Excerpt from Wireless Course in Twenty Lessons, Vol. 1
While a charge may be given to a body by contact, it is also possible to charge a body at a distance, and by what is known as induction. If an electrified rod is brought near a glass cylinder, the latter will receive a temporary charge which disappears again when the rod is removed from the vicinity of the cylinder. However, if 'a permanent charge is desired, the glass cylinder is touched by the hand while the rod is held in the other hand near the end Opposite to that being touched. A body touched or grounded while near a charged body is electrified Oppositely. A body brought near a charge of electricity is electrified oppositely on the near end and similarly on the far end.
The following table represents electrical conductors and non-conductors in their respective value.
