ABSORBING POWER AND FLUORESCENCE OF RESORUFIN. 



J 3 



Table 6. 



Observed fluorescence intensity before correction is made for absorption. Meas- 

 urements made according to Method I; iluorescence excitation extending over 

 whole face of cell. 



Table 7. 



Observed fluorescence intensity reduced to such a scale as to make intensity of 

 wave-length o. 589 n the same as observed Iluorescence in Table 9. 



Corrected Iluorescence. 



Table 8. 



Value of f calculated from Table 6 according to 

 formula/ = 7/3/(1 e-0). 



Table 9. 

 Intensity of fluorescence of different concentrations at wave-length 0.589 ft.
