Shape out a doll, A B, of light material, and paint or dress him
prettily, as your fancy suggests, and between his legs set the cone, C,
made of thin sheet-copper.
[Illustration: Fig. 107.]

balance itself on the top, while rising and falling divertingly.
A hollow copper ball, an inch in diameter, will balance itself in the
like manner, turning continually round its centre, and casting the water
from its surface.
