[B] Study carefully Polarization of the Circuit, page 29.

[C] Polarization of the Circuit, page 29.

[D] By a current of good medium strength, I mean one which, in the hands, is ordinarily felt rather strongly, yet not sufficiently so to produce distress.

[E] See Polarization of the Circuit. Page 29.

Transcriber's Note
