Bait, hook, and hair, are used by angler fine;
Emma's bright hair alone were bait, hook, line.

Faraday was the first to elicit the electric spark from the magnet; he
found that it is visible at the instants of breaking and of renewing the
contact of the conducting wires; and _only then_.
Around the magnet, Faraday
Is sure that Volta's lightnings play;
But _how_ to draw them from the wire?
He took a lesson from the heart:
'Tis when we meet, 'tis when we part,
Breaks forth the electric fire.
