The Mad Hatter in the Tea party - Alice in Wonderland - was mad, I think,
because hatters used mercury and it caused brain damage. That takes it back
to the mid-1800's. People used mercury mouthwashes in attempts to cure
venereal disease (the pox) back to Elizabethan times - they did notice that
their teeth fell out!
