Who was frightened by a Passing Motor, and was brought to Reason.
From Cautionary Tales for Children, by Hilaire Belloc. (Project Gutenberg version)

“Oh, Murder! What was that, Papa!”
“My child, It was a Motor-Car,
A Most Ingenious Toy!

Designed to Captivate and Charm
Much rather than to rouse Alarm
In any English Boy.

“What would your Great Grandfather who
Was Aide-de-Camp to General Brue,
And lost a leg at Waterloo,
And Quatre-Bras and Ligny too!

And died at Trafalgar!—

What would he have remarked to hear
His Young Descendant shriek with fear,
Because he happened to be near
A Harmless Motor-Car!

But do not fret about it! Come!
We’ll off to Town
And purchase some!”
