We can best describe these byfirst mentioning some of the observationsDr. Rollins has made in connection withx-light, in accordance with which he hasdesigned these tubes. He has shown thatfor practical purposes x-light is a hydro-gen phenomenon, the light originatingin this way: The cathode is a store-house of hydrogen, the particles of whichunder the electric stress are repelled byits concave surface, because, as shown by ish both in amplitude and frequency, forthe particles lose heat rapidly, on ac-count of their small size. As the veloc-ity depends not only upon the degree ofrepulsion between the particles and thecathode, but also upon the attraction ofthe anode, it is evident that the target onwhich they strike should be an anod
