The insulated plate con­ ducting-body should present large sur­ face practicable the rays streams 80 matter, having ascertained that the amount of energy conveyed per unit time is under otherwise identical conditions propor- -— tionate the area exposed, nearly so. Roentgen rays, the like—possess the prop­ erty charging and discharging conductors iS electricity, the discharge being particu­ larly noticeable when the conductor upon which the rays impinge negatively electri­ fied.

These radiations are generally con­ sidered ether vibrations extremely zo small wave lengths, and explanation the phenomena noted has been assumed by some authorities that they ionize render conducting the atmosphere through which they are propagated.
