Erratic Results Obtained with Dilution of Luciferin Solutions. 



I am not able to state what uncontrolled factor has been at work 

 in these dilution experiments to produce this curious acceleration of 

 velocity at lower concentrations of the luciferin. It may possibly 

 be a difference in pH, or in salt concentration. In any case I 

 have been able to determine that these results do not represent the 

 real effect of changing luciferin concentration alone.
