When Newton saw an apple fall, he found

In that slight startle from his contemplation—

'T is said (for I'll not answer above ground

For any sage's creed or calculation)—

A mode of proving that the Earth turned round

In a most natural whirl, called "gravitation;"

And this is the sole mortal who could grapple,[JT]Since Adam—with a fall—or with an apple.[JU] [525]
