The wild girl of Champagne had probably learned to speak before her abandonment, for she is a rare example of a wild child learning to talk coherently – although she could remember little of her feral existence, which she thought had lasted two years. When coaxed from a tree in Songi near Chalons in the French district of Champagne in 1731, she was aged about 10, barefoot, and dressed in rags and skins with a gourd leaf on her head. In a pouch she carried a cudgel and a knife inscribed with indecipherable characters. She shrieked and squeaked, and was so dirty (or possibly painted) that she was mistaken for a black child. Her diet consisted of birds, frogs and fish, leaves, branches and roots. Given a rabbit, she immediately skinned and devoured it.

I think I dated her in college. Many thanks to Joerizilla for the link.
