I Not only found by Experience, that those Colours, which are by the Schools, taken to be Phantastical, might be compounded with as much certainty as real ones; but that if those Colours were deficient, the resulting Colour would be so too.

And the blew Part of an Iris cast upon Red CIoth, would turn it Pur∣ple: And by casting one Part of an Iris upon ano∣ther Iris made by another Prism, I could com∣pound Colours, which would answer my expecta∣tion as well as with those that are esteem'd real Co∣lours.
