Professor Joseph Henry, then ateacher in the Albany Academy, starting with the feeble electro-magnetof Sturgeon, reconstructed and improved it, and then by a series of brill-iant original discoveries and experimental researches developed it intoan instrumentality of enormous mechanical power.

The subject has steadily advanced in public interest andimportance, extending in unexpected directions and linking itself withdepartments of science with which it was not supposed to have any rela-tion. Franklin subjected electricity to every test and every influence thatthe most fertile brain could suggest. He brought the lightning into his

Experiments with lightning were in the highest degreedangerous as well as fascinating, and Franklin himself accidentally sufferedseveral severe shocks.
