J. Thomsons Recent Researches, p. 395. WORK OF HERTZ LECTURE. 7 A closed circuit such as this is a feeble radiator and a feebleabsorber, so it is not adapted for action at a distance. In fact,I doubt whether it will visibly act at a range beyond the JA atwhich true radiation of broken-off energy occurs. If the coat-ings of the jar are separated
