COLOUR, may be considered two ways,

1, As it is a Quality redding in the Body that islaid to be so and so coloured, or which doth mo-dify the Light alter such and iuch a manner.- Or

2. As more properly, the Light it self which 10modified strikes upon the Organ of Sighs, andproduces that Sensation which we call Colour.

The Peripateticks assert Colours to be real Qua-lities, and inherent in the coloured Bodies, andsuppose that Light doth only dilcover them, butnot any effect of their Production.

Plato thought Colour to be a kind of Flame con-sisting of most minute Particles, very congruousto the Pores of the liye, and darted against itfrom the Object. And lome Moderns will haveColour to be a kind of Internal Light of the morelucid parts of the Object, darkened, and conle-qucntly altered by the various mixtures ol the le!5Luminous Parts.

Others, as did some of the Ancient Atomists,maintain Colour not to be a Lucid Stream, but aCorporeal Effluvium issuing out of the colouredBody.

Others account for all Colours out of the variousmixture of Light and Darknels ; and the Cliy-mists sometimes will have it arile from the Sul-phur and sometimes from the Salt that is in Bo-dies ; and some also from the third HypostatickPrinciple, Mercury.

The Cartesians , who make the Sensation ofLight to be the Impulse made en the Fye by cer-tain solid but very minute Globules easily permea-ting the Pores of the Air and Diaphanous Bodies.These, I lay, derive Colour from the various Pro-portion of the direct Progrcls or Motion of theseGlobules, to their Circumrotation or Motionround their own Centres; by which means theyarc qualified to strike the Optick Nerve after di-stinct and divers manners, and so do produce thePerception of various Colours.

Dr. llool^ in his Micrographs a fays, The Phan-tasm of Colour is caused by the Senlatjon of theoblique or uneven Pulse of Light; and that this iscapable of no more Varieties than two, which a-rifeTrom the two fides ot the Oblique Pulse ; sothat there is in reality but two simple Colours,Yellow and Blue ; from the Mixture of which,and a due proportion of Black and White (that is*Darknels and Light) all Colours may be pro-duced.

The incomparable Mr. If. Kcxvton found by twoExperiments on Prisms, that there is a great dif-formiry in the Rays of Light ; and that herebythe Origin of Colours may be unfolded. The Do-ctrine therefore of Colours accbrding to his Notionand Experiments are contained in the followingPropositions.

1. As the Rays of Eight differ in degrees ofRcfrangibility, so they also differ in their Disposi-tion to exhibit this or that particular Colour.

Colours arc not Qualifications of Light, derivedfrom Refractions, or Reflections of Natural Bo-dies (as 'tis generally believed) but Original andConnate Properties which in divers Rays are divers..Some Rays are disposed to exhibit a Red Colourand no other; some a Yellow and no other; some

a Green
