The following procedure was believed to eliminate an enchantment. A person would lick a child’s forehead, first in an upward direction, then across the forehead, and finally upward again. Then the person would spit behind the child’s back.

It was thought that when licking the child’s forehead with the tongue, if the taste of salt was perceived then that was an infallible proof of fascination, or the enchantment was exterminated. A.G.H.
