As Attraction Is Stronger In Small Magnets Than In Great Ones In Proportion To Their Bulk, And Gravity Is Greater In The Surfaces Of Small Planets Than In Those Of Great Ones In Proportion To Their Bulk, And Small Bodies Are Agitated Much More By Electric Attraction Than Great Ones; So The Smallness Of The Rays Of Light May Contribute Very Much To The Power Of The Agent By Which They Are Refracted.

Do Not The Rays Of Light Which Fall Upon Bodies, And Are Reflected Or Refracted, Begin To Bend Before They Arrive At The Bodies; And Are They Not Reflected, Refracted, And Inflected, By One And The Same Principle, Acting Variously In Various Circumstances?

I Have Not Been Able To Discover The Cause Of Those Properties Of Gravity From Phenomena, And I Frame No Hypotheses; For Whatever Is Not Deduced From The Phenomena Is To Be Called A Hypothesis, And Hypotheses, Whether Metaphysical Or Physical, Whether Of Occult Qualities Or Mechanical, Have No Place In Experimental Philosophy.

It Is Indeed A Matter Of Great Difficulty To Discover, And Effectually To Distinguish, The True Motions Of Particular Bodies From The Apparent; Because The Parts Of That Immovable Space, In Which Those Motions Are Performed, Do By No Means Come Under The Observation Of Our Senses. Yet The Thing Is Not Altogether Desperate; For We Have Some Arguments To Guide Us, Partly From The Apparent Motions, Which Are The Differences Of The True Motions; Partly From The Forces, Which Are The Causes And Effects Of The True Motions.

My Powers Are Ordinary. Only My Application Brings Me Success.
