With diminishingwave-length q increases, as shown in fig. 3, where thevalues of q found in Table XII. are graphically indicated,very rapidly to a wave-length of about 0*37, whereuponq continually increases with a still more diminishing wave-length. In regard to the fact that characteristic radiationof the wave-length indicated for J-radiation according towhat has been mentioned by Siegbahn f has not beenpossible to state directly, there is good evidence for believingthat this same increase of scattering within the range of\ = 0*42-0\37 is the cause of the increase of absorption thathas been the occasion of supposing an especial J-radiation. It is seen from the table that q— Cu, beginning at a wave-length
