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)—

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]
