sealing-wax and amber. He showed them that feathers and bits of paper were now attracted, and now repelled, by electricity, and explained to them the reason of it. He did all kinds of experiments with electricity, and showed them all to his students.
Once his wife grew ill. He called a doctor and asked him how to cure her. The doctor told him to prepare a frog soup for her. Galvani gave order to have edible frogs caught. They caught them for him, killed them, and left them on his table.
Before the cook came after the frogs, Galvani kept on showing the electric machine to his students, and sending sparks through it.
Suddenly he saw the dead frogs jerk their legs on the table. He watched them, and saw that every time when he sent a spark through the machine, the frogs jerked their legs. Galvani collected more frogs, and began to experiment with them. And every time he sent a spark through the machine, the dead frogs moved their legs as though they were alive.
