make white and grant further that all luminous bodies are compounded of such substances condensed and that whilst they shine they doe continually send out on indefinite quantity thereof every way in ortem which in a moment of tyme doth disperse it selfe to the outmost and most indefinite bounds of the universe, granting shape, I say I doe suppose there will be noe difficulty to demonstrare all the rest of his curious Theory. Though yelt me thinkes all the coloured bodyes in the World compounded together should not make a white body and I should be glade to se an experiment of that kind done on the other side if my supposition be granted, that light is nothing but a simple and uniforme motion or puls of a homogenious and adopted (that is a transparent) medium propagated from the Luminous body in ortem to all immaginable distances in a moment of tyme and that that motion is first begun by some other kind of motion in the Luminous body. such as by the dissolution of Sulphureous body by the aire. or by the working of the aire or the sever all component parts one upon another in Rotten wood, or putrefieing fish or by an externall stroke as in diamant, sugar the Sea water or two [text?] or cristall rubbed together and that this motion is propagated through all bodies susceptible thereof, but is blinded or mixt with other advantitious motions generated by the obliquity of the stroke upon a refracting body, and that soe long as those motions remain distinct in the same part of the medium or propagated. Ray soe long they produce the same effect, but when blended by other motions they produce other effects and supposeing that by a direct contrary motion to the newly impressed that adventious on be destroyed and reduced to the first simple motion. I believe M<sup>r</sup> Newton will thinke it noe difficult matter by my hypothesis to solve all the Phanomena, not onily of the prisme tinged liquors and solid bodyes but of the Colours of plated Bodys which seeme to have the greatest difficulty His true. I can in my supposition conceive the white or uniforme motion of light to be compounded of the compound motions of all the other colours, as any on straight and uniforme motion may be compounded of thousands of compound motions in the same manner as Descartes explicates the reason of the refraction but noe necessity of it [text?] M<sup>r</sup> Newton hath any
