_To make a Calve’s Head bellow as if alive, when dressed and served
up._
This is effected by a simple and innocent stratagem; it consists in
what follows: take a frog that is alive, and put it at the farther end
of the calve’s head, under the tongue, which you will let fall over
it; taking care not to put the frog there till the calve’s head is
going to be served up.
The heat of the tongue will make the frog croak; which sound, coming
from the hollow part of the head, will imitate the bellowing of a calf
as if it were alive.
