White appears the brighter, as the Ground it is found on, is more obscure, and on the contrary, more obscure, as its Ground is more White: This is visible in Fleeces of Snow, which, while they are floating in the Air illumined on every side, appear less White, than when viewed over against an open Window, where the Obscurity within-side makes a dark Ground, and sets off the falling Fleeces with an exquisite White. It must likewise be observed, that Snow when viewed near at hand, seems to fall with Quickness, and in large continued Quantities; whereas, at a distance, it appears in small Flakes, and those descending very slowly.
