To Every Action There Is

...from The Same Principles, I Now Demonstrate The Frame Of The System Of The World.

Doth Not This Æthereal Medium In Passing Out Of Water, Glass, Crystal, And Other Compact And Dense Bodies Into Empty Spaces, Grow Denser And Denser By Degrees, And By That Means Refract The Rays Of Light Not In A Point, But By Bending Them Gradually In Curve Lines? And Doth Not The Gradual Condensation Of This Medium Extend To Some Distance From The Bodies, And Thereby Cause The Inflexions Of The Rays Of Light, Which Pass By The Edges Of Dense Bodies, At Some Distance From The Bodies?

This Excellent Mathematician Having Given Us, In The Transactions Of February Last, An Account Of The Cause, Which Induced Him To Think Upon Reflecting Telescopes, Instead Of Refracting Ones, Hath Thereupon Presented The Curious World With An Essay Of What May Be Performed By Such Telescopes; By Which It Is Found, That Telescopical Tubes May Be Considerably Shortened Without Prejudice To Their Magnifiying Effect. On His Invention Of The Catadioptrical Telescope, As He Communicated To The Royal Society.

If I Am Anything, Which I Highly Doubt, I Have Made Myself So By Hard Work.

What Goes Up Must Come Down.
