Miscellany

Since 1840 the Oxford Electric Bell has been ringing in a laboratory at the University of Oxford. Built by a London instrument maker and powered by dry-pile batteries, the bell is said to have rung more than ten billion times. The ring is now barely audible because the charge is so low.

What can you conceive more silly and extravagant than to suppose a man racking his brains and studying night and day how to fly?

—William Law, 1728
