound that Colour, which 

 in the faid Series appeareth in the mid-way be- 

 tween them. But thofe, which are fituated at 

 too great a diftance, do not fb. Orange and In- 

 dico produce not the intermediate Green, nor Scar- 

 let and Green the intermediate Yellow, 



7. But the moft furprizing and wonderful 

 Compofition was that of Whitenefs. There k 

 no one fort of Rays which alone can exhibit this.
