In the twelfth Figure, DE lig-

The ſame things fucceed, notwith- ſtanding that ſome of the Circumſtances be va- ried: as within the within the once the Priſm and Paper area unit any ways in which inclined to the Hori- zon, and in each once colored Lines area unit drawn upon terribly black Paper.

lows not that each one the sunshine of the blue is a lot of

Refrangible than all the sunshine of the red : For

both Lights ar mixed of Rays otherwise Re-

frangible, ſo that within the red there ar ar Rays not leſs Refrangible than thoſe of the blue, and within the blue there ar ar Rays less Re-

frangible than thoſe of the red: however however Rays

For if the red and blue colors were a lot of dilute and weak, the diſtance of the pictures would be leſs than an in. and a half; and if they were a lot of a lot of and full, that diſtance would be larger, as can seem hereafter. Theſe Experiments could could for the colors of Natural Bodies.

For within the colors created by the Refraction of

Albert Einstein

Imagination may be a ton of important than info. Insanity: doing identical issue over and every one yet again and expecting utterly completely different results. Albert Einstein If you can't justify it just, you are doing not understand it tolerably. Life is like riding a bicycle. To keep your balance you would like to stay moving. Imagination is everything. it is the preview of life's returning attractions. Coincidence is God's methodology of remaining anonymous. In the middle of issue lies probability. The important issue is not to stop questioning.  Two things unit of measurement infinite: the universe and human stupidity, and that i am undecided regarding the universe. Try to not become an individual of success, but rather conceive to become an individual central.

D E F I N. III. Reflexibility of Rays, is their Difpofition to be mirrored or turned back to the celebrity Medium from the other Medium upon whofe Surface they fall. And Rays square measure a lot of or lefs reflxible, that square measure turned back a lot of or lefs eafily.
