The term pince-nez comes from the French words pincer, meaning 'to pinch' and nez, meaning 'nose'.  Pince-nez spectacles do not have earpieces and are kept in place with a solid bridge piece which pinches the nose.  They were popular with both men and women during the 19th century but are much less common today.

Carrier pigeons are homing pigeons that can be used to carry messages.  Homing pigeons are able to find their way home even from a very long distance away.  If a message is written on lightweight paper and rolled into a small tube, it can be attached to the pigeon's leg.  The bird will then carry the message back to its home.

Carrier pigeons have been used throughout history and played a vital role in delivering important intelligence during World War I and World War II.
