This can easily be done by showing them that their shad-
ow on the wall is made by th mselves ; that when they
raise their hands, it produces a correspondent mo.tion in
the shadow, and when they run, the shadow runs. If a
child is amused with seeing the rabbit on the wall open
and shut its mouth, dart forward and then back, he should
not be left with the impression that there was some real
and mysterious being who thus appeared and disappeared ;
but by directing his attention to the hand and the motion
of the fingers, he is let into the secret, and ready to laugh
at the joke, instead of being left in that excited state of
mind which makes him feel terrified at every unusual sight
or sound.
