Abstract
As the hand appears to feel a cold sensation when exposed to the X-rays, an experiment was made with the thermopile to put the matter to the test. This showed that heat was being radiated from the phosphorescent patch in the Crookes' tube; if the current be reversed so as to make the opposite pole the anode, then heat was again radiated, but in a very much smaller amount. The phosphorescent patch becomes very markedly warmed in some tubes. On replacing the thermopile by a lighted candle, the flame exhibited a flickering motion, and was slightly drawn towards the phosphorescent patch; this could be observed at a distance of six inches. The phenomenon was also observed when the candle was placed on the side of the tube opposite the anode, but less markedly. A flame is almost transparent to the X-rays; on taking a shadowgraph of a lighted candle or gas jet, the shadow of the flame is just visible as an exceedingly faint impression, the internal core in the case of the gas flame being slightly more marked than the external.
