nwiiiiT Fig. 8—Light scattered by a quartz crystal; unshifted line is 2536, lines denotedby S and A are shifted towards lower and higher frequencies respectively. (F. G.Brickwedde.) quency; its excessive width is due to the great intensity of this light.The lines marked S21 and S81 consist of quanta which have spentpart of their energy in exciting vibrations, those corresponding tothe Reststrahlen of wave-lengths 21^ and 81^ respectively. Thelines marked A21 and A81 consist of quanta which have receivedenergy from these vibrations. These Anti-Stokesian lines evidentlygrow more intense as the temperature of the crystal is raised, as theyshould, for the reason which I have already stated: as the substancegrows warmer, the percentage of the molecules spontaneously invibration is increased. In addition, the shifted lines all move inwardtoward the position of the unshifted light as the temperature rises—one may see this by comparing those on the low-frequency side with ^^ I am much obl
