Occasion'd by the fall of an apple

The famous apple-tree story, from a manuscript by one of Newton's friends:

"After dinner, the weather being warm, we went into the garden and drank tea, under the shade of some apple trees. [Newton] told me, he was just in the same situation, as when formerly, the notion of gravitation came into his mind. It was occasion'd by the fall of an apple, as he sat in contemplative mood.

'Why should that apple always descend perpendicularly to the ground,' thought he to himself. 'Why should it not go sideways, or upwards? But constantly to the earth's centre? Assuredly, the reason is, that the earth draws it. There must be a drawing power in matter.'"

(I've linked to my own article about this under my name.) It's great reading some of these old accounts. The English can be very florid, quaint (to our eyes), yet still readable.
