- ‘Most other minerals are non-conductors of electricity.’
- ‘A non-conductor can be charged by induction by exposure to an electrostatic field that is present on a surface charged with static electricity.’
- ‘They terminate at the surfaces of the conductors under induction, or at the particles of non-conductors, which, being electrified, are in that condition.’
