Excerpt from Opticks: Or, a Treatise of the Reflections, Refractions, Inflections and Colours of Light These matters, I have hitherto delayed the printing, and should still have delayed it, had not the Importunity of friends prevailed upon me. If any other Papers writ on this Subject are got out of my Hands they are imperfect, and were perhaps written before I had tried all the Experiments here set down, and fully satisfied myself about the Laws of Refractions and Composition of Colours. I have here publish'd what I think proper to come abroad, wishing that it may not be translated into another Language without my Consent.
