It will be observed that these curves are similar in form, the maximum wave-length being approximately the same, about fi. For purposes of comparison a series of measurements was made to determine the relative intensity of different concentrations at wave-length n, keeping all conditions constant. Table 9 shows the results. In Fig. t,^ the curve marked O gives the actual observed fluorescence. The 200 ""*c •50 100.
