And from what laws the attractive functions spring.
(The Magnet’s name the observing Grecians drew
From the Magnet’s region where it grew.)
Its viewless, potent, virtues men surprise;
Its strange effects they view with wondering eyes,
When without aid of hinges, links or springs,
A pendent chain we hold of steely rings,
Dropt from the stone; the stone the binding source,
Ring cleaves to ring, and owns magnetic force;
Those held superior those below maintain;
